# Description
Close: #9673Close: #8277Close: #10944
This pr introduces the following syntax:
1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu
--testbin echo_env_stderr FOO e>| str length`
2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command,
example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>|
str length`
Note: it only works for external commands. ~There is no different for
internal commands, that is, the following three commands do the same
things:~ Edit: it raises errors if we want to pipes for internal
commands
```
❯ ls e>| str length
Error: × `e>|` only works with external streams
╭─[entry #1:1:1]
1 │ ls e>| str length
· ─┬─
· ╰── `e>|` only works on external streams
╰────
❯ ls e+o>| str length
Error: × `o+e>|` only works with external streams
╭─[entry #2:1:1]
1 │ ls e+o>| str length
· ──┬──
· ╰── `o+e>|` only works on external streams
╰────
```
This can help us to avoid some strange issues like the following:
`$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length`
Which is hard to understand and hard to explain to users.

# Description
Does a little cleanup in `record.rs`:
- Makes the `record!` macro more hygienic.
- Converts regular comments to doc comments from #11718.
- Converts the `Record` iterators to new types.
# Description
Previously, only direcly-recursive calls were checked for recursion
depth. But most recursive calls in nushell are mutually recursive since
expressions like `for`, `where`, `try` and `do` all execute a separte
block.
```nushell
def f [] {
do { f }
}
```
Calling `f` would crash nushell with a stack overflow.
I think the only general way to prevent such a stack overflow is to
enforce a maximum call stack depth instead of only disallowing directly
recursive calls.
This commit also moves that logic into `eval_call()` instead of
`eval_block()` because the recursion limit is tracked in the `Stack`,
but not all blocks are evaluated in a new stack. Incrementing the
recursion depth of the caller's stack would permanently increment that
for all future calls.
Fixes#11667
# User-Facing Changes
Any function call can now fail with `recursion_limit_reached` instead of
just directly recursive calls. Mutually-recursive calls no longer crash
nushell.

Fixes https://github.com/nushell/nushell/issues/11716
The problem is in our [record creation
API](0d518bf813/crates/nu-protocol/src/value/record.rs (L33))
which panics if the numbers of columns and values are different. I added
a safe variant that returns a `Result` and used it in the `rotate`
command.
## TODO in another PR:
Go through all `from_raw_cols_vals_unchecked()` (this includes the
`record!` macro which uses the unchecked version) and make sure that
either
a) it is guaranteed the number of cols and vals is the same, or
b) convert the call to `from_raw_cols_vals()`
Reason: Nushell should never panic.

# Description
Fixes: #11394
When run `^sleep 3` we have an `exit_code ListStream`, and when we press
ctrl-c, this `ListStream` will return None. But it's not expected,
because `exit_code` sender in `run_external` always send an exit code
out.
This pr is trying to fix the issue by introducing a `first_guard` into
ListStream, it will always generate a value from underlying stream if
`first_guard` is true, so it's guarantee to have at least one value to
return.
And the pr also do a little refactor, which makes use of
`ListStream::from_stream` rather than construct it manually.

> Revert the logic in https://github.com/nushell/nushell/pull/10694 and
apply the logic in this pr to mv, cp, rv will require a larger change, I
need to think how to achieve the bahavior
And sorry @bobhy for reverting some of your changes.
This pr is going to unify glob behavior on the given commands:
* open
* rm
* cp-old
* mv
* umv
* cp
* du
So they have the same behavior to `ls`, which is:
If given parameter is quoted by single quote(`'`) or double quote(`"`),
don't auto-expand the glob pattern. If not quoted, auto-expand the glob
pattern.
Fixes: #9558Fixes: #10211Fixes: #9310Fixes: #10364
# TODO
But there is one thing remains: if we give a variable to the command, it
will always auto-expand the glob pattern, e.g:
```nushell
let path = "a[123]b"
rm $path
```
I don't think it's expected. But I also think user might want to
auto-expand the glob pattern in variables.
So I'll introduce a new command called `glob escape`, then if user
doesn't want to auto-expand the glob pattern, he can just do this: `rm
($path | glob escape)`

## NOTE
This pr changes the semantic of `GlobPattern`, before this pr, it will
`expand path` after evaluated, this makes `nu_engine::glob_from` have no
chance to glob things right if a path contains glob pattern.
e.g: [#9310
](https://github.com/nushell/nushell/issues/9310#issuecomment-1886824030)
#10211
I think changing the semantic is fine, because it makes glob works if
path contains something like '*'.
It maybe a breaking change if a custom command's argument are annotated
by `: glob`.
# Description
The `cell-path` is a type that can be created statically with
`$.nested.structure.5`, but can't be created from user input. This makes
it difficult to take advantage of commands that accept a cell-path to
operate on data structures.
This PR adds `into cell-path` for dynamic cell-path creation.
`into cell-path` accepts the following input shapes:
* Bare integer (equivalent to `$.1`)
* List of strings and integers
* List of records with entries `value` and `optional`
* String (parsed into a cell-path)
## Example usage
An example of where `into cell-path` can be used is in working with `git
config --list`. The git configuration has a tree structure that maps
well to nushell records. With dynamic cell paths it is easy to convert
`git config list` to a record:
```nushell
git config --list
| lines
| parse -r '^(?<key>[^=]+)=(?<value>.*)'
| reduce --fold {} {|entry, result|
let path = $entry.key | into cell-path
$result
| upsert $path {||
$entry.value
}
}
| select remote
```
Output:
```

```
## Errors
`lex()` + `parse_cell_path()` are forgiving about what is allowed in a
cell-path so it will allow what appears to be nonsense to become a
cell-path:
```nushell
let table = [["!@$%^&*" value]; [key value]]
$table | get ("!@$%^&*.0" | into cell-path)
# => key
```
But it will reject bad cell-paths:
```
❯ "a b" | into cell-path
Error: nu:🐚:cant_convert
× Can't convert to cell-path.

This PR will allow string interpolation at parse time.
Since the actual config hasn't been loaded at parse time, this uses the
`get_config()` method on `StateWorkingSet`. So file sizes and datetimes
(I think those are the only things whose string representations depend
on the config) may be formatted differently from how users have
configured things, which may come as a surprise to some. It does seem
unlikely that anyone would be formatting file sizes or date times at
parse time. Still, something to think about if/before this PR merged.
Also, I changed the `ModuleNotFound` error to include the name of the
module.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Users will be able to do stuff like:
```nu
const x = [1 2 3]
const y = $"foo($x)" // foo[1, 2, 3]
```
The main use case is `use`-ing and `source`-ing files at parse time:
```nu
const file = "foo.nu"
use $"($file)"
```
If the module isn't found, you'll see an error like this:
```
Error: nu::parser::module_not_found
× Module not found.
╭─[entry #3:1:1]

help: module files and their paths must be available before your script is run as parsing occurs before anything is evaluated

Although there's user-facing changes, there's probably no need to change
the docs since people probably already expect string interpolation to
work at parse time.
Edit: @kubouch pointed out that we'd need to document the fact that
stuff like file sizes and datetimes won't get formatted according to
user's runtime configs, so I'll make a PR to nushell.github.io after
this one

# Description
Fixes: #11455
### For arguments which is annotated with `:path/:directory/:glob`
To fix the issue, we need to have a way to know if a path is originally
quoted during runtime. So the information needed to be added at several
levels:
* parse time (from user input to expression)
We need to add quoted information into `Expr::Filepath`,
`Expr::Directory`, `Expr::GlobPattern`
* eval time
When convert from `Expr::Filepath`, `Expr::Directory`,
`Expr::GlobPattern` to `Value::String` during runtime, we won't auto
expanded the path if it's quoted
### For `ls`
It's really special, because it accepts a `String` as a pattern, and it
generates `glob` expression inside the command itself.
So the idea behind the change is introducing a special SyntaxShape to
ls: `SyntaxShape::LsGlobPattern`. So we can track if the pattern is
originally quoted easier, and we don't auto expand the path either.
Then when constructing a glob pattern inside ls, we check if input
pattern is quoted, if so: we escape the input pattern, so we can run `ls
a[123]b`, because it's already escaped.
Finally, to accomplish the checking process, we also need to introduce a
new value type called `Value::QuotedString` to differ from
`Value::String`, it's used to generate an enum called `NuPath`, which is
finally used in `ls` function. `ls` learned from `NuPath` to know if
user input is quoted.
# User-Facing Changes
Actually it contains several changes
### For arguments which is annotated with `:path/:directory/:glob`
#### Before
```nushell
> def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a

> def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
> def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
```
#### After
```nushell
> def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
> def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
> def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a')
~/a
~/a
```
### For ls command
`touch '[uwu]'`
#### Before
```

# Description
Adds a CLI flag for nushell that disables reading and writing to the
history file. This will be useful for future testing and possibly our
users as well. To borrow `fish` shell's terminology, this allows users
to start nushell in "private" mode.
# User-Facing Changes
Breaking API change for `nu-protocol` (changed `Config`).
# Description
When nushell calls a plugin it now sends a configuration `Value` from
the nushell config under `$env.config.plugins.PLUGIN_SHORT_NAME`. This
allows plugin authors to read configuration provided by plugin users.
The `PLUGIN_SHORT_NAME` must match the registered filename after
`nu_plugin_`. If you register `target/debug/nu_plugin_config` the
`PLUGIN_NAME` will be `config` and the nushell config will loook like:
$env.config = {
# ...
plugins: {
config: [
some
values
]
}
}
Configuration may also use a closure which allows passing values from
`$env` to a plugin:
$env.config = {
# ...
plugins: {
config: {||
$env.some_value
}
}
}
This is a breaking change for the plugin API as the `Plugin::run()`
function now accepts a new configuration argument which is an
`&Option<Value>`. If no configuration was supplied the value is `None`.
Plugins compiled after this change should work with older nushell, and
will behave as if the configuration was not set.
Initially discussed in #10867
# User-Facing Changes
* Plugins can read configuration data stored in `$env.config.plugins`
* The plugin `CallInfo` now includes a `config` entry, existing plugins
will require updates

# Description
1. Make table to be a subtype of `list<any>`, so some input_output_types
of filter commands are unnecessary
2. Change some commands which accept an input type, but generates
different output types. In this case, delete duplicate entry, and change
relative output type to `<any>`
Yeah it makes some commands more permissive, but I think it's better to
run into strange issue that why my script runs to failed during parse
time.

# Description
Fixes: #11438
Take the following as example:
```nushell
def spam [foo: string] {
$'foo: ($foo | describe)'
}
def outer [--foo: string] {
spam $foo
}
outer
```
When we call `outer`, type checker only check the all for `outer`, but
doesn't check inside the body of `outer`. This pr is trying to introduce
a type checking process through `Type::is_subtype()` during eval time.
## NOTE
I'm not really sure if it's easy to make a check inside the body of
`outer`. Adding an eval time type checker seems like an easier solution.
As a result: `outer` will be caught by runtime, not parse time type
checker

This PR will allow spreading arguments to commands (both internal and
external). It will also deprecate spreading arguments automatically when
passing to external commands.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
- Users will be able to use `...` to spread arguments to custom/builtin
commands that have rest parameters or allow unknown arguments, or to any
external command
- If a custom command doesn't have a rest parameter and it doesn't allow
unknown arguments either, the spread operator will not be allowed
- Passing lists to external commands without `...` will work for now but
will cause a deprecation warning saying that it'll stop working in 0.91
(is 2 versions enough time?)
Here's a function to help with demonstrating some behavior:
```nushell
> def foo [ a, b, c?, d?, ...rest ] { [$a $b $c $d $rest] | to nuon }
```
You can pass a list of arguments to fill in the `rest` parameter using
`...`:
```nushell
> foo 1 2 3 4 ...[5 6]
[1, 2, 3, 4, [5, 6]]
```
If you don't use `...`, the list `[5 6]` will be treated as a single
argument:
```nushell
> foo 1 2 3 4 [5 6] # Note the double [[]]
[1, 2, 3, 4, [[5, 6]]]
```
You can omit optional parameters before the spread arguments:
```nushell
> foo 1 2 3 ...[4 5] # d is omitted here
[1, 2, 3, null, [4, 5]]
```
If you have multiple lists, you can spread them all:
```nushell
> foo 1 2 3 ...[4 5] 6 7 ...[8] ...[]
[1, 2, 3, null, [4, 5, 6, 7, 8]]
```
Here's the kind of error you get when you try to spread arguments to a
command with no rest parameter:
And this is the warning you get when you pass a list to an external now
(without `...`):

Added tests to cover the following cases:
- Spreading arguments to a command that doesn't have a rest parameter
(unexpected spread argument error)
- Spreading arguments to a command that doesn't have a rest parameter
*but* there's also a missing positional argument (missing positional
error)
- Spreading arguments to a command that doesn't have a rest parameter
but does allow unknown arguments, such as `exec` (allowed)
- Spreading a list literal containing arguments of the wrong type (parse
error)
- Spreading a non-list value, both to internal and external commands
- Having named arguments in the middle of rest arguments
- `explain`ing a command call that spreads its arguments

# Examples
Suppose you have multiple tables:
```nushell
let people = [[id name age]; [0 alice 100] [1 bob 200] [2 eve 300]]
let evil_twins = [[id name age]; [0 ecila 100] [-1 bob 200] [-2 eve 300]]
```
Maybe you often find yourself needing to merge multiple tables and want
a utility to do that. You could write a function like this:
```nushell
def merge_all [ ...tables ] { $tables | reduce { |it, acc| $acc | merge $it } }
```
Then you can use it like this:
```nushell
> merge_all ...([$people $evil_twins] | each { |$it| $it | select name age })
╭───┬───────┬─────╮
│ # │ name │ age │
├───┼───────┼─────┤
│ 0 │ ecila │ 100 │
│ 1 │ bob │ 200 │
│ 2 │ eve │ 300 │
╰───┴───────┴─────╯
```
Except they had duplicate columns, so now you first want to suffix every
column with a number to tell you which table the column came from. You
can make a command for that:
```nushell
def select_and_merge [ --cols: list<string>, ...tables ] {
let renamed_tables = $tables
| enumerate
| each { |it|
$it.item | select $cols | rename ...($cols | each { |col| $col + ($it.index | into string) })
};
merge_all ...$renamed_tables
}
```
And call it like this:
```nushell
> select_and_merge --cols [name age] $people $evil_twins
╭───┬───────┬──────┬───────┬──────╮
│ # │ name0 │ age0 │ name1 │ age1 │
├───┼───────┼──────┼───────┼──────┤
│ 0 │ alice │ 100 │ ecila │ 100 │
│ 1 │ bob │ 200 │ bob │ 200 │
│ 2 │ eve │ 300 │ eve │ 300 │
╰───┴───────┴──────┴───────┴──────╯
```
---
Suppose someone's made a command to search for APT packages:
```nushell
# The main command
def search-pkgs [
--install # Whether to install any packages it finds
log_level: int # Pretend it's a good idea to make this a required positional parameter
exclude?: list<string> # Packages to exclude
repositories?: list<string> # Which repositories to look in (searches in all if not given)
...pkgs # Package names to search for
] {
{ install: $install, log_level: $log_level, exclude: ($exclude | to nuon), repositories: ($repositories | to nuon), pkgs: ($pkgs | to nuon) }
}
```
It has a lot of parameters to configure it, so you might make your own
helper commands to wrap around it for specific cases. Here's one
example:
```nushell
# Only look for packages locally
def search-pkgs-local [
--install # Whether to install any packages it finds
log_level: int
exclude?: list<string> # Packages to exclude
...pkgs # Package names to search for
] {
# All required and optional positional parameters are given
search-pkgs --install=$install $log_level [] ["<local URI or something>"] ...$pkgs
}
```
And you can run it like this:
```nushell
> search-pkgs-local --install=false 5 ...["python2.7" "vim"]
╭──────────────┬──────────────────────────────╮
│ install │ false │
│ log_level │ 5 │
│ exclude │ [] │
│ repositories │ ["<local URI or something>"] │
│ pkgs │ ["python2.7", vim] │
╰──────────────┴──────────────────────────────╯
```
One thing I realized when writing this was that if we decide to not
allow passing optional arguments using the spread operator, then you can
(mis?)use the spread operator to skip optional parameters. Here, I
didn't want to give `exclude` explicitly, so I used a spread operator to
pass the packages to install. Without it, I would've needed to do
`search-pkgs-local --install=false 5 [] "python2.7" "vim"` (explicitly
pass `[]` (or `null`, in the general case) to `exclude`). There are
probably more idiomatic ways to do this, but I just thought it was
something interesting.
If you're a virologist of the [xkcd](https://xkcd.com/350/) kind,
another helper command you might make is this:
```nushell
# Install any packages it finds
def live-dangerously [ ...pkgs ] {
# One optional argument was given (exclude), while another was not (repositories)
search-pkgs 0 [] ...$pkgs --install # Flags can go after spread arguments
}
```
Running it:
```nushell
> live-dangerously "git" "*vi*" # *vi* because I don't feel like typing out vim and neovim
╭──────────────┬─────────────╮
│ install │ true │
│ log_level │ 0 │
│ exclude │ [] │
│ repositories │ null │
│ pkgs │ [git, *vi*] │
╰──────────────┴─────────────╯
```
Here's an example that uses the spread operator more than once within
the same command call:
```nushell
let extras = [ chrome firefox python java git ]
def search-pkgs-curated [ ...pkgs ] {
(search-pkgs
1
[emacs]
["example.com", "foo.com"]
vim # A must for everyone!
...($pkgs | filter { |p| not ($p | str contains "*") }) # Remove packages with globs
python # Good tool to have
...$extras
--install=false
python3) # I forget, did I already put Python in extras?
}
```
Running it:
```nushell
> search-pkgs-curated "git" "*vi*"
╭──────────────┬───────────────────────────────────────────────────────────────────╮
│ install │ false │
│ log_level │ 1 │
│ exclude │ [emacs] │
│ repositories │ [example.com, foo.com] │
│ pkgs │ [vim, git, python, chrome, firefox, python, java, git, "python3"] │
╰──────────────┴───────────────────────────────────────────────────────────────────╯
```
# Description
`Expression::replace_in_variable` is only called in one place, and it is
called with `new_var_id` = `IN_VARIABLE_ID`. So, it ends up doing
nothing. E.g., adding `debug_assert_eq!(new_var_id, IN_VARIABLE_ID)` in
`replace_in_variable` does not trigger any panic.

# After Submitting
# Description
With #11386 we don't have any nushell-internal code directly accessing
the `vals` field of `Record`, so let's make it private so everyone in
the future uses the checked ways guaranteeing matching cols/vals.
The `cols` feel has to remain pub for now as `rename` still directly
mutates this field. See #11020 for challenges for this refactor.
# Plugin-Author-Facing Changes
This is a breaking change for outside plugins that relied on the `pub`
fields.
# Description
Simplifies `SIGQUIT` protection to a single `signal` ignore system call.
# User-Facing Changes
`SIGQUIT` is no longer blocked if nushell is in non-interactive mode
(signals should not be blocked in non-interactive mode).
Also a breaking API change for `nu_protocol`.
# Tests + Formatting
Should come after #11178 for testing.
# Description
While #11057 is merged, it's hard to tell the difference between
`--flag: bool` and `--flag`, and it makes user hard to read custom
commands' signature, and hard to use them correctly.
After discussion, I think we can deprecate `--flag: bool` usage, and
encourage using `--flag` instead.
# User-Facing Changes
The following code will raise warning message, but don't stop from
running.
```nushell

# Description
`Value::MatchPattern` implies that `MatchPattern`s are first-class
values. This PR removes this case, and commands must now instead use
`Expr::MatchPattern` to extract `MatchPattern`s just like how the
`match` command does using `Expr::MatchBlock`.
# User-Facing Changes
Breaking API change for `nu_protocol` crate.
# Description
Since there are plans to add more history commands, it seems sensible to
put them into their own module and category
https://github.com/nushell/nushell/pull/10440#issuecomment-1731408785
# User-Facing Changes
The history commands are in the category "History" rather than "Misc"
# Description
This PR addresses #11204 which points out that using a closure for the
replacement value with `update`, `insert`, or `upsert` does not work for
lists.
# User-Facing Changes
- Replacement closures should now work for lists in `upsert`, `insert`,
and `update`. E.g., `[0] | update 0 {|i| $i + 1 }` now gives `[1]`
instead of an unhelpful error.
- `[1 2] | insert 4 20` no longer works. Before, this would give `[1, 2,
null, null, 20]`, but now it gives an error. This was done to match the
intended behavior in `Value::insert_data_at_cell_path`, whereas the
behavior before was probably unintentional. Following
`Value::insert_data_at_cell_path`, inserting at the end of a list is
also fine, so the valid indices for `upsert` and `insert` are
`0..=length` just like `Vec::insert` or list inserts in other languages.
# Tests + Formatting
Added tests for `upsert`, `insert`, and `update`:
- Replacement closures for lists, list streams, records, and tables
- Other list stream tests
# Description

Goes towards implementing #10598, which asks for a spread operator in
lists, in records, and when calling commands (continuation of #11006,
which only implements it in lists)
# Description
This PR is for adding a spread operator that can be used when building
records. Additional functionality can be added later.
Changes:
- Previously, the `Expr::Record` variant held `(Expression, Expression)`
pairs. It now holds instances of an enum `RecordItem` (the name isn't
amazing) that allows either a key-value mapping or a spread operator.
- `...` will be treated as the spread operator when it appears before
`$`, `{`, or `(` inside records (no whitespace allowed in between) (not
implemented yet)
- The error message for duplicate columns now includes the column name
itself, because if two spread records are involved in such an error, you
can't tell which field was duplicated from the spans alone
`...` will still be treated as a normal string outside records, and even
in records, it is not treated as a spread operator when not followed
immediately by a `$`, `{`, or `(`.
# User-Facing Changes
Users will be able to use `...` when building records.
```
> let rec = { x: 1, ...{ a: 2 } }
> $rec
╭───┬───╮
│ x │ 1 │
│ a │ 2 │
╰───┴───╯
> { foo: bar, ...$rec, baz: blah }
╭─────┬──────╮
│ foo │ bar │
│ x │ 1 │
│ a │ 2 │
│ baz │ blah │
╰─────┴──────╯
```
If you want to update a field of a record, you'll have to use `merge`
instead:
```
> { ...$rec, x: 5 }
Error: nu:🐚:column_defined_twice
× Record field or table column used twice: x

# Description
Close: #10278
This pr introduces `o>>`, `e>>`, `o+e>>` to allow redirection to append
to a file.
Examples:
```nushell
echo abc o>> a.txt
echo abc o>> a.txt
cat asdf e>> a.txt
cat asdf e>> a.txt
cat asdf o+e>> a.txt
```
~~TODO:~~
~~1. currently internal commands with `o+e>` redirect to a variable is
broken: `let x = "a.txt"; echo abc o+e> $x`, not sure when it was
introduced...~~
~~2. redirect stdout and stderr with append mode doesn't supported yet:
`cat asdf o>>a.txt e>>b.ext`~~
~~For these 2 items, I'd like to fix them in different prs.~~
Already done in this pr
# Description
This PR enables a new feature that shows which externals are found in
your path via the syntax highlighter as you type.
This idea could use some improvement where it caches the items in your
path and on some trigger, expires that cache and creates a new on. Right
now, all it does is call the `which` crate on every character you type.
This could be problematic if you have hundreds of paths in your PATH or
if some of your paths in your Path point to extraordinarily slow file
systems. WSL pointing to Windows comes to mind. Either way, I've thrown
it up here for people to try and provide feedback. I think the novelty
of showing what is valid and what isn't is pretty cool. I believe
fish-shell also does this, IIRC.

# Description
Fixes: #10271
Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```
This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```
## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command
These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.
### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.
# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa

╭───┬───╮

```
BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error: × Can't make stderr redirection twice
╭─[entry #1:1:1]

╭─[entry #2:1:1]

· ╰── try to remove one

```
# Description
`ShellError::FlagNotFound` had a note that said it may be removable so
this PR removes it instead of updating it to named fields per #10700
I can't see this error being used since it was introduced with #4364. I
can't find why or where it was used before that date, though. There was
a large merge with that PR but I can't penetrate the secrets of git to
find out where its earlier history went.

# Description
Slightly refactors the cell path functions (`insert_data_at_cell_path`,
etc.) for `Value` to fix a few bugs and ensure consistent behavior.
Namely, case (in)sensitivity now applies to lazy records just like it
does for regular `Records`. Also, the insert behavior of `insert` and
`upsert` now match, alongside fixing a few related bugs described below.
Otherwise, a few places were changed to use the `Record` API.
# Tests
Added tests for two bugs:
- `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the
innermost record `c`.
- `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before
this PR, doesn't add the field `b: 2` to each row.
# Description
These make it easy to make a Span that covers an entire argument and the
span of all arguments in a Call.
Call::arguments_span() is useful for errors where a command may accept
arguments or the pipeline, but not both.
Argument::span() is useful for errors where an arguments is incompatible
with one or more other arguments.
In particular, I wish to use this to create an error for an
implementation of #9563 that either allows arguments to set limits:
```nushell
limits set RLIMIT_NOFILE --soft 255 --hard 1024
```
Or pipeline:
```nushell
{name: RLIMIT_NOFILE, soft: 255} | limits set
```
But not both:
```
❯ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5
Error: nu:🐚:incompatible_parameters
× Incompatible parameters.

# Description
This PR fixes a minor bug that prevented this command from running.
```nushell
table --list | each {|r| print ($r); print (ls | first 3 | table --theme $r)}
```
Here's the output now of the first few themes.
It prevented it from running because "default" wasn't a real table
theme. Now "default" is a synonym of rounded.
Also tweaked the error message when a bad theme name is provided.

# Description
Compatible with `Vec::truncate` and `indexmap::IndexMap::truncate`
Found useful in #10903 for `drop column`
# Tests + Formatting
Doctest with the relevant edge-cases
# Description
Add an extension trait `IgnoreCaseExt` to nu_utils which adds some case
insensitivity helpers, and use them throughout nu to improve the
handling of case insensitivity. Proper case folding is done via unicase,
which is already a dependency via mime_guess from nu-command.
In actuality a lot of code still does `to_lowercase`, because unicase
only provides immediate comparison and doesn't expose a `to_folded_case`
yet. And since we do a lot of `contains`/`starts_with`/`ends_with`, it's
not sufficient to just have `eq_ignore_case`. But if we get access in
the future, this makes us ready to use it with a change in one place.
Plus, it's clearer what the purpose is at the call site to call
`to_folded_case` instead of `to_lowercase` if it's exclusively for the
purpose of case insensitive comparison, even if it just does
`to_lowercase` still.
# User-Facing Changes
- Some commands that were supposed to be case insensitive remained only
insensitive to ASCII case (a-z), and now are case insensitive w.r.t.
non-ASCII characters as well.

# Description
Replaces the only usage of `Value::follow_cell_path_not_from_user_input`
with some `Record::get`s.
# User-Facing Changes
Breaking change for `nu-protocol`, since
`Value::follow_cell_path_not_from_user_input` was deleted.
Nushell now reports errors for when environment conversions are not
closures.
# Description
This is pretty complementary/orthogonal to @IanManske 's changes to
`Value` cellpath accessors in:
- #10925
- to a lesser extent #10926
## Steps
- Use `R.remove` in `Value.remove_data_at_cell_path`
- Pretty sound after #10875 (tests mentioned in commit message have been
removed by that)
- Update `did_you_mean` helper to use iterator
- Change `Value::columns` to return iterator
- This is not a place of honor
- Use `Record::get` in `Value::get_data_by_key`
# User-Facing Changes
None intentional, potential edge cases on duplicated columns could
change (considered undefined behavior)
# Tests + Formatting
(-)
Matches the general behavior of `Vec::drain` or
`indexmap::IndexMap::drain`:
- Drop the remaining elements (implementing the unstable `keep_rest()`
would not be compatible with something like `indexmap`)
- No `AsRef<[T]>` or `Drain::as_slice()` behavior as this would make
layout assumptions.
- `Drain: DoubleEndedIterator`
Found useful in #10903
# Description
Where appropriate, this PR replaces instances of
`Value::get_data_by_key` and `Value::follow_cell_path` with
`Record::get`. This avoids some unnecessary clones and simplifies the
code in some places.
# Description
Our config exists both as a `Config` struct for internal consumption and
as a `Value`. The latter is exposed through `$env.config` and can be
both set and read.
Thus we have a complex bug-prone mechanism, that reads a `Value` and
then tries to plug anything where the value is unrepresentable in
`Config` with the correct state from `Config`.
The parsing involves therefore mutation of the `Value` in a nested
`Record` structure. Previously this was wholy done manually, with
indices.
To enable deletion for example, things had to be iterated over from the
back. Also things were indexed in a bunch of places. This was hard to
read and an invitation for bugs.
With #10876 we can now use `Record::retain_mut` to traverse the records,
modify anything that needs fixing, and drop invalid fields.
# Parts:
- Error messages now consistently use the correct spans pointing to the
problematic value and the paths displayed in some messages are also
aligned with the keys used for lookup.
- Reconstruction of values has been fixed for:
- `table.padding`
- `buffer_editor`
- `hooks.command_not_found`
- `datetime_format` (partial solution)
- Fix validation of `table.padding` input so value is not set (and
underflows `usize` causing `table` to run forever with negative values)
- New proper types for settings. Fully validated enums instead of
strings:
- `config.edit_mode` -> `EditMode`
- Don't fall back to vi-mode on invalid string
- `config.table.mode` -> `TableMode`
- there is still a fall back to `rounded` if given an invalid
`TableMode` as argument to the `nu` binary
- `config.completions.algorithm` -> `CompletionAlgorithm`
- `config.error_style` -> `ErrorStyle`
- don't implicitly fall back to `fancy` when given an invalid value.
- This should also shrink the size of `Config` as instead of 4x24 bytes
those fields now need only 4x1 bytes in `Config`
- Completely removed macros relying on the scope of `Value::into_config`
so we can break it up into smaller parts in the future.
- Factored everything into smaller files with the types and helpers for
particular topics.
- `NuCursorShape` now explicitly expresses the `Inherit` setting.
conversion to option only happens at the interface to `reedline`
# Description
Changes the `captures` field in `Closure` from a `HashMap` to a `Vec`
and makes `Stack::captures_to_stack` take an owned `Vec` instead of a
borrowed `HashMap`.
This eliminates the conversion to a `Vec` inside `captures_to_stack` and
makes it possible to avoid clones altogether when using an owned
`Closure` (which is the case for most commands). Additionally, using a
`Vec` reduces the size of `Value` by 8 bytes (down to 72).
# User-Facing Changes
Breaking API change for `nu-protocol`.

This is easy to do with rust-analyzer, but I didn't want to just pump
these all out without feedback.

Consequences of #10841
This does not yet make the assumption that columns are always
duplicated. Follow the existing logic here
- Use saner record API in `nu-engine/src/eval.rs`
- Use checked record construction in `nu-engine/src/scope.rs`
- Use `values` iterator in `nu-engine/src/scope.rs`
- Use `columns` iterator in `nu_engine::get_columns()`
- Start using record API in `value/mod.rs`
- Use `.insert` in `eval_const.rs` Record code
- Record API for `eval_const.rs` table code

# Description
Pretty much all operations/commands in Nushell assume that the column
names/keys in a record and thus also in a table (which consists of a
list of records) are unique.
Access through a string-like cell path should refer to a single column
or key/value pair and our output through `table` will only show the last
mention of a repeated column name.
```nu
[[a a]; [1 2]]
╭─#─┬─a─╮
│ 0 │ 2 │
╰───┴───╯
```
While the record parsing already either errors with the
`ShellError::ColumnDefinedTwice` or silently overwrites the first
occurence with the second occurence, the table literal syntax `[[header
columns]; [val1 val2]]` currently still allowed the creation of tables
(and internally records with more than one entry with the same name.
This is not only confusing, but also breaks some assumptions around how
we can efficiently perform operations or in the past lead to outright
bugs (e.g. #8431 fixed by #8446).
This PR proposes to make this an error.
After this change another hole which allowed the construction of records
with non-unique column names will be plugged.
## Parts
- Fix `SE::ColumnDefinedTwice` error code
- Remove previous tests permitting duplicate columns
- Deny duplicate column in table literal eval
- Deny duplicate column in const eval
- Deny duplicate column in `from nuon`
# User-Facing Changes
`[[a a]; [1 2]]` will now return an error:
```
Error: nu:🐚:column_defined_twice

· ┬ ┬
· │ ╰── field redefined here
· ╰── field first defined here

```
this may under rare circumstances block code from evaluating.
Furthermore this makes some NUON files invalid if they previously
contained tables with repeated column names.
# Tests + Formatting
Added tests for each of the different evaluation paths that materialize
tables.
# Description
Changes `FromValue` to take owned `Value`s instead of borrowed `Value`s.

# Description
Reuses the existing `Closure` type in `Value::Closure`. This will help

# User-Facing Changes

# Description
While we have now a few ways to add items or iterate over the
collection, we don't have a way to cleanly remove items from `Record`.
This PR fixes that:
- Add `Record.remove()` to remove by key
- makes the assumption that keys are unique, so can not be used
universally, yet (see #10875 for an important example)
- Add naive `Record.retain()` for inplace removal
- This follows the two separate `retain`/`retain_mut` in the Rust std
library types, compared to the value-mutating `retain` in `indexmap`
- Add `Record.retain_mut()` for one-pass pruning

# Description
> Our `Record` looks like a map, quacks like a map, so let's treat it
with the API for a map
Implement common methods found on e.g. `std::collections::HashMap` or
the insertion-ordered [indexmap](https://docs.rs/indexmap).
This allows contributors to not have to worry about how to get to the
relevant items and not mess up the assumptions of a Nushell record.
## Record assumptions
- `cols` and `vals` are of equal length
- for all practical purposes, keys/columns should be unique
## End goal
The end goal of the upcoming series of PR's is to allow us to make
`cols` and `vals` private.
Then it would be possible to exchange the backing datastructure to best
fit the expected workload.
This could be statically (by finding the best balance) or dynamically by
using an `enum` of potential representations.
## Parts
- Add validating explicit part constructor
`Record::from_raw_cols_vals()`
- Add `Record.columns()` iterator
- Add `Record.values()` iterator
- Add consuming `Record.into_values()` iterator
- Add `Record.contains()` helper
- Add `Record.insert()` that respects existing keys
- Add key-based `.get()`/`.get_mut()` to `Record`
- Add `Record.get_index()` for index-based access
- Implement `Extend` for `Record` naively
- Use checked constructor in `record!` macro
- Add `Record.index_of()` to get index by key
# User-Facing Changes
None directly
# Developer facing changes
You don't have to roll your own record handling and can use a familiar
API
# Tests + Formatting
No explicit unit tests yet. Wouldn't be too tricky to validate core
properties directly.
Will be exercised by the following PRs using the new
methods/traits/iterators.
# Description
Use `record!` macro instead of defining two separate `vec!` for `cols`
and `vals` when appropriate.
This visually aligns the key with the value.
Further more you don't have to deal with the construction of `Record {
cols, vals }` so we can hide the implementation details in the future.
## State
Not covering all possible commands yet, also some tests/examples are
better expressed by creating cols and vals separately.
# User/Developer-Facing Changes
The examples and tests should read more natural. No relevant functional
change
# Bycatch
Where I noticed it I replaced usage of `Value` constructors with
`Span::test_data()` or `Span::unknown()` to the `Value::test_...`
constructors. This should make things more readable and also simplify
changes to the `Span` system in the future.

Fixes#10571, also potentially: #10364, #10211, #9558, #9310,
# Description
Changes processing of arguments to filesystem commands that are source
paths or globs.
Applies to `cp, cp-old, mv, rm, du` but not `ls` (because it uses a
different globbing interface) or `glob` (because it uses a different
globbing library).
The core of the change is to lookup the argument first as a file and
only glob if it is not. That way,
a path containing glob metacharacters can be referenced without glob
quoting, though it will have to be single quoted to avoid nushell
parsing.
Before: A file path that looks like a glob is not matched by the glob
specified as a (source) argument and takes some thinking about to
access. You might say the glob pattern shadows a file with the same
spelling.
```

```
Before_2: if file has glob metachars but isn't a valid pattern, user
gets a confusing error:
```
> touch 'a[b'
> cp 'a[b' dest
Error: × Pattern syntax error near position 30: invalid range pattern
╭─[entry #13:1:1]
1 │ cp 'a[b' dest
· ──┬──
· ╰── invalid pattern
╰────
```
After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.
```
> cp --verbose 'a[bc]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
> cp --verbose '[a][bc]d' dest

copied /home/bobhy/src/rust/work/r4/acd to /home/bobhy/src/rust/work/r4/dest/acd
```
After_2: file with glob metachars but invalid pattern just works.
(though Windows does not allow file name to contain `*`.).
```
> cp --verbose 'a[b' dest
copied /home/bobhy/src/rust/work/r4/a[b to /home/bobhy/src/rust/work/r4/dest/a[b
```
So, with this fix, a file shadows a glob pattern with the same spelling.
If you have such a file and really want to use the glob pattern, you
will have to glob quote some of the characters in the pattern. I think
that's less confusing to the user: if ls shows a file with a weird name,
s/he'll still be able to copy, rename or delete it.
# User-Facing Changes
Could break some existing scripts. If user happened to have a file with
a globbish name but was using a glob pattern with the same spelling, the
new version will process the file and not expand the glob.

This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.
In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.
# User-Facing Changes
This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.

Support keyboard enhancement protocol as implemented by Kitty console,

This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.
For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.
# User-Facing Changes
This adds `use_kitty_protocol` config which defaults to false. When set

Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.

code, this introduced a runaway edge case in const evaluation (#10212)

- Remove special const-eval error test

# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.
Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.
Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.

# Description
There are several cursor shape related issues #7151#9243#7271#8452#10169, you can't disable the cursor shape feature even if you comment
out the entire `cursor_shape` block in the config.nu, and even worse,
when nushell exits with an error, the cursor shape can't be restored,
that is annoying.
This PR provides an opportunity to disable setting the cursor shape.
# User-Facing Changes
If you use the default config.nu, nothing changes, but if you comment
out `cursor_shape` block or set them to `inherit`, related cursor shape
will not be set.

# Description
Apparently some strftime formats are already localized and when you
"double localize" them, they don't work. This PR fixes that so that %x
%X %r %c don't go through the localization step.
Example: %x %X
### Before
```nushell
❯ date now | format date "%x %X %p"
09/08/2023 08 AM
```
### After
```nushell
❯ date now | format date "%x %X %p"
09/08/23 08:09:14 AM
```
I started to make one format_datetime to rule them all but one returns a
string and one returns a value. If we convert to the string, we lose the
nice error messages. If we change to value, more code has to be changed
elsewhere. So, I decided to just leave two functions.

# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```
this PR changes the name of the "cell path" type from `cell path` to
`cell-path`
# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.
same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`
this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.

# Description
This PR adds the ability to have a `$nu.plugin-path` even when you
plugins are registered and it also should work with `nu -n --no-stdlib`.
### Before
It would give an error
```
│ plugin-path │ IOError("Could not get plugin signature location") │
```
### After
It returns the proper path, like this for me
```
│ plugin-path │ /Users/fdncred/Library/Application Support/nushell/plugin.nu │

# Description
As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.
Hoping to get a few more helping hands to finish this, as there are a
lot of commands to update :)

# Description
This PR adds a new config item, `error_style`. It will render errors in
a screen reader friendly mode when set to `"simple"`. This is done using
`miette`'s own `NarratableReportHandler`, which seamlessly replaces the
default one when needed.
Before:
```
Error: nu:🐚:external_command
× External command failed
╭─[entry #2:1:1]
1 │ doesnt exist
· ───┬──
· ╰── executable was not found
╰────
help: No such file or directory (os error 2)
```
After:
```
Error: External command failed
Diagnostic severity: error
Begin snippet for entry #4 starting at line 1, column 1
snippet line 1: doesnt exist
label at line 1, columns 1 to 6: executable was not found
diagnostic help: No such file or directory (os error 2)
diagnostic code: nu:🐚:external_command
```
## Things to be determined
- ~Review naming. `errors.style` is not _that_ consistent with the rest
of the code. Menus use a `style` record, but table rendering mode is set
via `mode`.~ As it's a single config, we're using `error_style` for now.
- Should this kind of setting be toggable with one single parameter?
`accessibility.no_decorations` or similar, which would adjust the style
of both errors and tables accordingly.
# User-Facing Changes
No changes by default, errors will be rendered differently if
`error_style` is set to `simple`.

There's a PR updating the docs over here
https://github.com/nushell/nushell.github.io/pull/1026
# Description
This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.
We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
```rust
record! {
"key1" => some_value,
"key2" => Value::string("text", span),
"key3" => Value::int(optional_int.unwrap_or(0), span),
"key4" => Value::bool(config.setting, span),
}
```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.
Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants
Should unblock https://github.com/nushell/nushell/pull/9678
### Example:
```nushell
module spam {
export module eggs {
export module bacon {
export const viking = 'eats'
}
}
}
use spam
print $spam.eggs.bacon.viking # prints 'eats'
use spam [eggs]
print $eggs.bacon.viking # prints 'eats'
use spam eggs bacon viking
print $viking # prints 'eats'
```
### Limitation 1:
Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ] # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ] # obviously wrong name for a constant, but doesn't work also for commands
```
Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]
print $bacon.viking # prints 'eats'
```
I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.
### Limitation 2:
`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".
But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.
# User-Facing Changes
Command category changed from `deprecated` to `removed`
Running tests locally from nushell with customizations (i.e.
$env.PROMPT_COMMAND etc) may lead to failing tests as that customization
leaks to the sandboxed nu itself.
Remove `FILE_PWD` from env
# Tests + Formatting
Tests are now passing locally without issue in my case
# Description
This PR does three related changes:
* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.
Combined, the above allow the user to see the script name in the help
output of scripts, like so:
NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.
# User-Facing Changes
One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

This PR should close#8036, #9028 (in the negative) and #9118.
Fix for #9118 is a bit pedantic. As reported, the issue is:
```

```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".
# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).
# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.
## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.
Scripts that depended on month or year time units on output will need to
be changed.
### Examples
```
> 365day
52wk 1day
## Used to be:
## 1yr
> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day │ 1 │
│ sign │ + │
╰──────┴────╯
## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week │ 56 │
│ day │ 6 │
│ hour │ 6 │
│ minute │ 7 │
│ second │ 8 │
│ millisecond │ 9 │
│ microsecond │ 10 │
│ nanosecond │ 11 │
│ sign │ + │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.
Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

# Description
This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.
This sets the default config value in both the Rust and the default
nushell config.
To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.
Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

# Description
This PR changes `Value::columns` to return a slice of columns instead of
cloning said columns. If the caller needs an owned copy, they can use
`slice::to_vec` or the like. This eliminates unnecessary Vec clones
(e.g., in `update cells`).

fix#9796
Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.
Created a bunch of tests.

Note:
This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.
PS: Haven't tested on a wrapped/expanded tables.

Reverts nushell/nushell#9796
This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).
A patch to play with.
Need to make a few tests after all.
The question is what shall be done with `table.mode = none`, as it has
no borders.
```nu
$env.config.table.move_header = true

Relative: #8248
After this pr, user can define const variable inside a module.
And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):
## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`
## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.
It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.
What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.
## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.
# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.
# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.
Simplifies the example testing a bit.
# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.
## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`
## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011
# User-Facing Changes
this should not change anything, just make sure the default behaviour of
Nushell and the `default_config.nu` are in sync.

# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).
Work for #8670
## description
this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
_ if $x starts-with 'nu' => {},
$x => {}
}
```
these work pretty much like rust's match guards, with few limitations:
1. multiple matches using the `|` are not (yet?) supported
```nushell
match $num {
0 | _ if (is-odd $num) => {},
_ => {}
}
```
2. blocks cannot be used as guards, (yet?)
```nushell
match $num {
$x if { $x ** $x == inf } => {},
_ => {}
}
```
## checklist
- [x] syntax
- [x] syntax highlighting[^1]
- [x] semantics
- [x] tests
- [x] clean up
[^1]: defered for another pr
# Description
This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.
This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.
# User-Facing Changes

This work enforces many more checks on pipeline type correctness than
previous nushell versions. This strictness may uncover incompatibilities

# Description
This PR removes the compile-time overload system. Unfortunately, this
system never worked correctly because in a gradual type system where
types can be `Any`, you don't have enough information to correctly
resolve function calls with overloads. These resolutions must be done at
runtime, if they're supported.
That said, there's a bit of work that needs to go into resolving
input/output types (here overloads do not execute separate commands, but
the same command and each overload explains how each output type
corresponds to input types).
This PR also removes the type scope, which would give incorrect answers
in cases where multiple subexpressions were used in a pipeline.
# User-Facing Changes
Finishes removing compile-time overloads. These were only used in a few
places in the code base, but it's possible it may impact user code. I'll
mark this as breaking change so we can review.

# User-Facing Changes
**[BREAKING CHANGE]**
this change adds a field to `SyntaxShape::Table` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the table expects, `SyntaxShape::Table(vec![])` will
suffice
# Description
the current subtyping rule needs you to define the record entries in the
same order as declared in the annotation. this pr improves that
now
```nushell
{ name: 'Him', age: 12 }
# ,
{ age: 100, name: 'It' }
# and
{ name: 'Red', age: 69, height: "5-8" }
# will all match
record<name: string, age: int>
# previously only the first one would match
```
however, something like
```nushell
{ name: 'Her' } # will not
# and
{ name: 'Car', wheels: 5 }
```
EDIT: applied JT's suggestion
# Description
We previously simply searched all commands in the working set. As our
deprecated/removed subcommands are documented by stub commands that
don't do anything apart from providing a message, they were still
included.
With this change we check the `Signature.category` to not be
`Category::Deprecated`.
## Note on performance
Making this change will exercise `Command.signature()` more
frequently! As the rust-implemented commands include their builders here
this probably will cause a number of extra allocations. There is
actually no valid reason why the commands should construct a new
`Signature` for each call to `Command.signature()`.
This will introduce some overhead to generate the completions for
commands.

# Description
For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.
So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.
Before:
```
let-env FOO = "BAR"
```
Now:
```
$env.FOO = "BAR"
```
It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

# Description
This PR does a few things to help improve type hovers and, in the
process, fixes a few outstanding issues in the type system. Here's a
list of the changes:
* `for` now will try to infer the type of the iteration variable based
on the expression it's given. This fixes things like `for x in [1, 2, 3]
{ }` where `x` now properly gets the int type.
* Removed old input/output type fields from the signature, focuses on
the vec of signatures. Updated a bunch of dataframe commands that hadn't
moved over. This helps tie things together a bit better
* Fixed inference of types from subexpressions to use the last
expression in the block
* Fixed handling of explicit types in `let` and `mut` calls, so we now
respect that as the authoritative type
I also tried to add `def` input/output type inference, but unfortunately
we only know the predecl types universally, which means we won't have
enough information to properly know what the types of the custom
commands are.
# User-Facing Changes
Script typechecking will get tighter in some cases
Hovers should be more accurate in some cases that previously resorted to
any.

# Description
`chrono::Datetime::to_rfc2822()` panics when it would format a negative
year. 3339 does not. This makes negative-year datetimes inconsistent
compared to positive ones, but it's better than a panic.
# Description
`derive(EnumIter)` is only required to run completeness tests.
Thus make the derive conditional on test and move `strum` and
`strum_macros` to the dev dependencies.
## Is it worth it?
Removing this derive does not change the binary size (checked via `cargo
bloat --crates` from `cargo-bloat`).
Compile time change is below a second so hard to judge based on a single
run of `cargo clean --profile dev; cargo build --timings`
Unsure if this negatively impacts how incremental compilation can
recompile when you switch between `cargo build`/`run` and `cargo test`
in your local workflow.
To get rid of `strum`/`strum_macros` as a proc macro crate we would need
to also remove it from `reedline`.
Further more a crate in the `polars` dependency tree uses `strum`
(curently not as relevant for the 1.0 build).
# Description
This PR improves the error message if an environment variable (that's
visible before the parser begins) is used in the form of `$PATH` instead
of `$env.PATH`.

```

- improves usability of datetime's in displayed text
-
# Description
Creates a config point for specifying long / short date time formats.
Defaults to humanized as we have today.
Provides for adding strftime formats into config.nu such as:
```nu
datetime_format: {
normal: "%Y-%m-%d %H:%M:%S"
table: "%Y-%m-%d"
}
```
Example:
```bash
> $env.config.datetime_format
┏━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ normal ┃ %a, %d %b %Y %H:%M:%S %z ┃
┃ table ┃ %m/%d/%y %I:%M:%S%p ┃
┗━━━━━━━━┻━━━━━━━━━━━━━━━━━━━━━━━━━━┛
> let a = (date now)
> echo $a
Thu, 22 Jun 2023 10:21:23 -0700
> echo [$a]
┏━━━┳━━━━━━━━━━━━━━━━━━━━━┓
┃ 0 ┃ 06/22/23 10:21:23AM ┃
┗━━━┻━━━━━━━━━━━━━━━━━━━━━┛
```
# User-Facing Changes
Any place converting a datetime to a user displayed value should be
impacted.

# Description
This PR cleans up the deprecated legacy config options that were
deprecated in nushell version 0.72.0. These are the config points that
were in the root of the config but also duplicated in the nested
structures. For instance `use_ls_colors` was in the root of the config
and also in the `ls.use_ls_colors` nested structure. This was originally
done to preserve backwards compatibility when nested structures were
introduced in the config file.
Here's a list of the legacy config points that were removed.
- `use_ls_colors` - previously replaced with `ls.use_ls_colors`
- `rm_always_trash` - previously replaced with `rm.always_trash`
- `history_file_format` - previously replaced with `history.file_format`
- `sync_history_on_enter` - previously replaced with
`history.sync_on_enter`
- `max_history_size` - previously replaced with `history.max_size`
- `quick_completions` - previously replaced with `completions.quick`
- `partial_completions` - previously replaced with `completions.partial`
- `max_external_completion_results` - previously replaced with
`completions.external.max_results`
- `completion_algorithm` - previously replaced with
`completions.algorithm`
- `case_sensitive_completions` - previously replaced with
`completions.case_sensitive`
- `enable_external_completion` - previously replaced with
`completions.external.enable`
- `external_completer` - previously replaced with
`completions.external.completer`
- `table_mode` - previously replaced with `table.mode`
- `table_index_mode` - previously replaced with `table.index_mode`
- `table_trim` - previously replaced with `table.trim`
- `show_clickable_links_in_ls` - previously replaced with
`ls.clickable_links`
- `cd_with_abbreviations` - previously replaced with `cd.abbreviations`
- `filesize_metric` - previously replaced with `filesize.metric`
- `filesize_format` - previously replaced with `filesize.format`
- `cursor_shape_vi_insert` - previously replaced with
`cursor_shape.vi_insert`
- `cursor_shape_vi_normal` - previously replaced with
`cursor_shape.vi_normal`
- `cursor_shape_emacs` - previously replaced with `cursor_shape.emacs`
Removes log_level from the config since it doesn't do anything any
longer. We moved log-level to a nushell parameter some time ago.
Renames history_isolation to isolation in the config.nu for consistency.
Fixes a couple bugs where values weren't being set in the "//
Reconstruct" sections (history_isolation, table_show_empty).
Reorganized/Moved things around a tiny bit and added a few comments.
# User-Facing Changes
history.histor_isolation is now history.isolation.
If anyone is still using the legacy config points, deprecated since
0.72.0 2022-11-29, their config will break.

In my view we should revert nushell/nushell#8395 for now
## Potentially inconsistent application of semantic change
#8395 (1d5e7b441b) was loosening the type
coercion rules significantly, to let missing data / void returns that
were either expressed by `PipelineData::Empty` or the `Value::nothing`
be accept by specifically those commands/operations that made use of
`PipelineData::into_iter_strict()`. This could apply the new rules
inconsistently.
## Turning explicit failures into silent continuations
Furthermore the effect of this breaking change to the missing data
semantics could make previous errors into silent failures.
This could either just reduce the effectiveness of teaching error
messages in interactive use:
### Contrived example before
```bash
> cd . | where blah
Error: nu:🐚:only_supports_this_input_type
× Input type not supported.
╭─[entry #13:1:1]
1 │ cd . | where blah
· ──┬──┬
· │ ╰── input type: null
· ╰── only list, binary, raw data or range input data is supported
╰────
```
### ...after, with #8395
```bash
> cd . | where blah
╭────────────╮
│ empty list │
╰────────────╯
```
In rare cases people could already try to rely on catching an error of a
downstream command to actually deal with the missing data, so it would
be a breaking change for their existing code.
## Problem with `PipelineData::into_iter_strict()`
Maybe this makes `_strict` a bit of a misnomer for this particular
iterator construction.
Further we did not actively test the `PipelineData::empty` branch before
## Parsimonious solution exists
For the motivating issue https://github.com/nushell/nushell/issues/8393
there already exists a fix that makes `ls` more consistent with the type
system by returning an empty `Value::List`
https://github.com/nushell/nushell/pull/8439
# Description
This allows empty pipelines to pass their emptiness through a filter.
This helps fix issues like trying to run a filter on an `ls` in an empty
directory. It also feels a bit more reasonable that a filter filters
what is *there* but doesn't require something to be there.
fixes#8393
# User-Facing Changes
No breaking changes (that I know of). Should allow filtering to be a
little less surprising with emptiness.

# Description
Fixes a small bug with `rm` where names of files which couldn't be
deleted due to error were not printed.
Fixes https://github.com/nushell/nushell/issues/9004
# User-Facing Changes
Slightly different error message than previously. Nothing significant,
though.
The new error message looks like this
```
~/Projects/rust/nushell> rm /proc/1/mem 05/06/2023 01:13:23 PM
Error: nu:🐚:remove_not_possible
× Remove not possible
╭─[entry #3:1:1]
1 │ rm /proc/1/mem
· ─────┬─────
· ╰── Could not delete /proc/1/mem: Operation not permitted (os error 1)
╰────
```
or when using a glob (only showing a single entry for brevity)
```
Error: nu:🐚:remove_not_possible
× Remove not possible
╭─[entry #2:1:1]
1 │ rm --recursive --force --verbose /proc/1/*
· ────┬────
· ╰── Could not delete /proc/1/comm: Operation not permitted (os error 1)
╰────
```
# Tests + Formatting
No new unit tests were added for this change as it is pretty difficult
to test this particular case. However, manual testing was run with the
following commands
```
rm /proc/1/mem
rm --recursive --force --verbose /proc/1/*
```
# After Submitting
N/A
This PR reverts https://github.com/nushell/nushell/pull/9391
We try not to revert PRs like this, though after discussion with the
Nushell team, we decided to revert this one.
The main reason is that Nushell, as a codebase, isn't ready for these
kinds of optimisations. It's in the part of the development cycle where
our main focus should be on improving the algorithms inside of Nushell
itself. Once we have matured our algorithms, then we can look for
opportunities to switch out technologies we're using for alternate
forms.
Much of Nushell still has lots of opportunities for tuning the codebase,
paying down technical debt, and making the codebase generally cleaner
and more robust. This should be the focus. Performance improvements
should flow out of that work.
Said another, optimisation that isn't part of tuning the codebase is
premature at this stage. We need to focus on doing the hard work of
making the engine, parser, etc better.

# Description
This removes some unnecessary SyntaxShapes when parsing a
SyntaxShape::Any. Recent updates to the parser look for `{` and then
handle the logic for that separately.
# User-Facing Changes
This may have a slight parser speedup.

# Description
Despite the innocent-looking title, this PR involves quite a few backend
changes as the existing LazyRecord trait was not at all friendly towards
the idea of these values being generated on the fly from Nu code.
In particular, here are a few changes involved:
- The LazyRecord trait now involves a lifetime `'a`, and this lifetime
is used in the return value of `get_column_names`. This means it no
longer returns `'static str`s (but implementations still can return
these). This is more stringent on the consumption side.
- The LazyRecord trait now must be able to clone itself via a new
`clone_value` method (as requiring `Clone` is not object safe). This
pattern is borrowed from `Value::CustomValue`.
- LazyRecord no longer requires being serde serializable and
deserializable.
These, in hand, allow for the following:
- LazyRecord can now clone itself, which means that they don't have to
be collected into a Record when being cloned.
- This is especially useful in Stack, which is cloned on each repl line
and in a few other cases. This would mean that _every_ LazyRecord
instance stored in a variable would be collected in its entirety and
cloned, which can be catastrophic for performance. See: `let nulol =
$nu`.
- LazyRecord's columns don't have to be static, they can have the same
lifetime of the struct itself, so different instances of the same
LazyRecord type can have different columns and values (like the new
`NuLazyRecord`)
- Serialization and deserialization are no longer meaningless, they are
simply less.
I would consider this PR very "drafty", but everything works. It
probably requires some cleanup and testing, though, but I'd like some
eyes and pointers first.
# User-Facing Changes
New command. New restrictions are largely internal. Maybe there are some
plugins affected?
Example of new command's usage:
```
lazy make --columns [a b c] --get-value { |name| print $"getting ($name)"; $name | str upcase }
```
You can also trivially implement something like `lazy make record` to
take a record of closures and turn it into a getter-like lazy struct:
```
def "lazy make record" [
record: record
] {
let columns = ($record | columns)
lazy make --columns $columns --get-value { |col| do ($record | get $col) }
}
```
Open to bikeshedding. `lazy make` is similar to `error make` which is
also in the core commands. I didn't like `make lazy` since it sounded
like some transformation was going on.
# Tour for reviewers
Take a look at LazyMake's examples. They have `None` as the results, as
such they aren't _really_ correct and aren't being tested at all. I
didn't do this because creating the Value::LazyRecord is a little tricky
and didn't want to risk messing it up, especially as the necessary
variables aren't available when creating the examples (like stack and
engine state).
Also take a look at NuLazyRecord's get_value implementation, or in
general. It uses an Arc<Mutex<_>> for the stack, which must be accessed
mutably for eval_block but get_value only provides us with a `&self`.
This is a sad state of affairs, but I don't know if there's a better
way.
On the same code path, we also have pipeline handling, and any pipeline
that isn't a Pipeline::Value will return Value::nothing. I believe
returning a Value::Error is probably better, or maybe some other
handling. Couldn't decide on which ShellError to settle with for that
branch.
The "unfortunate casualty" in the columns.rs file. I'm not sure just how
bad that is, though, I simply had to fight a little with the borrow
checker.
A few leftover comments like derives, comments about the now
non-existing serde requirements, and impls. I'll definitely get around
to those eventually but they're in atm
Should NuLazyRecord implement caching? I'm leaning heavily towards
**yes**, this was one of the main reasons not to use a record of
closures (besides convenience), but maybe it could be opt-out. I'd
wonder about its implementation too, but a simple way would be to move a
HashMap into the mutex state and keep cached values there.
# Description
Fixes: #8565
Here is another pr #7240 tried to address the issue, but it works in a
wrong way.
After this change `o+e>` won't redirect all stdout message then stderr
message and it works more like how bash does.
# User-Facing Changes
For the given python code:
```python
# test.py
import sys
print('aa'*300, flush=True)
print('bb'*999999, file=sys.stderr, flush=True)
print('cc'*300, flush=True)
```
Running `python test.py out+err> a.txt` shoudn't hang nushell, and
`a.txt` keeps output in the same order
## About the change
The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SameTargetRedirection` if we meet `out+err>` redirection
token(which is generated by lex function),
During converting from lite block to block,
LiteElement::SameTargetRedirection will be converted to
PipelineElement::SameTargetRedirection.
Then in the block eval process, if we get
PipelineElement::SameTargetRedirection, we'll invoke `run-external` with
`--redirect-combine` flag, then pipe the result into save command
## What happened internally?
Take the following command as example:
`^ls o+e> log.txt`
lex parsing result(`Tokens`) are not changed, but `LiteBlock` and
`Block` is changed after this pr.
### LiteBlock before
```rust
LiteBlock {
block: [
LitePipeline { commands: [
Command(None, LiteCommand { comments: [], parts: [Span { start: 39041, end: 39044 }] }),
// actually the span of first Redirection is wrong too..
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
]
}]
}
```
### LiteBlock after
```rust
LiteBlock {
block: [
LitePipeline {
commands: [
SameTargetRedirection {
cmd: (None, LiteCommand { comments: [], parts: [Span { start: 147945, end: 147948}]}),
redirection: (Span { start: 147949, end: 147957 }, LiteCommand { comments: [], parts: [Span { start: 147958, end: 147965 }]})
}
]
}
]
}
```
### Block before
```rust
Pipeline {
elements: [
Expression(None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),
span: Span { start: 39041, end: 39044 },
ty: Any, custom_completion: None
}),
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None })] }
```
### Block after
```rust
Pipeline {
elements: [
SameTargetRedirection {
cmd: (None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 147946, end: 147948 }, ty: String, custom_completion: None}, [], false),
span: Span { start: 147945, end: 147948},
ty: Any, custom_completion: None
}),
redirection: (Span { start: 147949, end: 147957}, Expression {expr: String("log.txt"), span: Span { start: 147958, end: 147965 },ty: String,custom_completion: None}
}

Show parameter defaults in scope command signature, where they're
available for display by help.
per https://github.com/nushell/nushell/issues/8928.
I found unexpected ramifications in one completer (NuHelpCompleter) and
plugins, which both use the flag-formatting routine from builtin help.
For the moment I made the minimum necessary changes to get the mainline
scenario to pass tests and run. But we should circle back on what to do
with plugins and help completer..
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
1. New `parameter_default` column to `signatures` table in
`$nu.scope.commands`
It is populated with whatever parameters can be defaulted: currently
positional args and named flags.
2. Built in help (both `help <command>` and `<command> --help` will
display the defaults
3. Help completer will display defaults for flags, but not for
positionals.
Example:
A custom command with some default parameters:
```
〉cat ~/work/dflts.nu
# sample function to show defaults in help
export def main [
arg1: string # mandatory positional
arg2:string=abc # optional positional
--switch # no default here
--named:int # named flag, no default
--other:string=def # flag
--hard:record<foo:int bar:string, bas:bool> # default can be compound type
= {foo:22, bar:"other worlds", bas:false}
] { {arg1: $arg1,
arg2: $arg2,
switch: $switch,
named: $named,
other: $other,
hard: $hard, }
}
〉use ~/work/dflts.nu

# Description
Follow-up of #8940. As @bobhy pointed out, it makes sense for the
behaviour of flags to match the one for positional arguments, where
default values are of type `Option<Value>` instead of
`Option<Expression>`.
# User-Facing Changes
The same ones from the original PR:
- Flag default values will now be parsed as constants.
- If the default value is not a constant, a parser error is displayed.
# Tests + Formatting
A [new
test](e34e2d35f4/src/tests/test_engine.rs (L338-L344))
has been added to verify the new restriction.
# Description
This PR impacts the nushell sqlite history only.
This is the first PR that enables history isolation in nushell for the
sqlite history. Hopefully, we can continue building on this.
This PR allows "history isolation" which means that other nushell
session's history won't be available in the current session when using
the uparrow/downarrow history navigation. This change only impacts the
uparrow downarrow history navigation.
What remains to be done is making ctrl+r history menu respect this
setting too. Right now, the history menu will still show you all entries
from all sessions.
The history command also shows all history items from all sessions. This
may remain unchanged since you can just filter by history session right
now.
This also fixes a bug where the session id is 0 in the sqlite history
since my April 18th reedline PR.

# Description
follow up to #8529
cleaned up version of #8892
- the original syntax is okay
```nu
def okay [rec: record] {}
```
- you can now add type annotations for fields if you know
them before hand
```nu
def okay [rec: record<name: string>] {}
```
- you can specify multiple fields
```nu
def okay [person: record<name: string age: int>] {}
# an optional comma is allowed
def okay [person: record<name: string, age: int>] {}
```
- if annotations are specified, any use of the command will be type
checked against the specified type
```nu
def unwrap [result: record<ok: bool, value: any>] {}
unwrap {ok: 2, value: "value"}
# errors with
Error: nu::parser::type_mismatch
× Type mismatch.

╰────
```
> here the error is in the `ok` field, since `any` is coerced into any
type
> as a result `unwrap {ok: true, value: "value"}` is okay
- the key must be a string, either quoted or unquoted
```nu
def err [rec: record<{}: list>] {}

```
- a key doesn't have to have a type in which case it is assumed to be
`any`
```nu
def okay [person: record<name age>] {}
def okay [person: record<name: string age>] {}
```
- however, if you put a colon, you have to specify a type
```nu
def err [person: record<name: >] {}
# errors with
Error: nu::parser::parse_mismatch
× Parse mismatch during operation.
╭─[entry #12:1:1]

# User-Facing Changes
**[BREAKING CHANGES]**
- this change adds a field to `SyntaxShape::Record` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the record expects, `SyntaxShape::Record(vec![])`
will suffice
# Description
This PR changes the `ast` command to be able to output `--json` as well
as `nuon` (default) with "pretty" and "minified" output. I'm hoping this
functionality will be usable in the vscode extension for semantic
tokenization and highlighting.
# User-Facing Changes
There's a new `--json`/`-j` option. Prior version output of nuon is
maintained as default.

# Description
Close: #8988
Thanks to new crossterm version, nushell can support blink cursor shape.
It can be config with the following value:
1. blink_block
2. blink_line
3. blink_underscore
And original block, line, underscore will be steady. It also fixes wrong
shape of `underscore`.
# User-Facing Changes
Here is a little breaking change, before the change: `line` cursor shape
is blinking line, but after this pr, it will be `steady line`. To make a
blink line, we need to change the value to `blink_line`.
But I think it's ok, because after the change, we have a good naming
convention about the name of shape

# Description
This does a lookup in the cache of parsed files to see if a span can be
found for a file that was previously loaded with the same contents, then
uses that span to find the parsed block for that file. The end result
should, in theory, be identical but doesn't require any reparsing or
creating new blocks/new definitions that aren't needed.
This drops the sg.nu benchmark from:

I was hoping to also see some startup time improvements, but I didn't
notice much there.

# Description
this pr condenses `MutBuiltinVar`, `LetBuiltinVar` and `ConstBuiltinVar`
into one error:
```nu
Error: nu::parser::name_is_builtin_var
× `in` used as variable name.
╭─[entry #69:1:1]
1 │ let in = 420
· ─┬
· ╰── already a builtin variable
╰────
help: 'in' is the name of a builtin Nushell variable and cannot be used
as a variable name
```
it also fixes this case which was previously not handled
```nu
let $nu = 420 # this variable would have been 'lost'
```
# Description
Trying a few different things to hopefully speedup startup a bit. I'm
seeing some improvement on my box for the profiles I have, but the data
I'm seeing is noisy.
- Remove allocations in a few places where we created vec's but could
use iterators
- Pre-allocate space for blocks based on the lite block
- Removed a few extra clones
