# Description
Update a few defaults.
1. use_ls_colors_completeions defaults to true.
2. make ide_menu only offer 10 completions at a time with
`max_completion_height = 10` instead of taking the entire screen.

# 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

╭─[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]
1 │ use $"($file)"
· ─────┬────
· ╰── module foo.nu not found
╰────
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

/home/windsoilder/a
> def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a')
/home/windsoilder/a
/home/windsoilder/a
```
#### After
```nushell

# 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

2. Change some commands which accept an input type, but generates

relative output type to `<any>`
Yeah it makes some commands more permissive, but I think it's better to

# 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.

# 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
Replace `.to_string()` used in `GenericError` with `.into()` as

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}

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

Error: × Can't make stderr redirection twice

```
# 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.

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
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.

# 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).

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

- Replaced `start`/`end` with span.
- Fixed standard library.
- Add `help` option.
- Add a couple more errors for invalid record types.
Resolve#10914
# Description
# User-Facing Changes
- **BREAKING CHANGE:** `error make` now takes in `span` instead of
`start`/`end`:
```Nushell
error make {
msg: "Message"
label: {
text: "Label text"
span: (metadata $var).span
}
}
```
- `error make` now has a `help` argument for custom error help.
# Description
Replaces the `Vec::remove` in `Record::retain_mut` with some swaps which
should eliminate the `O(n^2)` complexity due to repeated shifting of
elements.
# Description
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
× Record field or table column used twice
╭─[entry #2:1:1]
1 │ [[a a]; [1 2]]
· ┬ ┬
· │ ╰── 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.
This eliminates some unnecessary clones (e.g., in `call_ext.rs`).
# User-Facing Changes
Breaking API change for `nu_protocol`.
# Description
Reuses the existing `Closure` type in `Value::Closure`. This will help
with the span refactoring for `Value`. Additionally, this allows us to
more easily box or unbox the `Closure` case should we chose to do so in
the future.
# User-Facing Changes
Breaking API change for `nu_protocol`.
# Description
These macros simply took a `Span` and a shared reference to `Config` and
returned a Value, for better readability and reasoning about their
behavior convert them to simple function as they don't do anything
relevant with their macro powers.
