# Description
Now we can use `nu --testbin cococo` instead of `^echo` to echo messages
to stdout in tests.
But `nu` treats parameters as its own flags when parameter starts with
`-`. So `^echo --foo='bar'` still use `^echo`.

Finishes implementing https://github.com/nushell/nushell/issues/10598,
which asks for a spread operator in lists, in records, and when calling
commands.

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:
![image](https://github.com/nushell/nushell/assets/45539777/93faceae-00eb-4e59-ac3f-17f98436e6e4)
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"] │
╰──────────────┴───────────────────────────────────────────────────────────────────╯
```
Intends to close#8920
This PR suggests a new flag for the `http` commands, `--redirect-mode`,
which enables users to choose between different redirect handling modes.
The current behaviour of letting ureq silently follow redirects remains
the default, but two new options are introduced here, following the lead
of [JavaScript's `fetch`
API](https://developer.mozilla.org/en-US/docs/Web/API/fetch#redirect):
"manual", where any 3xx response to a request is simply returned as the
command's result, and "error", where any 3xx response causes a network
error like those caused by 4xx and 5xx responses.
This PR is a draft. Tests have not been added or run, the flag is
currently only implemented for the `http get` command, and design tweaks
are likely to be appropriate.
Most notably, it's not obvious to me whether a single flag which can
take one of three values is the nicest solution here.
We might instead consider two binary flags (like
`--no-following-redirects` and `--disallow-redirects`, although I'm bad
at naming things so I need help with that anyway), or completely drop
the "error" option if it's not deemed useful enough. (I personally think
it has some merit, especially since 4xx and 5xx responses are already
treated as errors by default; So this would allow users to treat only
immediate 2xx responses as success)
# User-facing changes
New options for the `http [method]` commands. Behaviour remains
unchanged when the command line flag introduced here is not used.

When running `cargo test --workspace` a file `crates/nu-command/a.txt`
remained which we also saw as an accidential additions in some commits.
Searching for `a.txt` narrowed it down that
`redirection_keep_exit_codes` was not sandboxed in a temporary directory
and created this file.
Went through redirection tests and placed them in a `Playground` to get
sandboxing `dirs` for `nu!(cwd:`.
For those tests where redirection fails and no file should be created
now I added a check that no file is created on accident.
- Sandbox `redirection_keep_exit_codes` test
- Sandbox `no_duplicate_redirection` test
- Check that no redirect file is created on error

# 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

exists with non-zero exit code.

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.~~

This PR addresses issue with cp brough up on

where target of cp is not correctly expanded.
If one has directory `test` with file `file.txt` in it then the
following command (in one line or inside a `do` block):
```nu
cd test; let file = 'copy.txt'; cp file.txt $file
```
will create a `copy.txt` in `.` not in `test` instead. This happens
because target of `cp` is a variable which is not expanded unlike a
string literal

# 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
cc
```
## After
```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
❯ echo a e> a.txt e> a.txt
Error: × Can't make stderr redirection twice

# Description
I'm not sure if "is-terminal" is the best name for this command as there
is also "term size". Uses
[`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal)
which is cross-platform.
Possible alternative names:
* `term is-tty --stdout`
* `term is-tty stdout`
* `term is-terminal stdout`
If multiple streams are provided an error is returned. The error span
covers all arguments as the incompatible one is not known. This may be
new?
Fixes#10517
# User-Facing Changes

# 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.
closes#10845
I've opened this a little prematurely to get some questions answered
before I cleanup the code.
As I started trying to better understand GNUs `mktemp` I've realized its
kind of peculiar and we might want to change its behavior to introduce
it to nushell.
#### quiet and dry run
Does it make sense to keep the `quiet` and `dry_run` flags? I don't
think so. The GNU documentation says this about the dry run flag "Using
the output of this command to create a new file is inherently unsafe, as
there is a window of time between generating the name and using it where
another process can create an object by the same name." So yeah why keep
it? As far as quiet goes, does it make sense to silence the errors in
nushell?
#### other confusing flags
According to the [gnu
docs](https://www.gnu.org/software/coreutils/manual/html_node/mktemp-invocation.html),
the `-t` flag is deprecated and the `-p`/ `--tempdir` are the same flag
with the only difference being `--tempdir` takes an optional path, Given
that, I've broken the `-p` away from `--tempdir`. Now there is one
switch `--tmpdir`/`-t` and one named param `--tmpdir-path`/`-p`.
GNU mktemp
```
-p DIR, --tmpdir[=DIR] interpret TEMPLATE relative to DIR; if DIR is not
specified, use $TMPDIR if set, else /tmp. With
this option, TEMPLATE must not be an absolute name;
unlike with -t, TEMPLATE may contain slashes, but
mktemp creates only the final component
-t interpret TEMPLATE as a single file name component,
relative to a directory: $TMPDIR, if set; else the
directory specified via -p; else /tmp [deprecated]
```
to
nushell mktemp
```
-p, --tmpdir-path <Filepath> # named param, must provide a path
-t, --tmpdir # a switch
```
Is this a terrible idea?
What should I do?

# Description
This PR refactors `drop columns` and fixes issues #10902 and #6846.
Tables with "holes" are now handled consistently, although still
somewhat awkwardly. That is, the columns in the first row are used to
determine which columns to drop, meaning that the columns displayed all
the way to the right by `table` may not be the columns actually being
dropped. For example, `[{a: 1}, {b: 2}] | drop column` will drop column
`a` instead of `b`. Before, this would give a list of empty records.
# User-Facing Changes
`drop columns` can now take records as input.
# Description
Based of the work and discussion in #10844, this PR adds the `exec`
command for Windows. This is done by simply spawning a
`std::process::Command` and then immediately exiting via
`std::process::exit` once the child process is finished. The child
process's exit code is passed to `exit`.
# User-Facing Changes
The `exec` command is now available on Windows, and there should be no
change in behaviour for Unix systems.
# Description
`split-by` only works on a `Record`, the error type was updated to
match, and now uses a more-specific type. (Two type fixes for the price
of one!)
The `usage` was updated to say "record" as well
# User-Facing Changes
* Providing the wrong type to `split-by` now gives an error messages
with the correct required input type

msg: "Message"
label: {
text: "Label text"
span: (metadata $var).span
}
}
```
- `error make` now has a `help` argument for custom error help.
# 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
as we can see in the [documentation of
`str.to_lowercase`](https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase),
not only ASCII symbols have lower and upper variants.
- `str upcase` uses the correct method to convert the string
7ac5a01e2f/crates/nu-command/src/strings/str_/case/upcase.rs (L93)
- `str downcase` incorrectly converts only ASCII characters
7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124)
this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in
`str downcase`.

# After Submitting
# Description
Currently the following command is broken:
```nushell
echo a o+e> 1.txt
```
It's because we don't redirect output of `echo` command. This pr is
trying to fix it.
# Description
- this PR should close#10819
# User-Facing Changes
Behaviour is similar to pre 0.86.0 behaviour of the cp command and
should as such not have a user-facing change, only compared to the
current version, were the option is readded.
# After Submitting
I guess the documentation will be automatically updated and as this
feature is no further highlighted, probably, no more work will be needed
here.
# Considerations
coreutils actually allows a third option:
```
pub enum UpdateMode {
// --update=`all`,
ReplaceAll,
// --update=`none`
ReplaceNone,
// --update=`older`
// -u
ReplaceIfOlder,
}
```
namely `ReplaceNone`, which I have not added. Also I think that
specifying `--update 'abc'` is non functional.
# Description
Fixes: #10830
The issue happened during lite-parsing, when we want to put a
`LiteElement` to a `LitePipeline`, we do nothing if relative redirection
target is empty.
So the command `echo aaa o> | ignore` will be interpreted to `echo aaa |
ignore`.
This pr is going to check and return an error if redirection target is
empty.
# User-Facing Changes

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Users can pattern match against a `null` literal.
# Description
`from tsv` and `from csv` both support a `--flexible` flag. This flag
can be used to "allow the number of fields in records to be variable".
Previously, a record's invariant that `rec.cols.len() == rec.vals.len()`
could be broken during parsing. This can cause runtime errors as in
#10693. Other commands, like `select` were also affected.
The inconsistencies are somewhat hard to see, as most nushell code
assumes an equal number of columns and values.
# Before
### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But only one value
> $record | values | to nuon
[1]
# And printing the record doesn't show the second column!
> $record | to nuon
{one: 1}
```
### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But three values
> $record | values | to nuon
[1, 2, 3]
# And printing the record doesn't show the third value!
> $record | to nuon
{one: 1, two: 2}
```
# After
### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, null]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: null}
```
### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, 2]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: 2}
```
# User-Facing Changes
Using the `--flexible` flag with `from csv` and `from tsv` will not
result in corrupted record state.

(squashed version of #10557, clean commit history and review thread)
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.
```

> 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
```
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/abd to /home/bobhy/src/rust/work/r4/dest/abd
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 pr fix clippy warnings in latest clippy version(1.72.0):
Unfortunally it's not easy to handle for [try
fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold)
warning in `start command`
Refer to known issue:
> This lint doesn’t take into account whether a function does something
on the failure case, i.e., whether short-circuiting will affect
behavior. Refactoring to try_fold is not desirable in those cases.
That's the case for our code, which does something on the failure case.
So this pr is making a little refactor on `try_commands`.
# Description
Closes#10537. Basically error message was unhelpful, and this temporary
measure adds back the nice previous nushell error message. Ideally, we
would like to add a more permanent solution mentioned in the issue
[comments](https://github.com/nushell/nushell/issues/10537#issuecomment-1743686122),
but since we want to have `ucp` as `cp` on new release, this is hackier
but way simpler so this fix should do it.
Only downside is that now behavior differs from `uutils` in the sense
that:
```
uutils:
> cp a foo/ bar
ls bar
# foo/a
nushell:
>ucp a foo/ bar
# directory error (not copied) ....
```
So, since its non fatal error, uutils copies a, but nushell errors out
with nothing copied. If we go to option 3 mentioned above, then we can
decide what we want to do, and perhaps continue on a non fatal error.

# Description
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.
update: here's an example of the error you'll see:

> [!NOTE]
> This PR description originally used examples where the `generator`
closure returned a list. It has since been updated to use records
instead.
The `unfold` command allows users to dynamically generate streams of
data. The stream is generated by repeatedly invoking a `generator`
closure. The `generator` closure accepts a single argument and returns a
record containing two optional keys: 'out' and 'next'. Each invocation,
the 'out' value, if present, is added to the stream. If a 'next' key is
present, it is used as the next argument to the closure, otherwise
generation stops.
The name "unfold" is borrowed from other functional-programming
languages. Whereas `fold` (or `reduce`) takes a stream of values and
outputs a single value, `unfold` takes a single value and outputs a
stream of values.
### Examples
A common example of using `unfold` is to generate a fibbonacci sequence.
See
[here](6ffdac103c/src/sources.rs (L65))
for an example of this in rust's `itertools`.
```nushell
> unfold [0, 1] {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} } | first 10
───┬────
0 │ 0
1 │ 1
2 │ 1
3 │ 2
4 │ 3
5 │ 5
6 │ 8
7 │ 13
8 │ 21
9 │ 34
───┴────
```
This command is particularly useful when consuming paginated APIs, like
Github's. Previously, nushell users might use a loop and buffer
responses into a list, before returning all responses at once. However,
this behavior is not desirable if the result result is very large. Using
`unfold` avoids buffering and allows subsequent pipeline stages to use
the data concurrently, as it's being fetched.

be good to document the semantics of `unfold` and provide some in-depth
examples showcasing what it can accomplish.

After this change, we need to use `-c` flag like this:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham }
```
But we can rename many columns easily, here is another example:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham, b: ham2 }
```
# Description
Closes#10441
Uses `String::to_lowercase()` when the file's extension `ext` is parsed
to allow `from_decl(format!("from {ext}"))` to return the desired output
regardless of extension case.
It doesn't work with sqlite files since those are handled earlier in the
parsing but I think is good- since there's no standard file extension
used by sqlite so a user will likely want case sensitivity in that case.
This also has the (possibly undesired) effect of making `open`
completely case insensitive, e.g. `open foo.JSON` will work on a file
named `foo.json` and vice versa. This is good on Windows as it treats
`foo.json` and `foo.JSON` as the same file, but may not be the desired
behaviour on Unix.
If this behaviour is undesired I assume it would be fixed with a
`#[cfg(not(unix))]` attribute on the `to_lowercase()` operation but that
produces slightly "uglier" code that I didn't wish to submit unless
necessary.
old behaviour:

# Description
`glob` code was using pattern as provided by user. If that had leading
`..\`, `wax::Glob` is documented to treat them as literal chars to be

Fix is to use `wax::Glob.partition()` to split such invariant prefixes
off the pattern and tack them onto the working directory computed

thanks to @jntrnr and their super useful tips on this PR, i learned
about the parser + evaluation, so 🙏
# Description
because we already have `null` as the value of the type `nothing` and as
a followup to the two other attempts of mine, i propose to remove the
redundant `$nothing` built-in variable 😋
this PR is the first step, deprecating `$nothing`.
a followup PR will remove it altogether and wait for 0.87 👍⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added,
parsing `$nothing` will create it, finally a `Value::Nothing` will be
produced and a warning will be reported.
this PR already fixes the `toolkit.nu` module so that it does not throw
a bunch of warnings each time 👌
# User-Facing Changes
`$nothing` is now deprecated and will be removed in 0.87

Closes#5436
When I opened this issue more than a year ago, I mainly wanted the
following capacity: easily access the full env and have the hability to
update it when a new version of `nushell` comes out.
With this PR I can now do the following:
```nu
source-env ~/.config/nushell/defaults/env.nu
source ~/.config/nushell/defaults/config.nu
# Update nushell default config & env file (run this after a version update)
def update-defaults [] {
config env --default | save -f ~/.config/nushell/defaults/env.nu
config nu --default | save -f ~/.config/nushell/defaults/config.nu
}
```
Which is more than enough for me. Along with `nushell` respecting the
XDG spec on macOS (`dirs-next` should be banned for CLI tools on macOS),
this should be one of the last hurdle before fully switching for me!

Are the docs for commands generated automatically or do I need to make a
PR there too ? It's no problem if so, just point me at instructions if
there are any :)
# Description
Fixes: #10450
This pr differentiating between `--x: bool` and `--x`
Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x # not allowed, you need to parse a value to the flag.
a # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```
For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo # output false
foo --option # not allowed, you need to parse a value to the flag.
foo --option true # output true
```
# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```
Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.
## Update: one more breaking change to help on #7260
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

# Description
Fixes: #10410
So the following script is possible:
```nushell
def a [b: any = null] { let b = ($b | default "default_b"); }
a "given_b"
```
## About the change
When parsing signature, and nushell meets something like `a: any`, it
force the parser to treat `a` as `any` type. This is what
`arg_explicit_type` means, it's only set when we goes into
`ParseMode::TypeMode`, and it will be reset to `false` if the token goes
to next argument.
so, when we have something like this: `def a [b: any = null] { $b }`,
the type of `$b` won't be overwritten.
But if we have something like this: `def a [b = null] { $b }`, the type
of `$b` is not annotated, so we make it to be `nothing`(which is the
type of null)

# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320
Now make the internal codebase consistent in referring to this data type
as `float`.
Work for #10332
# User-Facing Changes
`decimal` has been removed as a type name/symbol.
Instead of
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use
```nushell
def foo [bar: float] float -> float {}
```
Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`
# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`

# User-Facing Changes
Nothing too radical, just experience improvements. Users won't need to
pass the values through `unique` beforehand.
# Description
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.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)
Work for #10233
## Details
- Remove python-like string multiplication.
- Workaround for indentation
- This should probably be addressed with a purpose built command
- Remove special const-eval error test
# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)
We should bless a good alternative before landing this

# 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.
Work related to #10233
# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.
# Tests + Formatting
Remove the associated test
# Description
This changes `echo` to work more closely to what users of other shells
would expect:
* when redirected, `echo` works as before and sends values through the
pipeline
* when not redirected, `echo` will print values to the screen/terminal
# User-Facing Changes
A standalone `echo` now will print to the terminal, if not redirected.
The `echo` command is no longer const eval-able, as it will now print to
the terminal in some cases.

`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

This generally makes for nicer APIs, as you are not forced to use an
existing allocation covering the full `String`.
Some exceptions remain where the underlying type requirements favor it.

# Description
Fixes#10300 , where using variables didnt work with `ucp` as it was
only expecting a `Expr::FilePath`.
Before: (from the issue)
```
❯ ucp -r $var $folder
Error: × Missing file operand
╭─[entry #40:1:1]
1 │ ucp -r $var $folder
· ─┬─
· ╰── Missing file operand
╰────
help: Please provide source and destination paths
```
Now:
```
`ucp -r $var $folder`
# success
```
Also added the test to ensure its working:) . Oh, and I tweaked again
slightly the messages on two tests because now the whole `path` is
printed rather than `a`. Say:
```
#before
`cp a a` --> 'a' and 'a' are the same file
# now
`cp a a` --> /home/current/location/a and /home/current/location/a are the same file
```

This PR is in relation to #10215
# Description
This PR introduces `reject` to receive list of columns or rows as
argument.
This change is similar to change of `select` and the code used is
similar.
# User-Facing Changes
The user will be able to pass a list as rejection arguments.
```nushell
let arg = [ type size ]
[[name type size]; [ cargo.toml file 20mb ] [ Cargo.lock file 20mb] [src dir 100mb]] | reject $arg
```
# Description
This PR fixes `reject` failing when providing row items in ascending
order.
# User-Facing Changes
users can now `reject` multiple rows independently of each other.
```nushell
let foo = [[a b]; [ 1 2] [3 4] [ 5 6]]
# this will work independant of the order
print ($foo | reject 2 1)
print ($foo | reject 1 2)
```

# Description
Hi. Basically, this is a continuation of the work that @fdncred started.
Given some nice discussions on #9463 , and [merged uutils
PR](https://github.com/uutils/coreutils/pull/5152) from @tertsdiepraam
we have decided to give the `cp` command the `crawl` stage as it was
named.
> [!NOTE]
Given that the `uutils` crate has not made the release for the merged
PR, just make sure you checkout latest and put it in the required place
to make this PR work.
The aim of this PR is for is to see how to move forward using `uutils`
crate. In order to getting this started, I have made the current
`nushell cp tests` pass along with some extra ones I copied over from
the `uutils` repo.
With all of that being said, things that would be nice to decide, and
keep working on:
Crawl:
- Handling of certain `named` flags, with their long and short
forms(e.g. --update, --reflink, --preserve, etc), and using default
values. Maybe `-u` can already have a `default_missing_value`.
- Should we maybe just support one single option `switch` flags (see
`--backup` in code) as a contrast to the other named args.
- Complete test coverage from `uutils`. They had > 100 tests, and I
could only port like 12 as they are a bit time consuming given they
cannot be straight up copy pasted. Maybe we do not need all >100, but
maybe the more relevant to what we want.
- Refactor this code
Walk:
- Non fatal errors on `copy` from `utils`. Currently it just sends it to
stdout but errors have no span
- Better integration
An added possibility is the addition of `SyntaxShape::OneOf()` for
`Named` arguments which was briefly mentioned in the discord server, but
that is still to be decided. This could greatly improve some of the
integration. This would enable something like `cp --preserve [all
timestamp]` or `cp --preserve all` to both work.
I did not want to keep holding on this, and wait till I was happy with
the code because I think its nice if everyone can start up and suggest
refactors, but the main important part now was getting it out the door,
as if I take my sweet time this will take way longer 😛

# 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.

this is @fdncred's findings 😋

# User-Facing Changes
```nushell

Fix https://github.com/nushell/nushell/issues/10136
# Description
Current nushell only handle path containing '*' as match pattern and
treat '?' as just normal path.
This pr makes path containing '?' is also processed as pattern.
🔴 **Concerns: Need to design/comfirm a consistent rule to handle
dirs/files with '?' in their names.**
Currently:
- if no dir has exactly same name with pattern, it will print the list
of matched directories
- if pattern exactly matches an empty dir's name, it will just print the
empty dir's content ( i.e. `[]`)
- if pattern exactly matches an dir's name, it will perform pattern
match and print all the dir contains
e.g.
```bash
mkdir src
ls s?c
```

They relied on the `nu_plugin_inc` but where behind a feature flag that
isn't actually defined anywhere. These tests of `update` or `upsert`
shouldn't really depend on `inc` so I decided to remove them outright as
they haven't been used to exercise the commands under test.
As described in Issue #8670, removed `pipeline()` wherever its argument
contained no line breaks.

# Description
* added a flag to `from csv --ascii` that replaces the given `separator
with the unicode separator x1f https://www.codetable.net/hex/1f (aka
Information Separator One)
# User-Facing Changes
New flags are available for `from csv` ( `--ascii` or short `-a`)
# Tests + Formatting
There are no tests at the moment. Code has been formatted.

machine)
# 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
As described in https://github.com/nushell/nushell/issues/9912, the
`http` command could display the request headers with the `--full` flag,
which could help in debugging the requests. This PR adds such
functionality.
# User-Facing Changes
If `http get` or other `http` command which supports the `--full` flag
is invoked with the flag, it used to display the `headers` key which
contained an table of response headers. Now this key contains two nested
keys: `response` and `request`, each of them being a table of the
response and request headers accordingly.

Currently `parse` acts like a `.filter` over an iterator, except that it
emits `None` for elements that can't be parsed. This causes consumers of
the adapted iterator to stop iterating too early. The correct behaviour
is to keep pulling the inner iterator until either the end of it is
reached or an element can be parsed.

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.
cc: @fdncred
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.

# Description
Closes: #9891
I also think it's good to keep command name consistency.
And moving `date format` to deprecated.
# User-Facing Changes
Running `date format` will lead to deprecate message:
```nushell

# Description
See also: #9743
Before:
`http <subcommand> -H` took a list in the form:
```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```
Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
Cookie: "acc=barfoo",
User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```
is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```
# User-Facing Changes
No breaking changes, but Records can now also be passed to `http
<subcommand> -H`.

# After Submitting
# Description
This command also flat-maps and doesn't create a table like `split
column`
We should probably reconsider the flatmap behavior like in #9739
but for the #9812 hotfix this is an unwelcome breaking change.
# User-Facing Changes
None
# Tests + Formatting
- Fix signature of `split row`
- Add test for output signature
# Description
This PR fixes this not working `ansi --list | columns`. I originally
thought that this was a problem with `columns` but it turned out to be a
problem with the input output type of `ansi`. Since `ansi` was only
allowed to return strings, `columns` thought it was getting a string,
but it was a table.

## About the change
Before the pr, nushell only parse redirection target as a string(through
`parse_string` call).
In the pr, I'm trying to make the value more generic(using `parse_value`
with `SyntaxShape::Any`)
And during eval stage, we guard it to only eval `String`,
`StringInterpolation`, `FullCellPath`, `FilePath`, so other type of
redirection target like `1ms` won't be permitted.
# User-Facing Changes
After the pr: redirection support something like the following:
1. `let a = "x"; cat toolkit.nu o> $a`
2. `let a = "x"; cat toolkit.nu o> $"($a).txt"`
3. `cat toolkit.nu out> ("~/a.txt" | path expand)`

# 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.
# Tests + Formatting
# After Submitting
# 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 adds input/output types to custom commands. These are input/output
pairs that related an input type to an output type.
For example (a single int-to-int input/output pair):
```
def foo []: int -> int { ... }
```
You can also have multiple input/output pairs:
```
def bar []: [int -> string, string -> list<string>] { ... }
```
These types are checked during definition time in the parser. If the
block does not match the type, the user will get a parser error.
This `:` to begin the input/output signatures should immediately follow
the argument signature as shown above.
The PR also improves type parsing by re-using the shape parser. The
shape parser is now the canonical way to parse types/shapes in user
code.
This PR also splits `extern` into `extern`/`extern-wrapped` because of
the parser limitation that a multi-span argument (which Signature now
is) can't precede an optional argument. `extern-wrapped` now takes the
required block that was previously optional.
# User-Facing Changes
The change to `extern` to split into `extern` and `extern-wrapped` is a
breaking change.

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

be exactly equal to the first row even if it had less columns than the

cause panics in other commands if rows ended up having more columns than
values.

# Description
in most of the tests for `last` and `first`, we do not need to
- give `cwd` to `nu!`
- use pipeline as the tests are all short pipes
- use `r#" ... "#` as the pipes never contain quotes
this PR removes all these points from the tests for the `last` and
`first` commands.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

- Previously, `last` on binary data returned an integer. Now it returns
a binary
- Now, `[] | last` and `[] | first` are both errors.
- Now, `ls | table | first` and `ls | table | last` are both errors.
# Description
This changes the default behaviour of `let` to be able to take a
pipeline as its initial value.
For example:
```
> let x = "hello world" | str length
```
This is a change from the existing behaviour, where the right hand side
is assumed to be an expression. Pipelines are more general, and can be
more powerful.
My google foo is failing me, but this also fixes this issue:
```
let x = foo
```
Currently, this reads `foo` as a bareword that gets converted to a
string rather than running the `foo` command. In practice, this is
really annoying and is a really hard to spot bug in a script.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
`let` gains the power to be assigned via a pipeline. However, this
changes the behaviour of `let x = foo` from assigning the string "foo"
to `$x` to being "run the command `foo` and give the result to `$x`"

# 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 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
![grafik](https://github.com/nushell/nushell/assets/15833959/c377bf1d-d47c-4c25-a342-9a348539f242)
## 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`

# 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.

# Description
Make sure that our different crates that contain commands can be
compiled in parallel.
This can under certain circumstances accelerate the compilation with
sufficient multithreading available.
## Details
- Move `help` commands from `nu-cmd-lang` back to `nu-command`
- This also makes sense as the commands are implemented in an
ANSI-terminal specific way
- Make `nu-cmd-lang` only a dev dependency for `nu-command`
- Change context creation helpers for `nu-cmd-extra` and
`nu-cmd-dataframe` to have a consistent api used in
`src/main.rs`:`get_engine_state()`
- `nu-command` now indepedent from `nu-cmd-extra` and `nu-cmd-dataframe`
that are now dependencies of `nu` directly. (change to internal
features)
- Fix tests that previously used `nu-command::create_default_context()`
with replacement functions
## From scratch compilation times:
just debug (dev) build and default features
```
cargo clean --profile dev && cargo build --timings
```

Trying to fix#9394.
The problem with PR #9159 seems to be when searching for multiple terms,
each term is checked against the original values. It outputs a new value
for each such check, thus introducing replication for each search term.
As a result, it works fine with num of search term = 1.
# Description
It's not a good idea to save `stdout` and `stderr` to the same file from
`save` command directly.
Because it saves `stdout` and `stderr` in different thread, which leads
to in-consistent output. As replace, we can use `o+e` redirection to fix
the issue

This change introduces new `search_result` style supported in the color
config. The change also removes obsolete check for `config.ls_colors`
for computing the style. `config.ls_colors` has been removed last year,
so this removes the reference to the obsolete flag, along with a cleanup
that removes all the code that used to rely on ls_colors for
highlighting search results.

Closes#9003.
This PR changes `group-by` so that its optional argument is interpreted
as a cell path. In turn, this lets users use `?` to ignore rows that are
missing the column they wish to group on. For example:
```
> [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo
Error: nu:🐚:column_not_found
× Cannot find column
╭─[entry #3:1:1]
1 │ [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo
· ─────┬──── ─┬─
· │ ╰── cannot find column 'foo'
· ╰── value originates here
╰────
> [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo?
╭─────┬───────────────╮
│ 123 │ [table 1 row] │
│ 234 │ [table 1 row] │
╰─────┴───────────────╯
```
~~This removes the ability to pass `group-by` a closure or block (I
wasn't able to figure out how to make the 2 features coexist), and so it
is a breaking change. I think this is OK; I didn't even know `group-by`
could accept a closure or block because there was no example for that
functionality.~~
# 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}

Related to #8368.
# Description
as planned in #8311, the `enter`, `shells`, `g`, `n` and `p` commands
have been re-implemented in pure-`nushell` in the standard library.
this PR removes the `rust` implementations of these commands.
- all the "shells" tests have been removed from
`crates/nu-commnand/tests/commands/` in
2cc6a82da6, except for the `exit` command
- `cd` does not use the `shells` feature in its source code anymore =>
that does not change its single-shell behaviour
- all the command implementations have been removed from
`crates/nu-command/src/shells/`, except for `exit.rs` => `mod.rs` has
been modified accordingly
- the `exit` command now does not compute any "shell" related things
- the `--now` option has been removed from `exit`, as it does not serve
any purpose without sub-shells
# User-Facing Changes
users may now not use `enter`, `shells`, `g`, `n` and `p`
now they would have to use the standard library to have access to
equivalent features, thanks to the `dirs.nu` module introduced by @bobhy
in #8368

- 🟢 `toolkit clippy`

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

〉help dflts
sample function to show defaults in help
Usage:
> dflts {flags} <arg1> (arg2)
Flags:
--switch - switch -- no default here
--named <Int> - named flag, typed, but no default
--other <String> - flag with default (default: 'def')
--hard <Record([("foo", Int), ("bar", String), ("bas", Boolean)])> - default can be compound type (default: {foo: 22, bar: 'other worlds', bas: false})
-h, --help - Display the help message for this command
Parameters:
arg1 <string>: mandatory positional
arg2 <string>: optional positional (optional, default: 'abc')
```
Compared to (relevant bits of) help output previously:
```
Flags:
-h, --help - Display the help message for this command
-, --switch - no default here
-, --named <int> - named flag, no default
-, --other <string> - flag
-, --hard <record<foo: int, bar: string, bas: bool>> - default can be compound type
Signatures:
<any> | dflts <string> <string> -> <any>
Parameters:

# Description
This PR fixes issue #9043 where find -v was returning empty tables
and/or wrong output.
It also refactors some big code chunks with repetitions into it's own
functions.
# User-Facing Changes
# Tests + Formatting
Unit tests added for asserting changes.
# After Submitting
# Description
Before this PR, `math round` ignores the input if it's an `int`. This
results in the following behaviour:
```
> 123 | math round --precision -1
123
```
When the correct result is 120.
Now `int values` are converted to `float values` before actually
rounding up the number in order to take advantage of the float
implementation.
Fixes#9049.
# Description
Add option that combines both output streams to the `run-external`
command.
This allows you to do something like this:
```nushell
let res = do -i { run-external --redirect-combine <command that prints to stdout and stderr> } | complete
if $res.exit_code != 0 {
# Only print output when command has failed.
print "The command has failed, these are the logs:"
print $res.stdout
}
```
# User-Facing Changes
No breaking changes, just an extra option.

Added a test that checks the new option

This PR just tidies up some tests by removing unused code:
1. If the filesystem is not touched, don't use the filesystem
playground/sandbox
2. If the filesystem is not touched, don't specify the `cwd`
3. If the command is short, don't bother wrapping it in `pipeline()`
4. If the command doesn't have quotes, don't bother with a `r#"..."#`
raw string
Part of #8670.
# Description
Extends the `extern` syntax to allow commands that accept raw arguments.
This is mainly added to allow wrapper type scripts for external
commands.
This is an example on how this can be used:
```nushell
extern foo [...rest] {
print ($rest | str join ',' )
}
foo --bar baz -- -q -u -x
# => --bar,baz,--,-q,-u,-x
```
(It's only possible to accept a single ...varargs argument in the
signature)
# User-Facing Changes
No breaking changes, just extra possibilities.
# Tests + Formatting
Added a test for this new behaviour and ran the toolkit pr checker
# After Submitting
This is advanced functionality but it should be documented, I will open
a new PR on the book for that

# Description
Previously, `par-each` acted like a `flatmap`: first mapping the data,
then applying a `flatten`. This is unlike `each`, which just maps the
data. Now `par-each` works like `each` in this regard, leaving nested
data unflattened.
Fixes#8497
# User-Facing Changes
Previously:
`[1 2 3] | par-each {|e| [$e, $e] }` --> `[1,1,2,2,3,3]`
Now:
`[1 2 3] | par-each {|e| [$e, $e] }` --> `[[1,1],[2,2],[3,3]]`
# Tests
This adds one test that verifies the lack of flattening for `par-each`.
close? #8060
Quite a bit of refactoring took place.
I believe a few improvements to collapse/expand were made.
I've tried to track any performance regressions and seems like it is
fine.
I've noticed something different now with default configuration path or
something in this regard?
So I might missed something while testing because of this.
Requires some oversight.

# 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:

We were seeing duplicate entries for the std lib files, and this PR
addresses that. Each file should now only be added once.
Note: they are still parsed twice because it's hard to recover the
module from the output of `parse` but a bit of clever hacking in a
future PR might be able to do that.

# Description
Verified on discord with maintainer
Change adds regex separators in split rows/column/list. The primary
motivating reason was to make it easier to split on separators with
unbounded whitespace without requiring a lot of trim jiggery. But,
secondary motivation is the same as the set of all motivations for
adding split regex features to most languages.
# User-Facing Changes
Adds -r option to split rows/column/list.

# Description
Currently, all four of these commands return a (rather-confusing)
spanless error when passed an empty list:
```
> [] | sort
Error:
× no values to work with
help: no values to work with
```
This PR changes these commands to always output `[]` if the input is
`[]`.
```
> [] | sort
╭────────────╮
│ empty list │
╰────────────╯
> [] | uniq-by foo
╭────────────╮
│ empty list │
╰────────────╯
```
I'm not sure what the original logic was here, but in the case of `sort`
and `uniq`, I think the current behavior is straightforwardly wrong.
`sort-by` and `uniq-by` are a bit more complicated, since they currently
try to perform some validation that the specified column name is present
in the input (see #8667 for problems with this validation, where a
possible outcome is removing the validation entirely). When passed `[]`,
it's not possible to do any validation because there are no records.
This opens up the possibility for situations like the following:
```
> [[foo]; [5] [6]] | where foo < 3 | sort-by bar
╭────────────╮
│ empty list │
╰────────────╯
```
I think there's a strong argument that `[]` is the best output for these
commands as well, since it makes pipelines like `$table | filter
$condition | sort-by $column` more predictable. Currently, this pipeline
will throw an error if `filter` evaluates to `[]`, but work fine
otherwise. This makes it difficult to write reliable code, especially
since users are not likely to encounter the `filter -> []` case in
testing (issue #5957). The only workaround is to insert manual checks
for an empty result. IMO, this is significantly worse than the "you can
typo a column name without getting an error" problem shown above.
Other commands that take column arguments (`get`, `select`, `rename`,
etc) already have `[] -> []`, so there's existing precedent for this
behavior.
The core question here is "what columns does `[]` have"? The current
behavior of `sort-by` is "no columns", while the current behavior of
`select` is "all possible columns". Both answers lead to accepting some
likely-buggy code without throwing on error, but in order to do better
here we would need something like `Value::Table` that tracks columns on
empty tables.
If other people disagree with this logic, I'm happy to split out the
`sort-by` and `uniq-by` changes into another PR.
# User-Facing Changes
`sort`, `uniq`, `sort-by`, and `uniq-by` now return `[]` instead of
throwing an error when input is `[]`.

The existing behavior was not documented, and the new behavior is what
you would expect by default, so I don't think we need to update
documentation.

This PR fixes a bug introduced in
https://github.com/nushell/nushell/pull/8571.
We were accidentally converting a `Result<Value, ShellError>` to JSON
instead of converting a `Value`. The upshot was that we were sending
JSON like `{"Ok":{"foo":"bar"}}` instead of `{"foo":"bar"}`.
This was an easy bug to miss, because `ureq::send_json()` accepts any
`impl serde::Serialize`. I've added a test to prevent regression.
# Description
This removes all the old style of quasi-ranges before we had full range
support from `str substring`. Functionality should otherwise work, but

This PR fixes `select` when given an empty list; it used to return
`null` when given an empty list. I also cleaned up other `select` tests
while I was in the area.
### Before:
```
> [] | select a | to nuon
null
```
### After:
```
> [] | select a | to nuon
[]
```
It looks like the previous behaviour was accidentally introduced by
[this PR](https://github.com/nushell/nushell/pull/7639).
# Description
Require that any value that looks like it might be a number (starts with
a digit, or a '-' + digit, or a '+' + digits, or a special form float
like `-inf`, `inf`, or `NaN`) must now be treated as a number-like
value. Number-like syntax can only parse into number-like values.
Number-like values include: durations, ints, floats, ranges, filesizes,
binary data, etc.

# Description
This removes autoprinting the final value of a loop, much in the same
spirit as not autoprinting values at the end of statements. As we fix
these corner cases, it becomes more consistent that to print to the
screen in a script, you use the `print` command.
This gives a noticeable performance improvement as a bonus.

Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`)
would throw an error if either side was null. After this PR, these
operators return null if either side (or both) is null.
### Examples
```bash
1 < 3 # true
1 < null # null
null < 3 # null
null < null # null
```
### Motivation
JT [asked the C#
folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140)
and this is apparently the approach they would choose for comparison
operators if they could start from scratch.
This PR makes `where` more convenient to use on jagged/missing data. For
example, we can now filter on columns that may not be present in every
row:
```
> [{foo: 123} {}] | where foo? > 10
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │ 123 │
╰───┴─────╯
```
this pr refines #8270 and closes#8109
# description
examples:
the original syntax is okay
```nu

# Description
**TL;DR**: this PR adds `--indent <int>`, `--tabs <int>` and `--raw` to
control a bit more the `string` output of `to nuon`, as done in `to
json` already, the goal being to promote the `NUON` format through easy
to read and formatted output `.nuon` files 😋
### outside of `crates/nu-command/src/formats/to/nuon.rs`
as the signature of `value_to_string` has changed, the single call to it
outside of its module definition has been changed to use default values
=> `value_to_string(&value, Span::unknown(), 0, &None)` in
`crates/nu-command/src/filters/uniq.rs`
### changes to `ToNuon` in `crates/nu-command/src/formats/to/nuon.rs`
- the signature now features `--raw`, `--indent <int>` and `--tabs
<int>`
- the structure of the `run` method is inspired from the one in `to
json`
- we get the values of the arguments
- we convert the input to a usable `Value`
- depending on whether the user raised `--raw`, `--indent` or `--tabs`,
we call the conversion to `string` with different values of the
indentation, starting at depth 0
- finally, we return `Ok` or a `ShellError::CantConvert` depending on
the conversion result
- some tool functions
- `get_true_indentation` gives the full indentation => `indent` repeated
`depth` times
- `get_true_separators` gives the line and field separators => a `("\n",
"")` when using some formatting or `("", " ")` when converting as pure
string on a single line
the meat of `nuon.rs` is now the `value_to_string` recursive function:
- takes the depth and the indent string
- adds correct newlines, space separators and indentation to the output
- calls itself with the same indent string but `depth + 1` to increase
the indentation by one level
- i used the `nl`, `idt`, `idt_po` (**i**n**d**en**t** **p**lus **o**ne)
and `idt_pt` (**i**n**d**en**t** **p**lus **t**wo) to make the
`format!`s easier to read
# User-Facing Changes
users can now
- control the amount and nature of NUON string output indentation with
- `--indent <number of " " per level>`
- `--tabs <number of "\t" per level>`
- use the previous behaviour of `to nuon` with the `--raw` option
- have new examples with `help to nuon`
> **Note**
> the priority order of the options is the following
> 1. `--raw`
> 2. `--tabs`
> 3. `--indent`
>
> the default is `--indent 2`
# Tests + Formatting
### new tests
- tests involving the string output of `to nuon`, i.e. tests not of the
form `... | to nuon | from nuon ...`, now use the `to nuon --raw`
command => this is the smallest change to have the tests pass, as the
new `to nuon --raw` is equivalent to the old `to nuon`
- in `crates/nu-command/src/formats/to/nuon.rs`, the previous example
has been replaced with three examples
- `[1 2 3] | to nuon` to show the default behaviour
- `[1 2 3] | to nuon --raw` to show the not-formatted output
- a more complex example with `{date: 2000-01-01, data: [1 [2 3] 4.56]}
| to nuon`
- the result values have been defined and the `examples` tests pass
### dev
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- 🟢 `cargo test --workspace` ~~passes but without
`to_nuon_errs_on_closure`~~ fixed in

# After Submitting
the `to nuon` page would have to be regenerated at some point due to the
new tests
# Description
This adds two different features to `open`:
* The ability to pass more than one file to `open`.
* Support for using globs in the filenames
`open` will create a list stream and stream the output if there is more
than one file opened
Examples:
```
open file1.csv file2.csv file3.csv
```
```
open *.nu | where $it =~ "echo"
```
# User-Facing Changes
Multi-file and glob support in `open`. Original `open` functionality
should continue as before.

# User-Facing Changes
when define a closure without pipe, nushell will raise error for now:
```
❯ let x = {ss ss}
Error: nu::parser::closure_missing_pipe

╭─[entry #2:1:1]

· ───┬───
· ╰── Parsing as a closure, but || is missing
╰────
help: Try add || to the beginning of closure
```
`any`, `each`, `all`, `where` command accepts closure, it forces user
input closure like `{||`, or parse error will returned.
```
❯ {major:2, minor:1, patch:4} | values | each { into string }
Error: nu::parser::closure_missing_pipe

╰────
help: Try add || to the beginning of closure
```
`with-env`, `do`, `def`, `try` are special, they still remain the same,
although it says that it accepts a closure, but they don't need to be
written like `{||`, it's more likely a block but can capture variable
outside of scope:
```
❯ def test [input] { echo [0 1 2] | do { do { echo $input } } }; test aaa
aaa
```
Just realize that It's a big breaking change, we need to update config
and scripts...

# Description
Resolves issue #8370
Adds the following flags to commands `from csv` and `from tsv`:
- `--flexible`: allow the number of fields in records to be variable
- `-c --comment`: a comment character to ignore lines starting with it
- `-q --quote`: a quote character to ignore separators in strings,
defaults to '\"'
- `-e --escape`: an escape character for strings containing the quote
character
Internally, the `Value` struct has an additional helper function
`as_char` which converts it to a single `char`
# User-Facing Changes
The single quoted string `'\t'` can no longer be used as a parameter for
the flag `--separator '\t'` as it is interpreted as a two-character
string. One needs to use from now on the flag with a double quoted
string like so: `-s "\t"` which correctly interprets the string as a
single `char`.
# Description
This adds back support for parens around params, eg `def foo (x: int) {
... }`
# User-Facing Changes
returns to the original support before the recent parser refactor

https://github.com/nushell/nushell/pull/8379 removed the `-i` flag from
`get` and `select` because the new `?` functionality covers most of the
same use cases. However, https://github.com/nushell/nushell/issues/8480
made me realize that `-i` is still useful when dealing with cell paths
in variables.
This PR re-adds the `-i` flag to `get` and `select`. It works by just
marking every member in the cell path as optional, which will behave
_slightly_ differently than `-i` used to (previously it would suppress
any errors, even type errors) but IMO that's OK.
This reverts commit dec0a2517f.
It breaks programs like `fzf`

# Description
Fixes: #8402#8391
The cause of these issue if when we want to evaluate a expression with
`Value::Error`, nushell show error immediately. To fix the issue, we can
wrap the `Value::Error` into a `Value::Record`. So user can see the
message he want.
# User-Facing Changes
Before
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
Error: nu:🐚:division_by_zero
× Division by zero.
╭─[entry #2:1:1]
1 │ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
· ┬
· ╰── division by zero
╰────
```
After
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
error is {msg: Division by zero., debug: DivisionByZero { span: Span { start: 43104, end: 43105 } }, raw: DivisionByZero { sp
an: Span { start: 43104, end: 43105 } }}
```
As we can see, error becomes a record with `msg`, `debug`, `raw`
columns.
1. msg column is a user friendly message.
2. debug column is more about `Value::Error` information as a string.
3. raw column is a `Value::Error` itself, if user want to re-raise the
error, just use `$e | get raw`

Please provide feedback if you have the time!
## Summary
This PR lets you use `?` to indicate that a member in a cell path is
optional and Nushell should return `null` if that member cannot be
accessed.
Unlike the previous PR, `?` is now a _postfix_ modifier for cell path
members. A cell path of `.foo?.bar` means that `foo` is optional and
`bar` is not.
`?` does _not_ suppress all errors; it is intended to help in situations
where data has "holes", i.e. the data types are correct but something is
missing. Type mismatches (like trying to do a string path access on a
date) will still fail.
### Record Examples
```bash
{ foo: 123 }.foo # returns 123
{ foo: 123 }.bar # errors
{ foo: 123 }.bar? # returns null
{ foo: 123 } | get bar # errors
{ foo: 123 } | get bar? # returns null
{ foo: 123 }.bar.baz # errors
{ foo: 123 }.bar?.baz # errors because `baz` is not present on the result from `bar?`
{ foo: 123 }.bar.baz? # errors
{ foo: 123 }.bar?.baz? # returns null
```

# Breaking changes
1. Column names with `?` in them now need to be quoted.
2. The `-i`/`--ignore-errors` flag has been removed from `get` and
`select`
1. After this PR, most `get` error handling can be done with `?` and/or
`try`/`catch`.
4. Cell path accesses like this no longer work without a `?`:
```bash
〉[{a:1 b:2} {a:3}].b.0
2
```
We had some clever code that was able to recognize that since we only
want row `0`, it's OK if other rows are missing column `b`. I removed
that because it's tricky to maintain, and now that query needs to be
written like:
```bash
〉[{a:1 b:2} {a:3}].b?.0
2
```
I think the regression is acceptable for now. I plan to do more work in
the future to enable streaming of cell path accesses, and when that
happens I'll be able to make `.b.0` work again.

# Description
The correction made here concerns the issue #8431. Indeed, the algorithm
initially proposed to remove elements of a `vector` performed a loop
with `remove` and an incident therefore appeared when several values
were equal because the deletion was done outside the length of the
vector:
```rust
let mut found = false;
for (i, col) in cols.clone().iter().enumerate() {
if col == col_name {
cols.remove(i);
vals.remove(i);
found = true;
}
}
```
Then, `[[a, a]; [1, 2]] | reject a: ` gave `thread 'main' panicked at
'removal index (is 1) should be < len (is 1)',
crates/nu-protocol/src/value/mod.rs:1213:54`.
The proposed correction is therefore the implementation of the
`retain_mut` utility dedicated to this functionality.
```rust
let mut found = false;
let mut index = 0;
cols.retain_mut(|col| {
if col == col_name {
found = true;
vals.remove(index);
false
} else {
index += 1;
true
}
});
```
# Description
Prevents alias from aliasing itself. It allows a commonly requested
pattern similar to `alias ls = ls -l`.
One small issue is that the syntax highlighting is a bit off:
