Replace panics with errors in thread spawning (#12040)
# Description Replace panics with errors in thread spawning. Also adds `IntoSpanned` trait for easily constructing `Spanned`, and an implementation of `From<Spanned<std::io::Error>>` for `ShellError`, which is used to provide context for the error wherever there was a span conveniently available. In general this should make it more convenient to do the right thing with `std::io::Error` and always add a span to it when it's possible to do so. # User-Facing Changes Fewer panics! # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` |

Glob: don't allow implicit casting between glob and string (#11992)
# Description
As title, currently on latest main, nushell confused user if it allows
implicit casting between glob and string:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g }
glob-test $x
```
It always expand the glob although `$x` is defined as a string.
This pr implements a solution from @kubouch :
> We could make it really strict and disallow all autocasting between
globs and strings because that's what's causing the "magic" confusion.
Then, modify all builtins that accept globs to accept oneof(glob,
string) and the rules would be that globs always expand and strings
never expand
# User-Facing Changes
After this pr, user needs to use `into glob` to invoke `glob-test`, if
user pass a string variable:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g }
glob-test ($x | into glob)
```
Or else nushell will return an error.
```
3 │ glob-test $x
· ─┬
· ╰── can't convert string to glob
```
# Tests + Formatting

Rename spans in the serialized form of Value (#11972)

Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Span fields were previously renamed to `internal_span` to discourage their use in Rust code, but this change also affected the serde I/O for Value. I don't believe the Python plugin was ever updated to reflect this change. This effectively changes it back, but just for the serialized form. There are good reasons for doing this: 1. `internal_span` is a much longer name, and would be one of the most common strings found in serialized Value data, probably bulking up the plugin I/O 2. This change was never really meant to have implications for plugins, and was just meant to be a hint that `.span()` should be used instead in Rust code. When Span refactoring is complete, the serialized form of Value will probably change again in some significant way, so I think for now it's best that it's left like this. This has implications for #11911, particularly for documentation and for the Python plugin as that was already updated in that PR to reflect `internal_span`. If this is merged first, I will update that PR. This would probably be considered a breaking change as it would break plugin I/O compatibility (but not Rust code). I think it can probably go in any major release though - all things considered, it's pretty minor, and users are already expected to recompile plugins for new major versions. However, it may also be worth holding off to do it together with #11911 as that PR makes breaking changes in general a little bit friendlier. # User-Facing Changes <!-- List of all changes that impact the user experience here.

This is needed to make `tee --stderr` function in a non-surprising way. See #11928 # User-Facing Changes <!-- List of all changes that impact the user experience here.

Remove unused Index(Mut) impls on AST types (#11903)
# Description Both `Block` and `Pipeline` had `Index`/`IndexMut` implementations to access their elements, that are currently unused. Explicit helpers or iteration would generally be preferred anyways but in the current state the inner containers are `pub` and are liberally used. (Sometimes with potentially panicking indexing or also iteration) As it is potentially unclear what the meaning of the element from a block or pipeline queried by a usize is, let's remove it entirely until we come up with a better API. # User-Facing Changes None Plugin authors shouldn't dig into AST internals |

Now it will format time based on `LC_TIME`. For example, ``` // my locale `nl_NL.UTF-8` ❯ date now | format date '%x %X' 20-02-24 17:17:12 $env.LC_TIME = "en_US.UTF-8" ❯ date now | format date '%x %X' 02/20/2024 05:16:28 PM ``` Note that I also changed the `default_env.nu` as otherwise the Time will show AM/PM twice.

Add Value::coerce_str (#11885)
# Description Following #11851, this PR adds one final conversion function for `Value`. `Value::coerce_str` takes a `&Value` and converts it to a `Cow<str>`, creating an owned `String` for types that needed converting. Otherwise, it returns a borrowed `str` for `String` and `Binary` `Value`s which avoids a clone/allocation. Where possible, `coerce_str` and `coerce_into_string` should be used instead of `coerce_string`, since `coerce_string` always allocates a new `String`. |

Name the Value conversion functions more clearly (#11851)
# Description This PR renames the conversion functions on `Value` to be more consistent. It follows the Rust [API guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv) for ad-hoc conversions. The conversion functions on `Value` now come in a few forms: - `coerce_{type}` takes a `&Value` and attempts to convert the value to `type` (e.g., `i64` are converted to `f64`). This is the old behavior of some of the `as_{type}` functions -- these functions have simply been renamed to better reflect what they do. - The new `as_{type}` functions take a `&Value` and returns an `Ok` result only if the value is of `type` (no conversion is attempted). The returned value will be borrowed if `type` is non-`Copy`, otherwise an owned value is returned. - `into_{type}` exists for non-`Copy` types, but otherwise does not attempt conversion just like `as_type`. It takes an owned `Value` and always returns an owned result. - `coerce_into_{type}` has the same relationship with `coerce_{type}` as `into_{type}` does with `as_{type}`. - `to_{kind}_string`: conversion to different string formats (debug, abbreviated, etc.). Only two of the old string conversion functions were removed, the rest have been renamed only. - `to_{type}`: other conversion functions. Currently, only `to_path` exists. (And `to_string` through `Display`.) This table summaries the above: | Form | Cost | Input Ownership | Output Ownership | Converts `Value` case/`type` | | ---------------------------- | ----- | --------------- | ---------------- | -------- | | `as_{type}` | Cheap | Borrowed | Borrowed/Owned | No | | `into_{type}` | Cheap | Owned | Owned | No | | `coerce_{type}` | Cheap | Borrowed | Borrowed/Owned | Yes | | `coerce_into_{type}` | Cheap | Owned | Owned | Yes | | `to_{kind}_string` | Expensive | Borrowed | Owned | Yes | | `to_{type}` | Expensive | Borrowed | Owned | Yes | # User-Facing Changes Breaking API change for `Value` in `nu-protocol` which is exposed as part of the plugin API. |

Support redirect stderr and stdout+stderr with a pipe (#11708)
# Description Close: #9673 Close: #8277 Close: #10944 This pr introduces the following syntax: 1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu --testbin echo_env_stderr FOO e>| str length` 2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command, example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>| str length` Note: it only works for external commands. ~There is no different for internal commands, that is, the following three commands do the same things:~ Edit: it raises errors if we want to pipes for internal commands ``` ❯ ls e>| str length Error: × `e>|` only works with external streams ╭─[entry #1:1:1] 1 │ ls e>| str length · ─┬─ · ╰── `e>|` only works on external streams ╰──── ❯ ls e+o>| str length Error: × `o+e>|` only works with external streams ╭─[entry #2:1:1] 1 │ ls e+o>| str length · ──┬── · ╰── `o+e>|` only works on external streams ╰──── ``` This can help us to avoid some strange issues like the following: `$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length` Which is hard to understand and hard to explain to users. # User-Facing Changes Nan # Tests + Formatting To be done # After Submitting Maybe update documentation about these syntax. |

Enforce call stack depth limit for all calls (#11729)
# 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.

fix exit_code handling when running a scripts with ctrlc (#11466)
# 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. # User-Facing Changes ## Before ``` > nu -c "^sleep 3" # press ctrl-c > echo $env.LAST_EXIT_CODE 0 ``` ## After ``` > nu -c "^sleep 3" # press ctrl-c > echo $env.LAST_EXIT_CODE 255 ``` # Tests + Formatting None, sorry that I don't think it's easy to test the ctrlc behavior. # After Submitting None |

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: #9558 Fixes: #10211 Fixes: #9310 Fixes: #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)` # User-Facing Changes <!-- List of all changes that impact the user experience here.

It maybe a breaking change if a custom command's argument are annotated by `: glob`. |

Add into cell-path for dynamic cell-path creation (#11322)
# 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:
```
╭────────┬──────────────────────────────────────────────────────────────────╮
│ │ ╭──────────┬───────────────────────────────────────────────────╮ │
│ remote │ │ │ ╭───────┬───────────────────────────────────────╮ │ │

╰────────┴──────────────────────────────────────────────────────────────────╯
```
## 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.
╭─[entry #14:1:1]

Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> 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 ``` # Tests + Formatting <!-- Don't forget to add tests that cover your changes.

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 |

do not attempt to glob expand if the file path is wrapped in quotes (#11569)
# Description Fixes: #11455 ### For arguments which is annotated with `:path/:directory/:glob` To fix the issue, we need to have a way to know if a path is originally quoted during runtime. So the information needed to be added at several levels: * parse time (from user input to expression) We need to add quoted information into `Expr::Filepath`, `Expr::Directory`, `Expr::GlobPattern` * eval time When convert from `Expr::Filepath`, `Expr::Directory`, `Expr::GlobPattern` to `Value::String` during runtime, we won't auto expanded the path if it's quoted ### For `ls` It's really special, because it accepts a `String` as a pattern, and it generates `glob` expression inside the command itself. So the idea behind the change is introducing a special SyntaxShape to ls: `SyntaxShape::LsGlobPattern`. So we can track if the pattern is originally quoted easier, and we don't auto expand the path either. Then when constructing a glob pattern inside ls, we check if input pattern is quoted, if so: we escape the input pattern, so we can run `ls a[123]b`, because it's already escaped. Finally, to accomplish the checking process, we also need to introduce a new value type called `Value::QuotedString` to differ from `Value::String`, it's used to generate an enum called `NuPath`, which is finally used in `ls` function. `ls` learned from `NuPath` to know if user input is quoted. # User-Facing Changes Actually it contains several changes ### For arguments which is annotated with `:path/:directory/:glob` #### Before ```nushell > def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a > def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a > def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a') /home/windsoilder/a /home/windsoilder/a ``` #### After ```nushell > def foo [p: path] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a > def foo [p: directory] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a > def foo [p: glob] { echo $p }; print (foo "~/a"); print (foo '~/a') ~/a ~/a ``` ### For ls command `touch '[uwu]'` #### Before ``` ❯ ls -D "[uwu]" Error: × No matches found for [uwu] ╭─[entry #6:1:1] 1 │ ls -D "[uwu]" · ───┬─── · ╰── Pattern, file or folder not found ╰──── help: no matches found ``` #### After ``` ❯ ls -D "[uwu]" ╭───┬───────┬──────┬──────┬──────────╮ │ # │ name │ type │ size │ modified │ ├───┼───────┼──────┼──────┼──────────┤ │ 0 │ [uwu] │ file │ 0 B │ now │ ╰───┴───────┴──────┴──────┴──────────╯ ``` # Tests + Formatting Done # After Submitting NaN |

Allow plugins to receive configuration from the nushell configuration (#10955)
# 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

adjust some commansd input_output type (#11436)
# Description 1. Make table to be a subtype of `list<any>`, so some input_output_types of filter commands are unnecessary 2. Change some commands which accept an input type, but generates different output types.

add type check during eval time (#11475)
# 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 cc @kubouch # User-Facing Changes After this pr the following call will failed: ```nushell > outer Error: nu:🐚:cant_convert × Can't convert to string. ╭─[entry #27:1:1] 1 │ def outer [--foo: any] { 2 │ spam $foo · ──┬─ · ╰── can't convert nothing to string 3 │ } ╰──── ``` # Tests + Formatting Done # After Submitting NaN |

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"] │ ╰──────────────┴───────────────────────────────────────────────────────────────────╯ ``` |
