# Description & User-Facing Changes
This PR allows enables the following uses, which are all no-op.
```nushell
source null
source-env null
use null
overlay use null
```
The motivation for this change is conditional sourcing of files. For
example, with this change `login.nu` may be deprecated and replaced with
the following code in `config.nu`
```nushell
const login_module = if $nu.is-login { "login.nu" } else { null }
source $login_module
```
# Tests + Formatting
I'm hoping for CI to pass 😄
# After Submitting
Add a part about the conditional sourcing pattern to the website.

This PR adds type checking of all command input types at run-time.
Generally, these errors should be caught by the parser, but sometimes we
can't know the type of a value at parse-time. The simplest example is
using the `echo` command, which has an output type of `any`, so
prefixing a literal with `echo` will bypass parse-time type checking.
Before this PR, each command has to individually check its input types.
This can result in scenarios where the input/output types don't match
the actual command behavior. This can cause valid usage with an
non-`any` type to become a parse-time error if a command is missing that
type in its pipeline input/output (`drop nth` and `history import` do
this before this PR). Alternatively, a command may not list a type in
its input/output types, but doesn't actually reject that type in its
code, which can have unintended side effects (`get` does this on an
empty pipeline input, and `sort` used to before #13154).
After this PR, the type of the pipeline input is checked to ensure it
matches one of the input types listed in the proceeding command's
input/output types. While each of the issues in the "before this PR"
section could be addressed with each command individually, this PR
solves this issue for _all_ commands.
**This will likely cause some breakage**, as some commands have
incorrect input/output types, and should be adjusted. Also, some scripts
may have erroneous usage of commands. In writing this PR, I discovered
that `toolkit.nu` was passing `null` values to `str join`, which doesn't
accept nothing types (if folks think it should, we can adjust it in this
PR or in a different PR). I found some issues in the standard library
and its tests. I also found that carapace's vendor script had an
incorrect chaining of `get -i`:
```nushell
let expanded_alias = (scope aliases | where name == $spans.0 | get -i 0 | get -i expansion)
```
Before this PR, if the `get -i 0` ever actually did evaluate to `null`,
the second `get` invocation would error since `get` doesn't operate on
`null` values. After this PR, this is immediately a run-time error,
alerting the user to the problematic code. As a side note, we'll need to
PR this fix (`get -i 0 | get -i expansion` -> `get -i 0.expansion`) to
carapace.
A notable exception to the type checking is commands with input type of
`nothing -> <type>`. In this case, any input type is allowed. This
allows piping values into the command without an error being thrown. For
example, `123 | echo $in` would be an error without this exception.
Additionally, custom types bypass type checking (I believe this also
happens during parsing, but not certain)
I added a `is_subtype` method to `Value` and `PipelineData`. It
functions slightly differently than `get_type().is_subtype()`, as noted
in the doccomments. Notably, it respects structural typing of lists and
tables. For example, the type of a value `[{a: 123} {a: 456, b: 789}]`
is a subtype of `table<a: int>`, whereas the type returned by
`Value::get_type` is a `list<any>`. Similarly, `PipelineData` has some
special handling for `ListStream`s and `ByteStream`s. The latter was
needed for this PR to work properly with external commands.
Here's some examples.
Before:
```nu
1..2 | drop nth 1
Error: nu::parser::input_type_mismatch
× Command does not support range input.
╭─[entry #9:1:8]
1 │ 1..2 | drop nth 1
· ────┬───
· ╰── command doesn't support range input
╰────
echo 1..2 | drop nth 1
# => ╭───┬───╮
# => │ 0 │ 1 │
# => ╰───┴───╯
```
After this PR, I've adjusted `drop nth`'s input/output types to accept
range input.
Before this PR, zip accepted any value despite not being listed in its
input/output types. This caused different behavior depending on if you
triggered a parse error or not:
```nushell
1 | zip [2]
# => Error: nu::parser::input_type_mismatch
# =>
# => × Command does not support int input.
# => ╭─[entry #3:1:5]
# => 1 │ 1 | zip [2]
# => · ─┬─
# => · ╰── command doesn't support int input
# => ╰────
echo 1 | zip [2]
# => ╭───┬───────────╮
# => │ 0 │ ╭───┬───╮ │
# => │ │ │ 0 │ 1 │ │
# => │ │ │ 1 │ 2 │ │
# => │ │ ╰───┴───╯ │
# => ╰───┴───────────╯
```
After this PR, it works the same in both cases. For cases like this, if
we do decide we want `zip` or other commands to accept any input value,
then we should explicitly add that to the input types.
```nushell
1 | zip [2]
# => Error: nu::parser::input_type_mismatch
# =>
# => × Command does not support int input.
# => ╭─[entry #3:1:5]
# => 1 │ 1 | zip [2]
# => · ─┬─
# => · ╰── command doesn't support int input
# => ╰────
echo 1 | zip [2]
# => Error: nu:🐚:only_supports_this_input_type
# =>
# => × Input type not supported.
# => ╭─[entry #14:2:6]
# => 2 │ echo 1 | zip [2]
# => · ┬ ─┬─
# => · │ ╰── only list<any> and range input data is supported
# => · ╰── input type: int
# => ╰────
```
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
**Breaking change**: The type of a command's input is now checked
against the input/output types of that command at run-time. While these
errors should mostly be caught at parse-time, in cases where they can't
be detected at parse-time they will be caught at run-time instead. This
applies to both internal commands and custom commands.
Example function and corresponding parse-time error (same before and
after PR):
```nushell
def foo []: int -> nothing {
print $"my cool int is ($in)"
}
1 | foo
# => my cool int is 1
"evil string" | foo
# => Error: nu::parser::input_type_mismatch
# =>
# => × Command does not support string input.
# => ╭─[entry #16:1:17]
# => 1 │ "evil string" | foo
# => · ─┬─
# => · ╰── command doesn't support string input
# => ╰────
# =>
```
Before:
```nu
echo "evil string" | foo
# => my cool int is evil string
```
After:
```nu
echo "evil string" | foo
# => Error: nu:🐚:only_supports_this_input_type
# =>
# => × Input type not supported.
# => ╭─[entry #17:1:6]
# => 1 │ echo "evil string" | foo
# => · ──────┬────── ─┬─
# => · │ ╰── only int input data is supported
# => · ╰── input type: string
# => ╰────
```
Known affected internal commands which erroneously accepted any type:
* `str join`
* `zip`
* `reduce`

The [nushell/demo](https://github.com/nushell/demo) project successfully
demonstrated running Nushell in the browser using WASM. However, the
current version of Nushell cannot be easily built for the
`wasm32-unknown-unknown` target, the default for `wasm-bindgen`.
This PR introduces initial support for the `wasm32-unknown-unknown`
target by disabling OS-dependent features such as filesystem access, IO,
and platform/system-specific functionality. This separation is achieved
using a new `os` feature in the following crates:
- `nu-cmd-lang`
- `nu-command`
- `nu-engine`
- `nu-protocol`
The `os` feature includes all functionality that interacts with an
operating system. It is enabled by default, but can be disabled using
`--no-default-features`. All crates that depend on these core crates now
use `--no-default-features` to allow compilation for WASM.
To demonstrate compatibility, the following script builds all crates
expected to work with WASM. Direct user interaction, running external
commands, working with plugins, and features requiring `openssl` are out
of scope for now due to their complexity or reliance on C libraries,
which are difficult to compile and link in a WASM environment.
```nushell
[ # compatible crates
"nu-cmd-base",
"nu-cmd-extra",
"nu-cmd-lang",
"nu-color-config",
"nu-command",
"nu-derive-value",
"nu-engine",
"nu-glob",
"nu-json",
"nu-parser",
"nu-path",
"nu-pretty-hex",
"nu-protocol",
"nu-std",
"nu-system",
"nu-table",
"nu-term-grid",
"nu-utils",
"nuon"
] | each {cargo build -p $in --target wasm32-unknown-unknown --no-default-features}
```
## Caveats
This PR has a few caveats:
1. **`miette` and `terminal-size` Dependency Issue**
`miette` depends on `terminal-size`, which uses `rustix` when the target
is not Windows. However, `rustix` requires `std::os::unix`, which is
unavailable in WASM. To address this, I opened a
[PR](https://github.com/eminence/terminal-size/pull/68) for
`terminal-size` to conditionally compile `rustix` only when the target
is Unix. For now, the `Cargo.toml` includes patches to:
- Use my forked version of `terminal-size`.
- ~~Use an unreleased version of `miette` that depends on
`terminal-size@0.4`.~~
These patches are temporary and can be removed once the upstream changes
are merged and released.
2. **Test Output Adjustments**
Due to the slight bump in the `miette` version, one test required
adjustments to accommodate minor formatting changes in the error output,
such as shifted newlines.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

This shouldn't break anything but allows using some crates for targeting
`wasm32-unknown-unknown` to revive the demo page eventually.

~~Breaking the wasm support can be easily done by adding some `use`s or
by adding a new dependency, we should definitely add some CI that also
at least builds against wasm to make sure that building for it keep
working.~~

Before this PR, you can access rendered error values that are raised in
a `try/catch` block by accessing the `rendered` element of the catch
error value:
```
$ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
my cool error:
nu:🐚:directory_not_found
× Directory not found
help: /home/rose/nonexist.txt does not exist
```
However, the rendered errors don't include the labels present in the
real rendered error, which would look like this:
```
$ ls nonexist.txt
Error: nu:🐚:directory_not_found
× Directory not found
╭─[entry #46:1:4]
1 │ ls nonexist.txt
· ──────┬─────
· ╰── directory not found
╰────
help: /home/rose/nonexist.txt does not exist
```
After this PR, the rendered error includes the labels:
```
$ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
my cool error:
Error: nu:🐚:directory_not_found
× Directory not found
╭─[entry #4:1:10]
1 │ try { ls nonexist.txt } catch {|e| print "my cool error:" $e.rendered }
· ──────┬─────
· ╰── directory not found
╰────
help: /home/rose/nonexist.txt does not exist
```
This change is accomplished by using the standard error formatting code
to render an error. This respects the error theme as before without any
extra scaffolding, but it means that e.g., the terminal size is also
respected. I think this is fine because the way the error is rendered
already changed based on config, and I think that a "rendered" error
should give back _exactly_ what would be shown to the user anyway.
@fdncred, let me know if you have any concerns with the way this is
handled since you were the one who implemented this feature in the first
place.

As title, this pr is going to deprecate `--ignore-shell-errors` and

# Description
Removes the `NU_DISABLE_IR` option and some code related to evaluating
blocks with the AST
evaluator.
Does not entirely remove the AST evaluator yet. We still have some
dependencies on expression
evaluation in a few minor places which will take a little bit of effort
to fix.
Also changes `debug profile` to always include instructions, because the
output is a little
confusing otherwise, and removes the different options for
instructions/exprs.
# User-Facing Changes
- `NU_DISABLE_IR` no longer has any effect, and is removed. There is no
way to use the AST
evaluator.
- `debug profile` no longer has `--exprs`, `--instructions` options.
- `debug profile` lists `pc` and `instruction` columns by default now.
# Tests + Formatting
Eval tests fixed to only use IR.
# After Submitting
- [ ] release notes
- [ ] finish removing AST evaluator, come up with solutions for the
expression evaluation.

Bump version to `0.100.0`
# User-Facing Changes
The new release `v0.100.0` is coming...
# Description
Fixes: https://github.com/nushell/nushell/issues/13425
It's just a follow up to #13958.
User input can be a directory, in this case, we need to use the return
value of `find_in_dirs_env` carefully, so in case, I renamed
maybe_file_path to maybe_file_path_or_dir to emphasize it.
# User-Facing Changes
`$env.FILE_PWD` and `$env.CURRENT_FILE` will be more reliable to use.
# Tests + Formatting
Added 2 tests
# Description
This PR adds a couple more options for dealing with try/catch errors. It
adds a `json` version of the error and a `rendered` version of the
error. It also respects the error_style configuration point.

# Description
Fixes#13991. This was done by more clearly separating the case when a
pipeline is drained vs when it is being written (to a file).
I also added an `OutDest::Print` case which might not be strictly
necessary, but is a helpful addition.
# User-Facing Changes
Bug fix.
# Tests + Formatting
Added a test.
# After Submitting
There are still a few redirection bugs that I found, but they require
larger code changes, so I'll leave them until after the release.
# Description
Fixes: #13425
Similar to `source-env`, `use` command should also remove `FILE_PWD` and
`CURRENT_FILE` after evaluating code block in the module file.
And user input can be a directory, in this case, we need to use the
return value of `find_in_dirs_env` carefully, so in case, I renamed
`maybe_file_path` to `maybe_file_path_or_dir` to emphasize it.
# User-Facing Changes
`$env.FILE_PWD` and `$env.CURRENT_FILE` will be more reliable to use.
# Tests + Formatting
Added 2 test cases.

# Description
In this PR I replaced most of the raw usize IDs with
[newtypes](https://doc.rust-lang.org/rust-by-example/generics/new_types.html).
Some other IDs already started using new types and in this PR I did not
want to touch them. To make the implementation less repetitive, I made
use of a generic `Id<T>` with marker structs. If this lands I would try
to move make other IDs also in this pattern.
Also at some places I needed to use `cast`, I'm not sure if the type was
incorrect and therefore casting not needed or if actually different ID
types intermingle sometimes.
# User-Facing Changes
Probably few, if you got a `DeclId` via a function and placed it later
again it will still work.
This PR sets the current working directory to the location of the
Nushell executable at startup, using `std::env::set_current_dir()`. This
is desirable because after PR
https://github.com/nushell/nushell/pull/12922, we no longer change our
current working directory even after `cd` is executed, and some OS might
lock the directory where Nushell started.
The location of the Nushell executable is chosen because it cannot be
removed while Nushell is running anyways, so we don't have to worry
about OS locking it.
This PR has the side effect that it breaks buggy command even harder.
I'll keep this PR as a draft until these commands are fixed, but it
might be helpful to pull this PR if you're working on fixing one of
those bugs.

# Description
Partialy addresses #13868. `try` does not catch non-zero exit code
errors from the last command in a pipeline if the result is assigned to
a variable using `let` (or `mut`).
This was fixed by adding a new `OutDest::Value` case. This is used when
the pipeline is in a "value" position. I.e., it will be collected into a
value. This ended up replacing most of the usages of `OutDest::Capture`.
So, this PR also renames `OutDest::Capture` to `OutDest::PipeSeparate`
to better fit the few remaining use cases for it.
# User-Facing Changes
Bug fix.
# Tests + Formatting
Added two tests.
# Description
Similar to #13870 (thanks @WindSoilder), this PR adds a boolean which
determines whether to ignore any errors from an external command. This
is in order to fix#13876. I.e., `do -p` does not wait for externals to
complete before continuing.
# User-Facing Changes
Bug fix.
# Tests + Formatting
Added a test.

# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```
Before this would give:
```
╭───┬──╮
│ 0 │ │
│ 1 │ │
╰───┴──╯
```
Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input
× Eval block failed with pipeline input
╭─[entry #1:1:2]
1 │ [1 2] | each { ^false }
· ┬
· ╰── source value
╰────
Error: nu:🐚:non_zero_exit_code
× External command had a non-zero exit code
╭─[entry #1:1:17]
1 │ [1 2] | each { ^false }
· ──┬──
· ╰── exited with code 1
╰────
```
This PR fixes#12874, fixes#5960, fixes#10856, and fixes#5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes#8569).
# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).
# Tests
Added a few tests.
# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).
# Description
`cargo` somewhat recently gained the capability to store `lints`
settings for the crate and workspace, that can override the defaults
from `rustc` and `clippy` lints. This means we can enforce some lints
without having to actively pass them to clippy via `cargo clippy -- -W
...`. So users just forking the repo have an easier time to follow
similar requirements like our CI.
## Limitation
An exception that remains is that those lints apply to both the primary
code base and the tests. Thus we can't include e.g. `unwrap_used`
without generating noise in the tests. Here the setup in the CI remains
the most helpful.
## Included lints
- Add `clippy::unchecked_duration_subtraction` (added by #12549)
# User-Facing Changes
Running `cargo clippy --workspace` should be closer to the CI. This has
benefits for editor configured runs of clippy and saves you from having
to use `toolkit` to be close to CI in more cases.
# Description
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.
Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.
# User-Facing Changes
`help commands` and `scope commands` will now use `description` or
`extra_description`
`usage`-> `description`
`extra_usage` -> `extra_description`
Breaking change in the plugin protocol:
In the signature record communicated with the engine.
`usage`-> `description`
`extra_usage` -> `extra_description`
The same rename also takes place for the methods on
`SimplePluginCommand` and `PluginCommand`
# Tests + Formatting

# After Submitting
- [ ] update plugin protocol doc

# Description
This grew quite a bit beyond its original scope, but I've tried to make
`$in` a bit more consistent and easier to work with.
Instead of the parser generating calls to `collect` and creating
closures, this adds `Expr::Collect` which just evaluates in the same
scope and doesn't require any closure.
When `$in` is detected in an expression, it is replaced with a new
variable (also called `$in`) and wrapped in `Expr::Collect`. During
eval, this expression is evaluated directly, with the input and with
that new variable set to the collected value.
Other than being faster and less prone to gotchas, it also makes it
possible to typecheck the output of an expression containing `$in`,
which is nice. This is a breaking change though, because of the lack of
the closure and because now typechecking will actually happen. Also, I
haven't attempted to typecheck the input yet.
The IR generated now just looks like this:
```gas
collect %in
clone %tmp, %in
store-variable $in, %tmp
# %out <- ...expression... <- %in
drop-variable $in
```
(where `$in` is the local variable created for this collection, and not
`IN_VARIABLE_ID`)
which is a lot better than having to create a closure and call `collect
--keep-env`, dealing with all of the capture gathering and allocation
that entails. Ideally we can also detect whether that input is actually
needed, so maybe we don't have to clone, but I haven't tried to do that
yet. Theoretically now that the variable is a unique one every time, it
should be possible to give it a type - I just don't know how to
determine that yet.
On top of that, I've also reworked how `$in` works in pipeline-initial
position. Previously, it was a little bit inconsistent. For example,
this worked:
```nushell
> 3 | do { let x = $in; let y = $in; print $x $y }
3
3
```
However, this causes a runtime variable not found error on the second
`$in`:
```nushell
> def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
Error: nu:🐚:variable_not_found
× Variable not found
╭─[entry #115:1:35]
1 │ def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
· ─┬─
· ╰── variable not found
╰────
```
I've fixed this by making the first element `$in` detection *always*
happen at the block level, so if you use `$in` in pipeline-initial
position anywhere in a block, it will collect with an implicit
subexpression around the whole thing, and you can then use that `$in`
more than once. In doing this I also rewrote `parse_pipeline()` and
hopefully it's a bit more straightforward and possibly more efficient
too now.
Finally, I've tried to make `let` and `mut` a lot more straightforward
with how they handle the rest of the pipeline, and using a redirection
with `let`/`mut` now does what you'd expect if you assume that they
consume the whole pipeline - the redirection is just processed as
normal. These both work now:
```nushell
let x = ^foo err> err.txt
let y = ^foo out+err>| str length
```
It was previously possible to accomplish this with a subexpression, but
it just seemed like a weird gotcha that you couldn't do it. Intuitively,
`let` and `mut` just seem to take the whole line.

# User-Facing Changes
- `$in` will behave more consistently with blocks and closures, since
the entire block is now just wrapped to handle it if it appears in the
first pipeline element
- `$in` no longer creates a closure, so what can be done within an
expression containing `$in` is less restrictive
- `$in` containing expressions are now type checked, rather than just
resulting in `any`. However, `$in` itself is still `any`, so this isn't
quite perfect yet
- Redirections are now allowed in `let` and `mut` and behave pretty much
how you'd expect
# Tests + Formatting
Added tests to cover the new behaviour.
# After Submitting
- [ ] release notes (definitely breaking change)
# Description
Add `README.md` files to each crate in our workspace (-plugins) and also
include it in the `lib.rs` documentation for <docs.rs> (if there is no
existing `lib.rs` crate documentation)
In all new README I added the defensive comment that the crates are not
considered stable for public consumption. If necessary we can adjust
this if we deem a crate useful for plugin authors.
