# Description
Because the IR compiler was previously optional, compile errors were not
treated as fatal errors, and were just logged like parse warnings are.
This unfortunately meant that if a user encountered a compile error,
they would see "Can't evaluate block in IR mode" as the actual error in
addition to (hopefully) logging the compile error.
This changes compile errors to be treated like parse errors so that they
show up as the last error, helping users understand what's wrong a
little bit more easily.
Fixes#14333.
# User-Facing Changes
- Shouldn't see "Can't evaluate block in IR mode"
- Should only see compile error
- No evaluation should happen
# Tests + Formatting
Didn't add any tests specifically for this, but it might be good to have
at least one that checks to ensure the compile error shows up and the
"can't evaluate" error does not.
# Description
I was reading through the documentation yesterday, when I stumbled upon
[this
section](https://www.nushell.sh/book/pipelines.html#behind-the-scenes)
explaining how command output is formatted using the `table` command. I
was surprised that this section didn't mention the `display_output`
hook, so I took a look in the code and was shocked to discovered that
the documentation was correct, and the `table` command _is_
automatically applied to printed pipelines.
This auto-tabling has two ramifications for the `display_output` hook:
1. The `table` command is called on the output of a pipeline after the
`display_output` has run, even if `display_output` contains the table
command. This means each pipeline output is roughly equivalent to the
following (using `ls` as an example):
```nushell
ls | do $config.hooks.display_output | table
```
2. If `display_output` returns structured data, it will _still_ be
formatted through the table command.
This PR removes the auto-table when the `display_output` hook is set.
The auto-table made sense before `display_output` was introduced, but to
me, it now seems like unnecessary "automagic" which can be accomplished
using existing Nushell features.
This means that you can now pull back the curtain a bit, and replace
your `display_output` hook with an empty closure
(`$env.config.hooks.display_output = {||}`, setting it to null retains
the previous behavior) to see the values printed normally without the
table formatting. I think this is a good thing, and makes it easier to
understand Nushell fundamentals.
It is important to note that this PR does not change how `print` and
other commands (well, specifically only `watch`) print out values. They
continue to use `table` with no arguments, so changing your
config/`display_output` hook won't affect what `print`ing a value does.

# User-Facing Changes
Pipelines are no longer automatically formatted using the `table`
command. Instead, the `display_output` hook is used to format pipeline
output. Most users should see no impact, as the default `display_output`
hook already uses the `table` command.

# Description
In certain situations, we had ansi bleed on the right prompt. This PR
fixes that by prefixing the right prompt with an ansi reset `\x1b[0m`.
This PR also adds some --log-level warn logging so we can see the ansi
escapes that form the prompts.
Closes https://github.com/nushell/nushell/issues/14268
Trying to reduce lint allows either by checking if they are former false
positives or by fixing the underlying warning.
- **Remove dead `allow(dead_code)`**
- **Remove recursive dead code**
- **Remove dead code**
- **Move test only functions to test module**
The unit tests that use them, themselves are somewhat sus in that they
mock the usage and not test specificly used methods of the
implementation, so there is a risk for divergence
- **Remove `clippy::uninit_vec` allow.**
May have been a false positive, or the impl has changed somewhat.
We certainly want to look at the unsafe code here to vet for
correctness.
# 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
Turns out there are duplicate conversion functions: `as_i64` and
`as_f64`. In most cases, these can be replaced with `as_int` and
`as_float`, respectively.
With #14083 a dependency on `test-case` was introduced, we already
depend on the more exp(a/e)nsive `rstest` for our macro-based test case
generation (with fixtures on top)
To save on some compilation for proc macros unify to `rstest`
I feel like the limitations on what can be bound are too strict.
if an app _does_ support the Kitty keyboard protocol (Neovim,
Reedline), I can map the function keys (F27-F35 as listed below).
In Reedline everything works perfectly. The issue is for some reason we
limit the keys that can be bound in Nushell, so I am unable to do that.

This PR fixes the quoting and escaping of column names in `to nuon`.
Before the PR, column names with quotes inside them would get quoted,
but not escaped:
```nushell
> { 'a"b': 2 } | to nuon
{ "a"b": 2 }
> { 'a"b': 2 } | to nuon | from nuon
Error: × error when loading nuon text

╰────
Error: × error when parsing
╭────
1 │ [["a"b"]; [2], [3]]
· ┬
· ╰── Unexpected end of code.
╰────
```
After this PR, the quote is escaped properly:
```nushell
> { 'a"b': 2 } | to nuon
{ "a\"b": 2 }
> { 'a"b': 2 } | to nuon | from nuon
╭─────┬───╮
│ a"b │ 2 │
╰─────┴───╯
> [['a"b']; [2] [3]] | to nuon
[["a\"b"]; [2], [3]]
> [['a"b']; [2] [3]] | to nuon | from nuon
╭─────╮
│ a"b │
├─────┤
│ 2 │
│ 3 │
╰─────╯
```
The cause of the issue was that `to nuon` simply wrapped column names in
`'"'` instead of calling `escape_quote_string`.
As part of this change, I also moved the functions related to quoting
(`needs_quoting` and `escape_quote_string`) into `nu-utils`, since
previously they were defined in very ad-hoc places (and, in the case of
`escape_quote_string`, it was defined multiple times with the same
body!).

# Description
This is mainly https://github.com/nushell/nushell/pull/13450 (which got
reverted). Additionally:
- always clear IDs on import, disallow specifying IDs when piping
- added extra tests
- create backup of the history
# User-Facing Changes
New command: `history import`
# Tests + Formatting
Added mostly integration tests and a few smaller unit tests.
# Description
This PR closes#14137 and allows the display hook to be set on byte
streams. So, with a hook like this below.
```nushell
display_output: {
metadata access {|meta| match $meta.content_type? {
"application/x-nuscript" | "application/x-nuon" | "text/x-nushell" => { nu-highlight },
"application/json" => { ^bat --language=json --color=always --style=plain --paging=never },
_ => {},
}
} | table
}
```
You could type `open toolkit.nu` and the text of toolkit.nu would be
highlighted by nu-highlight. This PR also changes the way content-type
is assigned with `open`. Previously it would only assign it if `--raw`
was specified.
Lastly, it changes the `is_external()` function to only say
`ByteStreamSource::Child`'s are external instead of both Child and
`ByteStreamSource::File`. Again, this was to allow the hook to function
properly. I'm not sure what negative ramifications changing
`is_external()` could have, but there may be some?

# Description
Adds back the `to_ascii_lowercase` deleted in #13802. Also fixes the
error messages having the lowercased value instead of the original

# Description
Adds a simple command for importing history between different file
formats. It essentially opens the history of the format opposite of the
one currently selected, and writes new items to the current history. It
also supports piping, because why not.
As more history backends are added, this may need to be extended -
either make the source explicit, or autodetect based on existing files.
For now it should be good though.
This should replace some of the work-arounds mentioned in
https://github.com/nushell/nushell/issues/9403.
I suspect it will have at least one problem:
https://github.com/nushell/nushell/issues/9403 mentions the history file
might be locked on Windows. That being said, I was able to successfully
import plaintext history into sqlite on Linux, so the command should be
functional at least in that environment.
The locking issue could be solved later by plumbing reedline history to
the command (so that it doesn't have to reopen it). But first, I want to
get some general input on the approach.
# User-Facing Changes
New command: `history import`
# Tests + Formatting
There's a unit test, but didn't add a proper integration test yet. Not
entirely sure how - I see there's the `nu!` macro for that, but not sure
how feasible it's to inspect history generated by commands ran that way.
Could use a hint.2
# Description
This PR standardizes updates to the config through a new
`UpdateFromValue` trait. For now, this trait is private in case we need
to make changes to it.
Note that this PR adds some additional `ShellError` cases to create
standard error messages for config errors. A follow-up PR will move
usages of the old error cases to these new ones. This PR also uses
`Type::custom` in lots of places (e.g., for string enums). Not sure if
this is something we want to encourage.
# User-Facing Changes
Should be none.
# Description
Currently there is a bit of chaos regarding construction of history file
paths. Various pieces of code across a number of crates reimplement the
same/similar logic:
- There is `get_history_path`, but it requires a directory parameter (it
really just joins it with a file name).
- Some places use a const for the directory parameter, others use a
string literal - in all cases the value seems to be `"nushell"`.
- Some places assume the `"nushell"` value, other plumb it down from
close to the top of the call stack.
- Some places use a constant for history file names while others assume
it.
This PR tries to make it so that the history/config path format is
defined in a single places and so dependencies on it are easier to
follow:
- It removes `get_history_path` and adds a `file_path` method to
`HistoryConfig` instead (an extra motivation being, this is a convenient
place that can be used from all creates that need a history file path)
- Adds a `nu_config_dir` function that returns the nushell configuration
directory.
- Updates existing code to rely on the above, effectively removing
duplicate uses of `"nushell"` and `NUSHELL_FOLDER` and assumptions about
file names associated with different history formats

# Description
This pull request enhances the `add_parsed_keybinding` function to
provide greater flexibility in specifying keycodes for keybindings in
Nushell. Previously, the function only supported specifying keycodes
directly through character notation (e.g., `char_e` for the character
`e`). This limited users to a small set of keybindings, especially in
scenarios where specific non-English characters were needed.
With this new version, users can also specify characters using their
Unicode codes, such as `char_u003B` for the semicolon (`;`), providing a
more flexible approach to customization, for example like this:
```nushell
{
name: move_to_line_end_or_take_history_hint
modifier: shift
keycode: char_u003B # char_;
mode: vi_normal
event: {
until: [
{ send: historyhintcomplete }
{ edit: movetolineend }
]
}
}
```
# User-Facing Changes
Added support for specifying keycodes using Unicode codes, e.g.,
char_u002C (comma - `,`):
```nushell
{
name: <command_name>, # name of the command
modifier: none, # key modifier
keycode: char_u002C, # Unicode code for the comma (',')
mode: vi_normal, # mode in which this binding should work
event: {
send: <action> # action to be performed
}
}
```
This pr does two optimization for the completer:
- Switch `sort_by` to `sort_unstable_by` on `sort_completions` function
since it reduces memory allocation and the orders of the identical
completions are not matter.
- Change `prefix` type from `Vec<u8>` to `&[u8]` to reduce cloning and
memory.
# Description
* Fixes missing closing parenthesis on `not-in` completion
Also tweaks the others to give them consistent capitalization and
punctuation:
* First word initial-case, other words lower-case
* Exception - Initial-case for "also known as" after slash or inside
parens
* No closing period for any completion help
* Word-smithing on others. E.g., "Mod" is technically "Remainder"

Updates Ctrl+p to open the ide_completion menu and otherwise advance to
the "previous" menu item.
Ctrl+n opens the ide_completion_menu and subsequently advances to the
"next" menu item. Ctrl+p should share this behavior for the "previous"
menu item. See nushell/nushell#13946 for detailed discussion.
Tested by building and running nushell without a custom config, falling
back to this default config.

# Description
This PR drastically improves startup times of Nushell by only parsing a
single submodule of the Standard Library that provides the `banner` and
`pwd` commands. All other Standard Library commands and submodules are
parsed when imported by the user. This cuts startup times by more than
60%.
At the moment, we have stopped adding to `std-lib` because every
addition adds a small amount to the Nushell startup time.
With this change, we should once again be able to allow new
functionality to be added to the Standard Library without it impacting
`nu` startup times.
# User-Facing Changes
* Nushell now starts about 60% faster
* Breaking change: The `dirs` (Shells) aliases will return a warning
message that it will not be auto-loaded in the following release, along
with instructions on how to restore it (and disable the message)
* The `use std <submodule> *` syntax is available for convenience, but
should be avoided in scripts as it parses the entire `std` module and
all other submodules and places it in scope. The correct syntax to
*just* load a submodule is `use std/<submodule> *` (asterisk optional).
The slash is important. This will be documented.
* `use std *` can be used for convenience to load all of the library but
still incurs the full loading-time.
* `std/dirs`: Semi-breaking change. The `dirs` command replaces the
`show` command. This is more in line with the directory-stack
functionality found in other shells. Existing users will not be impacted
by this as the alias (`shells`) remains the same.
* Breaking-change: Technically a breaking change, but probably only
impacts maintainers of `std`. The virtual path for the standard library
has changed. It could previously be imported using its virtual path (and
technically, this would have been the correct way to do it):
```nu
use NU_STDLIB_VIRTUAL_DIR/std
```
The path is now simply `std/`:
```nu
use std
```
All submodules have moved accordingly.
# Timings
Comparisons below were made:
* In a temporary, clean config directory using `$env.XDG_CONFIG_HOME =
(mktemp -d)`.
* `nu` was run with a release build
* `nu` was run one time to generate the default `config.nu` (etc.) files
- Otherwise timings would include the user-prompt
* The shell was exited and then restarted several times to get timing
samples
(Note: Old timings based on 0.97 rather than 0.98, but in the range of
being accurate)

*These last two timings point to the opportunity for further
optimization (see comment in thread below (will link once I write it).*
# Implementation details for future maintenance
* `use std banner` is a ridiculously deceptive call. That call parses
and imports *all* of `std` into scope. Simply replacing it with `use
std/core *` is essentially what saves ~14-15ms. This *only* imports the
submodule with the `banner` and `pwd` commands.
* From the code-comments, the reason that `NU_STDLIB_VIRTUAL_DIR` was
used as a prefix was so that there wouldn't be an issue if a user had a
`./std/mod.nu` in the current directory. This does **not** appear to be
an issue. After removing the prefix, I tested with both a relative
module as well as one in the `$env.NU_LIB_DIRS` path, and in all cases
the *internal* `std` still took precedence.
* By removing the prefix, users can now `use std` (and variants) without
requiring that it already be parsed and in scope.
* In the next release, we'll stop autoloading the `dirs` (shells)
functionality. While this only costs an additional 1-1.5ms, I think it's
better moved to the `config.nu` where the user can optionally remove it.
The main reason is its use of aliases (which have also caused issues) -
The `n`, `p`, and `g` short-commands are valuable real-estate, and users
may want to map these to something else.
For this release, there's an `deprecated_dirs` module that is still
autoloaded. As with the top-level commands, use of these will give a
deprecation warning with instructions on how to handle going forward.
To help with this, moved the aliases to their own submodule inside the
`dirs` module.
* Also sneaks in a small change where the top-level `dirs` command is
now the replacement for `dirs show`
* Fixed a double-import of `assert` in `dirs.nu`
* The `show_banner` step is replaced with simply `banner` rather than
re-importing it.
* A `virtual_path` may now be referenced with either a forward-slash or
a backward-slash on Windows. This allows `use std/<submodule>` to work
on all platforms.
# Performance side-notes:
* Future parsing and/or IR improvements should improve performance even
further.
* While the existing load time penalty of `std-lib` was not noticeable
on many systems, Nushell runs on a wide-variety of hardware and OS
platforms. Slower platforms will naturally see a bigger jump in
performance here. For users starting multiple Nushell sessions
frequently (e.g., `tmux`, Zellij, `screen`, et. al.) it is recommended
to keep total startup time (including user configuration) under ~250ms.
# Tests + Formatting
* All tests are green
* Updated tests:
- Removed the test that confirmed that `std` was loaded (since we
don't).
- Removed the `shells` test since it is not autoloaded. Main `dirs.nu`
functionality is tested through `stdlib-test`.
- Many tests assumed that the library was fully loaded, because it was
(even though we didn't intend for it to be). Fixed those tests.
- Tests now import only the necessary submodules (e.g., `use
std/assert`, rather than `use std assert`)
- Some tests *thought* they were loading `std/log`, but were doing so
improperly. This was masked by the now-fixed "load-everything-into-scope
bug". Local CI would pass due the `$env.NU_LOG_<...>` variables being
inherited from the calling process, but would fail in the "clean" GitHub
CI environment. These tests have also been fixed.
* Added additional tests for the changes
# After Submitting
Will update the Standard Library doc page
# Description
Title says it all, changes `EngineState::get_env_var` to return a
`Option<&'a Value>` instead of an owned `Option<Value>`. This avoids
some unnecessary clones.
I also made a similar change to the `PluginExecutionContext` trait.
# 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
This PR tries to allow the `ls` command to use multiple threads if so
specified. The reason why you'd want to use threads is if you notice
`ls` taking a long time. The one place I see that happening is from WSL.
I'm not sure how real-world this test is but you can see that this
simple `ls` of a folder with length takes a while 9366 ms. I've run this
test many times and it ranges from about 15 seconds to about 10 seconds.
But with the `--threads` parameter, it takes less time, 2744ms in this
screenshot.
The only way forward I could find was to _always_ use threading and
adjust the number of threads based on if the user provides a flag. That
seemed the easiest way to do it after applying @devyn's interleave
advice.
No feelings hurt if this doesn't land. It's more of an experiment but I
think it has potential.
