# Description
Light refactoring of `send_request `in `client.rs`. In the end there are
more lines but now the logic is more concise and facilitates adding new
conditions in the future. Unit tests ran fine and I tested a few cases
manually.
Cool project btw, I'll be using nushell from now on.
# Description
This pr addresses the comment:
https://github.com/nushell/nushell/issues/11791#issuecomment-2308384155
It's caused by if the last row have a very different format to the first
row, the value of `end_char` will exceed the `line_char_boundaries`.
Adding a guard for it should avoid such panic.
# User-Facing Changes
The following code should no longer panic:
```shell
"nu_plugin_highlight = '1.2.2+0.97.1' # A nushell plugin for syntax highlighting
trace_nu_plugin = '0.3.1' # A wrapper to trace Nu plugins
nu_plugin_bash_env = '0.13.0' # Nu plugin bash-env
nu_plugin_from_sse = '0.4.0' # Nushell plugin to convert a HTTP server sent event stream to structured data
... and 90 crates more (use --limit N to see more)" | detect columns -n --guess
```
# Tests + Formatting
Added 1 test.
# Description
This changes the behavior of `tee` to be more transparent when given a
value that isn't a list or range. Previously, anything that wasn't a
byte stream would converted to a list stream using the iterator
implementation, which led to some surprising results. Instead, now, if
the value is a string or binary, it will be treated the same way a byte
stream is, and the output of `tee` is a byte stream instead of the
original value. This is done so that we can synchronize with the other
thread on collect, and potentially capture any error produced by the
closure.
For values that can't be converted to streams, the closure is just run
with a clone of the value instead on another thread. Because we can't
wait for the other thread, there is no way to send an error back to the
original thread, so instead it's just written to stderr using
`report_error_new()`.
There are a couple of follow up edge cases I see where byte streams
aren't necessarily treated exactly the same way strings are, but this
should mostly be a good experience.
Fixes#13489.
# User-Facing Changes
Breaking change.
- `tee` now outputs and sends string/binary stream for string/binary
input.
- `tee` now outputs and sends the original value for any other input
other than lists/ranges.
# Tests + Formatting

# 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

# Description
Closes#13677
Remove the command `str deunicode`, as it has a narrow application, is
loosely defined by the data provided by the `deunicode` crate and thus a
stabilization liability post-1.0.
Furthermore the data to perform the look-up is quite substantial.
Removing the command and the `deunicode` dependency saves 0.9 MB of
binary data in release mode (~ 2% of total)
(checked via `cargo bloat --release` for a linux x86 build)
# User-Facing Changes
The `str deunicode` command recently added in #13270 is gone
Mistakes have been made. I forgot about a bunch of `todo`s in the helper
functions. So, this PR replaces them with proper errors. It also adds
tests for parse-time evaluation, because one `todo` I missed was in a
`run_const` function.

Based on the discussion in #13419.
## Description
Reworks the `decode`/`encode` commands by adding/changing the following
bases:
- `base32`
- `base32hex`
- `hex`
- `new-base64`
The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.
All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.
## Example usage
```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```
```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000: 74 65 73 74 test
```
## User-Facing Changes
- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.
# 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

# Description
The previous behaviour of `into record` on lists was to create a new
record with each list index as the key. This was not very useful for
creating meaningful records, though, and most people would end up using
commands like `headers` or `transpose` to turn a list of keys and values
into a record.
This PR changes that instead to do what I think the most ergonomic thing
is, and instead:
- A list of records is merged into one record.
- A list of pairs (two element lists) is folded into a record with the
first element of each pair being the key, and the second being the
value.
The former is just generally more useful than having to use `reduce`
with `merge` for such a common operation, and the latter is useful
because it means that `$a | zip $b | into record` *just works* in the
way that seems most obvious.
Example:
```nushell
[[foo bar] [baz quux]] | into record # => {foo: bar, baz: quux}
[{foo: bar} {baz: quux}] | into record # => {foo: bar, baz: quux}
[foo baz] | zip [bar quux] | into record # => {foo: bar, baz: quux}
```
The support for range input has been removed, as it would no longer
reflect the treatment of an equivalent list.
The following is equivalent to the old behavior, in case that's desired:
```
0.. | zip [a b c] | into record # => {0: a, 1: b, 2: c}
```
# User-Facing Changes
- `into record` changed as described above (breaking)

# Description
This PR is meant to provide a more helpful error message when using http
get and the content type can't be parsed.
### Before
### After
The span isn't perfect but there's no way to get the span of the content
type that I can see.
In the middle of fixing this error, I also discovered how to fix the
problem in general. Since you can now see the error message complaining
about double quotes (char 22 at position 0. 22 hex is `"`). The fix is
just to remove all the double quotes from the content_type and then you
get this.
### After After
The discussion on Discord about this is that `--raw` or
`--ignore-errors` should eat this error and it "just work" as well as
default to text or binary when the mime parsing fails. I agree but this
PR does not implement that.

# Description
Fixes Issue #13477
This adds a check to see if a user is trying to invoke a
(non-executable) file as a command and returns a helpful error if so.
EDIT: this will not work on Windows, and is arguably not relevant there,
because of the different semantics of executables. I think the
equivalent on Windows would be if a user tries to invoke `./foo`, we
should look for `foo.exe` or `foo.bat` in the directory and recommend
that if it exists.
# User-Facing Changes
When a user invokes an unrecognized command that is the path to an
existing file, the error used to say:
`{name} is neither a Nushell built-in or a known external command`
This PR proposes to change the message to:
`{name} refers to a file that is not executable. Did you forget to to
set execute permissions?`
# Tests + Formatting
Ran cargo fmt, clippy and test on the workspace.
EDIT: added test asserting the new behavior
# Description
Something I meant to add a long time ago. We currently don't have a
convenient way to print raw binary data intentionally. You can pipe it
through `cat` to turn it into an unknown stream, or write it to a file
and read it again, but we can't really just e.g. generate msgpack and
write it to stdout without this. For example:
```nushell
[abc def] | to msgpack | print --raw
```
This is useful for nushell scripts that will be piped into something
else. It also means that `nu_plugin_nu_example` probably doesn't need to
do this anymore, but I haven't adjusted it yet:
```nushell
def tell_nushell_encoding [] {
print -n "\u{0004}json"
}
```
This happens to work because 0x04 is a valid UTF-8 character, but it
wouldn't be possible if it were something above 0x80.
`--raw` also formats other things without `table`, I figured the two
things kind of go together. The output is kind of like `to text`.
Debatable whether that should share the same flag, but it was easier
that way and seemed reasonable.

# Description
When using a format string, `into datetime` would disallow an `int` even
when it logically made sense. This was mainly a problem when attempting
to convert a Unix epoch to Nushell `datetime`. Unix epochs are often
stored or returned as `int` in external data sources.
```nu
1722821463 | into datetime -f '%s'
Error: nu:🐚:only_supports_this_input_type
× Input type not supported.
╭─[entry #3:1:1]

· ─────┬──── ──────┬──────
· │ ╰── only string input data is supported
· ╰── input type: int
╰────
```
While the solution was simply to `| to text` the `int`, this PR handles
the use-case automatically.
Essentially a ~5 line change that just moves the current parsing to a
closure that is called for both Strings and Ints-converted-to-Strings.

# Description
Minor nitpicks, but the `random int` help and examples were a bit
ambiguous in several aspects. Updated to clarify that:
* An unconstrained `random int` returns a non-negative integer. That is,
the smallest potential value is 0. Technically integers include negative
numbers as well, and `random int` will never return one unless you pass
it a range with a negative lower-bound.
* To that end, changed the final example to demonstrate a negative
lower-bound.
* The range is inclusive. While most people would probably assume this,
the changes make this explicit in the examples and argument description.

moved into #13498 feel somewhat arbitrary, I also raised
https://github.com/rust-lang/rust-clippy/issues/13188 as the nightly
`byte_char_slices` would require either a global allow or otherwise a
ton of granular allows or possibly confusing bytestring literals.
# Description
Fixes: #13260
When user run a command like this:
```nushell
$env.FOO = " New";
$env.BAZ = " New Err";
do -i {nu -n -c 'nu --testbin echo_env FOO; nu --testbin echo_env_stderr BAZ'} | save -a -r save_test_22/log.txt
```
`save` command sinks the output of previous commands' stderr output. I
think it should be `stderr`.
# User-Facing Changes
```nushell
$env.FOO = " New";
$env.BAZ = " New Err";
do -i {nu -n -c 'nu --testbin echo_env FOO; nu --testbin echo_env_stderr BAZ'} | save -a -r save_test_22/log.txt
```
The command will output ` New Err` to stderr.
# Tests + Formatting

# Description
This makes assignment operations and `const` behave the same way `let`
and `mut` do, absorbing the rest of the pipeline.
Changes the lexer to be able to recognize assignment operators as a
separate token, and then makes the lite parser continue to push spans
into the same command regardless of any redirections or pipes if an
assignment operator is encountered. Because the pipeline is no longer
split up by the lite parser at this point, it's trivial to just parse
the right hand side as if it were a subexpression not contained within
parentheses.
# User-Facing Changes
Big breaking change. These are all now possible:
```nushell
const path = 'a' | path join 'b'
mut x = 2
$x = random int
$x = [1 2 3] | math sum
$env.FOO = random chars
```
In the past, these would have led to (an attempt at) bare word string
parsing. So while `$env.FOO = bar` would have previously set the
environment variable `FOO` to the string `"bar"`, it now tries to run
the command named `bar`, hence the major breaking change.
However, this is desirable because it is very consistent - if you see
the `=`, you can just assume it absorbs everything else to the right of
it.
# Tests + Formatting
Added tests for the new behaviour. Adjusted some existing tests that
depended on the right hand side of assignments being parsed as
barewords.

# Description
The current version of `stor` forces stripping ansi code coloring from
all the strings.
In this PR, I propose to keep strings unchanged.
The logic behind the proposed changes was best described in the
[discord](https://discord.com/channels/601130461678272522/601130461678272524/1266387441074442272):
<img width="773" alt="image"
src="https://github.com/user-attachments/assets/063cdebd-684f-46f1-aca1-faeb4827723d">
with proposed changes we can store colored output:
```
stor reset; stor create --table-name test --columns {a: str};
ls | table | {a: $in} | stor insert --table-name test | null;
stor open | query db 'select a from test' | get a.0
```

src="https://github.com/user-attachments/assets/8f062808-18fc-498b-a77e-a118f6b9953a">
# User-Facing Changes
If one was using `stor` together with ansi colored input, and then was
querying `stor` with search operations, they might break. But I don't
think that it is a big problem, as one will just need to use `ansi
reset` before storing data.
# Tests + Formatting
Tests are okay.

# User-Facing Changes
It's a breaking change because we have switched the position of
`<initial>` and `<closure>`, after the change, initial value will be
optional. So it's possible to do something like this:
```nushell
> let f = {|fib = [0, 1]| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
> generate $f | first 5
╭───┬───╮
│ 0 │ 0 │
│ 1 │ 1 │
│ 2 │ 1 │
│ 3 │ 2 │
│ 4 │ 3 │
╰───┴───╯
```
It will also raise error if user don't give initial value, and the
closure don't have default parameter.
```nushell
❯ let f = {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
❯ generate $f
Error: × The initial value is missing

# Description
Following from #13377, this PR refactors the related `window` command.
In the case where `window` should behave exactly like `chunks`, it now
reuses the same code that `chunks` does. Otherwise, the other cases have
been rewritten and have resulted in a performance increase:
| window size | stride | old time (ms) | new time (ms) |
| -----------:| ------:| -------------:| -------------:|
| 20 | 1 | 757 | 722 |
| 2 | 1 | 364 | 333 |
| 1 | 1 | 343 | 293 |
| 20 | 20 | 90 | 63 |
| 2 | 2 | 215 | 175 |
| 20 | 30 | 74 | 60 |
| 2 | 4 | 141 | 110 |
# User-Facing Changes
`window` will now error if the window size or stride is 0, which is
technically a breaking change.
# 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.
- closes#13137
# 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

# Description
Before this change `default` would dive into lists and replace `null`
elements with the default value.
Therefore there was no easy way to process `null|list<null|string>`
input and receive `list<null|string>`
(IOW to apply the default on the top level only).
However it's trivially easy to apply default values to list elements
with the `each` command:
```nushell
[null, "a", null] | each { default "b" }
```
So there's no need to have this behavior in `default` command.
# User-Facing Changes

the default value.
# Tests + Formatting
Added a couple of tests for the new (and old) behavior.
# After Submitting

# Description
The name of the `group` command is a little unclear/ambiguous.
Everything I look at it, I think of `group-by`. I think `chunks` more
clearly conveys what the `group` command does. Namely, it divides the
input list into chunks of a certain size. For example,
[`slice::chunks`](https://doc.rust-lang.org/std/primitive.slice.html#method.chunks)
has the same name. So, this PR adds a new `chunks` command to replace
the now deprecated `group` command.
The `chunks` command is a refactored version of `group`. As such, there
is a small performance improvement:
```nushell
# $data is a very large list
> bench { $data | chunks 2 } --rounds 30 | get mean
474ms 921µs 190ns
# deprecation warning was disabled here for fairness
> bench { $data | group 2 } --rounds 30 | get mean
592ms 702µs 440ns
> bench { $data | chunks 200 } --rounds 30 | get mean
374ms 188µs 318ns
> bench { $data | group 200 } --rounds 30 | get mean
481ms 264µs 869ns
> bench { $data | chunks 1 } --rounds 30 | get mean
642ms 574µs 42ns
> bench { $data | group 1 } --rounds 30 | get mean
981ms 602µs 513ns
```

This adds tracing for each individual instruction to the `Debugger`
trait. Register contents can be inspected both when entering and leaving
an instruction, and if an instruction produced an error, a reference to
the error is also available. It's not the full `EvalContext` but it's
most of the important parts for getting an idea of what's going on.
Added support for all of this to the `Profiler` / `debug profile` as
well, and the output is quite incredible - super verbose, but you can
see every instruction that's executed and also what the result was if
it's an instruction that has a clearly defined output (many do).
# User-Facing Changes
- Added `--instructions` to `debug profile`, which adds the `pc` and
`instruction` columns to the output.
- `--expr` only works in AST mode, and `--instructions` only works in IR

# Description
Just a quick one, but `List(Any)` has to come before `Table`, because
`List(Any)` is a valid match for `Table`, so it will choose `Table`
output even if the input was actually `List(Any)`. I ended up removing
`Table` because it's just not needed at all anyway.
Though, I'm not really totally sure this is correct - I think the parser
should probably actually just have some idea of what the more specific
type is, and choose the most specific type match, rather than just doing
it in order. I guess this will result in the output just always being
`List(Any)` for now. Still better than a bad typecheck error
# User-Facing Changes
Fixes the following contrived example:
```nushell
def foo []: nothing -> list<int> {
seq 1 10 | # list<int>
each { |n| $n * 20 } | # this causes the type to become list<any>
take until { |x| $x < 10 } } # table is first, so now this is type table
# ...but table is not compatible with list<int>
}

# Description
Allows `Stack` to have a modified local `Config`, which is updated
immediately when `$env.config` is assigned to. This means that even
within a script, commands that come after `$env.config` changes will
always see those changes in `Stack::get_config()`.
Also fixed a lot of cases where `engine_state.get_config()` was used
even when `Stack` was available.
Closes#13324.
# User-Facing Changes
- Config changes apply immediately after the assignment is executed,
rather than whenever config is read by a command that needs it.
- Potentially slower performance when executing a lot of lines that
change `$env.config` one after another. Recommended to get `$env.config`
into a `mut` variable first and do modifications, then assign it back.
- Much faster performance when executing a script that made
modifications to `$env.config`, as the changes are only parsed once.

Add a few more options to `view ir` for finding blocks, which I found
myself wanting while trying to trace through the generated code.
If we end up adding support for plugins to call commands that are in
scope by name, this will also make it possible for
`nu_plugin_explore_ir` to just step through IR automatically (by passing
the block/decl ids) without exposing too many internals. With that I
could potentially add keys that allow you to step in to closures or
decls with the press of a button, just by calling `view ir --json`
appropriately.
# User-Facing Changes
- `view ir` can now take names of custom commands that are in scope.
- integer arguments are treated as block IDs, which sometimes show up in
IR (closure, block, row condition literals).
- `--decl-id` provided to treat the argument as a decl ID instead, which
is also sometimes necessary to access something that isn't in scope.
# Description
Fix `view ir` to use `Signature::build()` rather than `new()`, which is
required for `--help` to work. Also add `Category::Debug`, as that's
most appropriate.
# Description
This PR adds an internal representation language to Nushell, offering an
alternative evaluator based on simple instructions, stream-containing
registers, and indexed control flow. The number of registers required is
determined statically at compile-time, and the fixed size required is
allocated upon entering the block.
Each instruction is associated with a span, which makes going backwards
from IR instructions to source code very easy.
Motivations for IR:
1. **Performance.** By simplifying the evaluation path and making it
more cache-friendly and branch predictor-friendly, code that does a lot
of computation in Nushell itself can be sped up a decent bit. Because
the IR is fairly easy to reason about, we can also implement
optimization passes in the future to eliminate and simplify code.
2. **Correctness.** The instructions mostly have very simple and
easily-specified behavior, so hopefully engine changes are a little bit
easier to reason about, and they can be specified in a more formal way
at some point. I have made an effort to document each of the
instructions in the docs for the enum itself in a reasonably specific
way. Some of the errors that would have happened during evaluation
before are now moved to the compilation step instead, because they don't
make sense to check during evaluation.
3. **As an intermediate target.** This is a good step for us to bring
the [`new-nu-parser`](https://github.com/nushell/new-nu-parser) in at
some point, as code generated from new AST can be directly compared to
code generated from old AST. If the IR code is functionally equivalent,
it will behave the exact same way.
4. **Debugging.** With a little bit more work, we can probably give
control over advancing the virtual machine that `IrBlock`s run on to
some sort of external driver, making things like breakpoints and single
stepping possible. Tools like `view ir` and [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir) make it easier than
before to see what exactly is going on with your Nushell code.
The goal is to eventually replace the AST evaluator entirely, once we're
sure it's working just as well. You can help dogfood this by running
Nushell with `$env.NU_USE_IR` set to some value. The environment
variable is checked when Nushell starts, so config runs with IR, or it
can also be set on a line at the REPL to change it dynamically. It is
also checked when running `do` in case within a script you want to just
run a specific piece of code with or without IR.
# Example
```nushell
view ir { |data|
mut sum = 0
for n in $data {
$sum += $n
}
$sum
}
```
```gas
# 3 registers, 19 instructions, 0 bytes of data
0: load-literal %0, int(0)
1: store-variable var 904, %0 # let
2: drain %0
3: drop %0
4: load-variable %1, var 903
5: iterate %0, %1, end 15 # for, label(1), from(14:)
6: store-variable var 905, %0
7: load-variable %0, var 904
8: load-variable %2, var 905
9: binary-op %0, Math(Plus), %2
10: span %0
11: store-variable var 904, %0
12: load-literal %0, nothing
13: drain %0
14: jump 5
15: drop %0 # label(0), from(5:)
16: drain %0
17: load-variable %0, var 904
18: return %0
```
# Benchmarks
All benchmarks run on a base model Mac Mini M1.
## Iterative Fibonacci sequence
This is about as best case as possible, making use of the much faster
control flow. Most code will not experience a speed improvement nearly
this large.
```nushell
def fib [n: int] {
mut a = 0
mut b = 1
for _ in 2..=$n {
let c = $a + $b
$a = $b
$b = $c
}
$b
}
use std bench
bench { 0..50 | each { |n| fib $n } }
```

[random-bytes.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/random-bytes.nu)
I got pretty random results out of this benchmark so I decided not to
include it. Not clear why.
# User-Facing Changes
- IR compilation errors may appear even if the user isn't evaluating
with IR.
- IR evaluation can be enabled by setting the `NU_USE_IR` environment
variable to any value.
- New command `view ir` pretty-prints the IR for a block, and `view ir
--json` can be piped into an external tool like [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir).
# Tests + Formatting
All tests are passing with `NU_USE_IR=1`, and I've added some more eval
tests to compare the results for some very core operations. I will
probably want to add some more so we don't have to always check
`NU_USE_IR=1 toolkit test --workspace` on a regular basis.
# After Submitting
- [ ] release notes
- [ ] further documentation of instructions?
- [ ] post-release: publish `nu_plugin_explore_ir`
GOOD CATCH.............................................................
SORRY
I've added a test to catch regression just in case.
close#13319

# Description
This PR introduces a new `Signals` struct to replace our adhoc passing
around of `ctrlc: Option<Arc<AtomicBool>>`. Doing so has a few benefits:
- We can better enforce when/where resetting or triggering an interrupt
is allowed.
- Consolidates `nu_utils::ctrl_c::was_pressed` and other ad-hoc
re-implementations into a single place: `Signals::check`.
- This allows us to add other types of signals later if we want. E.g.,
exiting or suspension.
- Similarly, we can more easily change the underlying implementation if
we need to in the future.
- Places that used to have a `ctrlc` of `None` now use
`Signals::empty()`, so we can double check these usages for correctness
in the future.
# Description
fixed#12699
When bare dates or naive times are specified in toml files, `from toml`
returns invalid dates or times.
This PR fixes the problem to correctly handle toml datetime.
The current version command returns the default datetime
(`chrono::DateTime::default()`) if the datetime parse fails. However, I
felt that this behavior was a bit unfriendly, so I changed it to return
`Value::string`.
# User-Facing Changes
The command returns a date with default time and timezone if a bare date
is specified.
```
~/Development/nushell> "dob = 2023-05-27" | from toml
╭─────┬────────────╮
│ dob │ a year ago │

Sat, 27 May 2023 00:00:00 +0000 (a year ago)
~/Development/nushell>
```
If a bare time is given, a time string is returned.
```

# Description
Refactors `help operators` so that its output is always up to date with
the parser.
# User-Facing Changes
- The order of output rows for `help operators` was changed.
- `not` is now listed as a boolean operator instead of a comparison
operator.
- Edited some of the descriptions for the operators.
# Description
Bug fix: `PipelineData::check_external_failed()` was not preserving the
original `type_` and `known_size` attributes of the stream passed in for
streams that come from children, so `external-command | into binary` did
not work properly and always ended up still being unknown type.
# User-Facing Changes
The following test case now works as expected:
```nushell
> head -c 2 /dev/urandom | into binary
# Expected: pretty hex dump of binary
# Previous behavior: just raw binary in the terminal
```
# Tests + Formatting
Added a test to cover this to `into binary`

# Description
With #13254, the content-type pipeline metadata field was added. This
pull request allows it to be manipulated with `metadata set`
# User-Facing Changes
* `metadata set` now has a `--content-type` flag
# Description
Provides the ability to use http commands as part of a pipeline.
Additionally, this pull requests extends the pipeline metadata to add a
content_type field. The content_type metadata field allows commands such
as `to json` to set the metadata in the pipeline allowing the http
commands to use it when making requests.
This pull request also introduces the ability to directly stream http
requests from streaming pipelines.
One other small change is that Content-Type will always be set if it is
passed in to the http commands, either indirectly or throw the content
type flag. Previously it was not preserved with requests that were not
of type json or form data.
# User-Facing Changes
* `http post`, `http put`, `http patch`, `http delete` can be used as
part of a pipeline
* `to text`, `to json`, `from json` all set the content_type metadata
field and the http commands will utilize them when making requests.
# Description
I introduced a regression in #13272 that resulted in `detect columns
--guess` to panic whenever it had to handle empty, whitespace-only, or
non-whitespace-only lines that go all the way to the last column (and as
such, cannot be considered to be lines that only have entries for the
first colum). I fix this by detecting these cases and skipping them,
since these are usually decoration lines. An example is the second line
output by `winget list`:
What we don't want to skip, however, is lines that contain no
whitespace, and fit into the detected first column, since these lines
represent cases where data is only available for the first column, and
are not just decoration lines. For example (made up example, there are
no such entries in `winget lits`'s output), in this output we would not
want to skip the `Docker Desktop` line :
```
Name Id Version Available Source
-------------------------------------------------------------------------------------------------------------------------------------
AMD Software ARPMachineX64AMD Catalyst Install Manager 24.4.1
AMD Ryzen Master ARPMachineX64AMD Ryzen Master 2.13.0.2908
Docker Desktop
Mozilla Firefox (x64 en-US) Mozilla.Firefox 127.0.2 winget
```
NOTE: `winget list | detect columns --guess` does not panic, but sadly
still does not work as expected. I believe this is not a nushell issue
anymore, but a `winget` one. When being piped, `winget` seems to add
extra whitespace and random `\r` symbols at the beginning of the text.
This messes with the column detection, of course.
# User-Facing Changes
`detect columns --guess` should not panic when receiving output from
`winget list` at all anymore.
A breaking change is the skipping of decoration lines, especially since
scripts probably were doing something like
`winget list | lines | reject 1 | str join "\n" | detect columns
--guess`. This will now cause them to reject a line with valid data.

Added tests that exercise these edge cases, as well as a single-column
test to make sure that trivial cases keep working.

This PR fixes#13269. The splitting code in `guess_width.rs` was
creating slices from char indices, instead of byte indices. This works
perfectly fine for 1-byte code points, but panics or returns wrong
results as soon as multibyte codepoints appear in the input. I
originally discovered this by piping `winget list` into `detect columns
--guess`, since winget sometimes uses the unicode ellipsis symbol (`…`)
which is 3 bytes long when encoded in utf-8.

example to the `find` command to document that non-regex mode is case
insensitive, which may surprise some users.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
