# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
```rust
record! {
"key1" => some_value,
"key2" => Value::string("text", span),
"key3" => Value::int(optional_int.unwrap_or(0), span),
"key4" => Value::bool(config.setting, span),
}
```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.
Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants
Should unblock https://github.com/nushell/nushell/pull/9678
### Example:
```nushell
module spam {
export module eggs {
export module bacon {
export const viking = 'eats'
}
}
}
use spam
print $spam.eggs.bacon.viking # prints 'eats'
use spam [eggs]
print $eggs.bacon.viking # prints 'eats'
use spam eggs bacon viking
print $viking # prints 'eats'
```
### Limitation 1:
Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ] # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ] # obviously wrong name for a constant, but doesn't work also for commands
```
Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]
print $bacon.viking # prints 'eats'
```
I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.
### Limitation 2:
`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".
But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.
# User-Facing Changes
Command category changed from `deprecated` to `removed`
Running tests locally from nushell with customizations (i.e.
$env.PROMPT_COMMAND etc) may lead to failing tests as that customization
leaks to the sandboxed nu itself.
Remove `FILE_PWD` from env
# Tests + Formatting
Tests are now passing locally without issue in my case
# Description
This PR does three related changes:
* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.
Combined, the above allow the user to see the script name in the help
output of scripts, like so:
NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.
# User-Facing Changes
One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

This PR should close#8036, #9028 (in the negative) and #9118.
Fix for #9118 is a bit pedantic. As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec

```

208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".
# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).
# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.
## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.
Scripts that depended on month or year time units on output will need to
be changed.
### Examples
```
> 365day
52wk 1day
## Used to be:
## 1yr
> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day │ 1 │
│ sign │ + │
╰──────┴────╯
## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week │ 56 │
│ day │ 6 │
│ hour │ 6 │
│ minute │ 7 │
│ second │ 8 │
│ millisecond │ 9 │
│ microsecond │ 10 │
│ nanosecond │ 11 │
│ sign │ + │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.
Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

# Description
This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.
This sets the default config value in both the Rust and the default
nushell config.
To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.
Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

# Description
This PR changes `Value::columns` to return a slice of columns instead of
cloning said columns. If the caller needs an owned copy, they can use
`slice::to_vec` or the like. This eliminates unnecessary Vec clones

fix#9796
Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.
Created a bunch of tests.

Note:
This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.
PS: Haven't tested on a wrapped/expanded tables.

Reverts nushell/nushell#9796
This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).
A patch to play with.
Need to make a few tests after all.
The question is what shall be done with `table.mode = none`, as it has
no borders.

Relative: #8248
After this pr, user can define const variable inside a module.
And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):
## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`
## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.
It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.
What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.
## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.
# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.
# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.
Simplifies the example testing a bit.
# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.
## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`
## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011

this should not change anything, just make sure the default behaviour of
Nushell and the `default_config.nu` are in sync.

# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).
Work for #8670
## description
this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
_ if $x starts-with 'nu' => {},
$x => {}
}
```
these work pretty much like rust's match guards, with few limitations:
1. multiple matches using the `|` are not (yet?) supported
```nushell
match $num {
0 | _ if (is-odd $num) => {},
_ => {}
}
```
2. blocks cannot be used as guards, (yet?)
```nushell
match $num {
$x if { $x ** $x == inf } => {},
_ => {}
}
```
## checklist
- [x] syntax

# Description
This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.
This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.

This work enforces many more checks on pipeline type correctness than

# Description
This PR removes the compile-time overload system. Unfortunately, this
system never worked correctly because in a gradual type system where
types can be `Any`, you don't have enough information to correctly
resolve function calls with overloads. These resolutions must be done at
runtime, if they're supported.
That said, there's a bit of work that needs to go into resolving
input/output types (here overloads do not execute separate commands, but
the same command and each overload explains how each output type
corresponds to input types).
This PR also removes the type scope, which would give incorrect answers
in cases where multiple subexpressions were used in a pipeline.
# User-Facing Changes
Finishes removing compile-time overloads. These were only used in a few
places in the code base, but it's possible it may impact user code. I'll
mark this as breaking change so we can review.

# User-Facing Changes
**[BREAKING CHANGE]**
this change adds a field to `SyntaxShape::Table` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the table expects, `SyntaxShape::Table(vec![])` will
suffice
# Description
the current subtyping rule needs you to define the record entries in the
same order as declared in the annotation. this pr improves that
now
```nushell
{ name: 'Him', age: 12 }
# ,
{ age: 100, name: 'It' }
# and
{ name: 'Red', age: 69, height: "5-8" }
# will all match
record<name: string, age: int>
# previously only the first one would match
```
however, something like
```nushell
{ name: 'Her' } # will not
# and
{ name: 'Car', wheels: 5 }
```
EDIT: applied JT's suggestion
# Description
We previously simply searched all commands in the working set. As our
deprecated/removed subcommands are documented by stub commands that
don't do anything apart from providing a message, they were still
included.
With this change we check the `Signature.category` to not be
`Category::Deprecated`.
## Note on performance
Making this change will exercise `Command.signature()` more
frequently! As the rust-implemented commands include their builders here
this probably will cause a number of extra allocations. There is
actually no valid reason why the commands should construct a new
`Signature` for each call to `Command.signature()`.
This will introduce some overhead to generate the completions for
commands.

# Description
For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.
So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.
Before:
```
let-env FOO = "BAR"
```
Now:
```
$env.FOO = "BAR"
```
It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

# Description
This PR does a few things to help improve type hovers and, in the
process, fixes a few outstanding issues in the type system. Here's a
list of the changes:
* `for` now will try to infer the type of the iteration variable based
on the expression it's given. This fixes things like `for x in [1, 2, 3]
{ }` where `x` now properly gets the int type.
* Removed old input/output type fields from the signature, focuses on
the vec of signatures. Updated a bunch of dataframe commands that hadn't
moved over. This helps tie things together a bit better
* Fixed inference of types from subexpressions to use the last
expression in the block
* Fixed handling of explicit types in `let` and `mut` calls, so we now
respect that as the authoritative type
I also tried to add `def` input/output type inference, but unfortunately
we only know the predecl types universally, which means we won't have
enough information to properly know what the types of the custom
commands are.
# User-Facing Changes
Script typechecking will get tighter in some cases
Hovers should be more accurate in some cases that previously resorted to
any.

# Description
`chrono::Datetime::to_rfc2822()` panics when it would format a negative
year. 3339 does not. This makes negative-year datetimes inconsistent
compared to positive ones, but it's better than a panic.
# Description
`derive(EnumIter)` is only required to run completeness tests.
Thus make the derive conditional on test and move `strum` and
`strum_macros` to the dev dependencies.
## Is it worth it?
Removing this derive does not change the binary size (checked via `cargo
bloat --crates` from `cargo-bloat`).
Compile time change is below a second so hard to judge based on a single
run of `cargo clean --profile dev; cargo build --timings`
Unsure if this negatively impacts how incremental compilation can
recompile when you switch between `cargo build`/`run` and `cargo test`
in your local workflow.
To get rid of `strum`/`strum_macros` as a proc macro crate we would need
to also remove it from `reedline`.
Further more a crate in the `polars` dependency tree uses `strum`
(curently not as relevant for the 1.0 build).

# Description
This PR cleans up the deprecated legacy config options that were
deprecated in nushell version 0.72.0. These are the config points that
were in the root of the config but also duplicated in the nested
structures. For instance `use_ls_colors` was in the root of the config
and also in the `ls.use_ls_colors` nested structure. This was originally
done to preserve backwards compatibility when nested structures were
introduced in the config file.
Here's a list of the legacy config points that were removed.
- `use_ls_colors` - previously replaced with `ls.use_ls_colors`
- `rm_always_trash` - previously replaced with `rm.always_trash`
- `history_file_format` - previously replaced with `history.file_format`
- `sync_history_on_enter` - previously replaced with
`history.sync_on_enter`
- `max_history_size` - previously replaced with `history.max_size`
- `quick_completions` - previously replaced with `completions.quick`
- `partial_completions` - previously replaced with `completions.partial`
- `max_external_completion_results` - previously replaced with
`completions.external.max_results`
- `completion_algorithm` - previously replaced with
`completions.algorithm`
- `case_sensitive_completions` - previously replaced with
`completions.case_sensitive`
- `enable_external_completion` - previously replaced with
`completions.external.enable`
- `external_completer` - previously replaced with
`completions.external.completer`
- `table_mode` - previously replaced with `table.mode`
- `table_index_mode` - previously replaced with `table.index_mode`
- `table_trim` - previously replaced with `table.trim`
- `show_clickable_links_in_ls` - previously replaced with
`ls.clickable_links`
- `cd_with_abbreviations` - previously replaced with `cd.abbreviations`
- `filesize_metric` - previously replaced with `filesize.metric`
- `filesize_format` - previously replaced with `filesize.format`
- `cursor_shape_vi_insert` - previously replaced with
`cursor_shape.vi_insert`
- `cursor_shape_vi_normal` - previously replaced with
`cursor_shape.vi_normal`
- `cursor_shape_emacs` - previously replaced with `cursor_shape.emacs`
Removes log_level from the config since it doesn't do anything any
longer. We moved log-level to a nushell parameter some time ago.
Renames history_isolation to isolation in the config.nu for consistency.
Fixes a couple bugs where values weren't being set in the "//
Reconstruct" sections (history_isolation, table_show_empty).
Reorganized/Moved things around a tiny bit and added a few comments.
# User-Facing Changes
history.histor_isolation is now history.isolation.
If anyone is still using the legacy config points, deprecated since
0.72.0 2022-11-29, their config will break.

In my view we should revert nushell/nushell#8395 for now
## Potentially inconsistent application of semantic change
#8395 (1d5e7b441b) was loosening the type
coercion rules significantly, to let missing data / void returns that
were either expressed by `PipelineData::Empty` or the `Value::nothing`
be accept by specifically those commands/operations that made use of
`PipelineData::into_iter_strict()`. This could apply the new rules
inconsistently.
## Turning explicit failures into silent continuations
Furthermore the effect of this breaking change to the missing data
semantics could make previous errors into silent failures.
This could either just reduce the effectiveness of teaching error
messages in interactive use:
### Contrived example before
```bash
> cd . | where blah
Error: nu:🐚:only_supports_this_input_type
× Input type not supported.
╭─[entry #13:1:1]
1 │ cd . | where blah
· ──┬──┬
· │ ╰── input type: null
· ╰── only list, binary, raw data or range input data is supported
╰────
```
### ...after, with #8395
```bash
> cd . | where blah
╭────────────╮
│ empty list │
╰────────────╯
```
In rare cases people could already try to rely on catching an error of a
downstream command to actually deal with the missing data, so it would
be a breaking change for their existing code.
## Problem with `PipelineData::into_iter_strict()`
Maybe this makes `_strict` a bit of a misnomer for this particular
iterator construction.
Further we did not actively test the `PipelineData::empty` branch before
## Parsimonious solution exists
For the motivating issue https://github.com/nushell/nushell/issues/8393
there already exists a fix that makes `ls` more consistent with the type
system by returning an empty `Value::List`
https://github.com/nushell/nushell/pull/8439
# Description
This allows empty pipelines to pass their emptiness through a filter.
This helps fix issues like trying to run a filter on an `ls` in an empty
directory. It also feels a bit more reasonable that a filter filters
what is *there* but doesn't require something to be there.
fixes#8393
# User-Facing Changes
No breaking changes (that I know of). Should allow filtering to be a
little less surprising with emptiness.

This PR reverts https://github.com/nushell/nushell/pull/9391
We try not to revert PRs like this, though after discussion with the
Nushell team, we decided to revert this one.
The main reason is that Nushell, as a codebase, isn't ready for these
kinds of optimisations. It's in the part of the development cycle where
our main focus should be on improving the algorithms inside of Nushell
itself. Once we have matured our algorithms, then we can look for
opportunities to switch out technologies we're using for alternate
forms.
Much of Nushell still has lots of opportunities for tuning the codebase,
paying down technical debt, and making the codebase generally cleaner
and more robust. This should be the focus. Performance improvements
should flow out of that work.
Said another, optimisation that isn't part of tuning the codebase is
premature at this stage. We need to focus on doing the hard work of
making the engine, parser, etc better.

# Description
Despite the innocent-looking title, this PR involves quite a few backend
changes as the existing LazyRecord trait was not at all friendly towards
the idea of these values being generated on the fly from Nu code.
In particular, here are a few changes involved:
- The LazyRecord trait now involves a lifetime `'a`, and this lifetime
is used in the return value of `get_column_names`. This means it no
longer returns `'static str`s (but implementations still can return
these). This is more stringent on the consumption side.
- The LazyRecord trait now must be able to clone itself via a new
`clone_value` method (as requiring `Clone` is not object safe). This
pattern is borrowed from `Value::CustomValue`.
- LazyRecord no longer requires being serde serializable and
deserializable.
These, in hand, allow for the following:
- LazyRecord can now clone itself, which means that they don't have to
be collected into a Record when being cloned.
- This is especially useful in Stack, which is cloned on each repl line
and in a few other cases. This would mean that _every_ LazyRecord
instance stored in a variable would be collected in its entirety and
cloned, which can be catastrophic for performance. See: `let nulol =
$nu`.
- LazyRecord's columns don't have to be static, they can have the same
lifetime of the struct itself, so different instances of the same
LazyRecord type can have different columns and values (like the new
`NuLazyRecord`)
- Serialization and deserialization are no longer meaningless, they are
simply less.
I would consider this PR very "drafty", but everything works. It
probably requires some cleanup and testing, though, but I'd like some
eyes and pointers first.
# User-Facing Changes
New command. New restrictions are largely internal. Maybe there are some
plugins affected?
Example of new command's usage:
```
lazy make --columns [a b c] --get-value { |name| print $"getting ($name)"; $name | str upcase }
```
You can also trivially implement something like `lazy make record` to
take a record of closures and turn it into a getter-like lazy struct:
```
def "lazy make record" [
record: record
] {
let columns = ($record | columns)
lazy make --columns $columns --get-value { |col| do ($record | get $col) }
}
```
Open to bikeshedding. `lazy make` is similar to `error make` which is
also in the core commands. I didn't like `make lazy` since it sounded
like some transformation was going on.
# Tour for reviewers
Take a look at LazyMake's examples. They have `None` as the results, as
such they aren't _really_ correct and aren't being tested at all. I
didn't do this because creating the Value::LazyRecord is a little tricky
and didn't want to risk messing it up, especially as the necessary
variables aren't available when creating the examples (like stack and
engine state).
Also take a look at NuLazyRecord's get_value implementation, or in
general. It uses an Arc<Mutex<_>> for the stack, which must be accessed
mutably for eval_block but get_value only provides us with a `&self`.
This is a sad state of affairs, but I don't know if there's a better
way.
On the same code path, we also have pipeline handling, and any pipeline
that isn't a Pipeline::Value will return Value::nothing. I believe
returning a Value::Error is probably better, or maybe some other
handling. Couldn't decide on which ShellError to settle with for that
branch.
The "unfortunate casualty" in the columns.rs file. I'm not sure just how
bad that is, though, I simply had to fight a little with the borrow
checker.
A few leftover comments like derives, comments about the now
non-existing serde requirements, and impls. I'll definitely get around
to those eventually but they're in atm
Should NuLazyRecord implement caching? I'm leaning heavily towards
**yes**, this was one of the main reasons not to use a record of
closures (besides convenience), but maybe it could be opt-out. I'd
wonder about its implementation too, but a simple way would be to move a
HashMap into the mutex state and keep cached values there.
# Description
Fixes: #8565
Here is another pr #7240 tried to address the issue, but it works in a
wrong way.
After this change `o+e>` won't redirect all stdout message then stderr
message and it works more like how bash does.
# User-Facing Changes
For the given python code:
```python
# test.py
import sys
print('aa'*300, flush=True)
print('bb'*999999, file=sys.stderr, flush=True)
print('cc'*300, flush=True)
```
Running `python test.py out+err> a.txt` shoudn't hang nushell, and
`a.txt` keeps output in the same order
## About the change
The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SameTargetRedirection` if we meet `out+err>` redirection
token(which is generated by lex function),
During converting from lite block to block,
LiteElement::SameTargetRedirection will be converted to
PipelineElement::SameTargetRedirection.
Then in the block eval process, if we get
PipelineElement::SameTargetRedirection, we'll invoke `run-external` with
`--redirect-combine` flag, then pipe the result into save command
## What happened internally?
Take the following command as example:
`^ls o+e> log.txt`
lex parsing result(`Tokens`) are not changed, but `LiteBlock` and
`Block` is changed after this pr.
### LiteBlock before
```rust
LiteBlock {
block: [
LitePipeline { commands: [
Command(None, LiteCommand { comments: [], parts: [Span { start: 39041, end: 39044 }] }),
// actually the span of first Redirection is wrong too..
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
]
}]
}
```
### LiteBlock after
```rust
LiteBlock {
block: [
LitePipeline {
commands: [
SameTargetRedirection {
cmd: (None, LiteCommand { comments: [], parts: [Span { start: 147945, end: 147948}]}),
redirection: (Span { start: 147949, end: 147957 }, LiteCommand { comments: [], parts: [Span { start: 147958, end: 147965 }]})
}
]
}
]
}
```
### Block before
```rust
Pipeline {
elements: [
Expression(None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),
span: Span { start: 39041, end: 39044 },
ty: Any, custom_completion: None
}),
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None })] }
```
### Block after
```rust
Pipeline {
elements: [
SameTargetRedirection {
cmd: (None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 147946, end: 147948 }, ty: String, custom_completion: None}, [], false),
span: Span { start: 147945, end: 147948},
ty: Any, custom_completion: None
}),
redirection: (Span { start: 147949, end: 147957}, Expression {expr: String("log.txt"), span: Span { start: 147958, end: 147965 },ty: String,custom_completion: None}

# Description
<!--
Thank you for improving Nushell. 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

Show parameter defaults in scope command signature, where they're
available for display by help.
per https://github.com/nushell/nushell/issues/8928.
I found unexpected ramifications in one completer (NuHelpCompleter) and
plugins, which both use the flag-formatting routine from builtin help.
For the moment I made the minimum necessary changes to get the mainline
scenario to pass tests and run. But we should circle back on what to do
with plugins and help completer..
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
1. New `parameter_default` column to `signatures` table in
`$nu.scope.commands`
It is populated with whatever parameters can be defaulted: currently
positional args and named flags.
2. Built in help (both `help <command>` and `<command> --help` will
display the defaults
3. Help completer will display defaults for flags, but not for
positionals.
Example:
A custom command with some default parameters:
```
〉cat ~/work/dflts.nu
# sample function to show defaults in help
export def main [
arg1: string # mandatory positional
arg2:string=abc # optional positional
--switch # no default here
--named:int # named flag, no default
--other:string=def # flag
--hard:record<foo:int bar:string, bas:bool> # default can be compound type
= {foo:22, bar:"other worlds", bas:false}
] { {arg1: $arg1,
arg2: $arg2,
switch: $switch,
named: $named,
other: $other,
hard: $hard, }
}
〉use ~/work/dflts.nu
〉$nu.scope.commands | where name == 'dflts' | get signatures.0.any | reject short_flag description custom_completion

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

# Description
Follow-up of #8940. As @bobhy pointed out, it makes sense for the
behaviour of flags to match the one for positional arguments, where
default values are of type `Option<Value>` instead of
`Option<Expression>`.
# User-Facing Changes
The same ones from the original PR:
- Flag default values will now be parsed as constants.
- If the default value is not a constant, a parser error is displayed.
# Tests + Formatting
A [new
test](e34e2d35f4/src/tests/test_engine.rs (L338-L344))
has been added to verify the new restriction.
# Description
This PR impacts the nushell sqlite history only.
This is the first PR that enables history isolation in nushell for the
sqlite history. Hopefully, we can continue building on this.
This PR allows "history isolation" which means that other nushell
session's history won't be available in the current session when using
the uparrow/downarrow history navigation. This change only impacts the
uparrow downarrow history navigation.
What remains to be done is making ctrl+r history menu respect this
setting too. Right now, the history menu will still show you all entries
from all sessions.
The history command also shows all history items from all sessions. This
may remain unchanged since you can just filter by history session right
now.
This also fixes a bug where the session id is 0 in the sqlite history
since my April 18th reedline PR.
Closes#9064

# Description
Fixes#8939.
# User-Facing Changes
- Parameter default values will now be parsed as constants.
- If the default value is not a constant, a parser error is displayed.
# Tests + Formatting
The [only affected
test](d42c2b2dbc/src/tests/test_engine.rs (L325-L328))
has been updated to reflect the new behavior.
# Description
follow up to #8529
cleaned up version of #8892
- the original syntax is okay
```nu
def okay [rec: record] {}
```
- you can now add type annotations for fields if you know
them before hand
```nu
def okay [rec: record<name: string>] {}
```
- you can specify multiple fields
```nu
def okay [person: record<name: string age: int>] {}
# an optional comma is allowed
def okay [person: record<name: string, age: int>] {}
```
- if annotations are specified, any use of the command will be type
checked against the specified type
```nu
def unwrap [result: record<ok: bool, value: any>] {}
unwrap {ok: 2, value: "value"}
# errors with
Error: nu::parser::type_mismatch
× Type mismatch.
╭─[entry #4:1:1]
1 │ unwrap {ok: 2, value: "value"}
· ───────┬─────
· ╰── expected record<ok: bool, value: any>, found record<ok: int, value: string>
╰────
```
> here the error is in the `ok` field, since `any` is coerced into any
type
> as a result `unwrap {ok: true, value: "value"}` is okay
- the key must be a string, either quoted or unquoted
```nu
def err [rec: record<{}: list>] {}
# errors with
Error:
× `record` type annotations key not string
╭─[entry #7:1:1]
1 │ def unwrap [result: record<{}: bool, value: any>] {}
· ─┬
· ╰── must be a string
╰────
```
- a key doesn't have to have a type in which case it is assumed to be
`any`
```nu
def okay [person: record<name age>] {}
def okay [person: record<name: string age>] {}
```
- however, if you put a colon, you have to specify a type
```nu
def err [person: record<name: >] {}
# errors with
Error: nu::parser::parse_mismatch
× Parse mismatch during operation.
╭─[entry #12:1:1]
1 │ def unwrap [res: record<name: >] { $res }
· ┬
· ╰── expected type after colon
╰────
```
# User-Facing Changes
**[BREAKING CHANGES]**
- this change adds a field to `SyntaxShape::Record` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the record expects, `SyntaxShape::Record(vec![])`
will suffice
# Description
This PR changes the `ast` command to be able to output `--json` as well
as `nuon` (default) with "pretty" and "minified" output. I'm hoping this
functionality will be usable in the vscode extension for semantic
tokenization and highlighting.
# User-Facing Changes
There's a new `--json`/`-j` option. Prior version output of nuon is
maintained as default.

# Description
Close: #8988
Thanks to new crossterm version, nushell can support blink cursor shape.
It can be config with the following value:
1. blink_block
2. blink_line
3. blink_underscore
And original block, line, underscore will be steady. It also fixes wrong
shape of `underscore`.
# User-Facing Changes
Here is a little breaking change, before the change: `line` cursor shape
is blinking line, but after this pr, it will be `steady line`. To make a
blink line, we need to change the value to `blink_line`.
But I think it's ok, because after the change, we have a good naming
convention about the name of shape

# Description
This does a lookup in the cache of parsed files to see if a span can be
found for a file that was previously loaded with the same contents, then
uses that span to find the parsed block for that file. The end result
should, in theory, be identical but doesn't require any reparsing or
creating new blocks/new definitions that aren't needed.
This drops the sg.nu benchmark from:

# Description
_Fixes #5923_
Currently `nushell` doesn't allow short flag batches to contain
arguments, despite this being a common pattern in commands like `git
commit -am 'My commit message'`. This PR relaxes this so that the last
flag in the batch can take an argument.
# User-Facing Changes
- `nu::parser::short_flag_arg_cant_take_arg` has been replaced by
`nu::parser::only_last_flag_in_batch_can_take_arg` and is displayed when
a flag other then the last in a short flag batch takes an argument.
# Tests + Formatting
- Both
[`test_parser.rs`](48af0ebc3c/crates/nu-parser/tests/test_parser.rs (L640-L704))
and
[`test_known_external.rs`](48af0ebc3c/src/tests/test_known_external.rs (L42-L61))
have been updated to test the new allowed and disallowed scenarios.

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

now nu_std only depends on nu_parser, nu_protocol and miette
and removes the nu_cli dependency
this enables developers moving forward to come along and implement their
own CLI's without having to pull in a redundant nu-cli which will not be
needed for them.
I did this by moving report_error into nu_protocol
which nu_std already has a dependency on anyway....

This improves the operation mismatch error in a few ways:
* We now detect if the left-hand side of the operation is at fault, and

# Description
This is a pretty heavy refactor of the parser to support multiple parser
errors. It has a few issues we should address before landing:
- [x] In some cases, error quality has gotten worse `1 / "bob"` for
example
- [x] if/else isn't currently parsing correctly
- probably others

I would like to get this in for 0.78, I think it's low-risk and I want
the `?` feature to be as polished as possible for its debut.
# Description
Adds two more patterns when working with lists:
```
[1, ..$remainder]
```
and
```
[1, ..]
```
The first one collects the remaining items and assigns them into the
variable. The second one ignores any remaining values.
# User-Facing Changes
Adds more capability to list pattern matching.

# Description
Adds `|` patterns to `match`, allowing you to try multiple patterns for
the same case.
Example:
```
match {b: 1} { {a: $b} | {b: $b} => { print $b } }
```
Variables that don't bind are set to `$nothing` so that they can be
later checked.

# Description
This removes autoprinting the final value of a loop, much in the same
spirit as not autoprinting values at the end of statements. As we fix
these corner cases, it becomes more consistent that to print to the
screen in a script, you use the `print` command.
This gives a noticeable performance improvement as a bonus.
Before:
```
C:\Source\nushell〉 for x in 1..10 { $x }
1
2
3
4
5
6
7
8
9
10
```
Now:
```
C:\Source\nushell〉 for x in 1..10 { $x }
C:\Source\nushell〉
```
# User-Facing Changes
**BREAKING CHANGE**
Loops like `for`, `loop`, and `while` will no longer automatically print
loop values to the screen.

Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`)
would throw an error if either side was null. After this PR, these
operators return null if either side (or both) is null.
### Examples
```bash
1 < 3 # true
1 < null # null
null < 3 # null
null < null # null
```
### Motivation
JT [asked the C#
folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140)
and this is apparently the approach they would choose for comparison
operators if they could start from scratch.
This PR makes `where` more convenient to use on jagged/missing data. For
example, we can now filter on columns that may not be present in every
row:
```
> [{foo: 123} {}] | where foo? > 10
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │ 123 │
╰───┴─────╯
```
# Description
This does a few speedups for tight loops:
* Caches the DeclId for `table` so we don't look it up. This means users
can't easily replace the default one, we might want to talk about this
tradeoff. The lookup for finding `table` in a tight loop is currently
pretty heavy. Might be another way to speed this up.
* `table` no longer pre-calculates the width. Instead, it only
calculates the width when printing a table or record.
* Use more efficient way of collecting the block of each loop
* When printing output, only get the config when needed
Combined, this drops the runtime from a million loop tight iteration
from 1sec 8ms to 236ms.

Some minor code cleanup.
We've accumulated a few macros over the years that arguably don't need
to be macros. This PR removes 4 macros by either:
1. Inlining the macro
2. Replacing the macro with a local function
3. Replacing the macro with a closure
# Description
Add float, string, and date patterns to matcher.
This could probably use some tests 😅

# Description
This moves the representation of variables on the stack to a Vec, which
more closely resembles a stack. For small numbers of variables live at
any one point, this tends to be more efficient than a HashMap. Having a
stack-like vector also allows us to remember a stack position,
temporarily push variables on, then quickly drop the stack back to the
original size when we're done. We'll need this capability to allow
matching inside of conditions.
On this mac, a simple run of:
`timeit { mut x = 1; while $x < 1000000 { $x += 1 } }`
Went from 1 sec 86 ms, down to 1 sec 2 ms. Clearly, we have a lot more
ground we can make up in looping speed 😅 but it's nice that for fixing
this to make matching easier, we also get a win in terms of lookup speed
for small numbers of variables.

# Description
This adds `match` and basic pattern matching.
An example:
```
match $x {
1..10 => { print "Value is between 1 and 10" }
{ foo: $bar } => { print $"Value has a 'foo' field with value ($bar)" }
[$a, $b] => { print $"Value is a list with two items: ($a) and ($b)" }
_ => { print "Value is none of the above" }
}
```
Like the recent changes to `if` to allow it to be used as an expression,
`match` can also be used as an expression. This allows you to assign the
result to a variable, eg) `let xyz = match ...`
I've also included a short-hand pattern for matching records, as I think
it might help when doing a lot of record patterns: `{$foo}` which is
equivalent to `{foo: $foo}`.
There are still missing components, so consider this the first step in
full pattern matching support. Currently missing:
* Patterns for strings
* Or-patterns (like the `|` in Rust)
* Patterns for tables (unclear how we want to match a table, so it'll
need some design)
* Patterns for binary values
* And much more

This is a follow-up to https://github.com/nushell/nushell/pull/8379 and
https://github.com/nushell/nushell/discussions/8502.
This PR makes it so that the new `?` syntax for marking a path member as
optional short-circuits, as voted on in the
[8502](https://github.com/nushell/nushell/discussions/8502) poll.
Previously, `{ foo: 123 }.bar?.baz` would raise an error:
```
> { foo: 123 }.bar?.baz
× Data cannot be accessed with a cell path
╭─[entry #15:1:1]
1 │ { foo: 123 }.bar?.baz
· ─┬─
· ╰── nothing doesn't support cell paths
╰────
```
Here's what was happening:
1. The `bar?` path member access returns `nothing` because there is no field named `bar` on the record
2. The `baz` path member access fails when trying to access a `baz` field on that `nothing` value
After this change, `{ foo: 123 }.bar?.baz` returns `nothing`; the failed `bar?` access immediately returns `nothing` and the `baz` access never runs.
# Description
Add a `command_not_found` function to `$env.config.hooks`. If this
function outputs a string, then it's included in the `help`.
An example hook on *Arch Linux*, to find packages that contain the
binary, looks like:
```nushell
let-env config = {
# ...
hooks: {
command_not_found: {
|cmd_name| (
try {
let pkgs = (pkgfile --binaries --verbose $cmd_name)
(
$"(ansi $env.config.color_config.shape_external)($cmd_name)(ansi reset) " +
$"may be found in the following packages:\n($pkgs)"
)
} catch {
null
}
)
}
# ...
```

- Add a `command_not_found` function to `$env.config.hooks`.

when running the tests inside nu-protocol we were getting a compiler
warning...
this PR removes the compiler warning from nu-protocol.
by adding
```rust
#[allow(unused_imports)]
```
Reverts nushell/nushell#8310
In anticipation that we may want to revert this PR. I'm starting the
process because of this issue.
This stopped working
```
let-env NU_LIB_DIRS = [
($nu.config-path | path dirname | path join 'scripts')
'C:\Users\username\source\repos\forks\nu_scripts'
($nu.config-path | path dirname)
]
```
You have to do this now instead.
```
const NU_LIB_DIRS = [
'C:\Users\username\AppData\Roaming\nushell\scripts'
'C:\Users\username\source\repos\forks\nu_scripts'
'C:\Users\username\AppData\Roaming\nushell'
]
```
In talking with @kubouch, he was saying that the `let-env` version
should keep working. Hopefully it's a small change.
# Description
Allow NU_LIBS_DIR and friends to be const they can be updated within the
same parse pass. This will allow us to remove having multiple config
files eventually.
Small implementation detail: I've changed `call.parser_info` to a
hashmap with string keys, so the information can have names rather than
indices, and we don't have to worry too much about the order in which we
put things into it.
Closes https://github.com/nushell/nushell/issues/8422
# User-Facing Changes
In a single file, users can now do stuff like
```
const NU_LIBS_DIR = ['/some/path/here']
source script.nu
```
and the source statement will use the value of NU_LIBS_DIR declared the
line before.
Currently, if there is no `NU_LIBS_DIR` const, then we fallback to using
the value of the `NU_LIBS_DIR` env-var, so there are no breaking changes
(unless someone named a const NU_LIBS_DIR for some reason).

# Description
Resolves issue #8370
Adds the following flags to commands `from csv` and `from tsv`:
- `--flexible`: allow the number of fields in records to be variable
- `-c --comment`: a comment character to ignore lines starting with it
- `-q --quote`: a quote character to ignore separators in strings,
defaults to '\"'
- `-e --escape`: an escape character for strings containing the quote
character
Internally, the `Value` struct has an additional helper function
`as_char` which converts it to a single `char`
# User-Facing Changes
The single quoted string `'\t'` can no longer be used as a parameter for
the flag `--separator '\t'` as it is interpreted as a two-character
string. One needs to use from now on the flag with a double quoted
string like so: `-s "\t"` which correctly interprets the string as a
single `char`.
# Description
This fixes the `commandline` command when it's run with no arguments, so
it outputs the command being run. New line characters are included.
This allows for:
- [A way to get current command inside pre_execution hook · Issue #6264
· nushell/nushell](https://github.com/nushell/nushell/issues/6264)
- The possibility of *Atuin* to work work *Nushell*. *Atuin* hooks need
to know the current repl input before it is run.

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

# Breaking changes
1. Column names with `?` in them now need to be quoted.
2. The `-i`/`--ignore-errors` flag has been removed from `get` and
`select`
1. After this PR, most `get` error handling can be done with `?` and/or
`try`/`catch`.
4. Cell path accesses like this no longer work without a `?`:
```bash
〉[{a:1 b:2} {a:3}].b.0
2
```
We had some clever code that was able to recognize that since we only
want row `0`, it's OK if other rows are missing column `b`. I removed
that because it's tricky to maintain, and now that query needs to be
written like:
```bash
〉[{a:1 b:2} {a:3}].b?.0
2
```
I think the regression is acceptable for now. I plan to do more work in
the future to enable streaming of cell path accesses, and when that
happens I'll be able to make `.b.0` work again.
# Description
The correction made here concerns the issue #8431. Indeed, the algorithm
initially proposed to remove elements of a `vector` performed a loop
with `remove` and an incident therefore appeared when several values
were equal because the deletion was done outside the length of the
vector:
```rust
let mut found = false;
for (i, col) in cols.clone().iter().enumerate() {
if col == col_name {
cols.remove(i);
vals.remove(i);
found = true;
}
}
```
Then, `[[a, a]; [1, 2]] | reject a: ` gave `thread 'main' panicked at
'removal index (is 1) should be < len (is 1)',
crates/nu-protocol/src/value/mod.rs:1213:54`.
The proposed correction is therefore the implementation of the
`retain_mut` utility dedicated to this functionality.
```rust
let mut found = false;
let mut index = 0;
cols.retain_mut(|col| {
if col == col_name {
found = true;
vals.remove(index);
false
} else {
index += 1;
true
}
});
```
# Description
Our `ShellError` at the moment has a `std::mem::size_of<ShellError>` of
136 bytes (on AMD64). As a result `Value` directly storing the struct
also required 136 bytes (thanks to alignment requirements).
This change stores the `Value::Error` `ShellError` on the heap.
Pro:
- Value now needs just 80 bytes
- Should be 1 cacheline less (still at least 2 cachelines)
Con:
- More small heap allocations when dealing with `Value::Error`
- More heap fragmentation
- Potential for additional required memcopies
# Further code changes
Includes a small refactor of `try` due to a type mismatch in its large
match.
# User-Facing Changes
None for regular users.
Plugin authors may have to update their matches on `Value` if they use
`nu-protocol`
Needs benchmarking to see if there is a benefit in real world workloads.
**Update** small improvements in runtime for workloads with high volume
of values. Significant reduction in maximum resident set size, when many
values are held in memory.
# Tests + Formatting
# Description
This works around a bug introduced by #8058
We should revisit the original fix, as it makes some assumptions about
how stdout redirection is used by `table`. We use the stdout by default
for table regularly during a repl session, so we should instead
special-case case for handling externals.
# User-Facing Changes
Restores the original default `table` behaviour for binary data
# 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 -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
# After Submitting
If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
