# Description
I noticed recently these timing discrepancies. I was thinking they would
be nearly identical but they were not.
```
> nu --no-std-lib -n -c "$nu.startup-time"
13ms 686µs 209ns
> nu --no-std-lib -n
> $nu.startup-time
2ms 520µs 416ns
```
My research showed that if `-n` was passed with `-c`, then the `-n` was
essentially being ignored. This PR corrects that.
Also worthy of understanding, if `nu -c "some command"` is passed, the
default env file is always loaded. I believe that's on purpose so that a
NU_LIB_DIRS env is available.
## After this PR (on a different system)
```
> nu --no-std-lib -n -c "$nu.startup-time"
6ms 688µs 600ns
> nu -n --no-std-lib
> $nu.startup-time
6ms 661µs 800ns
```

closes#9111
# Description
this pr improves parsing of values with units (`filesizes`, `durations`
and any other **future values**) by:
1. allowing underscores in the value part
```nu
> 42kb # okay
> 42_sec # okay
> 1_000_000mib # okay
> 69k_b # not okay, underscores not allowed in the unit
```
2. improving error messages involving these values
```nu
> sleep 40-sec
# before
Error: nu::parser::parse_mismatch
× Parse mismatch during operation.
╭─[entry #42:1:1]
1 │ sleep 40-sec

# now
Error:
× duration value must be a number
╭─[entry #41:1:1]
1 │ sleep 40-sec
· ─┬─
· ╰── not a number
╰────
```
3. unifying parsing of these values. now all of these use one function
# User-Facing Changes
filesizes and durations can now have underscores for readability
Related to #8368.
# Description
as planned in #8311, the `enter`, `shells`, `g`, `n` and `p` commands
have been re-implemented in pure-`nushell` in the standard library.
this PR removes the `rust` implementations of these commands.
- all the "shells" tests have been removed from
`crates/nu-commnand/tests/commands/` in
2cc6a82da6, except for the `exit` command
- `cd` does not use the `shells` feature in its source code anymore =>
that does not change its single-shell behaviour
- all the command implementations have been removed from
`crates/nu-command/src/shells/`, except for `exit.rs` => `mod.rs` has
been modified accordingly
- the `exit` command now does not compute any "shell" related things
- the `--now` option has been removed from `exit`, as it does not serve
any purpose without sub-shells
# User-Facing Changes
users may now not use `enter`, `shells`, `g`, `n` and `p`
now they would have to use the standard library to have access to
equivalent features, thanks to the `dirs.nu` module introduced by @bobhy
in #8368

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

Related to:
- #8311
- #8353
# Description
with the new `$nu.startup-time` from #8353 and as mentionned in #8311,
we are now able to fully move the `nushell` banner from the `rust`
source base to the standard library.
this PR
- removes all the `rust` source code for the banner
- rewrites a perfect clone of the banner to `std.nu`, called `std
banner`
- call `std banner` from `default_config.nu`
# User-Facing Changes
see the demo: https://asciinema.org/a/566521
- no config will show the banner (e.g. `cargo run --release --
--no-config-file`)
- a custom config without the `if $env.config.show_banner` block and no
call to `std banner` would never show the banner
- a custom config with the block and `config.show_banner = true` will
show the banner
- a custom config with the block and `config.show_banner = false` will
NOT show the banner
# Tests + Formatting
a new test line has been added to `tests.nu` to check the length of the
`std banner` output.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# 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))

# Description
This PR fixes an issue described in #8890 where config variables
declared in command parameters cause the warning `use `let-env config =
...` instead of `let config = ...` to be printed.
# User-Facing Changes
The user is only warned when they define a config variable with a
warning with the type `record`.
# Tests + Formatting
I think this can only be tested manually by first trying to reproduce
#8890.
To test if the warning is still printed when it's supposed to be one can
add `let config = $env.config` to the end of the `config.nu` file.
# 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 }
· ┬

```
# 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 changes how the include paths are joined together so that it uses a
character that will work across platforms. `;` didn't work on Mac/Linux.
`:` didn't work in Windows. So, the record separator should work, which
is \x1e.
This goes hand-in-hand with
https://github.com/nushell/vscode-nushell-lang/pull/113.

# 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
This adds multi-file support to the in-progress IDE support. The main
new features are a `-I` flag that allows you to add a new source search
path when starting up the nu binary, and fixes for the current IDE
support to support spans in other files.
This needs accompanying fixes to the vscode/lsp implementation to pass
along the project directory via `-I`.
UPDATE: Marking this draft until we have a means to test this.

# Description
Part of the larger cratification effort.
Moves all `reedline` or shell line editor specific commands to `nu-cli`.
## From `nu-cmd-lang`:
- `commandline`
- This shouldn't have moved there. Doesn't directly depend on reedline
but assumes parts in the engine state that are specific to the use of
reedline or a REPL
## From `nu-command`:
- `keybindings` and subcommands
- `keybindings default`
- `keybindings list`
- `keybindings listen`
- very `reedline` specific
- `history`
- needs `reedline`
- `history session`
## internal use
Instead of having a separate `create_default_context()` that calls
`nu-command`'s `create_default_context()`, I added a `add_cli_context()`
that updates an `EngineState`
# User-Facing Changes
None
## Build time comparison
`cargo build --timings` from a `cargo clean --profile dev`
### total
main: 64 secs
this: 59 secs
### `nu-command` build time
branch | total| codegen | fraction
---|---|---|---
main | 14.0s | 6.2s | (44%)
this | 12.5s | 5.5s | (44%)
`nu-cli` depends on `nu-command` at the moment.
Thus it is built during the code-gen phase of `nu-command` (on 16
virtual cores)
# Tests + Formatting
I removed the `test_example()` facilities for now as we had not run any
of the commands in an `Example` test and importing the right context for
those tests seemed more of a hassle than the duplicated
`test_examples()` implementations in `nu-cmd-lang` and `nu-command`
this adds a `--no-std-lib` flag. Moves `nu!` to use the `--no-std-lib`.
Adds a new `nu_with_std!` macro for future tests that need the std-lib.

should close#8208, previous work #8435
# Description
This PR is just a minor development improvement. While working on
another feature, I noticed that the root crate lists the super useful
`pretty_assertions` in the root crate but doesn't use it in most tests.
With this change `pretty_assertions::assert_eq!` is used instead of
`core::assert_eq!` for better diffs when debugging the tests.
I thought of adding the dependency to other crates but I decided not to
since I didn't want a huge disruptive PR :)
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....

# Description
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
show a simpler error/error message if it is
* Removed the unhelpful hint
* Updated the error text to make it clear what types are causing the
issue

# Description
as we now have a prelude thanks to #8627, i'd like to work on the
structure of the library 😋
and i think the first step is to make it a true standalone crate 😏
this PR
- moves all the library from `crates/nu-utils/standard_library/` to
`crates/nu-std/`
- moves the `rust` loading code from `src/run.rs` to
`crates/nu-std/src/lib.rs`
# Description
This fixes the parser recovery after the first error (at least the main
culprit), where `parse_value` was not able to properly parse `any`
values after the first error.

# 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
# User-Facing Changes
This may have error quality degradation as we adjust to the new error
reporting mechanism.

# Description
This adds a set of new flags on the `nu` binary intended for use in
IDEs. Here is the set of supported functionality so far:
* goto-def - go to the definition of a variable or custom command
* type hints - see the inferred type of variables
* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position
# User-Facing Changes
No changes to the REPL experience. This only impacts the IDE scenario.

# Description
This PR fixes a testing bug that @rgwood found and PR #8653 introduced,
mentioned
[here](https://github.com/nushell/nushell/pull/8653#issuecomment-1491263657).
Since 8653 returns canonicalizes config paths now, the tests need to
return canonicalized paths as well. Without this PR, if you have your
nushell config dir symlinked, this test will fail. This PR fixes that
test.

# Description
This allows for type inference to infer record types in more cases. The
only time we will now fall back to `Any` is when one of the fields has a
computed value.
I also updated the type mismatch error and highlighting to be in-line
with other errors.
# User-Facing Changes
This may result in stricter type checking. Previously `{}` had the
inferred type `Any` but will now have the correct inferred type of
`Record<>`.

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 │
╰───┴─────╯

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
This is an experiment to see what switching the `let/let-env` family to
math expressions for initialisers would be like.
# User-Facing Changes
This would require any commands you call from `let x = <command here>`
(and similar family) to call the command in parentheses. `let x = (foo)`
to call `foo`.

`with-env`, `do`, `def`, `try` are special, they still remain the same,
although it says that it accepts a closure, but they don't need to be

This adds a new cell path literal syntax for use in any value position,
not just in a context where we expect a cell path.
This can be used to assign to a variable and then later use that
variable as a cell path.

```
> let cell_path = $.a.b
> {a: {b: 3}} | get $cell_path

## 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
in https://github.com/nushell/nushell/issues/8311 and the discord
server, the idea of moving the default banner from the `rust` source to
the `nushell` standar library has emerged 😋
however, in order to do this, one need to have access to all the
variables used in the default banner => all of them are accessible
because known constants, except for the startup time of the shell, which
is not anywhere in the shell...
#### this PR adds exactly this, i.e. the new `startup_time` to the `$nu`
variable, which is computed to have the exact same value as the value
shown in the banner.
## the changes
in order to achieve this, i had to
- add `startup_time` as an `i64` to the `EngineState` => this is, to the
best of my knowledge, the easiest way to pass such an information around
down to where the banner startup time is computed and where the `$nu`
variable is evaluated
- add `startup-time` to the `$nu` variable and use the `EngineState`
getter for `startup_time` to show it as a `Value::Duration`
- pass `engine_state` as a `&mut`able argument from `main.rs` down to
`repl.rs` to allow the setter to change the value of `startup_time` =>
without this, the value would not change and would show `-1ns` as the
default value...
- the value of the startup time is computed in `evaluate_repl` in
`repl.rs`, only once at the beginning, and the same value is used in the
default banner 👌
# User-Facing Changes
one can now access to the same time as shown in the default banner with
```bash
$nu.startup-time
```
# Tests + Formatting
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- 🟢 `cargo test --workspace`
# After Submitting
```
$nothing
```
Add two rows in `$nu`, `$nu.is-interactive` and `$nu.is-login`, which
are true when nu is run in interactive and login mode respectively.
The `-i` flag now behaves a bit more like that of bash's, where the any
provided command or file is run without REPL but in "interactive mode".
This should entail sourcing interactive-mode config files, but since we
are planning on overhauling the config system soon, I'm holding off on
that. For now, all `-i` does is set `$nu.is-interactive` to be true.
About testing, I can't seem to find where cli-args get tested, so I
haven't written any new tests for this. Also I don't think there are any
docs that need updating. However if I'm wrong please tell me.
startup nushell with no config file or env file...
This PR gives the ability to start up nushell easily with no config or
env config files
simply by passing in
```rust
nu -n
```
or
```rust
nu --no-config-file
```
A bonus is that startup times for nushell decreases FIVE fold...
From about > 50ms to less than < 10ms on average on my mac
This will enable Part II which will hopefully be the ability to
to send this flag into the nu! macro and turn off loading of the config
files...
Remember when config files are enabled the nu-cmd-lang tests fail
because the
commands in the config files are a superset of the commands in
nu-cmd-lang...
In my preliminary tests before by zeroing out the config files the
nu-cmd-lang tests passed...
Independent of the cratification efforts I have always wanted a way
anyway to turn off loading
the config files when starting up nushell... So this accomplishes that
task...

# Description
The `ShellError` enum at the moment is kind of messy.
Many variants are basic tuple structs where you always have to reference
the implementation with its macro invocation to know which field serves
which purpose.
Furthermore we have both variants that are kind of redundant or either
overly broad to be useful for the user to match on or overly specific
with few uses.
So I set out to start fixing the lacking documentation and naming to
make it feasible to critically review the individual usages and fix
those.
Furthermore we can decide to join or split up variants that don't seem
to be fit for purpose.
**Everyone:** Feel free to add review comments if you spot inconsistent
use of `ShellError` variants.

# Description
This PR adds an alternative alias implementation. Old aliases still work
but you need to use `old-alias` instead of `alias`.
Instead of replacing spans in the original code and re-parsing, which
proved to be extremely error-prone and a constant source of panics, the
new implementation creates a new command that references the old
command. Consider the new alias defined as `alias ll = ls -l`. The
parser creates a new command called `ll` and remembers that it is
actually a `ls` command called with the `-l` flag. Then, when the parser
sees the `ll` command, it will translate it to `ls -l` and passes to it
any parameters that were passed to the call to `ll`. It works quite
similar to how known externals defined with `extern` are implemented.
The new alias implementation should work the same way as the old
aliases, including exporting from modules, referencing both known and
unknown externals. It seems to preserve custom completions and pipeline
metadata. It is quite robust in most cases but there are some rough
edges (see later).

https://github.com/nushell/nushell/issues/6048
# User-Facing Changes
Since aliases are now basically commands, it has some new implications:
1. `alias spam = "spam"` (requires command call)
* **workaround**: use `alias spam = echo "spam"`
2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than
once)
* **workaround**: use different name (commands also have this
limitation)
4. `alias ls = (ls | sort-by type name -i)`
* **workaround**: Use custom command. _The common issue with this is
that it is currently not easy to pass flags through custom commands and
command referencing itself will lead to stack overflow. Both of these
issues are meant to be addressed._
5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc.
* Should we treat the aliases as commands or should they be separated
from regular commands?
6. Needs better error message and syntax highlight for recursed alias
(`alias f = f`)
7. Can't create alias with the same name as existing command (`alias ls
= ls -a`)
* Might be possible to add support for it (not 100% sure)
8. Standalone `alias` doesn't list aliases anymore
9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay
use` won't work)
* TODO: Needs a better error message when attempting to do so

# Description
this PR adds, when it is defined in the `examples` method of the
`Command` implementations, the output of the examples to the output of
the `help` command.
this PR
- only modifies `crates/nu-engine/src/documentation.rs` and the
`get_documentation` function
- defines a new `WD` constant to print a **W**hite **D**immed `...`
- a `match` statement at the end of the example loop to
- print a white dimmed `...` when the example is not set, i.e. set to
`None` in the `examples` method of the `Command` implementation of a
command
- pretty print the output of the associated example `Value` when it has
been defined

# Description
`bytes starts-with` converts the input into a `Value` before running
.starts_with to find if the binary matches. This has two side effects:
it makes the code simpler, only dealing in whole values, and simplifying
a lot of input pipeline handling and value transforming it would
otherwise have to do. _Especially_ in the presence of a cell path to
drill into. It also makes buffers the entire input into memory, which
can take up a lot of memory when dealing with large files, especially if
you only want to check the first few bytes (like for a magic number).
This PR adds a special branch on PipelineData::ExternalStream with a
streaming version of starts_with.
# User-Facing Changes
Opening large files and running bytes starts-with on them will not take
a long time.
# 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
# Drawbacks
Streaming checking is more complicated, and there may be bugs. I tested
it with multiple chunks with string data and binary data and it seems to
work alright up to 8k and over bytes, though.
The existing `operate` method still exists because the way it handles
cell paths and values is complicated. This causes some "code
duplication", or at least some intent duplication, between the value
code and the streaming code. This might be worthwhile considering the
performance gains (approaching infinity on larger inputs).
Another thing to consider is that my ExternalStream branch considers
string data as valid input. The operate branch only parses Binary
values, so it would fail. `open` is kind of unpredictable on whether it
returns string data or binary data, even when passing `--raw`. I think
this can be a problem but not really one I'm trying to tackle in this
PR, so, it's worth considering.
Fixes#7615
# Description
When calling external commands, we create a table from the pipeline data
to handle external commands expecting paginated input. When a binary
value is made into a table, we convert the vector of bytes representing
the binary bytes into a pretty formatted string. This results in the
pretty formatted string being sent to external commands instead of the
actual binary bytes. By checking whether the stdout of the call is being
redirected, we can decide whether to send the raw binary bytes or the
pretty formatted output when creating a table command.
# User-Facing Changes
When passing binary values to external commands, the external command
will receive the actual bytes instead of the pretty printed string. Use
cases that don't involve piping a binary value into an external command
are unchanged.

# Description
The point of this command is to allow you to be able to format ints,
floats, filesizes, and strings with an alignment, padding, and a fill
character, as strings. It's meant to take the place of `str lpad` and
`str rpad`.
```
> help fill
Fill and Align
Search terms: display, render, format, pad, align
Usage:
> fill {flags}
Flags:
-h, --help - Display the help message for this command
-w, --width <Int> - The width of the output. Defaults to 1
-a, --alignment <String> - The alignment of the output. Defaults to Left (Left(l), Right(r), Center(c/m), MiddleRight(cr/mr))
-c, --character <String> - The character to fill with. Defaults to ' ' (space)
Signatures:
<number> | fill -> <string>
<string> | fill -> <string>
Examples:
Fill a string on the left side to a width of 15 with the character '─'
> 'nushell' | fill -a l -c '─' -w 15
Fill a string on the right side to a width of 15 with the character '─'
> 'nushell' | fill -a r -c '─' -w 15
Fill a string on both sides to a width of 15 with the character '─'
> 'nushell' | fill -a m -c '─' -w 15
Fill a number on the left side to a width of 5 with the character '0'
> 1 | fill --alignment right --character 0 --width 5
Fill a filesize on the left side to a width of 5 with the character '0'
> 1kib | fill --alignment middle --character 0 --width 10
```

As usual, Rust optimizes a bit less if more function boundaries are
introduced.
However, in my opinion, being able to comprehend the decision tree beats
a couple of string allocations.

# Description
This PR changes the old performance logging with `Instant` timers. I'm
not sure if this is the best way to do it but it does help reveal where
time is being spent on startup. This is what it looks like when you
launch nushell with `cargo run -- --log-level info`. I'm using the
`info` log level exclusively for performance monitoring at this point.
## After Startup
Since you're in the repl, you can continue running commands. Here's the
output of `ls`, for instance.
Note that the above screenshots are in debug mode, so they're much
slower than release.

# Description
_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_
I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time
For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`
When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.
Please let me know If I need to make any changes and I will be happy to
do it.
# User-Facing Changes
A new flag (`--progress` `-p`) was added to the `save` command
Examples:
```nu
fetch https://github.com/torvalds/linux/archive/refs/heads/master.zip | save --progress -f main.zip
fetch https://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso | save --progress -f main.zip

src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.
I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...
now that @rgwood has landed benches I want
to start experimenting with benchmarks related
to the parser.
For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...
Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...
Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...
It will also enable other crates going forward to
use BufferedReader. Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".
Add recursion limit to `def` and `block`.
Summary of this PR , it will detect if `def` call itself or not .
Then execute by using `stack` which I think best choice to use with this
design and core as it is available in all crates and mutable and
calculate the recursion limit on calling `def`.
Set 50 as recursion limit on `Config`.
Add some tests too .

The ordering of flags in `nu --help` was a bit of a mess; I think it
grew organically over time. Related commands (like
`--config`/`--env-config`/`--plugin-config`) weren't grouped together,
common flags weren't near the top, and we weren't following alphabetical
ordering.
### Before
```bash
Flags:
-h, --help - Display the help message for this command
--stdin - redirect standard input to a command (with `-c`) or a script file
-l, --login - start as a login shell
-i, --interactive - start as an interactive shell
-v, --version - print the version
--testbin <String> - run internal test binary
-c, --commands <String> - run the given commands and then exit
--config <String> - start with an alternate config file
--env-config <String> - start with an alternate environment config file
--log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
--log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
-e, --execute <String> - run the given commands and then enter an interactive shell
-t, --threads <Int> - threads to use for parallel commands
-m, --table-mode <String> - the table mode to use. rounded is default.
--plugin-config <String> - start with an alternate plugin signature file
```
### After
```bash
Flags:
-h, --help - Display the help message for this command
-c, --commands <String> - run the given commands and then exit
-e, --execute <String> - run the given commands and then enter an interactive shell
-i, --interactive - start as an interactive shell
-l, --login - start as a login shell
-m, --table-mode <String> - the table mode to use. rounded is default.
-t, --threads <Int> - threads to use for parallel commands
-v, --version - print the version
--config <String> - start with an alternate config file
--env-config <String> - start with an alternate environment config file
--plugin-config <String> - start with an alternate plugin signature file
--log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
--log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
--stdin - redirect standard input to a command (with `-c`) or a script file
--testbin <String> - run internal test binary
```
The new ordering:
1. Groups commands with short flags together, sorted alphabetically by
short flag
1. Groups commands with only long flags together, sorted alphabetically
(with the exception of `--plugin-config` so we can keep related flags
together)
Conveniently, this puts the very commonly used `-c` at the top and the
very rarely used `--testbin` at the bottom.

## Command fixes
- Fix abuse of `Span::test_data()` in `query_xml`
- Fix abuse of `Span::test_data()` in `term size`

# User-Facing Changes
Some commands may now provide more helpful spans for downstream use in
errors
# Description
Purely for consistency, various remaining instances of `$nothing`
(almost all of which were in test code) have been changed to `null`.
Now, the only place that refers to `$nothing` is the parser code which
implements it.
# User-Facing Changes
The default config.nu now uses `null` in certain places where it used
`$nothing`.

# Description
This PR changes some commands that previously accepted row conditions
(like `$it > 5`) as parameter to accept closures instead. The reasons
are:
a) The commands would need to move into parser keywords in the future
while they feel more like commands to be implemented in Nushell code as
a part of standard library.
b) In scripts, it is useful to store the predicate condition in a
variable which you can't do with row conditions.
c) These commands are not used that often to benefit enough from the
shorter row condition syntax
# User-Facing Changes
The following commands now accept **closure** instead of a **row
condition**:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`
This is a part of an effort to move away from shape-directed parsing.

# Description
While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
val: a,
span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

This removes the `&&` and `||` operators. We previously supported by
`&&`/`and` and `||`/`or`. With this change, only `and` and `or` are

# Description
fixes#7384
This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.
# User-Facing Changes
`else` block will no longer capture variables as it will now use a block
instead of a closure.

This fix changes pipelines to allow them to actually be empty. Mapping
over empty pipelines gives empty pipelines. Empty pipelines immediately
return `None` when iterated.

there are other cases where we still use it.

We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.
Operator precedence
`and` > `xor` > `or`
Added logic and precedence tests.
# Description
As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.
And if the command is executed directly like: `cat tmp`, the result
won't change.
Fixes: #6816Fixes: #3980
Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.
If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency.
- More understandable for newcomers, that these commands are no special to others.
- `?` syntax did not really aprove readability. For me it made it worse.
- We can reserve `?` syntax for any other nushell feature.

* Add plugin CLI argument
While working on supporting CustomValues in Plugins I stumbled upon the
test utilities defined in [nu-test-support][nu-test-support]
and thought these will come in handy, but they end up being outdated.
They haven't been used or since engine-q's was merged, so they are
currently using the old way engine-q handled plugins, where it would
just look into a specific folder for plugins and call them without
signatures or registration. While fixing that I realized that there is
currently no way to tell nushell to load and save signatures into a
specific path, and so those integration tests could end up potentially
conflicting with each other and with the local plugins the person
running them is using.
So this adds a new CLI argument to specify where to store and load
plugin signatures from
I am not super sure of the way I implemented this, mainly
I was a bit confused about the distinction between
[src/config_files.rs][src/config_files.rs] and
[crates/nu-cli/src/config_files.rs][crates/nu-cli/src/config_files.rs].
Should I be moving the plugin loading function from the `nu-cli` one to
the root one?

* Add test for passing binary data through externals
This change adds an ignored test to confirm that binary data is passed

the fix.
To assist in platform agnostic testing of binary data a couple of
additional testbins were added to allow testing on `Value::Binary` inside
`ExternalStream`.
* Support binary data to stdin of run-external
Prior to this change, any pipeline producing binary data (not detected
as string) then feed into an external would be ignored due to
run-external only supporting `Value::String` on stdin.
This change adds binary stdin support for externals allowing something
like this for example:
〉^cat /dev/urandom | ^head -c 1MiB | ^pv -b | ignore
1.00MiB
This would previously output `0.00 B [0.00 B/s]` due to the data not
being pushed to stdin at each stage.
