The value rendering code in explore is _very_ flexible; values can be
rendered with orientation `Top`, `Left`, `Bottom`, or `Right`. The
default is `Top` for tables (header at the top) and `Left` for records
(header on the left).
This PR removes `Bottom` and `Right`; they are largely untested,
probably used by nobody, and they complicate the rendering code.
## Testing Performed
I've manually confirmed that tables and records still render the same
ass before, and the `t`/transpose command still works.

> [!NOTE]
> This PR description originally used examples where the `generator`
closure returned a list. It has since been updated to use records
instead.
The `unfold` command allows users to dynamically generate streams of
data. The stream is generated by repeatedly invoking a `generator`
closure. The `generator` closure accepts a single argument and returns a
record containing two optional keys: 'out' and 'next'. Each invocation,
the 'out' value, if present, is added to the stream. If a 'next' key is
present, it is used as the next argument to the closure, otherwise
generation stops.
The name "unfold" is borrowed from other functional-programming
languages. Whereas `fold` (or `reduce`) takes a stream of values and
outputs a single value, `unfold` takes a single value and outputs a
stream of values.
### Examples
A common example of using `unfold` is to generate a fibbonacci sequence.
See
[here](6ffdac103c/src/sources.rs (L65))
for an example of this in rust's `itertools`.
```nushell
> unfold [0, 1] {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} } | first 10
───┬────
0 │ 0
1 │ 1
2 │ 1
3 │ 2
4 │ 3
5 │ 5
6 │ 8
7 │ 13
8 │ 21
9 │ 34
───┴────
```
This command is particularly useful when consuming paginated APIs, like
Github's. Previously, nushell users might use a loop and buffer
responses into a list, before returning all responses at once. However,
this behavior is not desirable if the result result is very large. Using
`unfold` avoids buffering and allows subsequent pipeline stages to use
the data concurrently, as it's being fetched.
#### Before
```nushell
mut pages = []
for page in 1.. {
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
$pages = ($pages | append $resp)
if ($resp | length) < $PAGE_SIZE {
break
}
}
$pages
```
#### After
```nu
unfold 1 {|page|
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
if ($resp | length) < $PAGE_SIZE {
{out: $resp}
} else {
{out: $resp, next: ($page + 1)}
}
}
```

Closes#10441
Uses `String::to_lowercase()` when the file's extension `ext` is parsed
to allow `from_decl(format!("from {ext}"))` to return the desired output
regardless of extension case.
It doesn't work with sqlite files since those are handled earlier in the
parsing but I think is good- since there's no standard file extension
used by sqlite so a user will likely want case sensitivity in that case.
This also has the (possibly undesired) effect of making `open`
completely case insensitive, e.g. `open foo.JSON` will work on a file
named `foo.json` and vice versa. This is good on Windows as it treats
`foo.json` and `foo.JSON` as the same file, but may not be the desired
behaviour on Unix.
If this behaviour is undesired I assume it would be fixed with a
`#[cfg(not(unix))]` attribute on the `to_lowercase()` operation but that
produces slightly "uglier" code that I didn't wish to submit unless
necessary.
old behaviour:
new behaviour:
# User-Facing Changes

This pr closes#10521.
# Description
The default prompt by nushell will replace `$nu.home-path` with `~`.
E.g. for a user named `user`, `/home/user` would become `~`. This also
works with sub paths, e.g. `/home/user/docs` would become `~/docs`.
The issue is that this replacement was a tad overzealous. A path like
`/home/user-with-suffix` would become `~-with-suffix`. This PR fixes the
issue by updating the home path detection logic.
# User-Facing Changes
The bugged behavior no longer occurs.
# Tests + Formatting
* `cargo` checks were not performed as this does not touch rust.
* The updated logic was tested against
[elvish](https://github.com/elves/elvish)'s path replacement logic, for
~10,000 randomly selected folders on a linux server. All paths were
processed the same.

# User-Facing Changes
You can now either pass a string with the name of the executable or a
list with the executable and any flags to
`$env.config.buffer_editor`/`$env.EDITOR`/`$env.VISUAL`
Both the external buffer editor of reedline (by default bound to
`Ctrl-o`) and the commands `config nu` and `config env` will respect
those variables in the following order:
1. `$env.config.buffer_editor`
2. `$env.EDITOR`
3. `$env.VISUAL`
Example:
```
$env.EDITOR = "nvim" # The system-wide EDITOR is neovim
$env.config.buffer_editor = ["vim" "-p2"] # Force vim to open two tabs (not particularly useful)
$env.config.buffer_editor = null # Unset `buffer_editor` -> Uses `$env.EDITOR` ergo nvim

# Description
Support keyboard enhancement protocol as implemented by Kitty console,
hence Kitty protocol.
This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.
For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.
# User-Facing Changes
This adds `use_kitty_protocol` config which defaults to false. When set
to `true`, it enables kitty protocol on the line editor when supported,
or else it warns.

More incremental `explore` improvements!
This PR removes the `show_cursor` config from the `explore` command, in
favour of always using the background colour to highlight the selected
cell. I believe this is a better default and I'd like to remove the
`show_cursor` functionality entirely as part of the effort to simplify
`explore`.
The style for selected cells is still configurable. I went with light
blue for the default background colour, it looks OK to me.

Closes#5436
When I opened this issue more than a year ago, I mainly wanted the
following capacity: easily access the full env and have the hability to
update it when a new version of `nushell` comes out.
With this PR I can now do the following:
```nu
source-env ~/.config/nushell/defaults/env.nu
source ~/.config/nushell/defaults/config.nu
# Update nushell default config & env file (run this after a version update)
def update-defaults [] {
config env --default | save -f ~/.config/nushell/defaults/env.nu
config nu --default | save -f ~/.config/nushell/defaults/config.nu
}
```
Which is more than enough for me. Along with `nushell` respecting the
XDG spec on macOS (`dirs-next` should be banned for CLI tools on macOS),
this should be one of the last hurdle before fully switching for me!

### Update winget submission workflow include only default msi files:
---
The new release workflow after
https://github.com/nushell/nushell/pull/10457 will add full featured
packages like: `nu-*-x86_64-windows-msvc-full.msi` and
`nu-*-aarch64-windows-msvc-full.msi` (A release preview could be found
here: https://github.com/nushell/nightly/releases/tag/nightly-6a2fd91 )
and this change will make sure only the default packages will be
included just the same as before to make sure that nothing will be
broken.
BTW: Due to lots of changes made recently about the release workflow, I
will stand-by for the next release.
# Description
Fix type checking in arguments default values not adhering to subtyping
rules
Currently following examples produce a parse error:
```nu
def test [ --qwe: record<a: int> = {a: 1 b: 1} ] { }
def test [ --qwe: list<any> = [ 1 2 3 ] ] { }
```
despite types matching. Type equality check is replaced with subtyping
check and everything parses fine:
# User-Facing Changes
Default values of flag arguments type checking behavior is in line with
`let` statements
# Description
This PR fixes#9702 on the side of parse. I.e. input/output types in
signature and type annotations in `let` now should correctly parse with
type annotations that contain commas and spaces:
# User-Facing Changes
Return values and let type annotations now can contain stuff like
`table<a: int b: record<c: string d: datetime>>` e.t.c
fixes#10455
@KAAtheWiseGit, I'm sorry, I didn't mean to block your first PR #10461,
didn't see you had submitted it till I got around to submitting this. If
you want to incoporate useful ideas from this PR into yours, I do not
mind deferring to you.
# Description
Changes made in `datetime-diff`:
* Initialize millisecond and microsecond fields in `$current`, to fix
the error when borrow needs to refer to them.
* Fix `borrow_nanoseconds` to borrow from seconds, not from (unused)
microseconds.
* Added error check to insist that first argument is >= second argument.
`datetime-diff` doesn't represent negative durations correctly (it tries
to borrow out of the year, resulting in negative year and positive all
other fields). We don't currently have a use case requiring negative
durations.
* Add comments so help is a bit clearer (I was surprised that the first
argument, named `$from` was actually supposed to be the *later*
datetime. The order of arguments is reasonable (reminiscent of <later>
<minus> <earlier>), so I just changed the param name to match its
purpose.
Changes made in `pretty-print-duration`:
* changed type of argument from `duration` to `record`. (it's not clear
why Nu was not complaining about this!)
* changed test for skipping a clause from `> 0` to `!= 0`. Even though
`datetime-diff` won't present a negative field in the record, user might
call `pretty-print-duration` with one, might as well handle it. (but I
think `hour:-2` will be rendered as `-2hr`, not `-2hrs`...).
* added help and an example.

# Description
this PR will fix the public API of the standard library by removing the
type annotations from public boolean switches.
1. the signature before
```nushell
clip [--silent: bool, --no-notify: bool, --no-strip: bool, --expand (-e): bool, --codepage (-c): int]
```
2. the signature after
```nushell
clip [--silent, --no-notify, --no-strip, --expand (-e), --codepage (-c): int]
```

# Description
Fixes: #10450
This pr differentiating between `--x: bool` and `--x`
Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x # not allowed, you need to parse a value to the flag.
a # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```
For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo # output false
foo --option # not allowed, you need to parse a value to the flag.
foo --option true # output true
```
# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```
Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.
## Update: one more breaking change to help on #7260
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

## Description
This PR uses environment variables to enable and set a transient prompt,
which lets you draw a different prompt once you've entered a command and
you've moved on to the next line. This is useful if you have a fancy
two-line prompt with a bunch of info about time and git status that you
don't really need in your scrollback buffer.
Here's a screenshot. You can see how my usual prompt has two lines and
would take up a lot more space if every past command also used the full
prompt, but reducing past prompts to `🚀` or `>` makes it take up less
space.
I added the following lines to my `env.nu` to get that rocket as the
prompt initially:
```nu
$env.TRANSIENT_PROMPT_COMMAND = {|| "" }
$env.TRANSIENT_PROMPT_INDICATOR = {|| open --raw "~/.prompt-indicator" }
$env.TRANSIENT_PROMPT_INDICATOR_VI_INSERT = $env.TRANSIENT_PROMPT_INDICATOR
```
## User-Facing Changes
If you want to change a segment of the prompt, set the corresponding
`TRANSIENT_PROMPT_*` variable.
<!-- 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.
-->
## Problems/Things to Consider:
- The transient prompt clones the `Stack` at the very beginning of the
session and keeps that around. I'm not sure if that could cause
problems, but if so, it could probably take an `Arc<State>` instead.
- This isn't truly a problem, but now there's even more environment
variables, which is kinda annoying.
- There might be some performance issues with creating a new
`NushellPrompt` object and cloning the `Stack` for every segment of the
transient prompt. What's more, the transient prompt is added to the
`Reedline` object whether or not the user has enabled transient prompt,
so if there are indeed performance issues, simply disabling the
transient prompt won't help.
- Perhaps instead of a separate `TRANSIENT_PROMPT_INDICATOR_VI_INSERT`
and `TRANSIENT_PROMPT_INDICATOR_VI_NORMAL`, `TRANSIENT_PROMPT_INDICATOR`
could be used for both (if it exists). Insert and normal mode don't
really matter for previously entered commands.

When parse_range get an item like ((((1..2)))) it would try to parse
"((((1" with a long chain of recursive parsers, namely:
- parse_value
- parse_paren_expr
- parse_full_cell_path
- parse_block
- parse_pipeline
- parse_builtin_commands
- parse_expression
- parse_math_expression
- parse_value
- ...
where `parse_paren_expr` calls `parse_range` in turn. Because at any
time in the chain `parse_paren_expr` can call `parse_range`, which will
then continue the chain, we get quadratic number of function calls, each
linear on the size of the input
By checking with the lexer that the parens are matched, we prevent the
long chain from being called on unmatched braces. Now, this is still
more quadratic than it needs to be, to fix that, we should process
parens only once, instead of on each recursive call

# Other notes
Found using the fuzzer, by setting a timeout on max run-time. It also
found a stack-overflow on too many parentheses, which this doesn't fix.
# Description
This PR fixes a bug found by @kubouch where `$nu` is not evaluated as a
constant when the `--ide-check` parameter is passed to nushell for the
LSP-like functionality. Not quite sure my changes are proper but it
seems to work!

# Description
While reviewing #10350 I noticed that a `HashSet<usize>` was used to
deduplicate the incoming rows, which are then sorted after cloning to a
separate `Vec`. This sounds like a candidate for a `BTreeSet` which
guarantees the ordering.
In the process I removed some dead code.
- Use `BTreeSet` instead of `HashSet`
- Remove dead `skip` logic
- Use `BTreeSet` directly in `NthIterator`
- Consume `BTreeSet` through `Peekable<IntoIter>`
Factor the big parts into separate files:
- `state_delta.rs`
- `state_working_set.rs`
- smaller `usage.rs`
This required adjusting the visibility of several parts.
Makes `StateDelta` transparent for the module.
Trying to reduce visibility in some other places
# Description
This PR should close#10085

# User-Facing Changes
This means a user will see `FileNotFound` instead of `DirectoryNotFound`
which is more meaning full to the user.

# Description
Unify the logic between `nu!` and `nu_with_std!`.
The inner code actually does not contain any variadic components. So it
can safely be abstracted into a function.
Similarly simplify the variadic to an array in `nu_with_plugin!`
This also seems to simplify the codegen for tests.
