# Description
Close: #10278
This pr introduces `o>>`, `e>>`, `o+e>>` to allow redirection to append
to a file.
Examples:
```nushell
echo abc o>> a.txt
echo abc o>> a.txt
cat asdf e>> a.txt
cat asdf e>> a.txt
cat asdf o+e>> a.txt
```
~~TODO:~~
~~1. currently internal commands with `o+e>` redirect to a variable is
broken: `let x = "a.txt"; echo abc o+e> $x`, not sure when it was
introduced...~~
~~2. redirect stdout and stderr with append mode doesn't supported yet:
`cat asdf o>>a.txt e>>b.ext`~~
~~For these 2 items, I'd like to fix them in different prs.~~
Already done in this pr
# Description
This PR addresses issue with cp brough up on
[discord](https://discord.com/channels/601130461678272522/614593951969574961/1177669443917189130)
where target of cp is not correctly expanded.
If one has directory `test` with file `file.txt` in it then the
following command (in one line or inside a `do` block):
```nu
cd test; let file = 'copy.txt'; cp file.txt $file
```
will create a `copy.txt` in `.` not in `test` instead. This happens
because target of `cp` is a variable which is not expanded unlike a
string literal
# User-Facing Changes
`cp` will correctly parse realative target paths

# Description
This PR enables a new feature that shows which externals are found in
your path via the syntax highlighter as you type.
This idea could use some improvement where it caches the items in your
path and on some trigger, expires that cache and creates a new on. Right
now, all it does is call the `which` crate on every character you type.
This could be problematic if you have hundreds of paths in your PATH or
if some of your paths in your Path point to extraordinarily slow file
systems. WSL pointing to Windows comes to mind. Either way, I've thrown
it up here for people to try and provide feedback. I think the novelty
of showing what is valid and what isn't is pretty cool. I believe
fish-shell also does this, IIRC.

Fix release and nightly build workflow:
https://github.com/nushell/nightly/issues/15
I think the `mv` command in v0.87.1 still has some bugs, when downgrade
to v0.86 everything works as expected
# Description
Fixes: #10271
Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```
This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```
## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command
These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.
### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.
# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa
cc
```
## After
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
╭───┬───╮
│ 0 │ 5 │
│ 1 │ 2 │
╰───┴───╯
```
BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error: × Can't make stderr redirection twice
╭─[entry #1:1:1]
1 │ echo a e> a.txt e> a.txt
· ─┬
· ╰── try to remove one
╰────
❯ echo a o> a.txt o> a.txt
Error: × Can't make stdout redirection twice
╭─[entry #2:1:1]
1 │ echo a o> a.txt o> a.txt
· ─┬
· ╰── try to remove one
╰────
```
# Description
Closes: #7260
About the change:
When we make an internalcall, and meet a `switch` (Flag.arg is None),
nushell will try to see if the switch is called like `--xyz=false` , if
that is true, `parse_long_flag` will return relative value.
# User-Facing Changes
So after the pr, the following would be possible:
```nushell
def build-imp [--push, --release] {
echo $"Doing a build with push: ($push) and release: ($release)"
}
def build [--push, --release] {
build-imp --push=$push --release=$release
}
build --push --release=false
build --push=false --release=true
build --push=false --release=false
build --push --release
build
```

# Description
Further work towards the goal that we can make `Record`'s field private
and experiment with different internal representations
## Details
- Use inplace record iter in `nu-command/math/utils`
- Guarantee that existing allocation can be reused
- Use proper record iterators in `path join`
- Remove unnecesary hashmap in `path join`
- Should minimally reduce the overhead
- Unzip records in `nu-command`
- Refactor `query web` plugin to use record APIs
- Use `Record::into_values` for `values` command
- Use `Record::columns()` in `join` instead.
- Potential minor pessimisation
- Not the hot value path
- Use sane `Record` iters in example `Debug` impl
- Avoid layout assumption in `nu-cmd-extra/roll/mod`
- Potential minor pessimisation
- relegated to `extra`, changing the representation may otherwise break
this op.
- Use record api in `rotate`
- Minor risk that this surfaces some existing invalid behavior as panics
as we now validate column/value lengths
- `extra` so things are unstable
- Remove unnecessary references in `rotate`
- Bonus cleanup
# User-Facing Changes
None functional, minor potential differences in runtime. You win some,
you lose some.
# Tests + Formatting
Relying on existing tests
# Description
I'm not sure if "is-terminal" is the best name for this command as there
is also "term size". Uses
[`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal)
which is cross-platform.
Possible alternative names:
* `term is-tty --stdout`
* `term is-tty stdout`
* `term is-terminal stdout`
If multiple streams are provided an error is returned. The error span
covers all arguments as the incompatible one is not known. This may be
new?
Fixes#10517
# User-Facing Changes
* Add `is-terminal` to check if stdin, stdout, or stderr are a terminal
(TTY)
# Tests + Formatting
The nu tests always redirect stdin, stdout, and stderr so a positive
test case is not possible without extra work

- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# After Submitting
The new command will be added automatically

This is still work in progress. But let's start somewhere.
Goal for this being in the repo is to make sure we update it more
frequently than the
https://github.com/nushell/nushell.github.io/tree/main/contributor-book
- Add folder for in-repo developer documentation
- Move PLATFORM_SUPPORT into devdocs
- Move our rust style to devdocs
- Use nushell code formatting in CONTRIBUTING
- Add FAQ file for developers with example questions
- Describe error handling best practices
# Description
`ShellError::FlagNotFound` had a note that said it may be removable so
this PR removes it instead of updating it to named fields per #10700
I can't see this error being used since it was introduced with #4364. I
can't find why or where it was used before that date, though. There was
a large merge with that PR but I can't penetrate the secrets of git to
find out where its earlier history went.

Fix the breaking changes.
Get's rid of some outdated transitive dependencies.
Sadly we need to expose more of `procfs` to `nu-command` based on how
the features of `nu-system` are exposed right now.
Conditional compilation/dependencies from hell included
Supersedes #11101
# Description
Slightly refactors the cell path functions (`insert_data_at_cell_path`,
etc.) for `Value` to fix a few bugs and ensure consistent behavior.
Namely, case (in)sensitivity now applies to lazy records just like it
does for regular `Records`. Also, the insert behavior of `insert` and
`upsert` now match, alongside fixing a few related bugs described below.
Otherwise, a few places were changed to use the `Record` API.
# Tests
Added tests for two bugs:
- `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the
innermost record `c`.
- `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before
this PR, doesn't add the field `b: 2` to each row.
# Description
These make it easy to make a Span that covers an entire argument and the
span of all arguments in a Call.
Call::arguments_span() is useful for errors where a command may accept
arguments or the pipeline, but not both.
Argument::span() is useful for errors where an arguments is incompatible
with one or more other arguments.
In particular, I wish to use this to create an error for an
implementation of #9563 that either allows arguments to set limits:
```nushell
limits set RLIMIT_NOFILE --soft 255 --hard 1024
```
Or pipeline:
```nushell
{name: RLIMIT_NOFILE, soft: 255} | limits set
```
But not both:
```
❯ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5
Error: nu:🐚:incompatible_parameters
× Incompatible parameters.

I've opened this a little prematurely to get some questions answered
before I cleanup the code.
As I started trying to better understand GNUs `mktemp` I've realized its
kind of peculiar and we might want to change its behavior to introduce
it to nushell.
#### quiet and dry run
Does it make sense to keep the `quiet` and `dry_run` flags? I don't
think so. The GNU documentation says this about the dry run flag "Using
the output of this command to create a new file is inherently unsafe, as
there is a window of time between generating the name and using it where
another process can create an object by the same name." So yeah why keep
it? As far as quiet goes, does it make sense to silence the errors in
nushell?
#### other confusing flags
According to the [gnu
docs](https://www.gnu.org/software/coreutils/manual/html_node/mktemp-invocation.html),
the `-t` flag is deprecated and the `-p`/ `--tempdir` are the same flag
with the only difference being `--tempdir` takes an optional path, Given
that, I've broken the `-p` away from `--tempdir`. Now there is one
switch `--tmpdir`/`-t` and one named param `--tmpdir-path`/`-p`.
GNU mktemp
```
-p DIR, --tmpdir[=DIR] interpret TEMPLATE relative to DIR; if DIR is not
specified, use $TMPDIR if set, else /tmp. With
this option, TEMPLATE must not be an absolute name;
unlike with -t, TEMPLATE may contain slashes, but
mktemp creates only the final component
-t interpret TEMPLATE as a single file name component,
relative to a directory: $TMPDIR, if set; else the
directory specified via -p; else /tmp [deprecated]
```
to
nushell mktemp
```
-p, --tmpdir-path <Filepath> # named param, must provide a path
-t, --tmpdir # a switch
```
Is this a terrible idea?
What should I do?

It prevented it from running because "default" wasn't a real table
theme. Now "default" is a synonym of rounded.
Also tweaked the error message when a bad theme name is provided.

# Description
The `into binary` command has a `-c` flag which strips any leading 0s in
the most significant digits to represent the minimal number of bytes,
rather than the system's complete in-memory representation of the input.
However, currently giving 0 as input results in eight 0 bytes even with
the `-c` flag, which is inconsistent with the purpose of the flag.
```nu
❯ : 345678 | into binary
Length: 8 (0x8) bytes | printable whitespace ascii_other non_ascii
00000000: 4e 46 05 00 00 00 00 00 NF•00000
❯ : 345678 | into binary -c
Length: 3 (0x3) bytes | printable whitespace ascii_other non_ascii
00000000: 4e 46 05
❯ : 0 | into binary
Length: 8 (0x8) bytes | printable whitespace ascii_other non_ascii
00000000: 00 00 00 00 00 00 00 00 00000000
❯ : 0 | into binary -c
Length: 8 (0x8) bytes | printable whitespace ascii_other non_ascii
00000000: 00 00 00 00 00 00 00 00 00000000
```
This change fixes this behavior so that if the entire input results in
all 0 bytes, only a single 0 byte is returned.
```nu
❯ : ~/src/nushell/target/aarch64-linux-android/debug/nu -c '0 | into binar
y -c'
Length: 1 (0x1) bytes | printable whitespace ascii_other non_ascii
00000000: 00
```
# User-Facing Changes
Values which result in all null bytes will be truncated to a single byte
when `-c` is given. This could potentially be considered a breaking
change if this behavior was relied upon in some way.
