# Description
Fixes: #13460
The issue is caused by `try_exists` method on path, it will return
`Err(NotADirectory)` if user tried to check for a path under a regular
file.
To fix it, I think it's ok to use `exists` rather than `try_exists`,
although
[Path::exists()](https://doc.rust-lang.org/std/path/struct.Path.html#method.exists)
only checks whether or not a path was both found and readable. I think
it's ok, and we can add this information under `extra_description`.
# User-Facing Changes
The following code will no longer raise error:
```
touch a; 'a/b' | path exists
```
# Tests + Formatting
Added 1 test.
# Description
Add `metadata access`, which allows accessing/inspecting the metadata of
a stream in a closure.
```nu
ls | metadata access {|meta|
...
}
```
- The metadata is provided as an argument to the closure, identical to
the record obtained with `metadata` command.
- `metadata access` passes its input stream into the closure as it is.
- Within the closure, both the metadata and the stream are available.
The closure may modify, collect or pass the stream as it is.
# Motivation
- Without this command, nu code can't act on metadata without losing the
stream, use cases requiring both the stream and metadata must be
implemented either as a built-in or a plugin.
- This command allows users to enhance presentation of data, similar to
`table` coloring the output of `ls`.
# Description
Fixes a bug in the IR for `try` to match that of the regular evaluator
(continuing from #13515):
```nushell
# without IR:
try { ^false } catch { 'caught' } # == 'caught'
# with IR:
try { ^false } catch { 'caught' } # error, non-zero exit code
```
In this PR, both now evaluate to `caught`. For the implementation, I had
to add another instruction, and feel free to suggest better
alternatives. In the future, it might be possible to get rid of this
extra instruction.
# User-Facing Changes
Bug fix, `try { ^false } catch { 'caught' }` now works in IR.
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```
Before this would give:
```
╭───┬──╮
│ 0 │ │
│ 1 │ │
╰───┴──╯
```
Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input
× Eval block failed with pipeline input
╭─[entry #1:1:2]
1 │ [1 2] | each { ^false }
· ┬
· ╰── source value
╰────
Error: nu:🐚:non_zero_exit_code
× External command had a non-zero exit code
╭─[entry #1:1:17]
1 │ [1 2] | each { ^false }
· ──┬──
· ╰── exited with code 1
╰────
```
This PR fixes#12874, fixes#5960, fixes#10856, and fixes#5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes#8569).
# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).
# Tests
Added a few tests.
# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).
# Description
The content-type was not being handled appropriately when sending
requests with a string value.
# User-Facing Changes
- Passing a string value through a pipeline with a content-type set as
metadata is handled correctly
- Passing a string value as a parameter with a content-type set as a
flag is handled correctly.
# Description
After looking at #13751 I noticed that the config setting
`use_grid_icons` seems out of place. So, I removed it from the config
and made it a parameter to the `grid` command.
# Description
The existing code uses exact matches on content type. This can caused
things like "application/json; charset=utf-8" that contain a charset not
using send_json method.
NOTE: The charset portion in the above example would still be ignored as
we rely on serde and the client library to control the encoding, it is
still better to catch the json case.

# Description
This pr addresses the comment:
https://github.com/nushell/nushell/issues/11791#issuecomment-2308384155
It's caused by if the last row have a very different format to the first
row, the value of `end_char` will exceed the `line_char_boundaries`.
Adding a guard for it should avoid such panic.
# User-Facing Changes
The following code should no longer panic:

trace_nu_plugin = '0.3.1' # A wrapper to trace Nu plugins
nu_plugin_bash_env = '0.13.0' # Nu plugin bash-env
nu_plugin_from_sse = '0.4.0' # Nushell plugin to convert a HTTP server sent event stream to structured data
... and 90 crates more (use --limit N to see more)" | detect columns -n --guess
```
# Tests + Formatting
Added 1 test.
# Description
This changes the behavior of `tee` to be more transparent when given a
value that isn't a list or range. Previously, anything that wasn't a
byte stream would converted to a list stream using the iterator
implementation, which led to some surprising results. Instead, now, if
the value is a string or binary, it will be treated the same way a byte
stream is, and the output of `tee` is a byte stream instead of the
original value. This is done so that we can synchronize with the other
thread on collect, and potentially capture any error produced by the
closure.
For values that can't be converted to streams, the closure is just run
with a clone of the value instead on another thread. Because we can't
wait for the other thread, there is no way to send an error back to the
original thread, so instead it's just written to stderr using
`report_error_new()`.
There are a couple of follow up edge cases I see where byte streams
aren't necessarily treated exactly the same way strings are, but this
should mostly be a good experience.
Fixes#13489.
# User-Facing Changes
Breaking change.
- `tee` now outputs and sends string/binary stream for string/binary
input.
- `tee` now outputs and sends the original value for any other input
other than lists/ranges.
# Tests + Formatting

# Description
`cargo` somewhat recently gained the capability to store `lints`
settings for the crate and workspace, that can override the defaults
from `rustc` and `clippy` lints. This means we can enforce some lints
without having to actively pass them to clippy via `cargo clippy -- -W
...`. So users just forking the repo have an easier time to follow
similar requirements like our CI.
## Limitation
An exception that remains is that those lints apply to both the primary
code base and the tests. Thus we can't include e.g. `unwrap_used`
without generating noise in the tests. Here the setup in the CI remains
the most helpful.
## Included lints
- Add `clippy::unchecked_duration_subtraction` (added by #12549)
# User-Facing Changes
Running `cargo clippy --workspace` should be closer to the CI. This has
benefits for editor configured runs of clippy and saves you from having
to use `toolkit` to be close to CI in more cases.

# Description

# Description
Closes#13677
Remove the command `str deunicode`, as it has a narrow application, is
loosely defined by the data provided by the `deunicode` crate and thus a
stabilization liability post-1.0.
Furthermore the data to perform the look-up is quite substantial.
Removing the command and the `deunicode` dependency saves 0.9 MB of
binary data in release mode (~ 2% of total)
(checked via `cargo bloat --release` for a linux x86 build)
# User-Facing Changes
The `str deunicode` command recently added in #13270 is gone
Mistakes have been made. I forgot about a bunch of `todo`s in the helper

## Description
Reworks the `decode`/`encode` commands by adding/changing the following
bases:
- `base32`
- `base32hex`
- `hex`
- `new-base64`
The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.
All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.
## Example usage
```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```
```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000: 74 65 73 74 test
```
## User-Facing Changes
- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.
# Description
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.
Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.
# User-Facing Changes
`help commands` and `scope commands` will now use `description` or
`extra_description`
`usage`-> `description`
`extra_usage` -> `extra_description`
Breaking change in the plugin protocol:
In the signature record communicated with the engine.
`usage`-> `description`
`extra_usage` -> `extra_description`
The same rename also takes place for the methods on
`SimplePluginCommand` and `PluginCommand`
# Tests + Formatting

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

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

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

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

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