# 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
}
)
}
# ...
```
# User-Facing Changes
- Add a `command_not_found` function to `$env.config.hooks`.

# Description
This adds two different features to `open`:
* The ability to pass more than one file to `open`.
* Support for using globs in the filenames
`open` will create a list stream and stream the output if there is more
than one file opened
Examples:
```
open file1.csv file2.csv file3.csv
```
```
open *.nu | where $it =~ "echo"
```
# User-Facing Changes
Multi-file and glob support in `open`. Original `open` functionality
should continue as before.

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
As title, closes: #7921closes: #8273
# User-Facing Changes
when define a closure without pipe, nushell will raise error for now:
```
❯ let x = {ss ss}
Error: nu::parser::closure_missing_pipe

╭─[entry #2:1:1]
1 │ let x = {ss ss}
· ───┬───
· ╰── Parsing as a closure, but || is missing
╰────
help: Try add || to the beginning of closure
```
`any`, `each`, `all`, `where` command accepts closure, it forces user
input closure like `{||`, or parse error will returned.
```

```
`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
written like `{||`, it's more likely a block but can capture variable
outside of scope:
```
❯ def test [input] { echo [0 1 2] | do { do { echo $input } } }; test aaa
aaa
```
Just realize that It's a big breaking change, we need to update config

# 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
When using `char`, I somehow missed the `--list` flag (even though it's
of course displayed in the help output). While it's maybe a bit
redundant to have a usage of the flag in the examples, I suspect that I
may not be alone in needing an extra nudge on getting that info 😄
# User-Facing Changes
Just an extra example in the `char` help output.
This PR adds a command `join` for performing SQL-style joins on Nushell
tables:
```
〉join -h
Join two tables
Usage:
> join {flags} <right-table> <left-on> (right-on)
Flags:
-h, --help - Display the help message for this command
-i, --inner - Inner join (default)
-l, --left - Left-outer join
-r, --right - Right-outer join
-o, --outer - Outer join
Signatures:
<table> | join list<any>, <string>, <string?> -> <table>
Parameters:
right-table <list<any>>: The right table in the join
left-on <string>: Name of column in input (left) table to join on
(optional) right-on <string>: Name of column in right table to join on. Defaults to same column as left table.
Examples:
Join two tables

# 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`.
https://github.com/nushell/nushell/pull/8379 removed the `-i` flag from
`get` and `select` because the new `?` functionality covers most of the
same use cases. However, https://github.com/nushell/nushell/issues/8480
made me realize that `-i` is still useful when dealing with cell paths
in variables.
This PR re-adds the `-i` flag to `get` and `select`. It works by just
marking every member in the cell path as optional, which will behave
_slightly_ differently than `-i` used to (previously it would suppress
any errors, even type errors) but IMO that's OK.
# Description
This PR adds a fix for reading tag values from YAML file.
A tag in YAML file is denoted by using the exclamation point ("!")
symbol.
For example - Key: !Value
Additional passing test has also been added supporting the bug fix -
- `test_convert_yaml_value_to_nu_value_for_tagged_values`
The fix passes all the below required tests suites locally -
>To check standard code formatting.
- `cargo fmt --all -- --check` (`cargo fmt --all` applies these changes)
>To check that you're using the standard code style.
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A

This is a follow up from https://github.com/nushell/nushell/pull/7540.
Please provide feedback if you have the time!
## 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
```
### List Examples
```
〉[{foo: 1} {foo: 2} {}].foo
Error: nu:🐚:column_not_found
× Cannot find column
╭─[entry #30:1:1]

╭───┬─────╮
│ # │ foo │

╰───┴─────╯
```
# 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.

Prior to this PR, `ls` would return `nothing` in an empty directory.
After this PR, it returns an empty `List`. This makes the behaviour of
`ls` more consistent and easier to reason about (IMO).
This was prompted by a user noticing that `ls | where size == 0KB and
type == file` breaks when run in an empty directory:
```
× Input type not supported.
╭─[entry #12:1:1]

```
If people agree with this change, let's wait until after the 0.77
release so we have a bit more time to test it.

# 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.

This reverts https://github.com/nushell/nushell/pull/8114 which upgraded
to `notify` (a file watching crate used by the `watch` command) v5.
`notify` v5 has several breaking changes and it's much harder to use. It
no longer includes debouncing of file system events, which I think is
essential functionality for `watch`. @WindSoilder was going to try
writing our own debouncing functionality but I don't think he had time
to finish it.
@WindSoilder Is it OK if we revert this for the 0.77 release (March 14)?
We can try again for 0.78

# Description
Fix for data ambiguity noted in #8244.
Basic change is to use nanosecond resolution for unix timestamps (stored
in type Int). Previously, a timestamp might have seconds, milliseconds
or nanoseconds, but it turned out there were overlaps in data ranges
between different resolutions, so there wasn't always a unique mapping
back to date/time.
Due to higher precision, the *range* of dates that timestamps can map to
is restricted. Unix timestamps with seconds resolution and 64 bit
storage can cover all dates from the Big Bang to eternity. Timestamps
with seconds resolution and 32 bit storage can only represent dates from
1901-12-13 through 2038-01-19. The nanoseconds resolution and 64 bit
storage used with this fix can represent dates from 1677-09-21T00:12:44
to 2262-04-11T23:47:16, something of a compromise.
# User-Facing Changes
_(List of all changes that impact the user experience here. This helps

## `<datetime> | into int`
Converts to nanosecond resolution
```rust
〉date now | into int
1678084730502126846
```
This is the number of non-leap nanoseconds after the unix epoch date:
1970-01-01T00:00:00+00:00.
Conversion fails for dates outside the supported range:
```rust
〉1492-10-12 | into int
Error: nu:🐚:incorrect_value
× Incorrect value.
╭─[entry #51:1:1]

╰────
```
## `<int> | into datetime`
Can no longer fail or produce incorrect results for any 64-bit input:
```rust
〉0 | into datetime
Thu, 01 Jan 1970 00:00:00 +0000 (53 years ago)
〉"7fffffffffffffff" | into int -r 16 | into datetime
Fri, 11 Apr 2262 23:47:16 +0000 (in 239 years)
〉("7fffffffffffffff" | into int -r 16) * -1 | into datetime
Tue, 21 Sep 1677 00:12:43 +0000 (345 years ago)
```
## `<date> | date to-record` and `<date> | date to-table`
Now both have a `nanosecond` field.
```rust
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-record
╭────────────┬───────────╮

```
This change was not mandated by the OP problem, but it is nice to be
able to see the nanosecond bits that were present in Nushell `date` type
all along.

Fixes#8341.
The `CustomValue::to_json()` function is an odd duck; it defaults to
returning `null`, and no `CustomValue` implementations override it to do
anything useful. I forgot to implement `to_json()` for `SQLiteDatabase`,
so `open foo.db | to json` was returning `null`.
To fix this, I've removed `CustomValue::to_json()` and now `to json`
will collect a `CustomValue` into a regular `Value` before doing a JSON
conversion.

# 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.

# Description
_(Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.)_
This pull request removes `Reqwest` and replaces it with `Ureq` to
remove some of our dependencies, giving us faster compile times as well
as smaller binaries. `Ureq` does not have an async runtime included so
we do not need build heavy dependencies such as `Tokio`. From older
tests I had the number of build units be reduced from `430 -> 392`.
The default of `Ureq` uses `Rustls` but it has been configured to
instead use `native_tls` which should work exactly the same as the `tls`
works now.
I removed `content-length` from the http commands as after refactoring i
did not see a reason to have it available, correct me if this is
something we should preserve.
In the medium, to long term, we should maybe consider changing to
`rustls` to have the same `tls` on all platforms.

# 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).
Fixes https://github.com/nushell/nushell/issues/7648,
https://github.com/nushell/nushell/issues/8026,
https://github.com/nushell/nushell/issues/7512,
https://github.com/nushell/nushell/issues/5780,
https://github.com/nushell/nushell/issues/7754
No effect: https://github.com/nushell/nushell/issues/8122 (we might
revisit the completions code after this PR)
Should use custom command instead:
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

### What?
This change removes 3 flags (`--all`, `--both`, and `--format`) from
`str trim`. This is a net reduction of ~450 LoC and `str trim` no longer
depends on `fancy_regex`.
### Why?
I found these flags to be quite confusing when reviewing `str trim`
earlier today:
1. `--all` removes characters even if they're in the centre of the the
string.
- This is arguably not "trimming"! In all programming languages I'm
familiar with, trimming only affects the start and end of a string.
- If someone needs to do this, `str replace` is more natural IMO
2. `--both` trims from the left and right
- Confusing and unnecessary given that this is also the default
behaviour
3. `--format` replaces multiple spaces with a single space, even in the
centre of the string
- Again, I don't think this falls under the scope of "trimming". IMO
`str replace` is a more natural fit
I believe that `str trim` is simpler and easier to understand after this
change.
### Before
```
〉help str trim
Trim whitespace or specific character
Search terms: whitespace, strip, lstrip, rstrip
Usage:
> str trim {flags} ...(rest)
Flags:
-h, --help - Display the help message for this command
-c, --char <String> - character to trim (default: whitespace)
-l, --left - trims characters only from the beginning of the string
-r, --right - trims characters only from the end of the string
-a, --all - trims all characters from both sides of the string *and* in the middle
-b, --both - trims all characters from left and right side of the string
-f, --format - trims spaces replacing multiple characters with singles in the middle
```
### After
```
〉help str trim
Trim whitespace or specific character
Search terms: whitespace, strip, lstrip, rstrip
Usage:
> str trim {flags} ...(rest)
Flags:
-h, --help - Display the help message for this command
-c, --char <String> - character to trim (default: whitespace)
-l, --left - trims characters only from the beginning of the string
-r, --right - trims characters only from the end of the string

# 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

- `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.
