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
> [{a: 1 b: 2}] | join [{a: 1 c: 3}] a

# 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`.
# Description
This PR tweaks the enable_vt_processing() function with more verbose
error handling. This is related to #8344.

it outputs the command being run. New line characters are included.
This allows for:

· nushell/nushell](https://github.com/nushell/nushell/issues/6264)
- The possibility of *Atuin* to work work *Nushell*. *Atuin* hooks need
to know the current repl input before it is run.

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
Was original asked here:
https://github.com/nushell/nushell/pull/8405#issuecomment-1465062652
Make it easier to extend standard library with submodules.
(For a new submodule called `xx.nu` the tests can be written in
`test_xx.nu`).
Test discovery is implemented.

# Description
Fixes the issue where there is no way to escape `FOO=BAR` in a way that
treats it as a file path/executable name. Previously `^FOO=BAR` would be
handled as an environment shorthand. Now, environment shorthands are not
allowed to start with `^`. To create an environment shorthand value that
uses `^` as the first character of the environment variable name, use
quotes, eg `"^FOO"=BAR`
# User-Facing Changes
This should enable `=` being in paths and external command names in
command position.

Bumps [mockito](https://github.com/lipanski/mockito) from 0.32.5 to
1.0.0.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/lipanski/mockito/releases">mockito's
releases</a>.</em></p>
<blockquote>
<h2>1.0.0</h2>
<p>🎈 7 years and 63 releases later, it's finally time for the
1.0 🎈</p>
<h2>Changes</h2>
<ul>
<li><strong>[Breaking]</strong> The legacy interface was removed in this
version</li>
<li><strong>[Breaking]</strong> <code>Mock::with_body_from_fn</code> was
renamed to <code>Mock::with_chunked_body</code> - the former is still
supported with a deprecation warning</li>
<li>Mocks are only cleared when the server is dropped, not when the mock
is dropped - this means you <strong>don't have to assign mocks to
variables any more</strong> (unless you want to call other methods on
them)</li>
<li>Introduced the <code>Mock::remove</code> and
<code>Mock::remove_async</code> methods to remove mocks on demand</li>
</ul>
<h2>Major changes since 0.31</h2>
<ul>
<li>Tests can now run in parallel</li>
<li>Support for HTTP2</li>
<li>An async interface for all actions (though the sync interface is
also available)</li>
<li>Mock multiple server/hosts at the same time</li>
</ul>
<p>For a list of all the changes please check the <a
href="https://github.com/lipanski/mockito/releases">release log</a>.</p>
<h2>Migrating to the new API</h2>
<p>Legacy API:</p>
<pre lang="rust"><code>let m1 = mockito::mock("GET",
"/hello").with_body("hello").create();
let m2 = mockito::mock("GET",
"/bye").with_body("bye").create();
<p>// Use one of these to configure your client
let host = mockito:server_address();
let url = mockito::server_url();
</code></pre></p>
<p>New API:</p>
<pre lang="rust"><code>let mut server = mockito::Server::new();
server.mock("GET",
"/hello").with_body("hello").create();
server.mock("GET",
"/bye").with_body("bye").create();
<p>// Use one of these to configure your client
let host = server.host_with_port();
let url = server.url();
</code></pre></p>
<blockquote>
<p>If you can't migrate to the new API in one go, consider using version
0.32.5, which supports both the legacy API as well as the new API.</p>
</blockquote>
<h2>Migrating to the async API</h2>
<p>In order to write async tests, you'll need to use the
<code>_async</code> methods:</p>

# Description
Fixes: #8402#8391
The cause of these issue if when we want to evaluate a expression with
`Value::Error`, nushell show error immediately. To fix the issue, we can
wrap the `Value::Error` into a `Value::Record`. So user can see the
message he want.
# User-Facing Changes
Before
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
Error: nu:🐚:division_by_zero
× Division by zero.
╭─[entry #2:1:1]
1 │ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
· ┬
· ╰── division by zero
╰────
```
After
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
error is {msg: Division by zero., debug: DivisionByZero { span: Span { start: 43104, end: 43105 } }, raw: DivisionByZero { sp
an: Span { start: 43104, end: 43105 } }}
```
As we can see, error becomes a record with `msg`, `debug`, `raw`
columns.
1. msg column is a user friendly message.
2. debug column is more about `Value::Error` information as a string.
3. raw column is a `Value::Error` itself, if user want to re-raise the
error, just use `$e | get raw`

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]
1 │ [{foo: 1} {foo: 2} {}].foo
· ─┬ ─┬─
· │ ╰── cannot find column 'foo'
· ╰── value originates here

╭───┬─────╮
│ # │ 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.
Should close#8444.
# Description
as asked by @presidento, i've used a generic command to run the tests.
i've also transformed the "a concrete example" sections into quote
blocks to make them stand out less.
not sure about that one, please tell me what you think 😋
i think a small example is always helpfull, maybe some work has to be
done to make it better 💪

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]
1 │ ls | where size == 0KB and type == file
· ─┬ ──┬──
· │ ╰── only list, binary, raw data or range input data is supported
· ╰── input type: nothing
╰────
```
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
The correction made here concerns the issue #8431. Indeed, the algorithm
initially proposed to remove elements of a `vector` performed a loop
with `remove` and an incident therefore appeared when several values
were equal because the deletion was done outside the length of the
vector:
```rust
let mut found = false;
for (i, col) in cols.clone().iter().enumerate() {
if col == col_name {
cols.remove(i);
vals.remove(i);
found = true;
}
}
```
Then, `[[a, a]; [1, 2]] | reject a: ` gave `thread 'main' panicked at
'removal index (is 1) should be < len (is 1)',
crates/nu-protocol/src/value/mod.rs:1213:54`.
The proposed correction is therefore the implementation of the
`retain_mut` utility dedicated to this functionality.
```rust
let mut found = false;
let mut index = 0;
cols.retain_mut(|col| {
if col == col_name {
found = true;
vals.remove(index);
false
} else {
index += 1;
true
}
});
```

# Description
Prevents alias from aliasing itself. It allows a commonly requested
pattern similar to `alias ls = ls -l`.
One small issue is that the syntax highlighting is a bit off:

# 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.

# Tests + Formatting
Haven't even looked at stdlib `tests.nu` yet.
Other todos:
* address module todos.
* integrate into std lib, rather than as standalone module. Somehow
arrange for `use .../standard_library/std.nu` to load this module
without having to put all the source in `std.nu`?
* Maybe command should be `std dirs ...`?
* what else do `enter` and `exit` do that this should do? Then deprecate
those commands.

# Description
This works around a bug introduced by #8058
We should revisit the original fix, as it makes some assumptions about
how stdout redirection is used by `table`. We use the stdout by default
for table regularly during a repl session, so we should instead
special-case case for handling externals.
# User-Facing Changes
Restores the original default `table` behaviour for binary data

This is a follow-up from https://github.com/nushell/nushell/pull/8173,
which was merged shortly after the 0.76 release. That PR changed
`default_env.nu` so that the user's home folder is displayed as `~` in
the left prompt. It did so using `get -i`.
This PR just rewrites the Nu code from
https://github.com/nushell/nushell/pull/8173 to use `try`/`catch`
instead of `-i`, which will make it easier to remove the `-i` flags from
`get` and `select` eventually (see
https://github.com/nushell/nushell/pull/8379).
I would like to merge this before the 0.77 release, so we don't end up
with lots of `env.nu` files using `get -i` out in the wild.
A tiny fix: make the naming of the `sqlite` feature consistent across
both `Cargo.toml` and the `version` command's output. Previously
`version` displayed it as `database`, a user was asking about that the
other day.
# 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
```

Fixes#8245. Instead of trying to use `nano` or `notepad` as defaults,
it errors out if finds that `buffer_editor` , $EDITOR, $VISUAL do not
exist.
If the PR is landed, Ill update the website as it means what its in
there is no longer correct.

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
