# Description
issue #8167
Remove the `(link)` to the docs for `ShellError` and `ParseError`. As
per discussion on the issue, the nu-parser version didn't update on the
docs causing deadlinks for those errors, which brought the usefullness
of these links into question and it was decided to remove all of them
that `derive(diagnostic)`.

# Description
Previously `nix run nixpkgs#hello` was lexed as `Item, Item, Item,
Comment`, however, `#hello` is *not* supposed to be a comment here and
should be parsed as part of the third `Item`.
This change introduces this behavior by not interrupting the parse of
the current token upon seeing a `#`.
Thank you so much for considering this, I think many `nix` users will be
grateful for this change and I think this will lead to more adaptation
in the ecosystem.
- closes#8137 and #6335
# User-Facing Changes
- code like `somecode# bla` and `somecode#bla` will not be parsed as
`somecode, comment` but as `somecode#bla`, hence this is a breaking
change for all users who didn't put a space before a comment introducing
token (`#`)

This does two fixes for bare words:
* It changes completions for paths to wrap a path with backticks if it
starts with a number. This helps bare words that start with numbers be
separate from unit values
* It allows bare words wrapped with backticks to be the name of a
command. Backtick values in command positions are no longer treated as
strings

# Description
Added a few syntax errors in ints and strings, changed parser to stop
and show that error rather than continue trying to parse those tokens as
some other shape. However, I don't see how to push this direction much
further, and most of the classic confusing errors can't be changed.
Flagged as WIP for the moment, but passes all checks and works better
than current release:
1. I have yet to figure out how to make these errors refer back to the
book, as I see some other errors do.
2. How to give syntax error when malformed int is first token in line?
Currently parsed as external command, user gets confusing error message.
3. Would like to be more strict with *decimal* int literals (lacking,
e.g, `0x' prefix). Need to tinker more with the order of parse shape
calls, currently, float is tried after int, so '1.4' has to be passed.
_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_

A *correct* number in first token would be evaluated, but an *incorrect*
one is treated as external command? Confusing to users.
```bash
〉0 + 0x22bogus
Error:
× Invalid syntax
╭─[entry #5:1:1]
1 │ 0 + 0x22bogus
· ────┬────
· ╰── Syntax error in int, invalid digits in radix 16 int.
╰────
```
Can give syntax error if token is unambiguously int literal. e.g has 0b
or 0x prefix, could not be a float.
```bash
〉0 + 098bogus
Error: nu::parser::unsupported_operation (link)
× Types mismatched for operation.
╭─[entry #6:1:1]

· │ │ ╰── string
· │ ╰── doesn't support these values.
· ╰── int
╰────
help: Change int or string to be the right types and try again.
```
But *decimal* literal (no prefix) can't be too strict. Parser is going
to try float later. So '1.4' must be passed.
# User-Facing Changes
First and foremost, more specific error messages for typos in string and
int literals. Probably improves interactive user experience.
But a script that was causing and then checking for specific error might
notice a different error message.

# Description
As title, we can't provide examples for plugin commands, this pr would
make it possible
# User-Facing Changes
Take plugin `nu-example-1` as example:
```
❯ nu-example-1 -h
PluginSignature test 1 for plugin. Returns Value::Nothing
Usage:
> nu-example-1 {flags} <a> <b> (opt) ...(rest)
Flags:
-h, --help - Display the help message for this command
-f, --flag - a flag for the signature
-n, --named <String> - named string
Parameters:
a <int>: required integer value
b <string>: required string value
(optional) opt <int>: Optional number
...rest <string>: rest value string
Examples:
running example with an int value and string value
> nu-example-1 3 bb
```
The examples session is newly added.
## Basic idea behind these changes
when nushell query plugin signatures, plugin just returns it's signature
without any examples, so nushell have no idea about the examples of
plugin commands.
To adding the feature, we just making plugin returns it's signature with
examples.
Before:
```
1. get signature
---------------->
Nushell ------------------ Plugin
<-----------------
2. returns Vec<Signature>
```
After:
```
1. get signature
---------------->
Nushell ------------------ Plugin
<-----------------
2. returns Vec<PluginSignature>
```
When writing plugin signature to $nu.plugin-path:
Serialize `<PluginSignature>` rather than `<Signature>`, which would
enable us to serialize examples to `$nu.plugin-path`
## Shortcoming
It's a breaking changes because `Plugin::signature` is changed, and it
requires plugin authors to change their code for new signatures.
Fortunally it should be easy to change, for rust based plugin, we just
need to make a global replace from word `Signature` to word
`PluginSignature` in their plugin project.
Our content of plugin-path is really large, if one plugin have many
examples, it'd results to larger body of $nu.plugin-path, which is not
really scale. A solution would be save register information in other
binary formats rather than `json`. But I think it'd be another story.

# Description
Support extended unicode escapes in strings with same syntax as Rust:
`"\u{6e}"`.
# User-Facing Changes
New syntax in string literals, `\u{NNNNNN}`, to go along with the
existing `\uNNNN`.
New syntax accepts 1-6 hex digits and rejects values greater than
0x10FFFF (max Unicode char)..
_(List of all changes that impact the user experience here. This helps

Won't break existing scripts, since this is new syntax.
We might consider deprecating `char -u`, since users can now embed
unicode chars > 0xFFFF with the new escape.

This adds the `SyntaxShape::Decimal` so you can create custom commands
with `decimal` types such as:
```shell
def cmd [x:decimal] { echo $x }
```
/cc @kurokirasama
Internally this is a little messy since we have `Type::Float` and
`SyntaxShape::Decimal`. I originally named it `float` and
`SyntaxShape::Float` but since we have `into decimal` and `1.1 |
describe` reports `decimal`, I decided to change the SyntaxShape.

# Description
This PR makes changes that allow underscores in numbers.
Example:
```nu
# allows underscores to be placed arbitrarily to enhance readability.
let pi = 3.1415_9265_3589_793
# works with integers
let num = 1_000_000_000_000
let fav_color = 0x68_9d_6a
```
I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give
better error messages. Similarly for `assert!(a != b)` and
`assert_ne!(a, b)`. Basically all instances were comparing primitives
(string slices or integers), so there is no loss of generality from
special-case macros,
I have also fixed a number of typos in comments, variable names, and a
few user-facing messages.
Add recursion limit to `def` and `block`.
Summary of this PR , it will detect if `def` call itself or not .
Then execute by using `stack` which I think best choice to use with this
design and core as it is available in all crates and mutable and
calculate the recursion limit on calling `def`.
Set 50 as recursion limit on `Config`.
Add some tests too .

# Description
Purely for consistency, various remaining instances of `$nothing`
(almost all of which were in test code) have been changed to `null`.
Now, the only place that refers to `$nothing` is the parser code which
implements it.
# User-Facing Changes
The default config.nu now uses `null` in certain places where it used
`$nothing`.

Reverts nushell/nushell#7448
Some surprising behavior in how we do this. For example:
```
〉if (true || false) { print "yes!" } else { print "no!" }
no!
〉if (true or false) { print "yes!" } else { print "no!" }
yes!
```
This means for folks who are using the old `||`, they possibly get the
wrong answer once they upgrade. I don't think we can ship with that as
it will catch too many people by surprise and just make it easier to
write buggy code.
# Description
We got some feedback from folks used to other shells that `try/catch`
isn't quite as convenient as things like `||`. This PR adds `&&` as a
synonym for `;` and `||` as equivalent to what `try/catch` would do.
# User-Facing Changes

# Description
This PR moves the `where` command to a parser keyword. While it still
uses the shape-directed parsing dictated by the signature, we're free to
change the parsing code now to a custom one once we remove the syntax
shapes.
As a side effect, the `where -b` flag was removed and its functionality
has moved to the new `filter` command.
Just FYI, other commands that take row conditions:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`
We can either move these to the parser as well or make them accept a
closure instead of row condition.

New `filter` command which replaces `where -b` functionality.

# Description
fixes#7384
This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

`else` block will no longer capture variables as it will now use a block
instead of a closure.

# Description
Closes#7110. ~~Note that unlike "real" `mut` vars, $env can be deeply
mutated via stuff like `$env.PYTHON_IO_ENCODING = utf8` or
`$env.config.history.max_size = 2000`. So, it's a slightly awkward
special case, arguably justifiable because of what $env represents (the
environment variables of your system, which is essentially "outside"
normal Nushell regulations).~~
EDIT: Now allows all `mut` vars to be deeply mutated using `=`, on
request.

We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.
Operator precedence
`and` > `xor` > `or`
Added logic and precedence tests.
# Description
This PR is a response to the issues raised in
https://github.com/nushell/nushell/pull/7087. It consists of two
changes:
* `export-env`, when evaluated in `overlay use`, will see the original
environment. Previously, it would see the environment from previous
overlay activation.
* Added a new `--reload` flag that reloads the overlay. Custom
definitions will be kept but the original definitions and environment
will be reloaded.
This enables a pattern when an overlay is supposed to shadow an existing
environment variable, such as `PROMPT_COMMAND`, but `overlay use` would
keep loading the value from the first activation. You can easily test it
by defining a module
```
module prompt {
export-env {
let-env PROMPT_COMMAND = (date now | into string)
}
}
```
Calling `overlay use prompt` for the first time changes the prompt to
the current time, however, subsequent calls of `overlay use` won't
change the time. That's because overlays, once activated, store their
state so they can be hidden and restored at later time. To force-reload
the environment, use the new flag: Calling `overlay use --reload prompt`
repeatedly now updates the prompt with the current time each time.
# User-Facing Changes
* When calling `overlay use`, if the module has an `export-env` block,
the block will see the environment as it is _before_ the overlay is
activated. Previously, it was _after_.
* A new `overlay use --reload` flag.

# Description
As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.
And if the command is executed directly like: `cat tmp`, the result
won't change.
Fixes: #6816Fixes: #3980
Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.
If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.
Mutable variables allow mutation via the assignment operator (=).
❯ mut x = 100
❯ $x = 200
❯ print $x
200
Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:
❯ mut x = 123; {|| $x }

The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.
Mutation can occur with fields as well, as in this case:
❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y
On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.
Disable backtrace on miette
- gimli crate requires several seconds
Disable diagnostics on wax
- depends on an outdated miette version
Builds fine, no observable loss in diagnostics quality of life
Removes 10 crates that have to be compiled.
* Remove unnecessary `#[allow]` annots
Reduce the number of lint exceptions that are not necessary with the
current state of the code (or more recent toolchain)
* Remove dead code from `FileStructure` in nu-command
* Replace `allow(unused)` with relevant feature switch
* Deal with `needless_collect` with annotations
* Change hack for needless_collect in `from json`
This change obviates the need for `allow(needless_collect)`
Removes a pessimistic allocation for empty strings, but increases
allocation size to `Value`
Probably not really worth it.
* Revert "Deal with `needless_collect` with annotations"
This reverts commit 05aca98445.
The previous state seems to better from a performance perspective as a
`Vec<String>` is lighter weight than `Vec<Value>`
