# Description
This PR updates the `char` command to allow `Table` output due to the
`--list` parameter.
### Before
```nushell
char --list | transpose
Error: nu::parser::input_type_mismatch
× Command does not support string input.

Relative: #8248
After this pr, user can define const variable inside a module.
And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):
## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`
## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.
It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.
What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.
## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.
# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.
# Description
See also: #9743
Before:
`http <subcommand> -H` took a list in the form:
```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```
Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
Cookie: "acc=barfoo",
User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```
is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```
# User-Facing Changes
No breaking changes, but Records can now also be passed to `http
<subcommand> -H`.

# Description
Add `format duration` cmd to choose output unit.
This takes the previous `into duration --convert ...` behavior which
returned a string into its own `format duration` command.
This was suprising and not fitting with the general type signature for
the `into ...` commands.
This command for now lives in the `nu-cmd-extra` nursery.
# User-Facing Changes
## Breaking change
Removes formatting behavior from `into duration`
Now use `format duration` instead of `into duration --convert`
## Usage:
```
1sec | format duration us # Output data in microseconds
"2ms" | into duration | format duration sec # go from string to string
```
# Tests + Formatting
Basic example testing (including basic broadcast)
# Description
This deduplicates `ahash` as it was previously an outdated
build-dependency of `unicode-linebreak`
Should provide a small benefit to initial from scratch compile.

# Description

This command will always return a list, either because there are
multiple entries with the same frequency or just one.
It's implementation doesn't care about the composition of types as long
as they are number like, can be heterogeneous, will report
independently.
Work for #9812
Still support forming the median over homogeneous lists of `Duration` or
`Filesize`. Don't advertise `list<any>` as this can become funky when
given an even number of elements...
Work for #9812
# Description
Under the hood those are just `Value::partial_cmp` and this is defined
for all values and defines a partial order over `any`
Should address part of https://github.com/nushell/nushell/issues/9813
# User-Facing Changes
Reenable all behavior before `0.83`
# Tests + Formatting
Added an example to `math min` showing this cursedness
# Description
As the typechecker doesn't currently support having the same input type
but two different output types, collapse the `transpose` input/output
signatures for now so that we don't mistakenly think that when given a
`table` a `table is always returned.

# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of
```nushell
print "foo"
```
this PR enables the `any -> nothing` input / output type to allow this
again.
i've double checked and `print` is essentially the following snippet
```rust
if !args.is_empty() {
for arg in args {
arg.into_pipeline_data()
.print(engine_state, stack, no_newline, to_stderr)?;
}
} else if !input.is_nothing() {
input.print(engine_state, stack, no_newline, to_stderr)?;
}
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`
# User-Facing Changes
```nushell
"foo" | print
```
works again

# Description
Previously, we had a bug slip in about implied collection caused by
`$in`, that this output type would be of type `string`.
The type system fixes in 0.83 now make this more visible and cause
issues. This PR changes the output of the implied collection to `any`.
At some point in the future, we may want to carry the type through where
we can, but `any` should unblock using `$in`.

This PR fixes this not working `ansi --list | columns`. I originally
thought that this was a problem with `columns` but it turned out to be a
problem with the input output type of `ansi`. Since `ansi` was only
allowed to return strings, `columns` thought it was getting a string,
but it was a table.

# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.
Simplifies the example testing a bit.
# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.
# Description
The same procedure as for #9778 repeated for records.
# User-Facing Changes
Commands that directly supported applying their work directly to record
fields via cell paths, that worked before #9680 will now work again
# Tests + Formatting
Tried to limit the need to add new `.allow_variants_without_examples()`
by adjusting or adding tests to also use some records with access.

# Description
Reallow the commands that take cellpaths as rest parameters to operate
on table input data.
Went through all commands returned by
```
scope commands |
filter { |cmd| $cmd.signatures |
values |
any {|sig| $sig |
any {|$sig| $sig.parameter_type == rest and $sig.syntax_shape ==
cellpath }
}
} | get name
```
Only exception to that was `is-empty` that returns a bool.
# User-Facing Changes
Same table operations as in `0.82` should still be possible
Mitigates effects of #9680
# Description
If we reach the conclusion that the fields of a list are of `Type::Any`
there is no need to continue as the type will remain `Type::Any`
This should improve runtimes of `Value.get_type()` for lists with mixed
types.
# User-Facing Changes
None, a speedup in some cases.
# Tests + Formatting
Relies on existing tests
# Description
Those two commands did *not* vectorize over the input in the pure sense
as they performed a flat map. Now they return a list for each string
that gets split by them.
```
["foo" "bar"] | split chars
```

# Description
All commands that declared `.vectorizes_over_list(true)` now also
explicitly declare the list form of their scalar types.
- Explicit in/out list signatures for nu-command
- Explicit in/out list signatures for nu-cmd-extra
- Add comments about cellpath behavior that is still unresolved
# User-Facing Changes
Our type signatures will now be more explicit about which commands
support vectorization over lists.
On the downside this is a bit more verbose and less systematic.
# Description
Don't just use `List<Any>`, be precise for the vectorized form as well.
# User-Facing Changes
More explicit albeit verbose type information in the signature
should close https://github.com/nushell/nushell/issues/9774
# Description
given the help page of `into datetime`,
```
Parameters:
...rest <cellpath>: for a data structure input, convert data at the given cell paths
```
it looks like `into datetime` should accept tables as input 🤔
this PR
- adds the `table -> table` signature to `into datetime`
- adds a test to make sure the behaviour stays there

This PR is related to **Tests: clean up unnecessary use of cwd,
pipeline(), etc.
[#8670](https://github.com/nushell/nushell/issues/8670)**
- Removed the `r#"..."#` raw string literal syntax, which is unnecessary
when there are no special characters that need quoting from the tests
that use the `nu!` macro.
- `cwd:` and `pipeline()` has not changed
