Rename misused "deprecation" to removal (#10000)
# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".

But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.

# User-Facing Changes
Command category changed from `deprecated` to `removed`

test: clear parent envs to prevent leakage to tests (#9976)
Running tests locally from nushell with customizations (i.e.
$env.PROMPT_COMMAND etc) may lead to failing tests as that customization
leaks to the sandboxed nu itself.

Remove `FILE_PWD` from env

Rename main to script name when running scripts (#9948)
# Description

This PR does three related changes:

* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.

Combined, the above allow the user to see the script name in the help
output of scripts, like so:


![image](https://github.com/nushell/nushell/assets/547158/741d192c-0a39-45a7-8f36-3a0dc8eeae2b)

NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.

# User-Facing Changes

One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

Fix duration type to not report months or years (#9632)
<!--

you can also mention related issues, PRs or discussions!
-->
This PR should close #8036, #9028 (in the negative) and #9118.

Fix for #9118 is a bit pedantic.  As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec
```
with this PR, you now get:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".

# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).

# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.

## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.

Scripts that depended on month or year time units on output will need to
be changed.

### Examples
```
> 365day
52wk 1day
## Used to be: 
## 1yr

> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day  │ 1  │
│ sign │ +  │
╰──────┴────╯

## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week        │ 56 │
│ day         │ 6  │
│ hour        │ 6  │
│ minute      │ 7  │
│ second      │ 8  │
│ millisecond │ 9  │
│ microsecond │ 10 │
│ nanosecond  │ 11 │
│ sign        │ +  │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.

Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

Auto-expand table based on terminal width (#9934)
# Description

This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.

This sets the default config value in both the Rust and the default
nushell config.

To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.

Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

Make Value::columns return slice instead of cloned Vec (#9927)
# Description
This PR changes `Value::columns` to return a slice of columns instead of
cloning said columns. If the caller needs an owned copy, they can use
`slice::to_vec` or the like. This eliminates unnecessary Vec clones
(e.g., in `update cells`).

Nothing return type (#9935)
# Description
Fix #9928. When parsing input/output types `nothing` was incorrectly
coerced to `any`. This is addressed by changing how
[to_type](0ad1ad4277/crates/nu-protocol/src/syntax_shape.rs (L121))
method handles `nothing` syntax shape. Also `range` syntax shape is
addressed the same way.

# User-Facing Changes
`nothing` and `range` are correctly displayed in help and strictly
processed by type checking. This will break definitions that were not in
fact output nothing or range and incorrect uses of functions which input
nothing or range.

Examples of correctly defined functions:

Add an option to set header on border (style) (#9920)
fix #9796

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.

Relative: #8248 

After this pr, user can define const variable inside a module.

![image](https://github.com/nushell/nushell/assets/22256154/e3e03e56-c4b5-4144-a944-d1b20bec1cbd)

And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):

![image](https://github.com/nushell/nushell/assets/22256154/b2c14760-3f27-41cc-af77-af70a4367f2a)

## 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.

Replace &Span with Span since Span is Copy (#9770)
# 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`.

Remove Signature.vectorizes_over_list entirely (#9777)
# 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.

`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.

sync default config / env with default behaviour without any configuration (#9676)
related PRs and issues
- supersedes https://github.com/nushell/nushell/pull/9633
- should close https://github.com/nushell/nushell/issues/9630

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.

## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`

## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011

# User-Facing Changes
this should not change anything, just make sure the default behaviour of
Nushell and the `default_config.nu` are in sync.

Clean up tests containing unnecessary cwd: tokens (#9692)
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).

add match guards (#9621)
## description

this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
   _ if $x starts-with 'nu' => {},
   $x => {}
}
```

these work pretty much like rust's match guards, with few limitations:

1. multiple matches using the `|` are not (yet?) supported
 
```nushell
match $num {
    0 | _ if (is-odd $num) => {},
    _ => {}
}
```

2. blocks cannot be used as guards, (yet?)

```nushell
match $num {
    $x if { $x ** $x == inf } => {},
     _ => {}
}
```

## checklist
- [x] syntax
- [x] syntax highlighting[^1]
- [x] semantics
- [x] tests
- [x] clean up

Input output checking (#9680)
# Description

This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.

This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This work enforces many more checks on pipeline type correctness than
previous nushell versions. This strictness may uncover incompatibilities
in existing scripts or shortcomings in the type information for internal
commands.

Remove broken compile-time overload system (#9677)
# Description

This PR removes the compile-time overload system. Unfortunately, this
system never worked correctly because in a gradual type system where
types can be `Any`, you don't have enough information to correctly
resolve function calls with overloads. These resolutions must be done at
runtime, if they're supported.

That said, there's a bit of work that needs to go into resolving
input/output types (here overloads do not execute separate commands, but
the same command and each overload explains how each output type
corresponds to input types).

This PR also removes the type scope, which would give incorrect answers
in cases where multiple subexpressions were used in a pipeline.

# User-Facing Changes

Finishes removing compile-time overloads. These were only used in a few
places in the code base, but it's possible it may impact user code. I'll
mark this as breaking change so we can review.

```nushell
{ name: 'Him', age: 12 } 

# ,

{ age: 100, name: 'It' }

# and

{ name: 'Red', age: 69, height: "5-8" }

# will all match

record<name: string, age: int>

# previously only the first one would match
```

however, something like

```nushell

Exclude deprecated commands from completions (#9612)
# Description
We previously simply searched all commands in the working set. As our
deprecated/removed subcommands are documented by stub commands that
don't do anything apart from providing a message, they were still
included.
With this change we check the `Signature.category` to not be
`Category::Deprecated`.

## Note on performance
Making this change will exercise `Command.signature()` more
frequently! As the rust-implemented commands include their builders here
this probably will cause a number of extra allocations. There is
actually no valid reason why the commands should construct a new
`Signature` for each call to `Command.signature()`.
This will introduce some overhead to generate the completions for
commands.

remove let-env, focus on mutating $env (#9574)
# Description

For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.

So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.

Before:

```
let-env FOO = "BAR"
```

Now:

```
$env.FOO = "BAR"
```

It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

Improve type hovers (#9515)
# Description

This PR does a few things to help improve type hovers and, in the
process, fixes a few outstanding issues in the type system. Here's a
list of the changes:

* `for` now will try to infer the type of the iteration variable based
on the expression it's given. This fixes things like `for x in [1, 2, 3]
{ }` where `x` now properly gets the int type.
* Removed old input/output type fields from the signature, focuses on
the vec of signatures. Updated a bunch of dataframe commands that hadn't
moved over. This helps tie things together a bit better
* Fixed inference of types from subexpressions to use the last
expression in the block
* Fixed handling of explicit types in `let` and `mut` calls, so we now
respect that as the authoritative type

I also tried to add `def` input/output type inference, but unfortunately
we only know the predecl types universally, which means we won't have
enough information to properly know what the types of the custom
commands are.

# User-Facing Changes

Script typechecking will get tighter in some cases
Hovers should be more accurate in some cases that previously resorted to
any.

Skip strum in regular nu-protocol build (#9445)
# Description
`derive(EnumIter)` is only required to run completeness tests.
Thus make the derive conditional on test and move `strum` and
`strum_macros` to the dev dependencies.

## Is it worth it?

Removing this derive does not change the binary size (checked via `cargo
bloat --crates` from `cargo-bloat`).
Compile time change is below a second so hard to judge based on a single
run of `cargo clean --profile dev; cargo build --timings`
Unsure if this negatively impacts how incremental compilation can
recompile when you switch between `cargo build`/`run` and `cargo test`
in your local workflow.

To get rid of `strum`/`strum_macros` as a proc macro crate we would need
to also remove it from `reedline`.
Further more a crate in the `polars` dependency tree uses `strum`
(curently not as relevant for the 1.0 build).
