Remove lazy records (#12682)
# Description
Removes lazy records from the language, following from the reasons
outlined in #12622. Namely, this should make semantics more clear and
will eliminate concerns regarding maintainability.

# User-Facing Changes
- Breaking change: `lazy make` is removed.
- Breaking change: `describe --collect-lazyrecords` flag is removed.
- `sys` and `debug info` now return regular records.

# After Submitting
- Update nushell book if necessary.
- Explore new `sys` and `debug info` APIs to prevent them from taking
too long (e.g., subcommands or taking an optional column/cell-path
argument).

add raw-string literal support (#9956)
# Description

This PR adds raw string support by using `r#` at the beginning of single
quoted strings and `#` at the end.

Notice that escapes do not process, even within single quotes,
parentheses don't mean anything, $variables don't mean anything. It's
just a string.
```nushell
❯ echo r#'one\ntwo (blah) ($var)'#
one\ntwo (blah) ($var)
```
Notice how they work without `echo` or `print` and how they work without
carriage returns.
```nushell
❯ r#'adsfa'#
adsfa
❯ r##"asdfa'@qpejq'##
asdfa'@qpejq
❯ r#'asdfasdfasf
∙ foqwejfqo@'23rfjqf'#
```
They also have a special configurable color in the repl. (use single
quotes though)

![image](https://github.com/nushell/nushell/assets/343840/8780e21d-de4c-45b3-9880-2425f5fe10ef)

They should work like rust raw literals and allow `r##`, `r###`,
`r####`, etc, to help with having one or many `#`'s in the middle of
your raw-string.

They should work with `let` as well.

```nushell
r#'some\nraw\nstring'# | str upcase
```

Make exit code available in catch block (#12648)
# Description
Bandaid fix for #12643, where it is not possible to get the exit code of
a failed external command while also having the external command inherit
nushell's stdout and stderr. This changes `try` so that the exit code of
external command is available in the `catch` block via the usual
`$env.LAST_EXIT_CODE`.

# Tests + Formatting
Added one test.

# After Submitting
Rework I/O redirection and possibly exit codes.

Msgpack commands (#12664)
# Description

I thought about bringing `nu_plugin_msgpack` in, but that is MPL with a
clause that prevents other licenses, so rather than adapt that code I
decided to take a crack at just doing it straight from `rmp` to `Value`
without any `rmpv` in the middle. It seems like it's probably faster,
though I can't say for sure how much with the plugin overhead.

@IanManske I started on a `Read` implementation for `RawStream` but just
specialized to `from msgpack` here, but I'm thinking after release maybe
we can polish it up and make it a real one. It works!

# User-Facing Changes
New commands:

- `from msgpack`
- `from msgpackz`
- `to msgpack`
- `to msgpackz`

# Tests + Formatting
Pretty thorough tests added for the format deserialization, with a
roundtrip for serialization. Some example tests too for both `from
msgpack` and `to msgpack`.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Deprecate register and add plugin use (#12607)
# Description

Adds a new keyword, `plugin use`. Unlike `register`, this merely loads
the signatures from the plugin cache file. The file is configurable with
the `--plugin-config` option either to `nu` or to `plugin use` itself,
just like the other `plugin` family of commands. At the REPL, one might
do this to replace `register`:

```nushell
> plugin add ~/.cargo/bin/nu_plugin_foo
> plugin use foo
```

This will not work in a script, because `plugin use` is a keyword and
`plugin add` does not evaluate at parse time (intentionally). This means
we no longer run random binaries during parse.

The `--plugins` option has been added to allow running `nu` with certain
plugins in one step. This is used especially for the `nu_with_plugins!`
test macro, but I'd imagine is generally useful. The only weird quirk is
that it has to be a list, and we don't really do this for any of our
other CLI args at the moment.

`register` now prints a deprecation parse warning.

This should fix #11923, as we now have a complete alternative to
`register`.

# User-Facing Changes

- Add `plugin use` command
- Deprecate `register`
- Add `--plugins` option to `nu` to replace a common use of `register`

# Tests + Formatting

I think I've tested it thoroughly enough and every existing test passes.
Testing nu CLI options and alternate config files is a little hairy and
I wish there were some more generic helpers for this, so this will go on
my TODO list for refactoring.

- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Make the same file error more likely to appear (#12601)
# Description
When saving to a file we currently try to check if the data source in
the pipeline metadata is the same as the file we are saving to. If so,
we create an error, since reading and writing to a file at the same time
is currently not supported/handled gracefully. However, there are still
a few instances where this error is not properly triggered, and so this
PR attempts to reduce these cases. Inspired by #12599.

# Tests + Formatting
Added a few tests.

# After Submitting
Some commands still do not properly preserve metadata (e.g., `str trim`)
and so prevent us from detecting this error.

add "to nuon" enumeration of possible styles (#12591)
# Description
in order to change the style of the _serialized_ NUON data,
`nuon::to_nuon` takes three mutually exclusive arguments, `raw: bool`,
`tabs: Option<usize>` and `indent: Option<usize>` 🤔
this begs to use an enumeration with all possible alternatives, right?

this PR changes the signature of `nuon::to_nuon` to use `nuon::ToStyle`
which has three variants
- `Raw`: no newlines
- `Tabs(n: usize)`: newlines and `n` tabulations as indent
- `Spaces(n: usize)`: newlines and `n` spaces as indent

# User-Facing Changes
the signature of `nuon::to_nuon` changes from
```rust
to_nuon(
    input: &Value,
    raw: bool,
    tabs: Option<usize>,
    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>
```
to
```rust
to_nuon(
    input: &Value,
    style: ToStyle,
    span: Option<Span>
) -> Result<String, ShellError>
```

create nuon crate from from nuon and to nuon (#12553)
# Description
playing with the NUON format in Rust code in some plugins, we agreed
with the team it was a great time to create a standalone NUON format to
allow Rust devs to use this Nushell file format.

> **Note**
> this PR almost copy-pastes the code from
`nu_commands/src/formats/from/nuon.rs` and
`nu_commands/src/formats/to/nuon.rs` to `nuon/src/from.rs` and
`nuon/src/to.rs`, with minor tweaks to make then standalone functions,
e.g. remove the rest of the command implementations

### TODO
- [x] add tests
- [x] add documentation

# User-Facing Changes
devs will have access to a new crate, `nuon`, and two functions,
`from_nuon` and `to_nuon`
```rust
from_nuon(
    input: &str,
    span: Option<Span>,
) -> Result<Value, ShellError>
```
```rust
to_nuon(
    input: &Value,
    raw: bool,
    tabs: Option<usize>,
    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>
```

# Tests + Formatting
i've basically taken all the tests from
`crates/nu-command/tests/format_conversions/nuon.rs` and converted them
to use `from_nuon` and `to_nuon` instead of Nushell commands
- i've created a `nuon_end_to_end` to run both conversions with an
optional middle value to check that all is fine

> **Note** 
> the `nuon::tests::read_code_should_fail_rather_than_panic` test does
give different results locally and in the CI...
> i've left it ignored with comments to help future us :)

Make group-by return errors in closure (#12508)
# Description
When a closure if provided to `group-by`, errors that occur in the
closure are currently ignored. That is, `group-by` will fall back and
use the `"error"` key if an error occurs. For example, the code snippet
below will group all `ls` entries under the `"error"` column.
```nushell
ls | group-by { get nope } 
```

This PR changes `group-by` to instead bubble up any errors triggered
inside the closure. In addition, this PR also does some refactoring and
cleanup inside `group-by`.

# User-Facing Changes
Errors are now returned from the closure provided to `group-by` instead
of falling back to the `"error"` group/key.

Refactor first and last (#12478)
# Description

- Refactors `first` and `last` using `Vec::truncate` and `Vec::drain`.
- `std::mem::take` was also used to eliminate a few `Value` clones.
- The `NeedsPositiveValue` error now uses the span of the `rows`
argument instead of the call head span.
- `last` now errors on an empty stream to match `first` which does
error.
-  Made metadata preservation more consistent.

Isolate tests from user config (#12437)
# Description
This is an attempt to isolate the unit tests from whatever might be in
the user's config. If the
user's config is broken in some way or incompatible with this version
(for example, especially if
there are plugins that aren't built for this version), tests can
spuriously fail.

This makes tests more reliably pass the same way they would on CI even
if the user has config, and
should also make them run faster.

I think this is _good enough_, but I still think we should have a
specific config dir env variable for nushell specifically (rather than
having to use `XDG_CONFIG_HOME`, which would mess with other things) and
then we can just have `nu-test-support` set that to a temporary dir
containing the shipped default config files.

Fix #12391: mkdir uses process startup directory instead of current script directory (#12394)
# Description

This fixes #12391.

nushell/nushell@87c5f6e455 accidentally introduced a bug where the path
was not being properly
expanded according to the cwd. This makes both 'touch' and 'mkdir' use
globs just like the rest of
the commands to preserve tilde behavior while still expanding the paths
properly.

This doesn't actually expand the globs. Should it?

# User-Facing Changes

- Restore behavior of `mkdir`, `touch`
- Help text now says they can take globs, but they won't actually expand
them, maybe this should be changed

# Tests + Formatting

Regression tests added.


# After Submitting

This is severe enough and should be included in the point release.

mkdir umask fix (#12354)

Fixes how the directory permissions are calculated in `mkdir`. Instead
of subtraction, the umask is actually used as a mask via negation

into sqlite: Fix insertion of null values (#12328)
# Description

In #10232, the allowed input types were changed to be stricter, only
allowing records with types that can easily map onto sqlite equivalents.
Unfortunately, null was left out of the accepted input types, which
makes inserting rows with null values impossible.

This change fixes that by accepting null values as input.

One caveat of this is that when the command is creating a new table, it
uses the first row to infer an appropriate sqlite schema. If the first
row contains a null value, then it is impossible to tell which type this
column is supposed to have.

Throwing a hard error seems undesirable from a UX perspective, but
guessing can lead to a potentially useless database if we guess wrong.

So as a compromise, for null columns, we will assume the sqlite type is
TEXT and print a warning so the user knows. For the time being, if users
can't avoid a first row with null values, but also wants the right
schema, they are advised to create their table before running `into
sqlite`.

A future PR can add the ability to explicitly specify a schema.

Fixes #12225

* Tests added to cover expected behavior around insertion of null values

This was down to the use of `eval_block` instead of
`eval_block_with_early_return`. We may want to reconsider how we

remaining commands that can invoke a closure block, if they properly
handle `ShellError::Return` as a passing of a `Value`

Change default algorithm in detect columns (#12277)
# Description
@fdncred found another histogram based algorithm to detect columns, and
rewrite it in rust: https://github.com/fdncred/guess-width

I have tested it manually, and it works good with `df`, `docker ps`,
`^ps`. This pr is going to use the algorithm in `detect columns`

Fix: #4183

The pitfall of new algorithm:
1. it may not works well if there isn't too much rows of input
2. it may not works well if the length of value is less than the header
to value, e.g:
```
c1 c2 c3 c4 c5
a b c d e
g h i j k
g a a q d
a v c q q | detect columns
```
In this case, users might need to use ~~`--old`~~ `--legacy` to make it
works well.

# User-Facing Changes
User might need to add ~~`--old`~~ `--legacy` to scripts if they find
`detect columns` in their scripts broken.

Initial implementation for uutils uname (#11684)
Hi,
This PR aims at implementing the first iteration for `uname` using
`uutils`. Couple of things:
* Currently my [PR](https://github.com/uutils/coreutils/pull/5921) to
make the required changes is pending in `uutils` repo.
* I guess the number of flags has to be investigated. Still the tests
cover all of them.

ls, rm, cp, open, touch, mkdir: Don't expand tilde if input path is quoted string or a variable. (#12232)
# Description
Fixes:  #11887
Fixes: #11626

This pr unify the tilde expand behavior over several filesystem relative
commands. It follows the same rule with glob expansion:
|  command  |  result |
| ----------- |  ------ |
| ls ~/aaa  | expand tilde
| ls "~/aaa"  | don't expand tilde
| let f = "~/aaa"; ls $f | don't expand tilde, if you want to: use `ls
($f \| path expand)`
| let f: glob = "~/aaa"; ls $f | expand tilde, they don't expand on
`mkdir`, `touch` comamnd.

Actually I'm not sure for 4th item, currently it's expanding is just
because it followes the same rule with glob expansion.

### About the change
It changes `expand_path_with` to accept a new argument called
`expand_tilde`, if it's true, expand it, if not, just keep it as `~`
itself.

# User-Facing Changes
After this change, `ls "~/aaa"` won't expand tilde.

Initial --params implementation (#12249)
# Description
This PR adds a `--params` param to `query db`. This closes #11643.

You can't combine both named and positional parameters, I think this
might be a limitation with rusqlite itself. I tried using named
parameters with indices like `{ ':named': 123, '1': "positional" }` but
that always failed with a rusqlite error. On the flip side, the other
way around works: for something like `VALUES (:named, ?)`, you can treat
both as positional: `-p [hello 123]`.

This PR introduces some very gnarly code repetition in
`prepared_statement_to_nu_list`. I tried, I swear; the compiler wasn't
having any of it, it kept telling me to box my closures and then it said
that the reference lifetimes were incompatible in the match arms. I gave
up and put the mapping code in the match itself, but I'm still not
happy.

Another thing I'm unhappy about: I don't like how you have to put the
`:colon` in named parameters. I think nushell should insert it if it's
[missing](https://www.sqlite.org/lang_expr.html#parameters). But this is
the way [rusqlite
works](https://docs.rs/rusqlite/latest/rusqlite/trait.Params.html#example-named),
so for now, I'll let it be consistent. Just know that it's not really a
blocker, and it isn't a compatibility change to later make `{ colon: 123
}` work, without the quotes and `:`. This would require allocating and
turning our pretty little `&str` into a `String`, though

# User-Facing Changes
Less incentive to leave yourself open to SQL injection with statements
like `query db $"INSERT INTO x VALUES \($unsafe_user_input)"`.
Additionally, the `$""` syntax being annoying with parentheses plays in
our favor, making users even more likely to use ? with `--params`.

Fix usage of --tabs flag while converting to json (#12115) (#12251)
closes #12115 

# Description
This fix addresses a bug where the --tabs flag couldn't be utilized due
to improper handling of the tab quantity provided by the user.
Previously, the code mistakenly attempted to convert the tab quantity to
a boolean value, leading to a conversion error. The resolution involves
adjusting the condition clauses to properly validate the presence of the
flag's value. Now, the code checks whether the get_flag() function
returns a value or None associated with the --tabs flag. This adjustment
enables the --tabs flag to function correctly, triggering the
appropriate condition and allowing the conversion to proceed as
expected. Similarly, the fix applies to the --indent flag. Additionally,
a default case was added, and the conversion now works properly without
flags. Two tests were added to validate the corrected behavior of these
flags.

# User-Facing Changes
Now the conversion should work properly instead of displaying an error.

IO and redirection overhaul (#11934)
# Description
The PR overhauls how IO redirection is handled, allowing more explicit
and fine-grain control over `stdout` and `stderr` output as well as more
efficient IO and piping.

To summarize the changes in this PR:
- Added a new `IoStream` type to indicate the intended destination for a
pipeline element's `stdout` and `stderr`.
- The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to
avoid adding 6 additional arguments to every eval function and
`Command::run`. The `stdout` and `stderr` streams can be temporarily
overwritten through functions on `Stack` and these functions will return
a guard that restores the original `stdout` and `stderr` when dropped.
- In the AST, redirections are now directly part of a `PipelineElement`
as a `Option<Redirection>` field instead of having multiple different
`PipelineElement` enum variants for each kind of redirection. This
required changes to the parser, mainly in `lite_parser.rs`.
- `Command`s can also set a `IoStream` override/redirection which will
apply to the previous command in the pipeline. This is used, for
example, in `ignore` to allow the previous external command to have its
stdout redirected to `Stdio::null()` at spawn time. In contrast, the
current implementation has to create an os pipe and manually consume the
output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`,
etc.) have precedence over overrides from commands.

This PR improves piping and IO speed, partially addressing #10763. Using
the `throughput` command from that issue, this PR gives the following
speedup on my setup for the commands below:
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| --------------------------- | -------------:| ------------:|
-----------:|
| `throughput o> /dev/null` | 1169 | 52938 | 54305 |
| `throughput \| ignore` | 840 | 55438 | N/A |
| `throughput \| null` | Error | 53617 | N/A |
| `throughput \| rg 'x'` | 1165 | 3049 | 3736 |
| `(throughput) \| rg 'x'` | 810 | 3085 | 3815 |

(Numbers above are the median samples for throughput)

This PR also paves the way to refactor our `ExternalStream` handling in
the various commands. For example, this PR already fixes the following
code:
```nushell
^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world"
```
This returns an empty list on 0.90.1 and returns a highlighted "hello
world" on this PR.

Since the `stdout` and `stderr` `IoStream`s are available to commands
when they are run, then this unlocks the potential for more convenient
behavior. E.g., the `find` command can disable its ansi highlighting if
it detects that the output `IoStream` is not the terminal. Knowing the
output streams will also allow background job output to be redirected
more easily and efficiently.

# User-Facing Changes
- External commands returned from closures will be collected (in most
cases):
  ```nushell
  1..2 | each {|_| nu -c "print a" }
  ```
This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n"
and then return an empty list.

  ```nushell
  1..2 | each {|_| nu -c "print -e a" }
  ```
This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used
to return an empty list and print "a\na\n" to stderr.

- Trailing new lines are always trimmed for external commands when
piping into internal commands or collecting it as a value. (Failure to
decode the output as utf-8 will keep the trailing newline for the last
binary value.) In the current nushell version, the following three code
snippets differ only in parenthesis placement, but they all also have
different outputs:

  1. `1..2 | each { ^echo a }`
     ```
     a
     a
     ╭────────────╮
     │ empty list │
     ╰────────────╯
     ```
  2. `1..2 | each { (^echo a) }`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │ 1 │ a │
     ╰───┴───╯
     ```
  3. `1..2 | (each { ^echo a })`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │   │   │
     │ 1 │ a │
     │   │   │
     ╰───┴───╯
     ```

  But in this PR, the above snippets will all have the same output:
  ```
  ╭───┬───╮
  │ 0 │ a │
  │ 1 │ a │
  ╰───┴───╯
  ```

- All existing flags on `run-external` are now deprecated.

- File redirections now apply to all commands inside a code block:
  ```nushell
  (nu -c "print -e a"; nu -c "print -e b") e> test.out
  ```
This gives "a\nb\n" in `test.out` and prints nothing. The same result
would happen when printing to stdout and using a `o>` file redirection.

- External command output will (almost) never be ignored, and ignoring
output must be explicit now:
  ```nushell
  (^echo a; ^echo b)
  ```
This prints "a\nb\n", whereas this used to print only "b\n". This only
applies to external commands; values and internal commands not in return
position will not print anything (e.g., `(echo a; echo b)` still only
prints "b").

- `complete` now always captures stderr (`do` is not necessary).

Remove feat extra and include in default (#12140)
# Description
The intended effect of the `extra` feature has been undermined by
introducing the full builds on our release pages and having more
activity on some of the extra commands.

To simplify the feature matrix let's get rid of it and focus our effort
on truly either refining a command to well-specified behavior or
discarding it entirely from the `nu` binary and moving it into plugins.

## Details
- Remove `--features extra` from CI
- Don't explicitly name `extra` in full build wf
- Remove feature extra from build-help scripts
- Update README in `nu-cmd-extra`
- Remove feature `extra`
- Fix previously dead `format pattern` tests
- Relax signature of `to html`
- Fix/ignore `html::test_no_color_flag`
- Remove dead features from `version`
- Refine `to html` type signature

# User-Facing Changes
The commands that were previously only available when building with
`--features extra` will now be available to everyone. This increases the
number of dependencies slightly but has a limited impact on the overall
binary size.

# Tests + Formatting
Some tests that were left in `nu-command` during cratification were dead
because the feature was not passed to `nu-command` and only to
`nu-cmd-lang` for feature-flag mention in `version`.
Those tests have now been either fixed or ignored in one case.

# After Submitting
There may be places in the documentation where we point to `--features
extra` that will now be moot (apart from the generated command help)

This PR refactors `nu-check` and makes it possible to check module
directories. Also removes the requirement for files to end with .nu: It
was too limiting for module directories and there are executable scripts
[around](https://github.com/nushell/nu_scripts/tree/main/make_release/release-note)
that do not end with .nu, it's a common practice for scripts to omit it.

Other changes are:
* Removed the `--all` flag and heuristic parse because these are
irrelevant now when module syntax is a subset of script syntax (i.e.,
every module can be parsed as script).
* Reduced code duplication and in general tidied up the code
* Replaced unspanned errors with spanned ones.

Change the ignore command to use drain() instead of collecting a value (#12120)
# Description

Change the `ignore` command to use `drain()` instead of collecting a
value.

This saves memory usage when piping a lot of output to `ignore`. There's
no reason to keep the output in memory if it's going to be discarded
anyway.

This command mixes input from multiple sources and sends items to the
final stream as soon as they're available. It can be called as part of a
pipeline with input, or it can take multiple closures and mix them that
way.

See `crates/nu-command/tests/commands/interleave.rs` for a practical
example. I imagine this will be most often used to run multiple commands
in parallel and print their outputs line-by-line. A stdlib command could
potentially use `interleave` to make this particular use case easier.

It's quite common to wish that nushell had a command for running things
in the background, and instead of providing job control, this provides
an alternative to some use cases for that by just allowing multiple
commands to run simultaneously and direct their output to the same
place.

This enables certain things that are not possible with `par-each` - for
example, you may wish to run `make` across several projects in parallel:

```nushell
(ls projects).name | par-each { |project| cd $project; make }
```

This works well enough, but the output will only be available after each
`make` command finishes. `interleave` allows you to get each line:

```nushell
interleave ...(
  (ls projects).name | each { |project|
    {
      cd $project
      make | lines | each { |line| {project: $project, out: $line} }
    }
  }
)
```

The result of this is a stream that you could process further - for
example, by saving to a text file.

Note that the closures themselves are not run in parallel. The initial
execution happens serially, and then the streams are consumed in
parallel.

Fix for #11757.
The main issue in #11757 is I tried to copy the timestamp from one
directory to another only to realize that did not work whereas the
coreutils `^touch` had no problems. I thought `--reference` just did not
work, but apparently the whole `touch` command could not work on
directories because
`OpenOptions::new().write(true).create(true).open(&item)` tries to
create `touch`'s target in advance and then modify its timestamps. But
if the target is a directory that already exists then this would fail
even though the crate used for working with timestamps, `filetime`,
already works on directories.

I don't believe this should change any existing valid behaviors. It just
changes a non-working behavior.

This is inspired by the Unix tee command, but significantly more
powerful. Rather than just writing to a file, you can do any kind of
stream operation that Nushell supports within the closure.

The equivalent of Unix `tee -a file.txt` would be, for example, `command
| tee { save -a file.txt }` - but of course this is Nushell, and you can
do the same with structured data to JSON objects, or even just run any
other command on the system with it.

A `--stderr` flag is provided for operating on the stderr stream from
external programs. This may produce unexpected results if the stderr
stream is not then also printed by something else - nushell currently
doesn't. See #11929 for the fix for that.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

If someone was using the system `tee` command, they might be surprised
to find that it's different.

Glob: don't allow implicit casting between glob and string (#11992)
# Description
As title, currently on latest main, nushell confused user if it allows
implicit casting between glob and string:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test $x
```
It always expand the glob although `$x` is defined as a string.
This pr implements a solution from @kubouch :
> We could make it really strict and disallow all autocasting between
globs and strings because that's what's causing the "magic" confusion.
Then, modify all builtins that accept globs to accept oneof(glob,
string) and the rules would be that globs always expand and strings
never expand

# User-Facing Changes
After this pr, user needs to use `into glob` to invoke `glob-test`, if
user pass a string variable:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test ($x | into glob)
```
Or else nushell will return an error.
```
 3 │ glob-test $x
   ·           ─┬
   ·            ╰── can't convert string to glob
