Revert range expansion for to nuon (#8210)
# Description

The code to generate the nuon format supports writing range literals,
which obviates the need to expand the range as added in #8047

# User-Facing Changes

`to nuon` will still output ranges as literals

# Tests + Formatting

- Add test for `to nuon` range output
- Add `from nuon` test for range

pipe binary data to external commands (#8058)
Fixes #7615 

# Description

When calling external commands, we create a table from the pipeline data
to handle external commands expecting paginated input. When a binary
value is made into a table, we convert the vector of bytes representing
the binary bytes into a pretty formatted string. This results in the
pretty formatted string being sent to external commands instead of the
actual binary bytes. By checking whether the stdout of the call is being
redirected, we can decide whether to send the raw binary bytes or the
pretty formatted output when creating a table command.

# User-Facing Changes

When passing binary values to external commands, the external command
will receive the actual bytes instead of the pretty printed string. Use
cases that don't involve piping a binary value into an external command
are unchanged.

cp progress bar implementation (#8012)
# NOTE
Clean duplicate of #7825
Sorry about all the mess guys... I got confuse with GitHub and and ended
up mankind that mess.
This the same code I just cleaned the commits.

# Description
Progress bar implementation for the `cp` command. Now if the flag `-p`
or `--progress` is set, then the user will be able to see the progress
of the file or files being copy


![progressbar_cp01](https://user-images.githubusercontent.com/38369407/213899494-0f6a4aa9-ee82-48c3-a1f1-1816f3fc1d9c.jpg)

![progressbar_cp02](https://user-images.githubusercontent.com/38369407/213899497-2f9e6e8c-fdd9-400b-bd8d-c59899ae0368.jpg)

# User-Facing Changes
A new flag (`--progress` `-p`) was added to the `cp` command 
Examples:
```nu
cp -p test_file.txt test_folder_1\
cp -r -p test_folder\* test_folder_1\
cp -r -p -i test_folder\* test_folder_1\
```

## Notes 
- The progress bar uses `std::io::{Read, Write}` instead of
`std::fs::copy` to get the progress. that means that when the progress
bar is used the copy process might be a bit slower.
- Progress bar for symbolic links TBD: Since symbolic links are usually
very light I think is not worth it to duplicate the function
`copy_symlink` just to add a progress bar that will be so fast to the
point is not needed, but.. for consistency purposes we might need to
added it, In that case I would have to pass the variable `progress` by
parameter (to not duplicate code unnecessary). If I do that i would have
to pass the `progress` var to every function to respect `copy_impl: impl
Fn(PathBuf, PathBuf, Span)`. Please let me know if this is not clear :p

fixes a def parsing bug with a default list (#8096)
# Description

This PR fixes a bug where a default list in a custom command parameter
wasn't being accepted. The reason was because it was comparing specific
types of list like `list<any>` != `list<string>`. So, this PR attempts
to fix that.

### Before

```

Error: nu::parser::assignment_mismatch (link)

string | fill counts clusters, not graphemes; and doesn't count ANSI escape codes (#8134)
Enhancement of new `fill` command (#7846) to handle content including
ANSI escape codes for formatting or multi-code-point Unicode grapheme
clusters.
In both of these cases, the content is (many) bytes longer than its
visible length, and `fill` was counting the extra bytes so not adding
enough fill characters.

# Description

This script:
```rust
# the teacher emoji `\u{1F9D1}\u{200D}\u{1F3EB}` is 3 code points, but only 1 print position wide.
echo "This output should be 3 print positions wide, with leading and trailing `+`"
$"\u{1F9D1}\u{200D}\u{1F3EB}" | fill -c "+" -w 3 -a "c"

echo "This output should be 3 print positions wide, with leading and trailing `+`"
$"(ansi green)a(ansi reset)" | fill -c "+" -w 3 -a c
echo ""
```

Was producing this output:
```rust
This output should be 3 print positions wide, with leading and trailing `+`
🧑‍🏫

This output should be 3 print positions wide, with leading and trailing `+`
a
```

After this PR, it produces this output:
```rust
This output should be 3 print positions wide, with leading and trailing `+`
+🧑‍🏫+

This output should be 3 print positions wide, with leading and trailing `+`
+a+
```

former behavior. I have one such in my prompt string that I can now
revert.

# After Submitting

`fill` command not documented in the book, and it still talks about `str
lpad/rpad`. I'll fix.

Note added dependency on a new library `print-positions`, which is an
iterator that yields a complete print position (cluster + Ansi sequence)
per call. Should this be vendored?

Bare word improvements (#8066)
# Description

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

Move some from xxx commands to plugin (#7942)
# Description

From nushell 0.8 philosophy:
https://github.com/nushell/nushell.github.io/blob/main/contributor-book/philosophy_0_80.md#core-categories

> The following categories should be moved to plugins:
Uncommon format support

So this pr is trying to move following commands to plugin:
- [X] from eml
- [x] from ics
- [x] from ini
- [x] from vcf

And we can have a new plugin handles for these formatting, currently
it's implemented here:

https://github.com/WindSoilder/nu_plugin_format

The command usage should be the same to original command.

If it's ok, the plugin can support more formats like
[parquet](https://github.com/fdncred/nu_plugin_from_parquet), or [EDN
format](https://github.com/nushell/nushell/issues/6415), or something
else.

Just create a draft pr to show what's the blueprint looks like, and is
it a good direction to move forward?

Add dfr to dataframe cmds (#7998)
# Description

This PR tries to resolve the overloading issue by going back to our
original naming convention for dataframes. So, this PR renames all
dataframe commands with a prefix of `dfr`. Some commands like `open-df`
were renamed to `dfr open` and things like `into df` were renamed `dfr
into-df`. I'm sure we can optimize naming a bit, but it seems to compile
now.

# User-Facing Changes

make do -i works with liststream (#7889)
# Description

Fixes: #7874 

It's because `do -i` doesn't handles `Pipeline::ListStream`
data(especially there is Value::Error inside the stream)

To fix it, we need to iterate through `ListStream`, check if there is
`Value::Error`. If so, just returns `Pipeline::empty()`

Let redirection keep exit code (#7848)
# Description

Fixes: #7828

We delegate to `save` command to finish redirection, then if it runs to
success, the relative exit code is set to 0. To fix it, in redirection
context, we take exit_code stream before sending it to `save` command,
than manually returns `PipelineData::ExternalStream` to make nushell set
relative code properly.

Expose filtering by file type in glob (#7834)
# Description

Add flags for filtering the output of `glob` by file type. I find myself
occasionally wanting to do this, and getting a file's
[file_type](https://docs.rs/wax/latest/wax/struct.WalkEntry.html#method.file_type)
is presumably fast to do as it doesn't have to go through the fallible
metadata method.

The design of the signature does concern me; it's not as readable as a
filter or "include" type list would be. They have to be filtered one by
one, which can be annoying if you only want files `-D -S`, or only want
folders `-F -S`, or only want symlinks `--butwhy?`. I considered
SyntaxShape::Keyword for this but I'll just defer to comments on this PR
if they pop up.

I'd also like to bring up performance since including these flags
technically incurs a `.filter` penalty on all glob calls, which could be
optimized out if we added a branch for the no-filters case. But in
reality I'd expect the file system to be the bottleneck and the flags to
be pretty branch predictor friendly, so eh

# User-Facing Changes
Three new flags when using `glob` and a slightly more cluttered help
page. No breaking changes, I hope.

Fix multi-line redirection inside a block (#7808)
# Description

Fixes: #7786

The issue is because the lite block is wrong while converting from lex

# What happened internally?
Take the following as example:
```

    'world' out> /tmp/output.2
}
```

## Before:
```

    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40900, end:40907 }] }),
        Redirection(Span { start: 40908, end: 40912 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40913, end: 40926 }] })]
    },
    LitePipeline { commands: [
        Redirection(Span { start: 40908, end: 40912 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40929, end: 40936 }] }),   // this is wrong, should be command.
        Redirection(Span { start: 40937, end: 40941 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40942, end: 40955 }] })]
    }] }
```

## After:
```
LiteBlock { block: [

make save stream on list stream data (#7675)
# Description

Closes: #7590

# User-Facing Changes

So the following command
```
1..100 | each { |i| sleep 400ms; $i} | save --raw -f output.txt
```

Will stream data to `output.txt`

But I'm note sure how to make a proper test for it, so I leave with no
new test cases..

Also rename from `string_binary_list_value_to_bytes ` to
`value_to_bytes` to accepts more Value type.

Rename to url command to url build-query (#7702)
# Description

Refactor command: "to url" in: "to url query". Changed usage sentence.
Closes: #7495

# User-Facing Changes

Now we get a query string from a record or table by using command: "to
url query".

```
> help to url query
Convert record or table into query string applying percent-encoding.

Usage:
  > to url query

Flags:
  -h, --help - Display the help message for this command

Signatures:
  <record> | to url query -> <string>
  <table> | to url query -> <string>

Examples:
  Outputs a query string representing the contents of this record
  > { mode:normal userid:31415 } | to url query

  Outputs a query string representing the contents of this 1-row table
  > [[foo bar]; ["1" "2"]] | to url query

  Outputs a query string representing the contents of this record
  > {a:"AT&T", b: "AT T"} | to url query
```

# Tests + Formatting

Added this test:
```
Example {
    description: "Outputs a query string representing the contents of this record",
    example: r#"{a:"AT&T", b: "AT T"} | to url query"#,
    result: Some(Value::test_string("a=AT%26T&b=AT+T")),
},
```
to ensure percent-encoding.

Fix typos and use more idiomatic assertions (#7755)
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.

Trim quotes when shelling out to cmd.exe (#7740)
Closes #6337 and #5366. Prior to this PR, when "shelling out" to cmd.exe
on Windows we were not trimming quotes correctly:

```bash
〉^echo "foo"
\"foo\"
```
After this change, we do:
```bash
〉^echo "foo"
foo
```

### Breaking Change

I ended up removing `dir` from the list of supported cmd.exe internal
commands as part of this PR.

For this PR, I extracted the argument-cleaning-and-expanding code from
`spawn_simple_command()` for reuse in `spawn_cmd_command()`. This means
that we now expand globs, which broke some tests for the `dir` cmd.exe
internal command.

I probably could have kept the tests working, but... tbh, I don't think
it's worth it. I don't want to make the `cmd.exe` functionality any more
complicated than it already is, and calling `dir` from Nu is always
going to be weird+hacky compared to `ls`.

Support redirect err and out to different streams (#7685)
# Description

Closes: #7364 

# User-Facing Changes

Given the following shell script:
```bash
x=$(printf '=%.0s' {1..100})
echo $x
echo $x 1>&2
```

It supports the following command:
```
bash test.sh out> out.txt err> err.txt
```

Then both `out.txt` and `err.txt` will contain `=`(100 times)

## About the change

The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SeparateRedirection` if we meet two Redirection
token(which is generated by `lex` function),
During converting from lite block to block,
`LiteElement::SeparateRedirection` will be converted to
`PipelineElement::SeparateRedirection`.

Then in the block eval process, if we get
`PipelineElement::SeparateRedirection`, we invoke `save` command with
`--stderr` arguments to acthive our behavior.



## What happened internally?
Take the following command as example:
```
^ls out> out.txt err> err.txt
```

lex parsing result(`Tokens`) are not changed, but `LiteBlock` and
`Block` is changed after this pr.

### LiteBlock before

        ]

Remove math eval command (#7284)
Reasoning: 

Most missing math commands are implemented with #7258.
The `meval` crate itself declares that it doesn't strive to stringent
standards (https://docs.rs/meval/latest/meval/#related-projects).
For example no particular special casing or transformations are
performed to ensure numerical stability. It uses the same rust `std`
library functions we use or have access to (and `f64`).
While the command call syntax in nushell may be a bit more verbose,
having a single source of truth and common commands is beneficial.
Furthermore the `math` commands can themselves implement broadcasting
over lists (or table columns).

Closes #7073

Removed dependencies:
- `meval`
- `nom 1.2.4` (duplicate)

User-Facing Changes:

Scripts using `math eval` will break. 
We remove a further `eval` like behavior to get results through runtime evaluation (albeit limited in scope)

Tests:

- Updated tests that internally used `math eval`.
- Removed one test that primarily used `math eval` to obtain a result from `str join`

Make stream info visible to users in describe (#7589)
Closes #7581.

After this PR, `describe` shows `(stream)` next to input that arrived at
`describe` as a `ListStream`:
```bash
〉ls | describe
table<name: string, type: string, size: filesize, modified: date> (stream)
〉[1 2 3] | each {|i| $i} | describe
list<int> (stream)
```

`describe` must collect all items of the stream to display type
information for lists and tables. If users need to avoid collecting
input, they can use the `-n`/`--no-collect` flag:

```bash
〉[1 2 3] | each {|i| $i} | describe --no-collect
stream
```

The `from toml` command already acknowledges the fact that toml can
contain only records as indicated in its signature

Now help of `to toml` reflects this feature of format as well:

Additionally new tests were created for `to toml` command. See
`crates\nu-command\tests\format_conversions\toml.rs`.

Also removed undocumented behavior that would accept and validate a
string as toml:

# User-Facing Changes

- Serializing tables to toml now produces error instead of invalid toml
- Updated `to toml` help
- Remove undocumented "validation" (not really user-facing)

Standardise the use of ShellError::UnsupportedInput and ShellError::TypeMismatch and add spans to every instance of the former (#7217)
# Description

* I was dismayed to discover recently that UnsupportedInput and
TypeMismatch are used *extremely* inconsistently across the codebase.
UnsupportedInput is sometimes used for input type-checks (as per the
name!!), but *also* used for argument type-checks. TypeMismatch is also
used for both.
I thus devised the following standard: input type-checking *only* uses
UnsupportedInput, and argument type-checking *only* uses TypeMismatch.
Moreover, to differentiate them, UnsupportedInput now has *two* error
arrows (spans), one pointing at the command and the other at the input
origin, while TypeMismatch only has the one (because the command should
always be nearby)
* In order to apply that standard, a very large number of
UnsupportedInput uses were changed so that the input's span could be
retrieved and delivered to it.
* Additionally, I noticed many places where **errors are not propagated
correctly**: there are lots of `match` sites which take a Value::Error,
then throw it away and replace it with a new Value::Error with
less/misleading information (such as reporting the error as an
"incorrect type"). I believe that the earliest errors are the most
important, and should always be propagated where possible.
* Also, to standardise one broad subset of UnsupportedInput error
messages, who all used slightly different wordings of "expected
`<type>`, got `<type>`", I created OnlySupportsThisInputType as a
variant of it.
* Finally, a bunch of error sites that had "repeated spans" - i.e. where
an error expected two spans, but `call.head` was given for both - were
fixed to use different spans.

Make to text stream ListStreams (#7577)
This PR changes `to text` so that when given a `ListStream`, it streams
the incoming values instead of collecting them all first.

The easiest way to observe/verify this PR is to convert a list to a very
slow `ListStream` with `each`:
```bash
ls | get name | each {|n| sleep 1sec; $n} | to text
```
The `to text` output will appear 1 item at a time.

# Description

Prevent a situation where a `def` can't be run due to a poor choice of

would be caught but `alias "123"` would be permitted.

Fix && quotation in to nuon after proptest fail (#7564)
`proptest` caught a failing test condition for `&&` as a literal string. It requires a quotation to be parsed correctly by current `from nuon`
    
https://github.com/nushell/nushell/actions/runs/3753242377/jobs/6376308675

The change in the parser that now returns an error was introduced by https://github.com/nushell/nushell/pull/7241

This in theory doesn't have to be an error (it is a diagnostic for nushell code) but it is probably better safe than sorry to require quotation here.

- Add a test for `&&` in `to nuon` from proptest fail
- Fix `to nuon` generating invalid `&&` literal
- Add a test for `,` in `to nuon`/`from nuon` cycle
  - Bonus: should already be properly quoted

I'm currently [working on improving cell
paths](https://github.com/nushell/nushell/issues/7498#issuecomment-1356834798),
and I realized that I would need to make several improvements to `into
cellpath` along the lines of Jakub's comment here:
https://github.com/nushell/nushell/pull/7417#issuecomment-1345264955

I don't think `into cellpath` is quite ready for prime-time, and I'd
like to remove it before the upcoming release.

Fix cell path when getting columns of non-records (#7508)
A follow-up to #7497. That change made it so that `get foo` would
eliminate non-record rows; I think that was an unintentional and
undesirable side-effect.

Before #7497:
```bash
〉[$nothing, { item: "foo" }] | get item
╭───┬─────╮
│ 0 │     │
│ 1 │ foo │
╰───┴─────╯
```
After #7497:
```bash
〉[$nothing, {item: "foo"}] | get item
╭───┬─────╮
│ 0 │ foo │
╰───┴─────╯
```

After this PR:
```bash
〉[$nothing, { item: "foo" }] | get item
╭───┬─────╮

Replace row conditions with closures in commands (#7428)
# Description

This PR changes some commands that previously accepted row conditions
(like `$it > 5`) as parameter to accept closures instead. The reasons
are:
a) The commands would need to move into parser keywords in the future
while they feel more like commands to be implemented in Nushell code as
a part of standard library.
b) In scripts, it is useful to store the predicate condition in a
variable which you can't do with row conditions.
c) These commands are not used that often to benefit enough from the
shorter row condition syntax

# User-Facing Changes

The following commands now accept **closure** instead of a **row
condition**:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`

This is a part of an effort to move away from shape-directed parsing.

Move 'where' to parser keywords; Add 'filter' command (#7365)
# 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.

# User-Facing Changes

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

Allow $env and mutable records to be mutated by = (closes #7110) (#7318)
# 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.

New commands: break, continue, return, and loop (#7230)
# Description

This adds `break`, `continue`, `return`, and `loop`.

* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)

Examples:
```
for i in 1..10 {
    if $i == 5 {
       continue
    } 
    print $i
}
```

```
for i in 1..10 {
    if $i == 5 {
        break
    } 
    print $i
}
```

```
def foo [x] {
    if true {
        return 2
    }
    $x
}
foo 100
```

```
loop { print "hello, forever" }

Make catch block a closure w/ access to error (#7228)
A small follow-up to #7221. This changes the `catch` block from a block
to a closure, so that it can access the error returned from the `try`
block. This helps with a common scenario: "the `try` block failed, and I
want to log why it failed."

### Example


![image](https://user-images.githubusercontent.com/26268125/203841966-f1f8f102-fd73-41e6-83bc-bf69ed436fa8.png)

### Future Work

Nu's closure syntax is a little awkward here; it might be nicer to allow
something like `catch err { print $err }`. We discussed this on Discord
and it will require special parser code similar to what's already done
for `for`.

I'm not feeling confident enough in my parser knowledge to make that
change; I will spend some more time looking at the `for` code but I
doubt I will be able to implement anything in the next few days.
Volunteers welcome.

uniq code refactoring (#7188)
# Description

While trying to add a new `uniq-by` command I refactored the `uniq`
command code to understand it and try to reuse. I think this is more
compact and easier to understand.
The part that I think it's a little confusing in this refactor is the
conditions inside `.filters()`, for example: `!flag_show_repeated ||
(value.1 > 1)`. I could use `if (flag_show_repeated) {value.1 > 1} else
{true}` but it is more verbose, what do you think?

PS: Not sure if you like this kind of PR, sorry if not.

# Tests + Formatting

I also added a test where the `uniq` has a table as input.

Error on negative argument of first (#7186)
Fixes a two's complement underflow/overflow when given a negative arg.

Breaking change as it is throwing an error instead of most likely
returning most of the output.

Breaking change:

even before #7178 `last` returned an empty `list<any>` when given
negative indices.
Now this is an

Fixed json parsing (#7175)
# Description

I noticed that some json values are not parsed at the top level, for
example: `null`, `true`, `false`. Although this is a valid json.
```

Error:
  × Error while parsing JSON text
   ╭─[entry #12:1:1]
 1 │ "null" | from json
   ·          ────┬────

Error:

Limited mutable variables (#7089)
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 }
Error: nu::parser::expected_keyword (link)

  × Capture of mutable variable.

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.
