To csv fix (#7850)
# Description

Fixes #7800 . 
`to csv` and `to tsv` no longer:
- accept anything but records and tables as input,
- accept lists that are not tables,
- accept tables and records with values that are not primitives (other
lists, tables and records).

# User-Facing Changes

Using `to csv` and `to tsv` on any of inputs mentioned above will result
in `cant_convert` error.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

Fix pipeline stall in do during capture and remove excessive redirections (#7204)
Currently, if you run `do -i { sudo apt upgrade }`, stdin gets swallowed
and doesn't let you respond yes/no to the upgrade question. This PR
fixes that, but runs into https://github.com/nushell/nushell/issues/7205
so the tests fail.

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

Fixes: #7786

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

# What happened internally?
Take the following as example:
```
❯ def foobar [] { 
    'hello' out> /tmp/output.1
    'world' out> /tmp/output.2
}
```

## Before:
```
LiteBlock { block: [
    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: [
    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40824, end: 40831 }] }),
        Redirection(Span { start: 40832, end: 40836 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40837, end: 40850 }] })] 
    },
    LitePipeline { commands: [
        Command(None, LiteCommand { comments: [], parts: [Span { start: 40854, end: 40861 }] }), 
        Redirection(Span { start: 40862, end: 40866 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 40867, end: 40880 }] })] 
    }

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
```rust
LiteBlock {
    block: [
        LitePipeline { commands: [
            Command(None, LiteCommand { comments: [], parts: [Span { start: 39041, end: 39044 }] }),
            // actually the span of first Redirection is wrong too..
            Redirection(Span { start: 39058, end: 39062 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
            Redirection(Span { start: 39058, end: 39062 }, Stderr, LiteCommand { comments: [], parts: [Span { start: 39063, end: 39070 }] })
        ]
    }]
}
```
### LiteBlock after
```rust
LiteBlock {
    block: [
        LitePipeline { commands: [
            Command(
                None, 
                LiteCommand { comments: [], parts: [Span { start: 38525, end: 38528 }] }),
                // new one! two Redirection merged into one SeparateRedirection.
                SeparateRedirection { 
                    out: (Span { start: 38529, end: 38533 }, LiteCommand { comments: [], parts: [Span { start: 38534, end: 38541 }] }),
                    err: (Span { start: 38542, end: 38546 }, LiteCommand { comments: [], parts: [Span { start: 38547, end: 38554 }] })
                }
        ]
    }]
}
```

### Block before

            expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),

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
```

EDIT: This also changes the semantics of `get`/`select` `-i` somewhat.
I've decided to leave it like this because it works more intuitively
with `default` and `compact`.
BEFORE:
```
〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon
null
```
AFTER:
```
〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon
[[foo]; [null], [null], [null]]
```

To toml fix (#7597)
# Description

Fixes #7510 .
Remove support for tables from `to toml` command and update description.
Previously, as indicated in #7510 , a table could be converted to toml
and would result in this invalid toml:


![image](https://user-images.githubusercontent.com/17511668/209443930-c3dd3a3f-5ffd-4273-9c10-acbb345c788e.png)

This commit removes functionality of serializing tables and now `to
toml` produces an error:


![image](https://user-images.githubusercontent.com/17511668/209443975-be119465-8946-4644-8994-489ca94f6006.png)

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


![image](https://user-images.githubusercontent.com/17511668/209443995-1590d044-a790-4be3-a967-b26292a6e70c.png)

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


![image](https://user-images.githubusercontent.com/17511668/209444014-7cfe8f8e-ad8a-4845-a151-24df6b99a1a2.png)

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:


![image](https://user-images.githubusercontent.com/17511668/209449482-5d876074-fc5b-4b21-b8a5-64e643a50083.png)


# 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
╭───┬─────╮

│ 1 │ foo │

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

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