Simplify str trim command (#8205)
### What?

This change removes 3 flags (`--all`, `--both`, and `--format`) from
`str trim`. This is a net reduction of ~450 LoC and `str trim` no longer
depends on `fancy_regex`.

### Why?

I found these flags to be quite confusing when reviewing `str trim`
earlier today:

1. `--all` removes characters even if they're in the centre of the the
string.
- This is arguably not "trimming"! In all programming languages I'm
familiar with, trimming only affects the start and end of a string.
    - If someone needs to do this, `str replace` is more natural IMO
2. `--both` trims from the left and right
- Confusing and unnecessary given that this is also the default
behaviour
3. `--format` replaces multiple spaces with a single space, even in the
centre of the string
- Again, I don't think this falls under the scope of "trimming". IMO
`str replace` is a more natural fit

I believe that `str trim` is simpler and easier to understand after this
change.

### Before

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string
  -a, --all - trims all characters from both sides of the string *and* in the middle
  -b, --both - trims all characters from left and right side of the string
  -f, --format - trims spaces replacing multiple characters with singles in the middle
```

### After

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string

special-case ExternalStream in bytes starts-with (#8203)
# Description
`bytes starts-with` converts the input into a `Value` before running
.starts_with to find if the binary matches. This has two side effects:
it makes the code simpler, only dealing in whole values, and simplifying
a lot of input pipeline handling and value transforming it would
otherwise have to do. _Especially_ in the presence of a cell path to
drill into. It also makes buffers the entire input into memory, which
can take up a lot of memory when dealing with large files, especially if
you only want to check the first few bytes (like for a magic number).

This PR adds a special branch on PipelineData::ExternalStream with a
streaming version of starts_with.

# User-Facing Changes
Opening large files and running bytes starts-with on them will not take
a long time.

# 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

# Drawbacks
Streaming checking is more complicated, and there may be bugs. I tested
it with multiple chunks with string data and binary data and it seems to
work alright up to 8k and over bytes, though.

The existing `operate` method still exists because the way it handles
cell paths and values is complicated. This causes some "code
duplication", or at least some intent duplication, between the value
code and the streaming code. This might be worthwhile considering the
performance gains (approaching infinity on larger inputs).

Another thing to consider is that my ExternalStream branch considers
string data as valid input. The operate branch only parses Binary
values, so it would fail. `open` is kind of unpredictable on whether it
returns string data or binary data, even when passing `--raw`. I think
this can be a problem but not really one I'm trying to tackle in this
PR, so, it's worth considering.

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.

Dependency update: update notify version to v5 (#8114)
# Description

Relative: #8060

While investigating, I found we need to update notify, which is a good
step to remove some duplicate dependencies.

As title, here are some goods and bads after updating:

## Good
keep dependency up to date, and remove duplidate dependency(cfg-if,
winapi) in Cargo.lock.

## Bad
Introduce some breaking changes:
After updating to notify v5, I found that we have to remove `Rename`
events.

But I've testing under notify v4, and it doesn't work good if we running
the following command on MacOS:
```
touch a
mv a b
```
It fires file create event, but no file rename event. So `rename` event
is not really reliable, so I think it's ok for us to remove `Rename`
events.

The reason to remove `--debounce-ms` flag:
It's not provided by defualt file watcher, we can use
[PollWatcher](https://docs.rs/notify/latest/notify/poll/struct.PollWatcher.html),
but it scans filesystem, which is really expensive. So I just remove the
flag.

# User-Facing Changes

1. `--debounce-ms` flag is removed
2. no longer watch `Rename` event.

# Tests + Formatting

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

interrupt input command with Ctrl + C (#8159)
# Description

GH Issue: [#8074](https://github.com/nushell/nushell/issues/8074)

Adding SIGINT Ctrl + C functionality to *most* of the `input` command.
`input` with the flags `--suppress-output` and `--bytes-until` are
executed in raw mode which allows a ^C signal to be caught as it's
input, but an "optionless" call of `input` is using a standard
`read_line()` method that takes a ^C input and clears the buffer of any
data collected before the ^C. I'm more than happy to alter the
"optionless" call but putting it in raw mode hides the user input, so at
the moment that's unchanged.

# User-Facing Changes

Now ^C anywhere in the stdin stream will cause the command to SIGINT (as
long as the command isn't optionless), rather than being read in as part
of the input.
```
/home/rdevenney/projects/open_source/nushell〉input --suppress-output
Error: nu:🐚:io_error (link)

  × I/O error
  help: SIGINT
```

```
/home/rdevenney/projects/open_source/nushell〉input --bytes-until "a"
Error: nu:🐚:io_error (link)

  × I/O error
  help: SIGINT

```

As mentioned above, the default input behavior is the same.

TEST: add the output to the new with-env example (#8148)
Related to #8119.
Should address the review comment by @sholderbach from #8119.


# Description

this PR adds the output to the new example for the `with-env` command
introduced by #8119.

```bash
with-env {X: "Y", W: "Z"} { [$env.X $env.W] }
```
should output
```bash
["Y", "Z"]
```
hence the proposition from @sholderbach, i.e.
```rust
Some(Value::list(
    vec![Value::test_string("Y"), Value::test_string("Z")],
    Span::test_data(),
))
```

# User-Facing Changes

- ✔️ `cargo test --workspace`

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 `+`

```

After this PR, it produces this output:

`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?

DOCUMENTATION: add a new "key-value" example to with-env (#8119)
hello there 👋 😋 

when messing around with `with-env`, looking at the examples, i did not
understand that we could directly run `with-env` with a record as the
argument and not from the input of a pipe 😮

even though the last example, i.e. 
```bash
  Set by row(e.g. `open x.json` or `from json`)
  > '{"X":"Y","W":"Z"}'|from json|with-env $in { [$env.X $env.W] }
```
, is equivalent, just the record comes from the pipe, i thought adding
that explicite new example could be helpful 😌
 
# Description
looking at the single real change of this PR, i.e. 86ef34e90, you can
see i've simply added
```bash
  Set by key-value record
  > with-env {X: "Y", W: "Z"} { [$env.X $env.W] }
```
just before the example above

> **Note**
> i've also added spaces around the '|' in the last examples, from
> ```bash
>   > '{"X":"Y","W":"Z"}'|from json|with-env $in { [$env.X $env.W] }
> ```
> to
> ```bash
>   > '{"X":"Y","W":"Z"}' | from json | with-env $in { [$env.X $env.W] }
> ```
> hopefully making the pipeline a bit easier to read 👍

### hope you like that 😏

since every `ast` command contains spans that will be different on each

relocate debug commands (#8071)
# Description

Now that we've landed the debug commands we were working on, let's
relocate them to an easier place to find all of them. That's what this
PR does.

The only actual code change was changing the `timeit` command to a
`Category::Debug` command. The rest is just moving things around and
hooking them up.

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?

#8027 Hide implementation details in invalid cd call (#8049)
# Description

[GH issue](https://github.com/nushell/nushell/issues/8027)

The current error message for a cd command includes a Debug output of
the `io::Error` being returned from `canonicalize_with`, so it's been
replaced with a more user friendly and readable depiction of the error.

# User-Facing Changes

As described in the issue, I've changed the error message for a cd into
a directory that does not exist from:

Fix hidden env vars not being hidden in closures (#8055)
# Description

This one fixes env not being hidden inside closure, reported in the
conversation under https://github.com/nushell/nushell/issues/6593

https://github.com/nushell/nushell/issues/6593
https://github.com/nushell/nushell/issues/7937 still persist. These
seems a bit more involved and might need hidden env tracking also in the
engine state... I'm not yet sure what's causing it.

Also re-enables some env-related tests and removes unused Value clone.

Benchmark each pipeline element (#7854)
# Description

Adds a `profile` command that profiles each pipeline element of a block
and can also recursively step into child blocks.

# Limitations
* It is implemented using pipeline metadata which currently get lost in
some circumstances (e.g.,
https://github.com/nushell/nushell/issues/4501). This means that the
profiler will lose data coming from subexpressions. This issue will
hopefully be solved in the future.
* It also does not step into individual loop iteration which I'm not
sure why but maybe that's a good thing.

add a new inspect command for more debugging (#8028)
# Description

The purpose of this command is to help to debug pipelines. It works by
allowing you to inject the `inspect` command into a pipeline at any
point. Then it shows you what the input description is and what the
input values are that are passed into `inspect`. With each step it
prints this information out while also passing the value information on
to the next step in the pipeline.


![image](https://user-images.githubusercontent.com/343840/218154064-e107859b-d0da-41c6-8e34-2d717639b81c.png)

This command is kind of a "hack job" because it clones maybe too much
and I had to get creative in order to output two different tables. I'm
sure there are many ways this can be improved or combined into other
commands but I wanted to start here. Note that the `inspect` output is
written to stderr and the normal nushell output is written to stdout. If
we were to output both to stdout, nushell would get confused.

A fill command to replace str lpad and str rpad (#7846)
# Description

The point of this command is to allow you to be able to format ints,
floats, filesizes, and strings with an alignment, padding, and a fill
character, as strings. It's meant to take the place of `str lpad` and
`str rpad`.

```
> help fill
Fill and Align

Search terms: display, render, format, pad, align

Usage:
  > fill {flags}

Flags:
  -h, --help - Display the help message for this command
  -w, --width <Int> - The width of the output. Defaults to 1
  -a, --alignment <String> - The alignment of the output. Defaults to Left (Left(l), Right(r), Center(c/m), MiddleRight(cr/mr))
  -c, --character <String> - The character to fill with. Defaults to ' ' (space)

Signatures:
  <number> | fill -> <string>
  <string> | fill -> <string>

Examples:
  Fill a string on the left side to a width of 15 with the character '─'
  > 'nushell' | fill -a l -c '─' -w 15

  Fill a string on the right side to a width of 15 with the character '─'
  > 'nushell' | fill -a r -c '─' -w 15

  Fill a string on both sides to a width of 15 with the character '─'
  > 'nushell' | fill -a m -c '─' -w 15

  Fill a number on the left side to a width of 5 with the character '0'
  > 1 | fill --alignment right --character 0 --width 5

  Fill a filesize on the left side to a width of 5 with the character '0'
  > 1kib | fill --alignment middle --character 0 --width 10
```

view span & view files commands (#7989)
# Description

This PR does the following:
1. Adds a new command called `view span` - which shows what is at the
location of the span parameters
2. Adds a new command called `view` - which just lists all the `view`
commands.
3. Renames `view-source` to `view source`.
4. Adds a new command called `view files` - which shows you what files
are loaded into nushell's EngineState memory.
5. Added a `Category::Debug` and put these commands (and others) into
it. (`inspect` needs to be added to it, but it's not landed yet)

Spans are important to nushell. One of their uses is to show where
errors are. For instance, in this example, the leader lines pointing to
parts of the command line are able to point to `10`, `/`, and `"bob"`
because each of those items have a span.
```
> 10 / "bob"
Error: nu::parser::unsupported_operation (link)

just a quirk of how tabling works:

Make plugin commands support examples. (#7984)
# Description

As title, we can't provide examples for plugin commands, this pr would
make it possible


# User-Facing Changes

Take plugin `nu-example-1` as example:
```
❯ nu-example-1 -h
PluginSignature test 1 for plugin. Returns Value::Nothing

Usage:
  > nu-example-1 {flags} <a> <b> (opt) ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -f, --flag - a flag for the signature
  -n, --named <String> - named string

Parameters:
  a <int>: required integer value
  b <string>: required string value
  (optional) opt <int>: Optional number
  ...rest <string>: rest value string

Examples:
  running example with an int value and string value
  > nu-example-1 3 bb
```

The examples session is newly added.

## Basic idea behind these changes
when nushell query plugin signatures, plugin just returns it's signature
without any examples, so nushell have no idea about the examples of
plugin commands.
To adding the feature, we just making plugin returns it's signature with
examples.

Before:
```
        1. get signature
         ----------------> 
Nushell ------------------  Plugin
        <-----------------
        2. returns Vec<Signature>
```

After:
```
        1. get signature
        ----------------> 
Nushell ------------------  Plugin
        <-----------------
        2. returns Vec<PluginSignature>
```
        
When writing plugin signature to $nu.plugin-path:
Serialize `<PluginSignature>` rather than `<Signature>`, which would
enable us to serialize examples to `$nu.plugin-path`

## Shortcoming
It's a breaking changes because `Plugin::signature` is changed, and it
requires plugin authors to change their code for new signatures.

Fortunally it should be easy to change, for rust based plugin, we just
need to make a global replace from word `Signature` to word
`PluginSignature` in their plugin project.

Our content of plugin-path is really large, if one plugin have many
examples, it'd results to larger body of $nu.plugin-path, which is not
really scale. A solution would be save register information in other
binary formats rather than `json`. But I think it'd be another story.

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

All dataframe commands are prefixed with dfr.

Windows: handle illegal filenames a little better (#7999)
This PR is an incremental improvement to `ls` when it encounters
'illegal' file paths on Windows. Related:
https://github.com/nushell/nushell/issues/7869

## Context

We have trouble with filenames that Windows doesn't like, for example
[files with a `.` at the end of their
name](https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions).
To make a long story short, the Rust stdlib and several Win32 APIs will
choke if asked to do something with an illegal filepath. This is a
problem because files with illegal names can be created via other means
(like `touch foo.` in MINGW bash).

Previously `ls` would fail completely in a directory with a bad file,
which isn't great. After this PR, bad files get included in `ls` results
but without any metadata columns. This is not quite where we want to be
— eventually we want to be able to display file metadata for _all_ files
(even naughty ones) — but it's an improvement on the status quo.

### Before

### After


![image](https://user-images.githubusercontent.com/26268125/217344373-6b81cc39-50b8-4390-8061-3e570502a784.png)

## Future work

Try the workarounds @ChrisDenton suggested:
https://github.com/nushell/nushell/issues/7869#issuecomment-1405977221

Some info on verbatim paths:
https://users.rust-lang.org/t/understanding-windows-paths/58583

## Testing

I tried to write a test for this, but it looks like our testing sandbox
can't create files with illegal filenames.😔 Here's the code in case it
proves useful someday:

```rust
/// Windows doesn't like certain file names, like file names ending with a period:
/// https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions
/// However, those files can still be created with tools like MINGW bash.
/// We may not be able to get full metadata for those files, but we should test that we can at least include them in ls results
#[test]
#[cfg(windows)]
fn can_list_illegal_files() {
    Playground::setup("ls_test_all_columns", |dirs, sandbox| {
        sandbox.with_files(vec![
            EmptyFile("foo"),
            EmptyFile("bar."),
            EmptyFile("baz"),
        ]);

        let actual = nu!(
            cwd: dirs.test(),
            "ls | length"
        );
        assert_eq!(actual.out, "3");

        let actual = nu!(
            cwd: dirs.test(),
            "ls"
        );
        assert_eq!(actual.out, "1");

        let actual = nu!(
            cwd: dirs.test(),
            "ls | where {|f| $f.name | str ends-with 'bar.'} | length"
        );
        assert_eq!(actual.out, "1");
    })
}
```

report which datetime couldn't be converted (#7980)
# Description

This PR will help report a bad date that can't be converted where the
error message says `* Unable to parse datetime`. This is helpful when
you're converting a big table and it fails somewhere that you really
can't see. I put it in `[]` so that when it's null, you can see that
there should be something there.

Fix for #7933. I've read through code and found the obvious difference
between them, where `each` command calls eval_with_early_return
e89e734ca2/crates/nu-command/src/filters/each.rs (L158),
while `reduce` command uses eval_block
e89e734ca2/crates/nu-command/src/filters/reduce.rs (L143)

That simple change seems to resolve the problem.

Allows the use of `return` in reduce closures, as per example in #7933
description. Arguably it's restoring consistency, than changing user
interface.

```
[1, 2] | reduce --fold null { |it, state|                                                           
::: if $it == 1 {
:::     return 10
::: }
::: return ($it * $state)
::: }
20
```

Remove deprecated --numbered flag from four commands (#7777)
# Description

Remove `--numbered` from ~~`for`~~, `each`, `par-each`, `reduce` and
`each while`. These all provide indexes (numbering) via the optional
second param to their closures.

EDIT: Closes #6986.

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()`

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.

fetch -> http get and post -> http post (#7796)
# Updated description by @rgwood

This PR changes `fetch` to `http get` and `post` to `http post`. `fetch`
and `post` are now deprecated. [I surveyed people on
Discord](https://discord.com/channels/601130461678272522/601130461678272524/1065706282566307910)
and users strongly approved of this change.

# Original Description
This PR is related to #2741 and my first pull request in rust :)

Implemented a new http mod to better http support and alias `fetch` and
`post` commands to `http get` and `http post` respectively.

# User-Facing Changes

Users will be able to use HTTP method via http command, for example
``` shell
> http get "https://www.example.com"
<!doctype html>
<html>

LazyRecord (#7619)
This is an attempt to implement a new `Value::LazyRecord` variant for
performance reasons.

`LazyRecord` is like a regular `Record`, but it's possible to access
individual columns without evaluating other columns. I've implemented
`LazyRecord` for the special `$nu` variable; accessing `$nu` is
relatively slow because of all the information in `scope`, and [`$nu`
accounts for about 2/3 of Nu's startup time on
Linux](https://github.com/nushell/nushell/issues/6677#issuecomment-1364618122).

### Benchmarks

I ran some benchmarks on my desktop (Linux, 12900K) and the results are
very pleasing.

Nu's time to start up and run a command (`cargo build --release;
hyperfine 'target/release/nu -c "echo \"Hello, world!\""' --shell=none
--warmup 10`) goes from **8.8ms to 3.2ms, about 2.8x faster**.

Tests are also much faster! Running `cargo nextest` (with our very slow
`proptest` tests disabled) goes from **7.2s to 4.4s (1.6x faster)**,
because most tests involve launching a new instance of Nu.

### Design (updated)

I've added a new `LazyRecord` trait and added a `Value` variant wrapping
those trait objects, much like `CustomValue`. `LazyRecord`
implementations must implement these 2 functions:

```rust
// All column names
fn column_names(&self) -> Vec<&'static str>;

// Get 1 specific column value
fn get_column_value(&self, column: &str) -> Result<Value, ShellError>;
 ```

### Serializability

`Value` variants must implement `Serializable` and `Deserializable`, which poses some problems because I want to use unserializable things like `EngineState` in `LazyRecord`s. To work around this, I basically lie to the type system:

1. Add `#[typetag::serde(tag = "type")]` to `LazyRecord` to make it serializable
2. Any unserializable fields in `LazyRecord` implementations get marked with `#[serde(skip)]`
3. At the point where a `LazyRecord` normally would get serialized and sent to a plugin, I instead collect it into a regular `Value::Record` (which can be serialized)

Check all user groups. (#7775)
Previously the group check was only for the current users gid, now we
check against all the users groups.


# Description

Currently when using the `cd` command to enter a directory there was
only a check against the current user id, and exact current group id,
meaning if a directory had a group permission and that group wasn't the
users group it was effectively ignored.

The fix simply implements a check through all the users current groups.

# User-Facing Changes

So the following command
```

```
> 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

  <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")),

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`.

Detailed message during core dumped (#7737)
# Description

In bash when a program crashes, it prints the reason for what happened:
```
$ ./division_by_zero
Floating point exception (core dumped)
$ ./segfault
Segmentation fault (core dumped)
```

Nushell always prints the same thing in this case:
```
> ./division_by_zero
nushell: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```

This PR adds more detailed error printing, like in bash:
```
> ./division_by_zero
Floating point exception: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```

I made this message format as an example:
```
Floating point exception: oops, process './division_by_zero' core dumped
```
Instead of `nushell:` it writes a meaningful message, but I can change
this format as per the suggestions.

I tested the change only on linux, but it should work on other unix
systems.

Disallow encode's silent conversion to HTML entities (and add -i/--ignore-errors flag to re-allow it) (#7738)
# Description

Closes #7514.

* For both `encode` and `decode`: add a special case allowing `utf16` as
a valid alias for `utf-16` (just as `utf-8` has `utf8`).
* For `encode` , make it an error when encodings_rs replaces characters
outside the given encoding with HTML entities
* For `encode` , add `-i`/`--ignore-errors` flag to bring back this
behaviour.

Note: `--ignore-errors` does NOT ignore the error for using a wrong
encoding label like `uft8`

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
```rust
Pipeline {
    elements: [
        Expression(None, Expression {
            expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),
            span: Span { start: 39041, end: 39044 },
            ty: Any, custom_completion: None 
        }),
        Redirection(Span { start: 39058, end: 39062 }, Stdout, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None }),
        Redirection(Span { start: 39058, end: 39062 }, Stderr, Expression { expr: String("err.txt"), span: Span { start: 39063, end: 39070 }, ty: String, custom_completion: None })] }
```

### Block after
```rust

    elements: [
        Expression(None, Expression {
            expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 38526, end: 38528 }, ty: String, custom_completion: None }, [], false),
            span: Span { start: 38525, end: 38528 },
            ty: Any,
            custom_completion: None 
        }),
        // new one! SeparateRedirection
        SeparateRedirection {
            out: (Span { start: 38529, end: 38533 }, Expression { expr: String("out.txt"), span: Span { start: 38534, end: 38541 }, ty: String, custom_completion: None }),
            err: (Span { start: 38542, end: 38546 }, Expression { expr: String("err.txt"), span: Span { start: 38547, end: 38554 }, ty: String, custom_completion: None })

Progress bar Implementation (#7661)
# Description

_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_

I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time

For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`

When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar 

![nu_pb01](https://user-images.githubusercontent.com/38369407/210298647-07ee55ea-e751-41b1-a84d-f72ec1f6e9e5.jpg)
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.

![nu_pb02](https://user-images.githubusercontent.com/38369407/210298698-1ef65f51-40cc-4481-83de-309cbd1049cb.jpg)

Please let me know If I need to make any changes and I will be happy to
do it.

# User-Facing Changes

A new flag (`--progress` `-p`) was added to the `save` command 
Examples:
```nu
fetch https://github.com/torvalds/linux/archive/refs/heads/master.zip | save --progress -f main.zip
fetch https://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso | save --progress -f main.zip

Revert "Primitives now use color closures..." (#7710)
This temporarily reverts commit c5639cd9fa
(PR https://github.com/nushell/nushell/pull/7650). See
[here](https://github.com/nushell/nushell/pull/7650#issuecomment-1375036213)
for details; the PR is accidentally adding ANSI escape codes to strings
piped to externals.

I think we should revert the PR because we're only 1-2 days away from a
release; reverting it will give us more time to land+test a proper fix
in the next release cycle.

move BufferedReader out of nu-command (#7697)
src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.

I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...

now that @rgwood  has landed benches I want
to start experimenting with benchmarks related
to the parser.

For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...

Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...

Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...

It will also enable other crates going forward to
use BufferedReader.  Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".

Make user parameter optional in fetch (#7680)
# Description

This commit makes the `user` parameter optional in the `fetch` command.
Previously when attempting to _only_ pass a `password`, the command
would ignore authentication. Now when a `user` is not supplied, but a
`password` is, an empty user is implied.

Before this PR, consider the following:
```nushell
fetch -password "mypassword" $url
```
This would result in the `password` parameter being ignored entirely.

Now, with changes made in this PR, consider the same code snippet as
above. The following HTTP header will be used:
```
Authentication: Basic <base64_encode(":{password}")>
```
Note that the `user` field is implied as empty if one is not supplied
when `password` is.

# User-Facing Changes

* `fetch` now supports `password`-only authentication, using an empty
`user` if one is not supplied.

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`

uniq and uniq-by optimization (#7477) (#7534)
# Description

Refactored the quadratic complexity on `uniq` to use a HashMap, as key I

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 input type was also wrong. Fixed.

Before:
```bash

Usage:
  > url 

Subcommands:
  url parse - Parses a url

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

Signatures:
  <string> | url -> <string>
```

After:
```bash
〉help url
Various commands for working with URLs

You must use one of the following subcommands. Using this command as-is will only produce this help message.

Search terms: network, parse

Usage:
  > url 

Subcommands:
  url parse - Parses a url

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

Signatures:

# User-Facing Changes

If you specify the `-m` flag, you get the "guessed at" mime type. The
guess is based on the file name and uses this crate
https://docs.rs/mime_guess/latest/mime_guess/ for the guessing.

Part of issue #7612 and and #7524

There's some debate on if the `mime-type` should be added to the `type`
column or if there should be a separate `mime` column. I tend to lean on
the side of `type` since it's technically a type and it's only in that
column if you ask it to be there. Also, I'd prefer to reuse a column
rather than having a list of sprawling columns. Also, as @KodiCraft
suggested, there is precedence as with `ls -d` where the summed size is
in the size column.

I could go either way and if someone wants to create a `mime` column,
we'd probably accept it.

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)

Further cleanup of Span::test_data usage + span fixes (#7595)
# Description

Inspired by #7592

For brevity use `Value::test_{string,int,float,bool}`

Includes fixes to commands that were abusing `Span::test_data` in their
implementation. Now the call span is used where possible or the explicit
`Span::unknonw` is used.

## Command fixes
- Fix abuse of `Span::test_data()` in `query_xml`
- Fix abuse of `Span::test_data()` in `term size`
- Fix abuse of `Span::test_data()` in `seq date`
- Fix two abuses of `Span::test_data` in `nu-cli`
- Change `Span::test_data` to `Span::unknown` in `keybindings listen`
- Add proper call span to `registry query`
- Fix span use in `nu_plugin_query`
- Fix span assignment in `select`
- Use `Span::unknown` instead of `test_data` in more places

## Other
- Use `Value::test_int`/`test_float()` consistently
- More `test_string` and `test_bool`
- Fix unused imports

Certain commands that operate on tables also work on bare records, but

I did not fix certain commands which, I feel, currently give unintended

Also corrected the wording of some stuff in headers.rs, and removed a
wrong comment in insert.rs.

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 config.filesize_format/config.filesize_metric conflict resolution consistent (#7410)
# Description

Currently, `filesize_format`/`filesize_metric` conflicts are resolved as
follows: if the `filesize_format` ends in "ib", then that overrides
`filesize_metric`, otherwise, `filesize_metric` overrides
`filesize_format`. This removes this difficult-to-predict asymmetric
behaviour, and makes it so that `filesize_metric` always overrides
`filesize_format`.

This also adds tests for `$env.config.filesize.format` and
`$env.config.filesize.metric` values.

REMINDER: `filesize_metric` means "increments of 1000", and refers to
KB-MB-GB-TB etc.

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

table: Check stream timeout on every item (#7509)
`table` handles slow `ListStream`s in a special way: every 100 items, it
checks whether 1 second has elapsed since the last table page, and if so
it outputs a new page with all the items in its buffer.

**I would like to remove the "every 100 items" condition and always
output whatever we have if a second has elapsed.** I think this will be
a better user experience for very slow streams.

As a motivating example, imagine tailing a log file and doing some
string parsing/projection on each line. The user will be really annoyed
if they have to wait for 100 lines to be written to the log before
seeing new results!

I did some quick performance measurements with Criterion, and the
elapsed-time check takes about 16ns on my machine (Linux, 12900k). I
think the performance impact of checking that for every item will be
negligible.

Patch after fix after fix 7380 (#7501)
> I'm not sure how i feel about that. I mean if there are a lot of
columns, it should probably have a max width so 1 column doesn't take
the entire width of your screen. Ideally it would work closely like
table worked before we migrated to tabled, as far as how column widths
were allocated.

I believe it still not completely matched.
*To be honest I am not against the #7446 approach.

The PR makes a switch between logics on a premise of `termwidth`.
So if `termwidth > 120` we start prioritizing amount of columns we can
show (We try to show as many columns as we can).
Otherwise we do what I've described in #7446 (We show the least columns
but with least truncation involvement).

In case it's OK,
I guess we could make the value configurable.

explore tweaks Round 1 (#7511)
A few small tweaks to the new `explore` command:

1. Rewrote the help text a bit.
    1. I think it's important to mention `:try` up front.
2. Removed the info about `:help foo` because it's currently supported
by very few subcommands
2. Make `exit_esc` default to true. I want to avoid people getting stuck
in `explore` like they get stuck in Vim
3. ~~Always show the help message ("For help type :help") on startup~~
1. The message is small+unobtrusive and I don't this is worth a
configuration item
4. Exit the information view when Escape is pressed
5. General typo+grammar cleanup

color_config now accepts closures as color values (#7141)
# Description

Closes #6909. You can now add closures to your `color_config` themes.
Whenever a value would be printed with `table`, the closure is run with
the value piped-in. The closure must return either a {fg,bg,attr} record
or a color name (`'light_red'` etc.). This returned style is used to
colour the value.

This is entirely backwards-compatible with existing config.nu files.

Example code excerpt:
```
let my_theme = {
    header: green_bold
    bool: { if $in { 'light_cyan' } else { 'light_red' } }
    int: purple_bold
    filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } }
    duration: purple_bold
    date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } }
    range: yellow_bold
    string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }
    nothing: white
```
Example output with this in effect:

Slightly important notes:

* Some color_config names, namely "separator", "empty" and "hints", pipe
in `null` instead of a value.
* Currently, doing anything non-trivial inside a closure has an
understandably big perf hit. I currently do not actually recommend
something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' }
}` for serious work, mainly because of the abundance of string-type data
in the world. Nevertheless, lesser-used types like "date" and "duration"
work well with this.
* I had to do some reorganisation in order to make it possible to call
`eval_block()` that late in table rendering. I invented a new struct
called "StyleComputer" which holds the engine_state and stack of the
initial `table` command (implicit or explicit).
* StyleComputer has a `compute()` method which takes a color_config name
and a nu value, and always returns the correct Style, so you don't have
to worry about A) the color_config value was set at all, B) whether it
was set to a closure or not, or C) which default style to use in those
cases.
* Currently, errors encountered during execution of the closures are
thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors
result in a huge perf hit when they are encountered. I think what should
be done is to assume something terrible happened to the user's config
and invalidate the StyleComputer for that `table` run, thus causing
subsequent output to just be Style::default().)
* More thorough tests are forthcoming - ran into some difficulty using
`nu!` to take an alternative config, and for some reason `let-env config
=` statements don't seem to work inside `nu!` pipelines(???)
* The default config.nu has not been updated to make use of this yet. Do
tell if you think I should incorporate that into this.

Remove unnecessary echo uses from examples (#7500)
`echo` tends to confuse new Nu users; they expect it to work like
`print` when it just passes a value to the next stage of the pipeline.

We haven't quite figured out what to do about `echo` in the long run,
but I think a good start is to remove `echo` from command examples where
it would be unnecessary and arguably unidiomatic.

Add helper method to check whether ctrl+c was pressed, adopt it (#7482)

bothering me that checking ctrl+c (something we want to do often) always

if let Some(ctrlc) = &engine_state.ctrlc {
     if ctrlc.load(Ordering::SeqCst) {
          ...
```
I added a helper method to cut that down to:

```rust
if nu_utils::ctrl_c::was_pressed(&engine_state.ctrlc) {
    ...

Fix streaming page missing newline (#7466)
Fixes #7342. `0..1000 | table` before this change:


![image](https://user-images.githubusercontent.com/26268125/207474492-dead4267-d828-4840-8da0-4edfda3e3916.png)

`0..1000 | table` after this change:


![image](https://user-images.githubusercontent.com/26268125/207474583-26633db0-46c5-4c30-8681-654855e7042b.png)

When piping data to `table`, pages were not getting a newline at the
end[^1]. This problem was uncovered and exacerbated by the new
`display_output` hook which implicitly piped _everything_ to `table`.

## The Fix

`PagingTableCreator` now adds a newline to each page instead of relying
on later code to do it.

## Tests

I spent a while trying to write a regression test for this behaviour but
I couldn't get the test to fail before my fix! I think the test
infrastructure does something special with newlines when it's checking
command output. I eventually ran out of steam trying to investigate
that, sorry.

[^1]: unless the pipe to table was the implicit one that's done when
there is no `display_output` hook set. That situation was still working
OK.

Revert "Pipeline operators: && and ||" (#7452)
Reverts nushell/nushell#7448

Some surprising behavior in how we do this. For example:

```
〉if (true || false) { print "yes!" } else { print "no!" }
no!
〉if (true or false) { print "yes!" } else { print "no!" }
yes!
```

This means for folks who are using the old `||`, they possibly get the
wrong answer once they upgrade. I don't think we can ship with that as
it will catch too many people by surprise and just make it easier to
write buggy code.

Pipeline operators: && and || (#7448)
# Description

We got some feedback from folks used to other shells that `try/catch`
isn't quite as convenient as things like `||`. This PR adds `&&` as a

## About change
In `eval_block`, all pipelines(or called statements?) result will be
printed except the last one, the last one is returned by `eval_block`
function.

So if we want to print the last statement in eval block, we just need to
print that value.

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.

make split row works like python and rust ways (#7413)

Fixes: #7389 

Make split row works more like python or rust, especially, when the
input string stars/ends with separator, append a empty string to result.
Here are examples:

python:
```python
In [6]: "\nasdf\nghi\n".split("\n")
Out[6]: ['', 'asdf', 'ghi', '']
```
rust:
```rust
fn main() {
    let x = "\nabc\ndef\n";
    let y = x.split("\n").collect::<Vec<&str>>();
    println!("{:?}", y);   // outputs: ["", "abc", "def", ""]

Reduced LOC by replacing several instances of Value::Int {}, Value::Float{}, Value::Bool {}, and Value::String {} with Value::int(), Value::float(), Value::boolean() and Value::string() (#7412)
# Description

While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
  val: a,
  span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

Add arbitrary base math log (#7409)
Adds new command `math log` that takes as a required positional argument
a base.

Specialized for `math log 2` and `math log 10` for better performance
and precision that matches the expectations there. This leads to
discontinuities in numerical error but should make a better trade-off
for common usecases.

Add OneOf shape to fix else (#7385)
# Description

fixes #7384 

This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

# User-Facing Changes

Improve empty pipelines (#7383)
# Description

This fix changes pipelines to allow them to actually be empty. Mapping
over empty pipelines gives empty pipelines. Empty pipelines immediately
return `None` when iterated.

fix semicolon doesn't work for some commands (#7373)
# Description

Fix semicolon working for the following commands which runs to failed:

1. into record (example: `into record; echo 'aa'`) -- the final aa
shouldn't be printed
2. save ( example: `touch a; chmod a-w a; echo 'aa' | save a; echo asdf`
) -- the final asdf shouldn't be printed
3. fetch ( example: `touch a; chmod a-w a; fetch https://www.google.com
-o a; echo asdf` ) -- the final asdf shouldn't be printed
4. registry_query (I don't have window machine, sorry for that I can't
demo for it)

I've reviewed most of built-in commands, and it seems that other

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.

Make SQLite queries cancellable (#7351)
This change makes SQLite queries (`open foo.db`, `open foo.db | query db
"select ..."`) cancellable using `ctrl+c`. Previously they were not
cancellable, which made it unpleasant to accidentally open a very large
database or run an unexpectedly slow query!

UX-wise there's not too much to show:

## Notes

I was hoping to make SQLite queries streamable as part of this work, but
I ran into 2 problems:
1. `rusqlite` lifetimes are nightmarishly complex and they make it hard
to create a `ListStream` iterator
2. The functions on Nu's `CustomValue` trait return `Value` not
`PipelineData` and so `CustomValue` implementations can't stream data
AFAICT.

Improve error message for illegal filenames on Windows (#7348)
`ls` can fail when a directory contains a file that violates [the
Windows file naming
conventions](https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions).
This PR tweaks the error message so we tell the user _which_ file caused
the problem.

Closes #7345.

Like Chris said in the linked issue, it would be even better if Nu could
just handle these naughty files like cmd.exe and pwsh do. If someone has
the time to dive into how PowerShell does this, that would be much
appreciated.

Overhaul schema command, remove database name (#7344)
This PR changes the `schema` command for viewing the schema of a SQLite
database file. It removes 1 level of nesting (intended to handle
multiple databases in the same connection) that I believe is
unnecessary.

### Before

![image](https://user-images.githubusercontent.com/26268125/205467643-05df0f64-bc8f-4135-9ff1-f978cc7a12bd.png)

## Rationale

A SQLite database connection can technically be associated with multiple
non-temporary databases using [the ATTACH DATABASE
command](https://www.sqlite.org/lang_attach.html). But it's not possible
to do that _in the context of Nushell_, and so I believe that there is
no benefit to displaying the schema as if there could be multiple
databases.

I initially raised this concern back in April, but we decided to keep
the database nesting because at the time we were still looking into more
generalized database functionality (i.e. not just SQLite). I believe
that rationale no longer applies.

Also, the existing code would not have worked correctly even if a
connection had multiple databases; for every database, it was looking up
tables without filtering them by database:

6295b20545/crates/nu-command/src/database/values/sqlite.rs (L104-L118)

## Future Work

I'd like to add information on views+triggers to the `schema` output.
I'm also working on making it possible to `ctrl+c` reading from a
database (which is turning into a massive yak shave).

Rename $env.config.explore_config to $env.config.explore (for consistency with $env.config.ls, $env.config.table etc.) (#7317)
# Description

* `$env.config.explore_config` renamed to `$env.config.explore`. This
follows the principle that config subrecords relating to single commands
(as this relates to `explore`) should be exactly named after the command
(see `ls`, `rm`, `table` etc.)
* In `into_config()`, moved the match arm relating to
`$env.config.explore` out of the "legacy options" section (which is
slated for removal in a later version).

Fix where -b flag (#7313)
# Description

The `where -b` flag was broken. The following now works:
```
let cond = {|x| $x.name !~ 'foo'}; ls | where -b $cond
```

This is just a quick fix. Ultimately, the `where` command shouldn't need
the flag and `where $cond` should work. The first step, however, is to
move `where` away from shape-directed parsing and make it a parser
keyword.

     # line_head_bottom: false,
   }
```

You can start without a pipeline and type `explore` and it'll give you a
few tips.

If you type `:help` you an see the help screen with some information on
what tui keybindings are available.

From the `:help` screen you can now hit `i` and that puts you in
`cursor` aka `inspection` mode and you can move the cursor left right up
down and it you put it on an area such as `[table 5 rows]` and hit the
enter key, you'll see something like this, which shows all the `:`
commands. If you hit `esc` it will take you to the previous screen.

If you then type `:try` you'll get this type of window where you can
type in the top portion and see results in the bottom.

The `:nu` command is interesting because you can type pipelines like
`:nu ls | sort-by type size` or another pipeline of your choosing such
as `:nu sys` and that will show the table that looks like this, which
we're calling "table mode".

If you hit the `t` key it will now transpose the view to look like this.

![image](https://user-images.githubusercontent.com/343840/205090948-a834d7f2-1713-4dfe-92fe-5432f287df3d.png)

In table mode or transposed table mode you can use the `i` key to
inspect any collapsed field like `{record 8 fields}`, `[table 16 rows]`,
`[list x]`, etc.

One of the original benefits was that when you're in a view that has a
lot of columns, `explore` gives you the ability to scroll left, right,
up, and down.

`explore` is also smart enough to know when you're in table mode versus
preview mode. If you do `open Cargo.toml | explore` you get this.

If you type `open --raw Cargo.toml | explore` you get this where you can
scroll left, right, up, down. This is called preview mode.

When you're in table mode, you can also type `:preview`. So, with `open
--raw Cargo.toml | explore`, if you type `:preview`, it will look like
this.
