Before, ps would not insert a value if the process didn't have a parent.
Now, ps will insert an empty cell. This caused broken tables as some
rows didn't have all the columns.
* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).
* Further clean up the lexer
- Consolidate the logic of the various token builders into a single type
- Improve and clean up the event-driven BlockParser
- Clean up comment parsing. Comments now contain their original leading
whitespace as well as trailing whitespace, and know how to move some
leading whitespace back into the body based on how the lexer decides
to dedent the comments. This preserves the original whitespace
information while still making it straight-forward to eliminate leading
whitespace in help comments.

* Add possibility to declare optional parameters and switch flags
With this commit applied it is now possible to specify optional parameters and flags
as switches. This PR **only** makes guarantees about **parsing** optional flags and
switches correctly. This PR **does not guarantee flawless functionality** of
optional parameters / switches within scripts.
functionality within scripts. Example:
test.nu
```shell
def my_command [
opt_param?
opt_param2?: int
--switch
] {echo hi nushell}
```
```shell
> source test.nu
> my_command -h
───┬─────────
0 │ hi
1 │ nushell
───┴─────────
Usage:
> my_command <mandatory_param> (opt_param) (opt_param2) {flags}
Parameters:
<mandatory_param>
(opt_param)
(opt_param2)
Flags:
-h, --help: Display this help message
--switch
--opt_flag <any>
```
* Update def docs
* Add rest arg to def
This commit applied adds the ability to define the rest parameter of a def
command. It does not implement the functionality to expand the rest argument in
a user defined def function.
The rest argument has to be exactly worded "...rest".
Example after this PR is applied:
file test.nu
```shell
def my_command [
...rest:int # My rest arg
] {
echo 1 2 3
}
```
```shell
> source test.nu
> my_command -h
Usage:
> my_command ...args {flags}
Parameters:
...args: My rest arg
Flags:
-h, --help: Display this help message
```

Extend the optional features to nu-command

* Put parse_definition related funcs into own module
* Add failing lexer test
* Implement Parsing of definition signature
This commit applied changes how the signature of a function is parsed. Before
there was a little bit of "quick-and-dirty" string-matching/parsing involved.
Now, a signature is a little bit more properly parsed.
The grammar of a definition signature understood by these parsing-functions is
as follows:
`[ (parameter | flag | <eol>)* ]`
where
parameter is:
`name (<:> type)? (<,> | <eol> | (#Comment <eol>))?`
flag is:
`--name (-shortform)? (<:> type)? (<,> | <eol> | (#Comment <eol>))?`
(Note: After the last item no <,> has to come.)
Note: It is now possible to pass comments to flags and parameters
Example:
[
d:int # The required d parameter
--x (-x):string # The all powerful x flag
--y (-y):int # The accompanying y flag
]
(Sadly there seems to be a bug (Or is this expected behaviour?) in the lexer, because of which `--x(-x)` would
be treated as one baseline token and is therefore not correctly recognized as 2. For
now a space has to be inserted)
During the implementation of the module, 2 question arose:
Should flag/parameter names be allowed to be type names?
Example case:
```shell
def f [ string ] { echo $string }
```
Currently an error is thrown
* Fix clippy lints
* Remove wrong comment
* Add spacing
* Add Cargo.lock
* move basic_shell_manager to nu-engine
* move basic_evaluation_context to nu-engine
* fix failing test in feature which commands/classified/external.rs
We split off the evaluation engine part of nu-cli into its own crate. This helps improve build times for nu-cli by 17% in my tests. It also helps us see a bit better what's the core engine portion vs the part specific to the interactive CLI piece.
There's more than can be done here, but I think it's a good start in the right direction.
* Obay precedence rules in which; Fix#2875
Before which did not obay the precedence of alias before def commands.
Furthermore, `which -a echo` would only report either an alias or a def command or an
internal command with the provided name. Not all.
With this commit applied its fixed :)
Example:
```shell
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> def echo [] {^echo hi}
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo
hi
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo
───┬──────┬──────────────────────────┬─────────
# │ arg │ path │ builtin
───┼──────┼──────────────────────────┼─────────
0 │ echo │ Nushell custom command │ No
1 │ echo │ Nushell built-in command │ Yes
2 │ echo │ /usr/bin/echo │ No
───┴──────┴──────────────────────────┴─────────
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> alias echo = ^echo hi there
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo
hi there
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo
───┬──────┬──────────────────────────┬─────────
# │ arg │ path │ builtin
───┼──────┼──────────────────────────┼─────────
0 │ echo │ Nushell alias │ No
1 │ echo │ Nushell custom command │ No
2 │ echo │ Nushell built-in command │ Yes
3 │ echo │ /usr/bin/echo │ No
───┴──────┴──────────────────────────┴─────────
```
* Fix clippy lint
* Fix vec always Some even if empty
This commit applied adds comments preceding a command to the LiteCommands new
field `comments`.
This can be usefull for example when defining a function with `def`. Nushell
could pick up the comments and display them when the user types `help my_def_func`.
Example
```shell
def my_echo [arg] { echo $arg }
```
The LiteCommand def will now contain the comments `My echo` and `It's much
better :)`.
The comment is not associated with the next command if there is a (or multiple) newline
between them.
Example
```shell
echo 42
```
This new functionality is similar to DocStrings. One might introduce a special
notation for such DocStrings, so that the parser can differentiate better
between discardable comments and usefull documentation.
