* Fix parser expanding dots where it shouldn't
Previously, the parser would expand "a...b" as "a../..b". Now, >2 dots
are only expanded when the whole path component consists of dots (i.e.,
"..." expands to "../.." while "a...b" stays as it is).
* Respect OS separator when expanding >2 dots
"..." now expands to either "../.." or "..\..", based on the host OS.
Not all lite command's first part denotes a real command (for cases like sub commands that it's second lite part accounts for the command name). This is important so that we can refer to it's span correctly. Here we fix to include the command's name span correctly whether it's a command or sub command when reporting missing flag errors.
* Add first prototype of functionality to parse numbers in parantheses (). Needs testing and more wide-testing+integration
* Fix styling issue
* Try something else by copying existing matching code
* Fix formatting
* Fix the parser to accept numbers in paranthesis. Not really happy with the code, but let's see
* Refactor to only use once the parsing of strings into numbers
* Remove errors that are not used
* Fix formatting

* Move tests into own file
* Move data structs to own file
* Move functions parsing 1 Token (primitives) into own file
* Rename param_flag_list to signature
* Add tests
* Fix clippy lint
* Change imports to new lexer structure
* 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.
* Update meta.rs

* 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
