lark-formatter
==============
Simple attempt at a lark-parser grammar formatter, using Lark to lex the
grammar.
Installation
------------
Requires:
* Python 3.7+
* lark-parser
```bash
$ pip install .
```
Usage
-----
```bash
$ lark-formatter input_grammar.lark
$ cat input_grammar.lark | lark-formatter
```
Or in vim, to format part of a buffer, make a visual selection and then:
```
:!lark-format
```
(vim will automatically insert ``:'<,'>`` at the front, indicating the visual
selection region)
Notes
-----
* Likely will not work on everything
* No guarantees it won't mess up your grammar. Make sure it's
version-controlled first!
* ``->`` aliases are not aligned
* Spacing between comments and sections could use work
* ``check`` tool probably isn't good enough yet
