lua-doc-parser

This is a Python script that will generate Markdown documentation from Lua source code.
It parses any Lua files in the current directory for any multi-line comment blocks and sequentially adds them to a markdown file based on the "header" of the comment block.

Example:

--[[ Header:method
Hello world!
--]]

This will create the following markup in a file named Header.md:

### Header:method

Hello world!

Header and method can be anything you want, but has to be separated by a colon (:) or a period (.).
The "magic" method name "header" can be used to force a block to appear on the top of the document as a header for the file, e.g:

--[[ MyObject:foo(_bar_)
This is a method `foo`, which takes argument `bar`.
--]]
--[[ MyObject:header
This will be at the **top** of the [MyObject](MyObject) document!  
Methods:
- [foo(_bar_)](MyObject#myobjectfoobar)
--]]

As you can see, any markdown notation is allowed inside the block.

Indentation is limited to tabs for the blocks, and any indendation inside the blocks is limited to spaces. This is to allow code snippets in documentation in-line in functions to parse correctly.

Usage

usage: parse.py [-h] [-o OUTPUT_DIR] [-b SEPARATOR] [-s HEADER_SIZE]

optional arguments:
  -h, --help      show this help message and exit
  -o OUTPUT_DIR   output directory (default: "docs")
  -b SEPARATOR    block separator (default: "***")
  -s HEADER_SIZE  header size (default: 3)

GitHub Action

This is an example workflow that will do the following:

• checkout the project and its wiki
• use this script as an action, outputting to the wiki directory
• commit and push the changes of the wiki directory

name: Generate documentation
on: push

jobs:
  docs:
    runs-on: ubuntu-latest
    steps:
      - name: Clone project
        uses: actions/checkout@v2

        with:
