Adjusting Markdown syntax, first list item falls back to list-paragraph

[sbcgua]

Hi There !

I want to adjust the Markdown syntax so that it recognize completed “TODO” items. I consider the following as such:

- this is normal list item
+ this is completed (should be grey)
- [x] this one is also comleted

Here is the syntax I came up with after consulting with chatgpt and syntax docs

name: MarkdownWithTodo
scope: text.html.markdown.withTodo
version: 2
hidden: false

extends: Packages/Markdown/Markdown.sublime-syntax

contexts:
  main:
    - match: ''
      set: markdown

  list-block-common:
    - meta_prepend: true
    - include: todo-list-items

  todo-list-items:
    # Case 1: + bullet, optional [x]/[X] checked checkbox
    - match: '([ \t]*)([+])((?:[ ](\[)([ xX])(\]))?)\s'
      captures:
        1: markup.list.unnumbered.markdown
        2: markup.list.unnumbered.bullet.plus.markdown punctuation.definition.list_item.markdown
        3: markup.list.unnumbered.markdown
        4: markup.checkbox.begin.markdown-gfm punctuation.definition.checkbox.begin.markdown-gfm
        5: markup.checkbox.mark.checked.markdown-gfm
        6: markup.checkbox.end.markdown-gfm punctuation.definition.checkbox.end.markdown-gfm
      push: todo-list-item-body

    # Case 2: Any bullet with checked checkbox (e.g. - [x])
    - match: '([ \t]*)([*-])([ ](\[)([xX])(\]))\s'
      captures:
        1: markup.list.unnumbered.markdown
        2: markup.list.unnumbered.bullet.markdown punctuation.definition.list_item.markdown
        3: markup.list.unnumbered.markdown
        4: markup.checkbox.begin.markdown-gfm punctuation.definition.checkbox.begin.markdown-gfm
        5: markup.checkbox.mark.checked.markdown-gfm
        6: markup.checkbox.end.markdown-gfm punctuation.definition.checkbox.end.markdown-gfm
      push: todo-list-item-body

  todo-list-item-body:
    - meta_content_scope: markup.list.todo-item.body.complete
    - include: todo-list-item-end

  todo-list-item-end:
    - match: '$'
      pop: true

And it works (the color scheme for markup.list.todo-item.body.complete is also present, just assume it works). But the problem is that it does not capture the first item in each list. The first item somehow falls back to list-pagagraph for some reason. Also it does not capture the list which starts without indentation (which is not super critical but I don’t understand the reason). Here is an example:

Would appreciate any hint. I just not understand. In the “Not captured as well” it enters the unordered-list and then goes to the list-paragraph although the list-block-common rule is above.

P.S. Version: 4169

I believe the first item not being captured is due to the list-blocks context doing the matching for the first item which begins a list block, so your list-block-common context doesn’t get involved. Probably you would need to add your changes to list-blocks also.

Also note list items do NOT end at the end of a line. Each item is a container for all sorts of normal content: headings, paragrphs, fenced code blocks, blockquotes etc. It is the next item or less indended heading, paragraph, code block … which terminates an item.
