Module: MdxTex::ToMarkdown::OrderedList

Defined in:
lib/mdx_tex/to_markdown/ordered_list.rb

Overview

Converts a Textile ordered list item to a Markdown ordered list item. Depth is derived from the leading-hash count minus base_list_depth (the smallest hash count seen anywhere in the document, detected by the coordinator). Markdown indents 2 spaces per depth level. The number is supplied by the coordinator, which maintains per-depth counters.

| Input (Textile) | base_list_depth | number | Output (Markdown) | |—————–|—————–|——–|——————-| | # item | 1 | 1 | 1. item | | # item | 1 | 5 | 5. item | | ## nested | 1 | 1 | 1. nested | | ## item | 2 | 1 | 1. item |

INDENT_SIZE =

PATTERN =

Matches a Textile ordered list line: optional leading whitespace, a run of hashes, a mandatory space, and at least one content character.

\A          start of line
\s*         tolerate leading whitespace (not preserved in the output)
(#+)        capture the run of hashes (depth indicator)
\s+         one or more whitespace chars
            (required: distinguishes a list marker from things like
            `#foo` which is not a Textile ordered list item)
(.+)        capture the item content
\z          end of line

/\A\s*(#+)\s+(.+)\z/.freeze
