Overview

Constant Summary collapse

FENCED_CODEBLOCK_MATCH =

GFM fenced code blocks, extended to allow spaces in the info string (e.g. ```c hlines=2). The GFM regex restricts the info string to a single non-whitespace token, which causes kramdown to miss blocks whose info string contains a space, leading to false positives inside them. Capture groups match GFM's: 1=fence, 2=fence-char, 3=full-info, 4=first-word, 5=content.

/^ {0,3}(([~`]){3,})\s*?((\S+?)[^\n]*)?\n(.*?)^ {0,3}\1\2*\s*?\n/m
PARAGRAPH_END =

End paragraphs when a fenced code block starts, matching GFM behavior. Without this, fenced code blocks without a preceding blank line are swallowed into the paragraph.

Regexp.union(
  Kramdown::Parser::Kramdown::PARAGRAPH_END,
  Kramdown::Parser::GFM::FENCED_CODEBLOCK_START,
)
