Module: Coradoc::AsciiDoc::TypographicQuotes

Defined in:
lib/coradoc/asciidoc/typographic_quotes.rb

Overview

Single source of truth for AsciiDoc's typographic quote substitution.

Asciidoctor replaces four 2-char patterns with the corresponding Unicode curly quotes. Both the parser (to recognise the patterns) and the transformer (to emit the Unicode chars) reference this module — the mapping lives here, not on either consumer, so the parser/transformer seam stays clean.

The patterns MUST be recognised before monospace_constrained in the inline alternation, otherwise the lone backtick in <code>&quot;</code> or `"`` fires monospace and the surrounding quote collapses to straight ASCII quotes wrapped around a spurious code span.

PATTERN_TO_CHAR = 
{
  '"`' => '“',  # U+201C left double
  '`"' => '”',  # U+201D right double
  "'`" => '‘',  # U+2018 left single
  "`'" => '’'   # U+2019 right single
}.freeze
PATTERNS =

All four 2-char patterns, suitable for building a Parslet alternation.

Returns:

  • (Array<String>) 
PATTERN_TO_CHAR.keys.freeze
