Module rustla::parser::state_machine::inline[−][src]

A submodule related to parsing blocks of text for inline elements.

Inline markup recognition rules

Inline markup start-strings and end-strings are only recognized if the following conditions are met:

  1. Inline markup start-strings must be immediately followed by non-whitespace.
  2. Inline markup end-strings must be immediately preceded by non-whitespace.
  3. The inline markup end-string must be separated by at least one character from the start-string.
  4. Both, inline markup start-string and end-string must not be preceded by an unescaped backslash (except for the end-string of inline literals). See Escaping Mechanism above for details.
  5. If an inline markup start-string is immediately preceded by one of the ASCII characters ’ “ < ( [ { or a similar non-ASCII character, it must not be followed by the corresponding closing character from ’ “ ) ] } > or a similar non-ASCII character. (For quotes, matching characters can be any of the quotation marks in international usage.)

If the configuration setting simple-inline-markup is False (default), additional conditions apply to the characters “around” the inline markup:

  1. Inline markup start-strings must start a text block or be immediately preceded by

    • whitespace,
    • one of the ASCII characters - : / ’ “ < ( [ {
    • or a similar non-ASCII punctuation character.

  2. Inline markup end-strings must end a text block or be immediately followed by

    • whitespace,
    • one of the ASCII characters - . , : ; ! ? \ / ’ “ ) ] } >
    • or a similar non-ASCII punctuation character.

Functions

citation_ref

Parses citation references.

footnote_ref

Parses footnote references.

inline_target

Parses inline reference targets. These do not actually create new nodes, but push new labels into the doctree’s inline target stack.

interpreted_text
paired_delimiter

Parses inline text elements that have identical opening and closing delimiters such as **strong emphasis** or ``literal_text``.

phrase_ref

Parses phrase references.

simple_ref

Parses simple hyperlink references.

substitution_ref

Parses inline subsitution references. Also adds hyperlink information to the reference, if the matched string ended with a __?.

text

This function is invoked when no other inline pattern matched. Eats up any consequent non-whitespace characters as a single word of “text”.

uri

Parses inline URIs. These are split into general URIs and standalone email addresses. These two are differentiate by whether the URI starts with a protocol scheme, such as https://.

whitespace

Parses inline whitespace.
