Expand description

Parse the string into a series of Tokens.

VERSION controls the version of the format description that is being parsed. Currently, this must be 1 or 2.

  • When VERSION is 1, [[ is the only escape sequence, resulting in a literal [.
  • When VERSION is 2, all escape sequences begin with \. The only characters that may currently follow are \, [, and ], all of which result in the literal character. All other characters result in a lex error.
