libphutil Technical Documentation (Lexers)

Lexer for a simple type grammar. See PhutilTypeSpec for a description.

Tasks

Lexer Implementation

Lexer Rules

  • protected function getRules() — Process, normalize, and validate the raw lexer rules.

Lexer Tokens

  • public function getTokens($input, $initial_state) — Lex an input string into tokens.

Other Methods

  • public function mergeTokens($tokens) — Merge adjacent tokens of the same type. For example, if a comment is tokenized as <"//", "comment">, this method will merge the two tokens into a single combined token.
  • public function getLexerState()
