flex

Lexical analyser generator. Based on lex. Given the specification for a lexical analyser, generates C code implementing it.

  • Generate an analyser from a flex file:

flex {{analyser.l}}

  • Specify the output file:

flex --outfile {{analyser.c}} {{analyser.l}}

  • Compile a C file generated by flex:

cc {{path/to/lex.yy.c}} --output {{executable}}
