lex

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

• Generate an analyser from a Lex file:

lex {{analyser.l}}

• Specify the output file:

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

• Compile a C file generated by Lex:

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