yacc

yacc [options] file

Given a file containing context-free grammar, convert file into tables for subsequent parsing and send output to y.tab.c. This command name stands for yet another compiler-compiler. See also lex and the Nutshell Handbook lex & yacc.

Options

-d

Generate y.tab.h, producing #define statements that relate yacc's token codes to the token names declared by the user.

-l

Exclude #line constructs from code produced in y.tab.c. (Use after debugging is complete.)

-Qc

Place version information about yacc in y.tab.c (if c = y) or suppress information (if c = n, the default).

-t

Compile runtime debugging code by default.

-v

Generate y.output, a file containing diagnostics and notes about the parsing tables.

-V

Print the version of yacc on standard error.
