Linux in a Nutshell, Third Edition

Name

bison

Synopsis

bison [options] file

Description

Given a file containing context-free grammar, convert into tables for subsequent parsing while sending output to file.c. This utility is both to a large extent compatible with yacc and named for it. All input files should use the suffix .y; output files will use the original prefix. All long options (those preceded by --) may instead be preceded by +.

Options

-b prefix, --file-prefix= prefix

Use prefix for all output files.

-d, --defines

Generate file.h, producing #define statements that relate bison’s token codes to the token names declared by the user.

-r, --raw

Use bison token numbers, not yacc-compatible translations, in file.h.

-k, --token-table

Include token names and values of YYNTOKENS, YYNNTS, YYNRULES, and YYNSTATES in file.c.

-l, --no-lines

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

-n, --no-parser

Suppress parser code in output, allowing only declarations. Assemble all translations into a switch statement body and print it to file.act.

-o file, --output-file= file

Output to file.

-p prefix, --name-prefix= prefix

Substitute prefix for yy in all external symbols.

-t, --debug

Compile runtime debugging code.

-v, --verbose

Verbose mode. Print diagnostics and notes about parsing tables to file.output.

-V, --version

Display version number.

-y, --yacc, --fixed-output-files

Duplicate yacc’s conventions for naming output files.
