NAME bison - GNU Project parser generator (yacc replacement)
SYNOPSIS bison [OPTION]... FILE
DESCRIPTION Bison is a parser generator in the style of yacc(1). It should be upwardly compatible with input files designed for yacc.
Input files should follow the yacc convention of ending in .y. Unlike yacc, the generated files do not have fixed names, but instead use the prefix of the input file. Moreover, if you need to put C++ code in the input file, you can end his name by a C++-like extension (.ypp or .y++), then bison will follow your extension to name the output file (.cpp or .c++). For instance, a grammar description file named parse.yxx would produce the generated parser in a file named parse.tab.cxx, instead of yacc s y.tab.c or old Bison versions parse.tab.c.
This description of the options that can be given to bison is adapted from the node Invocation in the bison.texinfo manual, which should be taken as authoritative.
Bison supports both traditional single-letter options and mnemonic long option names. Long option names are indicated with -- instead of -. Abbreviations for option names are allowed as long as they are unique. When a long option takes an argument, like --file-prefix, connect the option name and the argument with =.
Generate LALR(1) and GLR parsers.
Mandatory arguments to long options are mandatory for short options too. The same is true for optional arguments.
Operation modes: -h, --help display this help and exit
-V, --version output version information and exit
--print-localedir output directory containing locale-dependent data
--print-datadir output directory containing skeletons and XSLT
-y, --yacc emulate POSIX Yacc
-W, --warnings=[CATEGORY] report the warnings falling in CATEGORY
Parser: -L, --language=LANGUAGE specify the output programming language (this is an experimental feature)
-S, --skeleton=FILE specify the skeleton to use
-t, --debug instrument the parser for debugging
--locations enable locations computation
-p, --name-prefix=PREFIX prepend PREFIX to the external symbols
-l, --no-lines dont generate #line directives
-k, --token-table include a table of token names
Output: --defines[=FILE] also produce a header file
-d likewise but cannot specify FILE (for POSIX Yacc)
-r, --report=THINGS also produce details on the automaton
--report-file=FILE write report to FILE
-v, --verbose same as --report=state
-b, --file-prefix=PREFIX specify a PREFIX for output files
-o, --output=FILE leave output to FILE
-g, --graph[=FILE] also output a graph of the automaton
-x, --xml[=FILE] also output an XML report of the automaton (the XML schema is experimental)
Warning categories include: midrule-values unset or unused midrule values
yacc incompatibilities with POSIX YACC
all all the warnings
no-CATEGORY turn off warnings in CATEGORY
none turn off all the warnings
error treat warnings as errors
THINGS is a list of comma separated words that can include: state describe the states
itemset complete the core item sets with their closure
lookahead explicitly associate lookahead tokens to items
solved describe shift/reduce conflicts solving
all include all the above information
none disable the report
