BISON(1) User Commands BISON(1) 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 pre- fix 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 bi- son will follow your extension to name the output file (.cpp or .c++). For instance, a grammar description file named parse.yxx would produce the gen- erated parser in a file named parse.tab.cxx, instead of yacc's y.tab.c or old Bison version's parse.tab.c. This description of the options that can be given to bison is adapted from the node Invocation in the bison.texi manual, which should be taken as au- thoritative. Bison supports both traditional single-letter options and mnemonic long op- tion names. Long option names are indicated with -- instead of -. Abbre- viations 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 a deterministic LR or generalized LR (GLR) parser employing LALR(1), IELR(1), or canonical LR(1) parser tables. 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 and exit --print-datadir output directory containing skeletons and XSLT and exit -u, --update apply fixes to the source grammar file and exit -f, --feature[=FEATURES] activate miscellaneous features FEATURES is a list of comma separated words that can include: caret, diagnostics-show-caret show errors with carets fixit, diagnostics-parseable-fixits show machine-readable fixes syntax-only do not generate any file all all of the above none disable all of the above Diagnostics: -W, --warnings[=CATEGORY] report the warnings falling in CATEGORY --color[=WHEN] whether to colorize the diagnostics --style=FILE specify the CSS FILE for colorizer diagnostics Warning categories include: conflicts-sr S/R conflicts (enabled by default) conflicts-rr R/R conflicts (enabled by default) counterexamples, cex generate conflict counterexamples dangling-alias string aliases not attached to a symbol deprecated obsolete constructs empty-rule empty rules without %empty midrule-values unset or unused midrule values precedence useless precedence and associativity yacc incompatibilities with POSIX Yacc other all other warnings (enabled by default) all all the warnings except 'counterexamples', 'dangling-alias' and 'yacc' no-CATEGORY turn off warnings in CATEGORY none turn off all the warnings error[=CATEGORY] treat warnings as errors WHEN can be one of the following: always, yes colorize the output never, no don't colorize the output auto, tty colorize if the output device is a tty Tuning the Parser: -L, --language=LANGUAGE specify the output programming language -S, --skeleton=FILE specify the skeleton to use -t, --debug instrument the parser for tracing same as '-Dparse.trace' --locations enable location support -D, --define=NAME[=VALUE] similar to '%define NAME VALUE' -F, --force-define=NAME[=VALUE] override '%define NAME VALUE' -p, --name-prefix=PREFIX prepend PREFIX to the external symbols deprecated by '-Dapi.pre- fix={PREFIX}' -l, --no-lines don't generate '#line' directives -k, --token-table include a table of token names -y, --yacc emulate POSIX Yacc Output Files: -H, --header=[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 --html[=FILE] also output an HTML report of the automaton -x, --xml[=FILE] also output an XML report of the automaton -M, --file-prefix-map=OLD=NEW replace prefix OLD with NEW when writing file paths in output files THINGS is a list of comma separated words that can include: states describe the states itemsets complete the core item sets with their closure lookaheads explicitly associate lookahead tokens to items solved describe shift/reduce conflicts solving counterexamples, cex generate conflict counterexamples all include all the above information none disable the report AUTHOR Written by Robert Corbett and Richard Stallman.
