Usage: bison [OPTION]... FILE Generate a deterministic LR or generalized LR (GLR) parser employing LALR(1), IELR(1), or canonical LR(1) parser tables. IELR(1) and canonical LR(1) support is experimental. 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 -f, --feature[=FEATURE] activate miscellaneous features 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.prefix=PREFIX' -l, --no-lines don't 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 'conflicts-sr' S/R conflicts (enabled by default) 'conflicts-rr' R/R conflicts (enabled by default) 'deprecated' obsolete constructs 'empty-rule' empty rules without %empty 'precedence' useless precedence and associativity 'other' all other warnings (enabled by default) 'all' all the warnings except 'yacc' 'no-CATEGORY' turn off warnings in CATEGORY 'none' turn off all the warnings 'error[=CATEGORY]' 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 FEATURE is a list of comma separated words that can include: 'caret' show errors with carets 'all' all of the above 'none' disable all of the above Report bugs to <bug-bison@gnu.org>.
