| Usage: bison [OPTION]... FILE |
| 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) |
| 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 '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.prefix={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: |
| --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 |
| |
| 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 |
| all include all the above information |
| none disable the report |
