       bison - GNU Project parser generator (yacc replacement)


       bison [OPTION]... FILE


       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, instead of yacc's or old Bison

       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 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 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

              output directory containing locale-dependent data

              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

       -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'

              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

              also produce a header file

       -d     likewise but cannot specify FILE (for POSIX Yacc)

       -r, --report=THINGS
              also produce details on the automaton

              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:
              unset or unused midrule values

       'yacc' incompatibilities with POSIX Yacc

              S/R conflicts (enabled by default)

              R/R conflicts (enabled by default)

              obsolete constructs

              empty rules without %empty

              useless precedence and associativity

              all other warnings (enabled by default)

       'all'  all the warnings except 'yacc'

              turn off warnings in CATEGORY

       'none' turn off all the warnings

              treat warnings as errors

   THINGS is a list of comma separated words that can include:
              describe the states

              complete the core item sets with their closure

              explicitly associate lookahead tokens to items

              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:
              show errors with carets

       'all'  all of the above

       'none' disable all of the above
