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 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.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
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
`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
