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
parse.tab.cxx, instead of yacc's y.tab.c or old Bison version's
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 a deterministic LR or generalized LR (GLR) parser employing
LALR(1), IELR(1), or canonical LR(1) parser tables. IELR(1) and canon-
ical LR(1) support is experimental.
Mandatory arguments to long options are mandatory for short options
too. The same is true for optional arguments.
