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 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 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.
