9. Invoking Bison

The usual way to invoke Bison is as follows:

 
bison infile

Here infile is the grammar file name, which usually ends in `.y'. The parser file's name is made by replacing the `.y' with `.tab.c'. Thus, the `bison foo.y' filename yields `foo.tab.c', and the `bison hack/foo.y' filename yields `hack/foo.tab.c'. It's also possible, in case you are writing C++ code instead of C in your grammar file, to name it `foo.ypp' or `foo.y++'. Then, the output files will take an extension like the given one as input (respectively `foo.tab.cpp' and `foo.tab.c++'). This feature takes effect with all options that manipulate filenames like `-o' or `-d'.

For example :

 
bison -d infile.yxx
will produce `infile.tab.cxx' and `infile.tab.hxx', and

 
bison -d -o output.c++ infile.y
will produce `output.c++' and `outfile.h++'.

For compatibility with POSIX, the standard Bison distribution also contains a shell script called yacc that invokes Bison with the `-y' option.
