Enhancement: name lib and grammar generator with name of the grammar type #12

Closed vanhauser-thc closed 3 years ago

vanhauser-thc commented 3 years ago

when compiling for a grammar compiling new would overwrite an existing one. also from the lib name it is not clear for which grammar it is.

proposal: simply name the resulting grammar generator and lib with the grammar type, e.g. libgrammarmutator-json.so

I was thinking about this.

What about appending the grammar file name to the generated library? It looks a bit long. For example:

Grammar file: json_grammar.json
Generated library: libgrammarmutator_json_grammar.so

Or let the user specify a short name, so the name of the generated library can be shorter. Otherwise, we can fall back to the default naming, by appending the grammar file name to the library name.

Updated the building scripts to append a suffix to the grammar mutator lib and grammar_generator.

Please take a look at the latest commits in dev branch

I made a few changes, e.g. renaming to lowercase letter and removing everything after _.- to keep the name short. also made it a make option.

additionally I updated the documentation.

a few other things that could be done:

rename all files to lowercase
the RNG parameter for the grammar-generator could be made option and moved to the last position (and then e.g. time() being used as seed)

but I leave that decision to you.
