  1. /*
  2. * The code below can be used to make a Lua core that does not contain the
  3. * parsing modules (lcode, llex, lparser), which represent 35% of the total core.
  4. * You'll only be able to load binary files and strings, precompiled with luac.
  5. * (Of course, you'll have to build luac with the original parsing modules!)
  6. *
  7. * To use this module, simply compile it ("make noparser" does that) and list
  8. * its object file before the Lua libraries. The linker should then not load
  9. * the parsing modules. To try it, do "make luab".
  10. *
  11. * If you also want to avoid the dump module (ldump.o), define NODUMP.
  12. * #define NODUMP
