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