In lua, is it possible to serialize functions (without upvalues) and store them WITHOUT USING LOADSTRING ?
You can serialize and store them without
loadstringat all – usestring.dump. You will only needloadstringif you want to deserealize them back.If you need it to reuse actual function later, (and not for some other simple purpose, like comparing), you will still need access to at least string version of
loadstring, because that’s the only facility that allows you to evaluate Lua source on the fly.If you have it, you may either try:
1) If you have access, modify Lua engine itself to save source code of function definition somewhere.
2) Write Lua bytecode to Lua source converter in Lua. With Lua’s simple VM it is not as hard task as it may sound.
If you have absolutely no access to
loadstringat all, you can try to write Lua VM in Lua. That’d be harder task than a simple converter, but still pretty doable.
