Posted May 28, 2015. It is possible to convert a part of a code in C for.lua? Share on other sites. ZeroBrane Studio provides a way to translate its interface elements (menus and captions) and messages to a different language. Create i18n/ll-cc.lua file for your language-country. The name of the file (ll-cc.lua) has two segments: ll (mandatory) – two letter language code; cc (optional) – two letter country code. Convert the lua files to C# code, where you want to work with them extensively, or you just want some code that does similar things than the original code. For the first type of conversion the answer is that it is quite hard, but not impossible. .

If you want this in a general sense, see David Given's clue [1,2], but
it's said to be experimental, and I doubt your result will be pretty.
This might be analogous to what Alchemy/LLVM does [5].
I have found that C code can be translated into Lua code in a mostly
mechanical way if want to preserve structure over efficiency. Even
something like a pointer into a C array can be translated into an
index into a Lua table array. That was the case with Lua's lstrlib.c
translated into Lua [3], and it appears also with Yueliang [4]. You
can stumble with things like 'continue' statements, which Lua doesn't
directly support, so you may need to do some pre-translation
reworking.

Lua code translating Brainfuck to C:

This script reads Brainfuck code from stdin and writescorresponding C code to stdout.

Let us compare the performance of code generated by the scriptwith Brainfuck interpreter beef and Brainfsck JITcompiler from DynASM tutorial.

Brainfuck to C translator

Translate Brainfuck code to C using the translator:

Compile generated C code:

Run the program:

Add option -O3 to enable more optimizations:

Brainfuck interpreter beef

Brainfuck JIT compiler

The Brainfuck JIT compiler can be found in the DynASMtutorial.

Build the Brainfuck JIT compiler:

Run the program:

Conclusions

The JIT compiler’s performance of Brainfuck code executionis comparable to the performance of C code generated fromBrainfuck code with -O3 optimizations enabled. The time ofexecution of gcc -O3 (4.7 seconds) added to the time ofexecution of compiled C code (1.6 seconds) exceeds the time ofexecution of JIT compiler (2.7 seconds).

Lua Function Call

Lua2cpp

Obvious advantage of JIT compiler is that it doesn’t require Ccompiler to execute Brainfuck code. Same JIT compiler binarycan execute any Brainfuck code while C compiler is needed eachtime to compile a C code translated from a Brainfuck code usingthe translator.

DynASM project is great!

Time of execution was measured onIntel(R) Core(TM) i5-3317U CPU @ 1.70GHz.
