Writing Compiler Front-Ends for LLVM with Lua using Mewa

LLVM IR text representation makes it possible to write a compiler front-end without being bound to an API. We can map the source text to the text of LLVM IR and use the tools of the Clang compiler for further compilation steps. This opens the doors to implement compiler front-ends in different ways. Mewa tries to optimize the amount of code written. It targets single authors that would like to write a prototype of a non-trivial programming language fast, but at the expense of a structure supporting collaborative work. This makes it rather a tool for experiment than for building a product.
