Compiler for the lila programming language

#Lila compiler

Lila is a strongly typed, imperative programming language designed by me as part of a university project.

This compiler translates a lila source code file into x86 NASM Assembler. It then calls nasm to assemble the file and finally calls the GNU linker (ld) to link and generate a linux executable file. As a result, in order to test the compiler both nasm and ld must be installed and added to the system $PATH. Also, the compiler is written in python 2 and will not work under python 3 (although it should be very easy to get it working).

Each file is separated in the logical steps the compiler takes:

1. tokenizer.py uses the lexer from ply to define the tokens available in lila

2. parser.py similarly uses ply to parse the lila source code and builds a syntax tree

3. analyzer.py performs semantic analysis

4. codegen.py generates the actual assembler code

5. lila.py is the actual file that calls all other files and does the assembling and linking

Installation

Just do:

$ git clone https://github.com/TrustMeImAProgrammer/Lila-Compiler.git
$ cd Lila-Compiler

To compile a source file simply do:

python lila.py sourcecode.lila

After this an executable file called sourcecode will be generated if everything went well.

I've tried to make Lila's syntax very readable while taking a few ideas from C's and python's syntax. I'll upload a list of example lila files to run tests on and get an idea of lila's syntax.

##TODO

• While the parser accepts keywords to declare floating point variables, this functionality is still not implemented.
• I'm aware the way the compiler works is far from being optimal, I might add some optimizations in the future.
