This is simply yet another optimizing Brainfuck compiler written in Python. It features a lot of naïve optimizations and messy code :)
The interpreter part was done for Python college class at [FIT ČVUT] (http://fit.cvut.cz) by [Jiří Znamenáček] (http://ookami.cz)
The compile/optimize part was created whenever I was feeling bored at home with sometimes few years inbetween, hence the duplicated and messy code :)
- regular BF code, wrapped memory (by default 8 bit, can be changed in code)
- brainloller and braincopter (BF embedded into image file) - only uncompressed PNG supported
- passes most of [compiler tests] (http://www.hevanet.com/cristofd/brainfuck/tests.b)
- Python (default, input on Windows) (slow, unlimited memory)
- C (full support) (fastest when compiled, 30k cells as per original spec)
- PHP (no input support) (PHP 5 slower than Python 3.5, PHP 7 faster)
- Merging of consecutive operations
- Move, multiply and reset transformed into single operation
- Dead code elimination
- Value and pointer tracking when code is not too complicated
- Can simplify
[Hello world!] (http://esoteric.sange.fi/brainfuck/bf-source/prog/) programs
into
print ("Hello world!")
Always creates pybf.py file right inside src dir, so make sure it's
writable.
standard brainfuck files:
python readbf.py /path/to/file
brainloller:
python readpng.py loller /path/to/file
braincopter:
python readpng.py copter /path/to/file
silent png (no progress info):
python readpng.py loller|copter /path/to/file q
run last compiled file:
python pybf.py
- Feature parity on all language templates:
- universal input in Python
- input in PHP
- unlimited memory in C
- Code cleanup
- More optimizations if I find any
- [esolangs] (http://esolangs.org/wiki/Category:Brainfuck)
- [esotope-bfc] (http://code.google.com/p/esotope-bfc/) probably the most optimizing brainfuck compiler I found, also in Python
