brainless

Transpile "python" programs into brainf*** ascii art

Installing / Compiling

Note: requires cabal-install

1. Clone repo
2. Open your terminal of choice
3. While in repository base (that's the folder with this file in it!), either:
   • Run cabal install to install the project to your system
   • Run cabal run . -- [ARGUMENTS] to run this project without installing

Usage

For more information, run brainless --help.

Commands

Only a small subset of python has been implemented:

• <varname> = <expression>
• print(<expression>)
• a + b, a - b, a * b, a // b, a % b for basic operations
• a + b for string concatenation. Note that creating strings longer than the specified --string-length (default: 64) is undefined behaviour.
• a >= b, a <= b, a < b, a >= b, a == b for numeric comparison. Also technically defined for string comparison, but there is an unresolved bug in this area.
• a and b, a or b, not a for boolean logic
• input(a) or input() to get a line of user input
• chr(a) to convert an integer into the corresponding character. ord(a) to get the character code of the start of a string.
• while <expression>: and if <expression>. Make sure to indent by exactly 4 spaces at this time. There is a bug related to nested while/if loops.

Todo

• Finish by the end of the hackathon
• Fix bugs to do with nested while loops and/or string comparison
• Add infix operators
• Expand available commands
• Optimise generated code / optimise compile times
• Optimise memory management
