Brainfuck support for r2
|
|
========================
|
|
|
|
Plugins for brainfuck:
|
|
- asm.bf - brainfuck assembler and disassembler
|
|
- debug.bf - debugger using bfvm
|
|
- anal.bf - code analysis for brainfuck
|
|
- bp.bf - breakpoints support (experimental)
|
|
|
|
To debug a brainfuck program:
|
|
|
|
$ r2 -D bf bfdbg:///tmp/bf
|
|
|
|
> dc # continue
|
|
> x@scr # show screen buffer contents
|
|
|
|
The debugger creates virtual sections for code, data, screen and input.

- add support for comments, ignore invalid instructions as nops
|
|
- enhace io and debugger plugins to generate sections and set arch opts
