* Add new flags to r2 - -D : enable debugger mode for non native debuggers - -c cmd : execute a command before showing prompt * Initial import of the bfvm (brainfuck virtual machine) * Initial dummy implementation of the brainfuck debugger plugin - Needs to be integrated with bfvm to work * Added doc/brainfuck

Brainfuck support for r2
========================
Plugins for brainfuck:
* Implemented assembler support for asm.bf plugin * Added support for breakpoints in the brainfuck debugger - Fixed write delegate in io.bfdbg plugin - asm.bf is now compiled as static in core
2011-10-09 02:41:53 +00:00
- asm.bf - brainfuck assembler and disassembler
- debug.bf - debugger using bfvm
- anal.bf - code analysis for brainfuck
- bp.bf - breakpoints support (experimental)
* Add new flags to r2 - -D : enable debugger mode for non native debuggers - -c cmd : execute a command before showing prompt * Initial import of the bfvm (brainfuck virtual machine) * Initial dummy implementation of the brainfuck debugger plugin - Needs to be integrated with bfvm to work * Added doc/brainfuck

* Add make chlog target to genereate shlogs * Fully implement the asm.bf assembler and disassembler - Syntax fixed. disassembled code can be reassembled - Added support for misd instructions (multiple instruction single data) rasm2 -a bf 'add [ptr], 8;trap,64;nop;poke;'

The debugger creates virtual sections for code, data, screen and input.
TODO
----
- add support for comments, ignore invalid instructions as nops
* Implemented assembler support for asm.bf plugin * Added support for breakpoints in the brainfuck debugger - Fixed write delegate in io.bfdbg plugin - asm.bf is now compiled as static in core

- enhace io and debugger plugins to generate sections and set arch opts
* Add new flags to r2 - -D : enable debugger mode for non native debuggers - -c cmd : execute a command before showing prompt * Initial import of the bfvm (brainfuck virtual machine) * Initial dummy implementation of the brainfuck debugger plugin - Needs to be integrated with bfvm to work * Added doc/brainfuck
