cfgpp-bf-interpreter

Brainfuck interpreter written in SAR's Config+ language for Portal 2.

Usage

To run a brainfuck program:

• Place bf-interpreter.cfg in Portal 2/portal2/cfg. (or the equivalent folder for mods/p2common)
• Ensure SAR is loaded. (plugin_load sar)
• Initialise the interpreter with exec bf-interpreter ingame.
• Run the program with bf_exec <program>. Note that user input syntax , is not yet supported and will be skipped over in execution. Also note that programs greater than 247 characters long will be truncated, or 504 if the bf_exec is inside a .cfg that is exec'd. This is unavoidable with current technology.

You can modify the speed at which the program is executed by running svar_set __bf_delay <ticks> where each tick is 1/60 of a second. A delay of 0 will run the entire program immediately.
