BrainF*ck Runtime in C, just a fun little project to learn C with. Might turn this into my own esolang later.

bf-runtime's Issues

Bug with nested loops

When the program encounters a closing bracket (']'), from what I understood, it sets program->current to the last opening bracket, which causes problems when you have nested loops. This can be fixed implementing the following:

• Create an char** array which is your stack
• Every time you encounter a [, loop through the entire program (to the right), and with each '[' you encounter, add its position into the stack, for each ']' you encounter, remove the last position from the stack. When you encounter ']' that removes the last element from the stack, that is the corresponding bracket
• Do the same thing in reverse every time you encounter a ].

I don't know if this is the most efficient way to do this, but it works, and that's enough for me

If you want an example just look at my implementation.
