An interpreter for my Brainfuck-equivalent language, SpamFuck.
All of the commands are ingredients from Monty Python Spam Sketch meals
| Command | Brainfuck equivalent |
|---|---|
| spam | + |
| egg | - |
| sausage | < |
| bacon | > |
| tomato | , |
| bakedbeans | . |
| shallots | [ |
| aubergines | ] |
- The commands are case-sensitive, all lower case.
- Anything that is not a full formed command will be ignored. (So add some comments, just don't say spam!)
- No, you cannot have a space in bakedbeans.
Yeah yeah, the code is a mess, maybe I'll get around to cleaning it up a bit and making an AST type thing, idk. I haven't thoroughly debugged it but I'm fairly confident in it, I got a find and replace'd transpiled version of mitxela's bf tic tac toe ai working just fine in it, along with some Hello World's. I got all the issues I noticed hammered out (misreporting line numbers, not finding closing brackets) but if you find anything feel free to open an issue and I'll give it a fix!
While writing this interpreter, I ran into this weird issue on uh... g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0 <- this version of MinGW g++ where if there was a newline in a file std::ifstream's .tellg() would report num-of-newlines ahead of where it should. Except when you haven't read any characters in, then it reports 0 as usual. Also, if you .seekg() back to this over-reported number you end up at that over-reported point, so ahead of where you were when you .tellg()'d. Once you reach the newlines it starts syncing back up though. This issue (at least I think it's an issue, maybe I just don't understand the intended behaviors?) meant that I had to reinstall Visual Studio gasp to get MSVC, where it was working as I expected. Honestly I prefer Visual Studio's C++ integration over VSCode's.
If you are wondered about any implementation details like how many cells there are or how it treats EOF, check my brainfuck interpreter, under the hood it's the same thing.
As long as the commands are the same, you're good to go! I got my info about how brainfuck works from here
