ShivyC

(self-promotion) I've created an open source C compiler written in Python (https://github.com/ShivamSarodia/ShivyC). I've learned a ton building it out so far, and I've found compiler design to be a great exercise in software engineering and learning Python since managing the complexity of a compiler is nontrivial. If you're interested in contributing, a good place to start is by tackling any of the issues marked as "good first issue".

It looks like that's what it is doing: https://github.com/ShivamSarodia/ShivyC/blob/156a71bce7f340d... The exceptions seem to be how it signals failure if the token doesn't match, but they aren't being used for unbounded lookahead.

So, is it issue? If so, please, report it for developer on Github[0] Or you know how to fix it? Then just pull[1] it to 'master' ;-) [0] https://github.com/ShivamSarodia/ShivyC/issues [1] https://github.com/ShivamSarodia/ShivyC/pulls

The parser has a somewhat unusual structure: https://github.com/ShivamSarodia/ShivyC/blob/master/shivyc/p... It's been a while since I've had to use the phrase "exception-oriented programming", but it fits that code well. While that might be a useful or even necessary pattern to parse something like C++ which can have almost unbounded ambiguities, AFAIK C can be parsed solely by branching on the next token in the stream except for one tiny case (typedefs).
