[1:02:52][@paulsm1th][It seems like you are doing recursive descent parsing. Is that how you would describe it?]
[1:03:35][Blackboard: Recursive Descent Parser]
[1:05:04][simple_preprocessor.cpp: Introduce a more recursive example of ParseMember]
[1:09:17][@Pseudonym73][Can you please satisfy my C standard anal retention by accepting 'v' and 'f' as whitespace?]
[1:10:10][@garryjohanson][Have you an opinion on OpenCLC? Would that be out of bounds for Handmade Hero?]
[1:10:31][@insofaras][How would you handle errors if you were deep in the recursion? Is checking return values everywhere the best way?]
[1:11:18][@radlabgaming][I showed up late. Can you explain what introspection is?]
[1:16:22][@Popcorn0x90][Do you if Jon does "metaprogramming" for his language?]
[1:17:12][@insofaras][Regarding errors again, would this be a place where exceptions would actually be useful?]
[1:18:00][@evraire][Now that we have the preprocessor, do you plan to make more use of it going forward in Handmade Hero?]
[1:18:18][@hoganlong][Who is Jon and what language are you talking about?]
[1:18:39][@cvaucher][I'm writing a parser that looks pretty similar to this, but it runs on multi-GB files which takes a while. Any common approaches to use SIMD/multithreading to speed up text parsing? Seems more difficult since the characters aren't "independent" in the way pixels are]
[1:20:18][@desophos][This stream makes me feel like an extremely inferior and incompetent programmer. Do you approve of this?]
[1:22:58][@paulsm1th][How does metaprogramming change your workflow? Can you talk about incorporating generated code with the "regular" C files?]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.
