   some library authors have funny ideas about how stuff should work (looking at you, tinyobjloader)

     One of the reasons I tend to roll my own if it's feasible.

     @gentoobro yeah, obj is dead simple and writing a parser is a chore, not a challenge, that's why I thought I would try using a library

     @gentoobro the parser I wrote for my templeos thing is about 1/8 of tinyobjloader-c (1735 lines) and it also converts the data to a custom format.

     > wc -l objtoh3d.c 227 objtoh3d.c

     to be fair it's a special purpose tool that's in no way ready for deployment - it doesn't handle bad files - but most of the time that's all you need.

     @gentoobro I also found an even smaller (and older) file:

     > wc -l objclass.cpp 124 objclass.cpp

     It's full of bangers :dementia:

     That, um, appears to be a floating point exact equality test, which is seldom what you want...

     @gentoobro it's an integer vector, so the comparison works as expected. I don't know if the edit federated, the gist of it is that I did a backwards scan and broke the loop on the first match, which was always on the first iteration because of the j = i; as a result, there was no vertex deduplication. I think I was trying to fix a bug with repeating vertices, and for some reason I didn't add a separate counter and tried to do it with just two variables.

     The main problem with using a lib for something like an OBJ loader is that learning the lib, its quirks and its bugs often takes longer than just writing your own. And God forbid the library author decides to "update" it and change around the API for no reason.

     The majority of the code for my OBJ parser is around 20 years old now. Basically no updates or maintenance needed during that time.
