sqlite

Rust stdlib code is quite high quality although not particularly dense due to large amount of comments. Start from the docs, and click any source link: https://doc.rust-lang.org/std/vec/struct.Vec.html Sqlite is supposedly high quality C code: https://github.com/smparkes/sqlite For videos of someone (Casey Muratori) writing video game code and debugging it, Handmade Hero: https://handmadehero.org/ A blog post about how to write code by the same author: https://caseymuratori.com/blog_0015 For how to implement a fairly advanced type system, Typing Haskell in Haskell: https://gist.github.com/chrisdone/0075a16b32bfd4f62b7b But, honestly, you're probably better off writing code yourself and learning by doing.

Because it's an artificial constraint that makes code worse. You end up with a whole bunch of functions that have only a single call-site and half a dozen parameters that don't make much sense. If you can only understand what a function does by looking at the call site then the function is no longer a self-contained piece of functionality and it shouldn't exist. When you write very simple code you can have short functions that do one thing. When you work on more complex projects some functions will just be 300 lines long and breaking them up will just make the code harder to understand and harder to work with. Take sqlite for instance: https://github.com/smparkes/sqlite/blob/master/src/vdbeaux.c You'll find plenty of cases where functions do multiple things in sequence and those functions are long-ish because of it, and some "clean code"

c = pMem->flags; sqlite3VdbeMemRelease(pMem); pMem->flags = MEM_Str|MEM_Term|(c&(MEM_AffMask|MEM_Subtype)); 'pMem->flags' is a u16[1]. Shouldn't it be copied to 'c'. How can 'sqlite3VdbeMemRelease' alter the value of 'c'. [1]https://github.com/smparkes/sqlite/blob/8caf9219240123fbe6cf...

I had some problems expressing what bothers me clearly and edited the comment heavily, perhaps it makes more sense now. You're right it is not that surprising, but it's still disappointing that even the most rudimentary best practices are not adopted. Have a look at sqllite for comparison, also an open source project, also in C, certainly less mission critical, and what a difference: https://github.com/smparkes/sqlite/tree/master/test https://github.com/smparkes/sqlite/blob/master/src/rowset.c
