It's completely possible to implement printf. here is my impl (not 100% correct yet) of snprintf for my custom libc implemented on top of a platform I'm working on <https://zigbin.io/ab1e79> The va_arg stuff are extern because zig's va arg stuff is pretty broken at the moment. Here's a C++ game ported to web using said libc running on top of the custom platform and web frontend that implements the platform ABI <https://cloudef.pw/sorvi/#supertux.sorvi> (you might need javascript.options.wasm_js_promise_integration enabled if using firefox based browser)

yeah I just thought there are "compiler shenanigans" involved with printf! zig's va arg being broken is sad, I am so zig-pilled, I wish we could just call extern "C" functions with a tuple in place of va arg =D

The only thing C compilers do for printf, is static analyze the format string for API usage errors. Afaik such isn't possible in zig currently. But idk why'd you downgrade yourself to using the printf interface, when std.Io.Writer has a `print` interface where fmt is comptime and args can be reflected so it catches errors without special compiler shenigans.

>>Cloude+p3
I'm thinking: do a translate-c and then statically catch errors using my zig-clr tool.
