You need to build a system three times

the first time you don't know what you actually need, it's an exploration, plan to throw it away
the second time you think you know what you need so you over-architect, it'll be too restrictive, plan to throw it away
the third time you build what actually works

I like to think I came up with it at LucasArts twenty years ago, but at this point I don't know if it was generally in the zeitgeist.

https://github.com/jarro2783/cxxopts - couple thousand of lines, slightly prickly
getopt - dynamic link rather than bundle code
https://github.com/clibs/flag - c, compilable by C++ with a tweak
https://github.com/tanakh/cmdline - similar to cli11
cli11 - best interface, easy to use, rather big codebase
https://github.com/cofyc/argparse - small, modest, easy to use
https://github.com/p-ranav/argparse - small, mimics python's parser, easy to use, C++17

SON OF USD BUILD CLUB

Building a native Apple Silicon version of UsdView

This version of UsdView will have an Apple Silcon, Metal-native viewer, openimageio, and alembic support. It does not yet include MaterialX, OpenColorIO, or any of the other many options build_usd.py supports.

Successfully get usdview running on conda and M1 as follows:

Using the PySide6 PR by Jon Creighton

by our incantations we manipulate the dance of electrons in the microcosm, the very fabric of the universe itself

.? is equivalent to orelse unreachable. So to unwrap you can either do const y = x orelse <default>; or if (x) |unwrapped_x| {};

One way to debug ZLS lookups is to do zig run zls/zig-out/bin/build-runner.zig --pkg-begin "@build@" path/to/your/build.zig --pkg-end and make sure it outputs a list of packages.

export allocation functinos from zig

        pub fn getAllocator() std.mem.Allocator {
            return …;
