This mostly works. Subcommands are utterly broken because we blindly consume an additional argument to get the program name, which we should not do. This code was always kind of spaghetti, but it's getting worse. I want to refactor it into something that doesn't make me cringe, but at the same time, this project was intended to be a means to an end rather than the end itself, and it kind of feels a bit silly to spend a ton of time on it. On the other hand, relying on it for other projects seems silly if it's a fragile mess. The goal was to get it into a usable state and then hack on it as necessary, but it still has a ways to go to get there, and working on it is kind of painful, in an existential fashion. Perhaps I will attempt to rewrite it, get halfway, and stall forever. Thanks for reading my cool commit message blog. Bye.
== nearly obvious command line interface parser A zig library for composing declarative command-line interfaces. Heavily inspired by https://click.palletsprojects.com/[click] for Python. == Extemporaneous Bloviation [quote, George "Albert Einstein" Washington] ____ The alarm rings, and expletives spill from my mouth—instinctively, before any neuron has a chance to fire. You'd think this would get easier, having done it at least 12000 times, but I guess it just goes to show that practice does not necessarily converge on perfection, no matter what infinite limit t approaches. Eyes clamped shut against the encroaching underglow spilling from the curtains, I stretch my arms straight out from my sides and proceed to lose my balance, flying horizontally off of the mattress. An attempt at attitude control fails vigorously and I begin cartwheeling through open space, asserting a lopsided trajectory that intersects with the roof of the house. Passing through it unencumbered, I careen skyward and watch the ground recede into the distance, as the features of the landscape shrink and pop out of existence. ____ == Hello Requires Zig `0.10.0` or maybe better. Uses stage2-only features. === Features * short- (`-s`) and long- (`--long`) style options * short options can be chained (e.g. `-abc` is the same as `-a -b -c`) * conventional `--` to force early of argument parsing * option values are deserialized into rich types using conversion callback functions * can specify default values for options that may be omitted * options can be bound to load from environmental variables if not specified directly * nested subcommands (e.g. for `git`-style CLIs (`command subcommand subsubcommand`)) === Planned * help text generation * better error reporting * better build system === Under consideration * multi-value option flags * shell completion integration * `--long=value` style of value specification * Is it actually possible for a published written document to truly be extemporaneous? === Use `zig build demo` for a demo. Otherwise just copy the file or use a submodule or something. == LICENSE INTERNET SOFTWARE CONSORTIUM LICENSE
