I am resisting the urge to try to codegolf this into fewer lines. It's going to end up being a sprawl, but it is what it is. The main part of this that will actually require intelligent thought is the column wrapping and alignment. I think I will probably be implementing a custom writer style thing to handle that. There are a lot of annoying loose odds and ends here. Choice types should list all the choices. But we can't necessarily assume that an enum-typed parameter is a choice type (only if it uses the default converter). Perhaps the conversion stuff should be turned into an interface that can also be responsible for converting the default value and providing additional information. For now I will probably just hack it so that I can move on to other things.
== 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
