zig-plain-argparse

[WIP] A "plain" argument parsing library for Zig.

The key feature is that it parses arguments imperatively (not declaratively).

This makes it lower-level than zig-clap, which is more declarative (and probably better for general use).

Motiviation

Hopefully this more imperitive design reduce the amount of compile time magic . :)

I couldn't understand zig-clap well enough to implement "proper" subcommands.

In this more imperative style of parsing, subcommands are not a problem because they are just positional values.

You can parse a subcommand as a Zig enum, then create a new parser for the remaining arguments.

Also another plus side is zero allocation ;)

Features

• Good error messages (descriptive errors)
• Zero allocation (Parser is a thin wrapper around [][]const u8)
• Imperative argument parsing (hopefully) minimizes comptime complexity
• Support for subcommands follows nicely from the simplicity
  • See examples for this (TODO)

Missing features (TODO?)

• Automatic help generation
  • This would be nice
• More tests
