zig wrapper for the snowball stemmer

NOTE: this is a work in progress, and not yet ready for use.

Requirements

• zig >= 0.14

how to use?

Add this package to your zig project:

$ zig fetch --save=snowballstem git+https://github.com/thekorn/snowballstem.zig.git#main

Add dependency and import to the build.zig file:

...
const snowballstem = b.dependency("snowballstem", .{
    .target = target,
    .optimize = optimize,
});
...
exe.root_module.addImport("snowballstem", snowballstem.module("snowballstem"));

And then, just use it in the code:

const std = @import("std");

const Stemmer = @import("snowballstem");

pub fn main() !void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}){};
    defer std.debug.assert(gpa.deinit() == .ok);
    const alloc = gpa.allocator();

    const stemmer = try Stemmer.list(alloc);
    defer alloc.free(stemmer);

    std.debug.print(">>> {s}\n", .{stemmer});
}

Tests

Using nix tests can be run like

$ nix develop -c zig build test --summary all

TODOS

the build is not correct, first build sometimes fails
implement the stemmer
make wasm buildable
how to handle german umlauts?
write test for german stemmer to check against the upstream test suite
add other languages to tests (esp english)
