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)
