This is editline, packaged for Zig.

First, update your build.zig.zon:

zig fetch --save https://github.com/allyourcodebase/editline.git

Next, add this snippet to your build.zig script:

const editline_dep = b.dependency("editline", .{
    .target = target,
    .optimize = optimize,
});
your_compilation.linkLibrary(editline_dep.artifact("editline"));

This will provide a editline as a static library to your_compilation.
