Recompile when an @embedFile changed

Help

I have an html file index_template.html that I then embed and use:

const std = @import("std");

const Index = struct {
    document_title: []const u8,
    main_title: []const u8,
    content: []const u8,
};

pub fn main(init: std.process.Init) !void {
    const io = init.io;
    const html = @embedFile("index_template.html");
    const stdout_file = std.Io.File.stdout();
    var buf: [100]u8 = undefined;
    var stdout = stdout_file.writer(io, &buf);
    const index: Index = .{
        .content = "Hello, world",
        .document_title = "Doc title",
        .main_title = "Guess what?",
    };
    try stdout.interface.print(html, index);
    try stdout.interface.flush();
}

When I run using zig run file.zig it works, but when I change the embedded file, it does not get re-run to incorporate those changes. How can I make that happen?

This is a one-off script for experimentation so I don’t think some of the existing solutions that use the build system would work, but maybe I’m wrong about that?

I thought it was a cache issue, but I’ve removed both .zig-cache and ~/.cache/zig and it doesn’t help.

Works fine for me on Zig 0.16, changes gets incorporated whether I run build-exe or run

Ugh. I’m such a dummy. I had two files named index_template.html and was changing the wrong one. Thank you for the rubber duck.
