How do you set the application icon in golang?

Question

I\'ve just created my first go application on Windows.

How do I give it an icon?

There doesn\'t seem to be any build flags to do this, and I know golang doesn\'t

You can use a tool like akavel/rsrc in order to generate a .syso file with specified resources embedded in .rsrc section, aimed for consumption by Go linker when building Win32 excecutables.

See as an example the lxn/walk application, which embeds other metadata in its executable.

rsrc [-manifest FILE.exe.manifest] [-ico FILE.ico[,FILE2.ico...]] -o FILE.syso

-ico="": comma-separated list of paths to .ico files to embed

This differs from embedding binary data into a go program.
For that, use jteeuwen/go-bindata.

To access asset data, we use the Asset(string) []byte function which is included in the generated output.

data := Asset("pub/style/foo.css")
if len(data) == 0 {
    // Asset was not found.
}

// use asset data
