You need to put this function into window, otherwise the onclick event won't find it.

window.copy_path = copy_path;

Or you can declare it directly like this:

Suggested change
function copy_path(but) {
window.copy_path = function(but) {

(and don't forget the ; at the end ;) )

var parent = but.parentElement;
var path = [];

var el = document.createElement('textarea');
el.value = 'use ' + path.join('::') + ';';
el.setAttribute('readonly', '');
// To not make it appear on the screen.
el.style.position = 'absolute';
el.style.left = '-9999px';
onEach(parent.childNodes, function(child) {
if (child.tagName === 'A') {
path.push(child.textContent);
}
});

document.body.appendChild(el);
el.select();
document.execCommand('copy');
document.body.removeChild(el);
var el = document.createElement('textarea');
el.value = 'use ' + path.join('::') + ';';
el.setAttribute('readonly', '');
// To not make it appear on the screen.
el.style.position = 'absolute';
el.style.left = '-9999px';

but.textContent = '✓';
}
document.body.appendChild(el);
el.select();
document.execCommand('copy');
document.body.removeChild(el);

but.textContent = '✓';

if (reset_button_timeout !== null) {
window.clearTimeout(reset_button_timeout);
}

function reset_button() {
but.textContent = '⎘';
reset_button_timeout = null;
}

reset_button_timeout = window.setTimeout(reset_button, 1000);
}
}());
