// Scripting Chrome for awesome

// This script finds all matching history entries
// in the chrome://chrome/history/ panel and turns
// the checkboxes on so you don't have to click through
// all of them.

// Retrieve all entries from the currently displayed
// history list (use the Search history to limit your
// list first).
var entries = document.querySelectorAll('.entry');
entries = Array.prototype.slice.apply(entries);

// Set up a RegExp to test URLs. I only want to match
// those URLs that are invalid in the new URL scheme.
var matcher = /^https:\/\/[a-z.]+\.klemen\/public/g;

// Find all entries that match
var matches = entries.filter(function(item) {
    var a = item.querySelector('a');
    if (a) return matcher.test(a.href);
    return false;
});

// Loop over the matches and select the checkboxes.
matches.forEach(function(item) {
    var checkbox = item.querySelector('input');
    if (checkbox) checkbox.checked = true;
