johan / GM_queryContentVar.js
Created September 27, 2010 05:01
Lets a GM script safely read variables from the content scope (untested)
// Query page javascript for the identifier "name", and call callback(value),
// when found, or undefined, if not found or some error occurred. This works
// only for values that can be JSON serialized -- numbers, strings, booleans,
// null, or nested structures like Arrays and Objects that only contain above
// mentioned types of data.
function queryContentVar(name, callback) {
// makes a random 20-char lowercase id
function random() {
var rand = '';
while (rand.length < 20)

getXPathTo / getRootXPathTo

I was looking for two clean, tiny and elegant element-to-xpath functions producing short and complete xpaths like id("main")/ul/li[3] or /html/body/ul/li[3] for a given element, and figured I'd just craft my own.

Created March 26, 2011 10:25
Like fgrep / egrep (symlink it as egrep-count to regexp match by default), but for more than one pattern at a time, generating tsv output, and where you list all the patterns and what you want the count columns to be named as a JSON object on stdin.

johan / gravatar.rb
Created April 3, 2011 09:01
Takes a list of email addresses (or files with email addresses) and lists gravatars for them, if set.

require 'net/http'
require 'uri'
$unknown_gravatar = 'd5fe5cbcc31cff5f8ac010db72eb000c'
