… You could write Messenger patches in JavaScript? I guess it could look something like this:<\/p>\n

\r\nfunction CL_onCreatedElement(resid, root) {\r\n\tif (resid=="mainContentResID") {\r\n\t\tvar TabsAndAds=root.FindDescendent("TabsAndAds");\r\n\t\tif (TabsAndAds)\r\n\t\t\tTabsAndAds.SetValue("LayoutPos",new Value(-3));\r\n\t}\r\n}\r\n\r\nfunction Convo_onCreatedElement(resid, root) {\r\n\tif (resid=="convframeresid") {\r\n\t\tvar adbannergutter=root.FindDescendent("adbannergutter");\r\n\t\tif (adbannergutter)\r\n\t\t\tadbannergutter.SetValue("LayoutPos",-3);\r\n\t}\r\n}\r\n\r\n\/\/Patches contained in this file\r\nPatches=[\r\n\t{\r\n\t\tid: "ContactListAdvert",\r\n\t\tname: "Remove Contact-list Advertisement",\r\n\t\tversion: "1.0",\r\n\t\tauthor: "A. Nonymous",\r\n\t\twebsite: "http:\/\/www.google.com\/",\r\n\t\tonCreatedElement: CL_onCreatedElement\r\n\t},\r\n\t{\r\n\t\tid: "ConvoTextAdvert",\r\n\t\tname: "Remove Conversation Text Advertising",\r\n\t\tversion: "1.0",\r\n\t\tauthor: "A.

The above code works just like you’d expect it to, thanks to a new project I’m working on. For now it features only a very very small subset of the DirectUI library, just enough to make the above work (+ some debugging, obviously), but I plan to expand it to create an incredibly flexible platform for writing patches, skins, and later maybe even plugins.<\/p>\n
It’s the spiritual successor of the abandoned Project M or Modumes project. Basically Project M was too complex, by using Windows JScript and allowing any other language to write modules in, I faced some problems (mainly threading) that I could not reliable fix.<\/p>\n
To create something that could reliable interface with the DirectUI, I needed to have an enviroment where everything, or at least the parts interfacing with DirectUI, would be running from the main thread. My eye first fell on LUA<\/a>, later on Squirrel<\/a>, but in the end I figured that although those two scripting languages were incredibly powerful and small, I wanted something a tad more manageable. Eventually I figured the best language would be JavaScript, and Google’s V8 Engine<\/a>\u00a0allowed me all I needed:<\/p>\n
