Titanium's new CLI has got some sugar from Appcelerator's team, and is now a very powerful and extensible tool. Indeed, it has become a sort of Swiss knife for the Titanium developer, allowing to automate various tasks : sdk install / upgrade, project build / deployment, translatable strings extraction, etc. Apart from the official CLI tool, there are numerous other useful tools : alloy, gittio, etc. Even more, it is possible to hack most of these tools to extend their capacities through the commands concept.
This talk, given during the TiConf Amsterdam 2014 (http://ticonf.org), showcases a lot of command line tools for productive Titanium developers, and explains how to create custom commands.
