I am attempting to write a new availability condition plugin. The current documentation says that I am required to use YUI because the core availability is still written in it. I am attempting to install shifter and get a 404 error on a dependency for esprima. I have been unable to locate a version number although the package being searched for is called legacy.tar.gz.
Has anyone installed shifter recently? The documentation says to install 0.4.6 but would a later version work?
