How much it supports is totally up to the package providing the service. It’s going to be up to whoever builds a PHP parser to decide if they just want to just link the require
/ include
calls, or generate links on objects/variables.
As for Javascript, I just pushed a branch named variables
that has basic support for jumping to where a variable was defined. I need to run this through some more diverse code to make sure it works on more than just itself.
I have no plans to add such functionality to coffee-links
but would welcome a PR. CoffeeScript’s AST makes it very difficult to track down all variable declarations.
