libdirectory of the gem to the load path of the Opal
opaldirectory (and the
libdirectory contains the code the pushes
opaldir to the opal's load path)
opalexecutable you can write something like
$ opal -I../opal-browser/opal --gem paggio --compile your_code.rb
require 'opal-browser'before compiling the code to register all paths
A version selector on Try Opal would be amazingly helpful.
In this case I just know that making the second parameter true made something work in 0.11 that had worked in 0.10. I don't know which one the bug is in though, just because it worked before doesn't mean it was working as intended.
