Override rokoroku's Darcula theme to be closer to the one from RubyMine 2018.2. This is the closest look I could get without making any PR to base plugins. It is not meant to be used as a plugin since I don't want to maintain one. To use it simply install plugins from base plugins sections and paste content of settings.json at the end of yours.

This is based on the following plugins:

• Darcula theme
• Ruby
• JetBrains font (not a plugin)

To be clear everything beyond this point is way beyond my understanding of vscode grammar / regexp, so I would not be able to solve any of those in a near future. If you can (and do) please ping me so I can update this to be as close as possible from the original theme.

• Methods calls are yellow (I was not able to override entity.name.function.ruby by meta.function-call.ruby)
• Local variables are white (Since the method call are only detected as local variables by the Ruby extension there was way to many blue so I kept it white, this could be put back if Rails special method are implemented in the ruby extension (or a new rails extension)

• Unused parameters/variables should be grey

• Handle Rails special method (such as model callbacks, validations, relations, and controller callbacks)
• Tag variables to see if they come from parameters or a local assignation (purple/blue in RubyMine)
