在TextMate中使用具有不同gemsets的RVM

Question

I have set up RVM and made individual gemsets for my projects as per the RVM best practices . Now running a test file in TextMate dosen't work and I have read here what to do. The problem is that it won't work because the guide expects me to have just one gemset (they call it "Rails3"). I normally have 2-3 projects open at a time (using different gemsets) so I can't effectively use this approach.

Have any of you solved that problem?

Answer 1

I've found the RVM wrappers method to be very buggy, and as you've discovered it doesn't work at all with gemsets unless you do a lot of tedious setup.

I've had some success using the following script as TM_RUBY :

#!/bin/bash

base_dir=${TM_PROJECT_DIRECTORY:-$PWD}
cd $base_dir
exec $MY_RUBY_HOME/bin/ruby $*

As long as you're in a TextMate project and you have a .rvmrc file in the project root it will run your code in the Ruby version and gemset specified in the .rvmrc . The cd makes sure RVM discovers the .rvmrc .

Put the code above into ~/bin/textmate_ruby_wrapper and then go to Preferences > Advanced > Shell Variables and set TM_RUBY to that same path.

Answer 2

I've found this solution which is even simpler. Under the TextMate Preferences - Advanced - Shell Variables:

Set your GEM_HOME :

env | grep GEM_HOME | awk '{ sub(/GEM_HOME=/, ""); print }'

Set your GEM_PATH :

env | grep GEM_PATH | awk '{ sub(/GEM_PATH=/, ""); print }'
