This function automatically grabs the latest git tag and, based on keyword (major, minor, patch), adds a new tag. (e.g. git_tag patch for v1.2.0 would create v1.2.1)

Drop this into your ~/.bash_profile and run source ~/.bash_profile to use it.

This example shows how to setup an environment running Rails 3 beta under 1.9.2-head with a 'rails3' gem set.
∴ rvm update --head
# ((Open a new shell)) or do 'rvm reload'
# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.2-head
# Switch to 1.9.2-head and gemset rails3, create if it doesn't exist.
∴ rvm --create use 1.9.2-head@rails3
You can’t perform that action at this time.
