xvm - a bash snippet operating a few version managers

Currently supported are chruby, evm and kiex. kiex support requires evm.

Usage

First up, set up chruby, evm and kiex. Then, put this in your .bashrc:

source path-to-xvm/xvm.source.bash

# only needed if you want auto-change behaviour
if [ -n "$PS1" ]; then
  trap xvm DEBUG
fi

You can then call xvm to have versions set up according to version files (see below) in your current working directory. If you decide to use the auto-change behaviour, xvm is called automatically for you when you change directories (and at other times, too, so changes to version files are usually picked up immediately)

Version files

The well-known .ruby-version file is detected and used by xvm to call chruby. A .xvm-evm file will be used for calling evm use with the version in that file as argument. A .xvm-kiex file will be used for calling kiex use with the version in that file as argument. Kiex is only called after evm has been, since elixir versions often require a certain minimal erlang version.
