ZSH bind a key to reload your RVM config
I'm working on a project that is in the process of upgrading from rails 2 to rails 3. Because I'm switching branches I have to frequently reload my RVM configuration to switch between 1.8.7 and 1.9.3 so I wanted an easier way to do it.
I wrote a function that will just cd out and back into my directory causing the normal hooking / loading mechanisms.
function reload-dir () {
cd ../
cd $OLDPWD
zle .accept-line
}
zle .accept-line is a zsh built-in that is the equivalent of pressing enter.
This was a new concept for me, but I can really see some power there. You can read more about it in section 4.7.3 http://zsh.sourceforge.net/Guide/zshguide04.html#l76
Having the function is nice, but I want to bind it to a key Ctrl+R
zle -N reload-dir
This again uses that zle built-in to register our function so that we can bind it with
bindkey '^r' reload-dir
