Install

Open a terminal window and run:

sudo gem install wirble && echo -n "require 'rubygems'\nrequire 'wirble'\nWirble.init\nWirble.colorize" >> ~/.irbrc

Usage

Now that Wirble is installed and irbrc is properly configured, (re)open irb and then you can start using the "TAB" key to auto-complete while typing a Ruby instruction. Only the results will be colorized, not the instructions typed.

[FIX] VLC is unable to open the MRL (smb://)

Image
When I tried to open remote video files with VLC via a Samba share I got this error message: Your input can't be opened: VLC is unable to open the MRL 'smb://...' It seems that this problem is related to credentials and can be fixed by entering the credentials for the Samba share in the VLC preferences (Tools > Preferences > Input / Codecs > Access Modules > SMB Input): Note: I only experienced this problem when accessing remote files with PCManFM.
