A word of advice on Bundler and Gems from git

At times (especially after Rails version upgrades) some Gems don't work out of the box so I usually spend some time on GitHub looking through the network graph for a fork that fixes the issue.

This works great and you usually end up with a well working plugin to continue working. Bundler supports this by loading the gem from the git source:

gem 'rails', :git => 'https://github.com/rails/rails.git'

Only problem with this approach: Forks are usually a moving target in regards to their longevity. People tend to delete them once the pull request gets merged, or simply forget about them.

Neither is desirable and today it bit me for the first time, I had referenced a fork that got deleted but contained a important fix for my project on a gem that was not yet 3.1 ready. Fortunately the project has moved along and the master already included the fix (and didn't introduce new issues). But it sure taught that I should always keep my own fork of code I decide to depend upon.

Make GNU screen xterm-256color work on OSX

I just ran into this and spend like 2 hours with Linux genius Jam trying to figure out why in the heck I could run Vim in 256 colors mode on my server while once I started screen it didn't work any more.

The issue was two fold. a) My local Terminal.app was reporting itself as xterm-color instead of xterm-256color. You have to update this setting in your Terminal app here:

 

Once done you only need to edit your .screenrc to include the following 3 lines:

 

# terminfo and termcap for nice 256 color terminal
# allow bold colors - necessary for some reason
attrcolor b ".I"
# tell screen how to set colors. AB = background, AF=foreground
termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm'
# erase background with current bg color
defbce "on" 
# set TERM
term screen-256color-bce

Problem is: Even if you set your .screenrc correctly, it won't matter if your terminal is not reporting the correct version string in the first place..
