A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

{
    // Override point for customization after application launch.

    // Create a new window and assign directly to provided iVar
    _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    
    // Implementation of new init method
    MyCustomNavigationBar *navigationBar = [[MyCustomNavigationBar alloc] initWithFrame:CGRectZero];
    UINavigationController *navigationController = [[UINavigationController alloc] initWithCustomNavigationBar:navigationBar];

A keyboard shortcut to run tests with watchr

When developing in rails I use watchr to run the tests each time a file is saved, but lots of times I find my self adding a whitespace or a newline and saving just to trigger watchr and run the tests.

I wanted to have is a simple keyboard shortcut (like F15) to tell watchr to run the last spec, and mpartel (thx! : ) gave me an idea on how to do it, so here it is:

Dependencies

Obviously you need watchr, but we're also going to need pgrep that will help us find out the pid of the watchr process. So go ahead and do

sudo port install proctools
