Viking Coding Adventures

This is a running work in progress post about what and how I set up my Macbook Pro to develop Rails applications.

Since we studied the Ruby language first in the Viking Code School curriculum, this is in addition to my previous post on my Ruby setup.

I basically did the steps as described on this excellent tutorial by Jump Start Lab (as recommended by dróttinn Erik at the Viking Code School) with some minor changes:

Homebrew's 'brew doctor' command indicated that I did not have the Xcode's Command Line Tools installed amongst some other misc warnings.  I didn't pay attention to those since I figured they would dissipate once I updated Xcode (and they did).

I updated Xcode and its Command Line Tools to the latest (6.0.1)

Ruby 2.1 - making it the default version via RVM (previously v2.0.0p481)

Installed Postgres DB

Additionally I made the following aliases in my .bash-profile file so it's easier to start/stop/check the Postgres server:

alias gopostg alias stoppostg alias statpostg

Addendum:

Following Michael Hartl's guide: Ruby on Rails Sublime Text Setup Tutorial, I've added a couple of useful packages to Sublime:

Added SublimeERB

Added Alternative Autocompletion

I did not want to update Git (even thought the post encouraged it) because I am familiar with the version already in place and didn't want to chance breaking it at the moment since I have a mountain of work ahead.

Ironically, the post didn't mention the need to install Rails, but in fairness it was a Ruby tutorial not Rails. I had to look that up on Rails Guide's Getting Started with Rails page to make sure the command was the expected: gem install rails (it was and it installed 25 gems).

NB: Homebrew's 'doctor' call now shows me these warnings when run:

However, since I don't know if "everything [I] use Homebrew for is working fine..." or not (seems to be ok), I'm not going to follow up with the suggested 'prune/link/unlink' methods until I run into a related problem and/or I know more about the system first.

That's it for now; onward to the projects!

As I'm working on projects for the Viking Code School I'm customizing my Sublime Text 2 (ST2) with tools and various configurations to make the process easier.

Here's what I have so far:

Package Control - package manager

Sass - for Sass syntax highlighting, etc.

SublimeREPL - for bash, Pry & IRB (and others!) CLI terminals from inside ST2

Sublimipsum - inject Lorem Ipsum... into page copy

Git - Plugin for some git integration into ST2.

Ruby Debugger - Interactive debugger for sublime

Soda Theme - Dark and light custom UI themes for Sublime Text

with the Additional Features and Colour Scheme

Quick Look - Use OSX's Quick Look feature to view images from within the editor.

tldr: Setup Ruby's IRB or Pry CLI in Sublime 2 using SublimeREPL by following these install guides for SublimeREPL, Pry, then implement the workaround below to get it working correctly.

There's a bug in SublimeREPL which prevents the any version of Pry > 10.0 from working correctly in Sublime 2. Applying these changes locally to SublimeREPL's config file for Pry and restarting ST2 allowed the Pry CLI to function correctly in Sublime 2.

Full version:

I wanted to have syntax highlighting in the Ruby IRB and began looking at how to do this. Then it occurred to me that ST2 has command line interface (CLI) capabilities and I could set ST2 to run the CLI for Ruby and other languages and I wouldn't have to drop out of ST2 to the terminal to access the IRB.

I found that SublimeREPL (docs) is the currently preferred ST2 package to add this functionality to Sublime.

After running through the instructions, an IRB CLI was indeed available through ST2, however, along my journey there were many posts about using Pry as the CLI for Ruby as it added a "number of advanced features" that the IRB did not. So I went about setting Pry up and getting it working in Sublime.

This is where I ran into a bit of a snag...

I saw this error (in ST2) when Pry wouldn't launch correctly in ST2: 

/Users/phyman/Library/Application Support/Sublime Text 2/Packages/SublimeREPL/config/Ruby/pry_repl.rb:37:in `<main>': uninitialized constant Pry::InputCompleter (NameError)

Digging into it I found that there is a bug in SublimeREPL that was causing Pry to not load/work correctly in ST2. Some suggested downgrading Pry which I did, but it just didn't feel right. Then took a look at the pull request for the fix, found it wasn't merged yet and followed it through to the file changes. 

I then opened up my local SublimeREPL /config/Ruby/pry_repl.rb file and made the changes and updated the file myself.

After restarting ST2, I could now invoke the Pry CLI from within Sublime 2 with no errors and the CLI was working as expected!

Got a permission denied message while trying to push my changes back to the remote server:

[phyman@SilverSurfer]: ~/git/viking_school/VikingSchoolPrep$ git push origin master remote: Permission to phyman/VikingSchoolPrep.git denied to purposetw-deploy. fatal: unable to access 'https://github.com/phyman/VikingSchoolPrep.git/': The requested URL returned error: 403

Added SSH key to GitHub's key store: https://github.com/settings/ssh

Then followed theses instructions to change the connection type when using SSH on the CLI with GitHub.
