Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

$: (Dollar Colon) is basically a shorthand version of $LOAD_PATH. $: contains an array of paths that your script will search through when using require.
$0 (Dollar Zero) contains the name of the ruby program being run. This is typically the script name.
$* (Dollar Splat) is basically shorthand for ARGV. $* contains the command line arguments that were passed to the script.
$? (Dollar Question Mark) returns the exit status of the last child process to finish.
$$ (Dollar Dollar) returns the process number of the program currently being ran.
$~ (Dollar Tilde) contains the MatchData from the previous successful pattern match.
$1, $2, $3, $4 etc represent the content of the previous successful pattern match.
$& (Dollar Ampersand) contains the matched string from the previous successful pattern match.
$+ (Dollar Plus) contains the last match from the previous successful pattern match.
$` (Dollar Backtick) contains the string before the actual matched string of the previous successful pattern match.

Sublime Textの検索窓に日本語を入力するとEnterを押すなり文字が消えてしまうのですが、無理やり解決する方法を見つけました。ググってもこちらのバグレポートしか見つからなかったので報告です。

わたしの環境はMac OS XのSublime Text 3 (Build 3059)ですが、この解決方法はSublime Text 2 (Build 2220)にも対応しています。Windowsの場合は不明です。

ステップ1: Sublime Text 3の場合のみ: Default (OSX).sublime-keymapを編集可能にする

このステップはSublime Text 3の場合のみ必要です。Sublime Text 2の場合はステップ2に行って下さい。

# USAGE
# 1. Add 'factory_girl' in Gemfile as a dependency. But here, be careful. Factory Girl adds Active Support
#   as its dependency, so it is up to you add it in :development and :test group or add it for all envs.
#   For more details, read the comment from @cllns below.

# 2. Save this file in '/spec';

# 3. Load this file in 'spec_helper.rb' as the last require in the file, using:
#   require_relative './factory_girl_helper'

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start
