String object extensions for handling proper indentation duration HEREDOC interpolation of multi-line strings.

	# Created in response to Stack Overflow question:
	# http://stackoverflow.com/questions/38504004/interpolate-multiline-string-with-correct-indent

	module CoreExtensions
	module String
	module Heredoc

	# Special character to flag lines that are part of a multiline HEREDOC interpolation
	# Any character that is not part of the output string will work. Using "\r" because
	# it's rarely used in hard-coded strings.

Created April 28, 2015 18:11

Command line options for ` rails new --help ` (Rails 4.2). Useful for planning new Ruby on Rails app. 'Where can I find options for “rails new” command?'

	Because I couldn't find these with a quick Google search on 28 April 2015:

	Usage:
	rails new APP_PATH [options]

	Options:
	-r, [--ruby=PATH] # Path to the Ruby binary of your choice
	# Default: /home/brian/.rvm/rubies/ruby-2.2.0/bin/ruby
	-m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL)
	[--skip-gemfile], [--no-skip-gemfile] # Don't create a Gemfile

Last active April 26, 2022 09:36

Converting a folder full of markdown files, each linking to each other ... convert those files to HTML, and convert the relative links to point to the new html files. Add code highlighting with highlight.js . Finally serve up the result as a static web site.

	$> echo '<head>' >> index.html
	$> echo '' >> index.html
