Ruby and Postgres Regular Expression Syntaxes

Ruby's regular expressions are unusually powerful. Postgres' regular expressions are not as powerful, but they come close; close enough that it's possible to do many pattern-based queries and string transformations entirely in a query.

And sometimes, it's very useful to have a single regular expression that works

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).

	#!/usr/bin/env python3

	import sys
	import re
	from zipfile import ZipFile
	from getpass import getpass

	if len(sys.argv) == 1:
	print("Usage: {} ZIP_FILE(S)...".format(sys.argv[0]))
	exit(0)

	class String
	def to_camel
	self.split(/_/).map(&:capitalize).join
	# or
	#self.split(/_/).map{ \|w\| w[0] = w[0].upcase; w }.join
	end

	def to_snake
	self.gsub(/([A-Z]+)([A-Z][a-z])/, '\1_\2')
	.gsub(/([a-z\d])([A-Z])/, '\1_\2')
