chrisross / flat.js

Created July 11, 2020 13:47

Simple object flattener.

	/**
	* Converts an object or array to an 1 dimensional object
	* with dot delimited key paths as keys
	*
	* @param {(Object\|Array)} oldObject
	* @returns {Object}
	*/
	const flat = oldObject => {
	// This scope is just to create the new object, to avoid mutating state
	const newObj = {};

Simple Fibonacci sequence generator using Ruby

	def fibonacci(limit = 10)
	limit.times.each_with_object([0,1]) do \|elem, accum\|
	accum << accum[-1] + accum[-2]
	end
	end

	# Examples

	#!/usr/bin/env bash

	# Hotkeys (While playing):
	# @see http://linux.die.net/man/1/ffplay
	# q, ESC Quit
	# f Toggle full screen
	# p, SPC Pause

chrisross / autoexec.py

Last active November 26, 2018 16:51

This script scans for connected usb media, selects the first one and creates a playlist from the USB's top-level directory. Connect to the same network as the raspberry pi and scp the script to /home/osmc/.kodi/userdata (this may vary depending on OS). This is meant for a Raspberry Pi used as a media player, with OSMC installed.

	# Autoplay videodirectory
	import os, xbmc, time

	usb_dir = "/media" # path of external media
	delay = 10 # seconds to delay media player

	# Collect directories (USBs) in usb directory
	usb_list = []
	for fname in os.listdir(usb_dir):
	fpath = os.path.join(usb_dir, fname)

chrisross / sass_index_guardfile.rb

Last active March 3, 2016 12:10

A simple guardfile for a compass project, that updates each directory within the `sass_dir` with an index file called `_all.scss` in which there are imports for every other scss file in that folder making importation of all files simple. update sass_dir per project.

	# Example Directory structure
	# /path/to/project
	# \|───scss
	# \| \|───library
	# \| \| \|───_all.scss <------- creates/updates this file
	# \| \| \|───_typography.scss
	# \| \| \|───_structure.scss
	# \| \| └───_responsive.scss
	# \| \|───modules
	# \| \| \|───_all.scss <------- and this file

chrisross / git_diff_tags

Created July 25, 2013 19:23

A Bash alias for a script to list files that have changed or been added between the last two tags.

alias gdt="git tag | sort -bt. -k1,1 -k2,2n -k3,3n -k4,4n -k5,5n | tail -n 2 | xargs git diff --name-only"

chrisross / units_sass_extensions.rb

Last active March 3, 2016 11:53

This Sass extension adds the ability to strip or append units to a number with ease, which can be annoying in Sass. Strip units works on all unit values, eg. 12in, 0.56pt, 800px, 34em, except % but that is already easy to add to unitless numbers.

	#!/usr/bin/env ruby

	# To implement extension, run this command in a shell:
	# $ sass -i -r ./units_sass_extension.rb
	# Or require it in compass config
	# require './units_sass_extension'
	module Sass::Script::Functions

	#
	# Strips units from a value, e.g. '10px' or '10in' becomes 10

chrisross / gcd_sass_extension.rb

Last active March 3, 2016 11:55

This sass extension utilises the Greated Common Divisor (gcd) algorithm to reduce duplicate styles, especially when making your own grid system.

	#!/usr/bin/env ruby

	# To implement extension, run this command in a shell:
	# $ sass -i -r ./gcd_sass_extension.rb
	# Or require it in compass config
	# require './gcd_sass_extension'
	module Sass::Script::Functions

	#
	# Uses the 'greatest common divisor' algorithm to work out if a fraction

chrisross / gcd_sass_script.scss

Last active February 23, 2023 23:27

This Sass (SCSS) function utilises the Greated Common Divisor (gcd) to reduce duplicate styles.

	// Algorithm to calculate the Lowest Common Denominator
	@function gcd($a, $b){
	@if $b == 0 {
	@return $a;
	} @else {
	@return gcd($b, $a%$b);
	}
	}

	// Example Use-case:

chrisross / colors.rb

Created July 3, 2013 13:59 — forked from nhocki/colors.rb

	module Colors
	def colorize(text, color_code)
	"\033[#{color_code}m#{text}\033[0m"
	end

	{
	:black => 30,
	:red => 31,
	:green => 32,
	:yellow => 33,

	# Example Directory structure
	# /path/to/project
