Last active July 17, 2024 03:36 — forked from axelerator/Find unused variables in sass files
Find unused SCSS variables. Usage: `./find-unused-sass-variables.sh sassDir/`
#!/usr/bin/env bash
#
# Approach:
# 1. Find variable declaration in the form of "$my-var: anyvalue"
# 2. Loop through found variables and find occurrences of each variable in all sass files
# 3. Filter out vars that occurred only once

# This script adds a "Webclip" shortcut to your homescreen.
# The shortcut can be used to open a web page in full-screen mode,
# or to launch a custom URL (e.g. a third-party app).
# You'll be asked for a title, a URL, and an icon (from your camera roll)

hiilppp / redirect_to_pythonista.html
Created January 4, 2014 14:23
HTML file that opens Pythonista, where a specified script is executed, while the browser window closes in the background. This serves as workaround for IFTTT's lack of support for custom URL schemes in the URL parameter of Pushover's Channel.
<!DOCTYPE html>

<meta http-equiv="refresh" content="0; pythonista://foo.py&action=run&argv=bar"/>

This script looks for text files in a specific folder that include completed tasks ('@done') and timestamps, and then collects them into a daily log for the Day One journaling application. It works especially well when it's connected to IFTTT. See more details at http://craigeley.com/tagged/sifttter

# Based on tp-dailylog.rb by Brett Terpstra 2012 <http://brettterpstra.com>
# Multiple Date Function by Paul Hayes 2014 <http://paulrhayes.com>
#
# Notes:
# * Uses `mdfind` to locate a specific folder of IFTTT-generated text files changed in the last day
# * The location of your folder should be hardcoded in line 67, and the location of your Day One in line 66
# * Scans leading timestamps in each line matching the selected dates
# * Does not alter text files in any way

Hello, visitors! If you want an updated version of this styleguide in repo form with tons of real-life examples… check out Trellisheets! https://github.com/trello/trellisheets

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?
