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.

# 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)

badsyntax / find-unused-sass-variables.sh
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
