# FontInstaller (by @olemoritz)

# This script installs a custom TTF font on iOS (system-wide).
# It can be used in one of two ways:

# 1. Simply run it in Pythonista, you'll be prompted for the URL of the font 
#    you'd like to install (if there's a URL in the clipboard, it'll be used by default)

# 2. Use it as an 'Open in...' handler, i.e. select this file in Pythonista's 'Open in...
#    menu' setting. This way, you can simply download a ttf file in Safari and open it in
#    Pythonista. The script will then automatically install the downloaded font.

# The script is inspired by the AnyFont app (https://itunes.apple.com/us/app/anyfont/id821560738)
# and the iOS integration of MyFonts (http://meta.myfonts.com/post/80802984786/install-fonts-from-myfonts-on-ios-7-devices)
