TruFont is a font-editing application written with Python3, ufoLib, defcon and PyQt5.

1. Install Python 3

   • OS X: Install using Homebrew: brew install python3 && brew linkapps python3
   • Windows: Download installer from https://www.python.org/downloads/
   • Linux: It's usually packaged with the OS.

2. Set up a new Python virtual environment using virtualenv.

   • Install or update the virtualenv module with pip3 install --upgrade virtualenv. You may require sudo access on Linux. Alternatively, you can install it in the Python user directory: pip3 install --user --upgrade virtualenv.
   • Create a new virtual environment, here called '.venv':
     • OSX and Windows: python3 -m virtualenv .venv
     • Linux: You need to give the virtualenv access to the system's site-packages folder to make sure PyQt5 can be imported: python3 -m virtualenv --system-site-packages .venv
   • Activate the newly created environment:
     • OS X or Linux: source .venv/bin/activate
     • Windows: .venv\Scripts\activate.bat
   • Run deactivate when you wish to exit the virtual environment.

3. Install PyQt5 (version 5.5.0 or greater):

   • OS X and Windows: pip install pyqt5
   • Linux: Follow instructions to compile PyQt5 (and SIP) from source: http://pyqt.sourceforge.net/Docs/PyQt5/installation.html

4. Install other dependencies: pip3 install -r requirements.txt

5. Install TruFont: pip3 install . Or if you wish to edit the source code, install in "editable" mode: pip3 install -e .

6. Run the app as trufont.
