This project contains tools used for working with the Google Fonts collection, plus Google Fonts Glyph Set Documentation in the /encodings subdirectory. While these tools are primarily intended for contributors to the Google Fonts project, anyone who works with fonts could find them useful.
The tools and files under this directory are available under the Apache License v2.0, for details see LICENSE
https://github.com/googlefonts/gftools/tree/master/Lib/gftools/encodings
Compare fonts:
gftools compare-font font1.ttf font2.ttf
Add a METADATA.pb to a family directory
gftools add-font ../ofl/newfamily
Sanity check a family directory:
gftools sanity-check --repair_script=/tmp/fix.py ../ofl/josefinsans
gftools sanity-check --repair_script=/tmp/fix.py --fix_type=fsSelection ../ufl
Check a font family against the same family hosted on Google Fonts:
gftools qa [fonts.ttf] -a -o qa
Add a DSIG table to a font
gftools fix-dsig font1.ttf
Fix a non hinted font
gftools fix-nonhinting font_in.ttf font_out.ttf
Please install these tools using pip:
pip install git+https://github.com/googlefonts/gftools
Note: We're in the middle of upgrading the scripts to support Python 3 so we don't have a Python 3 compatible pypi package yet.
These tools are intended to work with both Python 2.7 and Python 3, If a tool isn't working with Python 3 please make an issue. Python 2 support is being phased out and gftools will be Python 3 only soon. Pull Requests welcome! :)
These tools depend on the submodule GlyphsInfo.
Make sure the submodule is up to date by running:
git submodule update --init --recursive
Running gftools-qa also requires Harfbuzz, Cairo, FreeType and pkg-config. These can be installed on OS X using homebrew:
brew install cairo freetype harfbuzz pkg-config
In order to use the scripts gftools qa and gftools family-html-snippet, you will need to generate a Google Fonts api key, https://developers.google.com/fonts/. You will then need to create a new file located on your system at ~/.gf-api-key, which contains the following:
[Credentials]
key = your-newly-generated-googlefonts-api-key
