Project description

Google Fonts Tools

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

Google Fonts Official Glyph Sets (Encodings)

https://github.com/googlefonts/gftools/tree/master/Lib/gftools/encodings

Usage Examples

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] -gfb -a -o qa

Check a variable font family against the same family as static fonts:

gftools qa -f [vf_fonts] -fb [static_fonts] --diffenator --diffbrowsers -o ~/path/out

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

Package and PR a family update to google/fonts. Much more detailed documentation.

gftools packager "Family Sans" path/to/local/google/fonts -py

Installation

Please install these tools using pip:

pip install gftools

If you need to use gftools qa, you will need to install Harfbuzz, Cairo, FreeType and pkg-config. These can be installed on OS X using homebrew:

brew install cairo freetype harfbuzz pkg-config

Once You have installed these system packages, install gftools using the following command:

pip install gftools[qa]

Requirements and Dependencies

These tools depend on the submodule GlyphsInfo. Make sure the submodule is up to date by running:

git submodule update --init --recursive

gftool packager needs the command line git program in a version >= Git 2.5 (Q2 2015) in order to perform a shallow clone (--depth 1) of the font upstream repository and branch. This is not supported by pygit2/libgit2 yet.

Google Fonts API Key

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 text file located on your system at ~/.gf-api-key (where ~ is your home directory), which contains the following:

[Credentials]
key = your-newly-generated-googlefonts-api-key
