Source Sans Pro

Source Sans Pro is a set of OpenType fonts that have been designed to work well in user interface (UI) environments. In addition to a functional OpenType font, this open source project provides all of the source files that were used to build this OpenType font by using the AFDKO makeotf tool.

Building the fonts from source

Requirements

To build the binary font files from source, you need to have installed the Adobe Font Development Kit for OpenType (AFDKO). The AFDKO tools are widely used for font development today, and are part of most font editor applications.

Building one font

The key to building OTF or TTF fonts is makeotf, which is part of the AFDKO toolset. Information and usage instructions can be found by executing makeotf -h.

In this repository, all necessary files are in place for building the OTF and TTF fonts. For example, build a binary OTF font for the Regular style like this:

$ cd Roman/Regular/
$ makeotf -r

Building all fonts

For convenience, a shell script named build is provided in the root directory. It builds all OTFs and TTFs, and can be executed by typing:

$ ./build.sh

or this on Windows:

> build.cmd

Building with make

If you want to build directly from masters instead of the instances stored in the repository, or to avoid building all files repetitively, run:

$ make

and it will get everything up to date. To generate only the font.ufo instances from the masters, run:

$ make instances

Note: because font.ufo instances are stored in the repository, you may have to delete them first from your working tree before building from masters; see below.

To clean up makeotf's defaults and other log files, run:

$ make clean

or to remove all build artefacts, including target font binaries:

$ make cleanall

Because font.ufo instances are committed into the repository, they are not removed on make clean. If that is necessary, run:

$ make cleaninstances

Note also that font.ttf instances stored in the repository are not generated entirely automatically. These TrueType versions of the instances are produced in a process that depends on manual workflow described in detail by Frank Grießhammer. Because of that, make will build the target TTFs only if it finds those files already in place.
