In a future version of Alkalami, we plan to split Alkalami Regular and Alkalami Light into two separate font families. Alkalami Regular will stay the same. Alkalami Light will become Ruwudu Regular. Future versions of this font will remove non Unicode compliant solutions.

Welcome font developers!

We welcome other developers who wish to get involved in supporting and enhancing this font.

Permissions granted by the OFL

SIL’s fonts are licensed according to the terms of the SIL Open Font License. The OFL allows the fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. For details see the OFL.txt and OFL-FAQ.txt files in the package.

Building the fonts from source code

The latest source files are available in a Github project.

Font sources are in the UFO3 format with font family structures defined using designspace. OpenType source code is stored in the .fea format in the UFO (features.fea) but is maintained in a separate file using the more efficient and powerful .feax format.

The fonts are built using a completely free and open source workflow using industry-standard tools (fonttools), a package of custom python scripts (pysilfont), and a build and packaging system (Smith). The whole system is available in a preconfigured virtual machine using VirtualBox and Vagrant.

Full instructions for setting up the tools and building SIL fonts are available on a dedicated web site: SIL Font Development Notes.

Contributing to the project

We warmly welcome contributions to the fonts, such as new glyphs, enhanced smart font code, or bug fixes. The brief overview of contributing changes is a good place to begin. The next step is to contact us by responding to an existing issue or creating an issue in the Github repository and expressing your interest. We can then work together to plan and integrate your contributions.

To enable us to accept contributions in a way that honors your contribution and respects your copyright while preserving long-term flexibility for open source licensing, you would also need to agree to the SIL International Contributor License Agreement for Font Software (v1.0) prior to sending us your contribution.
