What are extensions?
Extensions are additional software packages which add specialized tools and functionality to RoboFont. They are an essential part of the RoboFont toolkit.
Technically speaking, a RoboFont extension is a macOS package with a
.roboFontExt file extension, built according to the Extension File Specification.
Once installed, extensions integrate seamlessly into the RoboFont interface, adding themselves to existing menus or toolbars.
RoboFont does not try to do everything a font editor could do. We think this approach is problematic and leads to:
- rigid tools, which force users to doing things one way
- cluttered interface, with too many options which confuse users
- bloated, monolithic software which is harder to maintain
RoboFont takes a modular approach: it aims at being a solid and extensible core application, which provides all the basic functionality required for type design and font production work – while also serving as a foundation on top of which others can build their own specialized tools.
Extensions provide users with options. Instead of having a single tool which tries to solve all problems, RoboFont users have access to a flexible infra-structure which enables an ecosystem of specialized tools – built by multiple developers with different needs and different ideas.
