Plugin SDK

This is the Plugin SDK for the Glyphs font editor. There are various kinds of plugins (see below), and there are two ways of writing them, in ObjectiveC or in Python. You will find extensive documentation in the readme files and the code comments. But do start with the tutorial. Then, continue with the file inside the respective template subfolder.


These plugins add additional file formats for the export dialog.


These are plugins that add functionality in the Filter submenu of Glyphs. A filter can either have a GUI (dialog window) or none. A filter can also be called as an instance custom parameter.


These plugins add new sections to the Palette (Window > Palette, Cmd-Opt-P).


These are all plugins that do not fit any other category.


These plugins add extra View functionality. They usually draw additional items in the current Edit View. Their titles, preceded by ‘Show’ will appear at the bottom of the View menu of the application.


These plugins add a new tool in the toolbar. You can place a small PDF as toolbar icon in the Contents/Resources/ folder. For measurements, take a look at the placeholder image that is already there.

File Format Description

The file contains a description of the Glyphs 1.x file format.
