Bubble layer dictates the kerning, and generally a bubble needs to be larger.Use Make Bubble Layers script to speed up the process. Make a extra layer and name it "bubble" for every layer you want to kern.The essential part is that you have a layer called "bubble" and run BubbleKern script. In that case, delete them and try running the script again. If the script gives me an error, you may have glyphsapp.py or.

Alternatively you can double click the plugin file to install it confirm Confirm the dialog that appears in Glyphs. It will show up under View menu as Show Kern Bubbles.
After installation, you need to restart Glyphs.
The Show Kern Bubbles viewer plugin needs to be installed in ~/Library/Application Support/Glyphs/Plugins folder (if there is none, create one). Installed scripts will appear under Scripts menu. 
If you needed to install modules, you will need to restart Glyphs. You can install them easily from Glyphs (Preferences > Addons > Modules). Make Bubble Layers and BubbleKern require vanilla and robofab modules to display user interface.
Install three scripts in ~/Library/Application Support/Glyphs/Scripts folder.

BubbleKern Manual.pdf Instruction on how to use BubbleKern with more detail than this README. BubbleKern.py The Python script that does the magic. Delete Bubble Layers.py A Python script that deletes bubble layers from selected glyphs. Make Bubble Layers.py A Python script to help you start drawing bubble layers. ShowKernBubbles.glyphsReporter A viewer plugin that shows bubbles in colour. That’s why I leave bubble shapes and pairs to designers. BubbleKern will kern a font for you, but only do the obvious, not do some mysterious calculation in the background (e.g. If your font has 600 glyphs, the maximum number of possible pairs is 600²=360,000 which contains meaningless pairs like %& or some other junk that you won’t enjoy cleaning up.Ī good tool is something the user can control. Don’t worry, there is a script to help you with that.īut why does it not simply look at all possible pairs, every glyph against every other glyph? Because that takes so much time to check, only to create a huge mess. In the example below, it finds the closest distance of 30 units, and kerns by -30.Īs for pairs to kern, a type designer needs to make a checklist for BubbleKern to work with. Then for a given pair, BubbleKern looks at every scan height, finds where bubbles touch each other first, and kerns by the distance. And the temporary dictionary of bubble sidebearings is built for every letter. When asked to kern, first of all BubbleKern scans through each letter to make an approximation of bubble shape so that it’s faster to calculate. Components automatically inherit the bubbles of base glyphs, so you don’t have to draw one for an accented glyph (for letters like Eth or Tbar, you just draw a bubble for the bar). It doesn’t have to be straight segments or single path, and you craw however you want. That’s right, you kern by drawing it!Ī bubble needs to be made as a extra layer in each master, and it has to be named “bubble“. Once you draw bubbles for all letters, BubbleKern automatically kerns the typeface in seconds. that is based on the shape of surrounding outlines you draw, which is called a bubble. BubbleKern is a set of new kerning tools for the Glyphs font editor by Georg Seifert.
