Have you tried this Kernkraft Wiki?
It could get you started. However, I wrote that years ago and never found time to work on it since then.
Let me know if you have more questions.

hi mark

thanks for getting back to me…

i worked it out.

you need to put it in the folder scripts folder (scripts folder)

than under windows menu,go to plugins menu and install

then go to “glyph”, and scroll down… there it is!

as you can see i am a total non coder… non techie.

but i have it installed now, am using it… its great.

i really needed to know how to kern all the fonts i have designed, as i am teaching others to use glyphs and this was a total stumbling block.

Not sure about that. I expected you just install it via the Plugin Manager. No Scripts Folder needed.

You don’t need Kernkraft at all to kern fonts. It just helps you along the way, especially with large glyph sets.

hi again Mark


i know you don’t need it. but it does make things much faster. i really like it. now my font finally has all the tricky pairings kerned… I had a lot of trouble with metrics machine … as i am busy, and need to be across alot of areas… so need solutions that are easy to implement.

I think you should charge for it… metrics machine cost me $100 and i can’t even use it!


Thank you for the motivational reply, I really appreciate it.

Charging is a topic of its own, I am still happy to provide free tools whenever they didn’t cost my too much time and basically were developed along my personal workflows. Recently my tools got more and more complex and need constant updating along with GlyphsApp updates and user requests, so those happen to be commercial plugins. Kernkraft in particular has been commissioned and funded by @bBox_Type back then to be open source. :slight_smile:
