It has been tough, it’s not at all finished, but here we are, we’ve plugged Fontmatrix into Python. Or the reverse, who knows?
The plan is now to first expose completely FontItem, which is the internal representation of a font, and the database wrapper. While it’s technically almost done, it’s now a matter of documenting the whole thing and let users play with it.
For Fontmatrix itself I have two ideas about the "scripter", one is to replace the fontbook generation from its actual, over complex template based mechanism, with full pythonised code which will increase possibilities and make it more contributor-friendly. The other is rather fuzzy at the moment, it’s around the use of FontTools in Fontmatrix itself.
