Absolutely - Have you looked into Robofog?

*deleted post.

thanks! I am trying to get it working now in Glyphs. the pen tool looks very interesting

Jared - are you referring to Robofog the dead extension of fontographer or Robofab?

Can anyone elaborate on the differences between the two? A lot of the links are dead....
*edit - I'm interested in the differences between the scripting side of Robofog and The Robofab library/modules

very promising stuff!
wish list - colour preview a'la fontlab metrics window
a broadnib pen tool
a plugin that can calculate the black and white areas of each glyph (+counters).

any others to add?

Or in fact Robofont?

Robofont has a number of third-party plugins and—not to toot my own horn—a plugin that I wrote to install them: http://robofontmechanic.com

Scripting has been a part of digital type design for a long time, the new wave editors are both modular to different degrees.

A different question is when we'll get graphic design tools that work this way…

a broadnib pen tool

Yes, definitely!

a plugin that can calculate the black and white areas of each glyph (+counters).

Yes, and it should be possible to restrict the area for that calculation to the x-height, capital height, figure height, small cap height, any other height …

@Jack: Thanks so much, Mechanic rocks! What would I do without it…
