This is good to hear about, because I'm actually in the middle of
writing something that it will help with. Thanks, Robby.

There are two solutions I can think of:
(1) derive combo-field% and override the on-popup method to construct the
choice menu dynamically based on what is selected in the combo box field.
This has a few disadvantages, namely (a) you have to produce the menu
immediately, so if you have to query
This is what struct/dc is for. Let me know if the docs let you down!

I did exactly this, but for Pollen. You will want to create a new

You need -emacs because coqtop alone won’t distinguish the message panel

Does anyone have work adapting or hi-jacking scribble/examples to run code from

Interesting. Thanks, Greg.

I have noticed that some fonts I used to use became inaccessible on Mac
OS in v7.0, which is when we upgraded Pango. In my case, the relevant
change seems to be that Pango became better at tracking which Mac OS
faces are condensed, and it insists on condensed or not matching
exactly when you reques

I often prefer writing non-trivial SQL as s-expressions (using Ryan's
`sql` package).
I feel the same way about non-trivial regular expressions, and often
use the `rx` macro in Emacs Lisp.
In Racket, I tend not to write super complicated regular expressions.
For example, I started to write a mar
