Jon is right. Here’s an explanation why.
Think of `...` as a postfix operator. It repeats what comes before it a certain
number of times. In order for `...` to know how many times to repeat the
previous head template, it looks inside the head template for any attributes
bound at the appropriate
In case anyone else needs this and wasn't looking at that other thread with an

I made a little scribble library to do code highlighting through pygmentize in a
way that supports multiple backend renderers.

I was missing something: a bug in my code.
FYI, I got this working if anyone wants an example of how to patch Scribble's
current render mixin.

Using setup/setup works partially, but it doesn't seem to support package
dependency checking (and the #:pkgs keyword argument isn't documented). I
can't seem to find any programmatic alternative to the --check-pkg-deps and
--unused-pkg-deps flags.

Whenever I change code in my package I switch over to the terminal and
recompile it with `raco setup`. This is slightly tedious and I’d like to be

If the user will choose very frequently (and you want the fastest UX),
and the choices in the database don't change very frequently: It might
be worth experimenting with caching the choices in memory. For
auto-complete I imagine something like a trie, or whatever the latest
hotness might be.

I've created a scribble render mixin to call out to pygmentize for typesetting
certain code elements with a certain style.
However, it seems to me that I can't get scribble to use the mixin without
modifying scribble/run.rkt.
I've tried (via rackunit's require/expose) modifying current-render-mixin
It looks pretty appealing to me as well. Clear, concise, and oriented
around pain points that a common developer would have.

Thanks! Looks pretty helpful to me; at the very least I think I can rip out the
parser and interactive loop.
I've already got something syntax highlighting by calling off to Pygmentize.
Might if I reuse some of that code and put it in a little scribble library?

I will throw out the Julia homepage (https://www.julialang.org) as a good
example of language marketing. Perhaps, though, I find the marketing
effective because it is largely targeted at people like me.

Still having trouble though, can't get struct/dc to work in the way I'd
