I do like the second form better, especially since the actual code being
run is not obscured by simply being the last argument to a long log
function.

Nice, I'll be following this with interest! What are the pros and cons of
developing a new syntax highlighting format from scratch, versus e.g.
parsing and reusing the kate style files? For the latter route this haskell
package is a good source of inspiration:
https://hackage.haskell.org/package/sk
One helpful thing to do is expand the GUI section of awesome-racket

I just sent them a PR for GUI-helpers.

I'd like to set up a project so that I can check out its git repo, call a
single raco command, and have it install all the packages it needs, compile
executables, and finally invoke raco distribute and generate a single
binary. I've gone through the docs for raco setup but it seems to be geared

I have the following code, which in sequence calls the load-file dialog,
loads the file, processes it and populates a textbox:

Is there a good way to call out to the indentation code drracket uses from
within vim? even just manually piping the whole file through an indenter
would be fine.

I've googled around a lot but couldn't find anything. I would like racket
to be the main program, and consume a C++ library so I can play with it

I don't know about scheme being racket; both chicken and gambit seem to
have reasonably active communities.
I was also surprised at the 16k hits for pony, which has essentially no
ecosystem yet. but actually doing the google search it seems like there's
tons of noise in there.

I was looking through http://en.wikipedia.org/wiki/User:LucasVB/Gallery

and wondered if anyone was doing similar stuff in racket. I'd love to see
code samples if so.
