Re: [racket-users] How to break a process created with system
Does `(current-subprocess-custodian-mode 'kill)` combined with Cmd-k (for kill, instead of break) make the subprocess terminate? If so, you could use `dynamic-wind` or catch `exn:break` exceptions, possibly put the subprocess under its own custodian, and so on.

[racket-users] Export indentation preferences in a package's info.rkt?
I find it irritating when I have to repeatedly add various macros exported by libraries to their proper group in the Indenting section of DrRacket's settings so that they're properly formatted. Is there a way for a package's info.rkt to specify default indentation preferences for it's macros for DrRacket to make sense of? If not, would that be something easy enough to do and useful enough to be worth doing? -- You received this message because you are subscribed to the Google Groups Racket Users group.
