Hi, This isn't actually a problem with racket, but just a helpful tip for OS X user who want to use the racket system commands for exectables they have installed themselves. (I found it looking at the documentation for an OS X GIT tool)
My problem was I couldn't get (system command) to call newly installed
executables.
- adding it to the $PATH doesn't work for OSX (I believe it does work for
windows, though I don't know the situation on linux?)
The attached script adds the path /usr/local/fossil/bin to the
~/.MacOSX/environment.plist, making the executables in that folder
available to DrRacket, as demonstrated by the keybinding.rkt
user-defined-keybindings file attached as a demonstration/test.
User defined keybindings are a excellent way to extend DrRacket, and this
little tip should help any OS X users who want to use them with their own
tools. (git?)
Cheers,
Stephen
