Hi Nate, > I suspect that this is because I don't have a major-mode for Groovy installed. No, that's not the problem. This should be easy to fix... we just need to know how to get groovy to read commands from standard input. I.e. how do we do the groovy equivalent of this: ~> echo 'print "bar\n"' | perl bar I haven't figured it out yet. Typically one would use a '-' to represent stdin on the command line. My most promising attempt was this ~> echo 'println "bar";' | groovy -e - org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, script_from_command_line: 1: unexpected token: @ line 1, column 2. 1 error 'script_from_command_line' sounded good there. These don't work ~> echo 'println "bar";' | groovy error: neither -e or filename provided [usage message follows] ~> echo 'println "bar";' | groovy - error: neither -e or filename provided [usage message follows] So if you work out how to do that, then on line 96 of org-babel-groovy.el (org-babel-shell-command-on-region (point-min) (point-max) "groovy" 'current-buffer 'replace) change "groovy" to whatever the correct shell invocation for reading commands from stdin is. There are other solutions (e.g. writing the commands to file, or writing a wrapper script) but it would be preferable not to have to take those routes.
