I have a jEdit BeanShell macro that runs my Markdown files through Maruku when I save them:
if (buffer.getMode().toString().equals("markdown")) {
cmd = "C:\\Ruby\\bin\\maruku.bat -o " + buffer.getDirectory() + buffer.getName().replaceAll("markdown$", "html") + " " + buffer.getPath();
exec(cmd);
}
This works great when the Markdown file is valid. But if I've made a mistake, jEdit just waits around forever for the exec() call to "succeed," which it never will. When this happens, I have to kill jEdit's javaw.exe process and run Maruku manually from the command line to discover the error, e.g.:
E:\bp\plan\supply_chain>maruku business_plan.markdown

Not creating a link for ref_id = "17".
Then I restart jEdit, fix the error, and re-save the file, at which point the macro succeeds.
How can I make my macro more resilient to either die helpfully (display Maruku's error output) or, at the very least, die silently so I don't have to kill jEdit?
