MonoDevelop 1.0 doesn't appear to have a code-formatter like Eclipse does for Java. Is there a preferred shell script (or MonoDevelop add-in?) that you've found to work well?

At the moment, source code formatting in MonoDevelop is marked as a future enhancement:

In the meantime, you may want to check out Artistic Style for C# formatting:

I'm planning to see how this might be wired up as an external tool within MonoDevelop. If I get to that, I will edit my answer with the information. UPDATE: I don't have enough reputation to leave a comment, so I'll make one here: Nice job, Dustin, and patch for MonoDevelop too :-) I wonder how recent the version is that is included with Ubuntu... Either way, I'm glad you found something that works for you.

Awesome -- I just realized AStyle is available in Ubuntu as a package.
I'm able to add "astyle" as an external tool in MonoDevelop, but it barfs when trying to use the variable substitutions. It appears MonoDevelop is not expanding the ${itemPath} like it is supposed to -- perhaps it is quoting it? I'm going to take a look at the source now to see.
Well, I was able to patch MonoDevelop to properly use astyle as an external tool. I'll look for existing bug reports and submit a new bug if necessary along with the patch. Thanks for the idea!

Thanks, Brandon. I submitted a patch to MonoDevelop. The issue with MonoDevelop add-ins is that there is a mono compiler bug that doesn't handle anonymous delegates correctly. (bug report:

The patch/workaround is to just cast the anonymous delegate to the proper delegate type. (bug report & patch:

I'm running with the patched version now and am able to execute AStyle on the current edited document by simply creating a new External Tool setting with the following settings:

TITLE: A_Style (put in underscore to enable hotkeys) COMMAND: astyle ARGUMENTS: ${ItemPath}

Then, just execute it using Tools->AStyle (or ALT-T, S)

It's a nice programming exercise to write your own formatter . I wrote one for C++ , and it was a nice challenge . You could learn a lot by writing it :)
