A lot of "lightweight" non-IDE development environments for embedded 
systems tend not to provide this, particularly if you're using some 
form of cross compiler/cross assembler.  Sometimes, you're thankful 
that you have a compiler at all, much less whether it happens to be 
well integrated with an editor.

And, of course, "open source and trivially ported" still means 
there's non-zero work in getting it working.
