Code Mirror is a great addition to MODx Revolution that serves as a very useful EditArea replacement. Code Mirror is used for showing parser/syntax errors and highlighting code as the programmer works on the code.
I still don’t recommend using the EditArea for anything but an extremely quick fix, but it definitely changes the dynamic of the EditArea for the better. In my opinion, I believe that until MODx has some sort of revision control/ source control management it is probably a better idea to use svn or git and then copy and paste final changes to the production db.
Readers, what do you think and do you have any other EditArea replacements that are better? Recommendations for Revision Control?
