Case #18537

Customer is having trouble with code completion in MonoDevelop At first it would only update to reflect only changes after customer restarted, but currently it isn't updating. 

Also, the directory '~/.config/MonoDevelop' does not exist on the customer's MacBook Pro machine.

Received the following:
my_username1:.config my_username$ pwd
my_username1:.config my_username$ ls
gtk-2.0 inkscape menus stetic xbuild
my_username1:.config my_username$ rm -r ~/.config/MonoDevelop/CodeCompletionData
rm: /Users/my_username/.config/MonoDevelop/CodeCompletionData: No such file or directory

Attempted to re-install MonoDevelop, but did not help. The syntax highlighting is incorrect for types in the referenced MonoTouch Binding Project. 

They are running Mac OS X Version 10.7.5

MD has not used a ~/.config directory on Mac/Windows since version 2.4. In MD 3.0, the code completion cache directory is ~/Library/Caches/MonoDevelop-3.0/DerivedData

What code completion is broken? Is it just for referenced binding projects?
Comment 2 Isaac.Eckert 2012-10-16 17:55:48 UTC
MonoTouch has a feature to bind to an Objective-C library using a MonoTouch Binding Project.  The project generates hidden *.g.cs files containing proxy objects from supplied metadata.  The result of building this project is an assembly that contains  proxy classes for accessing the associated Objective-C libraries from C#.  The assembly can be opened in object browser and nothing appears unusual.

So, none of the proxy classes are recognized by the syntax highlighter or code completion for some reason.  There is no indication that the proxy classes exist.  However, everything compiles just fine and the proxy classes call Objective-C code without any issues.

At first I thought this was a general issue since syntax highlighting has been a little slow and sometimes required a restart.  Now, I see that it is occurring exclusively for the proxy types after several restarts and installs.

The good news is that we've a fix - the bad that it'll take some time to release it :/

I backported the fix to the 3.0.x series.
