Making Progress on the Console

Making some progress on the GUI's Console implementation. You can see that we now indicate WHICH server we're talking to at the moment. I've added an attached "workspace" inspector in the form of a source list such as the ones you see in Mail and iTunes. This holds information about the objects for inspection or dragging and dropping between servers. The thin black line is a splitter bar and is user selectable (double clicking collapses it entirely).

Both sides now have a status bar (of course I made sure the shading matched the action button... why do you ask?) with an action menu. As well, the hint is back and is now being powered from a new object inspection infrastructure in RExecServer (I have some other code to work on, but I will hopefully mind a few minutes to finish things and do a git push). We're now parsing out the function information rather than capturing string output so I think we can do completion in the style of Xcode or TextMate where, say, lm completion would result in:

lm(<#formula>,<#data>,<#subset>,<#weights>,<#na.action>)

I think Ctrl-/ should advance and that TAB (perhaps, I'm open to suggestion) should complete the editing. In other words, imagine we had...

lm(X ~ Y,mydata,<#subset>,<#weights>,<#na.action>)

then TAB would clean the other three arguments and jump us out of the function. You can't see it, but the console is actually doing a lot of invisible markup that we can use to detect the completion regions. We're presently also using text attributes to track input, prompt, error and output regions. This means we can easily cut and paste text WITHOUT prompts (which has been a major feature requests) and without ambiguity. We can also save a console script as a sourceable .R file for later use (sort of like dribble) saving the previous output as comments or not as all.
