[TxMt] Re: R bundle: find variables in object

[Tim Bates]

Getting this going in textmate would be awesome!
It’s great in R.app to be able to tab and get deeper and deeper into complex objects…

To do this in Textmate, you don't want to scan the source: the object names are not necessarily exposed there

What would be needed is a command that when it gets 

object$→

would call names(object) and return that completion list (via applescript, I think is the only API)

likewise
object@→ calls slotNames(object)

Something like this might also give you a head start…

It’s for function completion (which i have switched off in the default R.bundle because it’s too laggy)

Getting a non-laggy version of function parameter completion would rock!

What language could I use to scan the source? Could you give some
indications of what code should look like and where it should be placed

Not without writing code to scan your source and produce a list of the
variables contained in the object.

Though if you have code to do this, setting up tab to insert that as a
completion list (snippet) when tab is pressed and is to the right of an
object is fairly simple.
