I wrote the interface between R and TeXmacs. Recently, I added tab completion. However, there is one slight problem. In order to enable easy interaction with R, I (I.e. my program) interact with the command-line interface. This means that the user can invoke demo(), and then R will interact with the user and ask to press enter. It also means that the user can enter a<-c(3,4 and then R will respond with '+'.
The problem is this: the way I implemented tab completion is calling an R function that creates the completion. But, while in the middle of user input, I can't call a function. I guess that ESS for emacs has the same problem. when I enter "a<-c(3,4", and then on the next line try to do tab completion, ESS replies that 'ESS process is not ready. Finish your command before trying again'. Of course while interacting with R on the command line, tab completion does work. So, the question is - is there any way to interrupt the current input to R, call a function, get the return value, and then continue with the input where it was? To do something similar to what pressing 'tab' in R does internally? Something like the equivalent of ctrl-Z for a shell? -- View this message in context: http://r.789695.n4.nabble.com/Is-an-R-sub-session-somehow-possible-tp2530174p2530174.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
