Re: [ESS] feature request : completion of available packages name
Thanks to you all ! C-c C-e C-l is quite a time saver indeed ! And running `rc.settings(ipck = TRUE)` does provide the kind of completion I was thinking of. ESS rocks.

HOWEVER: I'm discouraging its use in favor of the completion mechanism below: Very early in ESS history, i.e., the early '90s, we agreed on "The source code is real. The objects are realizations of the source code." etc, e.g., see at http://ess.r-project.org/Manual/ess.html#Philosophies-for-using-ESS_0028S_0029 and in the mean time, with reproducibility and literate programing "every where", you should have been taught to work with *.R (or *.Rnw, *.Rmd, ..) scripts rather than doodling away in the R buffer aka R console. ... which is really what C-c C-e C-l is about. Rather you *do* want the correct require() / library() function calls in your *source* code, right, as I mentioned: "The source code is real ...

In this respect not the least thanks to all the R-side completion work by Deepayan Sarkar!!

Try executing rc.settings(ipck = TRUE) in your R session or .Rprofile and see if it works. It should as long as ESS uses R's completion mechanism. It does require running installed.packages() to create the cache, which can be slow the first time for large/NFS libraries, which is why it's disabled by default. -Deepayan __ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help

[deleted] More seriously: We do something like that already in ESS for quite a while now but I don't recall the details. I suspect Martin knows this, but ... C-c C-e C-l runs ess-load-library. With `ido' enabled, it puts a list in the minibuffer where fuzzy matching will narrow it down to the package one wants. Hitting TAB will display all the package names that fuzzily match in a completion buffer. Thanks for reminding me of the nifty feature!

More seriously: We do something like that already in ESS for quite a while now but I don't recall the details. You also may want to give more details about the kind of completion.. notably as emacs / ESS have quite a few different completion possibilities, as we have been told recently here.

[ESS] feature request : completion of available packages name
Hi, Do you think it would be difficult to add some kind of completion backend to complete the package names when typing `library(` ? I was thinking that the list of packages could be populated by calling something like : names(installed.packages()[,2]) But I don't know enough elisp to implement it myself… Thanks !
