Announcement: (For those every-once-in-a-while occasions when you run R from a terminal instead of Emacs, and then wish something would happen when you hit TAB...)
Last week, I started looking at the GNU Readline documentation to see if I could figure out how to use it for command completion within R. It turned out to be easier than I had expected, and I now have a beta version of the 'rcompletion' package available at http://www.stat.wisc.edu/~deepayan/R/rcompletion_0.0-6.tar.gz >From the help page: Description: This package provides pseudo-intelligent TAB completion for a readline enabled instance of R when it is run from a terminal (or more specifically, an interface which uses readline to accept user input). It has no effect on the various GUI interfaces to R, including ESS and the standard Windows interface. For more details, install and load the package, then type package?rcompletion at the R prompt. Testing and feedback would be appreciated. Feature requests and patches are also welcome, of course. Questions: There are a couple of things about which I would like some advice: (1) The package currently contains a very rudimentary configure script which stops installation when readline is not found. I'm not sure if this is portable enough. .../src/unix/sys-std.c has more sophisticated conditional directives, but I don't know enough about this sort of thing to interpret those. Any thoughts or suggestions on this would be appreciated. (2) What's the recommended procedure to distribute this, given that (a) it's not relevant on Windows (i.e. won't do anything even if it could be installed) and (b) may or may not be relevant on Macs, some of which apparently have a fake readline that doesn't support completion? -Deepayan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
