Dear all

After upgrading my OS to SuSE Linux 7.1 (intel) and re-compiling R
1.3.0, I noticed that the arrow keys are not working anymore. Not even
emacs-type commands (such as Ctrl-a or Ctrl-e) work anymore. However
"readline" and the arrow keys seem to be working well outside R. Can
anyone tell me what may be wrong?

Instead of "re-compiling" you must "re-configure from scratch" after an OS
upgrade.
I.e.,
	rm config.cache
	{path/}configure
	make
etc

An even more foolproof (but considerably slower) version of the above would
be to throw away your 1.3.0 installation, and re configure from scratch.
This means that if your build directory is = source, you trash everything,
unpack the tar file again, etc.

SuSE Linux 7.2 (from CRAN) instead of building from source.

Thank you very much for your support

Sounds like you may have lost the header files for readline in the
upgrade. Look for an RPM named readline-devel or so.

Otherwise, check the output from configure to see what it has to say
about readline. (Remove config.cache first).

Hi, having run into this problem (R's configure not picking up my readline
lib) myself a couple times, I'm wondering whether the 'readline feature'
could be added to the capabilities so that I could do:
just like I can do today:
tcltk
 TRUE

?

It could, but it's a Unix-specific feature, and the idea of
capabilities() was to have a programatic way to use certain features
if they existed (or not if they did not), so this was not an obvious one.

Perhaps a neutral name like "command-line editing"?  Any ideas for a
shorter name?

You could make it really short, like "cli":

     cli: is the command line interactive (with editing and
          history mechanisms)?

or

     cli: is the command line interactive with (emacs- or vi-
          style) editing and command history?

Um, cli is "command line interface" (opposite of GUI). "cledit"?
