Hi. Can anyone tell me how to get vi-style command-line editing in irb,
please.
Thanks

The answer's always "Yes".
Now, what was the question?

I guess you can set up your own inputrc file, since IRB is based on readline, and set "editing-mode" to "vi", I never trtied it, though.

I have a .inputrc with precisely that. ESC-k simply echoes.
I've tried rebuilding from source with:
../configure --with-readline=YES ; make ; make install
,but to no avail.
Is this the right redline option? DO I start irb with a parameter?
Thanks

PS Sorry to followup on y own post, but when I strace the irb binary, all
the references to readline produce an ENOENT error. Readline is on the
box, as I use it from bash (unless its built in?)
Not sure if this is relevant.
Heres part of the strace output:
stat("./readline.rb", 0x7fffffffaad0) = -1 ENOENT (No such file or
directory)
stat("./readline.so", 0x7fffffffaad0) = -1 ENOENT (No such file or
directory)

You need the readline extension - you can get it by going
into the ext/readline subdirectory of the source and doing a
'make ; make install' - though you'll need the C readline library installed too.

Hmmm. make in the ext/readline directory just says "nothing to do".
The target for all or install is simply the Makefile itself:
all install: Makefile
Which I would guess means that the mf is not built properly - but I'm
confused now. configure at the top level has no reference to readline.
UPDATE: in case anyone is intereted!
Thanks, Dick!
What I had to do was to edit ext/Setup, and uncomment the "#readline" line
(by removing the '#'), then at the top level, make install again, et voila,
irb now has vi-style command line editing (and is now much more useful, for
me at least).
I dare say this is documented, but I was too feeble to find it!
Thanks
