`rgrep' not working

`rgrep' not working

[Massimo Gengarelli]

Dears,

I'm actually using `GNU Emacs 25.0.50.1 (x86_64-apple-darwin14.0.0, NS
appkit-1343.16 Version 10.10.1 (Build 14B23)) of 2014-11-23 on
napi.home' on Mac OS X (Yosemite) and I am having a little issue with
the `rgrep' command which is not working.

Everytime I try to run it, I receive a weird error like:
`Symbol's function definition is void: \,'

Please note that `grep-find', `lgrep' and `ag' are all working properly.
I am not using any weird plugin for grep, and the issue is reproducible
even without loading my init.el file (i.e., running emacs -Q).

Since I'm quite a newbie with Emacs, could you please help me in
debugging?  I thought that rgrep was an user-friendly version of
`grep-find', but I think I was wrong since the latter is working. :-)

I also tried the following:

> C-h f rgrep
> With C-u prefix, you can edit the constructed shell command line
> before it is executed.
> With two C-u prefixes, directly edit and run `grep-find-command'.

But apparently the issue is at an higher level as I am not able to edit
the constructed shell command line.  The two C-u prefixes are working
fine though.

Is there something I am missing?

Thanks and regards,

It's a bug and it was fixed several days ago:
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19171>.

Thanks a lot !
I should have tried the latest sources before sending the message :-)

What input do you give it? (When the prompt says
"Search for (something): ", what do you type before
you hit RET?)

If you provide us with more information, we'll try to
reproduce it as well :)

I don't think that is it. `rgrep' has another
interface. The "r" is either "recursive" or, more
likely, "regular expression" or "regexp" as it is
called in the help for rgrep. Which I think is the key
to your problem, because you probably gave it some
strange input which isn't interpreted literally.

Meta: It is a good idea to find some other way to
quote arbitrary material, because that which you just
used will be interpreted as a citation from a previous
poster and by some clients even hidden by default.

I think so: again, what input do you give it? I think
if you tell us that the problem will be instantly
solved :)
