query-replace-regexp interactive replacement string

[suvayu ali]

Hi Emacs users,

I wanted to replace interactively all numbers in the text of an org-mode
document with the number in words, so I tried:

`C-M-% [0-9]+ RET \? RET'

But this gives me an error like this:

> Debugger entered--Lisp error: (error "Invalid use of `\\' in replacement text")
> replace-match("\\?" t nil #("2" 0 1 (fontified t)) nil)
> match-substitute-replacement("\\?" t nil)
> perform-replace("[0-9]+" "\\?" t t nil nil nil nil nil)
> query-replace-regexp("[0-9]+" "\\?" nil nil nil)
> call-interactively(query-replace-regexp nil nil)
> recursive-edit()
> perform-replace("[0-9]+" "?" t t nil nil nil nil nil)
> query-replace-regexp("[0-9]+" "?" nil nil nil)
> call-interactively(query-replace-regexp nil nil)

Since the doc string of `query-replace-regexp' says the following:

> ...
> In TO-STRING, ...
> `\?' lets you edit the replacement text in the minibuffer
> at the given position for each replacement.
> ...

I am not sure what I did wrong. I am using GNU Emacs 24.0.50.1
(x86_64-unknown-linux-gnu, GTK+ Version 2.22.0)

Thanks for any thoughts.

Open source is the future. It sets us free.

Weird, it doesn't work for me either. However, if I use
M-x replace-regexp it does work. In "(emacs) Regexp Replace" it also
mentions \?.

"If you want to enter part of the replacement string by hand each
time, use `\?' in the replacement string. Each replacement will ask
you to edit the replacement string in the minibuffer, putting point
where the `\?' was."

Thank you for looking into this, I can also confirm that it works for me
with replace-regexp but not query-replace-regexp.

Could it be a bug?

Hi,

can confirm this with

GNU Emacs 23.2.94.1 (i686-pc-linux-gnu, GTK+ Version 2.18.6) of 2011-02-25

Seems worth a bug-report

Thanks

Andreas

I'm by no means an expert on the subject, I didn't even know about the
"\?" feature, but now we're two people confused by the documentation
vs. the behavior. If it's not a functionality bug, it's a
documentation bug. Please file a report.
