bug#7475: I wish query-replace-regexp would use perl regexps

[jidanni]

I wish query-replace-regexp would use perl regexps.
It is already hard enough to get the region and regexp right, and then
one has to think 'how do I write that in old fashioned regexp language."
Why can't it be rigged up to just send it to the current perl on the machine.
As it is I am already just saying forget it and 'outsourcing' more
complicated jobs to batch scripts.

Sending every regular expression to an external executable would add a
new dependency and likely affect performance badly.

To do this reasonably would presumably require significant work on the
regular expression engine, and a good plan for making the change.  Many
users are very used to the current regular expressions Emacs use.

Maybe a better option is to develop something like this as an external
package?

I would suggest to close this as wontfix.

All I know is GNU grep has a -P option, to use perl expressions, all
within the same program.

There is a package which does this:

There has been some talk about allowing alternate Perl regexps, but it
wouldn't be just for a single command like this, so I'm closing this bug
report.
