Like I said: I don't think we should support arbitrary
transformations of regular expressions' syntax.  It makes no sense to
me.


And we don't need to support _all_ of the above syntaxes, we could
support just the BRE or just the ERE.

This is a bigger job and is there a current need for it?

People just want to make their life easier and change the way
how the syntax of some of the symbols often used by them works
in interactive input (e.g. grouping).

If we wait for those complete translation functions then we
might have to wait for a long time, unless there are people
who want complete translations right now, but there were no
such volunteers in this thread for that task.

Adding an option for a custom translation function solves the
problem right know, everyone can change the symbols they are
most annoyed by and this function can be the base mechanism
for complete translations later if someone ever wants to do
those.

Then need to wait when someone will step forward to write these
BRE/ERE/PCRE translation functions.

The purpose of regexp translation is that all user facing regexps by
read-regexp should use the translated format, so if there is a need
for a function which converts to the convenient format then the
user should provide that as well. Maybe there should be one function only
with  an argument specifying the direction of the translation.

BTW, ideally the variables you mentioned ('search-default-mode' and
'replace-regexp-function') should be merged with this option, because
it's unlikely the user wants one regexp syntax for one command and a
different syntax for an other one, so there should be a single
translation function which works everywhere where user facing
regexps occur.

If it provides me a more friendly regexp syntax where I don't have to
qoute parens, alternations then I'm OK with it, though I guess
providing a full translation for certain styles is much more work,
so giving an option for translation and letting the user write his
own function according to his taste may be the simpler solution which
can even support different custom regexp styles later.

Before we install something like this, we need to discuss the relevant
use cases and agree that it makes sense for us to support them.

I originally interpreted the OP's request as asking for a feature
where the user could use one of the regexp styles used by other
programs, such as BRE or ERE or maybe PCRE.  If this is indeed the
intent, then I'd rather we implemented support for only those specific
styles (or some subset of them).  It doesn't make sense to me to
support arbitrary translations of regular expressions, because I see
no valid use cases for such a general feature, and am unaware of any
other applications which support regular expressions that allow such
arbitrary translations.

This patch allows using Rx syntax, so for example, after running 'occur',
you can type an Rx expression:

  List lines matching regexp: (rx (or "e.g." "i.e.") " ")

Sorry, I misread your feature request, I thought it's continuation
of adding custom regexp types to search/replace.  You are right
that read-regexp misses support for custom regexp formats.

It's easy to add regexp translation to the return value of read-regexp.
But there is one complication: the default value returned by
read-regexp-defaults-function might be a function like
find-tag-default-as-regexp that returns a regexp in the
default format created by regexp-quote.

Do you agree that a pair of two translation functions should be provided:
one to translate a custom regexp syntax to the default regexp syntax
(to be used on the return value of read-regexp), and another translation
from the default regexp syntax to the custom regexp syntax (to be used
to translate the default regexp value added to the minibuffer)?

Does that option affect every command where read regexp is used?
Because this bug is about that.

So regexp translation for occur, flush/keep-lines, highlight-regexp,
dired-mark-files-regexp, etc., so anywhere where read-regexp is used.

This user option already exists.  It's name is 'search-default-mode'.
For stand-alone query-replace it's called 'replace-regexp-function'.

So we just need someone to write these regexp translation functions.

Suppose, the user wants to use ( ) for capturing and
\( \) for matching parens. He provides a function
which does this translation.

If this new option is set and is a function which does
the translation then read-regexp will

- accept the format which the user prefers, in this case
( ... ) for capturing.

- store regexps in this format in history, so the user
can work with the user's preferred format even when
retrieving history entries.

- return the elisp format regexp by calling the function
provided by the user which does the translation.
