[Beta] Bug in MRT using RegExp is still present

[XPEHOPE3KA]

I needed to rename such files as
1_bla.txt
13_blabla.txt
423_blablabla.txt
and so on (less than four digits, numbers are NOT suitable for [C]!!!)

I decided to do it like this (regexp enabled):
Search for: ^(\d\d)_(.*)|^(\d)_(.*)
Replace with: 0$1_$2|00$3_$4
But that doesn't work properly - the | symbol is inserted in the resulting filename, while it normally is for splitting "search for"s and "replace with"s from each other.

I know I can perform the desired renaming in two steps, but why can't I use the | symbol?

[XPEHOPE3KA]

Anybody out there, please confirm that it's impossible to use | symbol together with regular expressions.

[VadiMGP]

Yes, it is impossible to use | in replacement string.
It is allowed in search only.

[XPEHOPE3KA]

But why?
You know, if I have a file "aaabbb.txt", and "search for"=aaa|bbb, and "replace with"=ccc|ddd than I will get cccddd.txt. So I want this with regexps too.
Maybe, regexps have some syntax which doesn't allow |?

That question can probably only answered by @ghisler.

I agree. That should be fixed.

You cannot mix regexp and TC specific search attributes. They are two different engines. The regular expression syntax does not allow pipes in a replacemet expression. AFAIK.

[XPEHOPE3KA]

It doesn't, but Ghisler should take care of that. Now TC parses those two strings without any notice to TC's | when regexp is enabled.
| in regexps stands for "or" in such expression (bla|anotherbla|somethingelse), so it may be a little hard to distinguish where | belongs to regexp and where to TC internal syntax. To avoid this, I guess, the symbol | should be changed to something else in internal syntax.

[majkinetor !]

I agree. That should be fixed.

[XPEHOPE3KA]

Just to keep the topic topmost until Mr. Ghisler comes, maybe let's discuss a possible replacement of |?
BTW, the | can be left as it is, if regexp switch is off, so most users (2m care for newbies) won't notice any difference.
AFAIC, ! can be used, as it's not used in regexps. Double ! will stand for '!'. What do you think?

[XPEHOPE3KA]

Ah, yes. ! can't be used as then this string in "search for" field won't be recognized:
bla.!!!!otherbla.tx!!

But slash / seems to be a good solution. It can't be used neither in filenames nor in regular expressions.

[Flint]

I support the request: replacing of multiple strings should work with regular expressions too. If there are doubts that the users mey become confused, this behaviour may be controlled by an additional wincmd.ini option.

[XPEHOPE3KA]

This bug is still present in TC 6.55pb1.

[ghisler(Author)]

You cannot use the | for multiple strings together with regular expressions. This is not supported, and it's currently not planned either, sorry.

[XPEHOPE3KA]

Why not? It's fixable easily - see the upper postings:

and the next.
