Finding repetitions

[Debugger]

How do find links (url) that repeat in a text file (on one line)?

[NotNull]

(http[^\s]*)\s.*\1

(marks from first to last)

- or -

(http[^\s]*)\s(?=.*\1)

(marks first)

EmEmeditor - Both regular expressions do not work.

That's not true!

[Debugger]

That's not true!

You said half-truth, because it works only for your example, but not for my text.
In one line can contain only one URL or several URLs, and no duplicates and text.
I mean repeating links in the whole text file (MULTILINE)
So, the regular expression can not be valid.

Code: Select all

Nie mam szczególnych ambicji literackich. Podczas mojej długiej podróży poznałem wielu niesamowitych, kreatywnych ludzi ze świata kina, teatru, literatury i innych zawodów, z których każdy pozostawił niezatarty ślad w mojej pamięci i miłych wspomnieniach, które czasami chcę dzielić. Wszystko, o czym piszę, jest odzwierciedleniem moich doświadczeń, emocji i stanu psychicznego na pewnym etapie życia. Jeśli moje historie choć trochę dotykają kogoś, to jest to dla mnie wielkie szczęście, w przeciwnym razie przepraszam, a poza tym dziękuję za czas spędzony na moich pismach!

This is what I get in EmEditor:

Unfortunately I can't help you with this topic anyway due to the lack of RegEx knowledge…
Ahh, just seeing that your requirements have changed.

No. Only, in a different way formulated.

Thanks, for testing, @tuska! (have to admit that I didn't ...)

@debugger: If your URL's don't start with http and/or end with a space (\s), you have to adapt the regular expression, of course.
I assumed you would understand that (after gazillion regex questions on this forum).

Original question:

How do find links (url) that repeat in a text file (on one line)?

Changed to:

I mean repeating links in the whole text file (MULTILINE)

How's that NOT a different requirement?

[Debugger]

Addresses do not end with any spaces, each address is on a separate line.
Need to modify the regular expression a little to be found as well:
http://www.
https://www.
www.

(http|https):\/\/[\w\-_]+(\.[\w]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?

But that does not help much, because in this way will not find the repetition of links. Regex must have the appropriate pattern for repetition.

[Debugger]

(http[^\s]*)\s.*\1

(marks from first to last)

- or -

(http[^\s]*)\s(?=.*\1)

(marks first)

The author, the developer, EmEditor told me that:

The regex does not make any senses

Then I suggest you ask your emeditor questions over there from now on, instead of here.

BTW: Did you ask the exact same question? - "How do find links (url) that repeat in a text file (on one line)?".
(No need to answer that, it is a rhetorical question).

[Debugger]

NotNull - I can ask the author, but he will not answer in a very long time, and there is nothing to expect help. Also, I can ask the general users from forum who is in contact with this or that who is familiar with it. Each tip is valuable.


The only thing I could find on GOOGLE search: "find duplicate url"
Only this applies to websites, it has nothing to do with text files, which makes the task difficult.

I have to accept the fact that some duplicates can not be found unless you are a wizard who can do everything. And so most of my issues are not simple. Although in the first place I am looking for similar queries in google search.
