How to delete text after the 2nd specific character in each row

Hi, @crimson-virtuoso, @alan-kilborn, @ekopalypse and All,

Alan, very informative post, indeed ! So, If I correctly understand what you said, this means that :

If the test, on present line 1816 of the FindReplaceDlg.cpp file, for a possible change of selection range, would have been absent, the \K regex feature would work, while doing a single replace operation, with the Replace button ?

I backup your post’s link for future reference, if any question regarding the weird behavior of the \K feature ;-))

Best Regards,

Well, it wouldn’t be as simple as removing the indicated line, as that would break other functionality.
Truly, though, I haven’t thought too much about it.
While I can kinda read C++, and I can use the Visual Studio debugger to step through its code, it isn’t my strong suit.
Hmm, maybe I don’t have a “strong suit”. (Is that a known expression?)
I leave it to others, but I’m fairly confident in my analysis presented earlier about this; I spent a bit of time single-stepping through it and looking at it.

You can use find to jump through the matches but you cannot use
replace while doing this.

I can’t think of any better.
It would be better to replace “^” with “\A”.

^((\w+ \| ){2})(.+)
\1

Why do you think so? What is the advantage of using \A instead of ^ in this case?

If I wanted to swap lines one by one
the pattern works from the cursor position.

the pattern works from the cursor position.

that is correct but this means also that it can match the wrong parts.
Assume the following ( | this should be the caret)

string1 | stri|ng2 | string3 | string5744

in that case it would handle string5744 as the match and NOT string3 | string5744

string1 | string2 | string3 | string5744
string4001 | string2668 | string1234 | string496
string201 | string202 | string203 | string489

in this example there are 3 x |

I’m sorry, but I think I’m out.
If you think you’re gonna get anywhere with the way you communicate, good luck with that.
I won’t waste any more time trying to figure out what you might mean.

^((\w+ \| ){2})(.+)

can be replaced individually
