bookmark only on even lines of a list?

I’m not on a PC as it’s late here, but here is a possible solution which is achievable for someone with limited regex experience.

As you say a list, that presumes it is part of a file rather than all lines, although my idea works for both.

Select the lines if some of the file or put cursor in first position of file if all lines.
Use the column editor to insert numbers, starting with 1, increase by 1, and set repeat to 1 (might need to be 2 , I haven’t used this option). No need to have leading zeroes but we do want each number listed twice.
Create a regex which looks at a number and also the one on the next line. If both the same then delete the one on the odd line, which is most likely the first one.
Once every 2nd number removed, use the bookmark feature to mark the (even) lines which have a number at the start.
Remove the numbers at the start of the line.

Hi, @cisco779k, @astrosofista, @alan-kilborn, @peterjones, @terry-r and All,

EDIT : In this post, I’m answering, specifically, to the @cisco779k’s question : how to delete even lines in a list?

Ah ! Interesting problem ! Here is a nice regex solution :

SEARCH (?-s)(.*\R).*\R?

REPLACE \1

IMPORTANT :

The current line, even empty, becomes, by default, the virtual line 1, whatever the cursor location. So :
- This virtual line 1 is kept
- The virtual line 2 is deleted
- The virtual line 3 is kept

and so on…

By default, the regex S/R processes all lines till the very end of current file
If you want to restrict to a specific range of lines, simply use the In selection option of the Replace dialog
Beware to not perform this regex S/R, using the Find in Files search tab or using the Replace in All Opened Documents button ;-)
True empty lines are considered as valid lines, too !
You may record this regex S/R as a macro

Test this regex S/R against that list of features and bug-fixes of the v7.9.1 change.log file !

1.  Fix NUL file-corruption bug after Windows shutdown brutally (Fix #6133).

how can i put a bookmark only on even lines of a list?

I would do it this way:

This will put red marking on the text for the first character in even lines. If you don’t like that, untick Bookmark line and press the Clear all marks button.

can i put a bookmark only on specific ranges of lines?

Yes, use In selection checkbox rather than Wrap around for this. However, note that the notion of “even” will be from the point where you start the selection, NOT the absolute line numbering.

Guy, maybe you should edit your post above to say that THIS regex solves THIS problem requested by the OP:

how to delete even lines in a list?

Because the OP asked for 3 things in one posting, it is (slightly) confusing which one you are addressing.

@Terry-R
thank you for your support, but my problem persists at point 3 of your help (create a specific regex)…

@guy038
thank you for your regex. wonderfull, like all your regex!

@Alan-Kilborn
your contribution is also very interesting. something that can also be useful on other occasions and not only for this specific case.
thank you for your useful information.

so, people like you who know a lot about np++ help someone like me understand many aspects still unclear about this wonderful (and complex) program.
A DUTIFUL AND HEARTFELT THANKS TO ALL THOSE WHO HAVE CONTRIBUTED TO THIS LONG POST (in the hope that it can also help other users who, like me, do not have all your knowledge about it).
