How to mark lines above marked lines



  • Hi! I am trying to mark all the lines of my csv text that has the value ;2. And I have marked them without regex because I am not used to use regex. Now I want to mark the lines above the lines that I have just marked. Any idea of how can I do it?



  • @Unai-Abrisketa

    in the same way as you did it the first time I guess.
    But I assume that there is a reason why you can’t do it that way,
    so maybe you wanna let us know the reason and more
    importantly, what exactly you mean by marked line.
    Is it a bookmark or is it text mark (using styles)?

  • I guess that you havent understood my question. I want to mark the lines that were immediately above of the ones I marked before. For example If i have the next two lines:

    edit “harry”;1
    set subnet 213.154.12.123 255.255.255.0;2

    I want to mark both of them although the one above has the 1 value that doesnt match with the last bookmark.

    Most likely and I’m still confused

    I want to mark the lines that were immediately above of the ones I marked before.
    That is where my confusion comes from. You state that you have already marked it,
    so why not doing the same with the line above?

    For example If i have the next two lines:

    edit “harry”;1
    set subnet 213.154.12.123 255.255.255.0;2

    I want to mark both of them although the one above has the 1 value that doesnt match with the last bookmark.

    One question which you haven’t answered is whether you did bookmark it or whether you selected the
    text and “marked” it with a different color or you used find dialog to mark or …

  • Hello @unai-abrisketa, @eko-palypse and all,

    Luckily, I did understood your question ;-)) Seemingly, you have a file with some lines containing the string ;2. Of course, you easily succeeded to bookmark ( blue circles ) all these lines. But, you don’t know how to bookmark the line above each line containing ;2., don’t you ?

    Here is my method :

    • Open the Find dialog ( Ctrl + F ) and click on the Mark tab OR use the menu option Search > Mark...

    • In the Find what: zone, type in the regex (?-s)^.+\R(?=.*;2)|\G.+ OR the regex (?-s)^.+\R(?=.*;2)|^.*;2.*

    • Tick, both, the options Bookmark line and Purge for each search

    • Tick, preferably, the Wrap around option, too

    • Select the Regular expression search mode ( IMPORTANT )

    • Click ONCE, on the Replace All button

    => In one go :

    • All the lines, containing the ;2 string, are bookmarked

    • All lines, above a line containing ;2, are, also, bookmarked !

    Et voilà :-))

    So, from the initial sample text, below :

        This is
        bla bla
        edit “harry”;1
        set subnet 213.154.12.123 255.255.255.0;2
        bla bla
    	bla blah
    	bla
    	small test
    	set subnet 213.154.12.123 255.255.255.0;2
    	set subnet 213.154.12.123 255.255.255.0;2
        to
    	bla bla
    	blah blah
    	verify
    	set subnet 213.154.12.123 255.255.255.0;2
        if the
    	blah
    	bla bla
        set subnet 213.154.12.123 255.255.255.0;2
        regex works
        set subnet 213.154.12.123 255.255.255.0;2
        correctly
    	bla bla bla ...
    

    We’ll get the 11 bookmarked lines, with the mark :

        This is
        bla bla
    •   edit “harry”;1
    •   set subnet 213.154.12.123 255.255.255.0;2
        bla bla
        bla blah
        bla
    •   small test
    •   set subnet 213.154.12.123 255.255.255.0;2
    •   set subnet 213.154.12.123 255.255.255.0;2
        to
        bla bla
        blah blah
    •   verify
    •   set subnet 213.154.12.123 255.255.255.0;2
        if the
        blah
    •   bla bla
    •   set subnet 213.154.12.123 255.255.255.0;2
    •   regex works
    •   set subnet 213.154.12.123 255.255.255.0;2
        correctly
        bla bla bla ...
    

    Note that if two consecutive lines contain the ;2 string, the are both bookmarked, as expected


    I’m about to post some other regexes, which can bookmark, several consecutive lines of a file, when one of these lines contains a specific string ;-))

    Did you actually do this? If so, I haven’t been able to find that posting.



  • Hello, @Scott-sumner and All,

    When I said “I’m about to…”, I was a bit pretentious ! I haven’t had time to look at, yet ! And this week-end, I’ll be with family, too ! So rather, during next week ;-))

    Have a nice week-end, too !

    Cheers,

  • Hello, @scottsumner and All,

    As promised, here is, below, a list of regexes in order to mark a line that satisfies a criterion as well as one or two lines, either, before and/or after that line ;-)). By criteria, I mean, either, a char, a string or, even, a regular expression !

    As a convention, in the two tables below, I named this criterion XXX and each line containing this criterion, LINE X

    Remarks :

    • I assume that all lines of text are NON empty lines, as I supposed there’s little interest in bookmarking empty or pseudo/empty lines, anyway !. So, if your list contain blank lines, use, first, the option Edit > Line operations > Remove Empty Lines ( Containing Blank characters )

    • I also assume that two LINE X are separated by some lines. In the Minimum X....X column, of the two tables, I mentioned, for each regex, the minimum number of lines, between two LINE X, which are necessary for correct bookmarking, assuming the hypotheses, in each line

    • The indication > 1 ch., in the last column of the second table, means that any line, located right after a LINE X, must contain, at least, 2 characters for correct bookmarking


    In the first table, below, the different regexes does NOT bookmark any Line X, only the lines around it :

    Just test them ! Note that, regarding bookmarking, some other regexes may work nice, too ;-))

  • @guy038

    Hmmmm…well, the regex approach has exactly one thing going for it: Everything needed is entirely built into Notepad++. Other than that…well, sigh…I understand regex…but my head hurts after that last posting…

    If one is willing to install the Pythonscript plugin and run a script, one could be prompted through the process…and get a nice result. I’d like to show the prompts and the end result, but Imgur is not cooperating at the moment, so I guess I will just have to describe it:

    • Prompt box #1: Enter search string (regular expression is possible but not the default)
    • Prompt box #2: Enter integer number of lines to bookmark before the line where search-string hits
    • Prompt box #3: Enter integer number of lines to bookmark after the line where search-string hits

    That’s it…no limitations or caveats…with the exception that it could be slow on really large files with a lot of hits. I should also add that multi-line searches are possible in regex mode or normal mode (in normal mode use ctrl+Enter to specify line breaks–Enter alone will close the prompt box).

    So here’s the script; I call it BookmarkHitLineWithLinesBeforeAndAfter.py:

    def BHLWLBAA__main():
    
        NPP_BOOKMARK_MARKER_ID_NUMBER = 24  # from N++ source code: MARK_BOOKMARK = 24;
    
        search_str = notepad.prompt('Enter search string\r\n(begin string with (?x) to make it a regex search)', '', '')

  • Hi @scott-sumner, and All,

    Just tried your script ! It works nice and I agree : no possibility of strong headaches, with that script ;-))

    Your script logic is a bit different from mine. With my list of regexes you may decide, inside the range [line -2, line -1, hit line, line +1 line +2] to bookmark, or not, any of these 5 lines

    Of course, due to regex limitations, a greater range does not seem sensible ! Probably, in a Python script, it would be possible to extend that range to, let’s say, a maximum of 5 lines before and 5 lines after, which could be bookmarked, or not, independently

    Cheers,

  • @guy038

    What, no upvote for a script you liked? :-)

    Regarding your comments…yea, it becomes a clunky user interface problem at that point–how to tell the running script exactly what you want in that case. Of course if you have some great ideas about a clean interface to that…



  • So Imgur is being friendly again, so I can now show the steps of running the script…

    Starting the script executing you are presented with this box, to which I have typed in ValueError as the search string (I am searching the file containing the script’s own source code):

    Imgur

    After saying “OK” to the search string box, one is prompted thusly (to which I have answered I want 3 lines before a line with ValueError in it to be bookmarked):

    Imgur

    Similarly, after that one is asked about the “after” lines, to which I have answered “2”:

    Imgur

    At that point the script does the searching and the bookmarking, and the result obtained is as follows (I have boxed the search string to make it easier to see):

    Imgur

    As you can see, the line with the hit is bookmarked, as is the 3 lines immediately before and the 2 lines immediately after.
