How do I merge two or more consecutive lines into one?



  • Hello,
    Is it possible to merge

    table TAB tisch
    table TAB tabelle

    into

    table TAB tisch, tabelle

    The word order on the right hand side of the TAB is not important: “tisch, tabelle” , “tabelle, tisch”. All words are lowercase. There may be more than one words on the both hand sides (e.g. security guard TAB wachman).

    Thanks in advance!



  • I would do a Replace (ctrl + H) with the extended option on, and replace this: \r\ntable TAB with a comma or the separator you want.



  • Thank you for your reply, Frank!

    At first I thought the “table” in your formula is a kind of function word, but it is not.

    Basically I need a regex expression or a Notepad++ function or a combination of both that will perform the following expression: (I hope I can express: ) )

    “If the text up to the tab (\t) in a line is the same as the text(s) up to the tab(s) in the consecutive line(s), keep one occurrence of them and merge everything on the right hand sides of the tabs in the consecutive lines in question.”

    Another example (and by “TAB” I mean “\t”):

    Before:
    Line 344: bördelversuch TAB flanging test
    Line 345: bördelversuch TAB folding test

    Line 28872: führungszapfen TAB guide pilot
    Line 28873: führungszapfen TAB guide pin
    Line 28874: führungszapfen TAB pilot pin

    Line 659368: horizontal geteilt TAB horizontally divided
    Line 659369: horizontal geteilt TAB horizontally split

    After:
    Line 344: bördelversuch TAB flanging test, folding test

    Line 28872: führungszapfen TAB guide pilot, guide pin, pilot pin

    Line 659368: horizontal geteilt TAB horizontally divided, horizontally split

    Maybe you could extend and generalize your formula accordingly?

    Thanks again!



  • use a regex, compare 2 sentences, and add all new words on the last of the first sentence.



  • Hello glossar,

    Once again, regexes can do miracles :-)) Just follow these few steps , below :

    • Move back to the very beginning of your file ( Ctrl + Origin )

    • Open the Replace dialog ( Ctrl + H )

    • In the Find what zone, type the regex (?-s)^((.+\t).+)\R\2(.+)

    • In the Replace with zone, type the regex \1, \3 , with a space character, after the comma symbol

    • Uncheck, preferably, the Wrap around option

    • Select, of course, the Regular expression search mode

    • Click on the Replace All button, SEVERAL times, till the message Replace All: 0 occurrences were replaced is displayed, in blue, at the bottom of the Replace dialog

    REMARK :

    • This means that if, in your file, the maximum of consecutive lines with identical contents till the tabulation character, are N, you’ll have to hit N times, on the Replace All button, to get all the work done !

    • Don’t forget that the caret does NOT move during the Replace All operation. So, it should stay stuck to the very beginning of your file !


    NOTES :

    • As usual, the in-line modifier (?-s) ensures you that the dot meta-character will match standard characters, only, even if you previously checked the . matches newline option !

    • Then, the regex engine looks, from beginning of line (^ ) for :

      • Any non-null range of characters ( .+ ), followed by :

      • A tabulation character ( \t ), followed by :

      • Any other non-null range of characters ( .+ ), followed by :

      • Any kind of EOL characters ( \R ), followed by :

      • The group 2, which is ( .+\t ), that is to say, the SAME range of text, between beginning of line and the tabulation included, than in the previous line, and, finally, followed by :

      • Any other non-null range of characters ( .+ ), without line-break, stored as the group 3

    • Now, in replacement, we rewrite :

      • The group 1, whose contents are (.+\t).+. That is to say, all the contents of the first line, without its line-break, followed by :

      • A comma and a space characters

      • The group 3, which represents the part of text, after the tabulation character, in the second line

    It’s not very difficult to understand that, as we, always, rewrite, first, all the contents of a line, followed by the second part of the next line, this process is cumulative on any amount of lines, whose part, before the tabulation character, are identical !

    Hope that this S/R may helps you, Glossar !

    Best Regards,

    (?-s)^((.+\t).+)\R\2(.+)

    hello Guy38, something is wrong on this formula. Get an error: “Cannot find the text (?-s)^((.+\t).+)\R\2(.+)”



  • Hi, glossar and Vasile,

    Hum… Very strange ! As for me, it works quite fine ! So, Vasile, let’s recapitulate :

    • glossar, from your original text, below :

      Line 344: bördelversuch TAB flanging test
      Line 345: bördelversuch TAB folding test

      Line 28872: führungszapfen TAB guide pilot
      Line 28873: führungszapfen TAB guide pin
      Line 28874: führungszapfen TAB pilot pin

      Line 659368: horizontal geteilt TAB horizontally divided
      Line 659369: horizontal geteilt TAB horizontally split

    • And, taking in account that :

      • The string TAB, with a space character before and after, refers to a single tabulation character \t , of code \x09

      • The part line number #####:, that begins each line, for information, must be deleted

    We, finally, get the text, to work on :

    bördelversuch	flanging test
    bördelversuch	folding test
    
    führungszapfen	guide pilot
    führungszapfen	guide pin
    führungszapfen	pilot pin
    
    horizontal geteilt	horizontally divided
    horizontal geteilt	horizontally split
    

    Now,

    • Move back the caret before the first line

    • Open the Replace dialog ( Ctrl + H )

    • In the Find what zone, type the regex (?-s)^((.+\t).+)\R\2(.+)

    • In the Replace with zone, type the regex \1, \3 , with a SPACE character, after the comma symbol

    • Select the Regular expression search mode

    • Uncheck all the other options

    • Click THREE times, on the Replace All button, till the message Replace All: 0 occurrences were replaced is displayed, in blue, at the bottom of the Replace dialog

    You should get,as expected, the replaced text, below :

    bördelversuch	flanging test, folding test
    
    führungszapfen	guide pilot, guide pin, pilot pin
    
    horizontal geteilt	horizontally divided, horizontally split
    

    Cheers,

    guy038



  • hello Guy, nope, is not working. Please take a look on this print screen:

    https://snag.gy/6ts5Gy.jpg

    or here

    https://snag.gy/O0ceRV.jpg



  • Guy - You’re the man! :) Thanks a million! It works! I can’t believe it, but it works!

    Thank you!

    By the way, I like the way you write, your writing style, and enjoy reading your posts! :)



  • No, Vasile, it works!

    Here is my screenshot! :)

    https://snag.gy/V6acUA.jpg

    By the way, this “Snaggy” website is cool! Posting a screenshot couldn’t indeed be easier! I have bookmarked it! Thank you! :)

    And finally, I find it a silly practice that new users have to wait for 1200 seconds in order for them to submit their second post!



  • Hello, Vasile,

    Ah, yes ! Quite weird ! From your print screen pictures, everything seems OK : We, both, have the same fields and options and, from the status bar, our encoding and line breaks are also identical !!??

    Moreover, I verified that the Glossar’s text, inserted in your new tab, does have the same displaying than my text ! This implies that you correctly inserted the tabulation characters ( of 4 spaces characters, by default, like me ) !!??

    So, the only thing that could explain the search failure should be, that you, probably, inserted some invisible character(s) in the search regex ?

    But, I must admit that I’m really annoyed to not being able to point out the true reason of your N++'s search behaviour !

    See you later…

    Cheers,

    guy038

    P.S. :

    Glossar, just see your reply to Vasile. Quite pleased that it works as expected, on your configuration !

    BTW, some of us may could test my regex ? May be, it will help us to identify the problem :-)

    One more point, Vasile, which N++ version are you using ?



  • hello. I am using v7.1, no update available.

    But, I had an error yesterday morning, something when N++ had to update Plugin Manager and a Npp plugin, don’t remember very well. I will restart the computer tomorow, and I will test again.



  • no, after restart nothing change. And I installed the v.722, ant still doesn’t work. What a bug is this?



  • @guy038 said:

    Click THREE times, on the Replace All button, till the message Replace All: 0 occurrences were replaced is displayed, in blue, at the bottom of the Replace dialog

    Out of curiosity I tried it, and found that I had to press Replace All only TWO times to get a complete replacement on these three groupings of text. The first press of Replace All does the first and third sets of data; the second press does the second set. However, in the end, it changed the data as expected.



  • Hi, Scott, glossar and vasile,

    Yes, Scott, two times are enough, indeed !. However, I replied to glossar for the general case where you do not know, exactly, what is the maximum of lines with “identical beginnings”, because of a huge file, for instance !

    In that case, it’s better to click on the Replace All button till the message 0 occurrences were replaced appears ! Indeed, as long as yon obtain the message Nocccurrences were replaced, with N > 0, you cannot guess that no more occurrence has to be replaced, the next time :-))

    Cheers,

    guy038



  • @Scott-Sumner

    I press 50 times “Replace all”, and nothing happen. There is a bug somewhere…



  • @Frank-Orellana

    this is working fine !



  • hello guy38, and all friends. Maybe you can improve my regex to resolve the solution (other way).

    So, the regex below will bind (merge) all the sentences into one. The problem is that is not cut the words that repeats.

    Search:
    \s+(.*?)

    Replace with:
    leave space



  • there will be another good solution, that works:

    Find What: ^(\w+\s+\w+\s*)(.*)\n\1
    Replace With: \1\2,
