sort file removing duplicates possible?



  • so… another number? amazing!

    I’ve got version 16 which is lite somehow



  • me too - that is actually the latest one available for ubuntu.

  • so the issue is: which result is the correct?



  • Hello, @patrickdrd, and All,

    First of all, I quite pleased to be back on our N++ forum ! Indeed, I was away because of a general failure of my laptop hard drive C:, which, you could imagine, highly annoyed me and needed immediate care :-(((

    So, after more than a week, a software purchase of EaseUS Recovery Wizard to restore my data ( the only one which could identify all my files, although Windows could not see the C: partition ), the fact that my first 32 Gb USB key did not work, either, ( Windows cannot format it !!), the re-install of the system on an other hard-disk, the Services Pack, the .NET versions, the different updates, some software installations and the total re-organization of my data structure, I can, now, close that bloody sub-routine !! ( Just note that, if I haven’t been able to get all my files back, I still had a last general backup, performed on the 04/13/18 )


    Now, @patrickdrd, you said, in a post above :

    guy038 regular expression results in 28109 lines

    So, I download the list, from your link, in a new N++ tab :

    https://easylist.to/easylist/easylist.txt

    Notice that I, personally, found 69889 lines

    Now, without any change on that text, I simply performed a sort with the N++ command Edit > Line Operations > Sort Lines Lexicographically Ascending, on that raw text

    Then, I used the regex S/R, that I spoke in my previous post :

    SEARCH : (?-s)(^.+\R)\1+

    REPLACE : \1

    I obtained a file of 69790 lines => The difference of 99 lines ( the duplicate ones ) were suppressed, almost immediately !

    So, may be, I’m missing something ?

    Cheers,

    guy038



  • I can’t say for sure, is there any tool that can tell us how many the unique lines are?



  • Ok - the difference of the total amount of lines in TextFX /python and regex
    can be explained, the different usage of caseing(not sure if this is the right word).

    Regex search/replace is insensitive whereas python script is sensitive.
    Once we use the same, the result is the same.

    For the provided example list, I assume, insensitive search and deletion is ok
    but for other cases, sensitive search/replaces might be important.

    Btw. I also used sort and uniq command line tools from linux with same results as python and regex.

    Cheers

  • thanks for clarifying, in terms of speed?

    can python script be made to ignore case?

    I want to ignore case and I want it fast (useful for large files) too



  • these are my settings:

    and my version:

  • @patrickdrd

    can python script be made to ignore case?

    yes

    I want to ignore case

    Understood! :-D

    and I want it fast (useful for large files) too

    Ok, so what is “fast”? PS is in general going to be slower than some other methods, but unless you sort “large files”–also not well defined-- constantly why is speed all that important?

    As an example, I took @Claudia-Frank 's PS one-liner above and ran it on the “easylist” data file, and for me it took 3.94 seconds…would that be defined as “fast” or “slow” or…?

    And on the topic of “large” files, when you get too large (which honestly isn’t really big) you get into trouble with Notepad++ itself dealing with the files…



  • @patrickdrd

    yes, with python we could do almost everything :-D

    Is it important to keep the original lines untouched?
    I mean, having two lines like

    Test_line_content
    test_Line_content
    

    could result in either

    test_line_content
    

    or

    Test_line_content
    

    I will post a performance optimized script later today.

    Cheers

    3.94 for a 60k lines file is ok,
    I mean I show much more time needed, if I remember correctly it should be with regular expressions

    sorting is ok too, I want them sorted each time, if that’s what you ask scott

    @claudia, if possible, make them “accent insensitive” too



  • @Patrick

    sorry, don’t know the term “accent insensitive” , what does it mean?
    For example that è is the same as e?

    Can you provide example data (just need a couple of lines) to see if it is working correctly?
    The speed test I will do with the easylist text.

    Cheers
    Claudia



  • I can envision the following specification for a general purpose script (goes beyond what @patrickdrd has asked for):

    • sort lines case sensitive, keep duplicate lines
    • sort lines case sensitive, remove duplicate lines
    • sort lines case sensitive, keep duplicate lines, reverse order on the sort
    • sort lines case sensitive, remove duplicate lines, reverse order on the sort
    • sort lines case insensitive, keep duplicate lines
    • sort lines case insensitive, remove duplicate lines
    • sort lines case insensitive, keep duplicate lines, reverse order on the sort
    • sort lines case insensitive, remove duplicate lines, reverse order on the sort
    • no sort, remove duplicate lines (case sensitive)
    • no sort, remove duplicate lines (case insensitive)

    A selection active when invoking should define:

    • lines to be affected (only those touched by selection vertically); act on all lines if no selection
    • columns to be used as the sort key (if rectangular selection use the selected columns as the sort key; if zero-width rect selection consider the key to start at the selection column out to the end of the variable-length lines)

    Probably I’ve forgotten something important to this “sort” of thing…

    :-D

    yes, exactly that



  • OK - let’s see what we can do.

    Cheers

  • @Scott-Sumner

    …the following spec…

    Hey Scott! You did forget some things! How about when removing duplicates, we need the options to:

    • keep one occurrence of a duplicated line (when sorting)
    • keep no occurrences of a duplicated line (when sorting or not sorting)
    • keep LAST occurrence of a duplicated line (when not sorting)
    • keep FIRST occurrence of a duplicated line (when not sorting)


  • @Scott-Sumner

    ahh - sorry too late - specs already defined for version 1 you need to open a feature request for version 2 :-D

    Cheers
    Claudia



  • You can find the 1st version of the script here.

    In order to make it run there are two requirements, apart from the obvious one that you need to have python script plugin installed, which needs to be full-filled.

    1.) be sue you have either installed the full package or download and unzip the TclTk into the NPP_INSTALL_DIR. Latest releases

    2.) in order to make the “accent insensitive” feature working it is needed to install a python library called unidecode.
    Unzip the .whl package into NPP_INSTALL_DIR\plugins\lib\

    To check both requirements, open the python script console and do the following commands

     import Tkinter
     import unidecode
    

    If you don’t see any errors - done.
    Usage is simple - run the script and check the different options.

    What should work is

    • sort/delete duplicates on whole text (aka nothing is selected)
    • sort/delete duplicates on vertically selected text

    not supported yet:

    • sort/delete duplicates on rectangular selection

    Cheers
    Claudia

    Btw. I spent most of the time creating this ugly window - so if someone wants to create a nicer gui - please go for it. I’m not really good in designing UIs.



  • tkinter doesn’t work:

    Initialisation took 219ms

  • I found out something else, about that easylist file,
    textfx’s case insensitive sort results in 69234 entries,
    which is the same as ue’s result!
