sort file removing duplicates possible?
-
Hello @patrickdrd, @scott-sumner and All,
Generally speaking, when you want to remove duplicate lines, from a
PREVIOUSLY SORTEDlist, just use this simple regex S/R, below :SEARCH
(?-s)(.*\R)\1+REPLACE
\1This regex is quite fast, because, in case of numerous duplicates, the part
\1+grabs all the duplicates ( with their EOL characters ), at once and just rewrites the first item of each block :-))IMPORTANT : the last item of your sorted list must be followed by EOL character(s) !
Cheers,

after trying both the macro and the textfx solution for a long time,
I’ve seen that still ultraedit’s sorting works much better than both of them,
I first rejected the macro for textfx’s favor but I found out lately that neither the latter does a good job, at least I prefer the sorting done by ultraedit ,sorry,
I don’t have an example at the moment, I’ll post again when I do -
sorry, did not read the whole thread but what about a python one liner?
editor.setText('\r\n'.join(list(set(editor.getText().splitlines()))))Cheers
Claudia -
forgot sorting
editor.setText('\r\n'.join(sorted(list(set(editor.getText().splitlines())))))Cheers
Claudia -
thanks, I’m keeping that too and I’ll let you know

ok, I tested, this doesn’t work either somehow, at least doesn’t work like ue’s one, i.e.
I tested with easylist from: https://easylist.to/easylist/easylist.txt (69883 lines),
ue’s function cuts it to: 69238npp results:
python scipt: 69818
macro (scott) is a bit slow and results in 19610 lines (!) and
textfx results in 69818 as wellguy038 regular expression results in 28109 lines,
according to my experience, I bet that ue’s result is the correct one,
at least to my taste -
could you, by any chance, upload the ue cutted list?
To see the differences.Cheers
Claudia -
yes, of course, please tell me where, pastebin doesn’t work, it’s blocked here (at work),
any other suggestions? -
actually pastebin is my first choice as well and haven’t used others for quite some time now.
Heard about
https://www.zippyshare.com/
https://www.sendspace.com/should be good and anonymous but haven’t tried it so far.
Cheers

Yea, I used to be a fan of regular expression replacement when doing this, but with “larger” datasets there always seems like there is so much tweaking and experimentation needed to get it right (for a particular dataset) that it is hardly worth it, unless you like playing with regular expressions all day instead of solving a particular problem and moving on quickly.
A Pythonscript solution such as @Claudia-Frank 's seems fine…
-
ok, but why results are inconsistent (with large datasets)?
@Claudia-Frank, unfortunately I’m not able to access zippyshare either,
so I’ll upload to pastebin from home if we don’t find another solution -
I installed the ue trial version but can’t find the menu item to delete the duplicates.
Is there anything I need to install in addition or am I blind and don’t see the obvious?Cheers
Claudia -
ok - found it - obviously blind :-D

Various reasons, sometimes a regular expression approach to this needs to be refined to match the data better before it works well. If you search up some other threads on this topic you can trace through the evolution of a regex approach on certain datasets. However, I suspect you just want to get a workable solution and move on…and I fully endorse that. I’m tired of trying to use regex for this kind of thing. :)
BTW, @Claudia-Frank going the extra mile…installing UE trial version just to track this down…nice!

… boots are made for walking … :-)
I’m confused about how UE does sort and delete duplicates.
Used default settings.Only sorting
Sorting and deleting duplicates
There is obviously something wrong about UEs algorithm, isn’t it?
And the version I used cut the list to 63732 lines.Cheers
Claudia -
so… another number? amazing!
I’ve got version 16 which is lite somehow
-
me too - that is actually the latest one available for ubuntu.
Cheers
Claudia -
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
69889linesNow, 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 textThen, I used the regex S/R, that I spoke in my previous post :
SEARCH :
(?-s)(^.+\R)\1+REPLACE :
\1I obtained a file of
69790lines => The difference of99lines ( theduplicateones ) 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?
