@Petr-Jaja ,

Here’s a series of screenshots for the 6 steps, showing it in action

Hello, @petr-jaja, @peterjones, @astrosofista, @alan-kilborn and All,

I think that a solution, in fewer steps, should be possible !

Let’s start with the initial example of @petr-jaja, in this post :

https://community.notepad-plus-plus.org/post/63869

First, like @peterjones said, we copy the MD5 checksums at beginning of each line :

SEARCH (?-s)^.+\t([[:xdigit:]]{32})\t
REPLACE \1\t$0

So, we get this text :

Now, three options are possible :

You would like to get an idea of the different duplicate MD5 strings and lines which need future deletion ( option A )
You would like to delete the duplicate MD5 strings, one at a time, with the Replace button ( Option B )
You are rather confident about all the replacements to achieve . For instance, you have made a backup of your file ! ( Option C )

Whatever the option chosen, remember to :

Tick the Wrap around option
Select the Regular expression search mode

Option A :
- Open the Mark dialog ( Ctrl + M )
  - SEARCH (?-s)^.*([[:xdigit:]]{32}).*\R(?:.*\1.*\R)+
  - Tick the Bookmark line option
  - Click on the Mark All button
  - Note that using the Search > Bookmark > Remove Bookmarked Lines option, you can also delete all the lines with duplicate MD5 strings !
Option B :
- Open the Replace dialog ( Ctrl + H )
  - SEARCH (?-s)^.*([[:xdigit:]]{32}).*\R(?:.*\1.*\R)+
  - REPLACE Leave EMPTY
  - Click several times on the Replace button to delete the first duplicate blocks of lines
  - If everything seems OK, you may click once on the Replace All button
- After deletion of the lines with duplicates, with the options A or B, uses the following regex S/R to get rid of the temporary MD5 strings at beginning of lines ;:
  - SEARCH (?-i)^(?!Product).+?\t(.)
  - REPLACE \1
Option C :
- Open the Replace dialog ( Ctrl + H )
  - SEARCH (?-is)^.*([[:xdigit:]]{32}).*\R(?:.*\1.*\R)+|^(?!Product).+?\t(.)
  - REPLACE ?2\2
  - Click, just once, on the Replace All button

Whatever the option A, B, or C used, we obtain that text :

@peterjones,

It’s weird : Although there is a tabulation char after each word metalo, the lines are correctly sorted by increasing time if I perform a zero-length selection at column 9, right before the year !
It’s a chance, for me and you, that the Date-Time column is located near the beginning of lines. It allows us to find the initial lines order back, with a classical selection ;-))

astrosofista

@guy038 said in Identical strings in column:

Well, it’s going worse than I initially thought ! And the @alan-kilborn’s assumptions are certainly true, as well !

Intrigued by test reports with mixed outcomes, I run further tests on the same example data aiming to obtain some clarification. As before, tests were run on Windows 7 and NPP v7.9.1 and 7.9.4 RC, and threw the same outcome.

Example data with tabs, zero-length column mode selection in:

column 01 -> sorted correctly, the column mode selection remains unchanged
column 13 -> sorted correctly, but lost the column mode selection and the caret was moved to line 1, column 1
column 17 -> sorted incorrectly, lost the column mode selection and the caret was moved to line 1, column 1

Now if I select all the tabs between strings 013300000001 and any checksum with a rectangular selection, backspace to delete them, get a zero-length column, type four spaces and immediately run a sort, then the command is ignored and example data remains unchanged.

Need to make a new zero-length column mode selection at columns 01, 13, or 17 in order to get example data correctly sorted. On the downside, lost the column mode selection and the caret was unexpectedly moved to line 1, column 1.

Hope this makes sense.

Hi, @petr-jaja, @peterjones, @astrosofista, @alan-kilborn and All,

@astrosofista, thanks for your insight, but I worked on my side and I’ve found out a coherent explanation which means that is, finally, a predictable bug !

Yes, I’m glad because I find out the algorithm which fully explains how the column-mode sort behaves ;-))

First, it only concerns the TAB characters, located before the position of your zero-length column-mode selection. Now :
For each TAB character, estimate the number n of positions, taken by the TAB character and, then, note the number n - 1
Add up all these numbers n- 1 ( so, n1 - 1 + n2 - 1 + n3 - 1 + … = S )

This sum S is the offset between the user column Cu of your zero-length selection AND the real column Cr, used to perform the column-mode sort. Hence the relation Cr = Cu + S

One example ( refer to the picture, below )

The first table, before the sort, with a zero-length column-mode selection, at column 45
The second table, after the sort, is not sorted, obviously, at column 45
Each line contains 8 tabulations before column 45
The positions, taken by each tabulation, are, respectively, 4, 2, 3, 1 3 2, 3 and 4
So, the numbers n - 1 are, respectively, 3, 1, 2, 0 2 1, 2 and 3
The sum of all these “n - 1” numbers is 14
So, although you think to sort at column 45, where you did the column-mode selection, the effective sort will begin at column
45 + 14, so at column 59 of each line ! ( The column-selected column, in the picture )

Best Regards

guy038

P.S. :

I also verified that, after changing the number of positions for tabulations, in normal text, either below or above the default value 4, in the Preferences dialog, my algorithm is still correct and always gives, in all cases, the real column of the sort !
Text in an ANSI encoded file, is sorted, using this same algorithm, too

Last thought :

If you intend to use a column-mode selection for a sort, starting at a specific column, the best would be to run, first, a Edit > Blank Operations > TAB to Space command in order to delete any tabulation character, without changing the presentation of the text !

Alan Kilborn

So something smells bad here, and it isn’t just tab characters.

I looked at @guy038 's data, from the post where he said:

If I paste this data into a new tab, and convert tabs-to-spaces (to forget about tabs for now), I get something that appears like this:

If I then try to make a zero-width column selection, it looks like this:

But this isn’t right…the column caret should be to the left of the leading zero of the third column of data for the entire block, but it isn’t.

Thus if I attempt a sort, I definitely don’t obtain what I intend.
And no tabs involved.
This problem goes deeper than sorting, I think this is a Scintilla problem.
Just because the “little birdie” appears to take up two columns, he doesn’t–he’s only one character, just like all the rest of the final characters in column 1 of the data.

The following is what a proper column selection should look like for this data:

Hello,
Great :-) It looks very nice. I have tested three files and the algorithm worked fine. I have found there only one problem. If there are more than two equal strings in the file, the sequence 3 indicates only first two of them.
Tested on v.7.9.3 - 32bit

Thanks for this idea.
I have used at first TextFX Tools – sort lines by column and then marking lines according to your solution. Option A looks most suitable for my issue.

So,if your going to use the colum-mode feature, I think that the best is to switch, first, to a classical true monospaced font, like Consolas or Courier New !

Best Regards

guy038

Alan Kilborn

@guy038 said in Identical strings in column:

if … use the column-mode feature, … best is to switch … to … true monospaced font, like … Courier New !

So I’m confused.
My screenshots in my immediately previous post WERE made with the font set to Courier New.

So remembering that I’ve converted all tabs to spaces, if I put my caret here:

and I press Shift+Alt+downArrow, I should get this:

because that is the only way to keep the same number of characters to the left of both carets in their respective lines.

But what I actually obtain is this:

which puts 52 characters to the left of the caret on line 1, and 53 characters to the left of the caret on line 2. And for a column mode selection this makes no sense. It is like it is doing it on a visual basis…and what good is that?!

So as an example that should really hammer this home, what if I insert a character, for example, an a. Here’s what happens:

That’s wrong!

guy038

Hi, @alan-kilborn,

Don’t be bothered by my reply. Results can be different because of:

My old Win XP machine
Old versions of some of my fonts
The substitution fonts, used by the system, to display particular Unicode blocks
The fallback font used by the system

So, just be patient, for a while, and we’ll speak about this later, when I finally get this bloody Win 10 laptop ;-)) Otherwise, I’ll won’t be able to follow the latest N++ releases, any more !

@guy038

Hmmm, well, Courier New seems to be about as “vanilla” as one can get, given that it is the default font in Notepad++, and every Windows computer since time began has it (I suppose).

It seems like a non-power user trying to do what I’ve shown, is going to encounter a similar problem, and complain. I guess it is debatable whether or not a non-power user is going to be doing column blocking, but maybe not out of the question.

I’m willing to keep talking about this (if there’s more to say), in the context of your old computer, because I feel this has been in existence in N++ for a long time, so such discussions should be valid.

PeterJones

@Petr-Jaja ,

Sorry. I thought briefly about that condition when I started, but I didn’t notice your 3+ example in your data when I was debugging my answer, so forgot.i am on my phone now. Maybe later today, I will get a chance to be on the computer and work on this more.

Also, maybe @guy038 solution would work better for you. ( I haven’t tried it. )

PeterJones

@Petr-Jaja said in Identical strings in column:

If there are more than two equal strings in the file, the sequence 3 indicates only first two of them.

Okay, I found a workaround. I tried a clever alternation with \K on one of them, or anchoring on \G, but that wasn’t working easily. So, as I often do for practical solutions rather than optimized solutions, I added another step.

Step 4 (as listed above) will catch 2, or 4, or 6, or any even number of replicated rows. But any odd number of rows will miss the last row. So added a step 4b:

Find What = (?-s)^([[:alnum:]]{32}).✗\x20{3}.*\R\K\1\x20{5}
Replace With = $1\x20✗\x20\x20\x20

This will take care of the odd rows out. (I tried on 2,3,4,5,6, and 7 repeats, and I see no reason it woudn’t work beyond that)

Someone cleverer than I am might be able to come up with the magical formula to reduce the number of steps. And that’s great if you’re writing an application that will be running the regex millions of times, where the efficiency improvement might save significant time (and thus money) over the lifetime of the regex. But for a sequence that you’re just running once, or only occasionally on a small number of rows, efficiency isn’t the most important.

PeterJones

@Petr-Jaja ,

I also tried @guy038 solution from his “I think that a solution, in fewer steps, should be possible !” post: it worked first try, without modification, on your example data, or on data modified to have two, three, four, five, six, and seven repeat rows (and thus there is no reason it shouldn’t on reasonable n>7). So his should work for you, too.

Petr Jaja

@PeterJones , @guy038

I have tested your solutions and both work fine. However, for futher work I will use probably the solution from @guy038 because it is a little bit faster.
Thank you very very much for your help.
