"Summary" feature improvement

[guy038]

Hello, @alan-kilborn and All,

Alan, first of all, I could have told you that I didn’t want to bother modifying your script and that I’d integrated it, as is. But, the truth is that I’m still a long way from understanding your script and seing any possible simplifications :-((

---

So, here is my final version of this Python script which can be used instead of the View > Summary feature. It contains the @alan-kilborn section which reads the right part of the status-bar, relative to the current encoding

I have to split this script into two consecutive posts !

Hi, Alan and All,

( Continuation of the previous post )

Now, I’ve come accross a problem with the encodings !

Have you ever noticed that, when you decide to re-interpret the present encoding of a file with the View > Character Set > ... feature, that there are two possible scenarios ?

• A) - The present econding is an Unicode encoding with a BOM ( Byte Order Mark ). So, either the UTF-8-BOM, UCS-2 BE BOM or UCS-2 LE BOM encoding

• B) - The present encoding is an ANSI or UTF-8 file, so without a BOM

In the first case, whatever the new encoding chosen ( one-byte or two-bytes encoding ), the file contents do not change and my script just respects the real encoding of the current file

For example, with an UCS-2 LE BOM encoded file, if I change its encoding to View > Character Set > Western European > OEM-US, my new summary just consider that it’s still a true UCS-2 LE BOM encoded file, leading to a correct summary report !

In the second case, the new encoding chosen does modify the current file contents in the editor window. In addition, it automatically supposes that the current file is an UTF-8 encoded file, leading to erroneous results in the summary rapport :-( However, the current file contents, saved on the disk, seem still unchanged !!

For instance :

• Open a new tab

• Use the Encoding > Convert to UTF-8 feature, if necessary

• Enter the four chars Aé☀𝜜, without any line-break, at the end

• Save this file as Test-UTF8.txt

• Using my script, you get, in a new tab :

• Run the View > Character Set > Western European > OEM-US feature

And, at the same time, a prompt displays this warning :

CURRENT file re-interpreted as OEM-US => Possible ERRONEOUS results
So, CLOSE the file WITHOUT saving, RESTORE it (CTRL + SHIFT + T) and RESTART script

Indeed, this time, as the file contents are unchanged, the length on DISK is still correct but the BUFFER length is wrong, due to the re-interpretation of the characters by the OEM-US encoding. That’s why I preferred to add this warning at the end of the script !

Now, do as it is said :

• Close the Test-UTF8.txt file ( Ctrl + W )

• Restore it ( Ctrl + Shift + T )

• Again, you get the UTF-8 indication, for the Test-UTF8.txt file, at right of the status bar

• Re-run my script

=> This time, we get again a correct summary, without any prompt !

Alan or other python gurus, feel free to improve this last version and/or test on various files if all the numbers shown are coherent !

Hi All,

I"ve just realized that, up to now, I simply improved my script with an old version of N++ ( v7.9.2 ). I apologize…

So, I’m first going to update my last portable version, on my W10 laptop, from v8.5.4 to the v8.6.2 version and I will update my script and redo all the tests

See you later !

:-(

You ought to close out these ancient versions…permanently.

[guy038]

Hello, @alan-kilborn and All,

I’e just discovered that, since the v8.0 N++ version, the UCS-2 BE BOM and UCS-2 LE BOM encodings are able to handle all the characters over the BMP. Thus, these encoding were renamed, respectively, as UTF-16 BE BOM and UTF-16 LE BOM !

Note that, with these two encodings, each character with code > \x{FFFF} is built with the surrogate pair mechanism, so with two 16-bytes chars. Consequently, the total number of characters in the buffer = 2 (BOM) + number of chars <= x{FFFF} x 2 + number of chars > x{FFFF} x 4

For example, the simple string Aé☀𝜜, without any EOL, in an UTF-16 BE encoding file, is coded with 12 bytes as :

FE FF 00 41 00 E9 26 00 D8 35 DF 1C
----- ----- ----- ----- -----------
 BOM    A     é     ☀       𝜜

---

So, here is my final and updated version of the script, which works in all versions since the v8.0 one !

If you’re still working or doing tests wih a N++ version prior to v8.0 :

• First, change any sub-string UTF-16 with UCS-2, in the python script

• And, of course, do not forget to get rid of any character over \x{FFFF} in your UCS-2 BE/LE BOM encoded files, before using this script

---

Note, that the encoding problem, described two posts ago, when trying to encode any file, without a BOM, with a Encoding > Character Set > ... encoding, stll remains. Thus, the warning prompt is still present at the end of this final version !

---

Now, I’m going to update an old post where I explained the poor performance of the present summary feature. I’ll take the opportunity to include the instructions for understanding this improved script !

@guy038

You have this line in your script:

line_list.append (' ' * ((Line_title - 37) / 2) + 'SUMMARY on ' + str(datetime.datetime.now()))

I would suggest changing it to:

line_list.append (' ' * int((Line_title - 37) / 2) + 'SUMMARY on ' + str(datetime.datetime.now()))

This is because, without the int, under Python3 we see the following error:

TypeError: can't multiply sequence by non-int of type 'float'

Hi, @alan-kilborn and All,

Just follow this link to find out why I decided to improve the View > Summary feature and to get the last version of the Python script, wich gives us a decent and exact Summary feature !

I’m MIGHTY confused as to why you felt the need to reanimate a several-years-old topic/thread to continue discussing what you dedicated this current thread to…
Why not just keep talking here?

[guy038]

Hello, @alan-kilborn,

Sorry to get you confused. I’ll try to explain why I wanted to continue on the other thread !

• Firsly, I wanted to show from where and why my script came : the whole logic of the View > Summary needed to be completely rebuilt :-((

• Secondly, I wanted to update these old posts. Indeed, at that time, the v7.9.1 N++ version was just released. So, I recently did some tests to verify if, consecutively to the encoding improvements of the v8.0 version, the global logic of the summary has been improved. Unfortunately, the View > Summary feature still gives wrong results, especially when the present file is a UTF-16 BE BOM or UTF-16 LE BOM encoded file :-((

• Thus, it seemed obvious to me to continue on this thread and add the consecutive versions of my script !

---

Now, I realized that I could have stayed with this new thread, and put a link to my initial post to help people to understand the reasons of this Python script !

So, unless you’re terribly upset of my decision ( which would need a lot of modifications ) , I suppose that I’m going on to post the possible new versions of my script on the other thread !

In order to get it more clear, I could simply rename this present thread as Summary feature improvement and rename the other thread as Emulation of the "Summary" feature with Python script

Alan, what do you think of ?

Best Regards,

guy038

[Alan Kilborn]

@guy038 said in Improved version of the "Summary" feature, ...:

what do you think of ?

I wouldn’t bother trying to rename things at this point.
It’s no problem simply because I was confused (that’s MY problem). :-)
Carry on… :-)
