Replace 1 + lines?

Claudia Frank

From my basic tests it looks like it should do the trick.
Tested utf-8, ansi, winows-1250, winows-1251 and winows-1252.
It works only with normal selection - not with column mode selection.

Hello, @claudia-frank,

What to say else ? Just wonderful and awesome, indeed !!!

I already tested the case of rectangular selection(s) and the upper limit of 2046 characters => No problem, it acts as expected :-)

Now, as always, when building a program, there’s a small bug with the lower limit of 0 character !

I, successively, tried to make an empty search selection, then an empty replace selection and, finally, both search and replace selections empty.

Note : To obtain, physically, a zero-length selection, I just select one character with the mouse, then move back the mouse, with a possible hit on the CTRL key, to only get the caret

Results :

If both selections are empty, the message Error: Either empty selection or unsupported selection mode detected occurs, as expected. Nice !
If, ONLY, the search selection is empty, the Find/Replace opens normally. May be, in that case, Claudia, a message would be better !
If, ONLY, the replace selection is empty, the Find/Replace opens normally, with the Find what: box filled and the Replace with: empty. That the expected behaviour, in order to delete all the search blocks of text found

I also noticed that if I Ctrl + click and select some text, ONLY, it is, logically, inserted in the Replace with box, leaving the Find what: box empty :-D

But, if I, simply, click, without the Ctrl key, and select some text, the message Warning: Only two selections are possible. Received:1 occurs. However, Claudia, I think it’s a valid case.

So, in the case of a normal selection 0, only, the Find/Replace dialog should pop up and contain :

A Find what: box, filled with the selection contents
A Replace with: box, wiped out of any [previous] character

Best Regards,

guy038

P.S. :

I found out something weird, but logic : If I build a one-line rectangular selection, this selection is correctly written in the Find what: box !!

@guy038

Guy, here the updated one.
A “one-selection” action results in opening the standard replace dialog behavior.
A “two-selections” action, even with an empty one, results in modifying the fields.
I see it as a benefit that you are able to decide that only one of the fields should be filled
and the other should be empty in any case.

Hello, @claudia-frank, @Scott-sumner, @pouemes44, @go2to, @jorge-campos, @herofiles, @azjio-azjio, @alan-kilborn and All

Thanks to @claudia-frank, this present topic and the discussions, below, about multi-lines search AND multi-lines Replacement :

https://notepad-plus-plus.org/community/topic/13823/replace-function/1

https://notepad-plus-plus.org/community/topic/13684/feature-request-textarea-search-replace/1

have, now, an ELEGANT solution, with her Python’s script, just above !

You just need to be able to do multiple selections ( Option Settings > Preferences… > Editing > Multi-Editing Settings > Enable CHECKED )

BTW, the upper limit of 2046 characters, in the Find what: box of the Find/Replace dialog, only, could be by-passed, easily :-). Indeed, just use the Regular expression search mode and use the generic regex (?s)Left-boundary.+?Right-boundary !

For instance, you can choose a particular character, which does not exist,yet, in your file(s) to be modified, and build the regex :

(?s)(#####\R).+?\1

This regex contains any non-null amount of characters between TWO same complete lines #####, with their line-breaks

So :

Do a normal selection of this regex (?s)(#####\R).+?\1, using the mouse
Then, with a Ctrl + Left Click action, simply, select your Replace block, multi-lines or not
Run the Claudia’s script above

=> Immediately, the Find/Replace dialog pops-up and :

The Find what: box is filled with the regex (?s)(#####\R).+?\1
The Replace with: box is filled with the block of text, which must replace the searched text

Best Regards,

guy038

P.S. :

@claudia-frank, I understand your point of view. Your script is quite flexible :-D. For instance, I was able to :

First, do a Ctrl + Clic selection of a multi-lines block of text
Run your script => Find what: box empty and Replace with: box filled with that multi-lines block
Select an second file, containing the text (?s)(#####\R).+?\1
Do a normal selection of that regex
Run again, your script => The find.Replace dialog, presently in the background, is, then, updated with this regex, filled in the Find what: box
Select a third file, containing the ##### boundaries lines
Perform the S/R on the contents of this third file

Et voilà !!

Many thanks, again, for this very, very, valuable script, indeed !!!

Hum… Already 3 h 25 !! I’d better go to bed : working tomorrow !

It would be nice if the author would make an additional window when the button is clicked
[http://radikal.ru/big/m0wcdchejv3ve](link url)

AZJIO AZJIO

The external program is working. I make a plugin and no longer works (EnumChildWindows).

Eko palypse

Sorry, but what are you try to tell us?
Which external program and which meaning has EnumChildWindows API in this context?

AZJIO AZJIO

I wrote a program for the test of regular expressions. It serves as a database. When you click a button, it fills in the search and replace fields.
I decided to make a plugin that will do the same. But the same program (exe and dll) work differently. EXE fills the fields, but the DLL can not fill.
I tried using EnumChildWindows to find the elements of the window, as is done in the examples above. But as a result, he found only 3 elements.
0 hwnd = 725602 Class = Button Title = Caption
1 hwnd = 2233572 Class = Static Title =
2 hwnd = 1707882 Class = SysTabControl32 Title = Tab1

Eko palypse

@AZJIO-AZJIO

without seeing/understanding the actual code it is hard to say what might be the issue
but, personally, I would not recommend using EnumChildWindows when trying to find a
dialog control window handle, instead use GetDlgItem.

AZJIO AZJIO

; PureBasic
hwnd = FindWindowEx_(NppData_nppHandle, 0, “#32770”, 0) ; hwnd = yes
If Not IsWindowVisible_(hwnd)
SendMessage_(NppData_nppHandle, #NPPM_MENUCOMMAND, 0, #IDM_SEARCH_REPLACE) ; Показать диалог поиска используя команду меню
EndIf
hwndEdit_1 = GetDlgItem_(hwnd, 1601) ; hwndEdit_1 = 0
hwndEdit_2 = GetDlgItem_(hwnd, 1602) ; hwndEdit_2 = 0
SendMessage_(hwndEdit_1,#WM_SETTEXT,0,GetGadgetItemText(#Combo_2 , n-1, 0))
SendMessage_(hwndEdit_2,#WM_SETTEXT,0,GetGadgetItemText(#Combo_2 , n-1, 1))

#32770

be careful about searching for the ordinal only, as every dialog uses it.
https://docs.microsoft.com/en-us/windows/desktop/winmsg/about-window-classes
Most plugins and internal npp windows are dialogs.

AZJIO AZJIO

I know it. I do not set the window class. I have no way to change this. The external program, as I said, works.

@AZJIO-AZJIO

Sorry, didn’t recognize the update.
Windows, sometimes, treats retrieving external and internal information differently.
Means, something you retrieved from an exe might differ from something
you want to retrieve within its own process.

In python, I would it do like this

import ctypes
user32 = ctypes.WinDLL('user32')
hwnd = user32.FindWindowExW(None, None, u'#32770', u'Replace')
hwndEdit_1 = user32.GetDlgItem(hwnd, 1601)
hwndEdit_2 = user32.GetDlgItem(hwnd, 1602)

This takes care that only the dialog with name Replace is found.

AZJIO AZJIO

I have done just that. Keyword only “Extended”. But using AutoIt3

$hWnd = WinGetHandle(“[CLASS:Notepad++]”)
If Not @error Then
If BitAND(WinGetState($hWnd), 16) Then WinActivate($hWnd)
_SendMessage($hWnd, $NPPM_MENUCOMMAND, 0, $IDM_SEARCH_REPLACE)
$hWnd = WinWait(“[CLASS:#32770]”, “Extended”, 2)
If $hWnd Then
ControlSetText($hWnd, “Extended”, “Edit1”, _GUICtrlRichEdit_GetText($hRichEdit_SPE))
ControlSetText($hWnd, “Extended”, “Edit2”, GUICtrlRead($PtnRep))
ControlCommand($hWnd, “Extended”, “Button18”, ‘Check’) ; 18 - regular expression (16 - normal)
EndIf
EndIf

on PureBasic code is the same for exe and dll. Search window “#32770” starts at the top, so it does not cause a problem. There are either no such windows or they are below.

Eko palypse

Maybe I have a wrong assumption what you are actually doing.
When you talk about an exe I assume that this is a different standalone program, correct?
When you talked about dll I assumed that this might be a npp plugin.
Now I get the feeling this is incorrect. Would you mind to explain what exactly is what
and what your ultimate goal is?

AZJIO AZJIO

Thank! The previous code helped. I saw in it the absence of a handle in FindWindowExW(None
I am intensively writing 2 plugins

AZJIO AZJIO

As a result, several plugins, but there is much to strive for.
