bug? find_in_selection

Luuk v

When updating to 7.8.2, I did notice the line “8. Enhance “In Selection” option in Find dialog.” in the change.log

When selecting the first 13 lines of the change.log, and than a find for “er”, with option ‘in-selection’ checked. It finds a piece of text ‘outside’ the selection.

P.S. Why can an animated GIF not be uploaded here?

What you are describing isn’t what that change.log entry is referring to. Sadly, there is still no way to Find something in selected text only.

BTW, if you’ll notice, in the Find tab of the Find window, the In Selection checkbox appears wrapped in a groupbox along with the Count button. This implies (strongly) that ticking the In Selection checkbox will ONLY matter when the Count button is pressed, NOT when, say, the Find Next button is pressed.

Hello, @luuk-v, @alan-kilborn and All,

Alan is right about it. The point 8 enhancement, from @Scott-Sumner, prevents people for enabling the In selection option in case of multiple selections. In other words, you can tick the In selection option ONLY IF the main selection is active and not when column selection or multiple selections are active. Refer to :

https://github.com/notepad-plus-plus/notepad-plus-plus/issues/7532

Two work-arounds are possible :

The trivial one : copy your selection in a new tab and do a classical search !
Insert two different lines, standing for the beginning and the end of your selection and use an appropriate regular expression to limit the search between these two boundaries

The generic regex search to use is :

SEARCH (?s)Expression(?=((?!Start Line).)*End line)

So, assuming, for instance, the change.log file of Notepad++ v7.8.2 and :

The simple line of five 0’s ( 00000 ) as the starting boundary, inserted between points 3 and 4
The simple line of five 1’s ( 11111 ) as the ending boundary, inserted after last point 11

giving the text :

Notepad++ v7.8.2 enhancements and bug-fixes:

1.  Add key shortcuts in Save or not dialog.
2.  Add find in files filter excluding ability.
3.  Add "Open UDL folder" command.
00000er
4.  Fix issue of showing save dialog twice while cloned file is dirty.
5.  Enhance "Open Explorer" command in Folder as workspace with expected path.
6.  Fix tab dragging issues.
7.  Enhance "Close all but This" and "Close all to the left/right" commands while files are dirty.
8.  Enhance "In Selection" option in Find dialog.
9.  Fix Notepad++ blocked in notification zone issue.
10. Make end-of-line conversion operations macroable.
11. Fix "View Current File In" commands disabled problem in some situations.er
er11111

Included plugins:

1.  NppExport v0.2.9
2.  Converter 4.2.1
3.  Mime Tool 2.5


Updater (Installer only):

* WinGup (for Notepad++) v5.1.1

Open the Find dialog ( Ctrl + F )
According to your search and the change.log text, use the regex (?s)er(?=((?!00000).)*11111)
Tick the Wrap around option
Select the Regular expression search mode
Click on the Find button OR hit the ESC key to close the Find dialog and go on searching, hitting the F3 key

Remarks :

It’s worth to point out that the Start and End boundaries must be different and must not exist in current text !
Of course, you may use any character, instead of digits : !!! ..... %%% , #### ..... ----, START ...... END , …
You may use several zones Start Line ......... End Line, in your text. So, only the occurrences of Expression, within the different zones created, will be found ;-))
If you hit the Shift+ F3 shortcut, it always selects the last occurence of the previous zone scanned

A variant of this method would be to scan for the occurrences of Expression, from current location of caret till an Ending boundary. In that case, the generic regex can be shortened to :

SEARCH (?s)Expression(?=.*End Line)

Giving, in your example, the regex (?s)er(?=.*11111)

Of course, this alternate regular expression syntax only makes sense if there is only one ending boudary 11111

Alan is right about it. The point 8 enhancement,

It is good to be right. But…I suppose I should have supplied the information that @guy038 did to fill in the blanks about “point 8” in the change log.

It appears that 3 or perhaps more enhancements were made in Notepad++ 7.8.2 regarding the “in selection” checkbox. Here’s what I’ve found out after some investigation:

In selection won’t appear enabled if more than one selection is active, including a column mode selection (which is really several individual selections on different lines) – this is what @guy038 already discussed, and comes from this commit into the source code, which leads back to this issue.
Clearing of “marks” will now clear marks inside a selection, and bookmarks on lines touched by a selection, when In selection is ticked (otherwise it will affect the entire document). It comes from this commit into the source code, which leads back to this issue.
Purging of existing “marks” (via the Purge for each search checkbox) will only clear marks inside a selection, and bookmarks on lines touched by a selection, when In selection is ticked (otherwise it will affect the entire document), before the running of a new Mark All operation. It comes from this commit into the source code, which leads back to this issue.

That’s all I could find about In Selection changes on this Christmas night. Peace.

Hi, @alan-kilborn, @Scott-sumner and All,

Alan, I also investigated regarding the new features, of the Find dialog and its others tabs, recently added. Hence, the table, below, which recapitulates 9 enhancements, mostly created by @scott-sumner, as N++ contributor ;-))

Note that you’ve already reported about the first 3 issues !

May be, as a consequence of all these changes, since the N++ v7.8, I also noticed an other enhancement ( Edit : see above, issue 6042 ) :

If you previously did a Mark action, with the Bookmark line option ticked, then a click on the Clear All Marks button :

Erases the red highlighting AND the blue bookmarks, all together, if the Bookmark line option is still ticked
Erases the red highlighting AND keeps the blue bookmarks, if the Bookmark line option is presently unticked

I, personally, like this new behavior, as sometimes, after a Mark action, I prefer to get rid of all that red highlighting but I want to preserve all the bookmarks to move around with the F2 and Shift + F2 shortcuts !

I did some more research and it appears that one is this, also released in 7.8.0:
https://github.com/notepad-plus-plus/notepad-plus-plus/issues/3546

So maybe you wanna modify your table? :^)

Hi, @alan-kilborn,

Ah, yes I simply did a GitHub search with the criteria author:sasumner ! So, you’re right and I even found out the 6042 related issue !

Thus, I’ve just updated my previous post

Cheers,
