I also noticed that the plugins admin does not include Columns++. Maybe @Coises just missed the cutoff on the plugins list?

@donho Here is a possible regression - When I use the arrow keys to move the cursor Notepad++ is acting like it’s in column mode though the status line says I’m not. Maybe I’m activating multi-edit, whatever that is?

For repro I’m using v8.6 (64-bit) portable but I also saw the same thing in v8.6 x32 installed and v8.6 x32 portable.

1 1 1 1
2
3 3 3 3
4

abc xyz
abc xyz
abc xyz
abc xyz

I put the cursor after the first abc and then while holding Alt+Shift I did down arrow three time. So far it looks good with a 4x0 column according to the status line.
I then did an up-arrow. The status line says I’m out of column mode but the 4-line high “cursor” moved up. I did up-arrow a few more times and then started doing right arrow. The cursor remained at 4 lines but as I moved right the cursor fragments. I think I lost one as I see three flashing.

Esc exits the multi-cursor mode.

With v8.5.8 the first part works to create a 4x0 column. When I do the first up-arrow it exits column mode and has a single cursor, which is what I am used to.

@donho Here’s another column mode related regression that does not happen in v8.5.8

I was looking over some old notes at a series of JPEG file names and their sizes. I saw:

768NBSB×NBSB1024
768NBSB×NBSB1024
768NBSB×NBSB1024
768NBSB×NBSB1024

I did not need the NBSB and so did a column select of the first NBSB in all four lines and hit Del. The NBSP were replaced with xA0. It is a UTF-8 encoded text file meaning it’s encoded as \xC2\xA0 I did not test using Del with other multi-byte Unicode sequences.

Using backspace to column delete the NBSP is okay. Using Del in non-column mode to delete the NBSP is ok.

In the example image below I column-deleted the first NBSP on the first two lines.

It’s by forgetting. Sorry about that.
It will be in v8.6, or in v8.6.1, I’ll see.

It’s a regression, but a minor one.
Could you create an issue on GitHub and ping me please?
It’ll be fixed in the next version (v8.6.1).

I cannot reproduce the issue you report at all.
Is anyone here can reproduce it?

OK, I misunderstand it.
What’s the Hex value of NBSB? So I can try to reproduce it.

But this is NOT true with 8.5.8 and BetterMultiselection plugin installed and enabled. With that, the first up-arrow keeps the multiple carets; just moving them (what the “up” is telling it to do). It takes an Esc press to get back to one caret.

I’m not saying that the plugin is doing it totally correctly, but, it may be what users of the plugin have gotten used to as the “correct” behavior in that situation.

@donho said in Notepad++ v8.6 Release Candidate:

Yes, I can reproduce (though at first I couldn’t) – maybe like me, @donho did a 4x1 column selection instead of 4x0 column selection:

Step 1: column selection, showing it’s one character wide:

Step 2: hit Del/Delete key: it deletes the whole NBSP, without leaving

Confirm: View > Show Symbol is showing all characters, so it’s not just hiding something:

Original Conclusion: thought I could not reproduce. But as I was re-reading @mkupper’s post, I wondered if I misinterpreted.

Undo, so it’s back to the original

Then Step 1: do a 4x0 zero-width column selection

Step 2: Del/Delete =>

Confirmed the bug report. With a 0-width column selection, hitting Del before NBSP broke it into its constituent bytes and just deleted one byte rather than one character.

Tried with some accented characters (2 bytes each) and then some smilies (with 3-4 bytes each):

Before:

After hitting Del once:

So it’s not just NBSP. With a 0-width column selection, hitting Del when the next character is a multi-byte UTF-8 character causes it to delete only the first byte rather than the whole character.

@mkupper’s NBSB was just a typo for NBSP; see the right value in his screenshot

NBSP is the non-breaking space, at U+00A0 , which is UTF-8 encoded as the two bytes c2a0.

Please check the fix:

PeterJones

@donho ,

I first tried with the “Notepad++.MSVC.x64.Debug” artifact: I loaded my example file from yesterday, did the zero-width selection, and hit Delete, and that caused an MSVC assertion error:

… But as I was writing this reply, I realized that I probably don’t have everything set up right for DEBUG builds, so I thought I would try the RELEASE build:

When I run with the “Notepad++.MSVC.x64.Release” artifact, the zero-width column selection followed by Del works as expected on the multi-byte UTF-8 characters. So the fix looks good to me. But you should probably wait for @mkupper to confirm as well, because he might have a different sequence, which may or may not behave the same as my experiment.

There is no special setup for running a Debug build, so you are set up correctly. :-)

The problem is: Someone at some time wrote some poor assertions, and now they just get in the way of things. OR…the assertions were good at the time written, but now other things have changed, and no one maintained the assertions, so now they aren’t so good. :-(

update: the tabs and NBSP didn’t come through, so here it is base64-encoded using the MIME Tools plugin:

Hmm… using debug built locally binary, with 0 length column mode selection in front of all special chars then DEL - no assertion.

Could you provide the accurate instructions to reproduce the assertion please?

PeterJones

@donho ,

I found the problem on that. When I got the assertion error, I was still using a corrupted version of my testfile that had some of the NBSP as a single xA0 instead.

I can also reproduce the error by pasting in this base64 and decoding it:

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

So the error is unrelated to the column-delete, and instead related to the DEBUG-build’s handling of invalid UTF-8 sequences in certain unusual situations. (I don’t think it’s critical that a debug build has difficuly with invalid UTF-8. I verified that the v8.6-RC build and the RELEASE build on this PR don’t do anything unpleasant under the same circumstances. Unless you want to make the DEBUG build more robust against invalid UTF-8, I’d probably recommend not worrying about it.)

@PeterJones

Thank you for the detail explanation.
I will do a RC2 immediately.
