How to get Vertical Edge Settings programmatically?

[Derek Brown]

You used to be able to use SCI_GETEDGECOLUMN, but in v7.8.6 NP++ changed to using multiline mode for the vertical edge, and this message does not work with multiline mode.

Is there a way to programmatically get the vertical edge now?

There doesn’t appear to be; here’s the extent of the Scintilla functions regarding the vertical edge:

SCI_SETEDGEMODE(int edgeMode)
SCI_GETEDGEMODE → int
SCI_SETEDGECOLUMN(position column)
SCI_GETEDGECOLUMN → position
SCI_SETEDGECOLOUR(colour edgeColour)
SCI_GETEDGECOLOUR → colour
SCI_MULTIEDGEADDLINE(position column, colour edgeColour)
SCI_MULTIEDGECLEARALL

I got this from HERE .

Note that you can “add” and “clear all” for multi-edge mode, but there is no corresponding “get”.

[Derek Brown]

Yeah there’s definitely no way in the Scintilla messages. I was wondering if there was another solution that was supported, it would have to be something implemented in NP++ specifically. As a possibility, are the NP++ settings exposed to plugins in a useful way?

I’m not sure about that but someone else will know.
Even if they are exposed, I would think that this new multiple vertical edge stuff is too new to be supported yet in that way.

May I ask what you’re really wanting to do?
I use the single vertical edge in my setup, but I have Notepad++'s management of it completely turned off. I’m doing what I do via Pythonscript.
I would think you could do something similar, but without knowing anything further I can’t say for sure.

My CommentWrap plugin reads the vertical edge setting by default to decide at what column to wrap comments. This column can also be manually set, so it’s not a huge problem that it’s broken right now, but I would like to restore the functionality.

@Derek-Brown

Ah, okay then.
What I do won’t help that situation.

It does seem like a Scintilla oversight to allow setting of multiple edges without having a readback mechanism. Perhaps you want to have a look at the Scintilla issues list, maybe open an issue if there isn’t one.

But, sadly, I suppose I am the one that broke your plugin.
I’m sorry.
:-(

Yes, there doesn’t seem to be a call which is able to get every column
position set but the call itself seems to report the position from the first column.

Maybe @donho might consider implementing a new message
NPPM_GETEDGECOLUMNS and returning an array of ints?

[Derek Brown]

How is that call implemented? When I call in C++:

SendMessage(scintillaHwnd, SCI_GETEDGECOLUMN, 0, 0)

With edges set at 80 and 120 I get back 0.

[Ekopalypse]

hmm, strange - basically doing the same as you do

sci.call = <SciFnDirect>SendMessageW(hwnd, SCI_GETDIRECTFUNCTION, 0, 0)

    cpdef ssize_t getEdgeColumn(self):
        ''' Retrieve the column number which text should be kept within. '''
        return <ssize_t>self.call(<sptr_t>self.sci_pointer, SCI_GETEDGECOLUMN, 0, 0)

EDIT: except that I’m using the direct function

[Ekopalypse]

@Derek-Brown

just tried it with SendMessage and I do get back 80

[Ekopalypse]

@Derek-Brown
WAIT - there seems to be something wrong with MY code.
Because I set a different value (87) and I still do get back 80.

[Ekopalypse]

No, nothing wrong with my code but I guess there is another level of potential confusion.
It reports back what is configured in Number of columns

@Derek-Brown @Alan-Kilborn

ok - sorry for the noise. I didn’t use the latest 7.8.6 iteration.
I was still running a RC version. In the final version it does what @Derek-Brown said.
