How to get breakpoint list ?

Ok, that part work, I get the scintilla for the current document, but for the next part I don’t find example, I tried that:

Here is some NppExec code to iterate the bookmarks in the active document.

SET LOCAL POS = 0
SET LOCAL FOUND = 0
SET LOCAL MASK ~ 1<<24

:LISTNEXT
SCI_SENDMSG SCI_MARKERNEXT $(POS) $(MASK)
IF $(MSG_RESULT)==-1 GOTO STOP

NPP_CONSOLE on
SET LOCAL FOUND = 1
SET LOCAL LINE ~ $(MSG_RESULT) + 1
SCI_SENDMSG SCI_GETLINE $(MSG_RESULT) @""
ECHO $(FULL_CURRENT_PATH):$(LINE):	$(MSG_LPARAM)

SET LOCAL POS = $(LINE)
GOTO LISTNEXT

:STOP
IF $(FOUND)==0 THEN
    MESSAGEBOX "No Bookmarks Found"
ENDIF

The API calls are pretty much the same (SCI_SENDMSG = ::SendMessage(getCurrScintilla(), <MESSAGE>, wParam, lParam)) and you can do C++ looping much cleaner than the GOTO required in NppExec.

I usually try to mock something up in NppExec (or “PerlScript” or PythonScript) before trying to add to a plugin.

In my notes on bookmark manipulation I have this thread and specifically THIS POST noted.
The logic flow there can probably help you.

you should have just said, "no it’s not too much complicated, you just have to get the current scintilla, like that [little code] and retrieve the bookmark for each line like that [little code].

I don’t know…
Nobody here is going to “spoon feed” you every little detail.
If you’re a plugin writer, a certain level of “sophistication” is assumed.
Pointing you to the documentation should be enough.
Of course, I did point you to the documentation, and a specific function in those docs, but then in your follow-on posting you seemed to ignore that and went with a different function…
I’m not sure what to think.
I wish you good luck with your endeavors.

I just need help for notepad++ plugin development in c++, you redirect me to scintilla api documentation, which has nothing to do with c++.

Sorry I followed your link and see that SCI_MARKERGET returns the bookmark at a specific line, perfect for a test. I tested and it doesn’t work. But even if you’re convinced I’m a bad programmer, you think I would have more chance with SCI_MARKERNEXT that seems more advanced.
If you tell me why I get “0”, I’ll can understand and make both work, but you doesn’t seem to know c++, then just tell me that.

@Michael-Vincent Thank you for the code, what I don’t understand is how to turn that in c++, the functino is ::SendMessage(getCurrScintilla(), <MESSAGE>, wParam, lParam)), then I need to put pos, mask and the result in wparam and lparam, 3 parameters into 2 ?

@Gregory-D said in How to get breakpoint list ?:

long line = 0;
int marker = 0;
::SendMessage(curScintilla, SCI_MARKERGET, line, (LPARAM)&marker);

This is :

long line = 0;
int marker=::SendMessage(curScintilla, SCI_MARKERGET, line, 0);

Right ?

I think maybe you’re not connecting the dots. The Scintilla docs @Alan-Kilborn linked are crucial since the Notepad++ editing component is based on Scintilla. As for “translating” my NppExec script to C++:

[...]

HWND getCurScintilla()
{
    int which = -1;
    ::SendMessage( nppData._nppHandle, NPPM_GETCURRENTSCINTILLA, 0,
                   ( LPARAM )&which );
    return ( which == 0 ) ? nppData._scintillaMainHandle :
           nppData._scintillaSecondHandle;
}

[...]
int line = 0;
int mask = 1<<24;
SendMessage(getCurScintilla(), SCI_MARKERNEXT, line, mask);

That should get you the first bookmark since N++ uses 24 as the bookmark marker and thus bitshitfted 24 is the mask the Scintilla call requires. You’ll need to put your own C++ code / logic around that to determine if you’ve found them all and how to find the next one, but again, my NppExec “pseudo” code should help you with that - as will the Scintilla docs.

Cheers.

sorry:

int markerAtLine = ::SendMessage(getCurScintilla(), SCI_MARKERNEXT, line, mask);

Cheers.

I’m sure about that, but what Alan Kilborn doesn’t understand is that my problem is not about Scintilla api that is documented but with the c++ conversion.
Then right code is:

				long line = 1;
				int mask = (1 << 24);
				int result=::SendMessage(curScintilla, SCI_MARKERNEXT, line, mask);

You helped me, thanks.

Then right code is:

Yup - methinks that’s correct.

Tangential to the topic, but not quite off-topic:

I started working with an older version of Visual Studio recently, due to what is used for certain projects at work.

I notice that its breakpointing symbol is VERY similar to Notepad’s bookmark image, the main difference being coloring:

In the past I’ve had a passing thought of “where did the design for the N++ bookmark come from?” as it isn’t a stock Scintilla indicator symbol like those shown HERE (with a little “scrolldown” from where that link goes).

Perhaps this “red” older-Visual-Studio BP symbol (shown above) was the origin of the N++ bookmark symbol.

The obvious stock Scintilla choice (had it been used) would have been:

BTW, current VS (2019) BP symboling is much less “fancy”; appears rather flat:

Do you have NppExec (or Python Script) that allows a script to run at startup?

SCI_SENDMSG SCI_MARKERDEFINE 24 SC_MARK_BOOKMARK
SCI_SENDMSG SCI_MARKERSETFORE 24 255
SCI_SENDMSG SCI_MARKERSETBACK 24 255

(Python Scrip implementation will vary ;-)

Cheers.

@Michael-Vincent

Yes, that is good information.
The Pythonscript implementation is very similar and straightforward.

BTW, I wasn’t complaining about Notepad++'s default bookmark symbol image in any way. Just wondering/commenting on its possible origins. It hadn’t occurred to me that the origins might be with an earlier VS version.

Didn’t think you were :-) it was more of an exercise to see if I could do it. I have an NppExec ‘marker’ script that adds different colored “bookmarks” by placing normal bookmarks and then converting them. So I though it’d be possible to just change the default symbol / color.

Cheers.
