How to use SCI_MARKERGET in scintilla?

[sapero]

I want to implement language independant auto-indentation. I can handle Enter key, to increment the indent, but have no idea how to unindent an "endif" like line.
I don't want to compare the text from editor with hardcoded keywords, or keyword-parts.

My editor has predefined markers for the folding. If there is an IF, a box-minus marker appears. On a line with endif, or '}' - there is an L marker (two lines).
My first idea was to detect a keystoke, and check if the marker changed to L, but SCI_MARKERGET always returns zero. So what do I need to do, to use this message?

This is just an idea could be absolutely stupid.

You have somewhere the words defined for the syntax highlight and there must be an interseption allready for do the highlight.

What would be if you would define the "endwords" - endif, endselect ....- with additional out of range ASCII chars like : endif + chr$(1) or maybe just an extra LF.
You could hack the syntax highlight callback to check for this extra char(s).

Ok I just recognized what you actually wrote.

...but SCI_MARKERGET always returns zero...

I found this sample may help:

int nCurLine = GetCurrentLineNumber();
// what is the current line number?
int nState = SendEditor(SCI_MARKERGET, nCurLine); // what are
the markers on this line
if ( nState & (1 << SCINTILLA_BOOKMARK)) // is the
bookmark there?
{
SendEditor(SCI_MARKERDELETE, nCurLine, SCINTILLA_BOOKMARK); // delete it!
m_nBookmarks--;
if (m_nBookmarks < 0)
m_nBookmarks = 0;
}
else
{
SendEditor(SCI_MARKERADD, nCurLine, SCINTILLA_BOOKMARK); // add it!
m_nBookmarks++;
}

It seems that SCI_MARKERGET does not include auto-folding markers. I just saw in scintilla sources, that all folding markers, before drawing, are computed from fold level in the current and next line - editor.cxx -> Editor::PaintSelMargin -> find "Decide which fold indicator should be displayed".

I don't know about thet but they are "special":

Code Select Expand


Marker numbers 25 to 31 are used by Scintilla in folding margins, and have symbolic names of the form SC_MARKNUM_*, for example SC_MARKNUM_FOLDEROPEN.
