This feature is in SinkWorld where there can be multiple lexers each controlling a styling buffer with separate style valid ranges. On the output side, multi-layer drawing can combine the styling buffers into a composite image. http://scintilla.sourceforge.net/url.png URL lexer http://scintilla.sourceforge.net/urlrec.png Combined with ASP lexer I just fixed up the URL recognizer a bit for that picture as the current download wasn't allowing some characters in URLs. This current version doesn't change as you hover over the URL. > I wanted to have hyperlinks in every lexer but I didn't want > to extend each lexer. > ... > The hotspots should be lexer/language independent.

You should think about issues where other pieces of code want to work with the indicators and so may need to vary the indicator bit used. If this is for a private build then it is OK but many applications use indicators for showing information such as syntax warnings. Hooking this into the normal lexing means that you are dependent on the existing state for determining the range to style. You can lex the same range as the main lexer is being asked to lex although lexers may ignore the range given and lex more or less if they want to. If they lex more then your lexer may never be called for the extra piece. You could lex from the beginning of the asked range to the end of the range that was styled by the main lexer (GetEndStyled()). This is one of the reasons SinkWorld has separate valid ranges for each styling buffer, the other being that some stylers may run very slowly such as a compiler or URL verifier and so be performed in idle time. > What about a new indicator > INDIC_HOTSPOT or INDIC_HYPERLINK?

If the amount of code isn't too large then it could go in. You should start with a recent download from CVS or http://scintilla.sourceforge.net/scite.zip as there have been changes to indicator drawing recently.
