[Qt-interest] Generic highlighter

[NoRulez]

Hi,

 

ok, I tried to extract the required files, but no luck. Could anybody help
me to use the “generic highlighter” with a simple QPlainTextEdit?

 

Much thanks in advance

 

Best Regards

NoRulez

I do not know of any stand-alone implementation of this. Having said that,

implementation in the qt-creator source does not appear to be particularly

The generic syntax highlighter stuff is all in one dir, namely: 


qt-creator/src/plugins/texteditor/generichighlighter


Not exactly true. The highlighter is interlaced with many other internal
components. It's not implssible to take this out, but ti's a great del of
work, and not trivial. I started doing this a few months ago, but decided to
stop as I noticed that Leonardo is still hacking inside Nokia on the
official version. Making a fork is smart only after the official version is
stable.


Hi all.

In general, the generic highlighter implementation tries to be as decoupled
as possible from Creator internals. But naturally, as you noted, there are
still parts relatively tied. However, if you are only interested on the
highlighting formats and don't care about code folding, for example, it
should not be that hard to strip it out.

The best example would be the generic highlighter auto-tests
(tests/auto/generichighlighter), which currently are not dependent on
Creator at all. Basically, it contains three fake header files
(tabsettings.h, basetextdocumentlayout.h, and syntaxhighlighter.h) which are
meant to replace the originals from Creator's text editor. A setup similar
to this should be enough for basic highlighting.

Diego, there is indeed a Leonardo in Qt, but as far as I know he is involved
with QML components. Perhaps, you confused the name?

Regards,
Leandro.
