[Qt-creator] SyntaxHighlighting + Bison/FLex

[David Schulz]

Hi Jeremy,

That sounds more like a semantic highlighter to me. Have a look at 
SemanticHighlighter::incrementalApplyExtraAdditionalFormats in 
src\plugins\texteditor\semantichighlighter.cpp and the usages in the 
QML/JS and C++ semantic highlighter.


Br,

David
