[Pharo-dev] AST based syntax colouring: Shout cleanup possible

Hi, Interestingly with both Rubric and TxTxt we now use AST based syntax coverage by default (and the setting has no effect, it was just for PluggableTextMorph). As it seems that after the fixes that where done (mostly by Nicolai, thanks!!), the AST based syntax colouring is good enough to replace the one using SHParserST80. I am sure there are some smaller glitches still to be fixed, but it seems it has proven itself to the point we can start to clean up. SHParserST80 is used in addition by code completion, so we can not yet remove it yet, but we can radically simplify the SHTextStyler hierarchy. Anyone wants to give it a try? Marcus
