Description Sven Brauch 2013-09-19 13:37:23 UTC 
Currently all variables in the top-level are boring green. That's fine for larger files but if you just type a short script, you'd rather have them highlighted. A nice way to solve this would be to always use rainbow colors if there are no functions defined in the file, and the default otherwise.
To achieve this, you'd want to look at pythonhighlighting.cpp:useRainbowColor, and return true from that function if the declaration's context() is
 a) the same as declaration's topContext(), so the declaration is a top-level declaration, and
 b) all declarations in the declaration's topContext() (use searchInParents=false for the allDeclarations() method call) have "isFunctionDeclaration()" set as false.
Otherwise, just return the default.

Since this function will be called quite often, the result of b) should be cached in a class member.

Reproducible: Always
Comment 1 Sven Brauch 2013-09-19 13:38:21 UTC 
Correction: instead of looking at isFunctionDeclaration(), it'd be better to look if the declarations' internalContext() is 0 or not, since that'll also catch class declarations.

Rainbow color-highlighting for top-level variables

Enable rainbow-color highlighting for top-level variables if there are
no class or function declarations.
Currently it's also disabled if there are imports, although more by
accident than intentionally.
