[petsc-dev] Style Guide: How to format single-line if/for/while-blocks?

[Karl Rupp]

Hi Barry,


>>> Well I think it is insane in 2012 that we all need to stare at the exact same ASCII strings with the exact same placement (each of you thinks is wrong) when we develop shared code, so please teach me how. Can this be done through some bridge that uses the current hg PETSc repository?

Will do.


>>>     Unfortunately the CPP crap in PETSc messes things up a bit, curse that CPP wish we could eliminate it all. And yes CPP is C preprocessor not C++.

If I'm not mistaken, one can attach a preprocessor to a compiler object 
and generate some kind of syntax tree as well as a full C AST. This 
allows some additional back-and-forth operations.
