Lint can't catch the indentation format, and Question about offical docs for google style guide #230

I expected lint will be catch the no indentation in code, but lint can't catch it.
so i search for google offical docs for style guide, and there was only sentence for space and identation for 2 space.

Does style guide not defining about no ident? or the 2 space indent is to essential, so it didn't implemented in cpplint

If this is just not implemented function, i want to leave issue for adding that function.
