Hello,
Is it possible to access the local indentation character(s), i.e. tab
or whatever number of spaces, from coccilib in Python?
I'd like to print lines of code underlined with carets, a la clang,
from within a @script:python@.
What is accessible in python is the value of metavariable, and
metavariables are bound to terms without information about their spacing
so that they can match to other terms that look the same but have
different spacing.
What you can do is put a position variable on the first token in your
pattern. Then the starting column will indicate the indentation. But the
indentation will be the number of characters, which might be spaces
or might be tabs. It could be possible to store the preceding whitespace
in a position variable.
I'm not familiar with what clang does. Is the goal to highlight matched
code? Perhaps tere is some separate highlighting tool you can use that
will take as input the position information? I use org mode in emacs.
