Is it possible to enable ediff features by default?

I often use ediff-directories to diff directories containing many c/c++ files. Whenever I enter a file I always '##' to ignore white space in the diff.

This becomes a problem when I have many files to diff. Is there any way to ignore white space automatically?

Solution

  • Try

    (setq-default ediff-ignore-similar-regions t)

    You may need

    (setq-default ediff-auto-refine 'on)

    as well.
