Re: A better git diff --word-diff (--word-diff-regex) ?

Piotr Krukowiecki [off-list ref] writes:

is there a way to configure --word-diff to be a more programming
language friendly? For example if I add one parameter to a function
declaration, I'd like to see only the addition of the parameter as the
change. But currently it shows much more.

For example if
  void foo(int x);
is changed to
  void foo(int x, int y);
I'd like to see only ",int y" as the change, not "x, int y);".

I think I'd like to ignore all white spaces and tokenize text on word
boundaries and see the diff between the tokens. This way if I e.g. add
a missing ";" it'll be shown as the only change.

Umm, what's wrong with

  echo '*.cpp diff=cpp' >>.git/info/attributes

Ok, the funcname patterns aren't so good, but the word regex is designed
to "tokenize" as far as that is feasible.
