Signature

(smerge-refine-subst BEG1 END1 BEG2 END2 PROPS-C &optional PREPROC PROPS-R PROPS-A)

Documentation

Show fine differences in the two regions BEG1..END1 and BEG2..END2.

PROPS-C is an alist of properties to put (via overlays) on the changes. PROPS-R is an alist of properties to put on removed characters. PROPS-A is an alist of properties to put on added characters. If PROPS-R and PROPS-A are nil, put PROPS-C on all changes. If PROPS-C is nil, but PROPS-R and PROPS-A are non-nil, put PROPS-A on added characters, PROPS-R on removed characters. If PROPS-C, PROPS-R and PROPS-A are non-nil, put PROPS-C on changed characters, PROPS-A on added characters, and PROPS-R on removed characters.

If non-nil, PREPROC is called with no argument in a buffer that contains a copy of a region, just before preparing it to for diff. It can be used to replace chars to try and eliminate some spurious differences. The two regions can be in different buffers (in which case, BEG1 and BEG2 need to be markers to indicate the corresponding buffers).
