Re: Four questions about ediff

[jonetsu]

I found ztree which is a much better way to go about making directory
diffs that the default ediff.

The points I mentioned were:

 1) Deeper comparison ?
 2) Use defaults for (some) prompts ?
 3) Accumulated diffed files in the buffer-selection
 4) Use a regex to focus on files to diff ?

1) ztree will compare files in different directories fully, so that the
very first results are showing a broad picture.  No need for the user
to manually go into each directory and ask ediff to work, often for
finding out that directories has no differences whatsoever.

2 and 3) ztree still uses the traditional diff to make file compares.
It will ask if the user wants to close unmodified files when exiting a
diff.  It will not ask about modified files, leaving it to the user to
save them, which is OK.

4) So far - short time - not sure if that's supported.  Eg. being able
to compare only, say, .mk files.

A very welcomed find, a much more useful and productive way to compare
directories.
