In Memory Diff
in-memory-diff
takes two source buffers and treats their content as
a set of unordered lines, as one would expect for a file like
~/.authinfo.gpg
, for example. We don't use diff(1) to diff the
buffers and thus we don't write temporary files to disk. The result is
two buffers, *A*
and *B*
. Each contains the lines the other buffer
does not contain. These files are in a major mode with the following
interesting keys bindings:
c
– copy the current line to the other source bufferk
- kill the current line from this source bufferRET
- visit the current line in this source buffer
In theory, using c
and k
on all the lines should result in the two
source containing the same lines a subsequent call of in-memory-diff
showing two empty buffers.
