Binary diff in Mercurial

To do this you can use the extdiff extension with the vbindiff program (available in Ubuntu).

Edit your Mercurial config (~/.hgrc) to include the following lines:

[extensions]
extdiff =

[extdiff]
cmd.bdiff = vbindiff

Now you can get a diff of a binary file with the following command:

$ hg bdiff <filename>
