Diff for "GenerateDiffBetweenRepositories"

Generate a diff between two Repositories

Usually, you can use the -p option to either incoming or outgoing. Example:

cd /path/to/repo1
hg incoming -p /path/to/repo2

Sometimes you may want a single diff. There are a number of ways to do this. We'll describe two:

a) The [:Clone:clone] method

The basic idea is to use a cheap temporary clone to do the work. If the diff is agreeable, you can then pull from your temporary clone.

MYTIP=`hg tip --template "{rev}"`
hg clone -U . tmp # make a temporary clone with no working directory
hg -R tmp pull http://remoterepo # pull the remote changes into the temporary repo
hg -R tmp diff -r $MYTIP -r tip #
rm -rf tmp

b) The [:Bundle:bundle] method

MYTIP=`hg tip --template "{rev}"`
hg in -q --bundle tmp.hg http://remoterepo && hg -R tmp.hg diff -r $MYTIP -r tip

This grabs a bundle of incoming changes then overlays the bundle on your current [:Repository:repository] (see [:LookingIntoBundles]) to generate the diff. If the diff is agreeable, you can unbundle the repo to make the changes permanent.

c) Or just use RdiffExtension and run hg diff http://remoterepo
