== See diffstat of pulled changes ==

=== Mercurial version 1.4 ===

Mercurial 1.4 includes a "hg diff --stat" option; to get a pull diffstat, add the following lines to your [[.hgrc]]:

{{{
[hooks]
changegroup=hg diff --stat -r $HG_NODE -r tip
}}}

Now you will see a diffstat of the new changes to your [[Repository|repository]] every time you do "hg pull".

If you're having problems with the above (not showing all changes or showing changes from working directory) you could try:

{{{
[hooks]
changegroup=hg log -r $HG_NODE:tip --stat --template '{empty}'
}}}

Another possibility is usage of hook, written in Python - this skips starting another instance of Mercurial is generally faster (though maybe a bit more fiddly to set up). You can find code and example how to set up [[http://mercurial.selenic.com/hg/hg/file/tip/contrib/python-hook-examples.py|here]].

=== Mercurial versions 1.3.1 and earlier ===

Place the following script (named "pull-diffstat" here) somewhere in your $PATH:

{{{
#!/bin/sh
test -n "$HG_NODE" || exit 0
TIP=`hg tip --template '{node|short}'`
REV=`hg log -r $HG_NODE --template '{rev}'`
test -n "$REV" -a $REV -ne 0 || exit 0
PREV=`expr $REV - 1`
PARENT=`hg log -r $PREV --template '{node|short}'`
echo "diffstat for $PARENT to $TIP" 1>&2
hg diff -r $PARENT -r tip | diffstat 1>&2
}}}

Add a changegroup entry to the [hooks] section of [[.hgrc]]:

{{{
[hooks]
changegroup = pull-diffstat
}}}

Now you will see a diffstat of the new changes to your [[Repository|repository]] every time you do "hg pull".

'''Note:''' When pushing to a repository that has enabled this script, the script will cause a !ValueError exception. The push will however continue and there seem to be no negative effects.
