Diff for "TipsAndTricks"

Make a clean copy of a source tree, like CVS export

hg clone source export
rm -rf export/.hg

The same thing, but for a tagged release

hg clone --noupdate source export-tagged
cd export-tagged
hg update mytag
rm -rf .hg

See diffs when editing commit message with VIM

Make a private copy of the 'hgeditor' script provided with mercurial and replace the call to the editor with following command:

vim "+e $HGTMP/diff" '+set buftype=help filetype=diff' "+vsplit $HGTMP/msg" || exit $?

This will start up VIM in vertical split mode with commit message in the left pane and diff in the right pane. The buftype=help setting for diff window tells vim to exit when all other windows are closed, so when you write and quit the log with :x (:wq - they are equivalent), vim exits. If you have syntax highlight set up, the diff will be properly highlighted.

This setting is suitable for wide terminals. If you have a narrow terminal, you may want to replace the +vsplit above with +split or add nowrap to the +set.

See diffstat of pulled changes

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

test -n "$NODE" || exit 0
PARENT=`hg parents $NODE | head -1 | awk -F':' '{print $3}'`
echo "diffstat for $PARENT to $NODE"
hg diff -r $PARENT -r tip | diffstat

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 repo every time you do "hg pull".
