git show equivalent in Mercurial

What would be the equivalent of git show in Mercurial ? I am mostly after the diff between given changeset and its parent, not necessarily the changeset metadata.

Ideally expressed as alias in hgrc.

Edit: since hg show is now a core-provided extension, it's probably wise to pick another name. See also Reimer Behrends' answer and the comments there.

I have a tiny script I use. It is not terribly clever but it lets you use a git show <rev> or git show (to see HEAD / .) as hg show:

[alias]
show = !hg-show "$@"

where hg-show is:

#! /bin/sh

# hg-show - helper script for "hg show"

case $# in
0) $HG log -pv -r .;;
1) $HG log -pv -r "$1";;
*) $HG log -pv "$@";;
esac

It should be easy enough to put the entire script into the alias, if you prefer that. I had planned to make the script fancier someday, but have not been using Mercurial for several years now. (I first wrote the above script itself probably sometime around 2013.)

To see the diff for a commit, simply use hg diff -c REV. You can also specify the first and last revision by using -r twice, e.g. hg diff -r REV^ -r REV.

As an alias, just use:

[alias]
show = diff -c

(Note that show is already a Mercurial command, so you may want to pick a different name.)

Alternatively, hg log -p or hg export can also be used if you need to see the commit metadata as well, but hg diff -c allows you to use the regular diff options, e.g. to ignore whitespace.

For a revision range, you can use the :: revset operator. hg diff -r 'REV^::REV' works as well (see hg help revsets for more information on how to express non-trivial revision sets).
