Mercurial allows you to customize output of commands through
templates. You can either pass in a template from the command
line, via the --template option, or select an existing
template-style (--style).
You can customize output for any "log-like" command: log,
outgoing, incoming, tip, parents, heads and glog.
Four styles are packaged with Mercurial: default (the style used
when no explicit preference is passed), compact, changelog,
and xml.
Usage::
$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable
expansion::
$ hg log -r1 --template "{node}\n"

Strings in curly braces are called keywords. The availability of
keywords depends on the exact context of the templater. These
keywords are usually available for templating a log-like command:
:author: String. The unmodified author of the changeset.
:branches: String. The name of the branch on which the changeset was
committed. Will be empty if the branch name was default.
:date: Date information. The date when the changeset was committed.
:desc: String. The text of the changeset description.
:diffstat: String. Statistics of changes with the following format:
"modified files: +added/-removed lines"
:files: List of strings. All files modified, added, or removed by this
changeset.
:file_adds: List of strings. Files added by this changeset.
:file_copies: List of strings. Files copied in this changeset with
their sources.
:file_copies_switch: List of strings. Like "file_copies" but displayed
only if the --copied switch is set.
:file_mods: List of strings. Files modified by this changeset.
:file_dels: List of strings. Files removed by this changeset.
:node: String. The changeset identification hash, as a 40-character
hexadecimal string.
:parents: List of strings. The parents of the changeset.
:rev: Integer. The repository-local changeset revision number.
:tags: List of strings. Any tags associated with the changeset.
:latesttag: String. Most recent global tag in the ancestors of this
changeset.
:latesttagdistance: Integer. Longest path to the latest tag.
The "date" keyword does not produce human-readable output. If you
want to use a date in your output, you can use a filter to process
it. Filters are functions which return a string based on the input
variable. Be sure to use the stringify filter first when you're
applying a string-input filter to a list-like input variable.
You can also use a chain of filters to get the desired output::
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
List of filters:
:addbreaks: Any text. Add an XHTML "<br />" tag before the end of
every line except the last.
:age: Date. Returns a human-readable date/time difference between the
given date/time and the current date/time.
:basename: Any text. Treats the text as a path, and returns the last
component of the path after splitting by the path separator
(ignoring trailing separators). For example, "foo/bar/baz" becomes
"baz" and "foo/bar//" becomes "bar".
:stripdir: Treat the text as path and strip a directory level, if
possible. For example, "foo" and "foo/bar" becomes "foo".
:date: Date. Returns a date in a Unix date format, including the
timezone: "Mon Sep 04 15:13:13 2006 0700".
:domain: Any text. Finds the first string that looks like an email
address, and extracts just the domain component. Example: ``User
<user@example.com>`` becomes ``example.com``.
:email: Any text. Extracts the first string that looks like an email
address. Example: ``User <user@example.com>`` becomes
``user@example.com``.
:escape: Any text. Replaces the special XML/XHTML characters "&", "<"
and ">" with XML entities.
:fill68: Any text. Wraps the text to fit in 68 columns.
:fill76: Any text. Wraps the text to fit in 76 columns.
:firstline: Any text. Returns the first line of text.
:nonempty: Any text. Returns '(none)' if the string is empty.
:hgdate: Date. Returns the date as a pair of numbers: "1157407993
25200" (Unix timestamp, timezone offset).
:isodate: Date. Returns the date in ISO 8601 format: "2009-08-18 13:00
+0200".
:isodatesec: Date. Returns the date in ISO 8601 format, including
seconds: "2009-08-18 13:00:13 +0200". See also the rfc3339date
filter.
:localdate: Date. Converts a date to local date.
:obfuscate: Any text. Returns the input text rendered as a sequence of
XML entities.
:person: Any text. Returns the text before an email address.
:rfc822date: Date. Returns a date using the same format used in email
headers: "Tue, 18 Aug 2009 13:00:13 +0200".
:rfc3339date: Date. Returns a date using the Internet date format
specified in RFC 3339: "2009-08-18T13:00:13+02:00".
:short: Changeset hash. Returns the short form of a changeset hash,
i.e. a 12-byte hexadecimal string.
:shortdate: Date. Returns a date like "2006-09-18".
:strip: Any text. Strips all leading and trailing whitespace.
:tabindent: Any text. Returns the text, with every line except the
