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" b56ce7b07c52de7d5fd79fb89701ea538af65746 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. :children: List of strings. The children of the changeset. :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 hexadecimal digit 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 "
" 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 `` becomes ``example.com``. :email: Any text. Extracts the first string that looks like an email address. Example: ``User `` becomes ``user@example.com``. :escape: Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML entities. :hex: Any text. Convert a binary Mercurial node identifier into its long hexadecimal representation. :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 hexadecimal digit string. :shortdate: Date. Returns a date like "2006-09-18". :stringify: Any type. Turns the value into text by converting values into text and concatenating them. :strip: Any text. Strips all leading and trailing whitespace. :tabindent: Any text. Returns the text, with every line except the first starting with a tab character. :urlescape: Any text. Escapes all "special" characters. For example, "foo bar" becomes "foo%20bar". :user: Any text. Returns the user portion of an email address.
