== Pager Extension ==
'''This extension is distributed with Mercurial.'''

''Author: [[DavidSoria|David Soria Parra]]''

=== Overview ===
Browse command output using an external pager

=== Configuration ===
Configure your [[.hgrc]] to enable the extension and set the used pager adding these lines:

{{{
  [pager]
  pager = LESS='FRX' less

  [extensions]
  pager =
}}}
If no pager is set, the pager extension uses the environment variable {{{$PAGER}}}. If neither {{{pager.pager}}}, nor {{{$PAGER}}} is set, no pager is used.

If you notice {{{BROKEN PIPE}}} error messages, you can disable them by setting:

{{{
  [pager]
  quiet = True
}}}
If you see `WARNING: terminal is not fully functional` messages (which can interfere with scripted use of Mercurial, e.g., [[http://www.gnu.org/software/tramp/|Tramp in Emacs]]), set:

{{{
  [pager]
  pager = LESS='FRX' less -d
}}}
where the `-d` argument tells `less` not to complain about 'dumb' terminals.

'''The following options are only supported by the pager extension bundled with Mercurial version 1.1 or higher:'''

You can disable the pager for certain commands (e.g., commands that are interactive) by adding them to the {{{pager.ignore}}} list:

{{{
  [pager]
  ignore = version, help, update
}}}
You can also enable the pager only for certain commands using {{{pager.attend}}}. As of Mercurial 1.4, a default attend list with the following commands is provided:

{{{
  [pager]
  attend = annotate, cat, diff, export, glog, log, qdiff
}}}
If {{{pager.attend}}} is present, the resulting behaviour will be that the pager is used for all commands listed in pager.attend, minus those which also appear in {{{pager.ignore}}} (an empty {{{pager.attend}}} with a non-empty {{{pager.ignore}}} behaves as if the above attend line was specified).

To ignore global commands like {{{hg version}}} or {{{hg help}}}, you have to specify them in the global {{{.hgrc}}}

AutopagerExtension (obsolete)

=== Comments ===
In my opinion, p (plan9's pager) is the most suitable pager for this extension. P copies its standard input to its standard output, stopping at the end of every 22nd line, and between files, to wait for a newline from the user. Thus if the output is less than 22 lines, p works just like cat. If you've p installed on your system (via [[http://swtch.com/plan9port|plan9port]]), you just need to specify it as the pager:

{{{
[pager]
pager = p
}}}
And forget about AutopagerExtension or pager.ignore.

To the author of the comment above: That's what the -F and -X switches to less achieve. They simply make it to exit if the output fits in the terminal height. Plus, -R makes it interpret the color escape sequences. Net result is a cat or a pager behavior but always with colorized output.
