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 Extension
This extension is distributed with Mercurial.
Author: David Soria Parra
This extension does not work reliably on Windows. See bug 1677.
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='FSRX' 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
The following options are only supported by the pager extension bundled with Mercurial version 1.1 or higher:
If you see WARNING: terminal is not fully functional messages (which can interfere with scripted use of Mercurial, e.g., Tramp in Emacs), set:
[pager] pager = LESS='FSRX' less -d
where the -d argument tells less not to complain about 'dumb' terminals.
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
