ui: capture push location on path instances
Currently, we treat "default" and "default-push" as separate paths,
even though they are the same logical entity but with different paths
for different operations. Because they are the same entity and
because we will eventually be implementing an official mechanism
for declaring push URLs for paths, we establish a "pushloc" attribute
on path instances. We populate this attribute on the "default" path
with the "default-push" value, if present. This will enable
consumers stop referencing "default-push" which will make their code
simpler.

# pager.py - display output using a pager # # Copyright 2008 David Soria Parra <dsp@php.net> # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. # # To load the extension, add it to your configuration file: # # [extension] # pager = # # Run "hg help pager" to get info on configuration. '''browse command output with an external pager To set the pager that should be used, set the application variable:: [pager] pager = less -FRX If no pager is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager is used. You can disable the pager for certain commands 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. Below is the default list of commands to be paged:: [pager] attend = annotate, cat, diff, export, glog, log, qdiff Setting pager.attend to an empty value will cause all commands to be paged. If pager.attend is present, pager.ignore will be ignored. Lastly, you can enable and disable paging for individual commands with the attend-<command> option. This setting takes precedence over existing attend and ignore options and defaults:: [pager] attend-cat = false To ignore global commands like :hg:`version` or :hg:`help`, you have to specify them in your user configuration file. The --pager=... option can also be used to control when the pager is used. Use a boolean value like yes, no, on, off, or use auto for normal behavior.
