'''browse command output with an external pager To set the pager that should be used, set the application variable:: [pager] pager = LESS='FSRX' less 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. If you notice "BROKEN PIPE" error messages, you can disable them by setting:: [pager] quiet = True 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. To ignore global commands like "hg version" or "hg help", you have to specify them in the global .hgrc ''' import sys, os, signal from mercurial import dispatch, util, extensions def uisetup(ui): def pagecmd(orig, ui, options, cmd, cmdfunc): p = ui.config("pager", "pager", os.environ.get("PAGER")) if p and sys.stdout.isatty() and '--debugger' not in sys.argv: attend = ui.configlist('pager', 'attend', attended) if (cmd in attend or (cmd not in ui.configlist('pager', 'ignore') and not attend)): ui.setconfig('ui', 'interactive', False) sys.stderr = sys.stdout = util.popen(p, "wb") if ui.configbool('pager', 'quiet'): signal.signal(signal.SIGPIPE, signal.SIG_DFL) return orig(ui, options, cmd, cmdfunc) extensions.wrapfunction(dispatch, '_runcommand', pagecmd) attended = ['annotate', 'cat', 'diff', 'export', 'glog', 'log', 'qdiff']
