r8894 | '''browse command output with an external pager | ||
|
r6462 | |||
|
r9212 | To set the pager that should be used, set the application variable:: | ||
|
r6462 | |||
[pager] | ||||
pager = LESS='FSRX' less | ||||
|
r9267 | 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. | ||||
|
r6462 | |||
|
r9267 | If you notice "BROKEN PIPE" error messages, you can disable them by | ||
setting:: | ||||
|
r6462 | |||
[pager] | ||||
quiet = True | ||||
You can disable the pager for certain commands by adding them to the | ||||
|
r9212 | pager.ignore list:: | ||
|
r6462 | |||
[pager] | ||||
ignore = version, help, update | ||||
|
r9267 | You can also enable the pager only for certain commands using | ||
|
r9841 | pager.attend. Below is the default list of commands to be paged:: | ||
|
r6462 | |||
[pager] | ||||
|
r9841 | attend = annotate, cat, diff, export, glog, log, qdiff | ||
Setting pager.attend to an empty value will cause all commands to be | ||||
paged. | ||||
|
r6462 | |||
If pager.attend is present, pager.ignore will be ignored. | ||||
|
r9267 | To ignore global commands like "hg version" or "hg help", you have to | ||
specify them in the global .hgrc | ||||
