We can enable the pager on id:

$ hg --config pager.attend-id=yes id

Pager works with shell aliases.

|

$ hg --config pager.attend-echoa=yes echoa

|
|
|
|

Pager works with hg aliases including environment variables.
|
|
|
|
|
|
$ cat >> $HGRCPATH <<'EOF'
|

|
|
|
> printa = log -T "$A\n" -r 0

|
|
paged! '1\n'
|
|
|
$ A=2 hg --config pager.attend-printa=yes printa
|
|
|
paged! '2\n'
|
|
|
|
|
|
Something that's explicitly attended is still not paginated if the
|
|
|
pager is globally set to off using a flag:
|
|
|
$ A=2 hg --config pager.attend-printa=yes printa --pager=no
|
|
|
2
|
|
|
|
|
|
Pager should not override the exit code of other commands
|
|
|
|
|
|
$ cat >> $TESTTMP/fortytwo.py <<'EOF'
|

|

A command that asks for paging using ui.pager() directly works:

|
|

paged! ' 9: a 9\n'
|
|

paged! '10: a 10\n'
|

but not with HGPLAIN
|
|
|

8: a 8
|
|
|
9: a 9

explicit flags work too:

During pushbuffer, pager should not start:
|
|
|
$ cat > $TESTTMP/pushbufferpager.py <<EOF
|
|
|

> ui.pushbuffer()
|
|
|
> ui.pager(b'mycmd')
|
|
|
> ui.write(b'content\n')
|
|
|
> ui.write(ui.popbuffer())
|
|
|
> EOF
|
|
|
|
|
|
$ echo append >> a
|
|

$ hg --config extensions.pushbuffer=$TESTTMP/pushbufferpager.py status --color=off
|
|

Environment variables like LESS and LV are set automatically:
|
|
|
$ cat > $TESTTMP/printlesslv.py <<EOF

> import os
|
|
|
> import sys
|

> sys.stdin.read()
|
|
|
> for name in ['LESS', 'LV']:
|
|
|
> sys.stdout.write(('%s=%s\n') % (name, os.environ.get(name, '-')))
|
|
|
> sys.stdout.flush()
|
|
|
> EOF
|
|
|
|
|
|
$ cat >> $HGRCPATH <<EOF
|

|
|

|
|
|
> [pager]
|
|
|
> pager = "$PYTHON" $TESTTMP/printlesslv.py
|
|

|
|
|
$ unset LESS
