Enable ui.assume-tty so that the pager will start, and set the pager to our
|

fake pager that lets us see when the pager was running.

We can enable the pager on id:
|
|
|
|
BROKEN: should be paged
|
|
$ hg --config pager.attend-id=yes id

Setting attend-$COMMAND to a false value works, even with pager in
|
|
core:
|
|
$ hg --config pager.attend-diff=no diff -c 2

Attend for an abbreviated command does not work
|
|
|
|
$ hg --config pager.attend-ident=true ident
|
|
46106edeeb38
|
|
|
|
Pager should not start if stdout is not a tty.
|
|
|

$ hg log -l1 -q --config ui.assume-tty=no
|

|

Pager should be disabled if pager.pager is empty (otherwise the output would
|
|
be silently lost.)
|

$ hg log -l1 -q --config pager.pager=
|

Pager with color enabled allows colors to come through by default,

even though stdout is no longer a tty.

An invalid pager command name is reported sensibly if we don't have to
|
|
use shell=True in the subprocess call:
|
|
$ hg log --limit 3 --config pager.pager=this-command-better-never-exist
|
|
missing pager command 'this-command-better-never-exist', skipping pager

A complicated pager command gets worse behavior. Bonus points if you can
|
|
improve this.

Pager works with shell aliases.
|
|
|
|
$ cat >> $HGRCPATH <<EOF
|
|
> [alias]
|
|
> echoa = !echo a
|
|
> EOF
|
|
|
|
$ hg echoa
|
|
a
|
|
BROKEN: should be paged
|
|
$ hg --config pager.attend-echoa=yes echoa
|
|

|
|
|
|
Pager works with hg aliases including environment variables.
|
|
|
|
$ cat >> $HGRCPATH <<'EOF'
|
|
> [alias]
|
|
> printa = log -T "$A\n" -r 0
|

|
$ A=1 hg --config pager.attend-printa=yes printa
|
|
paged! '$A\n'
|
|
$ A=2 hg --config pager.attend-printa=yes printa
|
|
paged! '$A\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
|
|
$A
|
|
|
|
Pager should not override the exit code of other commands
|
|
|
|
$ cat >> $TESTTMP/fortytwo.py <<'EOF'
|
|
> from edenscm.mercurial import commands, registrar
|
|
> cmdtable = {}
|
|
> command = registrar.command(cmdtable)
|
|
> @command('fortytwo', [], 'fortytwo', norepo=True)
|
|
> def fortytwo(ui, *opts):
|
|
> ui.write('42\n')

|
|
|
|
$ hg fortytwo --pager=on
|
|
paged! '42\n'
|
|
[42]
|
|
|
|
A command that asks for paging using ui.pager() directly works:
|
|
$ hg blame --color=no a
|
|
paged! ' 0: a\n'
|
|
paged! ' 1: a 1\n'
|
|
paged! ' 2: a 2\n'
|
|
paged! ' 3: a 3\n'
|
|
paged! ' 4: a 4\n'
|
|
paged! ' 5: a 5\n'
|
|
paged! ' 6: a 6\n'
|
|
paged! ' 7: a 7\n'
|
|
paged! ' 8: a 8\n'
|
|
paged! ' 9: a 9\n'
|
|
paged! '10: a 10\n'
|
|
but not with HGPLAIN
|
|
$ HGPLAIN=1 hg blame a
|
|
0: a
|
|
1: a 1
|
|
2: a 2
|
|
3: a 3
|
|
4: a 4
|
|
5: a 5
|
|
6: a 6
|
|
7: a 7
|
|
8: a 8
|
|
9: a 9
|
|
10: a 10
|
|
explicit flags work too:
|
|
$ hg blame --pager=no --color=no a
|
|
0: a
|
|
1: a 1
|
|
2: a 2
|
|
3: a 3
|
|
4: a 4
|
|
5: a 5
|
|
6: a 6
|
|
7: a 7
|
|
8: a 8
|
|
9: a 9
|
|
10: a 10
|
|
|
|
A command with --output option:
|
|
|
|
$ hg cat -r0 a
|
|
paged! 'a\n'
|
|
$ hg cat -r0 a --output=-
|
|
paged! 'a\n'
|
|
$ hg cat -r0 a --output=out
|
|
$ rm out
|
|

During pushbuffer, pager should not start:
