tests/test-command-template.t

templates-default: do not show description or summary if empty

changeset_printer shows description only if ctx.description().strip() is not
empty. The default template should do the same way.

  $ hg init a
  $ cd a
  $ echo a > a
  $ hg add a
  $ echo line 1 > b
  $ echo line 2 >> b
  $ hg commit -l b -d '1000000 0' -u 'User Name <user@hostname>'

  $ hg add b
  $ echo other 1 > c
  $ echo other 2 >> c
  $ echo >> c
  $ echo other 3 >> c
  $ hg commit -l c -d '1100000 0' -u 'A. N. Other <other@place>'

  $ hg add c
  $ hg commit -m 'no person' -d '1200000 0' -u 'other@place'
  $ echo c >> c
  $ hg commit -m 'no user, no domain' -d '1300000 0' -u 'person'

  $ echo foo > .hg/branch
  $ hg commit -m 'new branch' -d '1400000 0' -u 'person'

  $ hg co -q 3
  $ echo other 4 >> d
  $ hg add d
  $ hg commit -m 'new head' -d '1500000 0' -u 'person'

  $ hg merge -q foo
  $ hg commit -m 'merge' -d '1500001 0' -u 'person'

Second branch starting at nullrev:

  $ hg update null
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ echo second > second
  $ hg add second
  $ hg commit -m second -d '1000000 0' -u 'User Name <user@hostname>'
  created new head

  $ echo third > third
  $ hg add third
  $ hg mv second fourth
  $ hg commit -m third -d "2020-01-01 10:01"

  $ hg log --template '{join(file_copies, ",\n")}\n' -r .
  fourth (second)
  $ hg log -T '{file_copies % "{source} -> {name}\n"}' -r .
  second -> fourth
  $ hg log -T '{rev} {ifcontains("fourth", file_copies, "t", "f")}\n' -r .:7
  8 t
  7 f

Quoting for ui.logtemplate

  $ hg tip --config "ui.logtemplate={rev}\n"
  8
  $ hg tip --config "ui.logtemplate='{rev}\n'"
  8
  $ hg tip --config 'ui.logtemplate="{rev}\n"'
  8

Make sure user/global hgrc does not affect tests

  $ echo '[ui]' > .hg/hgrc
  $ echo 'logtemplate =' >> .hg/hgrc
  $ echo 'style =' >> .hg/hgrc

Add some simple styles to settings

  $ echo '[templates]' >> .hg/hgrc
  $ printf 'simple = "{rev}\\n"\n' >> .hg/hgrc
  $ printf 'simple2 = {rev}\\n\n' >> .hg/hgrc

  $ hg log -l1 -Tsimple
  8
  $ hg log -l1 -Tsimple2
  8

Test templates and style maps in files:

  $ echo "{rev}" > tmpl
  $ hg log -l1 -T./tmpl
  8
  $ hg log -l1 -Tblah/blah
  blah/blah (no-eol)

  $ printf 'changeset = "{rev}\\n"\n' > map-simple
  $ hg log -l1 -T./map-simple
  8

Template should precede style option

  $ hg log -l1 --style default -T '{rev}\n'
  8

Default style is like normal output:

  $ echo c >> c
  $ hg add c
  $ hg commit -qm ' '

  $ hg log > log.out
  $ hg log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -v > log.out
  $ hg log -v --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -q > log.out
  $ hg log -q --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log --debug > log.out
  $ hg log --debug --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

Default style should also preserve color information (issue2866):

  $ cp $HGRCPATH $HGRCPATH-bak
  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > color=
  > EOF

  $ hg --color=debug log > log.out
  $ hg --color=debug log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug -v log > log.out
  $ hg --color=debug -v log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug -q log > log.out
  $ hg --color=debug -q log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg --color=debug --debug log > log.out
  $ hg --color=debug --debug log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ mv $HGRCPATH-bak $HGRCPATH

  $ hg --config extensions.strip= strip -q .

Revision with no copies (used to print a traceback):

  $ hg tip -v --template '\n'
  

Compact style works:

  $ hg log -Tcompact

Missing non-standard names give no error (backward compatibility):

  $ echo "changeset = '{c}'" > t
