  $ echo second > second
  $ hg add second
  $ hg commit -m second -d '1000000 0' -u 'User Name <user@hostname>'

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

  $ hg phase -r 5 --public

Formatnode filter works:

  1e4e1b8f71e0

  $ hg log -r 0 --template '{node|formatnode}\n'
  1e4e1b8f71e0

  1e4e1b8f71e05681d422154f5421e385fec3454f

Age filter:

  $ hg init unstable-hash
  $ cd unstable-hash
  $ hg log --template '{date|age}\n' > /dev/null || exit 1

  >>> from __future__ import absolute_import
  >>> import datetime
  >>> fp = open('a', 'wb')
  >>> n = datetime.datetime.now() + datetime.timedelta(366 * 7)
  >>> fp.write(b'%d-%d-%d 00:00' % (n.year, n.month, n.day)) and None
  >>> fp.close()
  $ hg add a
  $ hg commit -m future -d "`cat a`"

  $ hg log -l1 --template '{date|age}\n'
  7 years from now

  $ cd ..
  $ rm -rf unstable-hash

Filename filters:

  $ hg debugtemplate '{"foo/bar"|basename}|{"foo/"|basename}|{"foo"|basename}|\n'
  bar||foo|
  $ hg debugtemplate '{"foo/bar"|dirname}|{"foo/"|dirname}|{"foo"|dirname}|\n'
  foo|foo||
  $ hg debugtemplate '{"foo/bar"|stripdir}|{"foo/"|stripdir}|{"foo"|stripdir}|\n'
  foo|foo|foo|

commondir() filter:

  $ hg debugtemplate '{""|splitlines|commondir}\n'
  
  $ hg debugtemplate '{"foo/bar\nfoo/baz\nfoo/foobar\n"|splitlines|commondir}\n'
  foo
  $ hg debugtemplate '{"foo/bar\nfoo/bar\n"|splitlines|commondir}\n'

  $ hg debugtemplate '{"foo/../bar\nfoo/bar"|splitlines|commondir}\n'
  foo
  $ hg debugtemplate '{"foo\n/foo"|splitlines|commondir}\n'
  

  $ hg log -r null -T '{rev|commondir}'
  hg: parse error: argument is not a list of text
  (template filter 'commondir' is not compatible with keyword 'rev')
  [255]

Add a dummy commit to make up for the instability of the above:

  $ echo a > a
  $ hg add a
  $ hg ci -m future

Count filter:

  $ hg log -l1 --template '{node|count} {node|short|count}\n'
  40 12

  $ hg log -l1 --template '{revset("null^")|count} {revset(".")|count} {revset("0::3")|count}\n'

  |
  o  0: children: 1, tags: 0, file_adds: 1, ancestors: 1
  

  $ hg log -l1 -T '{termwidth|count}\n'
  hg: parse error: not countable
  (template filter 'count' is not compatible with keyword 'termwidth')
  [255]

Upper/lower filters:

  $ hg log -r0 --template '{branch|upper}\n'
  DEFAULT
  $ hg log -r0 --template '{author|lower}\n'
  user name <user@hostname>
  $ hg log -r0 --template '{date|upper}\n'
  1000000.00

Add a commit that does all possible modifications at once

  $ echo modify >> third
  $ touch b
  $ hg add b
  $ hg mv fourth fifth
  $ hg rm a
  $ hg ci -m "Modify, add, remove, rename"

Pass generator object created by template function to filter

  $ hg log -l 1 --template '{if(author, author)|user}\n'
  test

Test filter() empty values:

  $ hg log -R a -r 1 -T '{filter(desc|splitlines) % "{line}\n"}'
  other 1
  other 2
  other 3
  $ hg log -R a -r 0 -T '{filter(dict(a=0, b=1) % "{ifeq(key, "a", "{value}\n")}")}'
  0

 0 should not be falsy

  $ hg log -R a -r 0 -T '{filter(revset("0:2"))}\n'
  0 1 2

Test filter() by expression:

  $ hg log -R a -r 1 -T '{filter(desc|splitlines, ifcontains("1", line, "t"))}\n'
  other 1
  $ hg log -R a -r 0 -T '{filter(dict(a=0, b=1), ifeq(key, "b", "t"))}\n'
  b=1

Test filter() shouldn't crash:

  branch=default
  $ hg log -R a -r 0 -T '{filter(files)}\n'
  a

Test filter() unsupported arguments:

  hg: parse error: filter expects one or two arguments
  [255]
  $ hg log -R a -r 0 -T '{filter(date)}\n'
  hg: parse error: date is not iterable
  [255]
  $ hg log -R a -r 0 -T '{filter(rev)}\n'
  hg: parse error: 0 is not iterable

Test manifest/get() can be join()-ed as string, though it's silly:

  $ hg log -R latesttag -r tip -T '{join(manifest, ".")}\n'
  1.1.:.2.b.c.6.e.9.0.0.6.c.e.2
  $ hg log -R latesttag -r tip -T '{join(get(extras, "branch"), ".")}\n'
  d.e.f.a.u.l.t

Test join() over string

  $ hg log -R latesttag -r tip -T '{join(rev|stringify, ".")}\n'
  1.1

Test join() over uniterable

  $ hg log -R latesttag -r tip -T '{join(rev, "")}\n'
  hg: parse error: 11 is not iterable
  [255]

Test min/max of integers

  $ hg log -R latesttag -l1 -T '{min(revset("9:10"))}\n'
  9
  $ hg log -R latesttag -l1 -T '{max(revset("9:10"))}\n'

Test min/max of strings:

  $ hg log -R latesttag -l1 -T '{min(desc)}\n'

  [255]
  $ hg debugtemplate '{max(2)}'

Test min/max of if() result

  $ cd latesttag

  9
  $ hg log -l1 -T '{max(if(false, "", revset("9:10")))}\n'

  9
  $ hg log -l1 -T '{max(ifeq(0, 1, "", revset("9:10")))}\n'
  10
  $ cd ..

Test laziness of if() then/else clause

  $ hg debugtemplate '{count(0)}'
  hg: parse error: not countable
  (incompatible use of template filter 'count')
  [255]
  $ hg debugtemplate '{if(true, "", count(0))}'

  $ hg debugtemplate '{ifeq(0, 0, "", count(0))}'
  $ hg debugtemplate '{ifeq(0, 1, count(0), "")}'

Test the sub function of templating for expansion:

  $ hg log -R latesttag -r 10 --template '{sub("[0-9]", "x", "{rev}")}\n'
  xx

  $ hg log -R latesttag -r 10 -T '{sub("[", "x", rev)}\n'
  hg: parse error: sub got an invalid pattern: [

Test date format:

  $ hg log -R latesttag --template 'date: {date(date, "%y %m %d %S %z")}\n'
  date: 70 01 01 10 +0000
  date: 70 01 01 09 +0000

Set up repository containing template fragments in commit metadata:

  $ hg init r
  $ cd r
  $ echo a > a
  $ hg ci -Am '{rev}'
  adding a

  $ hg branch -q 'text.{rev}'
  $ echo aa >> aa
  $ hg ci -u '{node|short}' -m 'desc to be wrapped desc to be wrapped'

color effect can be specified without quoting:

  $ hg log --color=always -l 1 --template '{label(red, "text\n")}'
  \x1b[0;31mtext\x1b[0m (esc)

color effects can be nested (issue5413)

  $ hg debugtemplate --color=always \
  > '{label(red, "red{label(magenta, "ma{label(cyan, "cyan")}{label(yellow, "yellow")}genta")}")}\n'
  \x1b[0;31mred\x1b[0;35mma\x1b[0;36mcyan\x1b[0m\x1b[0;31m\x1b[0;35m\x1b[0;33myellow\x1b[0m\x1b[0;31m\x1b[0;35mgenta\x1b[0m (esc)

pad() should interact well with color codes (issue5416)

  $ hg debugtemplate --color=always \
  > '{pad(label(red, "red"), 5, label(cyan, "-"))}\n'
  \x1b[0;31mred\x1b[0m\x1b[0;36m-\x1b[0m\x1b[0;36m-\x1b[0m (esc)

label should be no-op if color is disabled:

  $ hg log --color=never -l 1 --template '{label(red, "text\n")}'
  text
  $ hg log --config extensions.color=! -l 1 --template '{label(red, "text\n")}'
  text

Test word error messages for not enough and too many arguments

  $ hg log -Gv -R a --template "{word('0')}"
  hg: parse error: word expects two or three arguments, got 1

json filter should escape HTML tags so that the output can be embedded in hgweb:

  $ hg log -T "{'<[e-mail]>'|json}\n" -R a -l1
  "\[e-mail]\u003e"

Set up repository for non-ascii encoding tests:

  $ hg init nonascii
  $ cd nonascii
  $ $PYTHON <<EOF
  > open('latin1', 'wb').write(b'\xe9')
  > open('utf-8', 'wb').write(b'\xc3\xa9')
  > EOF
  $ HGENCODING=utf-8 hg branch -q `cat utf-8`
  $ HGENCODING=utf-8 hg ci -qAm "non-ascii branch: `cat utf-8`" utf-8

json filter should try round-trip conversion to utf-8:

  $ HGENCODING=ascii hg log -T "{branch|json}\n" -r0
  "\u00e9"
  $ HGENCODING=ascii hg log -T "{desc|json}\n" -r0
  "non-ascii branch: \u00e9"

json filter should take input as utf-8 if it was converted from utf-8:

  $ HGENCODING=latin-1 hg log -T "{branch|json}\n" -r0
  "\u00e9"
  $ HGENCODING=latin-1 hg log -T "{desc|json}\n" -r0
  "non-ascii branch: \u00e9"

json filter takes input as utf-8b:

  $ HGENCODING=ascii hg log -T "{'`cat utf-8`'|json}\n" -l1
  "\u00e9"
  $ HGENCODING=ascii hg log -T "{'`cat latin1`'|json}\n" -l1
  "\udce9"

utf8 filter:

  $ HGENCODING=ascii hg log -T "round-trip: {branch|utf8|hex}\n" -r0
  round-trip: c3a9
  $ HGENCODING=latin1 hg log -T "decoded: {'`cat latin1`'|utf8|hex}\n" -l1
  decoded: c3a9
  $ HGENCODING=ascii hg log -T "replaced: {'`cat latin1`'|utf8|hex}\n" -l1
  abort: decoding near * (glob)
  [255]
  $ hg log -T "coerced to string: {rev|utf8}\n" -r0
  coerced to string: 0

pad width:

  $ HGENCODING=utf-8 hg debugtemplate "{pad('`cat utf-8`', 2, '-')}\n"
  \xc3\xa9- (esc)

  $ cd ..
