Age filter:

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

  >>> import datetime
  >>> fp = open('a', 'wb')
  >>> n = datetime.datetime.now() + datetime.timedelta(366 * 7)

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

  $ 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')
  [10]

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'

  $ hg log -l1 -T '{termwidth|count}\n'
  hg: parse error: not countable
  (template filter 'count' is not compatible with keyword 'termwidth')
  [10]

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

Test filter() shouldn't crash:

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

  hg: parse error: filter expects one or two arguments
  [10]
  $ hg log -R a -r 0 -T '{filter(date)}\n'

  $ 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'

  $ hg log -R latesttag -r tip -T '{join(get(extras, "branch"), ".")}\n'

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'

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)

pad() with truncate has to strip color codes, though

  $ hg debugtemplate --color=always \
  > '{pad(label(red, "scarlet"), 5, truncate=true)}\n'
  scarl

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")}'

a revset item must be evaluated as an integer revision, not an offset from tip

  $ hg log -l 1 -T '{revset("null") % "{rev}:{node|short}"}\n'
  -1:000000000000
  $ hg log -l 1 -T '{revset("%s", "null") % "{rev}:{node|short}"}\n'
  -1:000000000000

join() should pick '{rev}' from revset items:

  $ hg log -R ../a -T '{join(revset("parents(%d)", rev), ", ")}\n' -r6
  4, 5

on the other hand, parents are formatted as '{rev}:{node|formatnode}' by
default. join() should agree with the default formatting:

  $ hg log -R ../a -T '{join(parents, ", ")}\n' -r6
  5:13207e5a10d9, 4:bbe44766e73d

  $ hg log -R ../a -T '{join(parents, ",\n")}\n' -r6 --debug

for historical reasons, revset() supports old-style list template

  $ hg log -T '{revset(":")}\n' -l1 \

  >        --config templates.end_revisions='"]"' \

  [0, 1, 2]
  $ hg log -T '{revset(":") % " {revision}"}\n' -l1

but a filtered one doesn't

  $ hg log -T '{filter(revset(":"), ifeq(rev, 1, "", "y"))}\n' -l1 \

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

  > 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"

cbor filter is bytes transparent, which should handle bytes subtypes
as bytes:

  $ HGENCODING=ascii hg log -T "{branch|cbor}" -r0 \

  ]
  $ HGENCODING=latin-1 hg log -T "{branch|cbor}" -r0 \

  [

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)

  $ hg log -T "coerced to string: {rev|utf8}\n" -r0
