Test template filters and functions

===================================

  $ 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'

  $ 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 phase -r 5 --public

  $ hg phase -r 7 --secret --force

  1e4e1b8f71e0

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

  1e4e1b8f71e0

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)

  >>> 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'

  foo

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

  foo

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

  $ hg debugtemplate '{"foo/bar\nbar/baz\nbar/foo\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')

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'

  0 1 4

  $ hg log -G --template '{rev}: children: {children|count}, \

  > tags: {tags|count}, file_adds: {file_adds|count}, \

  > ancestors: {revset("ancestors(%s)", rev)|count}'

  @  9: children: 0, tags: 1, file_adds: 1, ancestors: 3

  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')

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
