Test arithmetic operators have the right precedence:

  $ hg log -l 1 -T '{date(date, "%Y") + 5 * 10} {date(date, "%Y") - 2 * 3}\n'
  2020 1964
  $ hg log -l 1 -T '{date(date, "%Y") * 5 + 10} {date(date, "%Y") * 3 - 2}\n'
  9860 5908

Test division:

  $ hg debugtemplate -r0 -v '{5 / 2} {mod(5, 2)}\n'
  (template
    (/
      (integer '5')
      (integer '2'))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (integer '5')
        (integer '2')))
    (string '\n'))
  2 1
  $ hg debugtemplate -r0 -v '{5 / -2} {mod(5, -2)}\n'
  (template
    (/
      (integer '5')
      (negate
        (integer '2')))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (integer '5')
        (negate
          (integer '2'))))
    (string '\n'))
  -3 -1
  $ hg debugtemplate -r0 -v '{-5 / 2} {mod(-5, 2)}\n'
  (template
    (/
      (negate
        (integer '5'))
      (integer '2'))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (negate
          (integer '5'))
        (integer '2')))
    (string '\n'))
  -3 1
  $ hg debugtemplate -r0 -v '{-5 / -2} {mod(-5, -2)}\n'
  (template
    (/
      (negate
        (integer '5'))
      (negate
        (integer '2')))
    (string ' ')
    (func
      (symbol 'mod')
      (list
        (negate
          (integer '5'))
        (negate
          (integer '2'))))
    (string '\n'))
  2 -1

Filters bind closer than arithmetic:

  $ hg debugtemplate -r0 -v '{revset(".")|count - 1}\n'
  (template
    (-
      (|
        (func
          (symbol 'revset')
          (string '.'))
        (symbol 'count'))
      (integer '1'))
    (string '\n'))
  0

But negate binds closer still:

  $ hg debugtemplate -r0 -v '{1-3|stringify}\n'
  (template
    (-
      (integer '1')
      (|
        (integer '3')
        (symbol 'stringify')))
    (string '\n'))
  hg: parse error: arithmetic only defined on integers
  [255]
  $ hg debugtemplate -r0 -v '{-3|stringify}\n'
  (template
    (|
      (negate
        (integer '3'))
      (symbol 'stringify'))
    (string '\n'))
  -3

Filters bind as close as map operator:

  $ hg debugtemplate -r0 -v '{desc|splitlines % "{line}\n"}'
  (template
    (%
      (|
        (symbol 'desc')
        (symbol 'splitlines'))
      (template
        (symbol 'line')
        (string '\n'))))
  line 1
  line 2

Keyword arguments:

  $ hg debugtemplate -r0 -v '{foo=bar|baz}'
  (template
    (keyvalue
      (symbol 'foo')
      (|
        (symbol 'bar')
        (symbol 'baz'))))
  hg: parse error: can't use a key-value pair in this context
  [255]

  $ hg debugtemplate '{pad("foo", width=10, left=true)}\n'
         foo

Call function which takes named arguments by filter syntax:

  $ hg debugtemplate '{" "|separate}'
  $ hg debugtemplate '{("not", "an", "argument", "list")|separate}'
  hg: parse error: unknown method 'list'
  [255]

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

Working-directory revision has special identifiers, though they are still
experimental:

  $ hg log -r 'wdir()' -T '{rev}:{node}\n'
  2147483647:ffffffffffffffffffffffffffffffffffffffff

Some keywords are invalid for working-directory revision, but they should
never cause crash:

  $ hg log -r 'wdir()' -T '{manifest}\n'
  

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
  $ hg tip --config 'ui.logtemplate=n{rev}\n'
  n8

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

  $ cat <<'EOF' >> .hg/hgrc
  > [templates]
  > simple = "{rev}\n"
  > simple2 = {rev}\n
  > rev = "should not precede {rev} keyword\n"
  > EOF

  $ hg log -l1 -Tsimple
  8
  $ hg log -l1 -Tsimple2
  8
  $ hg log -l1 -Trev
  should not precede 8 keyword
  $ hg log -l1 -T '{simple}'
  8

Map file shouldn't see user templates:

  $ cat <<EOF > tmpl
  > changeset = 'nothing expanded:{simple}\n'
  > EOF
  $ hg log -l1 --style ./tmpl
  nothing expanded:

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

Test template map inheritance

  $ echo "__base__ = map-cmdline.default" > map-simple
  $ printf 'cset = "changeset: ***{rev}***\\n"\n' >> map-simple
  $ hg log -l1 -T./map-simple
  changeset: ***8***

Test docheader, docfooter and separator in template map

  $ cat <<'EOF' > map-myjson
  > docheader = '\{\n'
  > docfooter = '\n}\n'
  > separator = ',\n'
  > changeset = ' {dict(rev, node|short)|json}'
  > EOF
  $ hg log -l2 -T./map-myjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }

Test docheader, docfooter and separator in [templates] section

  $ cat <<'EOF' >> .hg/hgrc
  > [templates]
  > myjson = ' {dict(rev, node|short)|json}'
  > myjson:docheader = '\{\n'
  > myjson:docfooter = '\n}\n'
  > myjson:separator = ',\n'
  > :docheader = 'should not be selected as a docheader for literal templates\n'
  > EOF
  $ hg log -l2 -Tmyjson
  {
   {"node": "95c24699272e", "rev": 8},
   {"node": "29114dbae42b", "rev": 7}
  }
  $ hg log -l1 -T'{rev}\n'
  8

Template should precede style option

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

Add a commit with empty description, to ensure that the templates
below will omit the description line.

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

Default style is like normal output. Phases style should be the same
as default style, except for extra phase lines.

  $ hg log > log.out
  $ hg log --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

  $ cmp log.out style.out || diff -u log.out style.out
  $ hg log -v -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

  $ 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 -q -T phases > phases.out
  $ cmp log.out phases.out || diff -u log.out phases.out

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

Default style of working-directory revision should also be the same (but
date may change while running tests):

  $ hg log -r 'wdir()' | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' --style default | sed 's|^date:.*|date:|' > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' -v | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' -v --style default | sed 's|^date:.*|date:|' > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' -q > log.out
  $ hg log -r 'wdir()' -q --style default > style.out
  $ cmp log.out style.out || diff -u log.out style.out

  $ hg log -r 'wdir()' --debug | sed 's|^date:.*|date:|' > log.out
  $ hg log -r 'wdir()' --debug --style default \
  > | sed 's|^date:.*|date:|' > 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 log -T phases > phases.out
  $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

Remove commit with empty commit message, so as to not pollute further
tests.

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

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

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

Compact style works:

Check that recursive reference does not fall into RuntimeError (issue4758):

 common mistake:

  $ cat << EOF > issue4758
  > changeset = '{changeset}\n'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'changeset' in template
  [255]

 circular reference:

  $ cat << EOF > issue4758
  > changeset = '{foo}'
  > foo = '{changeset}'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'foo' in template
  [255]

 buildmap() -> gettemplate(), where no thunk was made:

  $ cat << EOF > issue4758
  > changeset = '{files % changeset}\n'
  > EOF
  $ hg log --style ./issue4758
  abort: recursive reference 'changeset' in template
  [255]

 not a recursion if a keyword of the same name exists:

  $ cat << EOF > issue4758
  > changeset = '{tags % rev}'
  > rev = '{rev} {tag}\n'
  > EOF
  $ hg log --style ./issue4758 -r tip
  8 tip

Check that {phase} works correctly on parents:

  $ cat << EOF > parentphase
  > changeset_debug = '{rev} ({phase}):{parents}\n'
  > parent = ' {rev} ({phase})'
  > EOF
  $ hg phase -r 5 --public
  $ hg phase -r 7 --secret --force
  $ hg log --debug -G --style ./parentphase

  o  1 (public): 0 (public) -1 (public)

  o  0 (public): -1 (public) -1 (public)
  

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

  $ echo "changeset = '{c}'" > t
  $ hg log --style ./t

Defining non-standard name works:

  $ cat <<EOF > t
  > changeset = '{c}'
  > c = q
  > EOF
  $ hg log --style ./t

Formatnode filter works:

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

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

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

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', 'w')
  >>> n = datetime.datetime.now() + datetime.timedelta(366 * 7)
  >>> fp.write('%d-%d-%d 00:00' % (n.year, n.month, n.day))
  >>> 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

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'

Test recursive showlist template (issue1989):

  $ cat > style1989 <<EOF

  > file_mod  = 'M|{author|person}\n'
  > manifest = '{rev},{author}\n'

  $ hg -R latesttag log -r tip --style=style1989
  M|test

Test new-style inline templating:

  $ hg log -R latesttag -r tip --template 'modified files: {file_mods % " {file}\n"}\n'
  modified files:  .hgtags
  

  $ hg log -R latesttag -r tip -T '{rev % "a"}\n'

  [255]
  $ hg log -R latesttag -r tip -T '{get(extras, "unknown") % "a"}\n'
  hg: parse error: None is not iterable
  [255]

Test new-style inline templating of non-list/dict type:

  11:2bc6e9006ce2
  $ hg log -R latesttag -r tip -T 'string length: {manifest|count}\n'

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

  $ hg log -R latesttag -r tip -T '{join(manifest, "")}\n'
  11:2bc6e9006ce2
  $ hg log -R latesttag -r tip -T '{join(get(extras, "branch"), "")}\n'

        (symbol 'node'))
      (symbol 'short'))
    (string '\n'))
  89f4071fec70

 (the following examples are invalid, but seem natural in parsing POV)

  $ hg debugtemplate -R latesttag -r0 -v '{foo|bar.baz}\n' 2> /dev/null
  (template
    (|
      (symbol 'foo')
      (.

      (func
        (symbol 'bar')
        None))
    (string '\n'))
  [255]

Test evaluation of dot operator:

  $ hg log -R latesttag -l1 -T '{min(revset("0:9")).node}\n'
  ce3cec86e6c26bd9bdfc590a6b92abc9680f1796
  $ hg log -R latesttag -r0 -T '{extras.branch}\n'

  $ hg log -R latesttag -l1 -T '{author.invalid}\n'
  hg: parse error: keyword 'author' has no member
  [255]
  $ hg log -R latesttag -l1 -T '{min("abc").invalid}\n'
  hg: parse error: 'a' has no member
  [255]

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: [
  [255]
  $ hg log -R latesttag -r 10 -T '{sub("[0-9]", r"\1", rev)}\n'
  hg: parse error: sub got an invalid replacement: \1
  [255]

Test the strip function with chars specified:

  $ hg log -R latesttag --template '{desc}\n'
  at3
  t5
  t4
  t3
  t2
  t1
  merge
  h2e
  h2d

  $ hg log -R latesttag --template '{strip(desc, "te")}\n'
  at3
  5
  4

  2
  1
  merg
  h2
  h2d

Test date format:

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

Test ifcontains function

  $ hg log --template '{rev} {ifcontains(rev, "2 two 0", "is in the string", "is not")}\n'
  2 is in the string
  1 is not
  0 is in the string

  $ hg log -T '{rev} {ifcontains(rev, "2 two{" 0"}", "is in the string", "is not")}\n'

 a list template is evaluated for each item of revset/parents

  $ hg log -T '{rev} p: {revset("p1(%s)", rev) % "{rev}:{node|short}"}\n'
  2 p: 1:bcc7ff960b8e

  0 p: -1:000000000000 -1:000000000000

 therefore, 'revcache' should be recreated for each rev

  $ hg log -T '{rev} {file_adds}\np {revset("p1(%s)", rev) % "{file_adds}"}\n'
  2 aa b
  p 
  1 
  p a

  $ hg log --debug -T '{rev} {file_adds}\np {parents % "{file_adds}"}\n'
  2 aa b
  p 
  1 
  p a
  0 a
  p 

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
  5:13207e5a10d9fd28ec424934298e176197f2c67f,

Templater supports aliases of symbol and func() styles:

  $ hg clone -q a aliases

Aliases should be applied only to command arguments and templates in hgrc.
Otherwise, our stock styles and web templates could be corrupted:

  $ hg log -r0 -T '{rn} {utcdate(date)|isodate}\n'

  $ cat <<EOF > tmpl

  $ hg log -r0 --style ./tmpl
  nothing expanded:

Aliases in formatter:

  $ hg branches -T '{pad(branch, 7)} {rn}\n'
  default 6:d41e714fe50d
  foo     4:bbe44766e73d

Aliases should honor HGPLAIN:

  $ HGPLAIN= hg log -r0 -T 'nothing expanded:{rn}\n'
  nothing expanded:
  $ HGPLAINEXCEPT=templatealias hg log -r0 -T '{rn}\n'
  0:1e4e1b8f71e0

Unparsable alias:

  abort: bad definition of template alias "bad": at 2: not a prefix: end
  [255]
  $ hg log --config templatealias.bad='x(' -T '{bad}'

Set up repository for non-ascii encoding tests:

  $ hg init nonascii

Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
printed graphwidths 3, 5, 7, etc. should all line up in their respective
columns. We don't care about other aspects of the graph rendering here.

  $ hg init graphwidth

The point of graphwidth is to allow wrapping that accounts for the space taken
by the graph.

  $ COLUMNS=10 hg log --graph -T "{fill(desc, termwidth - graphwidth)}"

Something tricky happens when there are elided nodes; the next drawn row of
edges can be more than one column wider, but the graph width only increases by
one column. The remaining columns are added in between the nodes.
