 # tokenizer is an iterator that returns (type, value, pos) tuples
 # elements is a mapping of types to binding strength, primary, prefix, infix
 # and suffix actions
 # an action is a tree node name, a tree label, and an optional match
 # __call__(program) parses program into a labeled tree

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

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

 Check that recursive reference does not fall into RuntimeError (issue4758):
 
  common mistake:
 
   $ hg log -T '{changeset}\n'
   abort: recursive reference 'changeset' in template
   [255]
 
  circular reference:
 
   $ cat << EOF > issue4758

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

  buildmap() -> gettemplate(), where no thunk was made:
 
   $ hg log -T '{files % changeset}\n'
   abort: recursive reference 'changeset' in template
   [255]
 
  not a recursion if a keyword of the same name exists:

   > rev = '{rev} {tag}\n'

   $ hg log --style ./issue4758 -r tip

 Check that {phase} works correctly on parents:
 
   $ cat << EOF > parentphase

   > parent = ' {rev} ({phase})'

 Missing non-standard names give no error (backward compatibility):
 
   $ echo "changeset = '{c}'" > t
   $ hg log --style ./t
 
 Defining non-standard name works:

 Test exception in quoted template. single backslash before quotation mark is
 stripped before parsing:

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

 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'
   0:1e4e1b8f71e0 1970-01-12 13:46 +0000

   $ cat <<EOF > tmpl

   > EOF
   $ hg log -r0 --style ./tmpl

   $ 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
