templater: define interface for objects requiring unwraphybrid()
Prepares for introducing another hybrid-like data type. show() takes context
as an argument so a wrapper class may render its items by pre-configured
template:
def show(self, context, mapping):
return (context.expand(self._tmpl, mapping + lm) for lm in self._mappings)
$ hg init
$ touch unknown
$ touch a
$ hg add a
$ hg ci -m "1"
$ touch b
$ hg add b
$ hg ci -m "2"
Should show unknown
$ hg status
? unknown
$ hg revert -r 0 --all
removing b
Should show unknown and b removed
$ hg status
R b
? unknown
Should show a and unknown
$ ls
a
unknown
