Here's a class wrapping your functionality:
import re
class Template(object):
'''uses double brackets e.g [[ob.attr]] as delims to get
around curly bracket ({}) collisions when generating code
'''
_pattern = re.compile(r"\[\[|]]|\{|\}")
_lookup = {
"[[": "{",
"]]": "}",
"{": "{{",
"}": "}}",
}
def __init__(self, txt):
self.txt = txt
self.type = type
def _substitute(self, m):
return self._lookup[m.group()]
def render(self, *args, **kwds):
return self._pattern.sub(
self._substitute, self.txt).format(*args, **kwds)
def test_Template():
class P: pass
p = P()
p.name = 'peter'
txt = 'hello there [[o.name]]'
t = Template(txt)
assert t.render(o=p) == 'hello there peter'
