Stringtemplate Unicode Renderer
Posted by sky | Tags: Python
The stringtemplate library is a port of java template engine StringTemplate. The python stringtemplate documentation. The default string rendering of the library doesn't handle unicode string. Below describes how I handle it.
import stringtemplate
class UnicodeStrRenderer(stringtemplate.AttributeRenderer):
def __init__(self):
pass
def str(self, o):
return o.encode('utf8')
dir = "tmp"
tgrp = stringtemplate.StringTemplateGroup('test', dir)
tgrp.registerRenderer(unicode, UnicodeStrRenderer())
There is a bug in StringTemplateGroup getAttributeRenderer.
def getAttributeRenderer(self, attributeClassType):
if not self.attributeRenderers:
if not self.superGroup:
return None # no renderers and no parent? Stop.
# no renderers; consult super group
return self.superGroup.getAttributeRenderer(attributeClassType)
if self.attributeRenderers.has_key(attributeClassType):
renderer = self.attributeRenderers[attributeClassType]
else:
# no renderer registered for this class, check super group
if not self.superGroup: return None # add this line to fix
renderer = self.superGroup.getAttributeRenderer(attributeClassType)
return renderer
