This is a bit ugly but it may work for you:
#!/usr/bin/env python
import Cheetah.Compiler
import Cheetah.Template
class MyAutoMethodCompiler(Cheetah.Compiler.AutoMethodCompiler):
def addPlaceholder(self, expr, filterArgs, rawPlaceholder,
cacheTokenParts, lineCol,
silentMode=False):
if rawPlaceholder == u'$LINE':
self.addFilteredChunk(repr(unicode(lineCol[0])),
filterArgs,
rawPlaceholder,
lineCol=lineCol)
else:
super(MyAutoMethodCompiler, self).addPlaceholder(
expr, filterArgs, rawPlaceholder,
cacheTokenParts, lineCol,
silentMode=silentMode)
class MyAutoClassCompiler(Cheetah.Compiler.AutoClassCompiler):
methodCompilerClass = MyAutoMethodCompiler
class MyCompiler(Cheetah.Compiler.Compiler):
classCompilerClass = MyAutoClassCompiler
tclass = Cheetah.Template.Template.compile('''\
This is line $LINE
Hello, $name!
And this is line $LINE''', compilerClass=MyCompiler)
print tclass(searchList=[{"name": "Nate"}])
