.. include:: ../README.rst
Using ``zope.tal`` requires three steps: choosing an expression engine
(usually :mod:`zope.tales`), creating a generator and parser, and then
interpreting the compiled program::
from io import StringIO
from zope.tal.talgenerator import TALGenerator
from zope.tal.htmltalparser import HTMLTALParser
from zope.tal.talinterpreter import TALInterpreter
compiler = None # Will use a compiler for a dummy language
source_file = '<string>'
source_text = '<html><body><p>Hi</p></body></html>'
gen = TALGenerator(compiler, source_file=source_file)
parser = TALParser(gen)
parser.parseString(source_text)
program, macros = parser.getCode()
output = StringIO()
context = None # Usually will create a zope.tales context
interpreter = TALInterpreter(self.program, macros, context, stream=output)
interpreter()
result = output.getvalue()
These aspects are all brought together in :mod:`zope.pagetemplate`.
