.. 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 = '' source_text = '

' 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`.
