Re: [Paste] [Tempita] Minor Bug

[Ian Bicking]

Yeah, unfortunately this is just a limitation of how the Tempita is written, it would be hard to fix.  An unfortunately hard-to-read workaround would be ' \x7c\x7c '.join(mylist)

Hi,
sorry for posting this bug description here, but the trac instance from tempita docs is down (nginx error) .
It's impossible to write the following expression with Tempita 0.5  :

 {{" || ".join(mylist)}}.

The '|' caracters causes the parser to crash with the following message :

Traceback (most recent call last):
  File "/local/src/Tempita-0.5.1/tempita/__init__.py", line 1183, in <module>
    fill_command()

    result = template.substitute(vars)
  File "/local/src/Tempita-0.5.1/tempita/__init__.py", line 173, in substitute
    result, defs, inherit = self._interpret(ns)
  File "/local/src/Tempita-0.5.1/tempita/__init__.py", line 184, in _interpret
    self._interpret_codes(self._parsed, ns, out=parts, defs=defs)

    base = self._eval(parts[0], ns, pos)
  File "/local/src/Tempita-0.5.1/tempita/__init__.py", line 297, in _eval
    'invalid syntax in expression: %s' % code)
SyntaxError: invalid syntax in expression: '

Writing a function doing this join in a py block , and then call that method at the same place is ok . I guess it has some link with the filter expression, so i've tried to escape the | using a backslash but this does note work.
