Persistent Python Page - Content Type
Persistent Python Scripts
Examples:
>>> from cybertools.pyscript.tests import Root
>>> from cybertools.pyscript.script import PythonPage
>>> from cybertools.pyscript.script import PythonScript
>>> pp = PythonPage()
>>> pp = PythonScript()
>>> pp.__parent__ = Root()
>>> pp.__name__ = 'pp'
>>> request = None
Test that can produce the correct filename
>>> pp._PythonPage__filename()
>>> pp._PythonScript__filename()
u'/pp'
A simple test that checks that any lone-standing triple-quotes are

>>> pp.setSource(u"'''<html>...</html>'''\nreturn printed")
>>> pp(request)
'<html>...</html>\n'
u'<html>...</html>\n'
Make sure that strings with prefixes work.
>>> pp.setSource(ur"ur'''test\r'''" + "\nreturn printed")
>>> pp.setSource(ur"ur'''test\\r'''" + "\nreturn printed")
>>> pp(request)
'test\\r\n'
u'test\\r\n'
Make sure that Windows (\r\n) line ends also work.
>>> pp.setSource(u"if 1 == 1:\r\n\r\n '''<html>...</html>'''\nreturn printed")
>>> pp(request)
'<html>...</html>\n'
u'<html>...</html>\n'
Make sure that unicode strings work as expected.
>>> #pp.setSource(u"u'''\u0442\u0435\u0441\u0442'''")
>>> #pp(request)
u'\u0442\u0435\u0441\u0442\n'
>>> pp.setSource(u"u'''\u0442\u0435\u0441\u0442'''\nreturn printed")
>>> pp(request)
u'\u0442\u0435\u0441\u0442\n'
Make sure that multi-line strings work.
>>> pp.setSource(u"u'''test\ntest\ntest'''\nreturn printed")
>>> pp(request)
'test\n...test\n...test\n'
u'test\n...test\n...test\n'
Here you can see a simple Python command...
>>> pp.setSource(u"print u'<html>...</html>'\nreturn printed")
>>> pp(request)
'<html>...</html>\n'
u'<html>...</html>\n'
... and here a triple quote with some variable replacement.
>>> pp.setSource(u"'''<html>%s</html>''' %x\nreturn printed")
>>> pp(request, x='test')
'<html>test</html>\n'
u'<html>test</html>\n'
Make sure that the context of the page is available.
>>> pp.setSource(u"'''<html>%s</html>''' %context.__name__\nreturn printed")
>>> pp(request)
'<html>root</html>\n'
u'<html>root</html>\n'
Make sure that faulty syntax is interpreted correctly.
