Python Page ============
=========== Python Pages
============
Python Page provides the user with a content object that interprets Persistent Python Page - Content Type
Python in content space. To save typing and useless messing with
output, any free-standing string and print statement are considered
for output; see the example below.
Examples:
Example >>> from cybertools.pyscript.tests import Root
------- >>> from cybertools.pyscript.script import PythonPage
Create a new content type called "Python Page" and enter the following >>> pp = PythonPage()
code example:: >>> pp.__parent__ = Root()
>>> pp.__name__ = 'pp'
>>> request = None
''' Test that can produce the correct filename
<html>
<body>
<ul>
'''
import time >>> pp._PythonPage__filename()
print time.asctime() u'/pp'
''' A simple test that checks that any lone-standing triple-quotes are
</ul> being printed.
</body>
</html> >>> pp.setSource(u"'''<html>...</html>'''\nreturn printed")
''' >>> pp(request)
'<html>...</html>\n'
Make sure that strings with prefixes work.
>>> pp.setSource(ur"ur'''test\r'''" + "\nreturn printed")
>>> pp(request)
'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'
Make sure that unicode strings work as expected.
>>> #pp.setSource(u"u'''\u0442\u0435\u0441\u0442'''")
>>> #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'
Here you can see a simple Python command...
>>> pp.setSource(u"print u'<html>...</html>'\nreturn printed")
>>> pp(request)
'<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'
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'
Make sure that faulty syntax is interpreted correctly.
Note: We cannot just print the error directly, since there is a
'bug' in the Linux version of Python that does not display the filename
of the source correctly. So we construct an information string by hand.
>>> def print_err(err):
... print ('%(msg)s, %(filename)s, line %(lineno)i, offset %(offset)i'
... % err.__dict__)
...
>>> try:
... pp.setSource(u"'''<html>...</html>") #'''"
... except SyntaxError, err:
... print_err(err)
EOF while scanning triple-quoted string, /pp, line 4, offset 47
>>> try:
... pp.setSource(u"prin 'hello'")
... except SyntaxError, err:
... print_err(err)
invalid syntax, /pp, line 3, offset 16
