Python Page
|
||||
===========
|
||||
============
|
||||
Python Pages
|
||||
============
|
||||
|
||||
Python Page provides the user with a content object that interprets
|
||||
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.
|
||||
Persistent Python Page - Content Type
|
||||
|
||||
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
|
||||
code example::
|
||||
>>> pp = PythonPage()
|
||||
>>> pp.__parent__ = Root()
|
||||
>>> pp.__name__ = 'pp'
|
||||
>>> request = None
|
||||
|
||||
'''
|
||||
<html>
|
||||
<body>
|
||||
<ul>
|
||||
'''
|
||||
Test that can produce the correct filename
|
||||
|
||||
import time
|
||||
print time.asctime()
|
||||
>>> pp._PythonPage__filename()
|
||||
u'/pp'
|
||||
|
||||
'''
|
||||
</ul>
|
||||
</body>
|
||||
</html>
|
||||
'''
|
||||
A simple test that checks that any lone-standing triple-quotes are
|
||||
being printed.
|
||||
|
||||
>>> 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
