Python Scripts

|
Persistent Python Scripts
|
|
|
|
Examples:
|
|
|
|
>>> from cybertools.pyscript.tests import Root
|
|
>>> from cybertools.pyscript.script import PythonScript
|
|
|
|
>>> pp = PythonScript()
|
|
>>> pp.__parent__ = Root()
|
|
>>> pp.__name__ = 'pp'
|
|
>>> request = None
|
|
|
|
Test that can produce the correct filename
|
|
|
|
>>> pp._PythonScript__filename()
|
|
u'/pp'
|
|
|
|
A simple test that checks that any lone-standing triple-quotes are
|
|
being printed.
|
|
|
|
>>> pp.setSource(u"'''<html>...</html>'''\nreturn printed")
|
|
>>> pp(request)
|
|
u'<html>...</html>\n'
|
|
|
|
Make sure that strings with prefixes work.
|
|
|
|
>>> pp.setSource(ur"ur'''test\\r'''" + "\nreturn printed")
|
|
>>> pp(request)
|
|
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)
|
|
u'<html>...</html>\n'
|
|
|
|
Make sure that unicode strings work as expected.
|
|
|
|
>>> 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)
|
|
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)
|
|
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')
|
|
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)
|
|
u'<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
