Re: SHPAML v0.1 -- HAML-like language for Python
Just to follow up on the announcement below, SHPAML is a mini language that can help you build web pages more quickly. It runs under Python versions 2.4, 2.5, 2.6, and 3.1. Since the original announcement, I have written a tutorial that allows you try out your own SHPAML examples online: http://shpaml.webfactional.com/tutorial/1 I have also fixed some minor bugs, removed some unneeded features, and cleaned up the download process. As this is a new project, feedback is especially welcome. You can follow this link to find the mailing list: http://shpaml.webfactional.com/discuss Cheers, Steve Howell On Dec 11, 5:10 am, Steve Howell showel...@yahoo.com wrote: SHPAML is a HAML-like language for Python. If you are not familiar with HAML, it is a markup language implemented in Ruby that allows you to create web pages with an indentation-based syntax. SHPAML is not an exact port of HAML, but it shares the same big goal of slimming your markup, and it is written in Python! It is a simple, lightweight preprocessor and intended to be used in many authoring schemes, whether you are producing HTML directly or integrating with a templating system. More details can be found here: http://shpaml.webfactional.com/ It is an early version, but it has been well tested in practice already and is feature-complete for its fairly minimal goals as of now. The site has a link to a mailing list (Google Groups) for further discussion, if this interests you!

Is it possible to get the erroneous variable when getting a NameError exception?
Hi.
I'm trying to evaluate a string and getting a NameError
(it is expected, since the variable my_number wasn't provided in the
locals dictionary).
--snip start--
eval(my_number 10, {__builtins__:None}, {})
Traceback (most recent call last):
File stdin, line 1, in ?
File string, line 0, in ?
NameError: name 'my_number' is not defined
--snip end--
My question is: how can i know which variable name / symbol causes the
NameError exception?
In my example, this symbol is my_number.
Using that information, I will be able to print a nice error message to
the user.
Thanks

Don't waste your time re-inventing the wheel. But if you do insist on
reinventing the wheel, here are some tools to help you:
try:
my_number
except NameError, e:
print str(e)
print type(e)

Recover the exception, and examine the tuple of args or the message string.
try:
... eval(my_number 10, {__builtins__:None}, {})
... except NameError,e:
... print e.args
... print e.message
...

OK. Try this: Executing your code attempts to lookup variables in a
local dictionary. You can rig up a local dictionary of your own
choosing -- in this case, I have it print the name of any variable that
is being looked up before actually doing the lookup.But at that
point, you have what you want, that is, the name as a string -- you can
do with it as you will -- record it, or print your nice error, or ...
You probably want to change my def of __getitem__ to attempt the lookup
first -- if that succeeds, return the value -- if it fails, then handle
the error.
Good luck,

A deque has O(1) behaviour for adding or removing elements from the front or back of the deque. It has O(n) behaviour for lookups. A list has O(n) behaviour for adding/removing, roughly. It has O(1) behaviour for lookups. Removing from the front requires copying all the higher elements down, for example. Adding to the end _may_ cost a copy-the-whole-list if memory needs reallocating. But your lists/deques are VERY small. A deque is a more complicated structure (probably a linked list - I haven't checked). Its basic operation is more expensive and for your test cases probably overwhlems things. You need to use bigger test cases before the deque wins over the list, and of course a deque is only better than a list of your program has behaviour that is expensive for a list.

I think there's a more fundamental question here. You're apparently
looking to build your own error message instead of using the one already
generated. But as you point out, you might end up parsing the existing
error message in order to do that, and that's fragile coding. My take
is that if you're using eval in your code, your user is clearly a
programmer. So why are you not letting that programmer see the real
error message, instead of trying to pretty it up? You can add to the
message, but shouldn't need to hide the original one.
To put it the other way around, if your user can't understand the python
error messages, you should probably not be using unrestricted eval on
something that user supplies. Lots more errors than NameError, and many
of them are more subtle and dangerous.

Hmmm... that wasn't as helpful as I had hoped. Oh well.
Going back to your earlier post, I can see a couple of problems.
Firstly, your __getitem__ method always returns None. You need to return
the result.
Secondly, this works for me:
import logging
class ExtraInfo(object):
def __getitem__(self, name):
if name == 'host':
result = 'foo'
return result
def __iter__(self):
keys = ['host',]
keys.extend(self.__dict__.keys())
return iter(keys) # better than keys.__iter__
def setup(filename='/tmp/foo.log'):
log = logging.LoggerAdapter(logging.getLogger('foo'), ExtraInfo())
logging.basicConfig(
level=logging.DEBUG,
format=Date-Time: %(asctime)s
Host: %(host)s
%(levelname)s:
%(message)s,
datefmt=%Y-%m-%dT%H:%M:%S%z,
filename=filename,
filemode='w')
return log
log = setup()
log.error('testing ...')
log.debug('something happened')
log.critical(it's the end of the world as we know it!)
Hope this helps.

Re: Is it possible to get the erroneous variable when getting a NameError exception?

I think there's a more fundamental question here. You're apparently
looking to build your own error message instead of using the one already
generated. But as you point out, you might end up parsing the existing
error message in order to do that, and that's fragile coding. My take is
that if you're using eval in your code, your user is clearly a programmer.
So why are you not letting that programmer see the real error message,
instead of trying to pretty it up? You can add to the message, but
shouldn't need to hide the original one.
To put it the other way around, if your user can't understand the python
error messages, you should probably not be using unrestricted eval on
something that user supplies. Lots more errors than NameError, and many of
them are more subtle and dangerous.
Hm, is this true, though? Is there anything subtle or dangerous possible
here? He's using eval-- so no statements, its only an expression. He's
passing in a 'globals' which has __builtins__ set to None, so this
environment has access to -- basically nothing. Then the locals dictionary
is empty as well, though I assume he'll fill it with things like my_number.
Its sort of an interesting use for 'eval' that I hadn't ever considered
before, really: ISTM that there's only three possible results.. a NameError,
a SyntaxError, or a safely evaluated expression based on certain pre-defined
objects. Okay, maybe one or two other simple exceptions if one tries to do
strange things with dictionaries/etc in the expression. You can't even make
it blow up to trigger a MemoryError, with some insane list comprehension
because you don't even have access to range(). Unless he's passing an
arbitrarily long string into the expression.
I'm normally against eval -- but maybe I'm blind in not seeing the possible
exploit or subtlety here in this eval-with-zero-access.

menu and file
List, I want to read a file that has a list of data into a menu. User can pick up a line of data and execute it. For example, file has data like following 1 23 0x4530 2 42 0x8790 3 75 0x7684 . User can select line # and then execute hex data in that line. Any sample codes will be appreciated. Thanks! --henry -- http://mail.python.org/mailman/listinfo/python-list
