Hello,
hi,
We have a tool that runs scripts created by users.
Scripts are run using eval in some namespace with entities in it such
that users can use a convenient syntax.
Following illustrates this;
def function(i):
print i
scriptglobals = {}
scriptglobals['okko'] = function
script_created_by_user = \
'''
i = 5
okko(i)
'''
eval(compile(script_created_by_user, 'file name', 'exec'),
scriptglobals)
Now we want to lint the user created script.
Running lint with the script obviously fails because the namespace is
missing.
Any ideas how we can pull this off?
I don't know if there is a "classical" way to do it;
but maybe you could overwrite lint.Pylinter.get_astng to return
logilab.astng.builder.ASTNGBuilder.string_build(script_created_by_user)
But that's only half of the job; you will need to use the --init-hook
option to activate the scriptglobals
hope, that helps ;)
Another way could be to slightly rework the user script before passing
it to pylint.
Temporarily adding
from foo import okko
or
def func(*args, **kwargs) :pass
okko = func
at the begining of the file.
There's also an option with pylint to delclare some names as global:
additional-builtins. Adding it to your .pylintrc file is your best bet I
guess.
