python string formatting problems in shelf popup menu commands...

[Brian Eyre]

Hi,

I was getting intermittent syntax errors from code entered into the popup menu of a shelf button, and have narrowed it down to an issue with using '%' in string formatting. Example:

text = 'working'
print 'why is this command not %s'%text

I'm wondering if this is a known issue, or if anyone has a solution?

Cheers!

Brian.

Can see a reason  for that to fail.  Does it just say syntax error?

Just playing with it here (Win, Maya 2012/x64) it comes up with a TypeError: not enough arguments for format string. I've not really used much % string formatting so I'm at a mild loss, but the same code works fine in say, IDLE, so I've a half guess it's how the code block is being passed through to the python interpreter 

Hm, in fact, I'll bet my hat on that - trying this:

print "This really should work, %s"%("right")

Gives me a *KeyError*. Traceback as follows:

#   File "<string>", line 2, in pythonFormat

# KeyError: u"'right'" //

# Error: invalid syntax

#  File "<maya console>", line 2

#  

#    ^

# SyntaxError: invalid syntax #

So whatever is mangling the text in the UI editor to get it into a python interpreter is doing something a tad odd to the string. Short answer appears to be not to use % based formatting, alas.

Aaand of course, couldn't resist playing instead of cooking dinner for myself. Trying this:

print r"what does %s do?"

and I get:

what does {'1': u'False'} do?

Bah.

Thanks folks,

Yeah, it seems to be an issue purely with the shelf popup menu text entry field.  The code works fine in in the single and double-click fields for the same button, and in the script editor.  Weird.

I guess I'll just have to refrain  from using that type of formatting..

Yea just sounds like you are getting unexpected types which you are then applying to the string formatting.

That way it works 

print "what does {0} do?".format('some thing')
