PyDev for Eclipse / Discussion / Please post to StackOverflow with PyDev tag: Syntax disagreement between IDLE and pydev?

James Garrison - 2009-03-30

IDLE (3.1a1) accepts

    a,*b = re.split(str,pattern)

and does the right thing ('a' gets the first result and 'b' gets
the rest).

pydev configured to use the exact same Python 3.1a1 runtime flags this
as a syntax error:

Encountered "*" at line 32, column 23. Was expecting one of: <NEWLINE> ...     ";" ...     "=" ...
"+=" ...     "-=" ...     "*=" ...     "/=" ...     "//=" ...     "%=" ...     "&=" ...     "|=" ...     "^=" ...
"<<=" ...     ">>=" ...     "**=" ...     "lambda" ...     "not" ...    "+" ...     "-" ...     "~" ...     "(" ...
"[" ...     "{" ...     "False" ...     "True" ...     "None" ... <NAME> ...     <HEXNUMBER> ...
<OCTNUMBER> ...     <DECNUMBER> ...     <FLOAT> ...     <COMPLEX> ...     "\'" ...     "\"" ...
"\'\'\'" ...     "\"\"\"" ...     "\'" ...     "\"" ...     "\'\'\'" ...     "\"\"\"" ...

HOWEVER, I can execute the code without problems.

Should I file a bug?

  No, this has already been fixed for 1.4.5 (provided you set your project as python 3.0). You can get the nightly and check it (as that should be the released version: http://pydev.blogspot.com/2009/03/new-pydev-release-soon-call-for-testers.html )

  Wow! Thanks for the quick response.
  
  I installed the nightly and it now works.

  This is back after installing the pydev-extensions version (also at 1.4.5.2720).
  
  Looks like some fixes didn't make it into the extensions version build?

    It seems to work for me... are you sure that the project you're editing is marked with a Python 3.0 grammar?

  The project grammar is set to Python 3.0
  
  Versions:
  
  Python 3.1a1
  pydev 1.4.5.2720
  pydev-extensions 1.4.5.2720
  
  This was resolved until I installed pydev-extensions. See also my other thread "pydev extensions - spurious syntax errors"

    Are you sure it's the same error?

  It's on the same line but you're right. The error is now "undefined variable" on "b".
  
  In any event, the code hasn't changed and the error started showing up after installing pydev-extensions.

    You're totally right. That's a bug when treating the StarExp. It was creating a name in the Load context when it should be a Store context (which the Pydev Code Analysis made visible).
    
    I've just fixed that -- it's available for svn 2722 (so, please wait for a build with at least that number and check it again with the extensions).
    
    Cheers,

  The new error still occurred after updating to 2721, but went away after I removed pydev-extensions
