Hi, I just noticed that my Graphane library, written in Python, doesn't work in Blue. It stops the compilation with the error message that there is a syntax error in "yield progress[0]". I did some searching and found that yield with an expression is available in Python since version 2.5. So I wonder what version of the Python language is supported in Blue. I know that Jython is used, but on the Jython website I didn't find what version of the Python language is supported. Kind regards, -- Mark _________________________________________ When you get lemons, you make lemonade. When you get hardware, you make software. |

Hi Mark! The version of Jython that is packaged with blue is a bit old; the latest Jython is 2.5 and I think it supports most of the Python 2.5 features. I think yield and generators were available earlier than 2.5 using the future package. Hmm... looks like they were available in 2.2, but you have to use: from __future__ import generators (read from this article: http://www.ibm.com/developerworks/library/l-pycon.html ) I'd try adding that. I think importing from __future__ is safe to use in versions after 2.2 as I think it just doesn't import anything, but maybe try and verify. I am planning on updating to 2.5 as part of blue2, but have to rework how Jython is used to accomodate Netbeans RCP conventions. I am hoping to get back to blue2 work on Wednesday (I'm pretty much writing this chapter text all weekend and am very much looking forward to being done with it! :P). Let me know if that works! steven On Sat, Aug 22, 2009 at 10:00 AM, Mark Van Peteghem<Mar...@te...> wrote: > Hi, > > I just noticed that my Graphane library, written in Python, doesn't work > in Blue.

Hi Steven, Thanks, that worked perfectly! Adding the line works in both Python 2.6 and Jython in Blue. I'm looking forward to blue2; if I find time, I would like to test it as well.

Hi Mark, I'm very glad this is now all working! Thanks for your offer and I will be looking forward to hearing your feedback when blue2 is in beta! steve On Sat, Aug 22, 2009 at 4:20 PM, Mark Van Peteghem<Mar...@te...> wrote: > Hi Steven, > > Thanks, that worked perfectly!
