Thanks for the feedback. In CPython, there are actually two implementations of pickle: one written in Python (pickle) and one written in C (cPickle). Only the Python version of pickle is available in beta 9, but we're hoping to include an implementation of cPickle, which should be quite a bit faster, in a future release of IronPython.
What is the nature of the dict that you're trying to save? How many elements does it have, and what data types are those elements? Maybe there's something we can do to improve pickle's performance for you. --Bruce -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of JoeSox Sent: Wednesday, July 19, 2006 10:06 PM To: Discussion of IronPython Subject: Re: [IronPython] Dict convertion question Perfect Bruce thanks for the suggestion. Thanks exactly what I was looking for. However, it took around six minutes to create a file using pickle, as opposed to one second when I used File.WriteAllText. I understand pickle may be compressing but the space savings is not a significant enough benefit. Here's my code examples below and the file sizes(both used the same Dict): Dict myDict = new Dict(); engine.ExecuteToConsole("fw={}"); engine.ExecuteToConsole("fw=c.fw_edges");//c.fw_edges is the large dictionary myDict = (Dict)engine.Globals["fw"]; File.WriteAllText(Application.StartupPath + "\\mydict.txt", myDict.ToCodeString()); (This results in a file size of 1,540,096 bytes which was created in about a second.) ====== engine.Globals["myfile"] = Application.StartupPath + "\\fw_edges.txt"; engine.Import("pickle"); engine.ExecuteToConsole("output =open(myfile, 'wb')"); engine.ExecuteToConsole("pickle.dump(c.fw_edges,output, protocol=2)"); engine.ExecuteToConsole("output.close()"); (This results in a file size of 1,052,672 bytes which was created in about six minutes or more.) I would like the speed of File.WriteAllText, the compression is not really an issue for me. -- Later, Joe On 7/19/06, Bruce Christensen <[EMAIL PROTECTED]> wrote: > Since we just added support for this, please let us know if you run into > any problems. > --Bruce _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
