Many of the people subscribed want to get any insight into the DLR languages as they can. But I have noticed that there are some user-type questions that get no responses here. It is easy to join two mailing lists, and if splitting would allow user-questions to get more attention, then that would be a good thing. -Doug > ~Jimmy From m.schaber at 3s-software.com Fri Apr 1 15:54:06 2011 From: m.schaber at 3s-software.com (Markus Schaber) Date: Fri, 1 Apr 2011 15:54:06 +0200 Subject: [IronPython] IronPython use case: CoDeSys Message-ID: Hi, For all those collecting information about usages of IronPython: The "Controller Development System" CoDeSys is the industry leading development tool (IDE and runtime system) for programming PLCs using the standardized IEC 61131-3 language. The current release V3.4 SP3 includes an IronPython 2.6.2 based scripting plugin that allows to automate and control established CoDeSys functionality like importing applications written in the PLCOpenXML standard, compiling and downloading applications to the device, or runtime monitoring of variables, both from within the IDE and from command line. The script writers can also utilize the power of the python standard library which is included, this allows for advanced task like sending monitored variable values via E-Mail.

I'd like to see those changes and fixes in version 2.7, for all those people who cannot yet migrate to .NET 4.0.

That's all I've been doing. In Solution Explorer, right click the project file and select "Properties" to open the properties page. Set the "Interpreter Path" field to the actual path of your ipy.exe or ipyw.exe. E.g., mine is set to "c:/IronPython 2.7/ipy.exe", without quotes. (I don't like using "Program Files..." folders - ACL issues.) Also, it sounds you are still using the "old" tools. (Not that it matters in this case, but if you have haven't switched to the "new" tools yet, I highly recommend it.) http://pytools.codeplex.com/ Caveat: You WILL have to uninstall IronPython 2.7 and re-install it WITHOUT the bundled tools, and THEN install the new tools. They cannot be installed sxs. But I think the effort is well worth it. And there is a really good walkthrough for it. (In the new tools, you also have Tools>Options>Python Tools with several settings tabs for more options.) I just finished converting my IPyScratchPad app (gen-purpose utility UI) to WPF from WinForms and switched to the new tools mid-stream, just for extra fun. But I've had no trouble with it. BTW, did I mention the new tools ARE GREAT!. Thanks, y'all.

For example, writing a C# function that can be used naturally in IronPython as if it were written in Python, IronRuby as if it were written in Ruby, and F# as if it were written in F#, etc. I've encountered some gotchas that I thought I'd share, and looking for any other points of advice in writing cross-language libraries. 1. IronRuby strings aren't really strings, so you need to pass them in as an object, and call .ToString(). public static string expects_string(object val) { return val.ToString(); } 2. F# 2.0 doesn't seem to automatically convert a type to the associated nullable type, so avoid nullable types as parameters. // AVOID: public static double? expects_nullable(double? var1=null) { return var1; } // BETTER: public static double? expects_nullable() { return null; } public static double expects_nullable(double var1) { return var1; } 3. IronPython and IronRuby lists and dictionaries implement IList and IDictionary, so no problem with those. public static IDictionary make_dict(object val) { if (val as IDictionary != null) { return ((IDictionary)val); } else throw new System.ArgumentException("object is not a dictionary"); } public static IList
