Announcement: Project to get some CPython C extensions running under IronPython
The great thing about CPython is that it comes with the batteries included. The problem with IronPython is that some of these batteries just don't fit - in particular, most of the the C extensions don't work. We'd like to help fix at least some of this problem, to help people who use IronPython to use their CPython scripts without having to port everything over to .NET. Solving the general problem - plugging an arbitrary C extension into IronPython - is a huge project, and we're not even sure we could work out *how much work it is* without a lot of investigation. What we intend to do is to solve a specific problem, to integrate just one extension, and to use that project as a testbed to examine the possibilities for getting other extensions working - and perhaps, in the long term, solving the general problem. We think that any solution like this will be valuable not just to us, but to the Python community as a whole. And so, we want to make it Open Source. Right now, we'd really like to hear from people about the following: * Who wants to get involved? We're really keen on working with other people on this. * Which module should we go for? NumPy looks like a good start, as it gives us a start on getting SciPy working. But perhaps there are better choices. * Should this be a new project, or should we be talking to other people about getting it into other projects? * Which license? If we're to work on it with a view to building it into Resolver One, then it will need to be commercial-software-friendly. Apart from that - we have no view. * What is the best architecture? We're thinking of this as being a bit of C# managed code to interface with the C extension, and a thin Python wrapper on top. The module's existing C extension and Python code would "sandwich" this layer. Let us know if this is a silly idea :-) * Is there anything else we should be thinking about to get this started? Any thoughts much appreciated! Regards, Giles -- Giles Thomas MD & CTO, Resolver Systems Ltd.

ANNOUNCE: Resolver One public Beta now live
We're proud to announce that today Resolver One, our flagship application, entered its public Beta phase. It can be downloaded from <http://www.resolversystems.com/download/> (free registration required), and we would very much welcome feedback from the Python community. Resolver One is a Rapid Application Development tool for analysing and presenting business data using a familiar spreadsheet interface - or, to put it another way, it is a mash-up of a spreadsheet and an IDE. As you enter formulae on the grid, it writes the equivalent IronPython code for you. As you add your own IronPython code, the grid is updated. This allows you to build applications that are much more complex but better-structured than a traditional spreadsheet, much more quickly than you could if you were using a regular programming language. You can then export the code and re-use it elsewhere in your own programs. It's primarily targetted at heavy users of number-crunching software, such as financial firms and the biotech industry, but we use it internally for all kinds of scripts, so we think any Python programmer will be able to do fun stuff with it. If you're interested in taking a look, please do download it or drop us a line! Best regards, Giles -- Giles Thomas MD & CTO, Resolver Systems Ltd.

ANN: Resolver One 1.0.1
Hi! We're delighted to announce version 1.0.1 of Resolver One, a Windows spreadsheet/IDE mashup that can be programmed in IronPython. As you enter formulae on the grid, it writes the equivalent IronPython program for you. As you add your own code, the grid is updated. This allows you to build applications that are much more complex but better-structured than a traditional spreadsheet, much more quickly than you could if you were using a regular programming language. You can then export the code and re-use it elsewhere in your own programs. It's primarily targetted at heavy users of number-crunching software, such as financial firms and the biotech industry, but we use it internally for all kinds of tasks, so we think any Python developer will be able to do fun stuff with it :-) This is primarily a performance enhancement and bugfix release, but has a couple of features correcting the more egregious missing features in version 1.0. We've put up a full change list, but the highlights are: * Many memory usage and performance fixes, in particular while importing Excel-format spreadsheets. * Updated to IronPython 1.1.1 (fixes socket bugs) * Added UI to set the background color. * Fixed defect 367 - Looking up cells by header row/col is slow * Fixed defect 370 - Cut and Copy part of the text in a cell is not handled correctly If you want to download the non-commercial version of the software, or to buy the commercial version, you can download it from our website (free registration required): <http://www.resolversystems.com/get-it/> Regards, Giles Giles Thomas MD & CTO, Resolver Systems Ltd.

Resolver One 1.4 beta - with IronPython 2.0 and numpy
Hi all, Version 1.4 of Resolver One, our Pythonic spreadsheet, uses the Ironclad project to provide (alpha-level) support for numpy in a IronPython application. You can put numpy matrices in spreadsheet cells and manipulate them like any other data - there's a 4-minute screencast here: <http://www.resolversystems.com/screencasts/numpy/> We're releasing the beta tomorrow: this has a few performance problems but is otherwise functionally complete.

ANN: Resolver One 1.3 released
We are proud to announce the release of Resolver One, version 1.3. Resolver One is a spreadsheet that allows you to write Python directly in cells, and converts the spreadsheets you create into Python programs. It's based on IronPython, and runs on Windows. For version 1.3, we've made two big changes: * Our Web server, which (as you would expect) allows you to expose your spreadsheets to other people as web applications, is now included - it was previously a commercial-only product. * We've added column- and row-level formulae. With these, you can specify one formula which is then used to fill in a whole column or row, reducing duplication and starting to bring some of the benefits of loops to the spreadsheet world. We've done a screencast outlining both of these: Michael Foord also did a great screencast describing how you can use Python-syntax formulae with column-level formulae to do interesting stuff: <http://www.resolversystems.com/screencasts/column-formulae/> Resolver One is free for non-commercial use, so if you would like to take a look, you can download it from our website: Best regards, Giles -- Giles Thomas MD & CTO, Resolver Systems Ltd.

There's a one-minute screencast about it here: <http://www.resolversystems.com/screencasts/resolver-one-in-one> For version 1.1 , we’ve made quite a lot of changes, hopefully making the program more responsive and pleasant to use - as well as adding cool new features. Some of the highlights: * Significant improvements to performance and memory usage. * Cutting and pasting is now more "spreadsheet-like". * User-defined formatter functions on a per-cell basis. * Ability to "unpack" Python iterables into ranges of cells. * Auto-indent in the code editor. * Better coverage of standard spreadsheet functions. * Comments in cells. * For the financial edition, we've added Thomson Dataworks Enterprise connectivity and a number of great enhancements to Bloomberg access. We’ve put together a three-minute screencast outlining all these changes: <http://www.resolversystems.com/screencasts/release-1.1/> It's free for non-commercial use (and quite cheap for commercial use :-), so if you would like to take a look, you can download it from our website (free registration required): <http://www.resolversystems.com/get-it/> Best regards, Giles -- Giles Thomas MD & CTO, Resolver Systems Ltd.

It's really IronPython-specific, which is both a blessing - there's a suprising amount of really good .NET classes out there and it's great to be able to script them using Python from a grid-based environment - and a curse, because we lose the cross-platform capabilities and the C extensions like numpy. We're working on sorting out the latter with a project called Ironclad (<http://www.resolversystems.com/documentation/index.php/IronClad>) which aims to get C extensions working in IronPython. For the cross-platform stuff, in the longer term we hope to be Mono-compatible and so be able to support Linux and the Mac. All the best, Giles -- Giles Thomas MD & CTO, Resolver Systems Ltd.

Re: ANN: Resolver One 1.2 released
2008/8/19 km <[EMAIL PROTECTED]> Hi, sounds great - but disappointing to find it only available on window$. Is there any Linux release in near future ??? KM Not in the near future, unfortunately - but we're looking at getting it running under Mono in the medium term. The big problem is that we'll have to change (or even recode) our grid component.
