In this project we want to change this stateof affairs by providing a <i>tutorial</i> about ML-coding in Isabelle. At its centre we describe the implementation of a simple prototypical Isabelle package (we describea simplified version of the inductive package). We hope by documenting every aspect of this package that in the future you will be able to modify, extend and adapt this package for your own purposes, see how developers code in Isabelle and understand better Isabelle's idiosyncrasies. As a result you will be able to quickly produce code for your own needs and will be able to participate in keeping Isabelle alive in the long run. <p>Specific topics of the tutorial we have not yet covered: <P><ul><li> First Steps<ul> <li>theories, contexts and local theories<li>morphisms<li>name spaces</ul><li>Parsing<ul><li>context-, argument- and attribute parsers<li>parsing and printing translations<li>methods</ul><li>Tactical Reasoning<ul><li>declarations<li>structured proofs</ul><li>Advanced Stuff<ul> <li>user-space type-systems<li>typing algorithms<li>external applications</ul></ul><P>Please help us to expand on this list. <H3>We need You</H3>We need help for accomplishing this tutorial. If you are familiar with the ML-level of Isabelle, please get in contact with us (see addresses below). If you are not familiar, but like to know more about the bits and pieces that makeup the Isabelle code, then let us know what you are interested in or whatproject you like to implement. Above all we like to help future users and developers of Isabelle; we do not want to end up with some "artificial documentation" that is of nobody's help. Also proofreading and feedback would be mostappreciated.<H3>People to contact</H3>The project is managed by<ul><li> <A HREF="http://www.inf.kcl.ac.uk/staff/urbanc/" target="_top">Christian Urban</A> (christian.urban at kcl ac uk)<li> <A HREF="http://www.cl.cam.ac.uk/~lp15/" target="_top">Larry Paulson</A> (lp15 at cam ac uk)<li> <A HREF="http://nicta.com.au/people/norrishm" target="_top">Michael Norrish</A> (Michael.Norrish at nicta com au)</ul>There is also the following mailing list that is subscribed by all developersand open for help, suggestions etc. about this project.<p><A HREF="https://mailmanbroy.informatik.tu-muenchen.de/mailman/listinfo/isabelle-dev">isabelle-dev@mailbroy.informatik.tu-muenchen.de</A><BR><p><H3>Repository</H3>A preliminary <A HREF="http://www4.in.tum.de/~urbanc/cgi-bin/repos.cgi/isabelle-cookbook" target="_top">repository</A>is available and you are very welcome to contribute to it.

That's exactly what I was looking for! (Thomas Genet, ISTIC/IRISA, 2012)</i><p><i>The tutorial really is quite nice. (Jeremy Avigad, CMU, 2011)</i><p><i>By the way, thanks for the Isabelle Cookbook, it's really helpful to start with Isabelle/ML. (Mathieu Giorgino, 2011)</i><p><i>Great! This seems to have a lot of the missing pieces I couldn't find in the tutorial and reference manual. (Kevin Van Horn, 2011)</i><p><i>I've been fighting for hours trying to derive some theorems automatically, until Florian told me I should try using conversions and then I read the Cookbook section and it solved my problem. The example with abs_conv in particular was particularly illuminating. Thanks! (Jasmin Blanchette, TU Munich, 2010)</i><p><i> The cook book seems really helpful, if not even exactly what I need. (Nils Jähnig, FU Berlin, 2010)</i><p><i>The Programming Tutorial has helped me tremendously to get familiar withIsabelle, which I used in my bachelor thesis about the type-inference algorithm in Isabelle. (Dmitriy Traytel, TU Munich, 2010)</i><p><i>I've already pointed a couple of PhD students at the programming tutorial, andthey've already found it to be a great place to start with Isabelleprogramming. (Lucas Dixon, University of Edinburgh, 2009)</i> <p><i>The Isabelle Programming Tutorial is great! I finally learned how to add new keywords and how to parse outer syntax! (Amine Chaieb, University of Cambridge)</i><p><i>I felt the programming tutorial was very clear and comprehensible. I'mtoying with actually getting back to Isabelle again. Thanks to everyone involved in the documentation project. I really think itis worthwhile. (Tom Ridge, University of Cambridge, 2009)</i><p><i>I learned from the tutorial how to deal with fresh variables and also which function to usefor applying substitutions that are generated by unification.(Lukas Bulwahn, TU Munich, 2009)</i><p><i> What a great resource! I wish I'd had this when I wrote my firstparser in December 2008.
