| * Implement module export so we can export a subset of items defined in theGravatar qunyanm2016-01-29
| | | | | | | | module.
| * Revert Makefile to its prior settingsGravatar Richard L. Ford2016-01-29
| | | | | | | | | | The prior change did not work for people who had their setup using the previous values.
| * Add Dafny reference manualGravatar Richard L. Ford2016-01-27
| | | | | | | | | | | | | | | | | | This version is still a draft, but is mostly complete and about half reviewed. The manual is written using Madoko. The sources are in the Docs/DafnyRef directory. The processed sources are available in the Docs/DafnyRef/out directory in the form of a single HTML page or as a PDF.
| * Fix build and test failures, cleanup grammar.Gravatar Richard L. Ford2016-01-27
| | | | | | | | | | | | | | | | | | | | 1. A build failure caused by a method call before a contract was fixed. 2. An absolute path in an ".expect" file was changed to relative. 3. I eliminated the TopDecls and DeclModifiers non-terminals. They were giving a warning from Coco/R about being deletable. Instead I used repetition of the TopDecl or DeclModifier non-terminals where they had been used. I think this is also cleaner to talk about.
| * Add ExternNegative2.dfy.expect.Gravatar Richard L. Ford2016-01-27
| | | | | | | | | | | | In the prior commit the ExternNegative2.dfy.expect file was accidentally not included. It is needed in order for that test to pass.
| * Implement 'extern' declaration modifier.Gravatar Richard L. Ford2016-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'extern' declaration modifier provides a more convenient way of interfacing Dafny code with C# source files and .Net DLLs. We support an 'extern' keyword on a module, class, function method, or method (cannot extern ghost). We check the CompileNames of all modules to make sure there are no duplicate names. Every Dafny-generated C# class is marked partial, so it can potentially be extended. The extern keyword could be accompanied by an optional string naming the corresponding C# method/class to connect to. If not given the name of the method/class is used. An 'extern' keyword implies an {:axiom} attribute for functions and methods, so their ensures clauses are assumed to be true without proof. In addition to the .dfy files, the user may supply C# files (.cs) and dynamic linked libraries (.dll) on command line. These will be passed onto the C# compiler, the .cs files as sources, and the .dll files as references. As part of this change the grammar was refactored some. New productions are - TopDecls - a list of top-level declarations. - TopDecl - a single top-level declaration - DeclModifiers - a list of declaration modifiers which are either 'abstract', 'ghost', 'static', 'protected', or 'extern'. They can be in any order and we diagnose duplicates. In addition, since they are not all allowed in all contexts, we check and give diagnostics if an DeclModifier appears where it is not allowed.

| | | | | | | | | | | | | | | | | | | | | | | | - cache scan results so it can be shared between different instances of DafnyTokenTagger - Instead of rescanning the whole text buffer upon a text change, only rescan the text span that the text change is in. - set the timer to half a second to match the comment at the beginnig of the file. The event change are only passed along to Dafny when the user stop typing for half a second. - Change framework dependence so the project can work with version 4.5 and higher.
