ChangeLog Separated compiler up into two main components as follows: The Whiley Compiler (wyc). This provides a base compiler which is responsible for parsing whiley programs, as well as type checking and constraint checking them. This outputs whiley bytecode (wyil) which can then either be executed directly, or compiled to some target platform (e.g. . . . → Read More: Whiley v0.3.5 released!
Well, after a fairly long haul, the latest version of Whiley is released. This remains something of a stop-gap for the moment, as there is still quite a lot to do!
ChangeLog Relicensed the tool to use the “New BSD License”. The reason for this is to permit wider distribution of the language. Integrated . . . → Read More: Whiley v0.3.4 Released!
This latest update of Whiley is a somewhat minor increment over the previous. Aside from a number of bug fixes the main improvement is the inclusion of first-class functions (aka function pointers). Constraint checking remains disabled, as it still needs a considerable amount of work (which I’m working on 🙂
Function pointers can be . . . → Read More: Whiley v0.3.3 Released!
Well, I’ve just released another update to the Whiley compiler. As usual, you can access this from the downloads link on the left. This release is relatively minor, which primarily fixes a number of bugs and includes more tests. I’ve also turned off full verirfication by default, since this is really not ready yet . . . → Read More: Whiley v0.3.1 Released!
Well, after a significant amount of effort, many sleepless nights, and too many test cases going green, then red, then green, then red … it’s finally here!!!
In the process of moving from v0.2.X to v0.3.0, I have rewritten probably 75% of the code from scratch. The new version is working quite well, and . . . → Read More: Whiley v0.3.0 Released!
Well, here’s version 0.2.9. This includes numerous bug fixes, and several major feature updates:
Support for recursive algebraic datatypes Improved support for type testing, particularly of recursive types Syntax of function declarations has changed slightly to use where instead of requires + ensures. See this post for more on why.
However, there remains a . . . → Read More: Whiley v0.2.9 Released!
Well, finally, after a lot of effort I have a new release of the Whiley Development Kit. To get it, follow the download links on the left.
The major difference over the previous version is that the theorem prover has been almost completely rewritten. So, while on the surface it might not appear much . . . → Read More: Whiley v0.2.7 Released!
Testing that the Whiley-to-Java Compiler (wyjc) functions correctly is something of a challenge. We must, as usual, check that the correct (JVM) code is generated, and that the type checker is accepting/rejecting the right programs. However, we must also test that the theorem prover wyone is accepting / rejecting the right programs as well. . . . → Read More: An Overview of Whiley’s Testing Framework
So, a little update regarding the status of the Whiley compiler. I have spent a considerable amount of time redesigning the theorem prover over the last 8-12 weeks, and still haven’t managed to put everything back together. The reason for this was simply that I reached a brick wall in terms of the original . . . → Read More: Whiley Compiler Status Update
