v0.7: Dalry
Version 0.7 -- Dalry
Version 0.7 of Links brings many new features (some of which have been in the works for over two years!)
Handlers for Algebraic Effects
Algebraic effects abstractly specify operations, which are given meaning by handlers. These provide a powerful mechanism for designing effectful code.
Read more in Hillerström & Lindley's Liberating Effects with Rows and Handlers and in examples/handlers.
Distributed Concurrency
Whereas before, communication using session types and actor-style processes was limited to processes on the same concurrency runtime, Dalry provides the infrastructure to use these concurrency primitives across concurrency runtimes. See more in examples/distribution.
Javascript FFI
Dalry brings support for natively calling JavaScript functions from Links client code. You can read more on the wiki page.
Standard Library
Links now has support for a standard library. We are hoping to gradually move things out of the more monolithic prelude, and support more data structures and algorithms out of the box. For now, we have included a minimal node-indexed binary tree library, which you can load with open BinaryTree.
Support for Programmatic XML Construction
Links now supports the ability to create XML from variants, and variants from XML. These are implemented in the xmlToVariant and variantToXml functions.
Minor Changes
- Links now has native readline functionality by default. To turn this off, run with the
-rflag. - Many bugfixes.
