Changelog

[Next version]

Building/Packaging changes

• The Nix flake's buildIdris function now returns a set with executable and library attributes. These supersede the now-deprecated build and installLibrary attributes. executable is the same as build and library is a function that takes an argument determining whether the library should be installed with sourcecode files or not; other than that, library functionally replaces installLibrary.

• The Nix flake's buildIdris executable property (previously build) has been fixed in a few ways. It used to output a non-executable file for NodeJS builds (now the file has the executable bit set). It used to output the default Idris2 wrapper for Scheme builds which relies on utilities not guaranteed at runtime by the Nix derivation; now it rewraps the output to only depend on the directory containing Idris2's runtime support library.

• The Nix flake now exposes the Idris2 API package as idris2-api and Idris2's C support library as support.

Language changes

Compiler changes

NodeJS Backend

• The NodeJS executable output to build/exec/ now has its executable bit set. That file already had a NodeJS shebang at the top, so now it is fully ready to go after compilation.

Library changes

Prelude

Base

• Data.List.Lazy was moved from contrib to base.

• Added an Interpolation implementation for primitive decimal numeric types and Nat.

• Added append (++) for List version of All.

Contrib

• Data.List.Lazy was moved from contrib to base.

• Existing System.Console.GetOpt was extended to support errors during options parsing in a backward-compatible way.
