v0.42.0

Regal v0.42.0 is here! Bringing a number of improvements to both the linter, language server and debug adapter.

42 is the magic constant of the smallest non-trivial magic cube, a 3×3×3 cube with entries of 1 through 27, where every row, column, corridor, and diagonal passing through the center sums to forty-two.

Language Server

Find References and Rename

This release brings initial support for finding references and renaming symbols in the workspace. This first version
is limited to function arguments and some bindings, but we plan to expand this in future releases.

rename.mov

References are checked across the whole workspace, and renames work even when for example, a function is incrementally defined in several different files.

Thanks @SeanLedford for your work on this!

New future.keywords completion provider

The language server will now suggest future.keywords in completions for import lines — notably the new import future.keywords.not for now, with a few more to follow soon in OPA.

Debug Adapter

Evaluate

Regal's debug adapter protocol (DAP) implementation now supports evaluating variables and expressions inside of stack frames in debugging sessions! This also allows setting up watch expressions in clients like VS Code.

Make sure to download the latest version of the OPA VS Code extension to try it out. More clients hopefully supported soon!
