Our last release was M2h. Here's a summary of what's new since then:

  • Many improvements to the pretty printer for round-trip code editing. Thanks @runaroama!
  • cd .. at long last! You can move up one level in a namespace structure.
  • Codebase creation workflow improvements - work by @hojberg and @rlmark
    • The former codebase creation command ucm init --codebase myNewCodebase has been deprecated in favor of a command line flag to the ucm ucm --codebase-create myNewCodebase which also opens the codebase
  • New Scope s ability for local mutable operations which are externally pure
  • New Ref type for mutable references which to which you can be read or written to using IO. Thanks @dolio!
  • New builtin functions:
    • Builtins for working with compression: Bytes.zlib.compress, Bytes.zlib.decompress, Bytes.gzip.compress, Bytes.gzip.decompress @pchiusano
    • New unsafe.coerceAbilities builtin. @dolio
    • Added new Ref and Scope @dolio
    • Added IO.systemTimeMicroseconds - thank you @alvaroc1!
    • Added Term.Link.toText @stew
    • Added Any.unsafeExtract @stew
    • Added Code.validate for testing/debugging @dolio
    • Added Code.display for displaying Code
  • Defining structural abilities and types requires structural keyword. @hojberg and @rlmark
  • Codebase UI
    • Source is now independently collapsable and are part of the "zoom cycle" triggered by the space key.
    • Signatures of open definitions are now displayed before docs. They are collapsed if there are docs and expanded when there are none.
    • Support switching perspective to a namespace. Switch perspective via the sidebar or an open definition.
    • Support namespace perspectives both overall and adhoc in the Finder via a context menu on any open definition
    • Docs render a lot nicer and Readme's of namespaces render by default when a namespace is the perspective
  • ... aaand more! See the full list of PRs merged below.

Fetching the latest base library

.> pull https://github.com/unisonweb/base:.releases._M2i .base_m2i

You can then (optionally) delete.namespace any old versions of base you have laying around. This will complain if you're still referencing definitions from the old version of base.

If you have definitions that depend on old definitions, you can find that out by doing:

.mycode> todo .base_m2i.patch

If you do have things todo, applying the patch to your namespace will replace the old versions with the new. We recommend forking a copy of your namespace before doing this:

.> fork mycode mycode2 
.mycode2> patch .base_m2i.patch
.mycode2> todo .base_m2i.patch

Assuming that reports "Nothing to do", you can delete.namespace mycode and then delete.namespace your old version of base. If you encounter any trouble, stop by the Slack in #alphatesting and we can help.

Known issues

  • Adding definitions with default metadata to large namespaces (e.g. base) may be slow. This will be fixed in an upcoming release

What's coming in future releases?

  • Usability and performance improvements for UCM, particularly around the update process.
  • Standalone bytecode files for running compiled Unison programs outside of UCM.
  • A new docs site based on the same doc renderer used on https://share.unison-lang.org
  • A first release of Unison's distributed programming API, initially just supporting local concurrent execution.
  • and a bunch more...
