What's Changed

Editor Integration via Language Server Protocol

You can now get error messages and hints directly inside your editor.
Most editors which support LSP should also be compatible.

We now have an official Unison Language VSCode extension!

See the language server setup guide for more information.

Here's a summary of what's new in Version M4:

Unison-native code hosting on Unison Share

Create your account at https://share.unison-lang.org and then push your code like so:

.projects.corla> push.create aryairani.public.corla

Then head over to https://share.unison-lang.org to see your rendered code and docs!
You can still upload to Github by wrapping the git repository location in git(...), like:

.projects.corla> push.create git([email protected]:aryairani/unison).corla

Self-contained namespaces

We've introduced the idea of self-contained namespaces to help keep things under control. Just fork the libraries you want into lib relative to the namespace you're working in, and the rest of the universe of code will stay out of your hair. Absolute paths are out.

New builtins

The base library has some new goodies. See the blog post for an overview.

New syntax

  • #3135 do parses as 'let now

And:

Loads of bugfixes, performance improvements, UI improvements.

Codebase Upgrade

For existing installations, Release M4 will perform an automated codebase upgrade. If prompted to upgrade, close any currently open copies of UCM, and then press Enter. Your existing codebase will be backed up automatically.

$ ucm
📋 I backed up your codebase to ~/.unison/v2/unison.sqlite3.1657826988
⚠️  Please close all other ucm processes and wait for the migration to complete before interacting with your codebase.
Press <enter> to start the migration once all other ucm processes are shutdown...

🔨 Migrating codebase to version 4...
🏗  1148 / ~1148 entities migrated. 🚧
Finished.
🛠  Cleaning up unreachable branches and causals...
🔨 Migrating codebase to version 5...
🕵️  Checking codebase integrity...

🏁 Migration complete 🏁

Let us know in Slack if you encounter any trouble with this.

Fetching the latest base library

UCM will automatically download the base library for new installations, but you can also get it manually with:

.> pull unison.public.base.releases.M4 .base

release/M3

Hi all, we have been hard at work on Unison.

UCM Milestone 3 includes:

  • New website with much-improved documentation! https://unison-lang.org and https://unison-lang.org/learn by @rlmark and @hojberg
  • Base library now has overview documentation and many new API docs on individual types and functions (for instance, Float), by @runarorama
  • Native support for Windows! Help us test it out! 🤞(None of us runs Windows.)
  • So many bug fixes, and performance improvements, and including an updated codebase format. You may want to grab a bite to eat while you wait, but your code will be migrated automatically. 🤖
  • Support for pushing and pulling from git branches and tags in Git-hosted codebases. But don't get too attached, because Unison native code hosting is in the works. 🚀
  • Many Codebase UI and Doc rendering improvements. In fact, all of the posts at http://unison-lang.org/blog are now Doc values! (Including those that embed video! 🎞)
  • Experimental support for fzf auto-completion in ucm.
  • A few new or changed UCM commands:
    • gist pushes a namespace to your remote codebase; for quickly sharing namespaces that you don't necessarily want to name.
    • pull.without-history, for when all you want is a squash merge.
    • delete.namespace.force allows you to delete a namespace that still has dependencies. (Use at your own risk, since the names will missing for the time being.)
    • api prints the UCM web api links for those who are developing against it.
    • compile.output is now compile.
  • Special thank you to external contributors: @solomon-b, @nprindle, @hagl, and @philderbeast.

Upgrading

How to upgrade from an M1 series codebase

If you're already using an M2 series release (try ucm version if unsure), you can skip this section.

If you still have a V1 codebase, ucm upgrade-codebase can be used to upgrade it to the new format. We recommend that you push the converted codebase to a fresh Git repo.

$ ucm upgrade-codebase
... wait a while for this to finish
$ ucm
.> push https://github.com/myusername/myunisoncode2

Where myusername/myunisoncode2 is a fresh Git repo.

If your codebase isn't in the default location (of ~/.unison), you can pass the --codebase flag:

$ ucm --codebase /path/to/mycode upgrade-codebase

Let us know in Slack if you encounter any trouble with this.

Fetching the latest base library

.> pull https://github.com/unisonweb/base:.releases._M2k .base_m2k

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_m2k.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_m2k.patch
.mycode2> todo .base_m2k.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.

Check out https://github.com/unisonweb/unison/issues?q=is%3Aissue+is%3Aopen+label:P1 to follow current high priority issues being worked on.

release/M2j

Our last release was M2i. Here's a summary of what's new since then:

Fetching the latest base library

.> pull https://github.com/unisonweb/base:.releases._M2j .base_m2j

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_m2j.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_m2j.patch
.mycode2> todo .base_m2j.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

  • This release adds experimental support for self-contained bytecode files (these are precompiled files that are small and package a main function and its minimal dependencies for execution with low startup times), however we learned the initial approach doesn’t work on platforms with ASLR (address space layout randomization) such as MacOS. We’re going to be redoing this in a more robust way for a later release.

What's coming in future releases?

  • More work on standalone bytecode files for running compiled Unison programs outside of UCM.
  • Changes to the PR and Update process!
  • A new docs site based on the same doc renderer used on https://share.unison-lang.org.
  • More work on Unison's distributed programming API.
  • and a bunch more...
