chore(tests): New match-strict? cljs.test directive (#20825) 
Equality checks in tests using = give a bad experience by default on test
failures containing nested data structures. We use the cljs.test directive
match? from matcher-combinators library to help compare nested structures. The
problem with match? is that its default matcher for maps (embeds) can be too
permissive, and this causes surprises.

Here we upgrade matcher-combinators to latest, where a new matcher called
nested-equals is available. This matcher won't allow extra keys in maps. This
matcher eliminates the need for manually adding nested equals matchers as we
have to do currently.

- Upgrades matcher-combinators from 3.8.8 to 3.9.1 (latest as of 2024-07-19)

What changes?

When asserting in tests, we now have the option to use match-strict? or match?.
Both directives are available by integrating with cljs.test. The code
implementing the new match-strict? directive was 100% copied from the library
matcher-combinators because we need to wrap the expected value ourselves with
matcher-combinators.matchers/nested-equals. It's ugly code, but it's how we can
integrate with cljs.test/assert-expr.

Description

This folder contains the scripts and Nix derivations necessary to generate Clojure dependencies for this project.

Usage

Running generate.sh in a shell that has available shadow-cljs and clojure should update the deps.list and deps.json files.

Details

By using the following command:

shadow-cljs classpath --force-spawn

We download the necessary JARs into ~/.m2 folder, but also get the classpath printed into standard output. We skip POM files since they are not necessary, and add edge cases we don't want to handle.

We then use the classpath in combination with contents of ~/.m2 folder to generate the following files:

  • deps.list - List of JARs relative to the ~/.m2 cache folder.
  • deps.json - Full list of JARs including their SHAs.

The deps.list file is just intermediate and for debugging purposes. The deps.json is loaded by the derivation in default.nix and used to produce a derivation that contains all the necessary dependencies:

 > grep cljfmt nix/deps/clojure/deps.list
