Add support for elm-test-rs

[lydell]

This involves:

• Easy: Adding links to the executables in https://github.com/lydell/elm-tooling.json/blob/main/helpers/known-tools.ts
• Medium: Adding support for .zip files on macOS and Linux (so far only elm-format for Windows uses .zip: https://github.com/lydell/elm-tooling.json/blob/5ad521d58dfd6ef98398ed00c77b065eeb0ac199/commands/install.ts#L602-L607). I think this needs to use the unzip executable if it’s available – it seems to be available on Alpine Linux. Alternatively, convince @mpizenberg to use .gz or .tgz, at least on non-Windows. EDIT: Next version is .tar.gz, should be easy to do.
• Decision: Deciding if elm-tooling init should include elm-test-rs or not. Currently that command includes the latest version of all known tools, but maybe we don’t want to include elm-test-rs until it’s considered more stable or is more popular.
• Decision: Deciding if we should wait for elm-test-rs to become more stable first. elm-tooling is built around the fact that the tools it supports are slow and stable. For a tool with rapid releases, I would have to release new elm-tooling versions all the time.

I don't mind using whatever is more convenient. For the time being I'm making elm-test-rs releases manually so I can easily change the compression format.

I don't intend to make frequent releases after 1.0.0. There might be a couple releases before that, depending on what bugs people find and completion of some features like the json and junit reports that are not finished (I haven't touched those since march or april). After that, the current set of features is enough for my usage, so updates will mostly be contributor-based or security patch I suspect.

I just published version 0.5 with some fixes: https://github.com/mpizenberg/elm-test-rs/releases/tag/v0.5
The linux and mac executable are packaged with .tar.gz and still .zip for windows. Is this more adequate for elm-tooling?

[lydell]

Yes, that’ll mean less coding on the elm-tooling side. All that should be needed is adding .tar.gz as an alias for .tgz. 👍

[lydell]

This is the plan:

1. Wait for X days to pass with no new release of elm-test-rs, then add it. Not sure what X should be, maybe 30?
2. Don’t add it by default in elm-tooling init. People will have to opt in.

The reason for 1 is, that you would need to patch the cli each time something is released?

[lydell]

@razzeee Correct!

[mpizenberg]

Just a note to let you know that a month may pass without a version because I'm busy at work now. But a new version is intended after that in the coming weeks.
