Some packages seem not installable

[HenkPoley]

Saw an issue installing gren-lang/svg (not the issue at hand here), so I yak-shaved a script with codex that tries to install all packages listed under: https://packages.gren-lang.org/package

And these seem to have unrecoverable issues to install:

• blaix/gren-ansi
• blaix/gren-array2d
• blaix/gren-playground
• blaix/gren-tui
• blaix/prettynice
• gren-lang/compiler-node

For the blaix packages, I'll need to contact the author. But there's on by Gren-lang itself, possibly related to this ticket: Dependency resolver should check for compatible gren-version and platform #6

Logs here: https://github.com/HenkPoley/try-all-gren-packages/tree/main/output/errors

Common failure modes:

--CANNOT FIND COMPATIBLE VERSION----------------------------------------------

I cannot find a version of gren-lang/core that is compatible with your existing dependencies.

These are the confliction versions:

    7.2.1 <= v < 7.2.2
    6.0.0 <= v < 7.0.0

--CANNOT FIND COMPATIBLE VERSION----------------------------------------------

I cannot find a version of gren-lang/browser that is compatible with your existing dependencies.

These are the confliction versions:

    6.0.2 <= v < 6.0.3
    5.0.0 <= v < 6.0.0

The original issue with gren-lang/svg- which seems to be deprecated (for Gren) at: https://github.com/gren-lang/svg - so that makes sense that it's not installable.

Edit: Another clue what should be installed here:

https://github.com/gren-lang/gren-lang.github.io/blob/3c04f0f4936a8f3a2719ae3705eb6ac7153c15a2/articles/221212_hello_nodejs.md?plain=1#L36

Several different packages have now been consolidated into fewer, but bigger packages. For example: gren-lang/virtual-dom, gren-lang/html and gren-lang/svg are now merged into gren-lang/browser.

Shouldn't there be a meta-package that replaces those and installs gren-lang/browser? Or a nice error message from the compiler, for this special case?

    gren-lang/svg --INVALID gren.json IN gren-lang/svg------------------------------------------

An error occured while I was reading the gren.json file for this package.

The error is:

    Problem with the given value: { "type": "package", "name": "gren-lang/svg",
    "summary": "Fast SVG, rendered with virtual DOM diffing", "license":
    "BSD-3-Clause", "version": "1.0.0", "exposed-modules": { "SVG": [ "Svg",
    "Svg.Attributes", "Svg.Events" ], "Optimize": [ "Svg.Keyed", "Svg.Lazy" ] },

    < 2.0.0" }, "test-dependencies": {} } Expecting an OBJECT with a field named
    `platform`

Pretty printed:

Thank you for reporting this.

The issue with all these packages, I believe, is that they haven't been updated for the latest versino of gren yet (compiler-node will be released later this month, I hope).

This could be fixed in the package server itself (not displaying incompatible packages) and the error message from the compiler can be improved.

I'll remove mentions of gren-lang/svg from the compiler :)
