checkver matches not available when using scoop install app@version

[simonmcconnell]

Installing a specific version scoop install elixir@main using my attempt at updating the manifest fails because the substitutions are passed as an empty hashmap.

Installing a specific version scoop install elixir@main using the current manifest in the main bucket fails because it tries to download vmain.zip instead of main.zip.

Scoop/lib/manifest.ps1

Line 146 in d337bb1

Invoke-AutoUpdate $app "$(Convert-Path (usermanifestsdir))\$app.json" $manifest $version $(@{ })

What I want to be able to do is install main*.zip as well as v<version>.zip but it is not as easy as I was hoping.

I attempted to use the below manifest but it does not like it when you specify a version to install.

{
    "version": "1.16.2",
    "description": "A dynamic and functional programming language designed for building scalable and maintainable applications.",
    "homepage": "https://elixir-lang.org/",
    "license": "Apache-2.0",
    "suggest": {
        "Erlang compiler": "erlang"
    },

    "hash": "0161578ce5988e286eafd2ee1b6b1999ac69c6a1b226209e332b9e9db1522dcb",
    "env_add_path": "bin",
    "checkver": {
        "url": "https://github.com/elixir-lang/elixir/releases/latest",
        "regex": "(?<vversion>[v|V]{1}(?<version>\\d\\.\\d+\\.\\d+))"
    },
    "autoupdate": {
        "url": "https://builds.hex.pm/builds/elixir/$matchVversion.zip",
        "hash": {
            "url": "https://builds.hex.pm/builds/elixir/builds.txt",
            "regex": "$version [a-zA-Z0-9]+ \\d{4}-\\d{2}-\\d{2}T\\d{2}:\\d{2}:\\d{2}Z $sha256"
        }
    }
}

This is the current manifest in the main bucket:

        }
    }
}

worst case, the wiki should be updated to inform you that they're not available when installing specific versions.
