How do you handle install-time dependencies?

[scowalt]

I want to create a package for gomerge.

This is a command line utility built in golang that contains no Windows binaries. I wanted to do what homebrew would do, which is build the binary from source, then put the binary into the user's PATH.

Building gomerge would depend on the go package at install-time. However, the current docs are a bit unclear as to how to include an install-time dependency:

Runtime dependencies are specified with the depends setting in the app manifest. Install-time dependencies are detected based on the file extensions of the urls in the app manifest.

I highly doubt that scoop will know to install golang based on my downloading of a .7z file of the source code.

For now, I will add a pre-install script that does scoop install go. However, this feels a bit hacky. For example, go will stay on the user's system if/when they uninstall gomerge, which feels like an unintended side effect. Maybe this is what homebrew does?

here's what I would do:

{
    "version": "3.1.0",
    "description": "A tool which allows you to quickly bulk merge, approve and close several pull requests from your terminal.",
    "homepage": "https://github.com/Cian911/gomerge",
    "license": "MIT",
    "depends": [
        "main/go",
        "main/make"
    ],
    "architecture": {
        "64bit": {
            "url": "https://github.com/Cian911/gomerge/archive/3.1.0.zip",
            "hash": "330f61d03b1a0f934e4e2fe051263a0efc00fa0be517f7f95fcaabbd8fd9cc87"
        }
    },
    "pre_install": [
        "make -C $dir\\gomerge-$version",
        "Move-Item $dir\\gomerge-$version\\bin\\gomerge $dir\\gomerge.exe",
        "Remove-Item $dir\\gomerge-$version -Recurse -ErrorAction SilentlyContinue"
    ],
    "bin": "gomerge.exe"
}

For example, go will stay on the user's system if/when they uninstall gomerge, which feels like an unintended side effect.

In this case: main/go and main/make is unused packages(orphans), if the user has not installed them before. but Scoop does not marks/tags packages.

I have not tested, but should work:

'main/go', 'main/make' | foreach { if (!(scoop info $_).installed) { $deps += $_ + ' ' } }
if ($deps) { scoop install $deps }
...
BUILDING
...
if ($deps) { scoop uninstall $deps }

An alternative would be to scoop install go in the pre_install, and scoop uninstall go in the post_install.
