dagger.File from root of the project

[vapid ridge]

So this works when I copy my .golangci.yaml inside the dagger module.

config := dag.CurrentModule().Source().File(".golangci.yaml")

But I want that file inside the root of the project, I tried:

config := dag.CurrentModule().Source().Directory("..").File(".golangci.yaml")

But that doesn't seem to work, I think cause the file doesn't get transfered to the engine.

Thanks!

yes, this is correct. When you call a module, CurrentModule.Source() only returns the files that are part of the module source

if you need files from the root of your project, you'll have to pass them as function arguments

@shell hazel thanks for the quick response as always! I don't want to give the config on each lint request, is there a way to abstract that away for the user?

[shell hazel]

yes, since v0.12.6 you can use context directories https://github.com/dagger/dagger/pull/7744

it's not documented yet (we're writing the docs at this moment), but the idea is that you can specify a *dagger.File as a function argument and use the // +defaultPath pragma to set it whatever file you need

that way the user doesn't have to specify anything

[vapid ridge]

This would mean I would upload my whole repo to my dagger-engine and then later the code to lint, right?

[shell hazel]

you can upload just a single file if needed. Depending what you're trying to do

[vapid ridge]

Ohh, so providing a context doesn't mean it gets uploaded. Ok, thats nice.

[shell hazel]

it does, but you can provide a single file as the context

in this case you could only upload the .golangci-lint.yml file from the root of your repo

Can you please give me an example on howto annotate that here:

https://github.com/go-orb/plugins/blob/main/.github/main.go#L114 ?

I edited the file and line as i moved the dagger folder into .github 🙂

[shell hazel]

adding a new argument to that function with:

// +defaultPath="/.github/.golangci.yaml"
golangciConfig *dagger.File

I think that should be enough

It's not that the file is the context, but rather that the file can default to a path within your context dir (usually your git repo)

[vapid ridge]

@shell hazel @clever lichen it works. Thanks for that 🙂 As a little thank you I wrote an article in demos.
