Run arbitrary code inside dagger module

[nimble idol]

I've been playing with dagger for a couple days now and one thing I occassionally run into is the desire to execute some code in the module. My most recent example is trying to extract git information from a src directory passed to the module that is a dagger.Directory type.

I believe this is just how dagger works in that I cannot find this path via code using some go module like go-git to extract the information I need. Instead I bascially have to exec a bunch of git cmds and parse the output. Is there an altnerative to this?

Run arbitrary code inside dagger module

if your module uses the Go SDK, you are free to install any go library and call it from uour dagger functions. It will work just fine

If the code I'm calling needs to interact with a directory or file in the container how can I do that? From what I could see there is no way to get the path to a dagger.Directory but may be wrong

So after searching a bit more, I see a dagger.Directory is just a snapshot - I think after using WithDirectory I can specify a mount point and from there run any code that needs access

those directories are objects that exist inside the dagger engine. Your code is on the client side. If you need access to directory contents you need to export them. See Directory.export
