Get all dependencies‘ source files

[basbebe]

Is there an elegant way to access the source files of all cargo dependencies?

There is $CARGO_HOME if I use cargoArtifacts but I guess there is currently no way to access them individually using nix?

In my case I'm looking for a way to include e.g. all LICENSE files of all dependencies.

Hi @basbebe ! Technically it is possible to crawl the entire contents of the vendor directories and access crate sources that way, but I'm afraid there's no elegant ways that I know of (even outside of the Nix sandbox).

If your dependency licenses are all you are interested in, I'd recommend taking a look at something like cargo deny or cargo license. Hope this helps!

I am already using cargo-deny and cargo-license.

Where crates use a license-file or a license that needs a copyright notice to be included I would like to include those files from the source and automate this process.

So yes, crawling $CARGO_HOME is probably what I will have to do then.

I was hoping there was something like a passthru with a list of the dependencies' source derivations that I just overlooked 😅

Thanks though!
