List build dependencies of a store item

List build dependencies of a store item

I am customizing the git-minimal package, and for some reason python is
getting rebuilt from source, and I'm not able to figure out why.

I can recursively list/graph runtime dependencies (references) of a
store item using the following commands.

guix size /gnu/store/...
guix graph -t references /gnu/store/...

How do I list the build dependencies (inputs of the build derivation) of
a store item?

Thanks,
Arun.

I think a store item doesn't know where it comes from, so you can only find its runtime references. If you have a package foo, you can find its build-time dependencies with guix graph:

guix graph foo

There's even a script that was shared here to show the path between two nodes of a guix graph, but I can't find it anymore.

That's a good point. I missed that.

Indeed, this is what I want but for a modified version of a package
defined in a file. I realized I could do it with

guix graph -e '(load "/path/to/file.scm")'

However, it might be nicer to have something like

guix graph -f /path/to/file.scm

similar to

guix build -f /path/to/file.scm

Yes, I remember such a script too. It would be very useful to have. But,
even I am unable to find it. If someone knows where to find that script,
please share a link.

The script is here:

Yes, this is the one. Thank you!

I assume git-minimal is used for the guile-git bindings, and I don't
think that shows up in the graph.

I figured this is due to git-minimal depending on curl which in turn
depends on python as a native-input.

guile-git only depends on libgit2.
