Hi Guix!

I work with rust for my job and I would love to be able to use clippy
and the other tools that are in the rustc tree. This patch installs
those tools as other outputs in the same way we have cargo and rustfmt
now. Thanks!

All the best,

John

Here is an edited patch. I had rebased incorrectly, my apologies.

Rebased on staging.

There is one more question that I have about search paths. A lot of rust
tools use the $RUST_SRC_PATH to find the source of rust. I add the
source output as "src" but I am not sure how to specify a search path to
the top directory of a separate output. Any pointers?

Thanks!

Hi Jakub,

Thanks again for your work on rust.

I cc'd you for feedback on adding the "extended" tools to rust's
outputs.

I don't think tools beyond rustc and cargo should be included in the
main rust package, as this causes them to be built in each step of the
bootstrap. I believe a better approach would be to define separate
packages for them.

We would have something like

;; TODO(staging): Bump this variable to the latest packaged rust.
(define-public rust rust-1.45)

+(define-public rust-for-tools rust-1.50)

I'm not sure if rustbuild can be convinced to not build the compiler
itself when the version used for the build is the same as the sources'.
If so, defining packages for each tool shouldn't need any guix-side
tricks.

Otherwise, I would define a single rust-tools package with
(outputs '("rustfmt" "clippy" ...)). Perhaps it would help with UX if
rust-tools itself was hidden, and instead the tools would be exposed
with simple packages that expose each tool separately, with a symlink or
similar.

I'll see if I can find some time to try this out this week.

Regards,
Jakub K?dzio?ka

Yeah that would make sense. Have we explored any of the incremental or
--keep-stage options to speedup the bootstrap?

Even if it did build the compiler for each tool it may not be a problem
if only the last 3 versions had the tools available (for instance).

I could see this working nicely. I think this is just more evidence for
language-environment related documentation.

Thanks! That would be helpful. It is really painful to have all these
unmerged patches to rust.

Kindly,

apteryx mentioned some experiments with those on #mrustc.

Those weren't fruitful, but I didn't push it; I think it caused cargo to
fail compiling itself, or its test suite.
