Hi Guix,

I have been writing a lot of Rust recently. Racer provides
autocompletion. It uses the source of rust standard libraries among
other tools.

There are two items I paid close attention to:

1. Add a "source" output for rust.  This roughly corresponds to the
rustup component.  Using the rustup toolchain to manage rust tooling the
command would be: rustup component add rust-src. However, using guix, we
already have the source.

2. Racer requires features that are not in the stable branch of rust.
Unfortunately this is not any fault of racer. Racer uses crates from
rustc which uses unstable features.  To get around this, I built
racer using the undocumented and unsupported RUSTC_BOOTSTRAP environment
variable. Perhaps the better future solution would be to provide a
nightly rustc and use that to compile racer.

I hope someone gets some use out of racer!

- John

How about we use the source of rust itself for the rustc-ap packages?
That way, updating rustc won't actually ever break because of RUSTC_BOOTSTRAP,
since the use of the unstable features comes from the same source of
truth that will actually compile them.

Hi Jakub,

Sorry I am late to respond.

I like the idea of keeping racer up to date with rust. Do you think making racer an output of rust would be good or is a separate package depending on rust a better option?

Thanks!

John

Hi Jakub and Efraim,

I agree with Jakub that racer-like packages would be most helpful if
provided as an output of rust. There are plenty of other places where
this guarantee is not provided like cabal-install. But, since racer is
now superceded by rls and rust-analyzer, I am going to close this. Rls
and rust-analyzer are both outputs of rust after 1.46 and it has been
shown to work for rustfmt already.

Thanks again,

John
