does not compile with rustc 1.15.0-nightly (1c448574b 2016-11-28)

A ton of stuff seems to have been renamed. Errors can be seen here: https://travis-ci.org/durka/guard/jobs/180149918#L253

this is not a fun one... I'm compiling already, but getting crashes in rustc and clippy when testing...

[nordlow]

Does it compile with 1.13 or 1.14?

[mcarton]

It compiles with rustc 1.15.0-nightly (2217bd7 2016-11-25).
The latest version of clippy won't compile on versions as old as 1.13 or 1.14 though. It requires (and has always required) a recent nightly (usually the latest, but we've ran into some problems with that one).

[nbigaouette]

I was able to compile/install clippy yesterday using a nightly from November 25th. That's the last one that worked for me.

rustup toolchain install nightly-2016-11-25
rustup run nightly-2016-11-25 cargo install clippy
rustup run nightly-2016-11-25 cargo clippy

[nordlow]

Should I start with

curl -sSf https://static.rust-lang.org/rustup.sh | sh -s -- --channel=nightly

?

[nbigaouette]

@nordlow use https://rustup.rs/ instead. Not yet official, but close! It is official, just not 100% ready yet.

[nordlow]

Ok, I'm trying it out now. I chose nightly. Ok?

[nbigaouette]

Just follow the instruction from the site to install it (it's going to ask you questions, can't remember which ones though).

Once rustup is installed, just run the three commands I've posted:

rustup toolchain install nightly-2016-11-25
rustup run nightly-2016-11-25 cargo install clippy
rustup run nightly-2016-11-25 cargo clippy

This will install clippy using the nightly from November 25th, and run it on your code base.

You can always install a "latest" nightly, beta or stable. Refer to https://github.com/rust-lang-nursery/rustup.rs for more info.

What does cargo clippy do? Activate it as a compiler plugin?

What does cargo clippy do?

It runs clippy on the current project.

[nbigaouette]

Clippy can be run multiple ways. One of those is through a "cargo-clippy" binary, which was installed using cargo install clippy.

I basically runs clippy on your files, without having to annotate the source files or add clippy to your Cargo.toml.
