Does it work if you pass the flags it asks for? (before the --)

cristianoliveira commented 8 years ago

Hey @arcnmx Thanks for answering so fast :)

Which option should I pass through it?

arcnmx commented 8 years ago

Depending on which part of your source you want to run the lint over, cargo clippy --lib or cargo clippy --bin BINARY_NAME_HERE. It can't do all at the same time for a multi-crate project, basically.

Even using it. :(

 cargo clippy --lib                                                                                                     [ruby-2.2.1]

Do you have some practical example? I mean, some project that use it currently and the command that I should use.

arcnmx commented 8 years ago

That's correct. How did you install cargo-clippy?

cristianoliveira commented 8 years ago

I've downloaded this repo, compiled it and created a symbolic link to /usr/local/bin/cargo-clippy

arcnmx commented 8 years ago

Can you point to a specific codebase / github repo where you're encountering this problem? Also does which cargo-clippy point to /usr/local/bin/cargo-clippy?

cristianoliveira commented 8 years ago

The code I am trying to run on is this one: git clone git@github.com:cristianoliveira/funzzy.git

Where cargo-clippy is installed:

crosa@cristianoliveira ~/others/rust-clippy (master)$ 
which cargo-clippy
/usr/local/bin/cargo-clippy
arcnmx commented 8 years ago

works fine here on Linux... both:

cargo clippy --release --lib -- -Dclippy -Wclippy_pedantic --verbose
cargo clippy --release --bin funzzy -- -Dclippy -Wclippy_pedantic --verbose

However, you may just be better off checking out the new cargo-clippy: http://llogiq.github.io/2016/05/11/clippy.html

I've updated the nightly version of Rust to rustc 1.10.0-nightly (e0fd34bba 2016-05-09) and it worked :)
