@ -143,25 +143,20 @@ when a pull request contains unformatted code. Using `--write-mode=diff` instruc
rustfmt to exit with an error code if the input is not formatted correctly.
It will also print any found differences.
(These instructions use the nightly version of Rustfmt. If you want to use the
Syntex version replace `install rustfmt-nightly` with `install rustfmt`).
A minimal Travis setup could look like this:
```yaml
language: rust
cache: cargo
before_script:
- export PATH="$PATH:$HOME/.cargo/bin"
- which rustfmt || cargo install rustfmt-nightly
- rustup toolchain install nightly
- rustup component add --toolchain nightly rustfmt-preview
- which rustfmt || cargo install --force rustfmt-nightly
script:
- cargo fmt -- --write-mode=diff
- cargo +nightly fmt --all -- --write-mode=diff
- cargo build
- cargo test
```
Note that using `cache: cargo` is optional but highly recommended to speed up the installation.
## How to build and test
`cargo build` to build.
