* When working on rust/cargo projects of varying sizes, it may be useful
to either build all possible features (i.e. lint all possible
conditionally compiled code), or even turn off other features for a
quicker edit-lint cycle (e.g. for large projects with large build times)
* Added a g:ale_rust_cargo_default_feature_behavior flag for instructing
cargo to not build any features at all (via `--no-default-features`),
building default features (via no extra flags), or building all possible
features (via `--all-features`)
* Also added a g:ale_rust_cargo_include_features flag for including
arbitrary features to be checked by cargo. When coupled with
g:ale_rust_cargo_default_feature_behavior this allows for full
customization of what features are checked and which ones are ignored
Typically proto files depend on and make use of proto definitions in
other files. When invoking protoc user can supply paths to inspect for
dependencies.
This patch makes it possible to configure flags passed to protoc. This
makes it e.g., possible to change include paths of the linter's protoc
invocation.
The test already handled arbitrary paths reasonably well, but setting
the directory interfered via leakage with others tests for some reason.
This patch removes the call to `SetDirectory` in the fixture setup and
the subsequent cleanup in the teardown as they are not required.
On macOS, Apple's command line toolchain installs very old `tidy`
command (It was released on 31 Oct 2006). It does not consider new specs
such as HTML5 so we should avoid it.
rustfmt normally acts on a file in place, and applies configuration
from rustfmt.toml files according to the path of the file.
Using a temporary file for rustfmt breaks this functionality, so
removing the '%t' from the rustfmt command.
