Documentation
|
|
-------------
|
|
|
|
The source of the documentation is available on:
|
|
|
|
https://uutils.github.io/coreutils-docs/coreutils/
|
|
|
|
The documentation is updated everyday on this repository:

Running GNU tests
|
|
-----------------
|
|
|
|
<!-- spell-checker:ignore gnulib -->
|
|
|
|
- Check out https://github.com/coreutils/coreutils next to your fork as gnu
|
|
- Check out https://github.com/coreutils/gnulib next to your fork as gnulib
|
|
- Rename the checkout of your fork to uutils
|
|
|
|
At the end you should have uutils, gnu and gnulib checked out next to each other.
|
|
|
|
- Run `cd uutils && ./util/build-gnu.sh && cd ..` to get everything ready (this may take a while)
|
|
- Finally, you can run tests with `bash uutils/util/run-gnu-test.sh <test>`. Instead of `<test>` insert the test you want to run, e.g. `tests/misc/wc-proc.sh`.

Code Coverage Report Generation
|
|
---------------------------------
|
|
|
|
<!-- spell-checker:ignore (flags) Ccodegen Coverflow Cpanic Zinstrument Zpanic -->
|
|
|
|
Code coverage report can be generated using [grcov](https://github.com/mozilla/grcov).
|
|
|
|
### Using Nightly Rust
|
|
|
|
To generate [gcov-based](https://github.com/mozilla/grcov#example-how-to-generate-gcda-files-for-a-rust-project) coverage report
|
|
|
|
```bash
|
|
$ export CARGO_INCREMENTAL=0
|
|
$ export RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort"
|
|
$ export RUSTDOCFLAGS="-Cpanic=abort"
|
|
$ cargo build <options...> # e.g., --features feat_os_unix
|
|
$ cargo test <options...> # e.g., --features feat_os_unix test_pathchk
|
|
$ grcov . -s . --binary-path ./target/debug/ -t html --branch --ignore-not-existing --ignore build.rs --excl-br-line "^\s*((debug_)?assert(_eq|_ne)?\#\[derive\()" -o ./target/debug/coverage/
|
|
$ # open target/debug/coverage/index.html in browser
|
|
```
|
|
|
|
if changes are not reflected in the report then run `cargo clean` and run the above commands.
|
|
|
|
### Using Stable Rust
|
|
|
|
If you are using stable version of Rust that doesn't enable code coverage instrumentation by default
|
|
then add `-Z-Zinstrument-coverage` flag to `RUSTFLAGS` env variable specified above.
|
|
|
|
|
|
pre-commit hooks
|
|
----------------
|
|
|
|
A configuration for `pre-commit` is provided in the repository. It allows automatically checking every git commit you make to ensure it compiles, and passes `clippy` and `rustfmt` without warnings.
|
|
|
|
To use the provided hook:
|
|
|
|
1. [Install `pre-commit`](https://pre-commit.com/#install)
|
|
2. Run `pre-commit install` while in the repository directory
|
|
|
|
Your git commits will then automatically be checked. If a check fails, an error message will explain why, and your commit will be canceled. You can then make the suggested changes, and run `git commit ...` again.
|
|
|
|
### Using Clippy
|
|
|
|
The `msrv` key in the clippy configuration file `clippy.toml` is used to disable lints pertaining to newer features by specifying the minimum supported Rust version (MSRV). However, this key is only supported on `nightly`. To invoke clippy without errors, use `cargo +nightly clippy`. In order to also check tests and non-default crate features, use `cargo +nightly clippy --all-targets --all-features`.
