Generating the tests to run in build.rs created problems for tooling. For example, cargo fmt, was ignoring the test_*.rs files and needed to be passed these files manually to be formatted. Now we simply use the feature mechanism to decide which tests to run.
Several binaries have been added to `hashsum` that have never been part
of GNU Coreutils:
- `sha3*sum` (uutils/coreutils#869)
- `shake*sum` (uutils/coreutils#987)
- `b3sum` (uutils/coreutils#3108 and uutils/coreutils#3164)
In particular, the `--bits` option, and the `--no-names` option added in
uutils/coreutils#3361, are not valid for any GNU Coreutils `*sum` binary
(as of Coreutils 9.0).
This commit refactors the argument parsing so that `--bits` and
`--no-names` become invalid options for the binaries intended to match
the GNU Coreutils API, instead of being ignored options. It also
refactors the custom binary name handling to distinguish between
binaries intended to match the GNU Coreutils API, and binaries that
don't have that constraint.
Part of uutils/coreutils#2930.
This adds a hidden `completion` subcommand to coreutils. When invoked with
`coreutils completion <utility> <shell>` a completion file will be printed
to stdout. When running `make install` those files will be created for all
utilities and copied to the appropriate locations.
`make install` will install completions for zsh, fish and bash; however,
clap also supports generating completions for powershell and elvish.
With this patch all utilities are required to have a publich uu_app function
that returns a clap::App in addition to the uumain function.
When invoked via '[' name, last argument must be ']' or we bail out with
syntax error. Then the trailing ']' is simply disregarded and processing
happens like usual.
- imported crate name collisions bypass implemented
## [why]
There may be some core or external crates required/used by this project that collide with
uutil names. For example, the `test` util collides with the rust core crate 'test' which
is used behind the scenes for testing. Without the renaming scheme used here, cryptic and
fatal compiler errors occur when compiling the integration tests.
For coreutils, there are two build artifacts:
1. multicall executable (each utility is a separate static library)
2. individual utilities (still separate library with main wrapper)
To avoid namespace collision, each utility crate is defined as
"uu_{CMD}". The end user only sees the original utility name. This
simplifies build.rs.
Also, the thin wrapper for the main() function is no longer contained in
the crate. It has been separated into a dedicated file. This was
necessary to work around Cargo's need for the crate name attribute to
match the name in the respective Cargo.toml.
This allows a user to create builds with or without the Unix-specific
utilities. Right now the Makefile handles this, but this is needed to
migrate away from make.
To build Unix-specific utilities (default):
cargo build
(or)
cargo build --features unix --no-default-features
To build without the Unix-specific utilities:
cargo build --features generic --no-default-features
I separated test's main() into a separate file to override Cargo's
requirement for matching crate names. I had to update the build command
to use a special extern reference for test.
Fixes issues caused by #728.
To avoid linking issues with Rust's libtest, the crate for the test
utility was changed to 'uutest'. However, the user doesn't need to see
this so a few hoops were jumped through to make this transparent.
I also updated the make rules to build the individual features first and
then uutils. This makes 'make && make test' look more organized.
Builds the uutils multicall binary containing all utils (except stdbuf)
by default. To only build a subset
`cargo --no-default-features --features <utils>`
can be used.
Whats missing is building the standalone binaries and a mechanism to
automatically disable the build of unix only utils on windows.
