Without this guard, the build script is rebuilt as soon as any file
within the package is changed. This includes files created by external
tools such as IDE.
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.
