This makes clap wrap the help text according to the terminal width,
which improves readability for terminal widths < 120 chars,
because clap defaults to a width of 120 chars without this feature.
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.
As discussed here: https://github.com/uutils/coreutils/pull/2361
the group IDs returned for GNU's 'group' and GNU's 'id --groups'
starts with the effective group ID.
This implements a wrapper for `entris::get_groups()` which mimics
GNU's behaviour.
* add tests for `id`
* add tests for `groups`
* fix `id --groups --real` to no longer ignore `--real`
- All assert_eq in tests/common/util.rs now print a pretty diff on test
failures.
- {stdout, stderr}_is_fixture now compare the expected output and the
fixture as Strings, which leads to more usable diffs.
* Issue #1622 port `du` to windows
* Attempt to support Rust 1.32
Old version was getting "attributes are not yet allowed on `if`
expressions" on Rust 1.32
* Less #[cfg]
* Less duplicate code.
I need the return and the semicolon after if otherwise the second #[cfg]
leads to unexpected token complilation error
* More accurate size on disk calculations for windows
* Expect the same output on windows as with WSL
* Better matches output from du on WSL
* In the absence of feedback I'm disabling these tests on Windows.
They require `ln`. Windows does not ship with this utility.
* Use the coreutils version of `ln` to test `du`
`fn ccmd` is courtesy of @Artoria2e5
* Look up inodes (file ids) on Windows
* One more #[cfg(windows)] to prevent unreachable statement warning on linux
* Implemented --indicator-style flag on ls.
* Rust fmt
* Grouped indicator_style args.
* Added tests for sockets and pipes.
Needed to modify util.rs to add support for pipes (aka FIFOs).
* Updated util.rs to remove FIFO operations on Windows
* Fixed slight error in specifying (not(windows))
* Fixed style violations and added indicator_style test for non-unix systems
* install: implement `-C` / `--compare`
GNU coreutils [1] checks the following: whether
- either file is nonexistent,
- there's a sticky bit or set[ug]id bit in play,
- either file isn't a regular file,
- the sizes of both files mismatch,
- the destination file's owner differs from intended, or
- the contents of both files mismatch.

* Add test: non-regular files
* Forgot a #[test]
* Give up on non-regular file test
* `cargo fmt` install.rs
- refactor internal version specifications to be ">=M.m.p" (where M.m.p is *already published*)
## [why]
Loosening internal version dependencies decreases the coupling between packages such
that packages can be published in a looser order. It allows the packages to be version
updated and published in tandem (ie, by using `cargo workspace ...`). Once published,
the internal versions can then be updated (again, to an *already published* package
version), as needed.
- 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.
## [why]
'textwrap' is currently unstable, with "term_size" being an undocumented, but required,
feature. The feature name has already changed within the repository 'master' branch.
But that branch has never been pushed to a new version.
Pin for now with "!maint" mark and comment.
- final multi-binary will now function correctly with any binary/executable name
- multi-binary container acts as the specified util IF EITHER ...
1. the binary/executable name exactly matches the name of an applet/util
2. the binary/exectuable name matches <PREFIX><UTIL_NAME> pattern
* where the PREFIX is any string ending in a non-alphanumeric character
.## [why]
Reorganizing and minor renaming of features within *Cargo.toml* will hopefully
help to place new utilities into the best feature set, encouraging the
"universal" / cross-platform aspect of the project.
"feat_require_..." sets are used to segregate utilities with restrictions limiting
cross-platform availability and are annotated with the reasons for the limitations.
- hotfix transitive bug in 'failure' forcing MinSRV increase to rust v1.33.0 by pinning 'backtrace' to <= 0.3.31
.# [why]
'failure' was using 'backtrace' `version = "0.3.3"`, which by semantic version
auto-upgrade was pulling in 'backtrace' > v0.3.30 (specifically, v0.3.40 most
recently). 'backtrace' v0.3.31 introduces use of `#[cfg(target_vendor = ...)]`
which requires rust v1.33.0. So, 'backtrace' is forcing an upgrade of MinSRV
to rust v1.33.0 with the change from backtrace v0.3.30 to backtrace v0.3.31.
Technically, by being less than v1.0.0, 'backtrace' has no semantic version
requirement. And there is debate about whether increasing MinSRV is a semantic
change. But, in my strong opinion, breaking our MinSRV statement is definitely
a semantic change.

Some tests failed when run using Docker because they assumed the
user would never be root. This is more of a band-aid solution.
An actual fix would be to test see if something like these tests
were to succeed when the user is root.
- adds conditional supports for unix domain sockets
- adds unix domain socket test
- adds Results to functions, removing unwraps
- uutils `cat` used to panic on broken stdout pipes (e.g. `cat
/dev/zero | head -c1`). this is fixed in this PR
- updated to exit 0 on success, and 1 if an error occurs.
- adds docstrings
- adds an error log on printing a directory
- adds categorization of other filetypes for extensible
differentiation of behaviors
- adds OutputOptions struct to replace params for extensibility
- adds correct status code on exit
`test_chmod_ugoa` and `test_chmod_many_options` both change umask, which
is global state. Since tests run concurrently, this might lead to
a situation where one of the tests changes umask to a value that screws
another test's checks. To prevent this, we introduce a mutex that should
be held by any test that changes umask.
Unfortunately, there's no way to hide umask behind this mutex and
enforce its usage: programmers will have to maintain the discipline
themselves.
Add install utility skeleton source, based on
mv, including the getopts setup mirroring
GNU's `man install` documentation. Also
add a single test and build system code.
The main motivation is to move toward running those tests for a specific
target, that is, if a test won't run on Windows, then we shouldn't build
it. This was previously the default behavior and prevented a successful
run on AppVeyor.
I borrowed this pattern from the tests in the Cargo project.
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
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.
Everything in src/common has been moved to src/uucore. This is defined
as a Cargo library, instead of directly included. This gives us
flexibility to make the library an external crate in the future.
Fixes#717.
Implemented as follows:
Usage: expr EXPRESSION
or: expr OPTION
--help display this help and exit
--version output version information and exit
Print the value of EXPRESSION to standard output. A blank line below
separates increasing precedence groups. EXPRESSION may be:
ARG1 | ARG2 ARG1 if it is neither null nor 0, otherwise ARG2
ARG1 & ARG2 ARG1 if neither argument is null or 0, otherwise 0
ARG1 < ARG2 ARG1 is less than ARG2
ARG1 <= ARG2 ARG1 is less than or equal to ARG2
ARG1 = ARG2 ARG1 is equal to ARG2
ARG1 != ARG2 ARG1 is unequal to ARG2
ARG1 >= ARG2 ARG1 is greater than or equal to ARG2
ARG1 > ARG2 ARG1 is greater than ARG2
ARG1 + ARG2 arithmetic sum of ARG1 and ARG2
ARG1 - ARG2 arithmetic difference of ARG1 and ARG2
ARG1 * ARG2 arithmetic product of ARG1 and ARG2
ARG1 / ARG2 arithmetic quotient of ARG1 divided by ARG2
ARG1 % ARG2 arithmetic remainder of ARG1 divided by ARG2
STRING : REGEXP [NOT IMPLEMENTED] anchored pattern match of REGEXP in STRING
match STRING REGEXP [NOT IMPLEMENTED] same as STRING : REGEXP
substr STRING POS LENGTH [NOT IMPLEMENTED] substring of STRING, POS counted from 1
index STRING CHARS [NOT IMPLEMENTED] index in STRING where any CHARS is found, or 0
length STRING [NOT IMPLEMENTED] length of STRING
+ TOKEN interpret TOKEN as a string, even if it is a
keyword like 'match' or an operator like '/'
( EXPRESSION ) value of EXPRESSION
Beware that many operators need to be escaped or quoted for shells.
Comparisons are arithmetic if both ARGs are numbers, else lexicographical.
Pattern matches return the string matched between \( and \) or null; if
\( and \) are not used, they return the number of characters matched or 0.
Exit status is 0 if EXPRESSION is neither null nor 0, 1 if EXPRESSION is null
or 0, 2 if EXPRESSION is syntactically invalid, and 3 if an error occurred.
Environment variables:
* EXPR_DEBUG_TOKENS=1 dump expression's tokens
* EXPR_DEBUG_RPN=1 dump expression represented in reverse polish notation
* EXPR_DEBUG_SYA_STEP=1 dump each parser step
* EXPR_DEBUG_AST=1 dump expression represented abstract syntax tree
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.
This patch begins the work of modernizing uutils to work with 1.0-ish
Rust. In particular, it
1. Updates to the latest submodules.
2. Convert mkmain.rs, mkuutils.rs, and src/uutils/uutils.rs
to new slice syntax and use of new io, fs, and path APIs.
3. Convert src/common/util.rs to new io, fs, and path APIs.
4. Convert fmt to use new APIs.
