This changes the --help text, and gets rid of the special behaviour for --help --long, which I thought was a really good idea at the time, but now I just think it's inconsistent and unexpected behaviour. --help should return the same help, no matter what other arguments you have typed.
Other things:
• Put --help and --version in a section
• Capitalisation consistency
• Alignment
• Move the --octal-permissions line up a bit
• Simplify the printing implementation (HelpString is now a unit struct)
This _finally_ makes all the extended tests pass.
This commit fixes a couple of Clippy warnings, and adds the list of lints we're OK with.
It does raise some important warnings, such as those to do with casting, which aren't allowed so they can be fixed later.
This was being passed around everywhere as a parameter, when it can exist just as nicely as a struct field. This means many functions can take one argument less.
This was meant to be a small change, but it spiralled into a big one.
The original intention was to separate OptionsResult and OptionsError. With these types separated, the Help and Version variants can only be returned from the Options::parse function, and the later option-parsing functions can only return success or errors.
Also, Misfire was a silly name.
As a side-effect of Options::parse returning OptionsResult instead of Result<Options, Misfire>, we could no longer use unwrap() or unwrap_err() to get the contents out. This commit makes OptionsResult into a value type, and Options::parse a pure function. It feels like it should be one, having its return value entirely dependent on its arguments, but it also loaded locales and time zones. These parts have been moved into lazy_static references, and the code still passes tests without much change.
OptionsResult isn't PartialEq yet, because the file colouring uses a Box internally.
I read through every file and applied a couple of rustfmt suggestions. The brace placement and alignment of items on similar lines has been made consistent, even if neither are rustfmt's default style (a file has been put in place to enforce this). Other changes are:
• Alphabetical imports and modules
• Comma placement at the end of match blocks
• Use newlines and indentation judiciously
• Spaces around associated types
• Spaces after negations (it makes it more clear imho)
• Comment formatting
• Use early-returns and Optional `?` where appropriate
These are holdovers from how I used to write Rust ("back in the day" of 2014). There are still some places in the code where I think it's worth glob-importing enums, but not these places.
This commit makes changes to the way variables are referenced:
• Make types Copy when possible
• Make methods take `self` instead of `&self` where possible (trivially_copy_pass_by_ref)
• Remove unnecessary borrowing (needless_ref)
• Remove unnecessary cloning (clone_on_copy)
• Remove `ref` from match arms where possible (new Rust match ergonomics)
This commit uses Clippy to fix all the 'use_self' warnings. Using Self instead of the type name has been good Rust style for a while now, and it's become the style I'm used to seeing.
Exa::from_args used to be in the library, called by the binary, but now the binary is gone, it no longer needs to be as abstract. Instead of accepting a reference to a Write value, it takes a Stdout directly, which it owns itself, simplifying the type signature drastically.
This upgrades the versions of everything, including upgrading almost all outdated dependencies.
• number_prefix had some backwards-incompatible changes. It now feels more Rustful, and spells "Mebi" correctly.
• term_grid stopped working when I upgraded it, worryingly, so I reverted it back.
This commit removes the env_logger dependency, replacing it with a simple implementation. Doing so removes like ten other transitive dependencies that no longer need to be included in the build.
It also gains the ability to enable trace-level logging. The users crate, which contains such logging statements as of the version I published a few days ago, has been upgraded to celebrate.
Also, change the log imports to globs. I'm only interested that a file doing logging, not what level it's logging at.
This commit removes the library portion of exa. Cargo now only builds a binary.
The original intent was for exa to have its own internal library, and have the binary just call the library. This is usually done for code cleanliness reasons: it separates the code that implements the purpose of the program (the "plumbing") from the code that the user interacts with (the "porcelain"), ensuring a well-defined interface between the two.
However, in exa, this split was in completely the wrong place. Logging was handled in the binary, but option parsing was handled in the library. The library could theoretically print to any Writer ("for testing", it said), but it's far easier to run integration tests by executing the binary than to change the code to handle unit tests, so this abstraction isn't gaining us anything.
I've also had several people ask me if exa should be packaged for Linux distributions as a library, or just a binary. Clearly, this is confusing!
In several of my other Rust projects, I've done this better, with the command-line option parsing and log printing done on the binary side. It also turns out that you don't need to have a [lib] section in the Cargo.toml, so that's gone too.
It doesn't seem right to use the EXIT_SUCCESS constant in one place, and a hard-coded 2 in another. What if they overlap?
Changing the success value to 0 should be OK, though, because the standard defines 0 as success, regardless of whether EXIT_SUCCESS is 0 or not.
Also, the values have become i32s. The Rust function std::process::exit takes an i32, so there's not much point using anything else.
This was an unintended consequence of #653. The Files iterator stopped using IgnoreCache and started using GitCache, which would always populated when the `--git` option was passed, without checking whether files were meant to be ignored. This meant that passing `--git` started ignoring files even without `--git-ignore`.
The solution for now is to explicitly pass the flag around, which probably should be a better type than bool but isn't. This makes the git-ignoring-related extended tests pass.
Instead of defaulting immediately to /etc/filename for the timezone, we can first check whether the TZ environment variable is set. If so, we can pull the corresponding timezone file from /usr/share/zoneinfo. Closes#453.
Using --octal_permissions will insert another column before the existing
permissions where permissions are encoded using octal values as
requested in #316
Added the following imemdiate file types for PHP:
- `composer.json` for [Composer](https://getcomposer.org/), the defactor standard package manager for PHP;
- `RoboFile.php`, for [Robo](https://robo.li/), the PHP task runner.
Note: [Phing]() uses `build.xml`, which was already included in the list.
Previously if a timestamp was unavailable, it defaulted to the epoch.
Prior to this it defaulted to a zero duration.
Switch to an Option<SystemTime> and move the handling of unavailable
timestamps to rendering.
Fix an off-by-one on the seconds when subseconds are present, and
correct display of nenoseconds, which are of course inverted due to the
internal value being negative.
Instead of returning a Duration since the epoch from file metadata,
which cannot represent times before it, return the SystemTime directly.
Move conversion closer to where it's needed, and perform it infallibly.
pom.xml (Maven) is popularly used for Java projects, along with the
already existing build.xml (Ant) and build.gradle (Gradle) immediate
files.
zwc stands for Zsh Word Code and contains compiled Z Shell scripts or
functions.
- Checking on a directory doesn’t tell us if supported elsewhere
(some filesystems, like tmpfs, don’t support created time)
- We want to be able to display a column even if some subfiles or
subdirectories don’t support it
So now if unsupported a time of zero is used, and displayed as `-`
