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This upgrades the versions of everything, including upgrading almost all outdated dependencies.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.
Using the cargo-hack command, which now gets installed in the Vagrant environment, there's now an easy way to make sure exa can be built and test with all combinations of features.
There have been times in the past where exa has failed to build without the git feature, and I've just never noticed. This should put a stop to that.
This commit deletes the Makefile, which contained targets to build exa and install it on the local machine, and replaces it with a Justfile, which only contains command to build and test exa.
My reasoning for doing this is as follows:
• exa is increasingly being installed through package managers, rather than built and tested locally, so users are avoiding using the Makefile at all.
• It was a pain to keep up with the correct paths for installing the binary, man pages, and completions, which can vary between OSes. By removing them, the code in this repository need only concern itself with building exa and putting its files in the 'target' directory, simplifying things.
• just is much simpler than make conceptually, which is why I prefer it. It just runs commands, rather than being a complete build system, which we already use Cargo for.
• just has features built-in, such as listing tasks, that we've had to create make targets for.
• exa only needed a Makefile at all because it pre-dates Cargo!
• Other Rust projects seem to be getting along perfectly fine without one.
If I've missed some important reason that makes it worth keeping the Makefile around then please let me know.
• Get rid of the 'fresh' VM. It just got in the way, taking up more memory when 'vagrant up' was used, and only solved one problem that was happening three years ago when I was at RustFest and in a programm-y mood.
• Use a more up-to-date Ubuntu image and give the machine more cores.
• Start moving some of the developer tools out of this repo. As I get more and more Rust projects, I don't want the scripts to package them to be repeated in each repository.
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
