The number of necessary columns was computed by producing a grid in different sizes and see if all columns were used. However, if there was two files and we tried to fit them in a 3-column grid, it would produces three headers and all three columns would be used; when trying a 4-column grid, the two supplementary headers would fill the third column and the fourth would be empty; so 3 columns would be used.
Now, when the grid fits into the terminal and the number of columns is exactly the number of files to display, it returns immediately instead of trying bigger grids.
Fixes GH-436.
This is only visible when selecting both icon and file name, as most terminal emulators then invert background and foreground color.
It also workaround a Konsole bug: https://bugs.kde.org/show_bug.cgi?id=422776
The flags --git and --git-ignore are caught early during options parsing, so no more checking for git feature is done elsewhere.
Since --git-ignore depends on git too since recently, remove it from help when git feature is disabled.
Extended attributes now don’t artificially depends on git feature being enabled.
This commit remove the extra space that was added between icons and file names in commit 128fadd, and adds an option to put them back.
Re-fixes GH-619 and fixes GH-541.
The rationale here is that there's more of a background colour than the foreground colour when painting text, and having a gap of no background colour in between the icon and the file name looks weird.
Fixes GH-561.
exa now bases the icon style for a file on its file name and kind in all cases, rather than just on its file name. This means that directories and symlinks have the correctly-coloured icon.
It also only takes the foreground colour into account while styling the icon, to make sure they're not bold or underlined.
Fixes GH-528.
This commit makes adding icons to file names something that the file name renderer does, rather than something that each individual view does. This is now possible thanks to the previous commit a1869f2, which moved the option to do this into the same module. The repeated code has been removed.
It happens to fix a bug where the width of each column was being incorrectly calculated for the grid-details view, making lines slightly too long for the terminal because the icon wasn't being taken into account.
All four of the view mode command-line argument parsers tested for the --icons option. Because it was common, the behaviour has been moved to the struct that handles file styles, meaning it can be parsed in one place.
This is a better place for it, as the icons are to do with the file name, not the view. It also means that the lines view has no options left for it, which is fitting.
This commit changes the way the View (long mode, lines mode, grid mode, etc) is parsed from the command-line arguments.
Previously, it checked for long and long-grid, then tree, then lines, then grid, in that order, no matter which order the arguments were given in on the command-line. Now, it bases the view on whichever argument comes last in the list.
Unfortunately, the options-parsing code for Views is getting really complicated, but I can't see a way to simplify it while retaining the existing functionality.
It also links the parsing of DirAction to the result of parsing the View, so that you can't use tree mode if your view isn't Details. This is to fix an issue where `exa --tree --oneline` would just emit ".", because the DirAction was treating directories as files, and the argument was ".", and the View made it use lines view. Now, the --tree is ignored, as the view isn't Details.
Fixes GH-407 and GH-583.
This commit significantly refactors the way that options are parsed. It introduces the Theme type which contains both styling and extension configuration, converts the option-parsing process into a being a pure function, and removes some rather gnarly old code.
The main purpose of the refactoring is to fix GH-318, "Tests fail when not connected to a terminal". Even though exa was compiling fine on my machine and on Travis, it was failing for automated build scripts. This was because of what the option-parsing code was trying to accomplish: it wasn't just providing a struct of the user's settings, it was also checking the terminal, providing a View directly.
This has been changed so that the options module now _only_ looks at the command-line arguments and environment variables. Instead of returning a View, it returns the user's _preference_, and it's then up to the 'main' module to examine the terminal width and figure out if the view is doable, downgrading it if necessary.
The code that used to determine the view was horrible and I'm pleased it can be cut out. Also, the terminal width used to be in a lazy_static because it was queried multiple times, and now it's not in one because it's only queried once, which is a good sign for things going in the right direction.
There are also some naming and organisational changes around themes. The blanket terms "Colours" and "Styles" have been yeeted in favour of "Theme", which handles both extensions and UI colours. The FileStyle struct has been replaced with file_name::Options, making it similar to the views in how it has an Options struct and a Render struct.
Finally, eight unit tests have been removed because they turned out to be redundant (testing --colour and --color) after examining the tangled code, and the default theme has been put in its own file in preparation for more themes.
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

- `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.
