This changes the way that views are used to display the actual lists of files. It used to pass empty vectors to the view methods, which most of the time would not print anything because there are no files to list — except when there’s a header row which gets printed for no files.
By not calling the view method at all when there’s nothing to print, exa won’t ever print extra things in the view unless it needs to for a file.
This fixes#106 “Don’t print the header if the result set is empty”
See the README section for more details. Basically, with this way, we can store a bunch of existing valid exa outputs, change a VM's environment to match our values, then check that exa still works by comparing outputs.
Now when you do `--sort time` instead of saying "unknown option --sort
time" it will say "unknown options '--sort time' (choices: name...)"
with all legal options.
This also adds the legal values to the default help text.
You could use src/*.rs src/*/*.rs src/*/*/*.rs,
but explicit listing is prefered.
Ideally, you should be separate object files that
are rebuilt only when necessary, and then build
the final binary from those. But have not looked
at how to compile rust code so I don't know how
to do that, and since there are no header files
that is also probably suboptimal.

Let the package manager do it. You don't want to
force stripping, the symbols are useful for debugging.

You need cargo, not rustc, and cargo requires rustc,
so checking for rustc is incorrect. And the user will
know that she needs cargo when the command cannot be
find, so why look for it and add extra dependenices
just for that.

Use quotes to support spaces and such.
Use -- to support dashes.
And most important:
Use DESTDIR to support installing into a staging directory.
This is useful for packaging and verifying the install.

This commit removes the 'main' function present in main.rs, renames it to exa.rs, and puts the 'main' function in its own binary. This, I think, makes it more clear how the program works and where the main entry point is.
Librarification also means that we can start testing as a whole. Two tests have been added that test everything, passing in raw command-line arguments then comparing against the binary coloured text that gets produced.
Casualties include having to specifically mark some code blocks in documentation as 'tests', as rustdoc kept on trying to execute my ANSI art.
The original options was becoming a bit unwieldy, and would have been even more so if I added the same amount of comments. So this commit splits it up.
There's no extra hiding going on here, or rearranging things within the module: (almost) everything now has to be marked 'pub' to let other sub-modules in the new options module to see it.
The trait was only used internally to the options module, so it doesn't actually need to be exist or implemented on anything! We can just impl them directly on the types and have those methods be local to the module.
This commit moves file, dir, and the feature modules into one parent 'fs' module. Now there are three main 'areas' of the code: main and options, the filesystem-touching code, and the output-displaying code.
It should be the case that nothing in 'output' touches 'std::fs'.
Fixes#108. MetadataExt now returns direct numeric types rather than platform-specific ones, so we need to adjust the functions that use these to have the new types. I've just aliased the types to specific ones so the rest of the code remains the same (file.rs is the only place that uses this)
The RFC that changed this is here: https://github.com/rust-lang/rust/pull/31551
This commit changes all the views to accommodate printing each path's prefix, if it has one.
Previously, each file was stripped of its ancestry, leaving only its file name to be displayed. So running "exa /usr/bin/*" would display only filenames, while running "ls /usr/bin/*" would display each file prefixed with "/usr/bin/". But running "ls /usr/bin/" -- without the glob -- would run ls on just the directory, printing out the file names with no prefix or anything.
This functionality turned out to be useful in quite a few situations: firstly, if the user passes in files from different directories, it would be hard to tell where they came from (especially if they have the same name, such as find | xargs). Secondly, this also applied when following symlinks, making it unclear exactly which file a symlink would be pointing to.
The reason that it did it this way beforehand was that I didn't think of these use-cases, rather than for any technical reason; this new method should not have any drawbacks save making the output slightly wider in a few cases. Compatibility with ls is also a big plus.
Fixes#104, and relates to #88 and #92.
This fixes a bug where extra sorting options (dirs first, reverse) were not applied when listing in long mode. In other words, fixes#105.
The bug occurred because the sorting function only took Files, but the details view uses File eggs that only contain Files. This commit changes the sorting function to accept anything that AsRefs to File, and impls that on both File and Egg so the same function works for both.
Thinking about it, it doesn't make sense to use an *external* time zone source when the program we want to compare it to, ls, uses the system one. So just use the system one.
Also, handle the case where the time zone data file can't be loaded by showing the files in UTC rather than falling over and quitting.
