This was touched on in #209 where I got the docs wrong compared to the actual implementation, but after thinking about it, I’d like to switch it round. (The --sort=Name and --sort=name difference has also been switched.) See the big ol’ comment for my reasons.
Because this changes core functionality, it broke many, many tests. You can see that this doesn’t change the -star- tests because the shell, rather than exa, orders the globbed files.
I kept on forgetting which way round Sensitive and Insensitive went, so I named them after the effect they have.
I want to be very careful when doing the “--git and --tree don’t work together” one to not search for more Git repositories than I should. Being able to log when a repository is looked up and also switch that functionality on and off would help with that.
This commit gives IgnorePatterns a bunch of constructor methods that mean its option-parsing sister file doesn’t need to know that it’s a vec of glob patterns inside: it can work with anything that iterates over strings. Now, the options module doesn’t need to know about the glob crate.
This commit moves the definitions of Filter and DirAction from the options module to the fs module, but leaves the parts that actually have to do with option parsing alone.
Now, the options module shouldn’t define any types that get used elsewhere in the program: it only adds functionality to types that already exist.
This isn’t perfect, as a file’s type isn’t cached, so it gets recomputed for every comparison in the sort! We can’t go off the file’s `st_mode` flag because it’s not guaranteed to be in any order between systems.
The arguments passed to File’s constructor were different from the field names used — these might as well both be the same.
Also, move ext and filename to be File methods to save an import, and add tests.
Also also, by passing a PathBuf in to the constructor directly, we can save one (possibly two) instance/s where we pass in a reference to something we were going to lose ownership of anyway, only to have it basically cloned.
There was a problem when displaying . and .. in directory listings: their names would normalise to actual names! So instead of literally seeing `.`, you’d see the current directory’s name, inserted in sort order into the list of results. Obviously this is not what we want.
In unrelated news, putting `.` and `..` into the list of paths read from a directory just takes up more heap space for something that’s basically constant.
We can solve both these problems at once by moving the DotFilter to the files iterator in Dir, rather than at the Dir’s creation. Having the iterator know whether it should display `.` and `..` means it can emit those files first, and because it knows what those files really represent, it can override their file names to actually be those sequences of dots.
This is not a perfect solution: the main casualty is that a File can now be constructed with a name, some metadata, both, or neither. This is currently handled with a bunch of Options, and returns IOResult even without doing any IO operations.
But at least all the tests pass!
I originally thought that the entries . and .. were in *every* directory entry, and exa was already doing something to filter it out. And then... I could find no such code! Turns out, if we want those entries present, we have to insert them ourselves.
This was harder than expected. Because the file filter doesn’t have access to the parent directory path, it can’t “filter” the files vector by inserting the files at the beginning.
Instead, we do it at the iterator level. A directory can be scanned in three different ways depending on what sort of dotfiles, if any, are wanted. At this point, we already have access to the parent directory’s path, so we can just insert them manually. The enum got moved to the dir module because it’s used most there.
The problem here was that we were using `metadata.permissions().mode()`, which is capped at 0o777, rather than `metadata.mode()`, which exposes every bit. With this change, we can access the higher-order permission bits, and put them in the Permissions struct.
The three pieces of information for the leftmost details view column (file type, permissions, and whether xattrs are present) used to be gathered from separate sources and passed around separately before being displayed at the end. Now, file type and permissions are put into a struct, along with the xattrs boolean that’s still getting passed around all over the place but not quite as much.
This was all done because I wanted to be able to test permissions rendering, without having file type and xattrs dragged into the same function.
Override the size column for block and charater devices, so it shows the major and minor device IDs instead (which are in the Metadata struct somewhere).
This is what ls does when faced with a device.
Fixes#134, a bug that showed symlinks incorrectly as broken, but only when the file was listed directly on the command-line *and* the file was in a different directory to the one exa was being run in.
I’m not sure why the old code used `String::new()`, but it doesn’t seem to affect anything.
Because the link style and status are now both available to the function that picks the colour style, we can have it highlight broken links differently.
Fixes#131.
We already use MetadataExt and PermissionsExt, so it already requires a Unix system — there’s no point providing fallback implementations if it wouldn’t build on those systems anyway.
It's confusing, and `ls` doesn't do this either. We're not prepending
the current path to all of the directory entries, and the user is going
to interpret the symlink target as relative to the directory containing
the symlink.
Fixes#123. The code assumes that every File that has its link_target() method called would first have been checked to make sure it’s actually a link first. Unfortunately it also assumed that the only thing that can go wrong while following a link is if the file wasn’t a link, meaning it crashes when given a link it doesn’t have permission to follow.
This makes the file_target() method able to return either a file or path for displaying, as before, but also an IO error for when things go wrong.
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'.
