Unlike the others, setuid/setgid/sticky get merged with user/group/other execute in the rendered Permissions cell. So there had to be a bit of code change done to make sure that none of the bits clashed.
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.
On the plus side, this removes some imports from details, and makes the file shorter. On the minus side, the ‘render timestamp’ function has a hell of a signature.
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.
A field can now render itself using colours and a users reference, rather than a Table doing the rendering. This way, only the relevant fields in the Environment can be made available to the render function, and the test code loses some lines.
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.
By parsing OsStrings rather than Strings, it’s the getopts crate that’s doing the UTF-8 checking rather than us, so if one of them isn’t valid, it’ll just fail to parse rather than crash exa.
Also, save a few allocations here and there.
This makes it possible to use them in scripts. Also, I couldn’t find any other program returned a different error code! So it’s being changed to 0.
Fixed#180.
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.
The old option descriptions were all written at different times, and needed some consistency. This makes everything consistent between the help text, README, man page, and shell completions, and fixes some mistakes made when writing them.
This also adds the missing options to the man page, fixing #175.
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.
For some reason, the code that calculated the width of a cell with a path in counted the width of the path twice: once from the ANSIStrings containing it, and once more added on afterwards. This meant that the grid view thought that columns were wider than they really were, meaning fewer could be fit into a grid.
Doing this meant that the escaping functionality got used in three places, so it was extracted into a generalised function in its own module.
This is slighly slower for the case where escaped characters are displayed in the same colour as the displayable characters, which happens when listing a directory’s name when recursing. Optimise this, yeah?
This turns `file` into `self.file` and `colours` into `self.colours`, but it means we don’t need to pass arguments everywhere, which will be more of a problem the more functions there are.
Most of the code has just been indented.
Rather than the *entire* file name.
The current method is extremely inefficient, but having control characters in file names is also extremely uncommon; it’s something that should be fixed, only eventually.
exa deals with cells and widths a lot: the items in a grid need to be aligned according to their *contents’* widths, rather than the length of their strings, which often included ANSI escape characters. As an optimisation, it used to calculate this separately based on the filename, and dealing with any extra characters (such as the classify ones) in that function too.
Recently, though, file names have become a lot more complicated. Classification added zero to one extra characters, and now with escaped control characters in file names, it’s not so easy to calculate the display width of a filename.
This commit removes the function that calculated the width, in favour of building the output string (it’s going to be displayed anyway) and just getting the width of what it displays instead.
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.
It’s the only file where its path is the same as its file name, and has been the source of numerous bugs in the past… this special-case isn’t very clean, but it works.
This adds an option (always on at the moment) to use a colour scale of green to yellow to orange for the file size field instead of always green. See #65.
This makes the Colours value pick a colour based on the size of the file, instead of necessarily having them all green. (They are all green for now, though.)
See #97 and recently #130 too.
This allows the user to pass in options such as "--ignore '*.pyc'" to not list any files ending in '.pyc' in the output. It uses the Rust glob crate and currently does a simple split on pipe, without any escaping, so it’s not really *complete*, but is at least something.
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 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”
