This adds support for the EXA_COLORS environment variable, and defines a bunch of exa-specific two-letter codes that I pretty much made up arbitrarily that control parts of the interface.
Fixes#160, which I didn’t expect to actually fix this release cycle, but it unexpectedly became easy to do!
LSColors used to be built up from an iterator, and then queried later. But because the resulting HashMap gets queried in serial anyway, we might as well pass in a callback instead, saving the allocation.
This is also technically a little faster because styles that don’t map to anything (like `zz`) are no longer parsed.
This commit meddles about with both the Colours and the FileExtensions.
Even though all the renderable fields were turned into traits, the FileName struct kept on accessing fields directly on the Colours value instead of calling methods on it. It also did the usual amount of colour misappropriation (such as ‘punctuation’ instead of specifying ‘normal_arrow’)
In preparation for when custom file colours are configurable (any day now), the colourise-file-by-kind functionality (links, sockets, or directories) was separated from the colourise-file-by-name functionality (images, videos, archives). The FileStyle struct already allowed for both to be separate; it was only changed so that a type other than FileExtensions could be used instead, as long as it implements the FileColours trait. (I feel like I should re-visit the naming of all these at some point in the future)
The decision to separate the two means that FileExtensions is the one assigning the colours, rather than going through the fields on a Colours value, which have all been removed. This is why a bunch of arbitrary Styles now exist in filetype.rs.
Because the decision on which colourise-file-by-name code to use (currently just the standard extensions, or nothing if we aren’t colourising) is now determined by the Colours type (instead of being derived), it’s possible to get it wrong. And wrong it was! There was a bug where file names were colourised even though the rest of the --long output wasn’t, and this wasn’t caught by the xtests. It is now.
This branch went part of the way towards supporting LS_COLORS in exa. If the variable is set, exa will style certain file kinds, such as sockets or directories or links, according to the style that corresponds with the relevant two-letter code. It doesn’t work with globs for files or extensions yet. That’s coming soon. See #116
There are now two device colours instead of one. Even though they’re both set to the same style for the default colour set, LS_COLORS allows the two to look different, so exa has to support it too.
It’s probably a good idea to support it anyway.
This separates the colours to give to files with different filesystem types (directories, links, sockets) from files with different names or extensions (images, videos, archives).
I’m not 100% sure I’ve got the terms “kind” and “type” the right way round, but whatever.
This was done because colouring files based on their name is going to be handled differently and extensibly from colouring files based on what the filesystem thinks.
This commit adds many traits, all named ‘Colours’, to the code. Each one asks for a colour needed to render a cell: the number of links asks for colours for the number and the multi-link-file special case; the file size asks for number, unit, punctuation, and device ID colours, or it can do a scale with its own colours, however it wants.
This is a step towards LS_COLORS compatibility, believe it or not. If a text cell in a column doesn’t depend on Colours to render itself, then the source of the colours is open-ended.
I am glad to have not needed any test changes here.
Now, the Vagrant VM uses my patched version of git2-rs, which has a modified build.rs file in libgit2-sys, which blocks libhttp_parser from being linked. As you can see by the comment, I’m not a fan of the fix, but at least it works, right?
See #194, and also #255.
Every time I had to build exa, I copied the files manually and checked to make sure they all had the same name. There’s now a script that does all that stuff for me, so I don’t need to remember to do it anymore.
It also does some things that weren’t being done before, including stripping the binary and listing its linked dependencies to we can tell if something like libhttp_parser has slipped in there (see #194)
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.
The Debug impl was being used instead of the Display one. Also, remove the full stops from the ends of all the error messages because I’ve decided it looks weird.
The error in #178 was being hidden from output most of the time, and because exa isn’t a GUI program, there’s nowhere it can really dump log output like this. Now that users can opt in with the EXA_DEBUG variable, there is a place it can go.
Also stop the ERROR log level being printed by default.
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.
