This commit changes the definition of Arg so that it knows about which values it can accept, and can display them in the help text. They were already being shown in the help text, but they were passed in separately, so one argument could show two different sets of options if it wanted. Now, the argument itself knows whether there are suggestions, so it doesn’t have to be passed in separately.
This means we can use it for other things, including listing choices when an option is missed out, without having to repeat the list.
With Misfire::BadArgument now only having two fields, it’s not worth using a constructor function anymore.
Raised in #243 and #284. exa isn’t able to override the -t option like this, so the least it can do is detect that case (which is going to be an error case anyway) and show a suggestion.
I don’t really see the modified date as the *modified* date, rather just the *date* field, because it’s the date field I refer to like 99.9% of the time. So now it has aliases to match.
Also are included are aliases for the reverse order, because I’d rather write “new” than “the reverse of old”.
It said “(Choices: (choices: this, that, other))” instead of “(choices: this, that, other)”. Also improve the same error elsewhere: options more have ‘settings’ than ‘values’.
This commit adds to the parsing of the LS_COLORS and EXA_COLORS variables so that non-two-letter codes (keys other than things like ‘di’ or ‘ln’ or ‘ex’) will be treated as file name globs, and get used to colour files accordingly.
Fixes#116 for good.
This is more annoying than it should be because it has to work with Styles rather than with strings, which means parsing them, and parsing is always tricky business.
This is all a big commit because it took a lot more work than I thought it would! The commit basically moves Git repositories from being per-directory to living for the whole life of the program. This allows for several directories in the same repository to be listed in the same invocation; before, it would try to rediscover the repository each time! This is why two of the tests “broke”: it suddenly started working with --recurse.
The Dir type does now not use Git at all; because a Dir doesn’t have a Git, then a File doesn’t have one either, so the Git cache gets passed to the render functions which will put them in the Table to render them.
This uses the Git module’s newfound powers of getting actual GitRepo values from a factory to cache repositories a bit more. Now, when querying two directories under the same repository, it’ll open both, see that they have the same workdir, and only use the first one.
This commit adds a cache for Git repositories based on the path being queried.
Its only immediate effect is that when you query the same directory twice (such as /testcases/git /testcases/git), it won’t need to check that the second one is a Git directory the second time. So, a minuscule optimisation for something you’d never do anyway? Wrong! It’s going to let us combine multiple entries over the same repository later, letting us use --tree and --recurse, because now Git scanning is behind a factory.
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.
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.
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.
Just because the type that gets used right now is Copy and Clone doesn’t mean that when we pass mock ones in for tests they’ll be those two as well. So we have to go through and add &s everywhere.
