This allows printing directory trees without any files, only
showing the structure.
I haven't decided on a letter for the short option.
Implements #401
This improves performance by a factor of at least 2 in large --tree workloads by avoiding the repeated creation/destruction of the pool and containing threads.
Cycling pools also encountered lots lock contention, which accounted for most of the time saved by reusing a single pool.
Add two new sort options `.name` and `.Name` which with ignore a leading
`.` if present on the file name before sorting according to `name` and
`Name`.
This new sort is convenient if you want to list hidden and unhidden
files sorted together.
Fixes#288, but more-or-less as a side-effect.
The “mi” key in LS_COLORS was meant to be used for a missing link path, but it wasn’t really used like that. There was also a bug where control characters in a broken symlink’s path were assumed to be underlined, because that’s what happened in the default colour scheme, but this assumption doesn’t hold when colours were disabled.
The solution to these was not to introduce another configurable colour code, but to start using _overlays_ to alter a bunch of colours at once. The “mi” code will have to be added back later.
This doesn’t *completely* work: it seems to have trouble with ignored paths beginning with slashes, possibly amongst others. Also, .gitignore scanning could be made more efficient.
I changed my mind about which way round sorting by “newest” or by “oldest” should actually go. If you’re listing a large directory, you see the last lines of the output first, so these files should be the ones with the largest whatever the sort field is. It’s about sorting *last*, not sorting *first*. Sorting by size wouldn’t say “sorts smallest files first”, it would say “sorts largest files last”. Right?
Also, add a new suggestion that warns against “ls -lt”.
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.
TakesValue::Optional introduced which allows for an optional flag with
an optional value (equivalent to getopts' optflagopt mode).
Can be used where a default value for a modifier could exist, but the
user might prefer to override.
Will be used to implement #284, permitting --time to default to "sort by
modification date" for compatibility with GNU/posix ls but keeping
support for exa's previous behavior.
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.
No new features here, just some restructuring. Mode::GridDetails was nice and elegant with those two fields, but now there’s a grid-details-only option the elegance has gone out the window.
Yeah, I forgot what I was meant to be doing half-way through.
This also adds the row_threshold field, which disables the view unless there will be more than the given number of rows. Getting the row count required upgrading term_grid to a version that has that function added.
Previously the iterator went all the way through `2..`, and not only would that take a very long time, but at the end it wouldn’t even print anything. Now the grid-details view turns into a lines view when it’s hit its limit.
exa now ignores errors when checking for extended attributes when the user didn’t explicitly demand that they be checked. If a file does have xattrs, it’ll still display the @ in the permissions column; errors will now just cause the @ to be hidden instead.
This changed a lot of the xtests, which were displaying the error message in a few situations. Those tests have gained @-suffixed companions so the actual error messages can still be tested.
Fixes#178 (finally)
It’s a good test to be able to switch strict mode on in run.sh and not have it break anything! Now, the EXA_STRICT environment variable will toggle it on. We can even switch it off and see that it doesn’t error.
Some of the deduce functions used to just blatantly call std::env::var_os and not care, introducing global state into a module that was otherwise nice and functional and self-contained. (Well, almost. There’s still terminal width.)
Anyway, this made it hard to test, because we couldn’t test it fully with this global dependency in place. It *is* possible to work around this by actually setting the environment variables in the tests, but this way is more self-documenting.
With this in place, we can start to unit test things like deriving the view by passing in what the $COLUMNS environment variable should be, and that’s one of the first things checked.
src/options/mod.rs *almost* has all its tests moved to where they should be!
Sometimes, the type in the Ok part of the Result wouldn’t implement PartialEq, so the first macro (which uses assert_eq) won’t work. In these cases, this new macro can be used instead, which just unwraps the Err’s contents. In other cases, it can shave off a ) at the end of a few lines.
The table Options struct is roughly half runtime configuration and half flags to select which columns to display The column fields might as well be in their own struct, and now that the ‘for_dir’ function doesn’t use SizeFormat, it can be moved to Columns.
Way in the past, the size format was the only variable column; the others were all fixed. Now there are many configurable columns and this field was still hanging around. The code that does the rendering just gets the size format as an argument, and now it works the same way as the TimeFormat.
This changes the SizeFormat option parser from its old, strict-by-default behaviour (where passing both --bytes and --binary would be an error) to the new, use-the-last-argument behaviour (where passing --bytes --binary would use --binary because it came later).
Doing this meant adding functionality to Matches so that it could return *which* argument matched. Previously, the order of --bytes and --binary didn’t matter, because they couldn’t both be present, but now it does.
The assert_parses function was problematic because it insisted on using assert_eq! to check its contents. This won’t work for any type we want to test that doesn’t implement PartialEq, such as TimeFormat, which holds references to years and date strings and other such.
To go about fixing this, the first step is to change that function so it only does the initial processing, rather than the assertion, which is now done outside of it in the test macros instead.
Now the code actually starts to use the Strictness flag that was added in the earlier commit! Well, the *code* doesn’t, but the tests do: the macros that create the test cases now have a parameter for which tests they should run. It’s usually ‘Both’ for both strict mode and default mode, but can be specified to only run in one, for when the results differ (usually when options override one another)
The downside to strict mode is that, now, *any* call to `matches.has` or `matches.get` could fail, because an option could have been specified twice, and this is the place where those are checked for. This makes the code a little less ergonomic in places, but that’s what the ? operator is for. The only place this has really had an effect is in `Classify::deduce`, which used to just return a boolean but can now fail.
In order to more thoroughly test the mode, some of the older parts of the code can now act more strict. For example, `TerminalColours::deduce` will now use the last-given option rather than searching for “colours” before “colors”.
Help and Version continue doing their own thing.
The value is ignored, but this broke quite a lot of tests that assumed MatchedFlags had only one field.
Parsing tests have to have OsStr flags because I couldn’t get that part working right, but in general, some tests now re-use common functionality too.
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 merges in exa’s own new options parser, which has the following features:
- You can specify an option twice and it’ll use the second one, making aliases usable for defaults (fixes#144)
- Lets arguments be specified more than once (fixes#125)
Strict mode is not done yet; I just wanted to merge this in because it’s been a while, and there’s work that needs to be done on master so I don’t want them drifting apart any further.
It’s likely that you’ll find cases where multiple arguments doesn’t work or where the wrong value is being used. There aren’t tests for *everything* yet, and it still uses global environment variables.
# Conflicts:
# src/options/view.rs
The term_size crate introduced in #237 did things *slightly* differently than exa: it tried to get the terminal width of stdout, stderr, and stdin. This broke some tests that only redirected stdout.
