c475cccce4 Flip the new/old order, and add suggestion for -lt
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”.

a8bf990674 Tie value suggestions to their arguments
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.

36cf5df044 Add support for optional argument/flag with optional value
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.

43bbf00478 Show a warning when running ‘exa -ltr’
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.

0fefc78cbb Add more modified date aliases
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”.

dc45332d7b Implement file name colouring in {exa,ls}_colors
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.

45a807a14f Redo Git implementation to allow --git --recurse
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.

3d4ddf8af6 Group Git repositories by their workdir
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.

040dbb2414 Use a global Git cache
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.

504a0dd6b7 Stop collecting ls_colors into a hashmap
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.

bfb8a5a573 Extract trait above file name colours
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.

276d18cf7c Give block and character devices different colours
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.

d517e9e12b Split FileTypes into types and kinds
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.

9b24649d68 Reverse what knows how to render a cell
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.

57c647fee5 Default to sorting case-insensitively
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.

a5e177afe5 Now we can log OS error 95
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.

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.

dbebd60c4e Extract var_os and use the mock to test
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!

6b309d5cfc Make SizeFormat lenient, and add tests
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.

0b87392fd4 Decouple assert_eq! and assert_parses
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.

ff497b52e5 Be stricter in strict mode
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.

b5bcf22612 Merge remote-tracking branch origin/option-pars-ng
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.

9872eba821 Separate the matched flags from the free strings
Originally, both the matched flags and the list of free strings were returned from the parsing function and then passed around to every type that had a ‘deduce’ method. This worked, but the list of free strings was carried around with it, never used.

Now, only the flags are passed around. They’re in a new struct which has the methods the Matches had.

Both of Matches’s fields are now just data, and all of the methods on MatchedFlags don’t ignore any fields, so it’s more cohesive, at least I think that’s the word.

Building up the MatchedFlags is a bit more annoying though because the vector is now hidden behind a field.

2d1f462bfa Switch to the new options parser
This commit removes the dependency on the ‘getopts’ crate entirely, and re-writes all its uses to use the new options parser instead.

As expected there are casualties galore:

- We now need to collect the options into a vector at the start, so we can use references to them, knowing they’ll be stored *somewhere*.
- Because OsString isn’t Display, its Debug impl gets used instead. (This is hopefully temporary)
- Options that take values (such as ‘sort’ or ‘time-style’) now parse those values with ‘to_string_lossy’. The ‘lossy’ part means “I’m at a loss for what to do here”
- Error messages got a lot worse, but “--tree --all --all” is now a special case of error rather than just another Misfire::Useless.
- Some tests had to be re-written to deal with the fact that the parser works with references.
- ParseError loses its lifetime and owns its contents, to avoid having to attach <'a> to Misfire.
- The parser now takes an iterator instead of a slice.
- OsStrings can’t be ‘match’ patterns, so the code devolves to using long Eq chains instead.
- Make a change to the xtest that assumed an input argument with invalid UTF-8 in was always an error to stderr, when that now in fact works!
- Fix a bug in Vagrant where ‘exa’ and ‘rexa’ didn’t properly escape filenames with spaces in.

d93e168b4d Move Environment to a table’s Options
This commit moves the Environment field from the Table to its Options, and properly gets rid of the name ‘columns’ from the last commit.

Having it in the Options is important, because it means it can be generated from some command-line options. Also, it reduces the number of arguments that need to be passed to Table::new; there would have been 4 with the inclusion of the Environment, but by moving some of the code into the function, we can avoid this (and any further arguments).

The views have been renamed to be the Optionses of their module; now the options for the Table — Columns — has followed suit.

This works out, because the table module depended on everything in the columns module. It opens the door for other only-table-specific things to be included.

The casualty was that by making it non-Clone and non-PartialEq, a bunch of other #[derive]-d types had to have their derivions removed too.

4c41141cb9 Give Tree its own iterator
The goal of this part of the refactoring, if you wondered, is to make it so only the tree module is aware that it needs ‘depth’ and ‘last’ values to draw the tree.

As far as the details module is concerned, it should just be doing something to produce TreeParams values which it later consumes; that’s it.

This change should make it easier to have tables that may or may not have a tree in them.

97236128ea Only get an Env if one’s being used, also mutexes
This commit ties a table’s Environment to the fact that it contains columns.

Previously, the Details view would get its Environment, and then use those fields to actually display the details in the table: except for the case where we’re only displaying a tree, when it would just be ignored, instead.

This was caused by the “no columns” case using a Vec of no Columns behind the scenes, rather than disabling the table entirely; much like how a tap isn’t a zero-length swipe, the code should have been updated to reflect this. Now, the Environment is only created if it’s going to be used.

Also, fix a double-mutex-lock: the mutable Table had to be accessed under a lock, but the table contained a UsersCache, which *also* had to be accessed under a lock. This was changed so that the table is only updated *after* the threads have all been joined, so there’s no need for any lock at all. May fix #141, but not sure.

fc60838ff3 Extract table from details and grid_details
This commit extracts the common table element from the details and grid_details modules, and makes it its own reusable thing.

- A Table no longer holds the values it’s rendering; it just holds a continually-updated version of the maximum widths for each column. This means that all of the resulting values that turn into Rows — which here are either files, or file eggs — need to be stored *somewhere*, and that somewhere is a secondary vector that gets passed around and modified alongside the Table.
- Likewise, all the mutable methods that were on Table that added a Row now *return* the row that would have been added, hoping that the row does get stored somewhere. (It does, don’t worry.)
- Because rendering with mock users is tested in the user-field-rendering module, we don’t need to bother threading different types of U through the Environment, so now it’s just been specialised to UsersCache.
- Accidentally speed up printing a table by not buffering its entire output first when not necessary.

340bccbcfc Forbid --tree --all --all

dd8bff083f Override the names of . and ..
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!

20793ce7f4 Implement . and .. by inserting them maually
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.

65d94636d7 Remove filter and dir_action from Details
These two fields were originally needed to determine how to recurse when using tree view.

However, as there was no distinction between the “options parsed from the command-line” Details and the “values needed to render a table” Details, these had to be threaded through the options parser as a special-case to end up in the right struct.

No more! Because there are separate structs for options and rendering, we can just add them in later.

14144e2ad3 Create Render structs from views
Instead of having render methods on the types that are now called Options, create new Render structs (one per view) and execute them. This means that it’s easier to extract methods from them — some of them are pretty long.

Also, remove the GridDetails struct, which got consumed by Mode (mostly)

By introducing another indirection between the structs that command-line options get parsed into and the structs that get rendered, it should be easier to refactor that horrible function in view.rs.

aea0035f94 Move Colour and Classify to the View
All four view types — lines, grid, details, and grid-details — held their own colours and classify flags.

This didn’t make any sense for the grid-details view, which had to pick which one to use: the values were in there twice.

It also gave the Table in the details view access to more information than it really should have had.

Now, those two flags are returned separately from the view “mode”, which is the new term for one of those four things.

a2901c63cf Render higher permission bits
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.

f9f7ad2230 Read setuid/setgid/sticky bits
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.

957c1925b1 PermissionsPlus holds the leftmost column values
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.

ba1c8c650f Fix bug where paths took up twice as much space
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.

a53c268c54 Measure, rather than calculating, cell widths
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.

74358c188a Properly handle errors when following a 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.

a7e3456b0d Only engage the view when there are files to show
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”

110a1c716b Convert exa into a library
This commit removes the 'main' function present in main.rs, renames it to exa.rs, and puts the 'main' function in its own binary. This, I think, makes it more clear how the program works and where the main entry point is.

Librarification also means that we can start testing as a whole. Two tests have been added that test everything, passing in raw command-line arguments then comparing against the binary coloured text that gets produced.

Casualties include having to specifically mark some code blocks in documentation as 'tests', as rustdoc kept on trying to execute my ANSI art.

This will mean that we can test exa's output as a whole, without having to rely on process or IO or anything like that.

e9e1161cec Split up the options module
The original options was becoming a bit unwieldy, and would have been even more so if I added the same amount of comments. So this commit splits it up.

There's no extra hiding going on here, or rearranging things within the module: (almost) everything now has to be marked 'pub' to let other sub-modules in the new options module to see it.

b44ae1b56b Remove pointless OptionSet trait
The trait was only used internally to the options module, so it doesn't actually need to be exist or implemented on anything! We can just impl them directly on the types and have those methods be local to the module.

fae0f3874e Create info module with business logic routines
Currently these routines number two: file type checking based on a file's name, and source file checking, also based on the file's name.

efa372cb3b Source file rearrangements
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'.

b65043d6d9 Update raw libc types for Rust 1.8.0
Fixes #108. MetadataExt now returns direct numeric types rather than platform-specific ones, so we need to adjust the functions that use these to have the new types. I've just aliased the types to specific ones so the rest of the code remains the same (file.rs is the only place that uses this)

The RFC that changed this is here: https://github.com/rust-lang/rust/pull/31551

9b87ef1da2 Print the parent path for passed-in files
This commit changes all the views to accommodate printing each path's prefix, if it has one.

Previously, each file was stripped of its ancestry, leaving only its file name to be displayed. So running "exa /usr/bin/*" would display only filenames, while running "ls /usr/bin/*" would display each file prefixed with "/usr/bin/". But running "ls /usr/bin/" -- without the glob -- would run ls on just the directory, printing out the file names with no prefix or anything.

This functionality turned out to be useful in quite a few situations: firstly, if the user passes in files from different directories, it would be hard to tell where they came from (especially if they have the same name, such as find | xargs). Secondly, this also applied when following symlinks, making it unclear exactly which file a symlink would be pointing to.

The reason that it did it this way beforehand was that I didn't think of these use-cases, rather than for any technical reason; this new method should not have any drawbacks save making the output slightly wider in a few cases. Compatibility with ls is also a big plus.

Fixes #104, and relates to #88 and #92.

f6c5c89f55 Always sort files the same way
This fixes a bug where extra sorting options (dirs first, reverse) were not applied when listing in long mode. In other words, fixes #105.

The bug occurred because the sorting function only took Files, but the details view uses File eggs that only contain Files. This commit changes the sorting function to accept anything that AsRefs to File, and impls that on both File and Egg so the same function works for both.
