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.

4c16f50565 Fix an error being displayed weirdly
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.

6740faa781 env vars should be referenced, not copied
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.

da00e2fda2 Thread the row threshold through grid_details
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.

adaa36e1c5 Integrate strict mode, use it to test file sizes
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.

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!

f389943bf1 New macro for testing deduce errors
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.

6755ee6ae9 Extract table columns into a struct
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.

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.

00379cce63 Thread Strictness through the parser
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.

c1e206669e Give IgnorePatterns a better interface
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.

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.

4289f4d27e Specify that we need the width of stdout
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.

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.

82e6fa2352 Add tests for dir_option
One of the previous tests started to fail, because it was working when it shouldn’t have! It worked up until now because I forgot to flag --level as taking an argument, and “--level 4” still worked with 4 as a filename. So there’s now an early check for that functionality that got lost somewhere.

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.

5b1966d261 Move filter and dir_action from options to fs
This commit moves the definitions of Filter and DirAction from the options module to the fs module, but leaves the parts that actually have to do with option parsing alone.

Now, the options module shouldn’t define any types that get used elsewhere in the program: it only adds functionality to types that already exist.
