I read through every file and applied a couple of rustfmt suggestions. The brace placement and alignment of items on similar lines has been made consistent, even if neither are rustfmt's default style (a file has been put in place to enforce this). Other changes are:
• Alphabetical imports and modules
• Comma placement at the end of match blocks
• Use newlines and indentation judiciously
• Spaces around associated types
• Spaces after negations (it makes it more clear imho)
• Comment formatting
• Use early-returns and Optional `?` where appropriate
This commit makes changes to the way variables are referenced:
• Make types Copy when possible
• Make methods take `self` instead of `&self` where possible (trivially_copy_pass_by_ref)
• Remove unnecessary borrowing (needless_ref)
• Remove unnecessary cloning (clone_on_copy)
• Remove `ref` from match arms where possible (new Rust match ergonomics)
This commit uses Clippy to fix all the 'use_self' warnings. Using Self instead of the type name has been good Rust style for a while now, and it's become the style I'm used to seeing.
Using --octal_permissions will insert another column before the existing
permissions where permissions are encoded using octal values as
requested in #316
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”.
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.
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!
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.
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.
The old option descriptions were all written at different times, and needed some consistency. This makes everything consistent between the help text, README, man page, and shell completions, and fixes some mistakes made when writing them.
This also adds the missing options to the man page, fixing #175.
Now when you do `--sort time` instead of saying "unknown option --sort
time" it will say "unknown options '--sort time' (choices: name...)"
with all legal options.
This also adds the legal values to the default help text.
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.
