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
Using --octal_permissions will insert another column before the existing
permissions where permissions are encoded using octal values as
requested in #316
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 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.
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.
Apparently I forgot to give the --time flag an argument, and this wasn’t actually covered by any of the xtests! Well, it’s tested now.
I’m not sure how to handle multiple --time arguments.
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.
