* Change icon for gradle files to Java
Gradle files are for the whole Java ecosystem. Not just Android.
* Change the icon for jar & java to
Other java related files (class, jad, war) already use this.
The rationale here is that there's more of a background colour than the foreground colour when painting text, and having a gap of no background colour in between the icon and the file name looks weird.
Fixes GH-561.
exa now bases the icon style for a file on its file name and kind in all cases, rather than just on its file name. This means that directories and symlinks have the correctly-coloured icon.
It also only takes the foreground colour into account while styling the icon, to make sure they're not bold or underlined.
Fixes GH-528.
This commit makes adding icons to file names something that the file name renderer does, rather than something that each individual view does. This is now possible thanks to the previous commit a1869f2, which moved the option to do this into the same module. The repeated code has been removed.
It happens to fix a bug where the width of each column was being incorrectly calculated for the grid-details view, making lines slightly too long for the terminal because the icon wasn't being taken into account.
This commit significantly refactors the way that options are parsed. It introduces the Theme type which contains both styling and extension configuration, converts the option-parsing process into a being a pure function, and removes some rather gnarly old code.
The main purpose of the refactoring is to fix GH-318, "Tests fail when not connected to a terminal". Even though exa was compiling fine on my machine and on Travis, it was failing for automated build scripts. This was because of what the option-parsing code was trying to accomplish: it wasn't just providing a struct of the user's settings, it was also checking the terminal, providing a View directly.
This has been changed so that the options module now _only_ looks at the command-line arguments and environment variables. Instead of returning a View, it returns the user's _preference_, and it's then up to the 'main' module to examine the terminal width and figure out if the view is doable, downgrading it if necessary.
The code that used to determine the view was horrible and I'm pleased it can be cut out. Also, the terminal width used to be in a lazy_static because it was queried multiple times, and now it's not in one because it's only queried once, which is a good sign for things going in the right direction.
There are also some naming and organisational changes around themes. The blanket terms "Colours" and "Styles" have been yeeted in favour of "Theme", which handles both extensions and UI colours. The FileStyle struct has been replaced with file_name::Options, making it similar to the views in how it has an Options struct and a Render struct.
Finally, eight unit tests have been removed because they turned out to be redundant (testing --colour and --color) after examining the tangled code, and the default theme has been put in its own file in preparation for more themes.
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.
