Fixes#134, a bug that showed symlinks incorrectly as broken, but only when the file was listed directly on the command-line *and* the file was in a different directory to the one exa was being run in.
I’m not sure why the old code used `String::new()`, but it doesn’t seem to affect anything.
* `$BASHDIR` and `$FISHDIR` had incorrect paths
* Fix `$FEATURES` to actually work
* Add `-f` to `rm` invocations to quiet missing file errors
* Just use `man` to preview the manpage
* Fix (again) `make` not rebuilding
* Add `make help` to view all of the commands and variables
Because the link style and status are now both available to the function that picks the colour style, we can have it highlight broken links differently.
Fixes#131.
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.
We already use MetadataExt and PermissionsExt, so it already requires a Unix system — there’s no point providing fallback implementations if it wouldn’t build on those systems anyway.
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.
This is slighly slower for the case where escaped characters are displayed in the same colour as the displayable characters, which happens when listing a directory’s name when recursing. Optimise this, yeah?
This turns `file` into `self.file` and `colours` into `self.colours`, but it means we don’t need to pass arguments everywhere, which will be more of a problem the more functions there are.
Most of the code has just been indented.
Rather than the *entire* file name.
The current method is extremely inefficient, but having control characters in file names is also extremely uncommon; it’s something that should be fixed, only eventually.
