When trying to `require` a gem running in an unlinked directory, an exception is
thrown because `Dir.pwd` is called (see rubygems/rubygems#3087).
Until the fix lands in an official release, we monkey patch `Dir.pwd` to return
'/' if a `Errno::ENOENT` exception is raised while loading the colorls gem.
This should work for all Unixes. On Windows, this error cannot happen since you
cannot unlink a directory which is still in use by a process.
Fixes#351.
On Unix systems the encoding of file names is specified by the user via the
locale settings.
In order to avoid encoding problems simply read file names in ASCII 8 bit
encoding and try to convert to the external encoding while replacing undefined
characters.
Also, does not show an icon if the external encoding does not support it and
shows a `=` instead of a check mark for git status.
Fixes#352.
git does not report any status for empty directories, and it also does not
report any status for directories without any modified, untracked or ignored
files.
To correctly show the status, we need to check whether the directory is empty if
git did not report any status codes. When empty, show it as "not interesting",
otherwise the "no changes" green check mark is shown.
Note, I am specifically not using the untracked marker, as that would mean there
is some interesting file inside the directory which could be added.
Fixes#334.

This fixes the misalignment of files in a long listing when some files have a
different number of characters in the links column.
Instead of iterating three times over the @contents array, in order to compute
the sizes of the variant columns, use a single loop to compute the maximum size
for each column in a one pass.
* add and wire up `VerticalLayout` which is now the default
* adapt flags spec to use single-column layout for testing sort order
since the output is hard to verify when in vertical format
Fixes#189.
* add `Layout` base class which contains the base (binary) algorithm
for finding the maximum amount of columns fitting the given limit
* add `HorizontalLayout` and use it in `Core`
* add `SingleColumnLayout` and use it in `Core`
The git status is only computed for the given directory and is stored as
a Hash mapping relative paths to their mode string.
For a directory, the git status is comprised of all the statuses of its files
itself and all its sub directories.
The current directory's prefix is just an empty string matching all files inside
the `@git_status` Hash.
Asking for the status of the parent directory is pointless, we do not compute it
(yet).
* make `-h` an alias for `--human-readable`
* both options are simply ignored when used with an argument or another option
* running `colorls -h` still shows the help text since just as before
Using the `--show-prefix` option for `git ref-parse` simplifies determining the
status for the child items.
Previsouly, `File.realdirpath` was used to determine an absolute path, but this
method returns a path without symlinks. This caused status to be reported about
the link target instead of the symlink.
It reached EOL on 20th Jun 2018 and no longer receives patches.
* set required Ruby version to >= 2.3 in spec file
* set rubocop's TargetRubyVersion to 2.3 and fix all the offenses
Both are also supported by GNU ls, although currently not all formats are
supported.
This change lays ground for implementing column based formatting and also
supports using a pager with colorls keeping the formatting intact:
`colorls --color -x | less --tabs=4 -RFX`
This option works the same as for GNU ls, although if not specified colorization
is on by default (the `auto` mode).
Using `--color` is equivalent to `--color=always`.
