I'm tagging this as a "stable" 2.0 release because the 2.0-beta#
numbering will get confusing when I'm working on new features and fixes.
It's still only usable for people who can use the particular Zig version
that's required (0.9.0 currently) and it will certainly break on
different Zig versions. But once you have a working binary for a
supported arch, it's perfectly stable.
This used to be the default before 1.5, but for some reason the default
changed in 1.5 and 1.6. Changing it back now, because the graph really
is useful, and there's still enough space for the filename even in
smaller terminals.
Here is the new multi-page listing functionality I promised in
5db9c2aea1.
It may look very easy, but getting this to work right wasn't,
unfortunately.
When interrupinting the calculation process by pressing 'q' while
it's looping through a directory, or when a directory could be openend
but not chdir()'ed into, closedir() wasn't called.
Setting FF_BSEL after calling browse_init() causes two items to be
selected, as browse_init() makes sure something will be selected,
while calc_process() assumes nothing is, because the previously
selected item had just been deleted.
Hard link detection is now done in a separate pass on the in-memory tree,
and duplicates can be 'removed' and 're-added' on the fly. When making any
changes in the tree, all hard links are re-added before the operation and
removed again afterwards.
While this guarantees that all hard link information is correct, it does
have a few drawbacks. I can currently think of two:
1. It's not the most efficient way to do it, and may be quite slow on
large trees. Will have to do some benchmarks later to see whether
it is anything to be concerned about.
2. The first encountered item is considered as 'counted' and all items
encountered after that are considered as 'duplicate'. Because the
order in which we traverse the tree doesn't always have to be the
same, the items that will be considered as 'duplicate' can vary with
each deletion or re-calculation. This might cause confusion for
people who aren't aware of how hard links work.
