This adds range select ability in two ways: 1) Sticky: like what we already have with the staging view i.e. press v then use arrow keys 2) Non-sticky: where you just use shift+up/down to expand the range The state machine works like this: (no range, press 'v') -> sticky range (no range, press arrow) -> no range (no range, press shift+arrow) -> nonsticky range (sticky range, press 'v') -> no range (sticky range, press arrow) -> sticky range (sticky range, press shift+arrow) -> nonsticky range (nonsticky range, press 'v') -> no range (nonsticky range, press arrow) -> no range (nonsticky range, press shift+arrow) -> nonsticky range
FileTree Package
This package handles the representation of file trees. There are two ways to render files: one is to render them flat, so something like this:
dir1/file1
dir1/file2
file3
And the other is to render them as a tree
dir1/
file1
file2
file3
Internally we represent each of the above as a tree, but with the flat approach there's just a single root node and every path is a direct child of that root. Viewing in 'tree' mode (as opposed to 'flat' mode) allows for collapsing and expanding directories, and lets you perform actions on directories e.g. staging a whole directory. But it takes up more vertical space and sometimes you just want to have a flat view where you can go flick through your files one by one to see the diff.
This package is not concerned about rendering the tree: only representing its internal state.
