We upgraded our minimum Go version to 1.21 in commit 57ac9c2189458a7f0e63c2e9cac8334694a3d545. We can now replace our `utils.Min` and `utils.Max` functions with the built-in `min` and `max`. Reference: https://go.dev/ref/spec#Min_and_max Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>
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.
