From 051df3cfe8ed7d113197636f860edea14f283037 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Thu, 18 Jun 2020 20:49:57 +0000 Subject: [PATCH] wt-status: show sparse checkout status as well Some of the early feedback of folks trying out sparse-checkouts at $dayjob is that sparse checkouts can sometimes be disorienting; users can forget that they had a sparse-checkout and then wonder where files went. Add some output to 'git status' in the form of a simple line that states: You are in a sparse checkout with 35% of files present. where, obviously, the exact figure changes depending on what percentage of files from the index do not have the SKIP_WORKTREE bit set.
