From 7bffca95ea1ca4f55663374ea9b929b9df5be04b Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Thu, 21 Nov 2019 22:04:37 +0000 Subject: sparse-checkout: add '--stdin' option to set subcommand The 'git sparse-checkout set' subcommand takes a list of patterns and places them in the sparse-checkout file. Then, it updates the working directory to match those patterns. For a large list of patterns, the command-line call can get very cumbersome. Add a '--stdin' option to instead read patterns over standard in.
