From 4bf0c06c7169da61de489544207a7659ef31029f Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 11 Feb 2020 15:02:22 +0000 Subject: sparse-checkout: extract pattern update from 'set' subcommand In anticipation of adding "add" and "remove" subcommands to the sparse-checkout builtin, extract a modify_pattern_list() method from the sparse_checkout_set() method. This command will read input from the command-line or stdin to construct a set of patterns, then modify the existing sparse-checkout patterns after a successful update of the working directory. Currently, the only way to modify the patterns is to replace all of the patterns. This will be extended in a later update.
