From: Michal Nazarewicz <min...@mina86.com> This commit changes enable and disable commands so that they accept not only output number but also its name. This way, one does not need to remember the number of the output but instead use its name. It also makes user command work even if number and order of outputs in configuration file changes (as long as names stay the same). --- src/command.c | 36 ++++++++++++++++++++++++++++++------ src/main.c | 4 ++-- 2 files changed, 32 insertions(+), 8 deletions(-)
