From 4ddb608563d985060d69594d1004550a680ae3bd Mon Sep 17 00:00:00 2001 From: Christian Duerr Date: Wed, 31 Aug 2022 22:48:38 +0000 Subject: Add IPC config subcommand This patch adds a new mechanism for changing configuration options without editing the configuration file, by sending options to running instances through `alacritty msg`. Each window will load Alacritty's configuration file by default and then accept IPC messages for config updates using the `alacritty msg config` subcommand. By default all windows will be updated, individual windows can be addressed using `alacritty msg config --window-id "$ALACRITTY_WINDOW_ID"`. Each option will replace the config's current value and cannot be reset until Alacritty is restarted or the option is overwritten with a new value. Configuration options are passed in the format `field.subfield=value`, where `value` is interpreted as yaml.
