From 3e03eb3a017d144137dbe6591891f3a51a61dea0 Mon Sep 17 00:00:00 2001 From: Kenny Levinsen Date: Sat, 16 Mar 2024 00:48:56 +0100 Subject: [PATCH] config/output: Introduce apply_output_configs Introduce apply_output_configs, which applies the specified matched output configs as a single backend commit. Reimplement apply_output_config_to_outputs using apply_output_configs. --- include/sway/config.h | 11 ++++ sway/config/output.c | 148 +++++++++++++++++++++++++++++++++++------- 2 files changed, 135 insertions(+), 24 deletions(-) diff --git a/include/sway/config.h b/include/sway/config.h index f9da1967..d23fe578 100644 --- a/include/sway/config.h +++ b/include/sway/config.h @@ -291,6 +291,14 @@ struct output_config { char *background_fallback; }; +/** + * An output config pre-matched to an output + */ +struct matched_output_config { + struct sway_output *output; + struct output_config *config; +}; + /** * Stores size of gaps for each side */ @@ -684,6 +692,9 @@ void merge_output_config(struct output_config *dst, struct output_config *src); bool apply_output_config(struct output_config *oc, struct sway_output *output); +bool apply_output_configs(struct matched_output_config *configs, + size_t configs_len, bool test_only); + bool test_output_config(struct output_config *oc, struct sway_output *output); struct output_config *store_output_config(struct output_config *oc); diff --git a/sway/config/output.c b/sway/config/output.c index fd1d6e3c..de9515e2 100644 --- a/sway/config/output.c +++ b/sway/config/output.c @@ -9,6 +9,7 @@ #include #include #include +#include #include "sway/config.h" #include "sway/input/cursor.h" #include "sway/output.h" @@ -716,39 +717,138 @@ struct output_config *find_output_config(struct sway_output *output) { return get_output_config(id, output); } -void apply_output_config_to_outputs(struct output_config *oc) { - // Try to find the output container and apply configuration now.
