From 415a48ac6387a62a59adb8ed1168e851509a0ce3 Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Sat, 29 Sep 2018 11:06:07 +1000 Subject: [PATCH] Make gaps implementation consistent with i3-gaps This changes our gaps implementation to behave like i3-gaps. Our previous implementation allowed you to set gaps on a per container basis. This isn't supported by i3-gaps and doesn't seem to have a practical use case. The gaps_outer and gaps_inner properties on containers are now removed as they just read the gaps_inner from the workspace. `gaps inner|outer ` no longer changes the gaps for all workspaces. It only sets defaults for new workspaces. `gaps inner|outer current|workspace|all set|plus|minus ` is now runtime only, and the workspace option is now removed. `current` now sets gaps for the current workspace as opposed to the current container. `workspace gaps inner|outer ` is now implemented. This sets defaults for a workspace. This also fixes a bug where changing the layout of a split container from linear to tabbed would cause gaps to not be applied to it until you switch to another workspace and back. --- include/sway/config.h | 2 + include/sway/tree/container.h | 3 - include/sway/tree/workspace.h | 7 +- sway/commands/gaps.c | 312 +++++++++++++++++----------------- sway/commands/layout.c | 3 +- sway/commands/workspace.c | 38 +++++ sway/tree/container.c | 2 +- sway/tree/workspace.c | 18 +- 8 files changed, 215 insertions(+), 170 deletions(-) diff --git a/include/sway/config.h b/include/sway/config.h index af5c7a188..82be26ca3 100644 --- a/include/sway/config.h +++ b/include/sway/config.h @@ -173,6 +173,8 @@ struct output_config { struct workspace_config { char *workspace; char *output; + int gaps_inner; + int gaps_outer; }; struct bar_config { diff --git a/include/sway/tree/container.h b/include/sway/tree/container.h index 5e281a2f8..b865a0f20 100644 --- a/include/sway/tree/container.h +++ b/include/sway/tree/container.h @@ -94,9 +94,6 @@ struct sway_container { // The gaps currently applied to the container. double current_gaps; - bool has_gaps; - double gaps_inner; - double gaps_outer; struct sway_workspace *workspace; // NULL when hidden in the scratchpad struct sway_container *parent; // NULL if container in root of workspace diff --git a/include/sway/tree/workspace.h b/include/sway/tree/workspace.h index c8220b395..efdae5a1a 100644 --- a/include/sway/tree/workspace.h +++ b/include/sway/tree/workspace.h @@ -32,10 +32,9 @@ struct sway_workspace { enum sway_container_layout layout; enum sway_container_layout prev_split_layout; - double current_gaps; - bool has_gaps; - double gaps_inner; - double gaps_outer; + int current_gaps; + int gaps_inner; + int gaps_outer; struct sway_output *output; // NULL if no outputs are connected list_t *floating; // struct sway_container diff --git a/sway/commands/gaps.c b/sway/commands/gaps.c index d676e475b..3791fcb4f 100644 --- a/sway/commands/gaps.c +++ b/sway/commands/gaps.c @@ -1,4 +1,5 @@ #include +#include #include "sway/commands.h" #include "sway/config.h" #include "sway/tree/arrange.h" @@ -13,172 +14,167 @@ enum gaps_op { GAPS_OP_SUBTRACT }; -enum gaps_scope { - GAPS_SCOPE_ALL, - GAPS_SCOPE_WORKSPACE, - GAPS_SCOPE_CURRENT +struct gaps_data { + bool inner; + enum gaps_op operation; + int amount; }; +// gaps edge_gaps on|off|toggle +static struct cmd_results *gaps_edge_gaps(int argc, char **argv) { + struct cmd_results *error; + if ((error = checkarg(argc, "gaps", EXPECTED_AT_LEAST, 2))) { + return error; + } + + if (strcmp(argv[1], "on") == 0) { + config->edge_gaps = true; + } else if (strcmp(argv[1], "off") == 0) { + config->edge_gaps = false; + } else if (strcmp(argv[1], "toggle") == 0) { + if (!config->active) { + return cmd_results_new(CMD_INVALID, "gaps", + "Cannot toggle gaps while not running."); + } + config->edge_gaps = !config->edge_gaps; + } else { + return cmd_results_new(CMD_INVALID, "gaps", + "gaps edge_gaps on|off|toggle"); + } + arrange_root(); + return cmd_results_new(CMD_SUCCESS, NULL, NULL); +} + +// gaps inner|outer +static struct cmd_results *gaps_set_defaults(int argc, char **argv) { + struct cmd_results *error = checkarg(argc, "gaps", EXPECTED_EQUAL_TO, 2); + if (error) { + return error; + } + + bool inner; + if (strcasecmp(argv[0], "inner") == 0) { + inner = true; + } else if (strcasecmp(argv[0], "outer") == 0) { + inner = false; + } else { + return cmd_results_new(CMD_INVALID, "gaps", + "Expected 'gaps inner|outer '"); + } + + char *end; + int amount = strtol(argv[1], &end, 10); + if (strlen(end) && strcasecmp(end, "px") != 0) { + return cmd_results_new(CMD_INVALID, "gaps", + "Expected 'gaps inner|outer '"); + } + + if (inner) { + config->gaps_inner = amount; + } else { + config->gaps_outer = amount; + } + return cmd_results_new(CMD_SUCCESS, NULL, NULL); +} + +static void configure_gaps(struct sway_workspace *ws, void *_data) { + struct gaps_data *data = _data; + int *prop = data->inner ?
