From 5032acb7a574ce3e8dbfdfb1304d871e64ae68d6 Mon Sep 17 00:00:00 2001 From: Ryan Walklin Date: Wed, 31 Oct 2018 21:06:49 +0000 Subject: Add relative output transform This commit enhances the output transform command with options for a relative transform, i.e. the provided transform will be applied as an offset to the current transform. Append `clockwise` to rotate clockwise from the current rotation, or `anticlockwise` to rotate in the opposite direction. For example, if the output LVDS-1 is rotated 90 degrees clockwise, the command `output LVDS-1 transform 90 clockwise` will rotate the display to 180 degrees. All transform options are supported, including flipped transforms. Relative transforms can only be applied to a single output and cannot be used with a wildcard (*) output specifier. --- sway/commands/output/transform.c | 46 ++++++++++++++++++++++++++++++---------- 1 file changed, 35 insertions(+), 11 deletions(-) (limited to 'sway/commands/output/transform.c') diff --git a/sway/commands/output/transform.c b/sway/commands/output/transform.c index f9a94d64..c1555323 100644 --- a/sway/commands/output/transform.c +++ b/sway/commands/output/transform.c @@ -1,6 +1,8 @@ #include #include "sway/commands.h" #include "sway/config.h" +#include "log.h" +#include "sway/output.h" struct cmd_results *output_cmd_transform(int argc, char **argv) { if (!config->handler_context.output_config) { @@ -10,30 +12,52 @@ struct cmd_results *output_cmd_transform(int argc, char **argv) { return cmd_results_new(CMD_INVALID, "output", "Missing transform argument."); } - - struct output_config *output = config->handler_context.output_config; + enum wl_output_transform transform; if (strcmp(*argv, "normal") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_NORMAL; + transform = WL_OUTPUT_TRANSFORM_NORMAL; } else if (strcmp(*argv, "90") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_90; + transform = WL_OUTPUT_TRANSFORM_90; } else if (strcmp(*argv, "180") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_180; + transform = WL_OUTPUT_TRANSFORM_180; } else if (strcmp(*argv, "270") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_270; + transform = WL_OUTPUT_TRANSFORM_270; } else if (strcmp(*argv, "flipped") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_FLIPPED; + transform = WL_OUTPUT_TRANSFORM_FLIPPED; } else if (strcmp(*argv, "flipped-90") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_FLIPPED_90; + transform = WL_OUTPUT_TRANSFORM_FLIPPED_90; } else if (strcmp(*argv, "flipped-180") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_FLIPPED_180; + transform = WL_OUTPUT_TRANSFORM_FLIPPED_180; } else if (strcmp(*argv, "flipped-270") == 0) { - output->transform = WL_OUTPUT_TRANSFORM_FLIPPED_270; + transform = WL_OUTPUT_TRANSFORM_FLIPPED_270; } else { return cmd_results_new(CMD_INVALID, "output", "Invalid output transform."); } - + struct output_config *output = config->handler_context.output_config; config->handler_context.leftovers.argc = argc - 1; config->handler_context.leftovers.argv = argv + 1; + if (argc > 1 && + (strcmp(argv[1], "clockwise") == 0 || strcmp(argv[1], "anticlockwise") == 0)) { + if (!sway_assert(output->name != NULL, "Output config name not set")) { + return NULL; + } + if (strcmp(output->name, "*") == 0) { + return cmd_results_new(CMD_INVALID, "output", + "Cannot apply relative transform to all outputs."); + } + struct sway_output *s_output = output_by_name(output->name); + if (s_output == NULL) { + return cmd_results_new(CMD_INVALID, "output", + "Cannot apply relative transform to unknown output %s", output->name); + } + if (strcmp(argv[1], "anticlockwise") == 0) { + transform = wlr_output_transform_invert(transform); + } + struct wlr_output *w_output = s_output->wlr_output; + transform = wlr_output_transform_compose(w_output->transform, transform); + config->handler_context.leftovers.argv += 1; + config->handler_context.leftovers.argc -= 1; + } + output->transform = transform; return NULL; } -- cgit v1.2.3-54-g00ecf
