From eb770e88b7396e892898d6a71867d2a603e707ff Mon Sep 17 00:00:00 2001 From: Ed Younis Date: Fri, 12 Jul 2019 19:04:29 -0700 Subject: [PATCH] Implement input_cmd_xkb_file (#3999) Adds a new commend "xkb_file", which constructs the internal xkb_keymap from a xkb file rather than an RMLVO configuration. This allows greater flexibility when specifying xkb configurations. An xkb file can be dumped with the xkbcomp program. --- include/sway/commands.h | 1 + include/sway/config.h | 3 +++ sway/commands/input.c | 5 ++-- sway/commands/input/xkb_file.c | 28 ++++++++++++++++++++ sway/config/input.c | 9 +++++++ sway/input/keyboard.c | 47 +++++++++++++++++++++++++++++----- sway/meson.build | 1 + sway/sway-input.5.scd | 5 ++++ 8 files changed, 90 insertions(+), 9 deletions(-) create mode 100644 sway/commands/input/xkb_file.c diff --git a/include/sway/commands.h b/include/sway/commands.h index ddee2994d..7ff3b651e 100644 --- a/include/sway/commands.h +++ b/include/sway/commands.h @@ -257,6 +257,7 @@ sway_cmd input_cmd_scroll_method; sway_cmd input_cmd_tap; sway_cmd input_cmd_tap_button_map; sway_cmd input_cmd_xkb_capslock; +sway_cmd input_cmd_xkb_file; sway_cmd input_cmd_xkb_layout; sway_cmd input_cmd_xkb_model; sway_cmd input_cmd_xkb_numlock; diff --git a/include/sway/config.h b/include/sway/config.h index c5558c0d1..f1426453a 100644 --- a/include/sway/config.h +++ b/include/sway/config.h @@ -138,6 +138,9 @@ struct input_config { char *xkb_options; char *xkb_rules; char *xkb_variant; + char *xkb_file; + + bool xkb_file_is_set; int xkb_numlock; int xkb_capslock; diff --git a/sway/commands/input.c b/sway/commands/input.c index 588ef2d58..2289ede54 100644 --- a/sway/commands/input.c +++ b/sway/commands/input.c @@ -28,6 +28,7 @@ static struct cmd_handler input_handlers[] = { { "scroll_method", input_cmd_scroll_method }, { "tap", input_cmd_tap }, { "tap_button_map", input_cmd_tap_button_map }, + { "xkb_file", input_cmd_xkb_file }, { "xkb_layout", input_cmd_xkb_layout }, { "xkb_model", input_cmd_xkb_model }, { "xkb_options", input_cmd_xkb_options }, @@ -48,8 +49,8 @@ static struct cmd_handler input_config_handlers[] = { static void retranslate_keysyms(struct input_config *input_config) { for (int i = 0; i < config->input_configs->length; ++i) { struct input_config *ic = config->input_configs->items[i]; - if (ic->xkb_layout) { - // this is the first config with xkb_layout + if (ic->xkb_layout || ic->xkb_file) { + // this is the first config with xkb_layout or xkb_file if (ic->identifier == input_config->identifier) { translate_keysyms(ic); } diff --git a/sway/commands/input/xkb_file.c b/sway/commands/input/xkb_file.c new file mode 100644 index 000000000..063f544df --- /dev/null +++ b/sway/commands/input/xkb_file.c @@ -0,0 +1,28 @@ +#define _POSIX_C_SOURCE 200809L +#include "sway/config.h" +#include "sway/commands.h" +#include "sway/input/input-manager.h" +#include "log.h" + +struct cmd_results *input_cmd_xkb_file(int argc, char **argv) { + struct cmd_results *error = NULL; + if ((error = checkarg(argc, "xkb_file", EXPECTED_EQUAL_TO, 1))) { + return error; + } + struct input_config *ic = config->handler_context.input_config; + if (!ic) { + return cmd_results_new(CMD_FAILURE, "No input device defined."); + } + + if (strcmp(argv[0], "-") == 0) { + free(ic->xkb_file); + ic->xkb_file = NULL; + } else { + ic->xkb_file = strdup(argv[0]); + } + ic->xkb_file_is_set = true; + + sway_log(SWAY_DEBUG, "set-xkb_file for config: %s file: %s", + ic->identifier, ic->xkb_file); + return cmd_results_new(CMD_SUCCESS, NULL); +} diff --git a/sway/config/input.c b/sway/config/input.c index b5be4f266..ad4a64eef 100644 --- a/sway/config/input.c +++ b/sway/config/input.c @@ -39,6 +39,7 @@ struct input_config *new_input_config(const char* identifier) { input->repeat_rate = INT_MIN; input->xkb_numlock = INT_MIN; input->xkb_capslock = INT_MIN; + input->xkb_file_is_set = false; return input; } @@ -95,6 +96,11 @@ void merge_input_config(struct input_config *dst, struct input_config *src) { if (src->tap_button_map != INT_MIN) { dst->tap_button_map = src->tap_button_map; } + if (src->xkb_file_is_set) { + free(dst->xkb_file); + dst->xkb_file = src->xkb_file ?
