From a0c5a0bb30af3cc132715e60cf3d87a77f88a095 Mon Sep 17 00:00:00 2001 From: "S. Christoffer Eliesen" Date: Thu, 19 Nov 2015 16:37:48 +0100 Subject: [PATCH] cmd_bindsym: Detect/handle duplicates. Also replace `bindsym_sort` with function `sway_binding_cmp` that takes all data into account when comparing. --- include/config.h | 4 ++++ sway/commands.c | 30 ++++++++++------------------- sway/config.c | 49 ++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 63 insertions(+), 20 deletions(-) diff --git a/include/config.h b/include/config.h index 82aa71bf..3bdbdb7b 100644 --- a/include/config.h +++ b/include/config.h @@ -104,6 +104,10 @@ void free_output_config(struct output_config *oc); int workspace_output_cmp_workspace(const void *a, const void *b); +int sway_binding_cmp(const void *a, const void *b); +int sway_binding_cmp_keys(const void *a, const void *b); +void free_sway_binding(struct sway_binding *sb); + /** * Global config singleton. */ diff --git a/sway/commands.c b/sway/commands.c index 6e9137c0..5b3b1d0f 100644 --- a/sway/commands.c +++ b/sway/commands.c @@ -132,19 +132,6 @@ static struct cmd_results *checkarg(int argc, const char *name, enum expected_ar return error; } -static int bindsym_sort(const void *_lbind, const void *_rbind) { - const struct sway_binding *lbind = *(void **)_lbind; - const struct sway_binding *rbind = *(void **)_rbind; - unsigned int lmod = 0, rmod = 0, i; - - // Count how any modifiers are pressed - for (i = 0; i < 8 * sizeof(lbind->modifiers); ++i) { - lmod += lbind->modifiers & 1 << i; - rmod += rbind->modifiers & 1 << i; - } - return (rbind->keys->length + rmod) - (lbind->keys->length + lmod); -} - static struct cmd_results *cmd_bindsym(int argc, char **argv) { struct cmd_results *error = NULL; if ((error = checkarg(argc, "bindsym", EXPECTED_MORE_THAN, 1))) { @@ -159,8 +146,7 @@ static struct cmd_results *cmd_bindsym(int argc, char **argv) { binding->command = join_args(argv + 1, argc - 1); list_t *split = split_string(argv[0], "+"); - int i; - for (i = 0; i < split->length; ++i) { + for (int i = 0; i < split->length; ++i) { // Check for a modifier key int j; bool is_mod = false; @@ -176,9 +162,7 @@ static struct cmd_results *cmd_bindsym(int argc, char **argv) { xkb_keysym_t sym = xkb_keysym_from_name(split->items[i], XKB_KEYSYM_CASE_INSENSITIVE); if (!sym) { error = cmd_results_new(CMD_INVALID, "bindsym", "Unknown key '%s'", (char *)split->items[i]); - list_free(binding->keys); - free(binding->command); - free(binding); + free_sway_binding(binding); list_free(split); return error; } @@ -188,10 +172,16 @@ static struct cmd_results *cmd_bindsym(int argc, char **argv) { } free_flat_list(split); - // TODO: Check if there are other commands with this key binding struct sway_mode *mode = config->current_mode; + int i = list_seq_find(mode->bindings, sway_binding_cmp_keys, binding); + if (i > -1) { + sway_log(L_DEBUG, "bindsym - '%s' already exists, overwriting", argv[0]); + struct sway_binding *dup = mode->bindings->items[i]; + free_sway_binding(dup); + list_del(mode->bindings, i); + } list_add(mode->bindings, binding); - list_sort(mode->bindings, bindsym_sort); + list_sort(mode->bindings, sway_binding_cmp); sway_log(L_DEBUG, "bindsym - Bound %s to command %s", argv[0], binding->command); return cmd_results_new(CMD_SUCCESS, NULL, NULL); diff --git a/sway/config.c b/sway/config.c index 2fceb6e2..d70c016a 100644 --- a/sway/config.c +++ b/sway/config.c @@ -383,3 +383,52 @@ int workspace_output_cmp_workspace(const void *a, const void *b) { const struct workspace_output *wsa = a, *wsb = b; return lenient_strcmp(wsa->workspace, wsb->workspace); } + +int sway_binding_cmp_keys(const void *a, const void *b) { + const struct sway_binding *binda = a, *bindb = b; + + if (binda->modifiers > bindb->modifiers) { + return 1; + } else if (binda->modifiers < bindb->modifiers) { + return -1; + } + + if (binda->keys->length > bindb->keys->length) { + return 1; + } else if (binda->keys->length < bindb->keys->length) { + return -1; + } + + for (int i = 0; i < binda->keys->length; i++) { + xkb_keysym_t *ka = binda->keys->items[i], + *kb = bindb->keys->items[i]; + if (*ka > *kb) { + return 1; + } else if (*ka < *kb) { + return -1; + } + } + return 0; +} + +int sway_binding_cmp(const void *a, const void *b) { + int cmp = 0; + if ((cmp = sway_binding_cmp_keys(a, b)) != 0) { + return cmp; + } + const struct sway_binding *binda = a, *bindb = b; + return lenient_strcmp(binda->command, bindb->command); +} + +void free_sway_binding(struct sway_binding *binding) { + if (binding->keys) { + for (int i = 0; i < binding->keys->length; i++) { + free(binding->keys->items[i]); + } + list_free(binding->keys); + } + if (binding->command) { + free(binding->command); + } + free(binding); +}
