From faf15ee733681f14797d8b47078854a00f03f8fc Mon Sep 17 00:00:00 2001 From: Brian Ashworth Date: Sun, 17 Feb 2019 13:07:04 -0500 Subject: workspace_next_name: fallback to next available number This changes `workspace_next_name` to use the next available number as the workspace name instead of the number of outputs. This fixes the case where a number that is already in use could be returned. The workspace numbers in use have no relation to the number of outputs so it makes more sense to use the lowest available number --- sway/tree/workspace.c | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) (limited to 'sway/tree/workspace.c') diff --git a/sway/tree/workspace.c b/sway/tree/workspace.c index 68f1de50..73322491 100644 --- a/sway/tree/workspace.c +++ b/sway/tree/workspace.c @@ -336,16 +336,13 @@ char *workspace_next_name(const char *output_name) { if (target != NULL) { return target; } - // As a fall back, get the current number of active workspaces - // and return that + 1 for the next workspace's name - int ws_num = root->outputs->length; - int l = snprintf(NULL, 0, "%d", ws_num); - char *name = malloc(l + 1); - if (!sway_assert(name, "Could not allocate workspace name")) { - return NULL; - } - sprintf(name, "%d", ws_num++); - return name; + // As a fall back, use the next available number + char name[12] = ""; + unsigned int ws_num = 1; + do { + snprintf(name, sizeof(name), "%u", ws_num++); + } while (workspace_by_number(name)); + return strdup(name); } static bool _workspace_by_number(struct sway_workspace *ws, void *data) { -- cgit v1.2.3-70-g09d2
