Conflict Validation

func Validate(areas map[string]map[string]string) []string

Checks for intra-area conflicts: two different actions within the same area mapped to the same (non-empty) key. Cross-area duplicates are intentional and not reported — binding "d" to delete in both an inbox view and an email view is normal; the active view determines which handler fires.

Each returned string is a human-readable conflict description:

conflict in inbox: key "d" used for both "delete" and "archive"

Usage

Build the map from your config struct:

conflicts := keybind.Validate(map[string]map[string]string{
    "global": {
        "quit":     cfg.Global.Quit,
        "cancel":   cfg.Global.Cancel,
        "nav_up":   cfg.Global.NavUp,
        "nav_down": cfg.Global.NavDown,
    },
    "inbox": {
        "delete":  cfg.Inbox.Delete,
        "archive": cfg.Inbox.Archive,
        "open":    cfg.Inbox.Open,
    },
})
if len(conflicts) > 0 {
    // Surface to the user in a settings panel, or log on startup.
    for _, c := range conflicts {
        log.Printf("keybind conflict: %s", c)
    }
}
