Functions

char * glob_path (const char *path)
 This function resolves ~ in pathnames.
bool path_exists (const char *path)
 Checks if the given path exists by calling stat().
void ungrab_all_keys (xcb_connection_t *conn)
 Ungrabs all keys, to be called before re-grabbing the keys because of a mapping_notify event or a configuration file reload.
static void grab_keycode_for_binding (xcb_connection_t *conn, Binding *bind, uint32_t keycode)
Binding * get_binding (uint16_t modifiers, xcb_keycode_t keycode)
 Returns a pointer to the Binding with the specified modifiers and keycode or NULL if no such binding exists.
void translate_keysyms ()
 Translates keysymbols to keycodes for all bindings which use keysyms.
void grab_all_keys (xcb_connection_t *conn, bool bind_mode_switch)
 Grab the bound keys (tell X to send us keypress events for those keycodes)
void switch_mode (xcb_connection_t *conn, const char *new_mode)
 Switches the key bindings to the given mode, if the mode exists.
static char * get_config_path ()
static void parse_configuration (const char *override_configpath)
void load_configuration (xcb_connection_t *conn, const char *override_configpath, bool reload)
 Reads the configuration from ~/.i3/config or /etc/i3/config if not found.
