STM is a simple text menu libary written in C.
It allows to easily create text-based menu interface.
It's very easy.
Firstly create menu structure by filling an array:
struct menu menu_example[] = {
{ -1, NO_LABEL, ACTION2(main_title) },
{ 0, label("Create file"), NO_ACTION, HAS_SUBMENU },
{ 1, label("Are you sure?"), ACTION1(create_file) },
{ 1, label("Back"), NO_ACTION, EXIT },
{ 0, label("Delete file"), NO_ACTION, HAS_SUBMENU },
{ 1, label("Are you sure?"), ACTION1(delete_file) },
{ 1, label("Back"), NO_ACTION, EXIT },
{ 0, label("ls $pwd"), ACTION1(ls) },
{ 0, label("We need to go deeper [0]"), NO_ACTION, HAS_SUBMENU },
{ 1, label("And Deeper [1]"), ACTION2(and_deeper), HAS_SUBMENU },
{ 2, label("And Deeper [2]"), NO_ACTION, HAS_SUBMENU },
{ 3, label("And Deeper [3]"), ACTION12(stop_it, and_deeper), HAS_SUBMENU },
{ 4, label("And Deeper [4]"), ACTION1(stop_it) },
{ 4, label("Exit"), NO_ACTION, EXIT },
{ 3, label("Exit"), NO_ACTION, EXIT },
{ 2, label("Exit"), NO_ACTION, EXIT },
{ 1, label("Exit"), NO_ACTION, EXIT },
{ 0, label("Exit"), NO_ACTION, EXIT }
};
Where each entry have format:
{ level, label (truncate to 25), action, some options (EXIT or HAS_SUBMENU) }
To show menu just call show_menu:
show_menu(&menu_example[0], ARRAY_SIZE(menu_example))
Example output (from example/example.c):
