[Bug] REPL auto-import does not work.

[laurensvalk]

When starting the REPL, everything in the pybricks package is supposed to be pre-imported.

This no longer works because:

    for (size_t i = 0; i < MP_ARRAY_SIZE(pybricks_globals_table); i++) {
        mp_rom_obj_t module = pybricks_globals_table[i].value;
        if (mp_obj_is_type(module, &mp_type_module)) {
            // Import everything from the module.
            mp_import_all((mp_obj_t)module);
        }
    }

and the modules are no longer included in pybricks_globals_table.

While we are doing this, we could consider importing everything, including those from MicroPython modules. I'll have a look at the RAM cost.

On Prime Hub, when importing everything:

stack: 604 out of 36976
GC: total: 259008, used: 2272, free: 256736
 No. of 1-blocks: 14, 2-blocks: 3, max blk sz: 112, max free sz: 15915

When importing only pybricks modules (+36 bytes build size for the check):

stack: 604 out of 36976
GC: total: 259008, used: 1008, free: 258000
 No. of 1-blocks: 20, 2-blocks: 4, max blk sz: 19, max free sz: 16116

So, about 1.2K extra heap used for importing everything from the (currently included) MicroPython modules.

Now check on Move Hub. Oh wait, no REPL. 😆

So I think we can just import everything. If anyone ever needs the REPL and use RAM to the limits, they can just run an empty script that raises the KeyboardInterrupt.

Are we sure that there are and never will be name conflicts for importing * from *? It seems like it would be safer to import * from pybricks modules but import module for everything else.

[laurensvalk]

OK, I'll restore importing Pybricks modules only.

[dlech]

I like the idea of importing the other modules too. Maybe we could import * if module starts with pybricks else import module?

[laurensvalk]

Sure. Will do that tomorrow.

mp_import_name and several other related calls just fetch the module but don't register it as loaded. Simply doing it like pybricks/pybricks-micropython@7b57a7a works though.
