how to count objects? lua scripting

[Soulbuster]

so I don't know much about lua scripts and was wondering if there is a way to count objects.

something along the lines of : "for each object in objects" or an maybe the devs have created inbuilt method like "object.count()".

I'm trying to get naval capacity to increase from something other than space ports or population.
I don't see any modifiers for this except for the naval_capacity_add % increment. while this would suffice for the most part but it's not pretty and for my purposed it would be kinda messy - I'd rather find a way to have a fixed amount :/

Would really appreciate the info ^_^

count_ships - compares number of ships in a fleet that matches the [limit = {..}]
count_owned_ships
count_pop_factions - Counts the amount of pop factions which fill a requirement and compare it to a number
count_deposits - counts number of deposits of given type on planet or tile
count_tech_options - Compares the amount of tech options a country has against a value, can specify which area
count_armies - Counts the amount of armies which fill a requirement and compare it to a number
count_war_participants -
count_potential_war_participants -
num_fleets - checks if a country has the said number of fleets
num_ships - checks if a country has the said number of ships
num_ethics - compares the number of ethics with a value

war_begun_num_fleets_gone_mia - Checks how many fleets went MIA due to the war declaration
war_begun_num_wormhole_stations_destroyed - Checks how many fleets went MIA due to the war declaration

You can do = > <, like count_ships > 8 or count_deposits = 5.

There should be a few thing on that list you can use...
