[solved] How to move WML table

[ZombieKnight]

Hi
I've got this saved in

Code: Select all

wml.variables["save_data"]

How to move all of its content into wml.variables?
Any ideas?

[white_haired_uncle]

wml.array_access.get

[ZombieKnight]

Sorry?
I've found the wiki page (https://wiki.wesnoth.org/LuaAPI/wml#wml ... access.get) and I have no idea how to use it for moving wml table right into wml.variables.
Could you explain it a bit more?
It's a function that just returns a value or does it do even something else?
What is this supposed to do:

Code: Select all

function get_recall_list(side)
    wesnoth.fire("store_unit", { x = "recall", variable = "LUA_recall_list" })
    local l = wml.array_access.get "LUA_recall_list"
    wml.variables.LUA_recall_list = nil
    return l
end

wml.variables is not real table, so you cant insert another table into it. For regular tables it is just table.insert(destination_table, wml_table).

[ZombieKnight]

Okay,
So I've got a table of tables... how to put these tables into wml.variables then?
What are you thinking about?
...
Or the first table is on the right place... so can't I just remove those [save_data] tags from it and leave it there?

[Ravana]

You cant put them to wml.variables. You can think of wml.variables as function, not as table. It reflects state of wml variables, but itself is not wml variables.

[ZombieKnight]

Oh...
So where to put them so I can acces them later using
wml.variables[my_var]?

[Ravana]

Assign them with the API you have available to create wml variables. Including wml.variables if you prefer. Those like set_variable, set_variables, wml.array_access.set, wml.array_variables, wml.variables_proxy.

Loading it back in is going to be pretty much the same procedure as saving it was. The scalar ones should be easy, literally the exact same loop you used to save but flip the assignment. Container variables will be a bit more tricky. I think something along these lines may work?

Code: Select all

local tags = {}
for index, elem in ipairs(save_data) do
	tags[elem.tag] = true
end
for tag,_ in pairs(tags) do
	wml.array_variables[tag] = wml.child_array(save_data, tag)
end

There might be a more efficient way (as each assignment here is probably looping over all of save_data again), but I think that approach should do the job.

[ZombieKnight]

Ok, I'll try it but... have you seen the code t
for erasing all the container variables?

Code: Select all

for index, elem in ipairs(wml.all_variables) do
wml.variables[""..elem[1].."[0]"] = nil end

[ZombieKnight]

There might be a more efficient way (as each assignment here is probably looping over all of save_data again), but I think that approach should do the job.

Not sure... you meant wml.variables.save_data?
I extract the data from global using this:

Code: Select all

wesnoth.wml_actions.get_global_variable(
{
namespace="Bandits_from_Brown_Hills",
to_local="save_data",
from_global="save_file",
side=1,
}
)

[ZombieKnight]

...And I really think your code is really wrong...

Code: Select all

for index, elem in ipairs(wml.variables["save_data"]) do
	std_print(index, elem)
end

returns

Code: Select all

1       table: 0x5596a93b5720
2       table: 0x5596b4cc6200

[ZombieKnight]

I have no idea how I made this ...
Ladies and gentlemen, I present you wml.variables replacer:

Code: Select all

wesnoth.wml_actions.get_global_variable(
{
namespace="Bandits_from_Brown_Hills",
to_local="save_data",
from_global="save_file",
side=1,
}
)
for key, value in pairs(wml.variables["save_data"]) do
    if type(value) ~= "table" then
        wml.variables[key] = value
    end
end
for index, elem in ipairs(wml.variables["save_data"]) do
    if elem[1] ~= "save_data" then
    	local i = 0
        while wml.variables[""..elem[1].."["..i.."]"] ~= nil do
            i = i + 1
        end
        wml.variables[""..elem[1].."["..i.."]"] = elem[2]
    end
end
wml.variables["save_data"] = nil

Only units, menu items, events, and sides to go!
Thanks for help so far (and I'd be glad if you'd keep helping me ^^)
