But why can I do it for the top level table and not inner ones ?
xtbl = {
[1] = { "A" },
[2.5] = { "A", "B" },
[.5] = { "A" },
[5] = { "A", "B", "C" }
}
function dump(tbl)
for i,f in pairs(tbl) do
print(i, #f, f)
for k,v in ipairs(f) do
print(' ---', k, v)
end
end
end
function remove(tbl, func)
for i, f in pairs( tbl ) do
for k,v in ipairs(f) do
if v == func then
f[k] = nil
-- table.remove(f, k)
end
end
if #f == 0 then
print('** remove', i)
tbl[i] = nil
-- table.remove(tbl, i)
end
end
end
dump(xtbl)
remove(xtbl, 'A')
print("Resultat")
dump(xtbl)
1 1 table: 0x7bf4a8
--- 1 A
5 3 table: 0x7c00b0
--- 1 A
--- 2 B
--- 3 C
2.5 2 table: 0x7bf3c8
--- 1 A
--- 2 B
0.5 1 table: 0x7bf1d0
--- 1 A
** remove 1
** remove 0.5
Resultat
5 3 table: 0x7c00b0
2.5 2 table: 0x7bf3c8
As you can see, I can't walk against inner ones :(
