Re: Sorting dictionary tables by value

[Kevin Krumwiede <kjkrum@...>]

Thanks for your response.  Instead of rewriting all my
code, I got the bright idea of simply copying my data
into another table for sorting and output.  Something
like:

function GetSortedTable(tbl)
    local meta = {};
    for foo, bar in pairs(tbl) do
        table.insert(meta, {key=foo, value=bar});
    end
    table.sort(meta, function(a,b) return a.value >
b.value; end);
    return meta;
end

local sorted = GetSortedTable(someTable);
for idx, row in ipairs(sorted) do
    -- something with row.key and row.value
end
