Function; foreachi - HWRM/KarosGraveyard GitHub Wiki

foreachi(<tTable>, <fFunction>)

Description

(from LUA 4 Manual: 6.1 Basic Functions)

"Executes the given <fFunction> over the numerical indices of <tTable>. For each index, the function is called with the index and respective value as arguments. Indices are visited in sequential order, from 1 to n, where n is the result of getn(<tTable>) (see Section 6.1). If the function returns any non-nil value, then the loop is broken, and this value is returned as the final value of foreachi. This function could be defined in Lua:"

function foreachi (t, f)
    for i=1, getn(t) do
        local res = f(i, t[i])
        if res then return res end
    end
end

Example

Arguments

<tTable>: the table to traverse.
<fFunction>: the function to execute over all elements of <tTable>. Note: do not add trailing parentheses when entering the function name.
