<function name="getinfo" parent="debug" type="libraryfunc"> <description> Returns debug information about a function.</description> <realm>Shared and Menu</realm> <args> <arg name="funcOrStackLevel" type="function">Takes either a function or a number representing the stack level as an argument. Stack level 0 always corresponds to the debug.getinfo call, 1 would be the function calling debug.getinfo in most cases, and so on. Returns useful information about that function in a table.</arg> <arg name="fields" type="string" default="flnSu>">A string whose characters specify the information to be retrieved. * f - Populates the func field. * l - Populates the currentline field. * L - Populates the activelines field. * n - Populates the name and namewhat fields - only works if stack level is passed rather than function pointer. * S - Populates the location fields (lastlinedefined, linedefined, short_src, source and what). * u - Populates the argument and upvalue fields (isvararg, nparams, nups). * `f` - Populates the func field. * `l` - Populates the currentline field. * `L` - Populates the activelines field. * `n` - Populates the name and namewhat fields - only works if stack level is passed rather than function pointer. * `S` - Populates the location fields (lastlinedefined, linedefined, short_src, source and what). * `u` - Populates the argument and upvalue fields (isvararg, nparams, nups). * `>` - Causes this function to use the last argument to get the data from</arg> <arg name="function" type="function">Function to use.
