Documentation
arguments :: [ArgCompletion] Source #
The list of arguments supported by the program.
annotateOpCode :: Maybe String -> Timestamp -> Annotator Source #
Wraps an OpCode in a MetaOpCode while also adding a comment
about what generated the opcode.
Arguments
| :: Bool | Whether to print moves |
| -> AlgorithmOptions | Algorithmic options to apply |
| -> Table | The starting table |
| -> Int | Remaining length |
| -> Int | Max node name len |
| -> Int | Max instance name len |
| -> [MoveJob] | Current command list |
| -> Score | Score at which to stop |
| -> IO (Table, [MoveJob]) | The resulting table and commands |
Start computing the solution at the given depth and recurse until we find a valid solution or we exceed the maximum depth.
printStats :: List -> List -> IO () Source #
Displays the cluster stats.
maybeExecJobs :: Options -> [a] -> List -> List -> [JobSet] -> IO (Result ()) Source #
Executes the jobs, if possible and desired.
selectGroup :: Options -> List -> List -> List -> IO (String, (List, List)) Source #
Select the target node group.
checkCluster :: Int -> List -> List -> IO () Source #
Do a few checks on the cluster data.
checkGroup :: Bool -> Int -> String -> List -> List -> IO () Source #
Do a few checks on the selected group data.
