| concat(chunks) |
Concatenate a list of buffers. |
| constructorName(val) |
Get the constructor name from an instance. |
| countOf(val) |
Calculate the "length" of an array or value.Arrays return their length, single values return 1, and nil values return 0. This counts the number of elements that setOrPush would add. |
| defaultWhen(condition, items) |
Return the first element when condition is true and the second element when condition is false. |
| defer(ms) |
Resolve after a set amount of time. |
| doesExist(val) |
Check if a variable is not nil. |
| encode(chunks, encoding) |
Concatenate then encode a list of buffers. |
| ensureArray(val) |
|
| ensureArray(val) |
|
| entriesOf(map) |
Get entries of a map-like. |
| filterNil(list) |
Remove any null or undefined items from the list. |
| getConstructor(val) |
Get the constructor from an instance. |
| getHead(map, key) |
Get the first element from the specified key within a map of lists. |
| getHeadOrDefault(map, key, defaultValue) |
Get the first element from the specified key, within a map of lists, or a default value when the key does not exist or is nil. |
| getMethods(value) |
Get the methods from an instance and its prototypes. |
| getOrDefault(map, key, defaultValue) |
Get a map key or default value when the key does not exist or is nil. |
| getTestLogger(verbose) |
Get a test logger. Returns a null logger unless verbose is true or run under debug mode. |
| hasItems(val) |
Test if a value is an array with some items (length > 0).This is not a general replacement for .length > 0, since it is also a typeguard: if (hasItems(val)) else { val } will complain that val is never in the else branch, since it was proven not to be an array by this function, even if val is simply empty. |
| hasItems(val) |
|
| isDebug() |
Test if DEBUG mode is set.TODO: check variable value as well |
| isNil(val) |
Check if a value is nil. |
| leftPad(val, min, fill) |
|
| makeDict(map) |
Turns a map or dict into a dict |
| makeMap(val) |
Clone a map or map-like object into a new map. |
| mergeList(parts) |
Merge arguments, which may or may not be arrays, into one return that is definitely an array. |
| mergeList(parts) |
|
| mergeMap(target, source) |
Merge the source map into the target map, replacing keys that already exist. |
| mustCoalesce(values) |
Return the first value that is not nil.@todo: rename to mustDefault |
| mustExist(val) |
Assert that a variable is not nil and return the value. |
| mustFind(list, predicate) |
Find a value matching the given predicate or throw. |
| mustGet(map, key) |
Get an element from a Map and guard against nil values. |
| normalizeMap(map) |
(BETA) Normalize a map-like of values into a dict of lists of strings. |
| pairsToMap(pairs) |
Turns a list of name-value pairs into a map. |
| pushMergeMap(args) |
Merge the provided maps into a new map, merging keys that already exist by pushing new items. |
| pushMergeMap(args) |
|
| setOrPush(map, key, val) |
Set a map key to a new array or push to the existing value. |
| signal(signals) |
|
| spyLogger(spies) |
Create a spy logger using the provided methods, which returns itself as a child. |
| timeout(ms, oper) |
Reject after a set amount of time if the original promise has not yet resolved. |
| trim(val, max, tail) |
|
| waitForChild(child) |
Wait for a child process to exit, collecting output, errors, and exit status. |
| writeValue(stream, value) |
