Hybridify. Hybrids. Create sync or async function to support both promise and callback-style APIs in same time. Using the power of [relike][].

Hybridifies all the selected functions in an object.

Handling/creating hybrid errors. Hybrid middleware between callbacks and throws. Helpful util for modules that have hybrid APIs and want when they use promises, directly to throw the errors; when use callbacks to pass errors to first argument of this call

Flexible and cross-platform executing commands. Hybrid, Async and Promise API.

Simple promisify async or sync function with sane defaults. Lower level than `promisify` thing. Can be used to create `promisify` method.

Make JavaScript functions that support both promise and callback styles.

Compose your control flow with absolute elegance. Support async/await, callbacks, thunks, generators, promises, observables, child processes and streams. Can power applications that need to have plugins. Useful for creating task, test and bench runners.

Check whether an object looks like Hybrid which is promises-a+ promise and callback api

Make promise to have support for callback api, it returns promise in that same time.

Create callback api from synchronous function. Same as `make-callback`, but won't handle generators and if async function is given returns it.

Create promise from sync, async, string, number, array and so on. Handle completion (results) and errors gracefully! Built on top of `relike`, used by `redolent` to build robust (hybrid) APIs.
