Change Log

All notable changes to this project will be documented in this file. This change log follows the conventions of keepachangelog.com.

1.3.0

Changed

Renamed sequenced to sequenced-par to more explicitly state its execution type.

Added

Proper sequenced function that executes its contents sequentially.

Fixed

Case in sequenced-par where a list of tasks would've been transformed to a task of lists of lists Documentation error.

1.2.1

Changed

Given the ambiguity in errors when mixing parallel with non-parallel executions, failed parallel executions do not contain collections of Throwable objects anymore, but rather a single Throwable object pertaining to the first execution that failed.

Added

Function recover-as, that resets a failed task to a successful task, containing a user-provided value.

Syntax for recover and recover-as in do-tasks block.

1.2.0

Changed

Failures have now been replaced with plain Throwable objects. The failure map format of previous versions (containg the message and a vector stack trace) has been deprecated and removed.

Failed parallel tasks now contain a collection of all Throwable objects of all the tasks that failed during execution.

Removed

Old representation of failures and errors.

0.1.7 - 1.1.1

Changed

Result is now hidden and contained within Task. Users need not manipulate it anymore.

Its functionality has also been hidden away.

Task has now been made completely compositional. Any task execution now returns a new task, that one may continue composing with other tasks.

Removed

Public Result functionality.

0.1.6

Changed

fold in Result is now a macro to avoid unnecessary function calls

Added

Function from-result on Task, which promotes a Result to a Task Invariant here is: for some Result r, (run (from-result r)) == r

0.1.5

Changed

get! for Result now returns the interval value for both failure and success

Added

get-or-else function for Task. This runs the task synchronously and then returns the inner result value. Equivalent to (halfling.result/get! (halfling.task/run task))

0.1.4

Changed

  • Tasks and Results are type-checked more accurately
  • Result is now a deftype

Added

  • recover function added for both Task and Result. This applies a function on a result in case of failure

0.1.3

Changed

  • Renamed ap to mapply, because ap wasn't really the true ap function, but rather the applicative apply-n function.

0.1.2

Changed

  • Change fold for Result to apply its functions directly on the values of those results and not the results themselves

0.1.1

Changed

  • Task behaviour to support parallel execution
  • ap, zip and sequenced support parallel execution

Added

  • p-map, an alternative to clojures pmap, that uses the library to map a function in parallel

0.1.0

Added

  • Library release
