hands alternatives and similar packages
Based on the "Goroutines" category.
Alternatively, view hands alternatives based on common mentions on social networks and blogs.
-
goworker
goworker is a Go-based background worker that runs 10 to 100,000* times faster than Ruby-based workers. -
pool
:speedboat: a limited consumer goroutine or unlimited goroutine pool for easier goroutine handling and cancellation -
Go-Taskflow
A pure go General-purpose Task-parallel Programming Framework with integrated visualizer and profiler -
async
A safe way to execute functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery. -
go-workers
DISCONTINUED. 👷 Library for safely running groups of workers concurrently or consecutively that require input and output through channels -
gollback
Go asynchronous simple function utilities, for managing execution of closures and callbacks -
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive. -
gpool
gpool - a generic context-aware resizable goroutines pool to bound concurrency based on semaphore. -
gowl
Gowl is a process management and process monitoring tool at once. An infinite worker pool gives you the ability to control the pool and processes and monitor their status. -
kyoo
Unlimited job queue for go, using a pool of concurrent workers processing the job queue entries -
execpool
A pool that spins up a given number of processes in advance and attaches stdin and stdout when needed. Very similar to FastCGI but works for any command. -
concurrency-limiter
Concurrency limiter with support for timeouts , dynamic priority and context cancellation of goroutines. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way. It supports specifying the overall timeout to avoid blocking. -
queue
package queue gives you a queue group accessibility. Helps you to limit goroutines, wait for the end of the all goroutines and much more. -
async-job
AsyncJob is an asynchronous queue job manager with light code, clear and speed. I hope so ! 😬

Hands
“Dedicated to Brother Chang”
Hands is a process controller used to control the execution and return strategies of multiple goroutines.
Getting started
A simple example
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
n++
return nil
})
err := controller.Run()
if err != nil {
// ...
}
fmt.Println(n)
// Output:
// 1
Use the Do
method to add a task, use the Run
method to start the task(s).
TaskOption
TaskOption
is used to set some metadata for the task.
func Priority(priority int32) TaskOption
Use the Priority
method to set a priority for a task. The higher the priority, the higher the execution order.
(hands.P()
is an alias for hands.Priority()
.)
controller := New()
controller.Do(func(ctx context.Context) error {
fmt.Println("3")
return nil
}, hands.P(1))
controller.Do(func(ctx context.Context) error {
fmt.Println("2")
return nil
}, hands.P(2))
controller.Do(func(ctx context.Context) error {
fmt.Println("1")
return nil
}, hands.P(3))
controller.Run()
// Output:
// 1
// 2
// 3
HandOption
HandOption is used to control the execution strategy of the task.
func Fastest() HandOption
Fastest()
: When a task is completed, return immediately.
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
time.Sleep(time.Duration(10) * time.Millisecond)
n += 1
return nil
})
controller.Do(func(ctx context.Context) error {
n += 2
return nil
})
controller.Run(hands.Fastest())
fmt.Println(n)
// Output:
// 2
func Percentage(percentage float32) HandOption
When a certain percentage of tasks are executed, the results are returned.
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
n++
return nil
})
controller.Do(func(ctx context.Context) error {
n++
return nil
})
controller.Do(func(ctx context.Context) error {
n++
return nil
})
controller.Do(func(ctx context.Context) error {
n++
return nil
})
controller.Run(hands.Percentage(0.5))
fmt.Println(n)
// Output:
// 2
func Between(l, r int32) HandOption
Between()
: Only execute tasks with a priority within the specified range.
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
n += 1
return nil
}, hands.P(1))
controller.Do(func(ctx context.Context) error {
n += 2
return nil
}, hands.P(2))
controller.Do(func(ctx context.Context) error {
n += 3
return nil
}, hands.P(3))
controller.Do(func(ctx context.Context) error {
n += 4
return nil
}, hands.P(4))
controller.Run(hands.Between(2, 3))
fmt.Println(n)
// Output:
// 5
Note: If the use the controller.Run()
method, tasks outside the Between()
will not be executed, you can use the controller.RunAll()
method to allow other priority tasks to be executed asynchronously.
...
controller.RunAll(hands.Between(2, 3))
fmt.Println(n)
time.Sleep(time.Duration(10) * time.Millisecond)
fmt.Println(n)
// Output:
// 5
// 10
func In(in []int32) HandOption
In()
: Only execute tasks in the specified priority list.
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
n += 1
return nil
}, hands.P(1))
controller.Do(func(ctx context.Context) error {
n += 2
return nil
}, hands.P(2))
controller.Do(func(ctx context.Context) error {
n += 3
return nil
}, hands.P(3))
controller.Do(func(ctx context.Context) error {
n += 4
return nil
}, hands.P(4))
controller.Run(hands.In([]int32{2, 4}))
fmt.Println(n)
// Output:
// 6
Yes, the controller.RunAll()
method can also be used here.
...
controller.RunAll(hands.In([]int32{2, 4}))
fmt.Println(n)
time.Sleep(time.Duration(10) * time.Millisecond)
fmt.Println(n)
// Output:
// 6
// 10
func WithContext(ctx context.Context) HandOption
Make the task use the specified context.
c, cancel := context.WithTimeout(context.Background(), 50*time.Millisecond)
defer cancel()
controller := hands.New()
controller.Do(func(ctx context.Context) error {
time.Sleep(time.Duration(100) * time.Millisecond)
return nil
})
err := controller.Run(hands.WithContext(c))
fmt.Println(err.Error())
// Output:
// context deadline exceeded
Callback after all tasks have been executed
n := 0
controller := hands.New()
controller.Do(func(ctx context.Context) error {
time.Sleep(time.Duration(10) * time.Millisecond)
n++
return nil
})
controller.Do(func(ctx context.Context) error {
time.Sleep(time.Duration(10) * time.Millisecond)
n++
return nil
})
controller.Do(func(ctx context.Context) error {
n += 5
return nil
})
// Here.
controller.Done(func() {
// `True`
assert.Equal(t, n, 7)
})
controller.RunAll(Fastest())
// `True`
assert.Equal(t, n, 5)
time.Sleep(time.Duration(500) * time.Millisecond)
