README
## Parallel fn
* Run functions in parallel.
* Limit the number of goroutines running at the same time.
## Installation
```bash
go get -u github.com/rafaeljesus/parallel-fn
```
## Usage
### Run
```go
package main
import (
"errors"
"github.com/rafaeljesus/parallel-fn"
)
func main() {
timeout := time.After(2 * time.Second)
fn1 := func() error { return nil }
fn2 := func() error { return errors.New("BOOM!") }
for {
select {
case err := <-Run(fn1, fn2):
// catch errors
case <-timeout:
// handle timeout
}
}
}
```
### RunLimit
```go
package main
import (
"errors"
"github.com/rafaeljesus/parallel-fn"
)
func main() {
timeout := time.After(2 * time.Second)
fn1 := func() error { return nil }
fn2 := func() error { return errors.New("BOOM!") }
fn3 := func() error { nil }
fn4 := func() error { nil }
for {
select {
case err := <-RunLimit(2, fn1, fn2, fn3, fn4):
// catch errors
case <-timeout:
// handle timeout
}
}
}
```
