A powerful language integrated query library for Go. Inspired by Microsoft's LINQ.
- No dependencies: written in vanilla Go!
- Tested: 100.0% code coverage on all stable releases.
- Backwards compatibility: Your integration with the library will not be broken except major releases.
$ go get github.com/ahmetalpbalkan/go-linq
Example query: Find names of students over 18:
import . "github.com/ahmetalpbalkan/go-linq"
type Student struct {
id, age int
name string
}
over18Names, err := From(students)
.Where(func (s T) (bool,error){
return s.(*Student).age >= 18, nil
})
.Select(func (s T) (T,error){
return s.(*Student).name, nil
}).Results()Here is wiki:
