sorty golang library to allow sorting slices of maps easy.
package main
import (
"fmt"
"github.com/coryb/sorty"
"os"
)
func main() {
// sort maps first in ascending order on the "foo" key
// then in decending order on the "bar" key
s := NewSorter().ByKeys([]string{
"+foo",
"-bar",
})
data := []map[string]interface{}{
{"foo": "abc", "bar": 890},
{"foo": "xyz", "bar": 123},
{"foo": "def", "bar": 456},
{"foo": "mno", "bar": 789},
{"foo": "def", "bar": 789},
}
s.Sort(data)
// Data will now look like:
// []map[string]interface{}{
// {"foo": "abc", "bar": 890},
// {"foo": "def", "bar": 789},
// {"foo": "def", "bar": 456},
// {"foo": "mno", "bar": 789},
// {"foo": "xyz", "bar": 123},
// }
}I found myself writing several tools that needed to pull large json documents from rest apis. The rest apis did not always return data in a sorted order or in a sorted order that was not what I needed to process/display them in. I found it tedious to write the sort.Interface for sorting on multiple keys so I created an abstraction. I dont expect it do be very performant, but I am typically sorting dozens of items instead of millions.
