func BuildFullURL ¶

func BuildFullURL(host string, path string, query map[string]string) (string, error)

BuildFullURL builds a complete URL string in the format host/path?query, where query's keys and values will be formatted as k=v. Returns an util.MalformedURLError if the given URL can't be parsed. This function is a (very simplified version of url.URL.String().

func CleanSlashes ¶

func CleanSlashes(url string) (string, error)

CleanSlashes removes extraneous slashes (like nexus.com///something), which Nexus' API doesn't recognize as valid. Returns an util.MalformedURLError if the given URL can't be parsed.

func MapDiff ¶

func MapDiff(expected map[string]string, actual map[string]string) (diff []string, onlyExpected []string, onlyActual []string)

MapDiff calculates the difference between two maps. It returns three values:

* diff: a slice of strings, holding the keys in both with different values;

* onlyExpected: a slice of keys only in expected;

* onlyActual: a slice of keys only in actual.

When the maps are equal, all three slices will be empty.

package main

import (
	"fmt"

	"sbrubbles.org/go/nexus/util"
)

func main() {
	expected := map[string]string{"a": "a", "b": "b"}
	actual := map[string]string{"a": "aaaa", "c": "c"}

	diff, onlyExpected, onlyActual := util.MapDiff(expected, actual)
	fmt.Println(diff)         // ["a"]
	fmt.Println(onlyExpected) // ["b"]
	fmt.Println(onlyActual)   // ["c"]

	diff, onlyExpected, onlyActual = util.MapDiff(expected, expected)
	fmt.Println(diff)         // []
	fmt.Println(onlyExpected) // []
	fmt.Println(onlyActual)   // []
}

Output:
