Functions

func InterfaceSlice

func InterfaceSlice(slice interface{}) []interface{}

Needed because Go won't let us cast from []FooProto --> []googleProto.Message https://stackoverflow.com/questions/12753805/type-converting-slices-of-interfaces

func ReadCsvFile

func ReadCsvFile(filePath string) [][]string

func ReadFile

func ReadFile(filePath string) string

func ReadFileLines

func ReadFileLines(filePath string) []string

func ReadFileLinesOrNil

func ReadFileLinesOrNil(filePath string) []string

func ReadMap

func ReadMap(filePath string) map[string]string

func ReadMapOrNil

func ReadMapOrNil(filePath string) map[string]string

func ReadWeb

func ReadWeb(url string) (string, error)

Fetches web results a single url, and returns the page contents as a string.

func ReadWebMulti

func ReadWebMulti(urls []string) []string

Fetches web results from all the given urls, and returns a parallel array of page contents.

func ReadWebMultiMap

func ReadWebMultiMap[K comparable](keys []K, keyToUrl func(K) string) map[K]string

Like ReadWebMulti, but uses a lambda function for converting keys --> urls and returns a map of keys to web contents.

func ReadWebRequired

func ReadWebRequired(url string) string

func WriteFile

func WriteFile(filePath string, content string)

func WriteFileLines

func WriteFileLines(filePath string, lines []string)

func WriteMap

func WriteMap(filePath string, contents map[string]string)

func WriteMapCustomSort

func WriteMapCustomSort(filePath string, contents map[string]string, sortFunc func(a, b string) bool)

func WriteMapSortByIntKey

func WriteMapSortByIntKey(filePath string, contents map[string]string)

func WriteProtoArrayToBuilder

func WriteProtoArrayToBuilder(arrInterface interface{}, builder *strings.Builder, name string)
