Functions

func DoConcurrently

func DoConcurrently[T any, errorT any](
	work func(c chan T, errorChan chan errorT),
	handleError func(e errorT),
	c chan T,
	numWorkers int,
)

DoConcurrently is a simple worker pool implementation. It starts up numWorkers goroutines and, in each, calls `work(c, errorChan)`. Any errors that `work` writes to errorChan are passed to handleError(). DoConcurrently returns when all the workers have exited.

func FormatTime

func FormatTime(t time.Time) string

func Message

func Message(format string, args ...any)

Message prepends the program name and appends a newline to whatever message is passed in, then writes it standard output.

func Prompt

func Prompt(prompt string) bool

Prompt asks a yes/no question. It appends ` y/n ` to the prompt.

func RemovePrefix

func RemovePrefix(key string, prefix string) string

RemovePrefix removes prefix/ from the beginning of a key that is known to start with prefix/.

func SortedKeys

func SortedKeys[T any](m map[string]T) []string
