Types

type FlagTokenizer

	BooleanFlags sets.TinySet[string]
	Tokenized    map[string]string
	Actions      []string
}

FlagTokenizer holds the names of the boolean flags and uses them the tokenize the input args into args and actions. Actions are args that are not flags.

After calling FlagTokenizer.TokenizeFlags the Tokenized and Action fields will be initialized.

func NewFlagTokenizer

func NewFlagTokenizer(booleanFlags ...string) *FlagTokenizer

NewFlagTokenizer creates a new FlagTokenizer from a list of boolean flag names

func (*FlagTokenizer) TokenizeFlags

func (ft *FlagTokenizer) TokenizeFlags(args []string)
