Functions ¶

func BindFlagSet ¶

func BindFlagSet(wo *Options) *pflag.FlagSet

func Main ¶

func Main(options Options) error

Main is the kickoff for the wc program. so it can be compiled stand alone or as a subcommand runs as many workers as CPUs. this probably should be tunable at compile time

func ReadFile ¶

func ReadFile(options Options, fnChan <-chan string, resChan chan<- Results, errChan chan<- error, wg *sync.WaitGroup)

ReadFile from a chan and stream out results. It was a closure over what the arguments are, but I want to pull it out to test

Types ¶

type Options ¶

type Options struct {
	Bytes, Characters, Newlines, Words, Longest bool

	NFlag uint
	Files []string
}

func (Options) GetBool ¶

func (wo Options) GetBool(flag string) bool

type Results ¶

type Results struct {
	Bytes, Characters, Newlines, Words, Longest uint

	Filename string
}

Results are the totals for output

func WordCount ¶

func WordCount(opts Options, in io.Reader) (Results, error)

func (Results) GetMax ¶

func (r Results) GetMax(options Options) (max uint)

GetMax number (that isn't line) from this resultset for use in max line length parameter

type ResultsSet ¶

type ResultsSet struct {
	MaxNumber uint

	Results []Results
}

func (ResultsSet) Printf ¶

func (rs ResultsSet) Printf(options Options) string

Printf prints all results based on format options

func (ResultsSet) String ¶

func (rs ResultsSet) String() string
