Market stores current market information displayed in the top three lines of the screen. The market data is fetched and parsed from the HTML page above.

func NewMarket 

func NewMarket(vendor APISourceType) *Market

Returns new initialized Market struct.

func (*Market) Fetch 

func (market *Market) Fetch() (self *Market)

Fetch downloads HTML page from the 'marketURL', parses it, and stores resulting data in internal hashes. If download or data parsing fails Fetch populates 'market.errors'.

func (*Market) FetchQQ 

func (market *Market) FetchQQ() (self *Market)

Fetch downloads HTML page from the 'marketURL', parses it, and stores resulting data in internal hashes. If download or data parsing fails Fetch populates 'market.errors'.

func (*Market) FetchYahoo

	RightAligned bool              // True when the string is right aligned.
	// contains filtered or unexported fields
}

Markup implements some minimalistic text formatting conventions that get translated to Termbox colors and attributes. To colorize a string wrap it in <color-name>...</> tags. Unlike HTML each tag sets a new color whereas the </> tag changes color back to default. For example:

<green>Hello, <red>world!</>

The color tags could be combined with the attributes: <b>...</b> for bold, <u>...</u> for underline, and <r>...</r> for reverse. Unlike colors the attributes require matching closing tag.

The <right>...</right> tag is used to right align the enclosed string (ex. when displaying current time in the upper right corner).

func NewMarkup 

func NewMarkup() *Markup

Creates markup to define tag to Termbox translation rules and store default colors and column alignments.

func (*Markup) IsTag 

func (markup *Markup) IsTag(str string) bool

func (*Markup) Tokenize 

func (markup *Markup) Tokenize(str string) []string

Tokenize works just like strings.Split() except the resulting array includes the delimiters. For example, the "<green>Hello, <red>world!</>" string when tokenized by tags produces the following: 

[0] "<green>"
[1] "Hello, "
[2] "<red>"
[3] "world!"
[4] "</>"

type PKData 

type PKData struct {
	BuyBig    float64 //0: 买盘大单

	Tickers       []string // List of stock tickers to display.
	MarketRefresh int      // Time interval to refresh market data.
	QuotesRefresh int      // Time interval to refresh stock quotes.
	SortColumn    int      // Column number by which we sort stock quotes.
	Ascending     bool     // True when sort order is ascending.
	Grouped       bool     // True when stocks are grouped by advancing/declining.
