Overview ¶

Package logo prints the brigada logo in a terminal: the banner (the Blackfire flame beside the pixel wordmark), the flame alone and the one-line form from docs/brand/cli, with the flame core in hi-vis orange where the terminal can show it, and the fallbacks docs/brand/README.md sets for no color, no UTF-8 and narrow terminals.

Render is pure: it prints what the given Caps allow. Detect reads the environment and the terminal to fill those Caps.

Functions ¶

func Render ¶

func Render(w io.Writer, form Form, caps Caps) error

Render writes form to w as caps allow:

without UTF-8, the banner and the mark print as ASCIIText when it fits, and nothing prints otherwise; the one-line form, which has no ASCII version, prints nothing;
narrower than MinWidth, the banner and the mark print as the one-line form;
with color, the flame core (coreCells in the banner and the mark) prints on a hi-vis background: the half blocks there keep the terminal's own foreground for the flame body and show orange in their other half, and the blanks turn orange; the ▙ of the one-line form prints in hi-vis; every other cell keeps the default foreground;
with NoColor, the texts print as they are, the core left blank.

func String ¶

func String(form Form, caps Caps) string

String returns what Render would write.

Types ¶

type Caps ¶

type Caps struct {
	// TTY is whether the output is a terminal. Render ignores it; callers
	// use it to leave the logo out of output that scripts read.
	TTY bool
	// Color is the color depth; NoColor prints no escape codes.
	Color Depth
	// UTF8 is false when the locale is not UTF-8 or TERM is dumb.
	UTF8 bool
	// Width is the terminal width in columns; 0 means unknown.
	Width int
}

Caps is what the output can show.

func Detect ¶

func Detect(w io.Writer) Caps

Detect fills Caps for output written to w, from the environment and, when w is a terminal, the terminal's size. Output that is not an *os.File on a terminal gets no color.

type Depth ¶

type Depth int

Depth is how many colors the terminal shows.

const (
	NoColor Depth = iota
	Color16
	Color256
	TrueColor
)

type Form ¶

type Form int

Form is the shape of the logo to print.

const (
	Banner Form = iota
	Mark
	OneLine
)
