banner clj/s

(banner m)

Returns a multi-line Figlet (ascii art) string with the provided :text option.

Intended to render a "single line" banner.

Can be optionally colorized with the :gradient option, using a small set of pre-defined gradients:

(banner {:text "Hello" :gradient-colors [:green :blue]})

Valid :gradient-color values:

[:green :blue], [:red :magenta], [:yellow :purple], [:orange :purple], [:cool :warm]

Valid :gradient-direction values:

:to-top, :to-bottom, :to-right, :to-left

Can be colorized solid with bling.core/bling:

(bling [:red (banner {:text "Hello"})])

Key	Pred	Description
:font	map?	Must be one of the fonts that ships with Bling: bling.fonts.ansi-shadow/ansi-shadow, bling.fonts.big-money.big-money/big-money , bling.fonts.big/big, bling.fonts.miniwi/miniwi, bling.fonts.drippy/drippy, or bling.fonts.isometric-1/isometric-1. Defaults to bling.fonts.ansi-shadow/ansi-shadow.
:text	string?	The text to set in the banner.
:font-weight	keyword?	If set to :bold, each subchar in figlet characters will be bolded. Only applies when a gradient is set.
:gradient-colors	vector?	Expects a vector of 2 keywords. Only the following color pairs are valid: [:green :blue], [:red :magenta], [:yellow :purple], [:orange :purple], [:cool :warm]. Only applies to terminal emulator printing
:gradient-direction	keyword?	Expects a keyword. Must be one of: :to-top, :to-bottom, :to-right, and :to-left. Only applies to terminal emulator printing
:gradient-shift	int?	If gradient is [:warm :cool] pair, this will shift the hue. 0-5. Defaults to 0.
:contrast	keyword?	If gradient is set, this will force an overall lighter or darker tone. Defaults to :medium. If the user has a BLING_MOOD env var set, it will default to :high in order to optimize contrast for the users terminal theme (light or dark)
:margin-top	int?	Amount of margin (in newlines) at top, outside banner. <br>Defaults to 1. Only applies to terminal emulator printing.
:margin-bottom	int?	Amount of margin (in newlines) at bottom, outside banner. <br>Defaults to 0. Only applies to terminal emulator printing.
:margin-left	int?	Amount of margin (in blank character spaces) at left, outside banner. <br>Defaults to 0. Only applies to terminal emulator printing.
:margin-right	int?	Amount of margin (in blank character spaces) at right, outside banner. <br>Defaults to 0. Only applies to terminal emulator printing.

(gradient-map gradient-colors direction gradient-shift contrast)

Expects a string as first argument representing a linear-gradient in standard css syntax: "to bottom, yellow, purple"

Expects a map (banner opts) as second argument, from which a value for the :contrast option may be provided.

If the user has BLING_MOOD env var set, the darker or lighter variant of the base color will be used, depending on the value of BLING_MOOD, which corresponds to the background terminal. The purpose is to lower or heighten the contrast.

Returns a map: {:gradient-range '(40 41 42 43 44 45) ;; <- range of sgr codes :gradient-orientation :vertical :vertical-gradient? true :horizontal-gradient? false }
