Usage

Blipgloss takes an expressive, declarative approach to terminal rendering. Users familiar with CSS will feel at home with Blipgloss.

import { NewStyle } from 'blipgloss'

const style = NewStyle()
  .Bold(true)
  .Foreground("#FAFAFA")
  .Background("#7D56F4")
  .PaddingTop(2)
  .PaddingLeft(4)
  .Width(22)

console.log(style.Render("Hello, bun."))

Colors

Blipgloss supports the following color profiles:

ANSI 16 colors (4-bit)

Background("5")  // magenta
Background("9")  // red
Background("12") // light blue

ANSI 256 colors (8-bit)

Background("86")  // aqua
Background("201") // hot pink
Background("202") // orange

True Color (16,777,216 colors; 24-bit)

Background("#0000FF") // good ol' 100% blue
Background("#04B575") // a green
Background("#3C3C3C") // a dark gray

...as well as a 1-bit Ascii profile, which is black and white only.

The terminal's color profile will be automatically detected, and colors outside the gamut of the current palette will be automatically coerced to their closest available value.

Inline Formatting

Blipgloss supports the usual ANSI text formatting options:

const style = NewStyle()
  .Bold(true)
  .Italic(true)
  .Faint(true)
  .Blink(true)
  .Strikethrough(true)
  .Underline(true)
  .Reverse(true)

Block-Level Formatting

Blipgloss also supports rules for block-level formatting:

// Padding
const style = NewStyle()
  .PaddingTop(2)
  .PaddingRight(4)
  .PaddingBottom(2)
  .PaddingLeft(4)

// Margins
const style = NewStyle()
  .MarginTop(2)
  .MarginRight(4)
  .MarginBottom(2)
  .MarginLeft(4)

There is also shorthand syntax for margins and padding, which follows the same format as CSS:

Aligning Text

TODO

Width and Height

Setting a minimum width and height is simple and straightforward.

const str = lipgloss.NewStyle()
  .Width(24)
  .Height(32)
  .Foreground("63")
  .Render("What’s for lunch?")

Rendering

Generally, you just call the Render(string) method:

console.log(NewStyle().Bold(true).Render("Hello, bun."))
