README.md

richtext is a text and image formatting library for the LÖVE framework.

usage

local rich = require 'richtext'

rt = rich:new{"Hello {green}world{red}, {smile} {big}Big text.", 200,
              black = {0, 0, 0}, green = {0, 255, 0},
              big = love.graphics.newFont(20), red = {255, 0, 0},
              smile = love.graphics.newImage('smile.png')}

function love.draw()
    rt:draw(10, 10)
end

or

local rich = require 'richtext'

local initialcolor = {255,255,255,255}

local textmacros = {}
textmacros.black = {0, 0, 0}
textmacros.green = {0, 255, 0}
textmacros.red = {255, 0, 0}
textmacros.big = love.graphics.newFont(20)
textmacros['smile.png'] = love.graphics.newImage('smile.png')

rt = rich:new( {"Hello {green}world{red}, {smile} {big}Big text.", 200, textmacros }, initialcolor )

function love.draw()
    rt:draw(10, 10)
end

features

  • automatically pads images to PO2, without any alignment problems

  • wraps words and images together

current issues

  • richtext is still not well-tested

  • word wrapping might not be optimally done, because it always splits the first word, which might lead to a lot of splitting (the end result is fine, though)

  • words keep their final space in wrapping, which may cause words to be wrapped just a bit too soon

  • any initial text color (other than white) has to be specified manually by starting text
