a Rich Text library for LÖVE

Post by Robin »

Update: For the latest version, go to GitHub.

Yet another idea, which will have to wait for implementation until that friggin laptop arrives.

Anyway, the idea is this: a library that knows how to draw text with different fonts, and how to insert images between them.

The lover would specify what to draw by doing something like:

Code: Select all

rt = rich.new("Hello, {font:big}world! {img:smile}", {big = bigFont, smile = smileyImage})
--or
rt = rich.new{"Hello, {font:big}world! {img:smile}", big = bigFont, smile = smileyImage})
--or
rt = rich.new{"Hello, {big}world! {smile}", big = bigFont, smile = smileyImage}
(I'm not sure yet which is better.)

Then one would do:

Code: Select all

function love.draw()
    rt:draw()
end
rich.new() will probably start by rendering to a Framebuffer, because such text is probably static while quite expensive to generate.

I'm also planning on having it word-wrap and handle NPO2 images gracefully.

What do you think? Useful or useless?

EDIT: closed poll. Popular vote decided RT to be licensed zlib.

Yes please! I've had to do stuff like this manually oh-so-many times, and it's a freaking pain.

Good. You (and other lovers who'd like to use this) could help by listing requirements and such while I wait for my new laptop to arrive. ;)

Optional parameters for specifying the width and height of the image(s), since you often have to pad for Po2-ness, is the first thing that comes to mind.

Ah, yes, I had that in mind as well.

Here's the idea: you can specify an image as, well, an image:

Code: Select all

... keyz = love.graphics.newImage("images/keys/z.png"), ...
or as a table:

Code: Select all

... keyz = {love.graphics.newImage("images/keys/z.png"), width = 36, height = 26}, ... -- where that image is padded in the image editor to 64x32
(or perhaps even with a string:

Code: Select all

... keyz = "images/keys/z.png", ...
)

The big idea is, that if you don't manually specify a width and height, the library will autopad the image itself, remember the original dimensions, and use those for drawing.

If we can specify dimensions, we should also have Quad support.

Code: Select all

rt = rich.new("Hello, {font:big}world! {img:smile quad:myQuad}", {big = bigFont, smile = smileyImage, myQuad = whateverQuad})
Also, may I propose either HTML or BBCode as the syntax?

Good idea. However, I don't think it would be specified in-string, but rather as something like:

Code: Select all

rt = rich.new("Hello, {font:big}world! {img:smile}", {big = bigFont, smile = {smileyImage, quad = whateverQuad}})
This to keep the strings relatively easy to parse.

You may. Syntax is of course subject to change (since I haven't written a damned line for it yet), but I think I might actually prefer the BBCode-inspired "tags", since [] do not require the shift key to type them (as opposed to {} and <>, at least on my keyboard).

And another thing: I think the font: and img: prefixes will be dropped, since their type can be inferred.

Example:

Code: Select all

rt = rich.new("Hello, [big]world! [smile]", {big = bigFont, smile = {smileyImage, quad = whateverQuad}})

Instead they require Ctrl + Alt or Alt Gr. Wee! :P (Don't really care either way)

Heh, as soon as I saw you replied, I thought "bartbes is going to burn this idea to the ground, showing three different reasons why it is both unneccesary and destined for failure". (Actually I was waiting for this since I wrote the OP.) :crazy:

But anyway, you reminded me of something rather important I forgot: the alternate alternate syntax I had in mind:

Code: Select all

rt = rich.new("Hello, ", bigFont, "world! ", {smileyImage, quad = someQuad})
... only this may not be feasible, since I intend to add optional extra parameters for wrapping and such.
