Roblox Console

-- Run in Roblox Studio Console
local HttpService = game:GetService("HttpService"); 
local ReplicatedStorage = game:GetService("ReplicatedStorage");
local LastValue = HttpService.HttpEnabled

HttpService.HttpEnabled = true

local ChalkModule = Instance.new("ModuleScript");
ChalkModule.Name = "Chalk";
ChalkModule.Parent = ReplicatedStorage;

local Request = HttpService:RequestAsync({
    Url = "https://raw.githubusercontent.com/Perthys/chalk/main/source/main.lua";
    Method = "GET";
});

HttpService.HttpEnabled = LastValue

if Request.Success and Request.StatusCode == 200 then
    ChalkModule.Source = Request.Body

    print("Successfully installed Chalk module. At:", ChalkModule);
else
    error("Failed to install Chalk module.");

Usage

Blue Text Example

Chalk has a very simple but powerful API

local ReplicatedStorage = game:GetService("ReplicatedStorage");
local Chalk = require(ReplicatedStorage:WaitForChild("Chalk"));

local TextBox = script.Parent;

TextBox.Text = Chalk.blue('Hello world!')

Multi String Example

Chalk comes with an easy to use composable API where you just chain and nest the styles you want.

local ReplicatedStorage = game:GetService("ReplicatedStorage");
local Chalk = require(ReplicatedStorage:WaitForChild("Chalk"));

local TextBox = script.Parent; TextBox.RichText = true;

local function Update(String) TextBox.Text = String; task.wait(1); end

Update(Chalk.blue("Hello") .. 'World' .. Chalk.red("!"))
Update(Chalk.blue.bold("Hello world!"))
Update(Chalk.blue("Hello", "World!", "Foo", "bar", "biz", "baz"))
Update(Chalk.red("Hello", Chalk.underline("world") .. "!"))
Update(Chalk.green("I am a green line " .. Chalk.blue.underline.bold("with a blue substring") .. " that becomes green again!"))

Update(("CPU: %s \nRAM: %s \nDISK: %s"):format(Chalk.red("90%"), Chalk.green("40%"), Chalk.yellow("70%")))

Update(Chalk.color(123, 45, 67).underline("Underlined reddish color"))
Update(Chalk.color("#DEADED").bold("Bold gray!"))

Theme Creation

Easily define your own themes

local ReplicatedStorage = game:GetService("ReplicatedStorage");
local Chalk = require(ReplicatedStorage:WaitForChild("Chalk"));

local TextBox = script.Parent; TextBox.RichText = true;

local error = Chalk.bold.red;
local warning = Chalk.color("#FFA500");

local function Update(String) TextBox.Text = String; task.wait(1); end

Update(error("Error!")) 
Update(warning("Warning!"));

Take advantage of string substitution:

local ReplicatedStorage = game:GetService("ReplicatedStorage");
local Chalk = require(ReplicatedStorage:WaitForChild("Chalk"));

local TextBox = script.Parent; TextBox.RichText = true;

local function Update(String) TextBox.Text = String; task.wait(1); end

local Name = "Builderman";
Update(Chalk.green(("Hello %s"):format(Name)))

API

Chalk Syntax and Typing

Example:

chalk[ ArgumentStyle ] -> (...: StyleArgs) -> chalk(...: string)
chalk.size(40)("test");

chalk[ ModifierStyle ] -> chalk(...: string)
chalk.bold("test");

chalk[ ArgumentStyle ] -> (...: StyleArgs) -> chalk[ ArgumentStyle ] -> (...) -> chalk(...: string)
chalk.size(40).color(40,20,30)("test");

chalk[ ArgumentStyle ] -> (...: StyleArgs) -> chalk[ ModifierStyle ] -> chalk(...: string)
chalk.size(40).bold("test");

chalk[ ModifierStyle ] -> chalk[ ModifierStyle ] -> chalk(...: string)
chalk.red.bold("test");

chalk[ ModifierStyle ] -> chalk[ ArgumentStyle ] -> (...: StyleArgs) -> chalk(...: string)
chalk.red.size(40)("test");

Chain styles calls the last Style as a method with a string argument.
Order doesn't matter, and earlier Styles take priority in case of a conflict.
This simply means that chalk.red.yellow.green is equivalent to chalk.red.

• Chalk.weight([<Weight>]) - Set the font weight (String)
• Chalk.transparency([<Transparency>]) - Set the transparency of the text (Number 0-1)
• Chalk.stroke({Color = [<Color>], Joins = [<Joins>], Thickness = [<Thickness>], Transparency = [<Transparency>]}) - Define stroke properties: color (Color3), joins (String), thickness (Number), and transparency (Number)

• hex - Example: chalk.color('#FF8800').bold('Orange!')
• Color3 - Example: chalk.color(Color3.fromRGB(255, 136, 0)).bold("Orange")
• BrickColor - Example chalk["Earth orange"]

Origin story

I wanted to make the npm package chalk for roblox luau richtext because I really did not want to do styling manually.

Comments

• ROBLOX PLEASE ENABLE RICH TEXT TO CONSOLE TEXT OBJECTS, you can make a interface with LogService so print/warn/error can still output raw text.
• If roblox adds support for background text color directly with richtext I will also add support.
• If you have any issues or suggestions best way to contact me would be through discord Perthys#0.
