# 🐏 Learn Haskell - A GitHub-Driven Learning Course
Welcome to the **Haskell by Doing** course! This is a modern, GitHub-optimized path to mastering Haskell, designed to grow your skills **and** your profile ⭐.
Whether you're just starting out or brushing up, this course will walk you through functional programming concepts using a structured, visual, and hands-on approach.
---
## ✨ Why This Course?
- ✅ Beginner-friendly explanations
- 🔍 Real-world code examples
- 🔁 Step-by-step challenges
- 🌱 Build incrementally- one concept at a time
- 🌐 Grow your GitHub with visible progress
---
# 🧠 How This Course Works
## 1. 📖 Learn a Concept
- Short, clear explanations
- 💡 Minimal but focused code examples
- 🎨 Visuals and edge cases explained
## 2. 🏋️♂️ Try It Yourself
- Solve challenges in each lesson folder
- ⬆️ Push your work to GitHub
- 📝 Add notes on what confused you
## 3. 🧩 Level Up Over Time
- Each module builds on the last
- 🧠 Develop intuition, not just syntax
## 4. 🗒️ Document What You Learn
- Use the built-in note system (or create your own)
- 🚩 Keep track of mistakes, gotchas, and "aha" moments

# 📝 Reading Notes and Lessons in VS Code
All lessons and notes use **Markdown (`.md`) files** for a clean, readable experience in VS Code.
> 💡 **Tip:**
>
> - Right-click any `.md` file (like `README.md`, `01-Fundamentals.md`, etc.) and choose **“Open Preview”**
> - Or use the shortcut:
> - **Mac:** `Cmd + Shift + V`
> - **Windows/Linux:** `Ctrl + Shift + V`
This opens a styled, easy-to-read view, perfect for:
| 📚 What? | 📝 File(s) |
| --------------------- | --------------- |
| Lecture explanations | `/content/*.md` |
| Your personal notes | `/notes/*.md` |
| Exercise walkthroughs | lesson folders |
You can also **split the editor** and open the preview side-by-side with the text for even better workflow!

# ⚙️ Getting Set Up
### 📦 Step 1: Install GHC, Cabal & Stack
**Install via [GHCup](https://www.haskell.org/ghcup/):**
```bash
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
```
This will install:
- `ghc` → The Haskell compiler
- `cabal` → Standard Haskell build tool
- `stack` → Optional alternative build tool (you may not need it, but it's good to have)
After installation, **restart your terminal**, then check your install:
```bash
ghc --version
cabal --version
stack --version # optional
```
✅ If you see version numbers, your installation is successful.
---
### 💻 Step 2: Install VS Code + Extensions
Download [Visual Studio Code](https://code.visualstudio.com/) if you don’t have it.
**Recommended Extensions:**
| Extension | Publisher | Why |
| ------------------------------ | ----------- | ------------------------------------------------------------------- |
| 🟣 Haskell | Haskell | Full support: errors, warnings, type hints, go-to-definition (HLS). |
| 🎨 Haskell Syntax Highlighting | Justus Adam | Adds proper syntax coloring for `.hs` files. |
#### ⚠️ What you don't need:
- Live Server or Code Runner → Not needed for Haskell
- Old/unmaintained Haskell extensions → stick to the two above
After installing the Haskell extension, VS Code will prompt you to install **Haskell Language Server (HLS)** if it isn’t already set up.
👉 Accept that prompt.
With both extensions installed, you’ll get syntax highlighting + smart Haskell editing.
---
### ✅ Step 3: Clone the Course Repo
The course is pre-structured, i.e. you don’t need to create a new project. Just clone and open it:
```bash
git clone https://github.com/AskewCow/haskell-by-doing
cd haskell-course
code . # Opens folder in vsc
```
You’re ready to go! 🎉 Start with `01-Fundamentals/content`
---
### 🧪 Optional: Test That VS Code Works
Open any `.hs` file in VS Code and make sure you see:
- Autocompletion
- Type info when hovering over expressions
- Inline error messages (if something’s wrong)
- Haskell-specific color syntax
If all of those are working, then HLS is active and everything is set up properly.
