This is a modern, GitHub-optimized path to mastering Haskell, designed to grow your skills **and** your profile ⭐.\n\nWhether 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.\n\n---\n\n## ✨ Why This Course?\n\n-   ✅ Beginner-friendly explanations\n-   🔍 Real-world code examples\n-   🔁 Step-by-step challenges\n-   🌱 Build incrementally- one concept at a time\n-   🌐 Grow your GitHub with visible progress\n\n---\n\n\u003cbr/\u003e\n\n# 🧠 How This Course Works\n\n## 1. 📖 Learn a Concept\n\n-   Short, clear explanations\n-   💡 Minimal but focused code examples\n-   🎨 Visuals and edge cases explained\n\n## 2. 🏋️‍♂️ Try It Yourself\n\n-   Solve challenges in each lesson folder\n-   ⬆️ Push your work to GitHub\n-   📝 Add notes on what confused you\n\n## 3. 🧩 Level Up Over Time\n\n-   Each module builds on the last\n-   🧠 Develop intuition, not just syntax\n\n## 4. 🗒️ Document What You Learn\n\n-   Use the built-in note system (or create your own)\n-   🚩 Keep track of mistakes, gotchas, and \"aha\" moments\n\n\u003cbr/\u003e\n\n---\n\n\u003cbr/\u003e\n\n# 📝 Reading Notes and Lessons in VS Code\n\nAll lessons and notes use **Markdown (`.md`) files** for a clean, readable experience in VS Code.\n\n\u003e 💡 **Tip:**\n\u003e\n\u003e -   Right-click any `.md` file (like `README.md`, `01-Fundamentals.md`, etc.) and choose **“Open Preview”**\n\u003e -   Or use the shortcut:\n\u003e     -   **Mac:** `Cmd + Shift + V`\n\u003e     -   **Windows/Linux:** `Ctrl + Shift + V`\n\nThis opens a styled, easy-to-read view, perfect for:\n\n| 📚 What?              | 📝 File(s)      |\n| --------------------- | --------------- |\n| Lecture explanations  | `/content/*.md` |\n| Your personal notes   | `/notes/*.md`   |\n| Exercise walkthroughs | lesson folders  |\n\nYou can also **split the editor** and open the preview side-by-side with the text for even better workflow!\n\n\u003cbr/\u003e\n\n---\n\n\u003cbr/\u003e\n\n# ⚙️ Getting Set Up\n\n### 📦 Step 1: Install GHC, Cabal \u0026 Stack\n\n**Install via [GHCup](https://www.haskell.org/ghcup/):**\n\n```bash\ncurl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh\n```\n\nThis will install:\n\n-   `ghc` → The Haskell compiler\n-   `cabal` → Standard Haskell build tool\n-   `stack` → Optional alternative build tool (you may not need it, but it's good to have)\n\nAfter installation, **restart your terminal**, then check your install:\n\n```bash\nghc --version\ncabal --version\nstack --version  # optional\n```\n\n✅ If you see version numbers, your installation is successful.\n\n---\n\n### 💻 Step 2: Install VS Code + Extensions\n\nDownload [Visual Studio Code](https://code.visualstudio.com/) if you don’t have it.\n\n**Recommended Extensions:**\n\n| Extension                      | Publisher   | Why                                                                 |\n| ------------------------------ | ----------- | ------------------------------------------------------------------- |\n| 🟣 Haskell                     | Haskell     | Full support: errors, warnings, type hints, go-to-definition (HLS). |\n| 🎨 Haskell Syntax Highlighting | Justus Adam | Adds proper syntax coloring for `.hs` files.                        |\n\n#### ⚠️ What you don't need:\n\n-   Live Server or Code Runner → Not needed for Haskell\n-   Old/unmaintained Haskell extensions → stick to the two above\n\n\u003cbr/\u003e\n\nAfter installing the Haskell extension, VS Code will prompt you to install **Haskell Language Server (HLS)** if it isn’t already set up.  \n👉 Accept that prompt.\n\nWith both extensions installed, you’ll get syntax highlighting + smart Haskell editing.\n\n---\n\n### ✅ Step 3: Clone the Course Repo\n\nThe course is pre-structured, i.e. you don’t need to create a new project. Just clone and open it:\n\n```bash\ngit clone https://github.com/AskewCow/haskell-by-doing\ncd haskell-course\ncode . # Opens folder in vsc\n```\n\nYou’re ready to go! 🎉 Start with `01-Fundamentals/content`\n\n---\n\n### 🧪 Optional: Test That VS Code Works\n\nOpen any `.hs` file in VS Code and make sure you see:\n\n-   Autocompletion\n-   Type info when hovering over expressions\n-   Inline error messages (if something’s wrong)\n-   Haskell-specific color syntax\n\nIf all of those are working, then HLS is active and everything is set up properly.\n\n\u003cbr/\u003e\n\n---\n\n# 🚀 Ready to Start Your Haskell Journey?\n\n\u003cdiv align=\"center\"\u003e\n    \n**You're all set!** 🎉 Dive into the lessons, experiment, and don't forget to jot down your discoveries and mistakes in your notes.\n\n\u003cimg src=\"https://img.shields.io/badge/⭐-Star%20this%20repo%20if%20it%20helped%20you!-FFD700?style=for-the-badge\u0026logo=github\u0026logoColor=white\" alt=\"Star this repo\"/\u003e\n\n\u003cbr/\u003e\n\n\u003ca href=\"https://github.com/AskewCow/haskell-by-doing/stargazers\"\u003e\n    \u003cimg src=\"https://img.shields.io/github/stars/AskewCow/haskell-by-doing?style=social\u0026label=Star\" alt=\"GitHub stars\"/\u003e\n\u003c/a\u003e\n\n\u003cbr/\u003e\n\n**Happy Haskell-ing!** 🐏✨\n\n\u003c/div\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faskewcow%2Fhaskell-by-doing","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Faskewcow%2Fhaskell-by-doing","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faskewcow%2Fhaskell-by-doing/lists"}
