+# Haskell ESTGi Debugger
 
-A [Debug Adaptor Protocol](https://microsoft.github.io/debug-adapter-protocol) (DAP) library.
+This repository contains the components for Haskell debugging based on the Debug Adapter Protocol ([DAP](https://microsoft.github.io/debug-adapter-protocol)).
 
-This library can be used for constructing debug adaptors for any programming language.
+* [`dap/`](dap/): Language and backend independent simple DAP library
+* [`dap-estgi-server/`](dap-estgi-server/): DAP server for External STG Interpreter (DAP-ESTGi)
+* [`dap-estgi-vscode-extension/`](dap-estgi-vscode-extension/): VSCode extension to support Haskell debugging using DAP-ESTGi server
 
+## Overview
 
+The `dap-estgi-vscode-extension` turns VSCode into a Haskell debugger.
+VSCode offers a nice debugger UI while the debugger features are provided by the External STG Interpreter DAP Server.
 
+```mermaid
+flowchart LR
+    subgraph User Interface
+    A(VSCode) -.- |Plugin API| B(DAP ESTGi Extension)
+    end
+    B <-->|DAP via network| C(DAP ESTGi Server)
+    subgraph Debugger
+    C -.- |HS library API| D(External STG Interpreter)
+    end
 
+```
+
+The `dap-estgi-server` and `dap-estgi-vscode-extension` are application specific components, while the
+`dap` library is designed to be application independent to support any project that needs a simple DAP framework.
+
+## Setup
+
+1. VSCode setup  
+   Enable `allow breakpoints everywhere` option in VSCode settings.
+2. Run `dap-estgi-extension`
+   * Run: `(cd dap-estgi-vscode-extension ; npm install)`
+   * Open `dap-estgi-vscode-extension` folder by using the `Files/Open Folder` menu.
+   * Open the `src/extension.ts` file.
+   * Press F5 to run the extension in a new VSCode [Extension Development Host] window.
+3. Start `dap-estgi-server`  
+   `(cd dap-estgi-server ; stack run)`
+4. Compile debuggee program with GHC-WPC using stack  
+   * Add the following lines to debuggee's `stack.yaml`:
+     ```
+     # use custom ext-stg whole program compiler GHC
+     compiler:       ghc-9.2.7
+     compiler-check: match-exact
+     ghc-variant:    wpc
+     setup-info:
+       ghc:
+         linux64-custom-wpc-tinfo6:
+           9.2.7:
+             url: "https://github.com/grin-compiler/foundation-pak/releases/download/ghc-9.2.7/ghc-9.2.7-x86_64-unknown-linux.tar.xz"
+         macosx-custom-wpc:
+           9.2.7:
+             url: "https://github.com/grin-compiler/foundation-pak/releases/download/ghc-9.2.7/ghc-9.2.7-x86_64-apple-darwin.tar.xz"
+     ```
+   * Run: `stack build`
+5. Open debuggee program in VSCode [Extension Development Host]  
+   * Open debugge project folder by using the `Files/Open Folder` menu.
+   * Select the debug view on the side bar
+   * Click to `create a launch.json file`, then select `Haskell DAP ESTGi`
+   * Press F5 or the `Play` button to start debugging
+
