Pasting the wrong thing can expose sensitive information. #### Export Output to a File If you want to export the console output, simply right click anywhere on the console and click **Save as..**  ## Development This section details the setup of a basic developmentment environment. ### Getting Started **System Requirements** * [Node.js][nodejs] v20 --- **Clone and Install Dependencies** ```console > git clone https://github.com/dscalzi/HeliosLauncher.git > cd HeliosLauncher > npm install ``` --- **Launch Application** ```console > npm start ``` --- **Build Installers** To build for your current platform. ```console > npm run dist ``` Build for a specific platform. | Platform | Command | | ----------- | -------------------- | | Windows x64 | `npm run dist:win` | | macOS | `npm run dist:mac` | | Linux x64 | `npm run dist:linux` | Builds for macOS may not work on Windows/Linux and vice-versa. --- ### ExtraFileVerification The Extra File Verification System ExtraFileVerification prevents the use of unapproved mods in HeliosLauncher by verifying the integrity of each mod from the distribution, blocking unauthorized changes, and ensuring a secure, reliable gaming experience. **How to active this ?** ```console > npm run extraverif ``` ``` Would you like to activate extra file verification? (yes/no): yes Would you like to activate debug mode? (yes/no): yes Would you like to hide or block the menu? (hide/block): block Extra file verification activated. Menu blocked. ``` You can choose whether extra file verification hides the mod category or blocks interaction with the drop-in mod. --- ### Visual Studio Code All development of the launcher should be done using [Visual Studio Code][vscode]. Paste the following into `.vscode/launch.json` ```JSON { "version": "0.2.0", "configurations": [ { "name": "Debug Main Process", "type": "node", "request": "launch", "cwd": "${workspaceFolder}", "program": "${workspaceFolder}/node_modules/electron/cli.js", "args" : ["."], "outputCapture": "std" }, { "name": "Debug Renderer Process", "type": "chrome", "request": "launch", "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron", "windows": { "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd" }, "runtimeArgs": [ "${workspaceFolder}/.", "--remote-debugging-port=9222" ], "webRoot": "${workspaceFolder}" } ] } ``` This adds two debug configurations. #### Debug Main Process This allows you to debug Electron's [main process][mainprocess]. You can debug scripts in the [renderer process][rendererprocess] by opening the DevTools Window. #### Debug Renderer Process This allows you to debug Electron's [renderer process][rendererprocess]. This requires you to install the [Debugger for Chrome][chromedebugger] extension. Note that you **cannot** open the DevTools window while using this debug configuration. Chromium only allows one debugger, opening another will crash the program. --- ### Note on Third-Party Usage Please give credit to the original author and provide a link to the original source.
