SimpleWriter comes with several built-in extensions:
- Dark Mode - Switch to a dark theme for night-time writing
- Focus Mode - Fade out everything except the current paragraph
- Pomodoro Timer - Built-in writing timer with work/break cycles
- Click the extension icon in the top-right corner
- Select the "Add New" tab
- Click "Choose File" and select an extension file (.js)
- Click "Upload Extension"
- Enable the extension using the toggle switch
These extensions are available in the extensions folder:
- Spell Check - Basic spell checking with suggestions
- Enhanced Spell Check - Multi-language spell checking using Typo.js
- [More extensions coming soon!]
You can create custom extensions to add features to SimpleWriter. Here's a basic template:
(function(env) {
env.registerExtension({
id: 'your-extension-id',
name: 'Your Extension Name',
description: 'Description of what your extension does',
enabled: false,
enabledByDefault: false,
// Lifecycle methods
onEnable: function() {
// Code that runs when the extension is enabled
},
onDisable: function() {
// Code that runs when the extension is disabled
},
// Extension hooks
hooks: {
// Hook into app events
onEditorInput: function(editor) {
// Process editor input
return editor;
},
onChapterLoad: function(editor, chapter) {
// Do something when a chapter is loaded
return editor;
}
}
});
})(env);See the Extension Development Guide for more detailed information.
