Monaco Collaborative Extensions\n[![Build Status](https://travis-ci.org/convergencelabs/monaco-collab-ext.svg?branch=master)](https://travis-ci.org/convergencelabs/monaco-collab-ext)\n\nEnhances the [Monaco Editor](https://github.com/Microsoft/monaco-editor) by adding the ability to render cues about what remote users are doing in the system.\n\n![demo graphic](./docs/demo.gif \"Shared Cursors and Selections\")\n\n## Installation\n\nInstall package with NPM and add it to your development dependencies:\n\n```npm install --save-dev @convergencelabs/monaco-collab-ext```\n\n## Demo\nGo [here](https://examples.convergence.io/examples/monaco/) to see a live demo of multiple cursors, multiple selections, and remote scrollbars (Visit on multiple browsers, or even better, point a friend to it too).  This uses [Convergence](https://convergence.io) to handle the synchronization of data and user actions. \n\n## Usage\n\n### RemoteCursorManager\nThe RemoteCursorManager allows you to easily render the cursors of other users\nworking in the same document.  The cursor position can be represented as either\na single linear index or as a 2-dimensional position in the form of\n```{lineNumber: 0, column: 10}```.\n\n```JavaScript\nconst editor = monaco.editor.create(document.getElementById(\"editor\"), {\n  value: \"function helloWorld = () =\u003e { console.log('hello world!')\",\n  theme: \"vs-dark'\",\n  language: 'javascript'\n});\n\nconst remoteCursorManager = new MonacoCollabExt.RemoteCursorManager({\n  editor: editor,\n  tooltips: true,\n  tooltipDuration: 2\n});\n\nconst cursor = remoteCursorManager.addCursor(\"jDoe\", \"blue\", \"John Doe\");\n\n// Set the position of the cursor.\ncursor.setOffset(4);\n\n// Hide the cursor\ncursor.hide();\n\n// Show the cursor\ncursor.show();\n\n// Remove the cursor.\ncursor.dispose();\n```\n\n### RemoteSelectionManager\nThe RemoteSelectionManager allows you to easily render the selection of other\nusers working in the same document.\n\n```JavaScript\nconst editor = monaco.editor.create(document.getElementById(\"editor\"), {\n  value: \"function helloWorld = () =\u003e { console.log('hello world!')\",\n  theme: \"vs-dark'\",\n  language: 'javascript'\n});\n\nconst remoteSelectionManager = new MonacoCollabExt.RemoteSelectionManager({editor: editor});\n\nconst selection = remoteSelectionManager.addSelection(\"jDoe\", \"blue\");\n\n// Set the range of the selection using zero-based offsets.\nselection.setOffsets(45, 55);\n\n// Hide the selection\nselection.hide();\n\n// Show the selection\nselection.show();\n\n// Remove the selection.\nselection.dispose();\n```\n\n### EditorContentManager \nThe EditorContentManager simplifies dealing with local and remote changes\nto the editor.\n\n```JavaScript\nconst editor = monaco.editor.create(document.getElementById(\"editor\"), {\n  value: \"function helloWorld = () =\u003e { console.log('hello world!')\",\n  theme: \"vs-dark'\",\n  language: 'javascript'\n});\n\nconst contentManager = new MonacoCollabExt.EditorContentManager({\n  editor: editor,\n  onInsert(index, text) {\n    console.log(\"Insert\", index, text);\n  },\n  onReplace(index, length, text) {\n    console.log(\"Replace\", index, length, text);\n  },\n  onDelete(index, length) {\n    console.log(\"Delete\", index, length);\n  }\n});\n\n// Insert text into the editor at offset 5.\ncontentManager.insert(5, \"some text\");\n\n// Replace the text in the editor at range 5 - 10.\ncontentManager.replace(5, 10, \"some text\");\n\n// Delete the text in the editor at range 5 - 10.\ncontentManager.delete(5, 10);\n\n// Release resources when done\ncontentManager.dispose();\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fconvergencelabs%2Fmonaco-collab-ext","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fconvergencelabs%2Fmonaco-collab-ext","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fconvergencelabs%2Fmonaco-collab-ext/lists"}
