Snippet Collection

Organization

massCode allows you to organize snippets using multi-level folders as well as tags. Each snippet has fragments - tabs, which gives even greater level of organization.

Editor

massCode uses Codemirror as the basis for the editor and .tmLanguage as the grammar for syntax highlighting. This tandem opens the door to over 600 existing grammars. The application currently supports more than 160 grammars. In addition to .tmLanguage, the application supports .tmTheme for themes. There is also support for Prettier for code formatting.

Markdown

massCode allows you to write in Markdown and provide support to syntax highlighting, tables, list and other formatting. Also massCode supports Mermaid - diagramming and charting tool that renders Markdown-inspired text definitions to create and modify diagrams dynamically.

Presentation Mode

massCode allows you to make a presentation out of a sequence of snippets. It's great for classroom use, team meetings, conferences or simply reviewing notes on your own.

Real-time Render for HTML & CSS

You can not only collect snippets, but also see the rendering result for HTML and CSS in real time. Test the idea or just view the result.
