What is CodeMirror?
CodeMirror is an open-source browser-based text editor intended for use in web applications. It provides functionality similar to text editors designed for coding, such as syntax highlighting, automatic indentation, search and replace, and bracket matching.
Some key features of CodeMirror include:
- Support for over 100 programming languages and markup languages including JavaScript, Python, XML, and HTML
- Theme support for customizable syntax highlighting colors and styles
- A large selection of addons and plugins for extra functionality like code folding, linting, autocompletion, and more
- Options for line numbers, scrollbars, read-only mode, and other editing features
- Multi-cursor and bi-directional text support
- API for programmatic control and integration into apps
- Small footprint and no dependencies, allowing easy implementation
CodeMirror can be used to add syntax highlighting to existing textareas or provide more advanced code editors. It is highly customizable both visually and functionally. Common uses include embedding CodeMirror as the code editor in web-based IDEs, providing an interface for demonstrating code examples, adding coding functionality to CMSs and other applications, and implementing code playgrounds.
