The Code Link plugin allows you to link directly to code files and even specific symbols within those files, such as functions or classes, making it ideal for referencing code in your Obsidian notes. By embedding or previewing the contents of linked code, you can focus on the specific parts of a project that interest you. The plugin supports hover previews and embedded previews of code files. Additionally, tag search allows you to filter through code by symbols, making it easier to navigate complex codebases. With support for multiple languages and integration with TreeSitter, the plugin enhances code documentation and study in Obsidian.
