The Code Preview plugin for Obsidian allows users to preview code directly from within their notes. By specifying a file path, users can display portions of the code, highlighting specific lines or sections based on configurable parameters. The plugin supports a variety of features such as line range selection, regular expression matching, and text-based search for highlighting code. It also includes options for customizing the appearance, such as line numbers and background color for highlights. Ideal for developers and anyone working with code in Obsidian, the plugin offers an easy way to visualize and navigate through code files without leaving the note-taking environment.

The Interactive Code Blocks plugin enables users to create and preview interactive code blocks directly within Obsidian. Designed primarily for drafting and testing these blocks, the plugin offers a simplified preview experience for code snippets written in Markdown. Users can visualize code marked as 'runnable' or 'editable' with various options such as runner and sandbox modes. However, the plugin is limited to basic functionality and does not replicate the full capabilities of production plugins like the Quartz plugin used at Windesheim for displaying interactive blocks. This makes it an effective tool for drafting and refining code during the writing process.

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.
