This is a Visual Studio Code extension that helps users process code and Markdown files in a selected folder by converting them into a printable format. The extension:
Converts code files to Markdown: Any supported code file (See Supported Languages) in the selected folder is converted to a Markdown file with syntax highlighting and line numbers.
Converts Markdown files to HTML: Markdown files are then converted to HTML, combining them into one file.
Prepares a Printable HTML: It generates an HTML file that can be printed directly, with styled code blocks, line numbers, and integrated with the Katex library for rendering LaTeX.
Features
Supports multiple programming languages: See Supported Languages for more information
Line Numbers in Code: Code blocks are automatically numbered for better readability when printed.

Select Folder: You'll be prompted to select a folder containing code and Markdown files. The extension will process all code and Markdown files in the folder, including sub directories.
Markdown Conversion: The extension will convert code files to Markdown and place them in a new folder named print inside the selected folder.
Generate HTML: After converting the files to Markdown, the extension combines them into a single HTML file, which is saved in the same print folder.
