This is a Visual Studio Code extension that helps users process code and Markdown files in a selected file or 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.
Supports multiple programming languages: See Supported Languages for more information
Line Numbers in Code: Code blocks are automatically numbered for better readability when printed.
LaTeX Support: Uses Katex to render LaTeX expressions in Markdown.
Print-Friendly HTML: Converts Markdown to HTML with an automatic print trigger, allowing users to print the document directly from their browser.
Ignore files that you don't want to print: (Ctrl+Shift+P) and type Preferences: Open User Settings. Search for prettyprintcode.ignore and add your patterns to ignore.
Custom header & footer templates: Adjust prettyprintcode.documentHeader / prettyprintcode.documentFooter to override the per-file header and footer. Placeholders such as {{displayPath}}, {{relativePath}}, {{fileName}}, and their raw variants are supported. Pair with prettyprintcode.headerFooterStyles to add bespoke CSS.
Activate the Extension: Right click on a file or folder in the explorer and choose Pretty Print. Alternatively: Open the Command Palette (Ctrl+Shift+P) and type Pretty Print. Choose the Pretty Print command to activate it. Select File or Folder: You'll be prompted to select what you want to print. The extension will process the selected file, or every code and Markdown file inside the chosen folder (including sub directories).
Markdown Conversion: The extension converts code files to Markdown and places the generated files in a print folder next to your selection. When a folder is chosen, that folder gets the print directory. When a single file is chosen, the print directory is created alongside that file.
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.
Open & Print: The HTML file will automatically open in your default web browser, where you can print the document.
