Cherrytree is a structured note taking application with support for rich text formatting and syntax highlighting for a number of common programming languages. Its files contain a related set of hierarchically arranged sub-documents, which Cherrytree calls nodes, that are organized in an outline structure. In addition to formatted text, nodes may also contain tables, images, embedded files, and code blocks. For many scripting languages, users may right click a code block to execute the code that it contains. Cherrytree files are exportable as PDFs, HTML websites, or folders of plain text files. The application website features a manual generated from a single Cherrytree file and the Downloads section of the site contains a Windows installer and .deb and .rpm package files for common Linux distributions. Section 3.4 of the Cherrytree manual outlines how technically inclined macOS users may install Cherrytree via Homebrew. Cherrytree is free software, distributed under the GNU General Public License, with source code available on GitHub.
