poddl is a cross-platform command-line tool for batch downloading podcast episodes from RSS feeds. It fetches the RSS XML via libcurl, parses it using regex to extract episode titles, URLs, and publication dates, then downloads media files to a specified output directory. The tool supports a variety of options including downloading individual episodes, ranges, newest-first ordering, filename formatting with episode numbers and dates, whitespace handling, and early termination on existing files. The codebase is a monolithic C++11 application split into several classes: Client (HTTP), Parser (RSS parsing), Helper (utilities), FileSystem (cross-platform file operations), and a standalone HtmlCoder for decoding HTML entities. The architecture is clean and modular, with clear separation of concerns, though the use of regex for XML parsing is a known fragility. The repository includes precompiled binaries for Windows and Linux, and the build requires only g++ and libcurl. It is a straightforward, well-structured utility with no external runtime dependencies beyond libcurl.
