Pandoc Celebrates Twenty Years Since Its Initial Release

Two Decades of Pandoc

Pandoc, a universal document converter, is celebrating its twentieth anniversary. The first version was released on August 3, 2006, under the GPL license. Initially, it consisted of approximately 3000 lines of Haskell code and could convert between Markdown, reStructuredText, HTML, LaTeX, RTF, and S5 formats.

Growth and Integration

Over the past two decades, Pandoc has seen over two hundred releases and expanded its capabilities significantly. It now supports more than fifty document formats and includes features like automatic citation and bibliography generation. Pandoc has also been integrated into academic writing tools such as Quarto and Jupyter Notebook, and is installed on millions of computers globally.

Origins in Haskell

The creator, John MacFarlane, chose to write Pandoc in Haskell not because he initially set out to build a document converter, but because he wanted to learn Haskell. He was intrigued by the language after a friend's recommendation and decided to write a Markdown parser as a learning project, which eventually evolved into Pandoc. Haskell's suitability for parsers and its parser combinator library (parsec) influenced this decision.
