In plain English

BlackGooDay is a proof-of-concept tool that converts Markdown-formatted text into Microsoft Word (.docx) documents. In simple terms, you give it text written in Markdown, the lightweight formatting language popular with developers and bloggers, and it spits out a Word file you can open in Microsoft Office or Google Docs. The project stitches together two existing Go libraries to get the job done. The first, Blackfriday, reads and interprets the Markdown formatting (things like headers, bold text, and lists). The second, gooxml, handles the creation of the actual .docx file using the Office Open XML format that Word documents are built on. The author describes the implementation as "hacky," which is a fair warning that this is experimental code rather than a polished product. This tool would appeal to someone who writes in Markdown but needs to hand off a Word document to a colleague, client, or stakeholder who expects a traditional file. For example, a developer who keeps notes in Markdown might want to generate a .docx status report for a project manager, or a technical writer might draft content in Markdown and convert it for review by non-technical teammates. It is worth noting that this is explicitly a proof of concept born from a casual tweet, not a production-ready tool. The README is sparse, just a single command to run it and a few links to related projects. There is no installation guide, no list of supported Markdown features, and no documentation about formatting options or limitations. Anyone considering using it should expect to dig into the source code to understand what it can and cannot do.

Copy-paste prompts

Prompt 1
Write a Go program that takes a Markdown string, parses it with Blackfriday, and converts the output to a .docx file using gooxml, following the approach in the BlackGooDay project.
Prompt 2
Read the BlackGooDay source code and list which Markdown elements (headers, bold, lists, links, etc.) are supported and which are missing or broken.
Prompt 3
Create a simple command-line tool in Go that accepts a Markdown file path as input and writes a .docx file, inspired by the BlackGooDay proof-of-concept.
Prompt 4
Compare the Blackfriday and gooxml libraries used in BlackGooDay and explain how they work together to turn Markdown into a Word document.
