Manual translation is not only slow, but it often breaks Markdown formatting, specifically code blocks, image paths, and internal links. I built this lightweight Python tool to automate the process while ensuring the structural integrity of my documentation remains intact.</p> <p>Key Features<br> Markdown-Aware: Designed to preserve complex formatting, ensuring that code blocks and tables stay functional after translation.</p> <p>AI-Powered: Utilizes LLM APIs to provide context-aware, high-quality translations that sound natural.</p> <p>Lightweight: The entire core logic runs in under 50 lines of Python code, making it easy to integrate into your workflow.</p> <p>How It Works<br> The script iterates through your Markdown files and sends the content to the AI API, while keeping the Markdown syntax markers preserved.<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight python"><code><span class="kn">import</span> <span class="n">os</span> <span class="kn">import</span> <span class="n">openai</span> <span class="k">def</span> <span class="nf">translate_markdown</span><span class="p">(</span><span class="n">file_path</span><span class="p">):</span> <span class="c1"># Your implementation details here </span> <span class="k">pass</span> </code></pre> </div> <p>Final Thoughts<br> This tool has significantly streamlined my documentation process. I hope it helps you stay focused on coding rather than formatting.</p> <p>Feel free to try it out and let me know your thoughts in the comments!
