TikZJax is a JavaScript library that renders LaTeX-generated TikZ graphics directly within web pages. It eliminates the need for pre-rendering images and allows for dynamic, interactive diagrams. By leveraging the power of a browser's JavaScript engine and a server-side LaTeX compiler, TikZJax processes TikZ code on demand, offering flexibility and avoiding the limitations of static images. This enables features like responsive scaling, tooltips, and hyperlinks within the graphics, making it ideal for incorporating complex, mathematical, and scientific visualizations directly into HTML content.
This blog post explores using eqn, a pre-troff equation formatter, to generate MathML for static websites. The author details their process of converting eqn syntax to MathML using geqn and groff, emphasizing its simplicity and suitability for static site generation. They highlight eqn's ease of use compared to LaTeX and demonstrate the process with a practical example, showcasing the conversion steps and the resulting rendered MathML embedded in HTML. This approach allows for maintainable, human-readable equation source files while leveraging standard tools to produce accessible and widely compatible mathematical expressions on the web.
HN users largely praised the simplicity and elegance of using eqn for math rendering, particularly in contrast to MathJax or LaTeX. Several appreciated the author's demonstration of a straightforward, lightweight approach for static sites, avoiding JavaScript dependencies. Some discussed the limitations of eqn, such as lack of support for more complex equations and symbols, while others offered alternative tools like KaTeX and MathML. One user pointed out potential accessibility issues and suggested investigating MathML for better screen reader compatibility. The overall sentiment favored eqn for its ease of use in simple scenarios, but acknowledged the need for more robust solutions for complex mathematical content.

The Hacker News post about TikZJax, a tool for embedding LaTeX drawings in HTML, has generated a moderate discussion with several insightful comments. Many commenters express appreciation for the project, finding it useful and well-executed.
One commenter points out the advantage of TikZJax rendering on the client-side, eliminating the need for server-side generation of images. They highlight the benefit of dynamic updates and the potential for interactive diagrams. This aligns with the project's goal of providing a seamless way to include LaTeX drawings directly within web pages.
Another commenter questions the performance implications of client-side rendering, particularly for complex diagrams. They express concern about the computational overhead and potential slowdowns for users. This raises a valid point about the trade-off between dynamic rendering and performance, especially on less powerful devices.
The discussion also touches upon the broader topic of math rendering on the web, with MathJax mentioned as a related project. Commenters compare and contrast the two tools, acknowledging the advantages and disadvantages of each. This context helps situate TikZJax within the existing landscape of web-based mathematical and scientific communication tools.
A few comments delve into technical details, discussing the use of WebAssembly and JavaScript for rendering. This sheds light on the underlying technology powering TikZJax and provides insight into its implementation.
While some commenters express excitement about the possibilities offered by TikZJax, others suggest alternative approaches, such as pre-rendering diagrams to SVG format. This highlights different preferences and priorities within the community, with some valuing dynamic updates while others prefer static, pre-rendered content for performance reasons.
Overall, the comments on the Hacker News post reflect a generally positive reception to TikZJax, with commenters acknowledging its potential and utility. However, concerns about performance and comparisons to other tools provide a balanced perspective on the project's strengths and limitations. The discussion contributes to a better understanding of the challenges and opportunities related to embedding LaTeX drawings in web pages.
