Pieter Belmans has just finished upgrading the Stacks project website to a new version where the mathematics is rendered on the tag lookup pages. It is totally amazing! I was originally skeptical that this could be done with the current state of technology. However, when Pieter showed me what it looks like on a test website I was immediately convinced. The rendering of the material (including formulas and commutative diagrams) makes reading the Stacks project material online very comfortable and much faster than before.
The new version is made possible by
- Pieter’s code that parses the Stacks project LaTeX,
- MathJax for rendering the math formulae, and
- XyJax to render commutative diagrams coded with xypic.
I believe this makes the Stacks project website the first public website to use XyJax to render commutative diagrams online. Woohoo!
Here are some things to be aware of when using the new version:
- there are some issues in Opera,
- not all TeX is parsed perfectly (for instance complex footnotes),
- if you encounter something that doesn’t work, please contact us. You can leave a bug report on here, or you can email the stacks project maintainer.
Hi Johan, this is great! I hope you’re letting google bots etc crawl the index so that the text is now google searchable.
Google has been indexing the Stacks project tag lookup pages since their inception (2012-05-04) and of course Google has been indexing the pdfs of chapters and the whole book from the start (2005).
It looks great! The only thing I notice in that example is that (for firefox 17.0 at least) the double-prime superscript is being rendered as a closing double quote mark.
