For the katex folder path, as I remember it was difficult to refer to external files in Scribble. If you manage to find a way to load a dummy.js script the way you want to, I can try to integrate your technique into scribble-math. However as things stand now, I have no idea about how to do that path customization :disappointed:.

Thanks again for all your support @suzanne.soy. Now the \tag function is working properly, as well as the \boxed function, in the HTML rendering. For the following code: #lang scribble/manual @require[scribble-math] @$${\tag{1} \boxed{\mathsf{e}^{i\pi}+1=0}} We have as a result the attached image.

This is great. Btw I’m giving a very small workshop for some of my students with the name “Mathematical Exposition with Scribble” (in spanish), and scribble-math is the main tool for mathematical expressions and formulae, as well as drawings. And now it’s even better. I really appreciate all your help.

Concerning the katex folder. I apologize because I don’t know js. But If I knew exactly where is the code that creates the katex folder, then I can do some experiments with it.

Note: in a next message I expect to share with you (in a racket like syntax,) the main idea about a common katex folder.

Thanks again for your support for this very nice and useful package. Best regards.

With respect to the katex common folder. The idea to have only one location in a common set of scribble documents, is the following (in a racket like syntax). (if common-katex-folder? (begin (create-katex-folder-holder (string-append "..\" common-katex-folder-holder-name)) (create-and-fill-katex-folder-at (string-append "..\" common-katex-folder-holder-name "\katex"))) (create-and-fill-katex-folder-at "\katex")) Where, for the current implementation the identifier common-katex-folder? is false. The following diagram may be can express better the idea: Thank you very much for observations and comments. Best Regards.
