Aside: I hope these ideas will in time help developers put LaTeX accessibility tools into the hands of authors and support staff. Also, they may help authors transition to new add-tags LaTeX. And help with the reprocessing of legacy documents.


Tomorrow's TeX Hour is about understanding and refactoring TeX Live to make it more flexible and agile.  The TeX Hour is Thursday 27 May, 6:30 to 7:30pm UK time.

Last week Yihui Xie explained why and how he developed TinyTeX to support users of R-Markdown. This greatly reduces the barrier to entry to using TeX. TinyTeX is a 100MB subset of TeXLive. My first PC, bought in 1989 to run TeX, had a 40MB hard disk (and 2MB of memory and a 10Mhz CPU).

Don Knuth wrote TeX to be archival. To give identical results from identical inputs. My TeX source file is just one of many inputs. Recording and exactly reproducing the other inputs is vital, to fully benefit from the hard work of Don Knuth that made TeX archival.

One goal is to make it much easier to archive all the resources used when a document is typeset. And at a different time and place, and on a different machine, gather those resources to typeset the document again. Maybe via GitHub actions, as part of Continuous Integration.

Another goal is to make it much easier to package a subset of TeX just for a special purpose. Beginner? You want to make a math presentation? Download and install a Beamer app. A few minutes later, you're ready to start authoring.

Interested? Please email me, or come along to the TeX Hour. I welcome your experience and ideas. My starting point will be statistics from the last ten years of the TeX Live DVDs.
