<div dir="ltr"><div class="gmail_quote"><div class="gmail_attr">Hi</div><div class="gmail_attr"><br></div><div class="gmail_attr">First a word about this year's TeX Conference (online 22-24 July, and free). There's renewed interest in the TeX/LaTeX community in accessibility, with 6 important talks on it last year (including my own). This year I'll be talking about "Access and Accessibility". It's based on a comment by Jonathan Godfrey (a blind lecturer in statistics), that sighted people not having easy access to tools that generate accessible content is a major obstacle.</div><div class="gmail_attr"><br></div><div class="gmail_attr">Today's TeX Hour is about Access to TeX and related tools. In particular, it's about allowing a working environment on one machine to be accurately (even exactly) reproduced on another machine. The focus tomorrow is on fonts and TeX macros, but the methods apply much more widely.</div><div class="gmail_attr"><br></div><div class="gmail_attr"><div class="gmail_quote">Here's the link for tomorrow's TeX Hour: Thursday 12 April, 6:30 to 7:30pm UK time.<br>Zoom URL: <a href="https://us02web.zoom.us/j/78551255396?pwd=cHdJN0pTTXRlRCtSd1lCTHpuWmNIUT09" rel="noreferrer" target="_blank">https://us02web.zoom.us/j/78551255396?pwd=cHdJN0pTTXRlRCtSd1lCTHpuWmNIUT09</a><br>Note: Both the UK and USA are on Summer Time. UK Time Now: <a href="https://time.is/UK" rel="noreferrer" target="_blank">https://time.is/UK</a>.</div><br class="gmail-Apple-interchange-newline"></div><div class="gmail_attr">Back to tools for accurately reproducing an environment. I hope in time these methods will help visually impaired users share their software situation and configuration with others. In particular, an easy method of creating a truly reproducible problem, fault and bug reports. And reproducible solutions.</div><div class="gmail_attr"><br></div><div class="gmail_attr">If you're interested in this, or would like to contribute to the TeX Conference please do get in touch. By the way, one of the keynote speakers is an expert in <a href="https://en.wikipedia.org/wiki/Darwin_Information_Typing_Architecture">https://en.wikipedia.org/wiki/Darwin_Information_Typing_Architecture</a>, which is widely used for technical documention.</div><div class="gmail_attr"><a href="https://www.routledge.com/Creating-Intelligent-Content-with-Lightweight-DITA/Evia/p/book/9780815393825">https://www.routledge.com/Creating-Intelligent-Content-with-Lightweight-DITA/Evia/p/book/9780815393825</a><br></div><div class="gmail_attr"><a href="https://tug.org/tug2022/">https://tug.org/tug2022/</a><br></div><div class="gmail_attr"><br></div><div class="gmail_attr">Now for the technical stuff about tomorrow's TeX Hour. After a long battle between my stubborness and my stupidity, I've made a sideways move that greatly takes me forward. Briefly, I've created a folder /git-alt-obj/texlive on my PC that contains all the non-binary files in the TeX Live installations from 2010 to 2022. At present it occupies 33G, but once duplicates are removed I expect it will be less than 8G.</div><div class="gmail_attr"><br></div><div class="gmail_attr">Because it uses git pack files subsets and minor variations in the content will be inexpensive. In git, branches are cheap, because only the differences are recorded. Proceeding in this way for TeX/LaTeX, Python, Pandoc and other tools it will I hope be rather easier to create and share software environments for creating accessible documents, and to report and reproduce problems when they arise.</div><div class="gmail_attr"><br></div><div class="gmail_attr">Here's the tool I wrote and used to turn a folder into a git pack file <a href="https://github.com/jfine2358/scratch/blob/y2022p008/pack_dir.sh">https://github.com/jfine2358/scratch/blob/y2022p008/pack_dir.sh</a></div><div class="gmail_attr"><br></div><div class="gmail_attr">And here's a description of how I use it's output. I'll talk about that, and how to remove duplicates and how to subset and distribute the nearly approximately 1,850,000 files in /git-alt-obj/texlive/pack.</div><div class="gmail_attr"><br></div><div class="gmail_attr">wishing you happy, safe and reproducible TeXing</div><div class="gmail_attr"><br></div><div class="gmail_attr">Jonathan</div><div class="gmail_attr"><br></div><div class="gmail_attr">PS. Do get in touch with me if you're interested in this year's TeX conference, as participant or even as a contributor. Perhaps we could have an accessibility panel. I'd like that.</div>
