Update to my (unofficial) #LuaLaTeX package "minos".

The most noteworthy change is that the "garamond" font profile now uses both Garamontio and GaramontioSans (both beautiful fonts are by @mc_wiki); it previously used the older Ysabeau (of which GaramontioSans is an improved fork) for sans-serif.

Also: further adjustments to Minion 3 kerning; some documentation fixes.

is there a way to configure #lualatex to abort on non-existent input file (instead of dumping me in this annoying shell that is annoying to leave?)

#TeXLaTeX #typography #Cheatsheet

My former student lent me their printed and bound copy of ‘Nine Chapters on the Semigroup Art’, my lecture notes for a tour through semigroup theory, in which they had marked various typos and minor errors, and points where they thought more explanation was required, so that I could make some improvements.

This was actually the first time I had ever seen it printed in full (photos attached). I had only printed individual chapters while working on it.

I think it looks pretty good, although I have improved the typography in the years since this copy was printed. In particular, I tightened the letter spacing used for theorem headers.

I released the #LuaLaTeX style "minos" I first developed for these notes (much revised and extended since) a few weeks ago: https://codeberg.org/ajcain/minos (Git repository) https://codeberg.org/ajcain/minos/releases (Documentation and source .zip/.tar.gz)

‘Nine Chapters’ itself is (and has always been) #OpenAccess: https://archive.org/details/cain_semigroups_a4_screen

I figured out how to make these previews work. The problem did turn out to be that lualatex doesn't produce .dvi files. The aptly named dvilualatex binary needs to be used for this. The solution was to set the latex-compiler property of the org-preview-latex-process-alist members accordingly:

"dvilualatex -interaction nonstopmode -output-directory %o %f"

To quote the Emacs enthusiast interview, you can probably do this in a smarter way (and I'm all ears/eyes for suggestions).

For now, though, it works! As with most problems, this one just needed a fresh set of eyes and putting the right words in the search engine.

Had I printed the #sydbox manual pages as a #pdf and sell it on a print-on-demand service, would you buy it to contribute to the project? It's pretty basic at the moment but looks roughly reasonable. Pipeline is #scdoc -> #man -> #pandoc -> #markdown -> #pandoc -> #latex -> #lualatex -> #pdf. I regenerate it every release, it's about 300 pages: https://gitlab.exherbo.org/sydbox/sydbox/-/blob/main/doc/manual/syd-manual.pdf #exherbo #linux #security

These are the new features the LaTeX #multilingual support (with #babel) has brought us this 2025. Remember that, unlike some AI chats mistakenly claim, babel provides comprehensive support for #LuaLaTeX and #XeLaTeX, as well as for #Unicode and #OpenType (with fontspec).

Small update to my (unofficial) #LuaLaTeX package "minos". Mostly small changes for consistency, with one substantial fix to typesetting the table of contents (The problem only arose when neither hyperref nor tagging-compatible code were being used.)

I have been perusing some beautifully typeset notes for three lectures on logic that @consequently shared recently: https://consequently.org/handouts/whl-l.pdf (sample pages attached)

The document has a very elegant combination of fonts (all freely available under the Open Font Licence):

• Alegraya ht for the body text [https://huertatipografica.com/en/fonts/alegreya-ht-pro];

• Alegraya Sans ht for the sidenotes and headings [https://huertatipografica.com/en/fonts/alegreya-sans-ht];

• AMS Euler for mathematics [exists in various versions, e.g. https://ctan.org/pkg/euler-math].

The layout is compact without being overly dense and the sidenotes are cleanly separated from the main text by colour and font.

I *think* the "ebproof" package [https://ctan.org/pkg/ebproof] was used for the proof trees. (Please correct me if I am wrong, @consequently)

I understand that my own package "marginalia" [https://ctan.org/pkg/marginalia] was used to create the sidenotes — and seeing it contribute in a small way to beautiful results like this is part of what makes package creation worthwhile. :-)

A few days ago I released publicly the #LuaLaTeX style "minos", which I developed and used for my books, including ‘Form & Number: A History of Mathematical Beauty’ [https://archive.org/details/cain_formandnumber_ebook_large] and ‘An Annotated Mathematician's Apology’ [https://archive.org/details/hardy_annotated].

As a result of various emails from some of the people who originally asked me to make it available, I have made some improvements to the code and documentation. (I still doubt it will ever be improved enough for me to submit it to CTAN as an ‘official’ package, although it is possible that I might separate parts of it into packages for CTAN.)

Some of the typographical techniques are discussed in an #OpenAccess article in TUGboat: https://tug.org/TUGboat/tb46-1/tb142cain-setting-form.html

#TeXLaTeX #typography

I have made available the #LuaLaTeX style used in my books, including ‘Form & Number: A History of Mathematical Beauty’ [https://archive.org/details/cain_formandnumber_ebook_large], after several people emailed me to express an interest. The style (called "minos") is available here: https://codeberg.org/ajcain/minos

The style was written for my own use, and so the documentation is basic and the functionality follows precisely my own needs. I am not going to submit it to CTAN. It is probably more useful as a source of ideas and experimentation than as a style for anyone else.

#TeXLaTeX #typography

A new version of my #LuaLaTeX package ‘marginalia’ is now available on CTAN. [https://ctan.org/pkg/marginalia]

A new feature allows adding an arrow or other symbol next to the line relevant to the marginal note. (Example attached.) Even if the position of the marginal note is automatically adjusted (to avoid overlaps etc.), the arrow remains in place.

New vertical alignment options are available: centrally positioned (probably better for placing pictures in the margin) or midway between top/bottom lines (probably better for text-only margin notes).

The documentation has been improved with more explanation and examples.

General info: ‘marginalia’ allows the placement of marginal notes (or other marginal content) anywhere, without \marginpar’s limits, and automatically adjusts positions to prevent either overlaps or content being pushed off the page, and uses key–value settings that allow fine-grained customization.

There is an #OpenAccess introduction to ‘marginalia’ in ‘TUGboat: Communications of the TeX Users Group’: https://www.tug.org/TUGboat/tb46-1/tb142cain-marginalia.pdf

Neil Soiffer und David Carlisle haben eine neue Website zum Testen von #OpenTypeMath-Schriftarten erstellt.

Sie ist hauptsächlich auf die #MathML Darstellung ausgerichtet, enthält aber auch Tests, die PDF-Dateien (auf texlive.net) generieren, die die #LuaLaTeX Darstellung der bereitgestellten Ausdrücke mit allen Schriftarten zeigen.

Hier stehen etwa 30 Schriftarten zur Verfügung, was wohl nahezu allen frei verfügbaren #OpenType #Mathematik #Schriftarten entspricht.

Add tagging to ‘Form & Number’ may take some time: I might have to implement a temporary replacement for the inline lists from the "enumitem" package (which I believe are not yet implemented for the new interfaces created by the tagging project), and I may have to refactor various pieces of dark magic in the ‘F&N’ #LuaLaTeX code.

‘Bertrand Russell & Trinity: A college controversy of the last war’ is a pamphlet written by G.H. Hardy in 1942, giving an account of the dismissal of Russell from his Trinity College lectureship in 1916 following his criminal conviction for anti-war political activity. (Hardy was at the time a fellow of Trinity and opposed Russell's ouster.)

I have uploaded a re-typeset version of Hardy's pamphlet to the Internet Archive [https://archive.org/details/hardy_russellandtrinity].

Creating this version was an exercise for me to learn how to (start to) adapt my LaTeX styles to the new interfaces created by the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/]. (A #TaggedPDF contains supplementary information to assist screen reading software, data extraction, etc.)

Also, Hardy's work is in the public domain; there seemed to be no downloadable ebook version of this pamphlet; and I thought that it would be a useful companion to the ‘Annotated Mathematician's Apology’ [https://archive.org/details/hardy_annotated].

I have made available the #LuaLaTeX source code on #Codeberg, in case anyone is interested in how the style was created: https://codeberg.org/ajcain/hardy_russellandtrinity

My #OpenAccess book ‘Form & Number: A History of Mathematical Beauty’ has been updated: https://archive.org/details/cain_formandnumber_ebook_large

Karl Berry, the treasurer of the TeX Users Group and one of the editors of its journal ‘TUGboat’, and Frank Plastria, Professor Emeritus at Vrije Universiteit Brussel, have (very kindly!) been reading and commenting on the text. Karl also ran his suite of automated tests on the #LuaLaTeX source files.

As a result, the new version incorporates many corrected typos and small improvements.

Thank you, Frank and Karl!

(The new PDF is available for download immediately; archive.org will re-generate images for the in-browser reader during the next few hours.)
