Massimiliano,
I have not read the book and cannot confidently make the assessment you describe. I do not know what the main author of TeXmacs has written in that book. I just outlined what is considered standard at university level. The book is about how to use a particular implementation of software. Became aware of TeXmacs around 2013 after a talk by François Poulain. Have reviewed TeXmacs a number of times since then - but I could not really recommend it. But do hope to change my mind about it, because I can see some benefits in using it if specific criticisms are tackled. The distribution of a book relates to its value for readers. An author must accept that a limited circulation book will not earn much money. Few authors do. Inflating its price as we have seen with Elsevier and others is a disease that requires eradication. Thusly I refuse to involve myself in peer-review.for the benefit of publishers who mistreat readers with vastly inflated prices, while at the same time campaigning for exclusive legal rights of exploitation to be granted to them by governments. Be reminded that my discussion with Joris (and which I am glad he responded directly) went far beyond the development contribution, elaborating on topics that are at director and institutional levels. And we have found much agreement and recognition of the challenges at hand. The challenge has no similarities to what has been seen recently in the software community (vis Richard Stallman, Eric Raymond, Linus Torvalds). Do not interpret it that way. Neither should I be associated with Open Source Projects, as it is something I don't agree with. As Directeur de Recherche, Joris is quite capable of responding forcefully at unjust criticism as befitting to his position. What I can do is encourage and inspire the world to change some attitudes, in ways that will make the institutions we work with, the best they can be. Together with others, we can work so that true human capabilities can find expression.

You can check here some metrics: https://www.openhub.net/p/texmacs TeXmacs has ~250.000 lines of C++ and ~200.000 lines of Scheme code. The great majority of this code has been written by Joris since 17 years: https://www.openhub.net/p/texmacs/contributors/summary I've joined the project in 2006 and I witnessed the constant work which Joris delivers in bugfixes, new substantial features, quality control over contributions by others, etc.. It is fair to say that a large community of users profits everyday from this work. As for documentation we have a 260 pages user manual, a 50 pages developer guide and a 150 pages manual for the scheme extensions. All free and available in the program. There is a forum and a blog https://texmacs.github.io/notes/docs/main.html with some tutorials. Joris himself created also few video tutorials (the only one available so far), available on youtube and on our own web site. So I find quite puzzling your critique, and frankly quite unjust. Maybe were you not aware of their existence? I feel that Joris has the right to write and distribute whatever he likes, especially given the fact that his contribution to the project is already substantial without the book. I personally bought several copies to give as gift to friends. I do not share the opinion of Alvaro that the book should be made free. The program is free software and everybody can write documentation, tutorials for it. Is not the obligation of Joris to do more than he already does and I'm quite fine with him publishing a great book for 50 euros, as I would be if he would publish a literary work with a standard publisher. You cannot compare a book with a small distribution like one on TeXmacs with a widespread book on Algebra used by many more students. As with other publications students can ask libraries to but the book, libraries which already have books on TeX and LaTeX which are similarly prices: Lamport's LaTeX book is $44 euros on amazon: https://www.amazon.com/LaTeX-Document-Preparation-System-2nd/dp/0201529831 But, as everybody using TeXmacs regularly knows, you do not have to have the book to use it. Many of us learned to use TeXmacs before and without Joris' book. You can go in the forum and ask information, you can read the sources and see how to do something, you can read the blog for specific tutorials written by other collaborators like Giovanni. TeXmacs is a great project I'm quite proud to contribute to. I never felt any problem with Joris' book. Open source projects needs support and love from users which understand and value the dedication and hard work needed to make them successful. Best regards, Massimiliano Gubinelli
