I discovered this book after I read Jean's wonderful Extending Lilypond webpage.
Glad that you liked it.
I tried to access the URL but it didn't work. I've only found the Github repository of the book but it is really difficult to read portions of it in this state. Sometimes even referenced links in the repository display 404s.
If you clone the repository, the Markdown input is pretty readable in plain text.
Is the website/project dead for good or it will be back eventually? I'm really looking to get more serious with Scheme and any resources I can find certainly help.
I want to mention here that not so long ago I also wrote a Scheme tutorial in French: https://tutoriel-scheme.readthedocs.io/fr/latest/index.html This was done on request from some participants of the French-speaking “Café Lily” held remotely, where I gave a presentation of Scheme. Compared to Urs' work, I would describe it as more straightforward or fast-paced (depending on your point of view), and less theoretical. It might also be more suited to people who have little background in programming in general (Urs walks through a lot of concepts in order; I don't dive into great details and try to lay out the information in an order that doesn't require look-ahead from the reader). Clearly, there is a gap to be filled in the domain of Scheme tutorials. Urs' is excellent (and inspired parts of mine). What I missed in it when using it to learn Scheme myself was a description of ways to write loops (like recursivity). I could translate mine into English (modulo finding the time since my contributor's stack is quite full at the moment). I'm not sure if this is the best way to go: do people here have experience or desires on how much a Scheme tutorial that would be or have been useful for them should be targeted at complete programming novices (as opposed to people who know other programming languages though possibly only imperative ones), and the extent to which it should go into the details and concepts? A last consideration is that LilyPond's documentation itself contains a Scheme tutorial: https://lilypond.org/doc/v2.22/Documentation/extending/scheme-in-lilypond In its current state, it's not really useful to learn Scheme (I say this from not so old experience). However, it could be a target for introducing a better resource that would be updated at the same time as the rest of the documentation when LilyPond moves forward. On the other hand, official LilyPond documentation isn't the place to put loads of information about the elements of Scheme dissected: there is no point in asking LilyPond contributors to track and update documentation that is not directly linked to LilyPond. Thoughts on this? Best regards, Jean
