Not really. I’m planning to work on this in my free time whenever I feel like it. In broad strokes, the first goal is to make sure that the simple code examples work on modern GHC versions (9.6+). Some later chapters dive into some specific libraries like gtk2hs which may take more time to fix. The story also needs to be adapted in some places, for example it explains head and tail on lists very early on which nowadays are considered to be less idiomatic.
If you have specific suggestions for what to focus on, I’d love to hear it.
Earlier this year I discovered that the online version of that book book.realworldhaskell.org/ just straight up vanished. I learned a lot from the sheer amount of useful comments in there. It would be a nice plus if we can also revive the comments.
Thanks for pointing that out and linking to the Wayback Machine! Integrating those old comments will be a challenge because we’d have to somehow scrape them all, check if they haven’t aged badly, link them to the current document, and properly integrate them into the markdown in an unobtrusive way (probably some for of details block, but that can still be a bit obtrusive if it is after every paragraph).
In short, I agree it would be a nice plus but it is not a priority in the short term.
I agree it’s not easy to integrate them, but I also found them very useful from time to time. I think someone writing such a book sometimes cannot get into the headspace of someone hearing about these concepts for the first time, so they can’t always anticipate the questions that will occur - but the other readers who were struggling along would ask those kinds of questions.
