epub3-samples VS scroll

With MathML epubs can look decent. For example take a look at the sample MathML epub "A First Course In Linear Algebra" [0] (in a reader that supports MathML of course). It looks pretty good. The problem is Amazon STILL doesn't support MathML, so publishers just churn out a gross version where all the equations are images and so then it doesn't scale properly with the text and the book becomes 300+ MB because of it. And they can't be bothered to make two versions for readers like Kobo that do support MathML.

For example, if you want to open epub files like https://github.com/IDPF/epub3-samples/releases/download/20170606/accessible_epub_3.epub inside Brave, you will have to install an epub reader extension then instead of downloading it will open inside Brave, if you want to change that behavior you have to disable the extension or limit the extension's domain list, or you right click and "save link as file", but unless the extension has the settings, there is no way to tell Brave to use extension or download manager depending on extensions, unless the extension gets disabled. And if you have an external epub reader, well, you can automatically open the extension when you tell Brave to do it as well.

I've worked on a ePub parse and renderer and the issues you're describing sound pretty familiar.

The three main components of the ePub (aside from the actual pages) are the TOC, the spine and the manifest. The manifest basically tells you where everything is, the TOC is the table of contents which can link to various pages and the spine gives you the traversal order.

Some mistakes I've seen are using the TOC to traverse the book. Using the spine to traverse the book but not handling hidden pages properly. Not handling two page spread properly.

So yeah the spec is nuanced and it would be easy to make a reader that worked with a lot of books but then had weird issues on another set of books that aren't particularly different.

I recall using this repo (https://github.com/IDPF/epub3-samples) to test specific functionality to make sure it was in line with the spec.

It took me many years to get Scroll (https://scroll.pub/) to the point where I love it and am confident it will be the dominant language for writing going forward (replacing markdown).

I first had to invent Tree Notation (2017), which I got wrong on my first two tries (2012's Note and 2013's Space). Then I needed to invent Grammar (2017), and then I made the predecessor to Scroll called Dumbdown (2019). 2 years after that I shipped the first version of Scroll (2021).

Now we are on Scroll version 58 and it's blazing fast, very simple, extremely extendible, and scales very well.

It was 90% me for a while, but recently been very much a team effort.

It took a while to get right because it's a whole new kind of language, so there were a lot of mistakes that I made and had to undo, and it took a while to figure out exactly what was special about it and how to double down on that.

I recently started 2 new newspapers: https://longbeach.pub/ and http://hawaii.pub/. Very different from traditional newspapers in that they are: public domain, open source (view source on every page), and built using a new language (https://scroll.pub/).

Another cool site I found recently (via the replit guy) is https://www.rootclaim.com/

Very cool way to present arguments.

I'm thinking of taking that, as well as argdown, and building some easy to use keywords in scroll https://scroll.pub/

> Context-free grammars, and their associated parsing techniques, don't align well with real-world compilers, and thus we should deemphasise CFGs (Context-Free Grammars) and their associated parsing algorithms.

I think CFG are highly overrated. Top down recursive descent parsers are simple and allow you to craft more human languages. I think building top down parsers is something every dev should do. It's a simple technique with tremendous power.

I think the source code for Scroll (https://github.com/breck7/scroll/tree/main/grammar) demonstrates how liberating moving away from CFGs can be. Easy to extend, compose, build new backends, debug, et cetera. Parser, compiler, and interpreter for each node all in one place. Swap nodes around between languages. Great evolutionary characteristics.

I'll stop there (realizing I need to improve the docs and write a blog post).

- Uses a new language called Scroll: https://scroll.pub/

Also, put down Markdown and give our Scroll a try: https://scroll.pub

It now powers sites like my own blog (https://breckyunits.com/), knowledge bases like PLDB.com, and our first new public domain daily newspaper called the Long Beach Pub (https://longbeach.pub/1-3-2023.html).

> Java, Go, Javascript, Rust, etc are all regularly written with whitespace, and have tools to enforce such formatting, but they don't derive information from it.

Ah you reminded me. A curious phenomenon I've observed with Prettier in JS and fmt in Go is languages are moving to standardized whitespace, but as you said, not yet deriving information from it. I don't know enough about Java or Rust but I suspect they probably both have adopted a Prettier/fmt like convention where all code is formatted on save. So it seems like we are moving to a world where it will be a simple flip of a switch to then start having popular languages extract meaning from the whitespace.

> Also, Python has existed for decades and still there is little further adoption of indentation-sensitivity. It doesn't seem like a wave of indentation-sensitive languages will be coming any time soon.

I think it's coming big time this year. I think our Scroll (https://scroll.pub/) will catch fire and be the go to language instead of Markdown by the end of the year. Then with the increasing success of TreeBase (powering PLDB and others) we will start to see JSON fall for config formats and document storage databases. A lot more will happen to, data vis will be a big one, but those 2 I'm reasonably certain of happening in 2023.

GoAccess: https://goaccess.io/. I don't miss Google Analytics at all.

Loom. It's not open source I don't think but I'm digging it and excited when a public domain competitor comes out.

Our https://scroll.pub/. It's far beyond markdown at this point. I am able to not only write better but also maintain thousands of pages of content by hand (well, most of the credit for that belongs to Apple M1s, Sublime Text, git, MacOS, and Github). The stuff we are doing with it now would just not be possible with anything else, and what we're coming out with next year is super exciting. It's all public domain.
