New blog!

Following on from the post about converting plain text source to EPUB-ready xhtml...

This new post introduces the plain text music notation format called 'abc', and describes how the SEED.html app can be set up to convert abc code block within markdown content to inline SVG images for responsive digital sheet music.

New blog!

I wrote about the various plain text formats I’ve tried as source content for EPUB books in the SEED.html app.

Maybe you know some of them: markdown, textile, org-mode, asciidoc, LaTeX and fountain

Have you heard of Invisible XML?

With it you create a grammar that describes the structure of a plain text document so it can be handled with XML tools. Very apropos.

Turns out there's a javascript implementation of the parser (Grammix), which runs in a browser. Very exciting!

The blog post shows an EPUB created with markdown and textile grammars and a single ixml parser.

A podcast inspired me to learn what a language shift is in EPUB and whip something up in the SEED.html app

I read a slide deck from 2012 about scripted EPUB in the iBooks app. Here’s what I thought of it in relation to the SEED.html app in 2025.

I blogged!

This post describes an EPUB 3 file that presents audio clips and flashcard-style toggling of individual Georgian phrases.

The material is derived from a book called Beginner's Georgian by Dodona Kiziria published by Hippocrene.

I'm well out of my lane now, making language education resources. But this is the exact presentation of text/audio that I wanted when I started learning Georgian from this book.

This week I have mostly been open sourcing the SEED.html project.

It’s now on GitHub with an MIT license.

Here's a slightly technical blog post about what goes into a SEED.html EPUB file that makes it different to regular EPUB 3.

New blog post includes embedded EPUB with playable Georgian folk song practice materials by ensemble Adilei.

And tasteful animated svg playback indicator.

The post uses epub.js and loads an unzipped epub package from cloudflare instead of the .epub directly.

I created an EPUB specifically for the blog.

It includes a code listing for the reading system script that I use for responsive EPUB layouts.

You can read the EPUB in the blog post, download it for your own device, or edit it directly in the SEED.html app.
