jevkalk VS writing

[1] Here's one of my tries: https://github.com/jevko/jevkalk

Here is a toy language that uses Jevko as syntax that I've been hacking on a bit recently: https://github.com/jevko/jevkalk

> is doing? It sure looks to me like it's asking whether a symbol (i.e. indivisible atom) ends with an equal sign, which is semantic gibberish.

There are no symbols or indivisible atoms here.

What's happening here is parsing. `jevkoToHtml` is a kind of parser-transpiler which operates on a syntax tree, rather than a sequence of characters or tokens.

The syntax tree is the output of an earlier stage of parsing, done by the Jevko parser.

So you can think of this as multi-pass parsing, by analogy with multi-pass compilation.

At the same time as this second pass of parsing is happening, translation to HTML is happening as well.

Hope this clarifies things!

I had the same idea. Simple enough, but still. Brackets are simpler to formalize and implement and not harder to explain.

> They also put some thought into designing a query language for their rose-tree-like data model, which might be adaptable to Jevko — though they label only nodes, and Jevko labels both nodes (with suffixes) and arcs (with prefixes).

Yes, that might be interesting to look at, thanks for pointing it out. I have thought about this and came up with some ideas, but haven't decided on anything. I was thinking more along the lines of having the path DSL be simply implemented on top of Jevko, not as a completely separate grammar.

> Maybe that's the subtitle for Jevko? "A minimal Unicode syntax for ordered trees with labeled nodes and labeled arcs." If that's the intended semantics it would be pretty easy to whip up a diagram in Dot to illustrate it.

It's a nice description, but I think a little to detailed and technical to fit into a tagline. Maybe a little explanatory article with the diagram included. Would probably look something like this:

Although I'd gladly see your take on it. ;)
