writing VS queryjevko.js

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. ;)

The grammar of S-exps on the other hand, I won't quote here, but I assure you it's much more complicated. How much depends on your flavor (Jevko is also simpler in this regard: there is only one flavor, clearly specified).

There is no (intended) ambiguity around whitespace in Jevko: whitespace does not occur explicitly in the grammar. Whitespace characters are just characters. This is the defining feature of the syntax.

For this reason Jevko is more low-level: if you want to treat whitespace in some special way, you have to do that yourself. Although for most use-cases this is very similar and simple, e.g. https://news.ycombinator.com/item?id=33334314

But the point is that you can also leave it as-is, e.g.: https://github.com/jevko/queryjevko.js

or do something else -- it's up to your format.

Thank you. :)

I'd be honored!

A couple of ideas:

How about a simple configuration format? https://gist.github.com/djedr/681e0199859874b3324eaa84192c42... (I should make a library out of this)

Or you can put it in your query strings to make them more humane: https://github.com/jevko/queryjevko.js

Or make up a markup DSL: https://github.com/jevko/markup-experiments#asttohtmltable

Or serialize game objects in your indie game. Or make it the interface of your experimental app. Or use it to shave off a few unnecessary characters off your data: https://jevko.github.io/compactness.html

No parser in your favorite language? A basic one should be only a couple dozen lines!
