NodeJS approach to producing SVGs about jssm HOT 7 CLOSED

This is now implemented in jssm-viz and the cli is mostly done

The github action is also mostly done

from jssm.

the mechanism is dot_to_string in jssm-viz

you can see it in use in graph explorer in the svg button on the top edge of the editor window

i'm sorry it took me so long to notice these, @sunwukonga

from jssm.

i haven't actually tried this in node actually

svg_el would need a dom (which you could supplement with jsdom) but dot_to_string(dot( /*graph*/ )) shouldn't

i believe that should Just Work ™

I'll try to get a tutorial together on this this weekend (no promises)

from jssm.

hm

it looks like i actually took a stab at this a year ago

at the moment node's just up and dying when you load the bundle

that said the author expects this to work in node, and has examples. i'll see if i can figure out what the difference is

Okay.

It's not really ready for prime time, but, there is now a cli that can consume fsl and produce svg on disk.

It only produces them in the same location as the source right now (there's a bunch of command line options to change that but they're not honored yet)

It doesn't do any of the other image formats yet

But it does work

from jssm.

I just realized you want the SVG in your app, not as a CLI

That's also implemented in there

const svg_code = await fsl_to_svg_string(fsl_code);

I need to document this but I'm closing the issue because I believe it to be complete

If that's not correct, please re-open it and/or tag me

from jssm.

Actually, there's a live instance of jssm-viz bound to window on graph explorer, so you can just open a developer console and try it there

const viz = window.jssm_viz;
await viz.fsl_to_svg_string('this => is -> an ~> example;');

works in node too
