svg export from python

[jotech]

Is it possible to export the map made by escher directly from python?
I mean something like this:

b = escher.Builder (...)
b.export_svg (...)

It would be usefull to integrate escher in other web apps.

This isn't currently possible from Python or without a web browser in general. The Escher rendering all happens in the browser DOM, so the only way to run Escher from the command line would be to use 'headless' node.js, as described here. I haven't tried this, but we can put it on the development roadmap.

Alternatively, if the web app is running in a browser, you could generate an Escher map in a hidden div, and save the SVG file with a JavaScript function, like this:

var b = escher.Builder(map_data, null, embedded_css, { selection: d3.select('#my_hidden_div') };
b.map.save_svg();

This headless node.js sounds interesting!
I'm now using b.save_html() as a workaround.
The html file can be parsed and integrated well.

thank you @zakandrewking for your nice and usefull work and for helping!
