Latex to SVG / InDesign Script

Do you have user instructions? I can't get it to produce anything at all in InDesign.

Wonderful. Would be even more wonderful if user can select Inline or Block. One can select on the editor page. https://editor.codecogs.com/

Not sure about the Mac's side - don't know the environment - but if you are interested, the Window's part can be literally converted to just two lines of code. 

Pickory raises a good point: you need the equation's baseline so that when it's placed as an inline equation, e.g. 'ln', 'x', and 'C' sit on the baseline of the line it's on. Without baseline information, the SVG sits too high, with its bottom on the line's baseline.

This looks great @Gleb Osipov, thanks for sharing!

Could you add a check for when the active document has never been saved?

I get a different error message: 'Failed to connect to latex.codecogs.com'.

Wow! Very cool! Thanks for sharing this, Gleb.
On my side -- on Windows --  this line throws an error:

var svgFileName = latexCode.replace("/[^\w\d]/g", '');

because it fails to make a valid file name from a formula.
I suggest changing it to, say, a prefix plus a randomly generated number, like so:

var randomNum = Math.random();
randomNum = String(randomNum);
randomNum = randomNum.replace(/^0\./g, "LtxEqtn_");
var svgFileName = randomNum;

I think it's hardly possible that the same number would be generated twice overwriting an existing formula.

Or, even better a unique date string: up to secs.

Very clever.
