[Gleb Osipov]

For those who looking for, script to insert Latex Math into InDesign as SVG

Very clever.

Who runs the web site?

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.

Store the LaTeX code with the image on the page.

When the image is selected, load the LaTeX code into the palette.

Store baseline / position offsets for the image.

Loads of cools stuff.

Sorry man, didn't cheked on Windows, working on Mac. Nice idea and advise, thank you, will fix it!

Hi @Gleb Osipov , As @Kasyan Servetsky suggests, I use the current time in millisecs for generating unique names:

var n =  "Prefix_" + new Date().getTime();

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

[Gleb Osipov]

Try to open in browser latex.codecogs.com maybe it's blocked by provider, that why it's give you that message

[Peter Kahrel]

The site opens without any problem.

[Gleb Osipov]

I'm using this library github.com/grefel/restix to connect script to internet, maybe problem in it 🤔

This looks great @Gleb Osipov, thanks for sharing!

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

Good remark, thanks, I will add

[Peter Kahrel]

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.

[Gleb Osipov]

but if SVG inside the text block with the baseline what properties I shoud give it to? Otherwise it's aligned by the bottom line

This is in the EPS - when generated by MathMagic and others:

Highlited line is used by all kind of scripts to re-position linked image file vertically.

Take a look at this thread. The required properties are outlined there (just ignore the bits about padding, they're not relevant).

Alternatively, add the baseline value to the file name so that each user can use their own method to align the equation. I would prefer that, in fact.

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.

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

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