I find it very commendable that Adobe is implementing MathML into the program. It is a step in the right direction, even though the tool will not yet meet the requirements for scientific typesetting at the time of release. I see the following points as necessary to eliminate the need for third-party programs in the long term:

1. Editability of formulas with respect to text, color, spacing/kerning, line representation and line thickness, as well as glyph selection.
2. Introduction of (object) styles for formulas that store these settings, enabling more efficient workflows for extensive works.
3. Support for CMYK and spot colors for print output.
4. Editability of the formula in plain text for more user-friendly handling.
5. Proper tagging and passing of MathML code as alternative text for output in ePub and PDF/UA.

Yeah, I know.
But poorly at this time.
Good to listen, that you are about to continue implementation.
I wrote it as an advice - I am for example missing setting "100% of point size".
Thank you :)

MathML support proposed by Adobe is far from being the best solution!

I believe MathTools will continue to be better...

MathML functionality comes with a steep learning curve.

Unicode's Nearly Plain-Text Encoding of Mathematics offers a much simpler and more intuitive alternative.

I recommend checking out the following document for more details:
https://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v2.pdf

I'm happy to see that InDesign 20.0 now supports MathML, even if some functionnalities are missing.

The one I absolutely need is having access to the base line of the equation so that aligning it with the surrounding text becomes easy by script. That's what I do with equations from MathType (reading the line %%Baseline: .... in the EPS file).

We need this especially for accessible PDF exported from InDesign!!

A publishing tool without Math support is not convincing. Please consider providing Math (MathML) support.

@All: This is to update you that Adobe has integrated MathML support in the recent prerelease version and expecting to make it LIVE the initial version during MAX release, most probably by Oct'24 and confirmed that further upgrades will be made and do the DOT releases in CC 2025

Thank you so much all, who and all voted for this idea and shown that it's very much needed!

I do the layout of a lot of Theses so this would be extremely useful!

Bringing this into 2024: Adobe needs to see the math market + accessibility success this would have. To be able to host and easily update complex equations would open the door to a whole new user base of math documentation and textbooks. MathML (or even LaTex) plugin would be extremely beneficial in my workflow.

MathML Support would be very helpful

@Claudio Marconato, thanks for asking. I am afraid MathMagic is mentioned too often lately but I guess it is OK to answer you because this info is publicly available many places.

As you can find from the attached screenshot, MathMagic is available through InDesign's Plug-ins menu, or right-button clicked contextual menu, or InDesign's toolbar on the left bottom.

To add a new equation, you can simply select "New Equation". To re-edit an equation, you can simply double-click on it.
Inserted equation in a text box as an inline object will automatically align its baseline to the text baseline.
As explained below, MathML or LaTeX / Plain TeX and other info can also be converted or inserted.

If you need to change the font or size or other style of your equations in the whole InDesign doc or in a certain range or pages, a new Style can be applied to all those equations at once. For example, when your InDesign's body text need to change its font or size, all equations can also be changed accordingly quickly.

All equations are placed in EPS format so InDesign handles them natively. So you do not need MathMagic application or plugin installed, if you do not need to create or reedit equations. Your InDesign documents with MathMagic equations can be shared with other designers or printing service bureau without asking them to install MathMagic, and future versions of InDesign can handle the those equations even if MathMagic is not installed.

Overall, MathMagic should just work seamlessly, like a part of InDesign's builtin feature.
Hope this answered you.

@MathMagic Support, so with MathMagic Pro on macOS there's a good integration with InDesign?

@Raja, Gejaraj: Thank you. If you have a Mac, and would like to test the current MathMagic Pro on macOS, please send us a brief email to support@mathmagic.com. We would like to offer you an Evaluation copy.

@MathMagic Support: yes, it was tested long-back in Windows with trial version first and then bought 1 license (looking for the name of purchase as we changed our corporate name thrice later)

@Raja, Gejaraj
May we ask when you tried MathMagic because we could not find your name from our database for the last 10+ years.
Was it just a Trial version with limited features? Or, purchased under a different name?

@All: like to share the collective details on the challenges we're facing in different 3rd-party tools, please let me know, if anyone required additional details:

(1) PowerMath: Need to follow different coding structure than MathML or TeX/LaTeX, outdated and our client is requesting not to use this plug-in for their projects

(2) MathMagic: Explored this, but not up to the mark, challenges in hanging and much more, also cost is much higher than InDesign license cost

(3) InMath (then) / MathTools (now): Few clients preferred this and now dropped due to less support, not user friendly, licenses getting inactivated frequently, also cost is much higher than InDesign license cost

(4) MathType: Currently using for many of our clients, but challenges in handling complex equations, also rendering as images, due to that difficult in setting the equations across the pages and spreads, MathML extraction not up to the mark and much more

So finally, Adobe should have in-built MathML support to cover all the possibilities and without the above mentioned challenges.

无法相信，作为一个排版软件，迭代了这么多个版本，居然还不支持公式，现在在线文档编辑器几乎都是标配了。
I can't believe that as a typesetting software, after iterating through so many versions, it still doesn't support formulas. Nowadays, online document editors are almost standard.

We need this!

Please make sure the Smart Quotes are not enabled and not used in the MathML expression.
