Hi everyone,

Below is a video of a talk by John Hudson (of Tiro) pondering variable
fonts for stretchy constructions (the part starts around 43 min into the
talk though the link should take you there).

I've reached to John to get more input on this ideas.

Best,
Peter.

Hi Peter,

My wish list:

specification.

2) [CSS] Still interested in Math layout (with or without the help of
MathML).

During the year, for sure more ideas will arise!

## [MathOnWeb] what do you expect for 2019?

Source: public-mathonwebpages@w3.org Mail Archives • Peter Krautzberger (peter@krautzource.com) • January 10, 2019 • Permalink

Hi everyone,

As we did last year, let's try for a thread with thoughts on the coming
year and what we might focus on within this CG.

I'll start below.

Best,
Peter.

I think 2019 will be a difficult year for the CG. The main problem is the
recently re-opened arguing around "native" MathML support in browser. I
expect this to continue to have a negative impact on this group and the
wider community.

I wished there was an easy way to make a clear cut and simply have all
"native" MathML fans take it elsewhere. But there isn't. Too many people
(myself included) consider MathML a useful spec to capture print layout in
an XML context (and thus critical for legacy content) and for them it will
be difficult not to care if the spec ends up being damaged in another
attempt to "bless" problematic browser implementations (remember Presto?).

The second and sadly related problem is that the number of active group
members has dropped recently. As Tzviya likes to say: standards are made by
those who show up - and people aren't. Some of this has to do with the
constant arguing around MathML. Since math on the web is a very small niche
(and that won't change), there are very few people willing and able to work
towards standardization, and even fewer who can afford to spend their time
on standards work. I would like to encourage everyone on this group to be
more mindful of this.

What could the group work on in its current state? Some ideas:

1) Being a good space for the community. I was surprised with how often the
CG telcos end up helping individuals who show up one time. I think the
group can do more to be a place where the community gathers openly.

2) The accessibility task force has mostly joined the ARIA WG directly.
That's a good move for now to keep things focused while moving up in the
standards process. My personal favorite would be to get separate Braille
streams moving forward but ther are other ways to make a positive impact on
the web platform this year.

3) The CSS task force had a productive meeting with the CSS WG at TPAC and
if there's progress on even a single item from our TPAC list it would be a
significant step for the web as a whole.

4) Given the recent news about AsciiDoc working towards standardizing its
syntax, I'd like to try to re-open the linear notation task force. I could
imagine both AsciiMath and TeX-style syntax for the web could benefit from
some standardization.

5) I would also like for the CG try to live up to its scope which is all
mathematics (and possibly large chunks of scientific content) are part of
it. Equation layout is a solved problem (even if separate braille streams
are still on the todo list). Let's stop obsessing over it and think about
other content or technologies (e.g., computational improvements to the web
platform). I plan to follow up on my theorem-related posting a while back
and perhaps other people have topics they're itching to discuss more

Alright, that might be a decent start.

Best,
Peter.

Hi everybody,

Since no one took minutes, I write what I remember during the
teleconference. It might be some bias from my side.

Dani

# A11y TF

Present: Kevin and Dani

A brief meeting where Dani pointed out that most of the work should be done
inside the Aria WG and only use the TF if some additional work is needed.
Unfortunately, only invited experts or affiliates of the w3c organization
members can take part of the Aria WG meetings. We will update at the
regular CG meetings.

# CSS TF

Present: Arno, Peter and Dani

We discussed basically two topics.

We decided that it is fine to update the document
https://github.com/w3c/mathonwebpages/wiki/%5BCSS-TF%5D-TPAC-2018-preparations
since TPAC was finished.

We discussed a little bit the options for the CSS specification of the
stretchy character
. No decision was made about which is the best option. Arno pointed out
that CSS functions are “functions” and that should “return” a well known
object with proper type, so they shouldn’t be used as a mere syntax
constructor. We decided to start some implementations and we will see which
specification we want later.

## ARIA and Assistive Technologies Community Group

Source: public-mathonwebpages@w3.org Mail Archives • Daniel Marques (dani@wiris.com) • December 05, 2018 • Permalink

Hi everybody,

Recently the following community group was created:
ARIA and Assistive Technologies Community Group

That seems relevant to the tasks we do in the MathOnWebPages CG since many
times we face the scenario where a feature is supposedly available in ARIA
but, then, the AT behaves in an unexpected way. For example, aria-label
does not override the text of an element.

For that reason, I suggest you join the ARIA and Assistive Technologies
Community Group. <https://www.w3.org/community/aria-at/>

Dani from WIRIS

## MathJax v3 beta.3 released

Source: MathJax • November 28, 2018 • Permalink

The MathJax team has been working hard on a major rewrite of MathJax from the ground up, with the goal of modernizing MathJax’s internal infrastructure, bringing it more flexibility for use with contemporary web technologies, making it easier to use with NodeJS for pre-processing and server-side support, and making it faster to render your mathematics. We have made headway in all these areas and we are pleased to announce the third public beta release of MathJax v3.

## Where to Find the Beta Release

The code for the release is available in the beta branch of the MathJax v3 github repository.

Examples of how to use MathJax v3 in web pages are available in the mj3-demos repository. This includes several pre-packaged versions of MathJax for common use cases (e.g., converting TeX to HTML in a web page) that you can link to for your own test pages, along with sample HTML pages that call them and documentation on how to configure MathJax v3. There are also instructions on how to make your own custom webpacked version of MathJax v3.

Examples of how to use MathJax v3 in NodeJS are available in the mj3-demos-node repository. These include samples of how to convert a TeX string to an HTML string, an SVG string, or a MathML string, for example, or how to process a complete HTML page containing math.

## What’s Included in MathJax v3

This beta version includes two input processors (TeX and MathML) and two output processors (CommonHTML and SVG). Other input and output processors (e.g., AsciiMath input) will be added in the future.

The current TeX input processor has all the core functionality of the MathJax v2 TeX input, and nearly all the extensions are now available in v3.

The CommonHTML and SVG output implement all the MathML elements that they do in v2, but do not yet include support for line breaking (neither automatic nor explicit ones); this will be implemented in a later beta version. Both output renderers currently only support the MathJax TeX font; other fonts will be added in the future.

The CommonHTML output currently uses a very large CSS file that encodes the font information needed for all the characters in the MathJax TeX fonts. This is a preliminary implementation of the font support, which will be updated to reduce the size of the CSS in future versions.

The SVG output currently uses explicit SVG <path> elements for the characters it displays, whereas version 2 cached the paths in a common SVG <defs> element so that paths didn’t have to be repeated in the individual expressions that used them. This will be implemented in a future version.

The MathJax contextual menu is not yet implemented.

The ability to customize MathJax through a configuration object, as in v2, is limited at the moment, but see the mj3-demos repository for examples of how this can be done currently. In version 3, this type of customization is handled through building custom packed versions of MathJax, and that is not yet fully documented; again, the demo repository includes examples.

## What’s New

This release fixes a number of display issues with the SVG output (see #153, #156, #157, #137) and improves the output for nested tables, particularly those with labels and those with percentage widths, in both CommonHTML and SVG output. Problems with table lines in SVG output in Safari and IE were fixed as well.

The TeX input has been updated to include nearly all the extensions that were available in v2, including the color, action, unicode, bbox, html, and several other extensions. These are all included in the webpacked files available in the demos repository (listed below), although the color extension is not enabled by default in order to preserve the behavior of \color in version 2 (this will probably change in the official release of v3).

In addition, there were some changes internally to how the MathDocument and MathItem classes, and the Handler class now allows more flexibility in overriding these. These changes are needed to better support extensions that may need to subclass the document and math-item classes. The next release will formalize the extension mechanisms and will include examples of how extensions will operate.

Finally, the TeX-lab.html and MML-lab.html files have been merged into a single v3-lab.html, and the original files removed. This late allows you to experiment will both input and both output formats, as well as enable/disable each of the extensions individual.

## NOTE

Mathjax v3 is in beta release. Do not use this in production, but please test it and report issues on the MathJax v3 issue tracker!

We are continuing to add more functionality to version 3, and will be releasing additional beta versions as new features become available. So watch this site for more news to come!

Hi everyone,

Here are the minutes from the meeting of the CSS task force this week.

Best,

# Math On Web CSS TF, 2018-11-19

* Present: Dani, Peter
* Peter: do we just point them to the spec we found?
* Dani: not enough, we need to align at child still
* same for mathaxis
* Dani: next steps?
* Peter: hoping Arno might have more suggestions from the rest of TAPC
* https://github.com/w3c/csswg-drafts/issues/1339#issuecomment-300293130
* tabatkins and fantasai agreed there
* parent has "I have special baseline"
* child has "I'm the baseline"
* Dani: I ran into the following: what if multiple children say "I'm the
baseline"
* Peter: oh, good problem.
* could we find CSS specs that might have a similar problem?
* eg. subgrids -but two subgrids don't create conflicts.
* Dani: then there's looking through baseline container, finding a child
that is baseline container
* seems like it should stop looking?
* Peter: eg nested fractions
* Peter: yes, unless this child is itself a baseline container
* bottom up: the child informs the parent but that parent might inform
its parent etc
* [some discussion around this]
* Peter: in terms of what to do with multiple children declaring
baselines, we just choose first or last and let CSS WG say what they prefer
* Dani: maybe we should continue the thread with this
* Peter: sounds good.
* Dani: then what's next?
* Peter: after discussion with Arno, maybe a Houdini-based polyfill
* before going to a C++ patch example
* Dani: Houdini is a bit different though
* basically, "this box has a completely different layout"
* Peter: I need to read up :)
* Dani: but seems doable
* maybe we can file an issue
* we probably need to come to an agreement whether border glyphs are good
enough
* Peter: I don't mind either way, I think border glyphs have independent
use cases and any implementation opens up the path to the other
* if they're interested, I'd put our foucs there
* Dani: sure but perhaps other options are just as interesting
* we should at least try
* [some discussion]
* Dani: ACTION let's gather some ideas (eg. in a google doc)
* be creative, figure out what we can do
* we need to figure out
* [some discussion about stretchy vs size switching]

# Math On Web a11y TF, 2018-11-19

* Present: Dani, Peter, Joanie, Charles, Sina,
* Dani: at TPAC, there was a discussion about joining ARIA
* Joanie: still with Michael
* due diligence check necessary
* what's the status?
* Peter: Arno is "retired", Volker not associated, is already invited
expert for svga11y I think, I was an invited expert at PWG/DPUBIG until
recently
* Joanie: ACTION will follow up
* Sina: ping as well
* Dani: who wants to join this work? Seems like a lot
* Joanie: my plan was to say "have math stuff once a month" to reduce load
* Dani: sounds good.
* Peter: I didn't have time to write up stuff on the walker stuff
* Sina: what's the link again?
* Peter: https://krautzource.github.io/mathjax-sre-walker/
* added a note that this demo needs ES6 modules (for dev ease, not
production)
* Sina: what platform works?
* Peter: Firefox, Chrome with NVDA is good, JAWS ok
* Joanie: FF+ORCA seems good [use Fedora 28 not 29]
* Sina: what came up at the TPAC meetings?
* Peter: just the Monday meeting as part of APA
* Peter: there should be minutes somewhere...
* Charles: https://www.w3.org/2018/10/22-apa-minutes.html#item02
* Peter: we went through
https://github.com/w3c/mathonwebpages/wiki/%5Ba11y-TF%5D-TPAC-2018-preparations
* APA was generally positive in response
