I think we can solve this issue by looking at how Wikipedia does the alignment of text and LaTeX snippets. A cursory look at https://en.wikipedia.org/wiki/Normal_distribution ... shows that they use something like this: <img src="..." style="vertical-align: -0.838ex; width:5.663ex; height:2.676ex;"> The alignment parameters are also dependent on the snippet itself. > If we could somehow fix that, MathJax-less export > could become usable in practice *and* it would also unlock full LaTeX > power, including TikZ and beyond! (It would also put Emacs ahead of the > pack in the world of LaTeX-capable editors because virtually every other > modern editor, including the proprietary ones, can just use MathJax.) For me, Emacs using MathJax as default came across as an unpleasant surprise: any person aware of the free/libre software movement knows that one should never allow Javascript to run in their browser: (ref https://www.gnu.org/philosophy/javascript-trap.html ). MathJax is not even compatible with LibreJS and loads script from a bunch of 3rd-party servers like Cloudflare. This enables those 3rd parties to track visitors to your website. Also, by loading external scripts, author of an website essentially puts the website and its visitors under the mercy of the script: the script, if malicious, can just sabotage the entire website. Sadly it seems that there aren't enough people using Orgmode with SVG: this CSS bug is at least present since 2020, according to git logs. Rendering SVG images is also painfully slow: I can export the document as PDF much faster than as HTML+SVG. Then there is the alignment issue. > @me.com Unrelated but I think its best to not use Apple dis-services: it has a record of kowtowing to government requests such as moving email account to surveillance-friendly regimes: https://en.wikipedia.org/wiki/ICloud#China Not to mention its utter contempt of Software Freedom such as forbidding GNU GPL on their program distribution platform. -- Yuchen Guo ^ permalink raw reply [flat|nested] 12+ messages in thread

As soon as the user adds a simple "$1 + 1 = 2$" to their Org document, the HTML export from Emacs/Org becomes quietly tracked by an American company. Emacs should never do that, IMO. [I decided to CC RMS on this issue.] (On a related note, the Emacs/Org manual mentions, "if you are following a system like David Allen's GTD", implicitly promoting a book that the publisher distributes just with mandatory DRM [1].) [1] https://orgmode.org/manual/Stuck-projects.html Agreed 100 percent with everything else you said. Further, in addition to the ethical issues, MathJax also makes the website render slower. With SVG, mathematics appears instantly, like on Wikipedia. > Unrelated but I think its best to not use Apple dis-services: [...] Definitely, and thank you for the reminder. The address dates back to when I still used Apple services. These days, I do not use them for personal purposes anymore, except for their IMAP server to fetch the messages.

MathJax is not the default export option. See org-html-with-latex 2. We use MathJax script from https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js It is licenced under Apache 2.0, which is GPL-compatible according to https://www.gnu.org/licenses/license-list.html#GPLCompatibleLicenses > (On a related note, the Emacs/Org manual mentions, "if you are following > a system like David Allen's GTD", implicitly promoting a book that the > publisher distributes just with mandatory DRM [1].) > > [1] https://orgmode.org/manual/Stuck-projects.html Emm. No? One can simply read https://en.wikipedia.org/wiki/Getting_Things_Done and free references from there. The fact that GTD methodology is described in some DRM-protected book does not imply that one must use that particular book to learn GTD. It would only be an issue if Org manual contained a direct link to David's book. Best, Ihor ^ permalink raw reply [flat|nested] 12+ messages in thread

My fault. You are right. I missed that `org-export-with-latex' is a variable, not a symbol. If you think that we need to change the default, feel free to open a new thread proposing an alternative. >> 2.

You can see it by following the script url. It is right on top. The other question is why LibreJS does not recognise the license. Maybe LibreJS can fix it on LibreJS side or maybe we can indicate that MathJax is GPL-compatible on the html page itself (https://www.gnu.org/software/librejs/manual/html_node/Setting-Your-JavaScript-Free.html) For the latter, patches are welcome. > - It is not trivial to `control your computing', as in `modifying the > script and run your modified copy instead.' I am not sure what is the problem here. Apache licence does not restrict modifications and you can use your modified MathJax source by customising org-html-mathjax-options.

Oh, I meant the freedom of the website visitor replacing MathJax with a modified version on-the-fly, not of the website authors. That is not trivial. Thanks for the tip!

I understand the problem, however I do not see why LibreJS could not whitelist MathJax.

To clarify, software freedom has little to do with privacy. Currently, ox-html does comply with https://www.gnu.org/prep/standards/standards.html Of course, it does not mean that privacy should be ignored. If you have any ideas or patches that can improve the current situation with the mathjax coudflare link, feel free to share them. >> I am not sure what is the problem here.
