LaTex for EEVBlog
« on: February 09, 2016, 04:44:17 pm »
there is a chance to enable LaTex support for the EEVBlog ?, I have a small blog and I'm using mathjax, is very very easy to use, only have to edit a template on blogger and that's it, probably more complicated here, but could be very handy and worth the effort.

Although, I think this particular subject has been raised before and the response was lukewarm. :(

LaTeX? Hell, just having unicode would be nice, so you could actually use a micro or ohm symbol. That hasn't happened either, though, so don't hold your breath for mathjax :(

I'd rather have a canvas. Some years ago I searched such thing for a site I have, but only found a plugin that would let you either write or have the canvas, but not both. Don't know what exists today.

I can't install it:

I get an error and ti warns me not to install. It's a 6 years old mod.

seems to be another approach for this:

http://www.simplemachines.org/community/index.php?topic=535624.msg3805548#msg3805548

only you have to edit a template files and that's it, no mod at all, refer to attached images for reference, one from simplemachines forum, another from mathjax documentation, and finally how I did it to enable LaTeX.

A pity, the reason for the error seems to simply be a pretty minor formatting issue. Just different enough to not work.
If you're going to go to the bother of manually fixing things it doesn't really seem worth it for something six years out of date.

seems to be another approach for this:

http://www.simplemachines.org/community/index.php?topic=535624.msg3805548#msg3805548

This seems to work really well. It does seem to require manually including the script, but I would be surprised if there was a mod available to make that easy.
I'd  recommend using
Code: [Select]
<script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [['\\$','\\$'], ['\\(','\\)']]}});
</script>

<script type="text/javascript"
  src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

so \$math\$ is inline as well as the default \(math\). This is just a personal preference, but it seems the most like native LaTeX that doesn't wreak havoc when single $ signs are used.

I bet you had problems with the 'async' attribute, if it was, you can solve it in this way:

Code: [Select]
<script type="text/x-mathjax-config">
    MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']]}});
    </script>
    <script type="text/javascript" async="async"
      src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_CHTML">
    </script>

I didn't have problems, I was just using a trivial file to play with the script. I agree that async might be a sensible addition.

I'd advice against using inlineMath: [['$','$']] as sentences like " $10 each, or three for $25", or whatever, will become unreadable.

you're right about the inline delimiter, the problem is I have to change all the LaTeX references in the blog |O, so, work for night late.

thanks for the tip.

Dave, on the off-chance that we can persuade you :

Looks like there is a mod that makes this really easy :  http://custom.simplemachines.org/mods/index.php?mod=2686.

Once it's installed you get a new option under "Admin->Configuration->Modification settings->Custom </head> and </body> Scripts".  Just past
Code: [Select]
<script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [['\\$','\\$'], ['\\(','\\)']]}});
</script>

<script type="text/javascript" async="async"
  src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>
Hit save and it should be done.

 I just tested it on SMF 2.0.11 (clean install just for this) and it works like a charm. Obviously there's always a chance that it'll conflict with some other mod you have installed, but it doesn't seem likely.

Done.
I have no idea how to test it.

Awesome, thank you. It seems to work just fine.

A slightly more complex test: \[\chi=<{m}>+<{m}>^2\left(\frac{\tau_c^2}{2T^2}\left[exp\left( \frac{-2T}{\tau_c}\right)-1+\frac{2T}{\tau_c}\right]\right)\]

I was working on it too to see what got supported.


Tex
The quadratic formula is $$-b \pm \sqrt{b^2 - 4ac} \over 2a$$ \bye

Latex
E &= \frac{mc^2}{\sqrt{1-\frac{v^2}{c^2}}}

AsciiMath
sum_(i=1)^n i^3=((n(n+1))/2)^2

A couple of simple examples to show how to use \$\LaTeX\$ in forum posts.

Code: [Select]
In line math \$R=123\mu\Omega\$ is done with dollar signsIn line math \$R=123\mu\Omega\$ is done with dollar signs


Code: [Select]
Display math \[P=\frac{V^2}{R}\] is done with square brackets.  Display math \[P=\frac{V^2}{R}\] is done with square brackets.

N.B. Anyone running a javascript blocker like NoScript, will need to add an exception for cdn.mathjax.org

$${\LaTeX}$$

$$ \newcommand\T{\Rule{0pt}{1em}{.3em}}
\begin{array}{|c|c|}
\hline X & P(X = i) \T \\\hline
  1 \T & 1/6 \\\hline
  2 \T & 1/6 \\\hline
  3 \T & 1/6 \\\hline
  4 \T & 1/6 \\\hline
  5 \T & 1/6 \\\hline
  6 \T & 1/6 \\\hline
\end{array}$$

MathJax doesn't implement tabular, because it is really a text-mode environment. You can use the array environment as a replacement. Source

Hey, thats a nice addition!

However it is so long ago that I used it... 1989 my Diploma Thesis and 1999-2009  for writing my book the first three editions (then we switched to "Word" and Indesign....gnaaaa.). In case you wonder: http://blenderbuch.de/ (be warned, pesky german).
