It goes without saying that we shouldn't have to do this. This has been two months now.fresh_42 said:

I have a couple of freelance Xenforo devs working on this and struggling with the new editor. Xenforo 2.4 (out in a few months) will switch to yet another editor. Maybe that is a good thing. @PeroK I would love your support as a programmer. Please DM me and it would be great for you to have a look. Thanks!!PeroK said:
Also I just got word that MathJax 4 is coming out soon. I'm sure that will change things.

Another LaTeX issue:
Since last September I have been exchanging PF direct messages with @fluidistic regarding a problem he is interested in. I just went back to review them and although the messages clearly include raw LaTeX code, none of them actually render LaTeX equations anymore, no matter how often I refresh my browser page. That behavior is distinctly different from posts in PF threads which properly display LaTeX after refreshing the post (as long as you never use Preview prior to posting). Frustrating.

Update: @Greg Bernhardt promptly fixed the issue. All my messages now properly render their LaTeX content.renormalize said:

One other possible workaround is to keep a dummy insight around. Latex preview in Wordpress works just fine. When done, cut and paste to your reply.PeroK said:

Yeah, but it has another big disadvantage: Do not do this with an existing WP text!PAllen said:
I was tempted to repair a broken link today. No big deal within WP. However, whenever you do this (any update) then it automatically destroys the corresponding OP of the PF thread! Hence, I had to decide: keep that broken link, or figure out where the corresponding PF thread is, which by itself is difficult enough, then enter the edit mode, enable the BB mode, copy the entire text to somewhere, then make your update, go back to that thread, enter edit mode again and delete the nonsense that has been created by your update, and insert the saved text again.
Well, I did not repair the broken link.

Can you clarify? I see you would never want to use a posted insight; that's why I suggested a dummy (draft) insight. Once the latex issue is solved, get rid of the dummy draft. Do you see any problems with that?fresh_42 said:
- 20,819
- 28,465
No. I just wanted to point out that the update function on WP has a very negative impact on the corresponding thread on PF. A dummy thread is ok. You just shouldn't use an existing one.PAllen said:

A latex preview update is shipping soon. Need to walk the dogs first :)

Dang this is weird. It's working great on CivicsWatch, but here, it auto renders in the editor outside of preview.

##\begin{pmatrix}a&b\end{pmatrix}## is a vector.
[itex]\begin{pmatrix}c&d\end{pmatrix}[/itex] is a vector.
$$\begin{pmatrix}e&f\end{pmatrix}$$ is a vector.
[tex]\begin{pmatrix}g&h\end{pmatrix}[/tex] is a vector.
CW: No preview anymore at all.
PF: Inserting "amp;" stuff at the ampersand.
Hint @all: The {align*} statement has now to be put into double dollars. The previous version recognized them automatically as math.

Works now.Greg Bernhardt said:

Only copying this code directly from post #44 on the screen by Ctrl+C inserted some <br> and amp; and the preview ignores the carriage returns within the following code tags.
Code:
##<br>\begin{pmatrix}a&b\end{pmatrix}<br>##<br><br>[itex]<br>\begin{pmatrix}c&d\end{pmatrix}<br>[/itex]<br><br>$$<br>\begin{pmatrix}e&f\end{pmatrix}<br>$$<br><br>[tex]<br>\begin{pmatrix}g&h\end{pmatrix}<br>[/tex]Not anymore. I had testedGreg Bernhardt said:

\begin{align*}
1&=-1\\[16pt]
0&\neq 1
\end{align*}\begin{align*}
1&=-1\\[16pt]

and it wasn't recognized automatically as math code, but now that I tested it again, it does (as in the previous version).

This was directly after I posted it correct, but now it looks broken. Strange.fresh_42 said:

Testing inline ##\Omega=ab\mu^{\nu}\text{ test}## code. Testing display$$\Omega=ab\mu^{\nu}\text{ test}$$code.
Both inline and display tags now work reliably for me in preview. Eureka!

Let's see.
\begin{align*}
\begin{pmatrix}1&0\\0&1\end{pmatrix}&=\mathbb{I}_2
\end{align*}
results in ...
a) no preview at all
and then corrected to
$$
\begin{align*}
\begin{pmatrix}1&0\\0&1\end{pmatrix}&=\mathbb{I}_2
\end{align*}
$$
resulted in ...
b) a correct preview, and (sic!) it also previewed the first version without math tags correctly this time. But it did not on the first attempt. (I have no idea why.)
So now we will see what happens after hitting the post reply button.
Edit 1:
c) Page refresh is necessary
Edit 2:
d) Still, both versions are correct.
See what will happen after a while and/or leave the page.
Edit 3:
e) No additional amp; notes this time. I don't know what happened the first time.
I try to do it with the same code again:
##\begin{pmatrix}a&b\end{pmatrix}##
[itex]\begin{pmatrix}c&d\end{pmatrix}[/itex]
$$\begin{pmatrix}e&f\end{pmatrix}$$
[tex]\begin{pmatrix}g&h\end{pmatrix}[/tex]
f) Ctrl+C still copies the additional commands <br> and amp; into the buffer.
g) The preview is correct.
General observation from other threads: the quoted texts do not resolve TeX commands.
I close the edit session now.
Edit 4:
h) The post has been displayed correctly (after one refresh).
i) After the second refresh, I have again the amp; tags on the screen.
j) This occurs only in the lines that used [ tex ] and [ itex ] commands, not on the lines with hastags or dollars.
Code:
\begin{align*}
\begin{pmatrix}1&0\\0&1\end{pmatrix}&=\mathbb{I}_2
\end{align*}\begin{pmatrix}1&0\\0&1\end{pmatrix}&=\mathbb{I}_2
\end{align*}

The motional emf across an oriented segment ##d\mathbf l## is $$d(\text{emf})=\mathbf E\cdot d\mathbf l= (\mathbf v\times \mathbf B)\cdot d\mathbf l.$$Now $$\begin{align}& \mathbf E=(\mathbf v\times \mathbf B)=(\boldsymbol{\omega}\times \mathbf{r})\times\mathbf B \nonumber \\& = \mathbf B\times(\mathbf {r}\times \boldsymbol{\omega}) \nonumber \\& =\cancelto{0}{\mathbf r(\mathbf B\cdot \boldsymbol{\omega})}-\boldsymbol{\omega}(\mathbf B\cdot \mathbf r) =-\omega B r\cos\!\theta ~\mathbf {\hat y}.\end{align}$$
I had to change all & to just &.
Looking good! Thanks Greg.

I assume that it doesn't render in any tags.
