LaTeX support?

[DarkWater]

I just noticed a LaTeX icon.  When did you guys add this?   Does it support basically any LaTeX features?  I'm guessing it just passes the stuff in the tags off to LaTeX and then runs some stuff to output it as a PNG.  Wikipedia does the same thing.

 

Testing:

[tex]\begin{equation}2Al(s) + 6HCl(aq) \rightarrow 2AlCl_{3}(aq) + 3H_{2}(g)\end{equation}[/tex]

 

EDIT: You guys need to stop nl2br() from killing it. D:  I put it all one line to fix it for my little test, but otherwise it has <br /> in there.

I only bothered to post it here because that's where it was most relevant: http://www.phpfreaks.com/forums/index.php/topic,233363.0.html

 

What do you mean with nl2br() ruining it though?

Oh, I wasn't aware that we didn't need to put ourselves into an equation environment.  I used:

\begin{equation}

2Al(s) + 6HCl(aq) \rightarrow 2AlCl_{3}(aq) + 3H_{2}(g)

\end{equation}

 

To write the thing in the original post.  If run directly, however, it gives:

[tex]

\begin{equation}

2Al(s) + 6HCl(aq) \rightarrow 2AlCl_{3}(aq) + 3H_{2}(g)

\end{equation}

[/tex]

 

Because nl2br() passes through and adds <br /> in.  It's not a problem for one-liners I guess.

It's starts within an equation environment, so you don't need to do that. Moreover, it's passed as a query string to a parser which generates a PNG, so having multiple lines is not possible. You can, however, do this:

[tex]1+2=3[/tex]
[tex]5! = 120[/tex]

for multiple lines.
