LaTeX Latex Command Window now available

[Greg Bernhardt]

Using Latex on PF has now never been easier! Thanks to the hard work of member https://www.physicsforums.com/member.php?u=40201". For the meantime I am interested in any performance issues you may have related to the feature.

Could this possibly be the best news of the year?

(I don't think so. The best news will of course be Latex preview.)

Good job, -Job-, and the rest of the PF team! I'm not sure if this is a bug... under 'Common Snippets' I see Distance Equation and Euler's Constant, but clicking either displays the word 'something' within tex tags.

 

[ranger]

Wow, this is awesome. I haven't tested thoroughly as I would like, but when I expand a category, I find that I cannot suppress it by clicking the minus sign. [Using firefox].

But its a nicely integrated feature. Thanks -Job-!

Edit: that's Sigma Greg.

\sigma\omega\epsilon\epsilon\tau !

 

[Doc Al]

x^{2} \neq \sum\left\{Y_{\alpha}\right\}

Not bad!

 

[billiards]

hello/yes this\triangleleftis fun

Now i just need to figure out how to use latex

 

[robphy]

Great work!

\alpha\beta\chi\delta\epsilon\phi\varphi\gamma
ABX\Delta E\Phi\Gamma
looks Greek to me... but not Greek-alphabetic order.
It looks more like English-first-letter-alphabetic order...
\alpha\beta\chi\delta\epsilon\phi\varphi\gamma

 

[berkeman]

What's a \varphi ?

\varphi

Oh, got it.

 

[FredGarvin]

This is very cool. Thanks Job!

This looks just like MS's equation editor that I use in Word. Is it related somehow?

I hadn't heard about that Fred. Is it a standard part of Word, or is it an add-in package?

 

[-Job-]

I would remove the common snippets group until it has some useful commands. I left it as pasting "something" because i couldn't remember the distance equation.

Also, you might find that some commands don't work in this forum, I'm thinking of the formatting commands, let me test that:
\LARGE hello, this doesn't work \footnotesizeor does it?

The reason for that would be because PF processes all LaTeX as if in a math region (am i right?), and the formatting commands don't work within a math region from my experience.

Also you might find that the reference is missing some LaTeX commands. I copied the list of commands used in TeXniCenter. If you come across some that are missing let me know so i can create icons for them and include them in the next release.

d\ =\ \sqrt{(x_{2}\ -\ x_{1})^{2}\ + \ (y_{2}\ -\ y_{1})^{2}}

 

[FredGarvin]

I hadn't heard about that Fred. Is it a standard part of Word, or is it an add-in package?

I can't say that it is standard, but it has been part of every version I have owned.

If you go to INSERT and then OBJECT, you will see in the list MICROSOFT EQUATION 3.0 (or similar). Insert it and the tool bar will pop up automatically.

I hadn't heard about that Fred. Is it a standard part of Word, or is it an add-in package?

It is an option available at installation for Office [including Word and Powerpoint], but it's not selected by default [at least in Office 97, 2000, and 2003]. With the installation media available, it could be installed when requested for first use. (So, those who make images for computer-cluster machines [for universities], please make sure you select it.)

 

[radou]

Wow, thanks -Job- !

 

[chroot]

Fantastic work, Job! You're a much better vB hacker than I am!

Maybe -Job- has some ideas about how to fix the Latex preview... :!)

 

[ranger]

I think Greg mentioned that having latex preview would create the burden of extra/wasted bandwidth.

 

[Doc Al]

I think Greg mentioned that having latex preview would create the burden of extra/wasted bandwidth.

That's too bad. But why would previewing Latex be any more of a bandwidth hog that actually posting the Latex? And the previewing is only temporary. Of course, I have no idea how preview works anyway! Guess I'll have to add that to the already large and growing list of things I don't understand.

 

[Greg Bernhardt]

I think Greg mentioned that having latex preview would create the burden of extra/wasted bandwidth.

Chroot thought of an idea to resolve this problem, so it's just up to him to start it :)

 

[-Job-]

So why doesn't latex render on the post preview again? I thought this was intentional by Greg and chroot.

I'm starting to develop another plugin for doing pretty much what chroot did for PF, which might take me another couple of months.

I have http://www.latexlab.org under development which can be used for previewing i guess, but in-site preview would be much better.

 

[chroot]

Yeah, sorry guys, I can fix the latex preview. I'm just swamped with school and work and all and haven't gotten around to it. Now that I know there's a huge demand for it still, I will try to get on top of it.

[robphy]

Does any know how it worked before?
And, possibly, where specifically it is broken?
Otherwise, it seems it's not asking for a fix but for a new solution.

[edit... I see that some replies have snuck in while composing][/color]

I think Greg mentioned that having latex preview would create the burden of extra/wasted bandwidth.

I recall this thread...
https://www.physicsforums.com/showthread.php?t=144652

In my opinion, \LaTeX support is very important. It is a feature that attracted me to PF.

I think that \LaTeX support while composing replies is also important... especially when it was feature that was available before. These days, I am less likely to post a reply to a post which could benefit from the use of \LaTeX because of the broken preview. If I am so compelled to compose an answer, I'll write it locally on my computer, then recode the tags for posting to PF... but that's sometimes proves too much trouble.

(While I'm on my soap box, I'd like to suggest support for SVG and for something like LiveGraphics3D (a .jar file from http://www.vis.uni-stuttgart.de/~kraus/LiveGraphics3D/ which could be hosted on the PF server)... as seen on MathWorld, e.g. http://mathworld.wolfram.com/Hyperboloid.html ) or possibly JavaViewLib for Maple http://www.javaview.de/maple/index.html )

Pictures are worth a thousand words.
Interactive animations or visualizations in 3D... are worth a lot more.

 

[chroot]

Okay, okay, I'll fix the preview. The 'problem' is that the hooks that vBulletin provides are not quite in the right places to make the preview easy to implement. I will work on it.

But...but you belong to PF. I honestly can't see how anything else is more important

 

[Thrice]

Bah I still think my tool works better :p

 

[chroot]

All right folks... preview's working again. I guess that wasn't as hard as I thought it'd be. I just had to find the right places to put the code. Sorry I didn't do it earlier.

we're back, baby!

Awesome! Thanks Warren and -Job-. You guys kick butt.

I'm starting to develop another plugin for doing pretty much what chroot did for PF, which might take me another couple of months.

BTW, the site currently uses nothing but four small hooks into vB, a couple of scripts on the server, and some standard Unix programs. It probably would be quite easy to package it up into a legitimate redistributable vB product.

On a related note,
I found this little "Google gadget" www.google.com/ig/directory?source=gapi&num=24&url=http://www.sitmo.com/gg/latex/latex.xml
which appears to interact with a website to interactively regenerate rendered-LaTeX as you type.

To use it without "adding it to your website [or to your iGoogle homepage]", go here: http://www.sitmo.com/latex/

It doesn't have as many symbols as -Job-'s great LaTeX Command Window... but the [probably server-intensive] interactive LaTeX rendering is cool.

This is \tau oo \gamma oo\delta!

Thanks a lot, X\rho oo\tau!


P.S. -Job-, the tex code for omicron is just o; \o displays phi.

Cool, nice Job!

Using Latex on PF has now never been easier! Thanks to the hard work of member https://www.physicsforums.com/member.php?u=40201". For the meantime I am interested in any performance issues you may have related to the feature.

At this moment there is no Sigma icon.
What happened?

It's there. It's just not available in every forum, apparently. (Such as this one.)
