SUMMARY

This discussion focuses on the ability to access and copy LaTeX source code from posts on the Physics Forums (PF). Users express a desire for a feature that allows copying the raw LaTeX code directly, similar to the edit functionality available on Stack Exchange. It is noted that while individual equations can be copied using right-click options like "Show Math As" or "Copy to Clipboard," the full post source remains inaccessible for editing after a certain period. Additionally, users highlight an issue where line breaks in the PF editor are doubled when pasted into other applications, such as Geany.

PREREQUISITES
  • Understanding of LaTeX syntax and commands
  • Familiarity with the Physics Forums platform
  • Basic knowledge of MathJax rendering
  • Experience with text editors like Geany
NEXT STEPS
  • Research how to use MathJax for rendering LaTeX in web applications
  • Explore the capabilities of the Physics Forums editor and its limitations
  • Learn about LaTeX command structures and common packages
  • Investigate text formatting issues when copying from web editors to local applications
USEFUL FOR

This discussion is beneficial for forum users, LaTeX enthusiasts, and anyone involved in academic writing or technical documentation who seeks to efficiently manage and utilize LaTeX code within online platforms.

I was hoping to copy whole posts, along with the LATEX code (not the rendered equations). One way I did it in the Stackexchange network is to toggle the edit page and copy the source code there.

Apparently posts by others in PF, even your own posts after some time, cannot be edited. It would be great if we could at least copy the source code, perhaps by toggling a page where the source code of the post can be copied, but not edited?

Thanks in advance! ##;))##

P.S. it appears that for every line break copied from the text in the PF post editor (press the enter key), it is multiplied by two when pasted into, for instance Geany. Why is there such a behaviour?

If you have the BB toggle set so the icons are red and you "Reply" to the post, do you see the raw LaTeX? I usually do...

By the way, if you just want to copy the LaTeX for a single equation rather than an entire post, just right-click on the rendered equation and select either "Show Math As >" or "Copy to Clipboard >" as appropriate.

That's a good way, unless the ##\LaTeX## code has some “hidden” code that MathJax executes but doesn't display. ##\require{physics} \require{newcommand} \def\jjmm{{j_1 j_2; m_1 m_2}} \def\jjjm{{j_1 j_2; j m}}##

But once you see the code, you will probably be able to guess that there is some more code hidden elsewhere in the post.
$$\begin{equation}
\ip{\jjmm}{\jjjm} = (-1)^{j_1 - j_2 + m} \sqrt{2j + 1} \begin{pmatrix}
j_1 & j_2 & j \\
m_1 & m_2 & -m
\end{pmatrix}.
\end{equation}$$

That's technically possible, but almost never used in actual posts.

Now I see the hidden code >u<
