Operating System

Linux 6.4.3-1-default (amd64)

TeXiFy IDEA version

0.7.32

Description

This error happens when I'm trying to preview $\tau = 0.5$

When I try to preview
\begin{equation}
\tilde{g}{tot,i} = \tilde{g}{s,i} + \sum_{j} P_{rel,i,j} \tilde{g}_{mod,i,j}

I'm told: Unknown environment: equation at position 1:1

I don't know about the exception, but I can't preview that either, I guess because jlatexmath doesn't have the equation environment loaded.
As a fallback option you can use the roundabout way using inkscape, see https://hannah-sten.github.io/TeXiFy-IDEA/tool-windows.html#equation-preview

This works for me:

\documentclass{article}
%! Begin preamble = math
\usepackage{amsmath}
%! End preamble = math

\begin{document}
    
    \begin{eqnarray}
        \tilde{g}{tot,i} = \tilde{g}{s,i} + \sum_{j} P_{rel,i,j} \tilde{g}_{mod,i,j}
    \end{eqnarray}

\end{document}

I have three issues with this solution:

• I do not want to change the environment, especially since
• the use of eqnarray is discouraged.
• When trying to display the preview with this exact MWE, I get another error: Can't read input file!
  Actually also when trying to display other environments.

You should be able to use any environment from amsmath with the above example. If it doesn't work for you, please start a new discussion/issue with more details so we can help you!

Wait I can reproduce the problem actually, let's discuss in #3314
