Show which float shows a warning message about vimtex HOT 4 CLOSED

First of all, thank you for making such a good plugin, it's already the third (or maybe fourth) year that I enjoy writing in Latex with the great help of vimtex.

Is your feature request related to a problem? Please describe it.

Currently, when the float specifier changes (e.g. from h to ht), the error message does not specify which float changed it. The warning message just says main.tex|| LaTeX Warning: `h' float specifier changed to `ht'.

This is very hard to improve on. The problem is that there is no line number information in the log file. Consider this:

\documentclass{memoir}
\usepackage{graphicx}
\usepackage{blindtext}
\begin{document}
\blindtext[4]
\begin{figure}[h]
    \begin{center}
        \includegraphics[width=0.95\textwidth]{example-image-a}
    \end{center}
    \caption{dasdasdas}\label{fig:qwe}
\end{figure}

    \end{center}
    \caption{dslkadjaslkdj}
    \label{fig:SpinDistributionModel}
\end{figure}

\end{document}

(Notice the use of example-image-[ab], which is a nice little builtin feature.)

Now, if we compile, we get the following output (more or less):

The warnings are not really directly related to the info about the "example-image-… used on input line X", and as you see, there is not other info.

If I knew a way to get the necessary information, then I might consider trying to make it work better. But I don't, and I've never heard of something like that before.

I'm closing, but feel free to continue the discussion. In particular, if you have any ideas, feel free to share.

Yes, these log messages are indeed difficult to parse. And I've had the messages related to one float separated by the other log messages. I suppose there is no clear way to implement a stable method to deduce the exact float.

I am not sure what the log parser can do, but maybe there is a way to implement a jump to the position of the message in the log file, instead of just jumping to the beginning of the main file?

I can see how using e.g. the line number of the previous entry could be convenient, but I'm skeptical. I believe it would be confusing to people that don't know of this behaviour.

I think the way to implement this is to enrich the relevant quickfix entries after the log file is fully parsed, similar to what we do here:
