General ⇒ lineno number caption w/ honor '\linenumbers'

[gallioleo]

Hello,

i like to use the lineno package to numbering my document. For numbering the caption I use the fix from 'https://tex.stackexchange.com/questions/579040/figure-caption-line-numbers-with-achemso-package?rq=1'

\usepackage{lineno}
\DeclareCaptionFont{linenumbers}{\internallinenumbers}
\captionsetup[figure]{font+=linenumbers} % use \internallinenumbers inside figure caption

This works also well, but to enable the line numbering i use the switch '\linenumbers'. With this fix the caption are always numbered w/ and w/o the line numbering enabling.

Does anyone has an idea, how i can number the caption with honoring the '\linenumbers' switch?

Thanks in advance.

Best Regards.

Without minimal working example I can only speculate. Maybe:

Code: Select all

\DeclareCaptionFont{linenumbers}{\ifLineNumbers\internallinenumbers\fi}

Here the MWE:

Code: Select all

\documentclass[
        pagesize=pdftex,
        12pt,
        DIV=14,
        paper=a4,
        final
]{scrreprt}


\usepackage[english]{babel}
\usepackage[hang,footnotesize,bf]{caption}
\usepackage[left, pagewise, edtable]{lineno}


% enable line numbers for caption
\DeclareCaptionFont{linenumbers}{\ifLineNumbers\internallinenumbers\fi}
\captionsetup[figure]{font+=linenumbers}


% Start Document
\begin{document}

\linenumbers

My Example text before figure

\begin{figure}[h]
	\caption{MyCaption}
\end{figure}

and after figure

\end{document}

The Compile result looks like follow:

Thanks for the code - great work! The other comment I'll honot also.
One hint the figure caption line has the same number like the line before the caption. This happends only if i use pagewise numbering. Do you have therefore a suggestion?

Thanks a lot again!

The problem is, that figure is a floating environment. The location of floats is not known before the output routine. So it I think it could be very hard to change this. I would not expect this to work. However, you could adjust the line number using \resetlinenumber, but only if you know, where the figure is placed in the output.

I'm even surprised, that line numbering in floats does work anyway.

So, no, I cannot help in this.

[gallioleo]

No problem, i switch to continous numbering and then did does not happen.

Hi again, for the tabular environment i like to use the same hook, but at the moment i fail to get it to work. Please take a look again:

Code: Select all

\documentclass[
        12pt,
        DIV=14,
        main=english,
        final
]{scrreprt}


\usepackage{babel}
\usepackage[hang,footnotesize,bf]{caption}
\usepackage[left, pagewise, edtable]{lineno}
