Can't use SVG with multiple diagramms

[smennig]

If I use svg as output I can not include more then one diagram. Example:

\documentclass{scrartcl}

\usepackage{graphics}

% Enables inclusion of SVG graphics - 1:1 approach
% This is NOT the approach of https://ctan.org/pkg/svg-inkscape
% which allows text in SVG to be typeset using LaTeX.
% We just include the SVG as is.
\usepackage{epstopdf}
\epstopdfDeclareGraphicsRule{.svg}{pdf}{.pdf}{%
  inkscape -z --file=#1 --export-pdf=\OutputFile
}

\usepackage[output=svg]{plantuml}

\begin{document}
\begin{plantuml}
    @startuml
    class Car

    Driver - Car : drives >
    Car *- Wheel : have 4 >
    Car -- Person : < owns
    @enduml
\end{plantuml}

\begin{plantuml}
    @startuml
    class B

    A - B : drives >
    B *- D : have 4 >
    B -- C : < owns
    @enduml
\end{plantuml}

\end{document}

Ok renaming the PlantUMLJobname like \def\PlantUMLJobname{second} has worked for me.

\documentclass{scrartcl}

\usepackage{graphics}

% Enables inclusion of SVG graphics - 1:1 approach
% This is NOT the approach of https://ctan.org/pkg/svg-inkscape
% which allows text in SVG to be typeset using LaTeX.
% We just include the SVG as is.
\usepackage{epstopdf}
\epstopdfDeclareGraphicsRule{.svg}{pdf}{.pdf}{%
    inkscape -z --file=#1 --export-pdf=\OutputFile
}

\usepackage[output=svg]{plantuml}

\begin{document}
    \begin{plantuml}
        @startuml
        class Car

        Driver - Car : drives >
        Car *- Wheel : have 4 >
        Car -- Person : < owns
        @enduml
    \end{plantuml}

    \def\PlantUMLJobname{second}
    \begin{plantuml}
        @startuml
        class B

        A - B : drives >
        B *- D : have 4 >
        B -- C : < owns
        @enduml
    \end{plantuml}

\end{document}

Ist there a mecanism to automate this?

@smennig thank you for your solution. As a mechanism I would suggest:

\newcounter{PlantUML}
\def\UMLcountUp{\stepcounter{PlantUML} \def\PlantUMLJobname{PlantUML\thePlantUML}}

and call it after each \end{plantuml} or before every \begin{plantuml}

\documentclass{scrartcl}

\usepackage{graphics}

% Enables inclusion of SVG graphics - 1:1 approach
% This is NOT the approach of https://ctan.org/pkg/svg-inkscape
% which allows text in SVG to be typeset using LaTeX.
% We just include the SVG as is.
\usepackage{epstopdf}
% --export-type="pdf"
\epstopdfDeclareGraphicsRule{.svg}{pdf}{.pdf}{%
%example-component-diagram-plantuml-svg-converted-to
  inkscape #1 --export-text-to-path --export-filename=\OutputFile
}
\usepackage[output=svg]{plantuml}

\newcounter{PlantUML}
\def\UMLcountUp{\stepcounter{PlantUML} \def\PlantUMLJobname{PlantUML\thePlantUML}}

\begin{document}

    \begin{plantuml}
        @startuml
        () "Interface 2" as I2
        () "Interface 3" as I3

        [component 1] as c1
        [component 2] as c2
        [component 3] as c3

        c1 -- I2
        c1 -- I3

        I2 )-- c2
        I3 )-- c3
        @enduml
    \end{plantuml}
    \UMLcountUp

    \begin{plantuml}
        @startuml
        class Car

        Driver - Car : drives >
        Car *- Wheel : have 4 >
        Car -- Person : < owns
        @enduml
    \end{plantuml}
    \UMLcountUp
\end{document}

But it would be nice if something like:

\newcommand{\myplantuml}[1]{%
    \UMLcountUp
    \begin{plantuml}
        @startuml
        #1
        @enduml
    \end{plantuml}
}

could work...

[NWest09]

in the plantuml.sty you can change some parts... I'm not sure if you should, so all on your own risk.

Line 27 you can change to:

% \jobname has an encoding issue if the .tex filename includes a multibyte string.
% One needs to redefine PlantUMLJobname to fix it
\newcounter{PlantUmlFigureNumberSVG}
\def\UMLcountUp{\stepcounter{PlantUmlFigureNumberSVG} \def\PlantUMLJobname{PlantUML\thePlantUmlFigureNumberSVG}}
\def\PlantUMLJobname{\jobname\thePlantUmlFigureNumberSVG}

original line 96 (if you added the code above it will be line 98)

{
      \includegraphics[width=\maxwidth{\textwidth}]{\PlantUMLJobname-plantuml.\PlantUmlMode}
      \UMLcountUp
    }

Worked for me - you will have a mess in the build folder => be sure to clean up a little bit...

@NWest09 Looks good. Can you submit a pull request so that I can work on having the fix published on CTAN?

[NWest09]

I will work on Friday or Saturday to submit the code. (I'm not sure if I set up everything correct but I think so)
