如何覆盖逐字包中显示代码的行号

Question

我有一个代码块，我想使用 verbatim 包在乳胶中显示它，但我想自定义代码行编号，而不是从 1 开始。这是我所关心的乳胶代码的示例：

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}

\begin{Verbatim}[numbers=left,xleftmargin=5mm]

    //Initial matrix alignment for A and B
        int shift_source, shift_destination;
        MPI_Cart_shift(row_communicator, 0, -coordinates[0], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(A_local_block, A_local_block_size, MPI_DOUBLE,                                                      shift_destination, 0, 
                 shift_source, 0, row_communicator, &status);

        MPI_Cart_shift(column_communicator, 0, -coordinates[1], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(B_local_block, B_local_block_size, MPI_DOUBLE, 
                 shift_destination, 0, 
                 shift_source, 0, column_communicator, &status);

    // cannon's algorithm
    .
    .
    .
    .
    MPI_Finalize();
}
\end{Verbatim}
\end{document}

编译后的样子如下：

我想要启动 verbatim 包来开始对行进行编号，比如从 2​​00 开始，而不是从 1 开始。

有任何想法吗 ？

Answer 1

您可以指定该firstnumber选项。

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}

\begin{Verbatim}[numbers=left,xleftmargin=5mm,firstnumber=200]

    //Initial matrix alignment for A and B
        int shift_source, shift_destination;
        MPI_Cart_shift(row_communicator, 0, -coordinates[0], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(A_local_block, A_local_block_size, MPI_DOUBLE,                                                      shift_destination, 0, 
                 shift_source, 0, row_communicator, &status);

        MPI_Cart_shift(column_communicator, 0, -coordinates[1], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(B_local_block, B_local_block_size, MPI_DOUBLE, 
                 shift_destination, 0, 
                 shift_source, 0, column_communicator, &status);

    // cannon's algorithm
    .
    .
    .
    .
    MPI_Finalize();
}
\end{Verbatim}
\end{document}

另一种方法是verbatimbox：

\documentclass{article}
\usepackage{verbatimbox}
\begin{document}

\begin{verbbox}[{\rmfamily\tiny\the\numexpr200+\value{VerbboxLineNo}\relax}\quad\scriptsize]
    //Initial matrix alignment for A and B
        int shift_source, shift_destination;
        MPI_Cart_shift(row_communicator, 0, -coordinates[0], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(A_local_block, A_local_block_size, MPI_DOUBLE,                                                      shift_destination, 0, 
                 shift_source, 0, row_communicator, &status);

        MPI_Cart_shift(column_communicator, 0, -coordinates[1], &shift_source, &shift_destination);
        MPI_Sendrecv_replace(B_local_block, B_local_block_size, MPI_DOUBLE, 
                 shift_destination, 0, 
                 shift_source, 0, column_communicator, &status);

    // cannon's algorithm
    .
    .
    .
    .
    MPI_Finalize();
}
\end{verbbox}
\hspace{5mm}\theverbbox
\end{document}
