Embed Series

This plugin is an upgraded version of the Pseudocode Widget (siyuan-pseudocode), and serves as the second plugin in the Embed Series, aiming to provide a more complete and flexible Pseudocode experience within SiYuan.

The principle of Embed Series plugins: They are designed solely as auxiliary editing tools for SiYuan, embedding all information directly into formats supported by SiYuan and Markdown. This ensures that all content created by the plugin remains fully visible and functional even after being separated from the plugin — or even from SiYuan itself — such as when exporting to Markdown or sharing on third-party platforms.

For users of the original Pseudocode Widget, this plugin provides a one-click migration feature to help you quickly transition. For detailed steps, please refer to the Usage Guide section below.

Pseudocode Source Code

\begin{algorithm}

\begin{algorithmic}
\PROCEDURE{Quicksort}{$A, p, r$}
    \IF{$p < r$} 
        \STATE $q = $ \CALL{Partition}{$A, p, r$}
        \STATE \CALL{Quicksort}{$A, p, q - 1$}
        \STATE \CALL{Quicksort}{$A, q + 1, r$}
    \ENDIF
\ENDPROCEDURE
\PROCEDURE{Partition}{$A, p, r$}
    \STATE $x = A[r]$
    \STATE $i = p - 1$
    \FOR{$j = p$ \TO $r - 1$}
        \IF{$A[j] < x$}
            \STATE $i = i + 1$
            \STATE exchange
            $A[i]$ with $A[j]$
        \ENDIF
        \STATE exchange $A[i]$ with $A[r]$
    \ENDFOR
\ENDPROCEDURE
\end{algorithmic}
\end{algorithm}

Switch Pseudocode View: Click the menu button in the left side / top-right corner of the code block. If the block is recognized as a valid pseudocode block, an Enable Pseudocode View / Disable Pseudocode View option will appear. Click it to switch between pseudocode view and normal code block.
