\subsubsection{Commands with arguments}\label{subsubsec:commands-arguments}
 Let's begin with the simple example in \cref{lst:mycommand}; when \texttt{latexindent.pl}
 operates on this file, the default output is shown in \cref{lst:mycommand-default}.
 \footnote{The command code blocks have quite a few subtleties, described in
 \vref{subsec:commands-string-between}.}

 \begin{cmhtcbraster}[raster column skip=.1\linewidth]
  \cmhlistingsfromfile{demonstrations/mycommand.tex}{\texttt{mycommand.tex}}{lst:mycommand}
  \cmhlistingsfromfile{demonstrations/mycommand-default.tex}{\texttt{mycommand.tex} default output}{lst:mycommand-default}
 \end{cmhtcbraster}

 As in the environment-based case (see \vref{lst:myenv-noAdd1,lst:myenv-noAdd2}) we may
 specify \texttt{noAdditionalIndent} either in `scalar' form, or in `field' form, as shown
 in \cref{lst:mycommand-noAdd1,lst:mycommand-noAdd2}

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd1.yaml}[width=.8\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd1.yaml}}{lst:mycommand-noAdd1}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd2.yaml}[width=.8\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd2.yaml}}{lst:mycommand-noAdd2}
 \end{minipage}

 After running the following commands, \index{switches!-l demonstration}
 \begin{commandshell}
latexindent.pl mycommand.tex -l mycommand-noAdd1.yaml  
latexindent.pl mycommand.tex -l mycommand-noAdd2.yaml  
\end{commandshell}
 we receive the respective output given in
 \cref{lst:mycommand-output-noAdd1,lst:mycommand-output-noAdd2}

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd1.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd1}}{lst:mycommand-output-noAdd1}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd2.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd2}}{lst:mycommand-output-noAdd2}
 \end{minipage}

 Note that in \cref{lst:mycommand-output-noAdd1} that the `body', optional argument
 \emph{and} mandatory argument have \emph{all} received no additional indentation, while
 in \cref{lst:mycommand-output-noAdd2}, only the `body' has not received any additional
 indentation. We define the `body' of a command as any lines following the command name
 that include its optional or mandatory arguments.

 We may further customise \texttt{noAdditionalIndent} for \texttt{mycommand} as we did in
 \vref{lst:myenv-noAdd5,lst:myenv-noAdd6}; explicit examples are given in
 \cref{lst:mycommand-noAdd3,lst:mycommand-noAdd4}.

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd3.yaml}[width=.9\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd3.yaml}}{lst:mycommand-noAdd3}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd4.yaml}[width=.9\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd4.yaml}}{lst:mycommand-noAdd4}
 \end{minipage}

 After running the following commands, \index{switches!-l demonstration}
 \begin{commandshell}
latexindent.pl mycommand.tex -l mycommand-noAdd3.yaml  
latexindent.pl mycommand.tex -l mycommand-noAdd4.yaml  
\end{commandshell}
 we receive the respective output given in
 \cref{lst:mycommand-output-noAdd3,lst:mycommand-output-noAdd4}.

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd3.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd3}}{lst:mycommand-output-noAdd3}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd4.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd4}}{lst:mycommand-output-noAdd4}
 \end{minipage}

 Attentive readers will note that the body of \texttt{mycommand} in both
 \cref{lst:mycommand-output-noAdd3,lst:mycommand-output-noAdd4} has received no additional
 indent, even though \texttt{body} is explicitly set to \texttt{0} in both
 \cref{lst:mycommand-noAdd3,lst:mycommand-noAdd4}. This is because, by default,
 \texttt{noAdditionalIndentGlobal} for \texttt{commands} is set to \texttt{1} by default;
 this can be easily fixed as in
 \cref{lst:mycommand-noAdd5,lst:mycommand-noAdd6}.\label{page:command:noAddGlobal}

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd5.yaml}[width=.9\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd5.yaml}}{lst:mycommand-noAdd5}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile[style=yaml-LST]{demonstrations/mycommand-noAdd6.yaml}[width=.9\linewidth,before=\centering,yaml-TCB]{\texttt{mycommand-noAdd6.yaml}}{lst:mycommand-noAdd6}
 \end{minipage}

 After running the following commands, \index{switches!-l demonstration}
 \begin{commandshell}
latexindent.pl mycommand.tex -l mycommand-noAdd5.yaml  
latexindent.pl mycommand.tex -l mycommand-noAdd6.yaml  
\end{commandshell}
 we receive the respective output given in
 \cref{lst:mycommand-output-noAdd5,lst:mycommand-output-noAdd6}.

 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd5.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd5}}{lst:mycommand-output-noAdd5}
 \end{minipage}
 \hfill
 \begin{minipage}{.45\textwidth}
  \cmhlistingsfromfile{demonstrations/mycommand-noAdd6.tex}{\texttt{mycommand.tex} using \cref{lst:mycommand-noAdd6}}{lst:mycommand-output-noAdd6}
 \end{minipage}

 Both \texttt{indentRules} and \texttt{indentRulesGlobal} can be adjusted as they were for
 \emph{environment} code blocks, as in \vref{lst:myenv-rules3,lst:myenv-rules4} and
 \vref{lst:indentRulesGlobal:environments,lst:opt-args-indent-rules-glob,lst:mand-args-indent-rules-glob}.
