Using a package with and without an option in latex

package-optionspackages

I need to use a specific package in two different ways, once with an option and another time without that option. More specifically, I want to use algpseudocode package once with [noend] option and once without it for two algorithms in a document. As far as I read on the web, calling a package twice with different options is not possible. I could not find a clear answer to this problem. Any suggestions would be greatly appreciated.

I found a similar question: algorithm2e – override defaults but it uses algorithm2e package while I am using algorithm.

Edit: The package I need to use with and without [noend] option is algpseudocode not algorithm.

You're probably referring to algpseudocode or algorithmic, rather than algorithm.

Package `algpseudocode`

\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}

\newcommand{\algorithmwithoutend}{%
  \algtext*{EndWhile}%
  \algtext*{EndFor}%
  \algtext*{EndLoop}%
  \algtext*{EndIf}%
  \algtext*{EndProcedure}%
  \algtext*{EndFunction}%
}


\begin{document}

\begin{algorithm}
\algorithmwithoutend

\caption{Euclid’s algorithm without end tags}\label{euclidwithout}

\begin{algorithmic}[1]
\algorithmwithoutend
\Procedure{Euclid}{$a,b$}\Comment{The gcd of $a$ and $b$}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if $r$ is $0$}
      \State $a\gets b$
      \State $b\gets r$
      \State $r\gets a\bmod b$
   \EndWhile\label{euclidendwhilewithout}
   \State \textbf{return} $b$\Comment{The gcd is $b$}
\EndProcedure
\end{algorithmic}

\end{algorithm}

\begin{algorithm}

\caption{Euclid’s algorithm with end tags}\label{euclidwith}

\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}\Comment{The gcd of $a$ and $b$}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if $r$ is $0$}
      \State $a\gets b$
      \State $b\gets r$
      \State $r\gets a\bmod b$
   \EndWhile\label{euclidendwhilewith}
   \State \textbf{return} $b$\Comment{The gcd is $b$}
\EndProcedure
\end{algorithmic}

\end{algorithm}

\end{document}

Package `algorithmic`

\documentclass{article}
\usepackage{algorithm}
\usepackage{algorithmic}

\makeatletter
\newcommand{\algorithmwithoutend}{%
  \renewcommand{\ENDIF}{\end{ALC@if}}%
  \renewcommand{\ENDFOR}{\end{ALC@for}}%
  \renewcommand{\ENDWHILE}{\end{ALC@whl}}%
  \renewcommand{\ENDLOOP}{\end{ALC@loop}}%
}
\makeatother

\begin{document}

\begin{algorithm}

\caption{Example algorithm with end tags}

\begin{algorithmic}
\REQUIRE $n \geq 0$
\ENSURE $y = x^n$
\STATE $y \leftarrow 1$

\IF{$N$ is even}
\STATE $X \leftarrow X \times X$ \STATE $N \leftarrow N / 2$ \ELSE[$N$ is odd]
\STATE $y \leftarrow y \times X$ \STATE $N \leftarrow N - 1$ \ENDIF
\ENDWHILE
\end{algorithmic}

\end{algorithm}

[Tex/LaTex] Using Babel inside the own package produces option-clash error

Here's something you can play with:

\newcommand\affidavit{\germanaffidavit\newpage\englishaffidavit}


\begin{document}
The language is \the\language

This text will be in Language stating the same information as the

Remarks

When switching babel off, compile twice to get rid of the error message.
I'd be inclined to use a custom date command to avoid dependency on other packages for getting it 'right'; what I suggested here is meant to be illustrative of the possibilities, not definitive or even standards-compliant.
Uncomment the \showhyphens command to verify that TeX is hyphenating things correctly (note that the output gets printed in the .log)

[Tex/LaTex] algorithm2e – override defaults

You have to adjust the settings manually:

\documentclass{article}

\usepackage[ruled,vlined,linesnumbered,noresetcount]{algorithm2e}

\makeatletter
\newcommand{\AlgoResetCount}{\renewcommand{\@ResetCounterIfNeeded}{\setcounter{AlgoLine}{0}}}
\newcommand{\AlgoNoResetCount}{\renewcommand{\@ResetCounterIfNeeded}{}}
\newcounter{AlgoSavedLineCount}
\newcommand{\AlgoSaveLineCount}{\setcounter{AlgoSavedLineCount}{\value{AlgoLine}}}
\newcommand{\AlgoRestoreLineCount}{\setcounter{AlgoLine}{\value{AlgoSavedLineCount}}}
\makeatother

\begin{document}

\begin{algorithm}[H]
  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
  initialization\;
  \While{not at end of this document}{
    read current\;
    \eIf{understand}{
      go to next section\;
      current section becomes this one\;
    }{
      go back to the beginning of current section\;
    }
  }
  \caption{How to write algorithms}
\end{algorithm}

\RestyleAlgo{boxed}% Change from the 'ruled' style to 'boxed'
\SetAlgoNoLine% Removes 'vlined' option (somewhat opposite of \SetAlgoVlined)
\LinesNumberedHidden% Removes 'linesnumbered' option (opposite of \LinesNumbered)
\AlgoSaveLineCount% Stores the algorithm line number (similar to 'resetcount' in the package load option)

\begin{algorithm}[H]
  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
  initialization\;
  \While{not at end of this document}{
    read current\;
    \eIf{understand}{

  }
  \caption{How to write algorithms}

\RestyleAlgo{ruled}% Change from the 'boxed' style to 'ruled'
\SetAlgoVlined% Similar to 'vlined' in the package load option
