ShareLatex - Error on import/include a .tex with algorithm2e into another .tex with prosa

Question

I am using ShareLatex. I have an .tex containing some pseudo code using the algorithm2e package. It is as follows:

\documentclass[11pt, a4paper]{article}
\usepackage[portrait, margin=1in]{geometry}
\usepackage{amsmath}
\usepackage[linesnumbered,ruled]{algorithm2e}

\begin{document}
\begin{algorithm}
\SetKwInOut{Input}{Input}
\SetKwInOut{Output}{Output}

\underline{function AlgoTest} $(G)$\;
\Input{bla}
\Output{blubb}
Let $v$ be a vertice $\in V$\;

\ForEach{Vertex $v \in G$}
{
    \tcp{doSth}
}
return $G$\;
\caption{blaBlubb}
\end{algorithm}
\end{document}

It compiles fine and looks like what I want. I now have several of such files containing their own algorithms. I now want to include this code into my work/ prosa text and I want it there to exactly look like the one above. Note that the one above has its own commands like usepackage which is good for doing an error free compile of the single code-file (I mean the above one).

So I am doing like in this tex-file:

\documentclass{article}
\usepackage[subpreambles=true]{standalone}
\usepackage[utf8]{inputenc}
\usepackage{import}

\begin{document}

\import{./}{algotest.tex}

\end{document}

When compiling it also looks fine, no problem but theres an compilation error given by ShareLatex:

/usr/local/texlive/2014/texmf-dist/tex/latex/algorithm2e/algorithm2e.sty, line 1177

Undefined control sequence.

The compiler is having trouble understanding a command you have used. Check that the command is spelled correctly. If the command is part of a package, make sure you have included the package in your preamble using \usepackage{...}. Learn more Was this hint helpful?Yes / No

Hopefully theres a way to solve the compilation error. If there is any information missing, just request for it. Thanks in advance.

Answer 1

I now am using the following workaround (i call it that way because it causes circumstances).

• ever algorithm has its own tex file but without any preamble and without includes etc.
• this way I cannot compile these files directly but need another tex using \input and all neccessary includes to compile this file
  • this is cumbersome because I always need to change the tex for compiling when just changed a little on the pseudo-code

this way my code-tex is looking like this:

\begin{algorithm}
...
\end{algorithm

these "wrapper-tex" is looking like this:

\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{import}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage[linesnumbered,ruled]{algorithm2e}

\begin{document}

\import{Algo}{MyAlgo.tex}

\end{document}

For not getting the line pitch of the surrounding document I use \renewcommand before unsing input on the code and after it again to setting it back. When the code does not fit into the line latex display text, which actually occurs after the input, before the code itself (on the previous page if theres enough space left for text but not for code). I got it by adding a \newpage after the input of the code.

Using include does not show my pseudo code at all. My include that way looks like:

\begin{flushleft}

some text
...
again some text

\renewcommand{\baselinestretch}{1.0}

\input{Algo/MyAlog.tex}

\renewcommand{\baselinestretch}{1.5}


\newpage

againagainsometext
...
u know
\end{flushleft}
...

I had also problems because in the tex with my texts I defined 12pt fontsize while I didn at first on my code-wrapper. The pseudocode that way was enlarged after inputting it. Resizing it using recommendations of these Reduce pseudocode font size (not global) or othere did not help very much, I surrendered after over an hour trying so I reduced my pseudocode by dividing it into multiple/ separate algorithms and by deleting code commentary.
