I am trying to split a long line in my algorithm, which is in my if condition into two lines, while maintaining indentation. AND I don't want the line break to be anywhere but after my -or- in the code.

SO here is my code

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}

\usepackage{algorithm}
\usepackage{algpseudocode}

\algnewcommand\algorithmicor{\textbf{or}}
\newcommand{\pushcode}[1][1]{\hskip\dimexpr#1\algorithmicindent\relax}

\begin{algorithm}[h]
\caption{Core genome identification}
\begin{algorithmic}[1]
%I tired using this push
\While{$list$ is not empty \algorithmicor \\ \pushcode[1] second condition} 
\EndWhile
\end{algorithmic}
\end{algorithm}

\end{document}

I have tried it with this push for example, but this gives me a new line number what I don't want!

And other suggestions like defining

 \newcommand{\myindent}[1]{
 \newline\makebox[#1]{}
 }

Also puts the indent on a spec. indentation, what is not what I am searching for. I want it to be at the same indentation as the condition before. So something like

if (this is my first condition OR
    this is the second)
2

Redefine the loop and if statements in the preamble (after \usepackage{algpseudocode}) as follows:

\newcommand\CONDITION[2]%
  {\begin{tabular}[t]{@{}l@{}l@{}}
     #1&#2
   \end{tabular}%
  }
\algdef{SE}[WHILE]{While}{EndWhile}[1]%
  {\algorithmicwhile\ \CONDITION{#1}{\ \algorithmicdo}}%
  {\algorithmicend\ \algorithmicwhile}
\algdef{SE}[FOR]{For}{EndFor}[1]%
  {\algorithmicfor\ \CONDITION{#1}{\ \algorithmicdo}}%
  {\algorithmicend\ \algorithmicfor}
\algdef{S}[FOR]{ForAll}[1]%
  {\algorithmicforall\ \CONDITION{#1}{\ \algorithmicdo}}
\algdef{SE}[REPEAT]{Repeat}{Until}{\algorithmicrepeat}[1]%
  {\algorithmicuntil\ \CONDITION{#1}{}}
\algdef{SE}[IF]{If}{EndIf}[1]%
  {\algorithmicif\ \CONDITION{#1}{\ \algorithmicthen}}%
  {\algorithmicend\ \algorithmicif}%
\algdef{C}[IF]{IF}{ElsIf}[1]%
  {\algorithmicelse\ \algorithmicif\ \CONDITION{#1}{\ \algorithmicthen}}

The definitions are taken from the style file algpseudocode.sty and modified to handle multiline conditions.

Here is a complete example:

\documentclass{article}
\usepackage{algpseudocode}

... Code from above ...

\begin{document}
\begin{algorithmic}[1]
  \While{short condition} 
  \EndWhile
  \While{very long condition\\broken into two lines} 
  \EndWhile
\end{algorithmic}
\end{document}
