When I write

        \textbf{return true}\;

The output is like belowenter image description here

However, I don't want end line. If possible, I want like this:

if condition then return true;

Is it possible?


This is entirely covered in the algorithm2e documentation (section 10.4 if-then-else macros), and is provided by \lIf (short for line If):

enter image description here

  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
  \While{not at end of this document}{
    read current\;
      go to next section\;
      current section becomes this one\;
      go back to the beginning of current section\;
    \lIf{condition}{\Return{} \True}
  \caption{How to write algorithms}

  • When I use lIf, the semicolon is automatically inserted at the end of true and there is a space between the word and the semicolon, unlike your snapshot. – padawan Jun 17 '14 at 21:34
  • @cagirici: Why is that? Please provide us with a minimal working example (MWE) that replicates your problem. – Werner Jun 17 '14 at 21:37
  • it was because my mistake. That worked for me. Thank you very much. – padawan Jun 17 '14 at 21:43
  • why line number does not show up? How could I show the line number? – alper Mar 7 '17 at 14:44

    @Avatar: The package option linesnumbered adds line numbers to each algorithm. – Werner Mar 7 '17 at 20:12

For that you should add noend option when declaring the package:
