I am using
\usepackage[norelsize, linesnumbered, ruled, lined, boxed, commentsnumbered]{algorithm2e}
\RestyleAlgo{boxruled}
It seems that algorithm2e has the default repeat-until construct.
But I want to use do-while construct as do something while(u is not v).
The repeat-until construct is different from the do-while construct.
My search resulted in do-while loop in pseudo code. But the answer is for algorithmicx.
How this can be done in `algorithm2e?
You can create a do-while construct using the same technique that a repeat-until construct is generated. They both fall under what algorithm2e calls "Repeat macros":
\SetKwRepeat{Do}{do}{while}
The above now allows you to use
\Do{<end condition>}{<stuff>}
Here is a minimal example showing its use/output:
\documentclass{article}
\usepackage[linesnumbered, ruled]{algorithm2e}
\SetKwRepeat{Do}{do}{while}%
\begin{document}
\begin{algorithm}[H]
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e }
