Using the package algorithm2e

[Christophe Bal]

Hello William.

I would like to use the package algorithm2e but the following testing code fails.

-----------------------------------------

%latex

\begin{algorithm}[H]
 \KwData{this text}
 \KwResult{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}

-----------------------------------------

Displaying algorithm is useful when teaching.

Best regards.

Hi, Just type

latex.extra_preamble(r"\usepackage{algorithm2e}")

first, and you're good to go. In general, with %latex, you can do the
above to add all kinds of packages. Type latex.[tab] to see other
similar interesting things you can do, e.g., adding custom macros.

NOTE: I'm going to update SageMathCloud later today with some bugfixes
related to %auto, so that you can type

%auto
latex.extra_preamble(r"\usepackage{algorithm2e}")

in a cell, so that the above pre-amble gets set any time that
worksheet starts. The %auto functionality doesn't isn't 100% at the
moment.

Thanks for this.

I can't remember how to hide a Python code so as to only see the latex output. Can you refresh my memory ?

[Christophe Bal]

I want to talk about the LaTeX code and not the Python one. Maybe a celle using %latex should be automatically hide like it is the case for %md.

Sorry for being an prototypical french who moans often. ;-)

[William A Stein]

Put %hide at the top or just doubleclick on the output.
