Interfaces package: quickprofile on changefont

Question

I'm sorry but I do not understand much English, so I do not understand how to use the command \quickprofile in the 'interfaces' package.

\documentclass[a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{interfaces}
\usepackage{lipsum}

\begin{document}

{\changefont{shape=it}
  \lipsum[1]
}

{\changefont{size+ = 1}
  \lipsum[1]
}

{\quickprofile2{shape=bf}
  \lipsum[1]
}

\end{document}

Could someone show me an example please?

Answer 1

The \quickprofile command simply reports in the console output and the log file the result of doing n repetitions of the code of its argument.

e.g.

\documentclass{article}
\usepackage{interfaces}
\begin{document}
\def\foo{This is some text.}
\quickprofile1000{\foo}
\end{document}

The output of the console of this run is:

Profiler: step 0
Profiler: step 1

... 

Profiler: step 998 
Profiler: step 999

(interfaces) quickprofile: Time elapsed for 1000 cycles: 0sec 13ms

This expands \foo 1000 times and reports the amount of time elapsed. I think it is only of practical use to developers who are concerned about the speed of complex code. For end users it is likely to have little value.
