Using handwriting font in proofs

Question

I read several posts but still could not figure out how to do the following. I want to use handwriting font, say, Augie font, within proof environment. I installed the package emerald. Then I read someone suggested to define a new environment like

\newenvironment{myfont}{\fontfamily{<familyname>}\selectfont}{\par}

I could not make it work since I could not find its font family in the first place. Could any one provide me with a concrete example, please? Thank you! Here is the codes I have at the moment.

\documentclass[english]{scrartcl}

\usepackage{bm}
\usepackage{graphics}
\usepackage{relsize}
\usepackage{color}
\usepackage{bigints}
\usepackage{graphicx}
\DeclareGraphicsExtensions{.eps, .pdf, .jpeg, .png}
\usepackage{epstopdf}
\usepackage{float}
\usepackage{hyperref}
\usepackage{environ}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{amsmath}
\setkomafont{disposition}{\normalfont}
\usepackage{graphicx}

\usepackage{emerald}

\usepackage{geometry}
 \geometry{
 a4paper,
 left=20mm,
 right=20mm,
 top=10mm,
 bottom=10mm
 }

\usepackage{listings}
\usepackage{color}
\setcounter{tocdepth}{1}
\usepackage{tocloft}
\definecolor{blue}{rgb}{0,0,1}
\definecolor{red}{rgb}{1,0,0}

\newenvironment{myfont}{\fontfamily{<familyname>}\selectfont}{\par}

\renewcommand{\cftsecleader}{\cftdotfill{\cftdotsep}}
\newcommand*\ruleline[1]{\par\noindent\raisebox{.8ex}{\makebox[\linewidth]{\hrulefill\hspace{1ex}\raisebox{-.8ex}{#1}\hspace{1ex}\hrulefill}}}

\begin{document}

\section{Question One}

\begin{proof}
\begin{myfont}
  Some text in the new font.
\end{myfont}
\end{proof}

\end{document}

Answer 1

You have these options:

Use \newenvironment{myfont}{\fontfamily{augie}\selectfont}{\par}

Then it boils down to

\begin{proof}
\begin{myfont}
  Some text in the new font.
\end{myfont}
\end{proof}

Or use the switch \ECFAugie

\begin{proof}
\ECFAugie
  Some text in the new font.
\end{proof}

You may use etoolbox and its macro \AtBeginEnvironment to hook in to the proof environment so that some typing is saved. That is a different story.

Bonus: Some hand written fonts.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{frcursive}
\usepackage{calligra}
\usepackage{emerald}% 1
\usepackage{aurical}% 2
\usepackage{pbsi}% 3

%\usepackage{chancery}%Zapf chancery font

\usepackage{la}
\newcommand{\setfont}[2]{{\fontfamily{#1}\selectfont #2}}
\begin{document}
\noindent\setfont{frc}{\Huge This is french cursive font.}\\[5pt]
\setfont{calligra}{\Huge This is Calligra font.}\\[5pt]
\setfont{pzc}{\Huge This is chancery font.}\\[5pt]
 %{\Huge\itshape This is chancery italic font.}\\[5pt]
\section{Augie} {\ECFAugie This is Augie font --1.}\\[5pt]
\section{Auriocus Kalligraphicus} {\Fontauri This is Auriocus Kalligraphicus font --2.}\\[5pt]
\section{BrushScriptX-Italic} {\bsifamily This is BrushScriptX-Italic font --3.}\\[5pt]

This is for Nasser. As Jim Hefferon and LaRiFaRi said i comments, you can download a free font (from here, and here, say) and use xelatex or lualatex to get what you want.

\documentclass{article}
\usepackage[no-math]{fontspec}

\setmainfont[
  Ligatures=TeX,  
]{Stylus ITC TT}

\begin{document}
  This is some TEXT.
\end{document}
