<p>Dears,</p>
<p>I just want to tell you about a nice setting for working with Metapost!</p>
<p>I use ktikz (<a class="moz-txt-link-freetext" href="https://github.com/fhackenberger/ktikz">https://github.com/fhackenberger/ktikz</a>) a well known editor for pgf/tikz graphics. It exists for linux and windows.</p>
<p>You just have to use the following template for ktikz:</p>
<p>-------------------------</p>
<pre>\documentclass{article}
\usepackage{luamplib}
\usepackage{amsmath,amsfonts,amsthm,amssymb}
\usepackage[usenames,dvipsnames,svgnames]{xcolor}
\usepackage{color}
\usepackage[active,pdftex,tightpage]{preview}
%\PreviewEnvironment[]{tikzpicture}
%\PreviewEnvironment[]{pgfpicture}
\PreviewEnvironment[]{mplibcode}
\begin{document}
\begin{footnotesize}
<>
\end{footnotesize}
\end{document}</pre>
<p>--------------------------</p>
<p>and the actual mp file in the form,</p>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">----------------------
<span style=" font-size:10pt;">\begin{mplibcode}</span></pre>
<pre style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">
</pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">beginfig(1)</span></pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">prologues:=3;</span></pre>
<pre style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">
</pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">u:=1.3cm;</span></pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">pair k[], w[];</span></pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">path p[], c[];</span></pre>
<pre><style type="text/css">p, li { white-space: pre-wrap; }</style></pre>
<pre>.....
</pre>
<pre>.....
</pre>
<pre style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">
</pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">endfig;</span></pre>
<pre style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">
</pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">end;</span></pre>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><span style=" font-size:10pt;">\end{mplibcode}</span></pre>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">---------------------------</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">
</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">and select "lualatex" in the ktikz configuration. This gives you instant display of the graph you are doing, and export to pdf or png or any of the other formats available in ktikz.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">
</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">I think this is a very handy setting, which i didn't see anywhere else, so I thought I share it with you,</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">BR</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; font-size:10pt;">Dimitris
