ConTeXT provides a tight integration of TeX and [[Metapost]].
fix pragma links & typos
MetaFun is ConTeXt’s extension of the [[MetaPost]] language. It provides a tight integration of both TeX and [[MetaPost]]. MetaPost can used behind the scenes for some graphic trickery. This integration is also helpful for drawing figures in MetaPost and use them in a document.
'''The [[manual:metafun-p.pdf|MetaFun manual]]''', also available in a [[manual:metafun-s.pdf|screen version]].

This page is a brief overview of some of the commonly used commands.

[[File:ConTeXt-System.png|700px]]
= Commonly used commands =
; {{cmd|defineMPinstance}}, {{cmd|setupMPinstance}}: used to set up MetaPost invocations with particular features. One use case could be to select a sans serif font for all MetaPost labels.
: {{cmd|startMPenvironment}} '''is DEPRECATED''' in which one could place settings that one only wanted to apply in the MetaPost environment, but not in the document itself. One should use {{cmd|defineMPinstance}} and {{cmd|setupMPinstance}}, instead.
; {{cmd|startMPinclusions}}: Inside, one can specify MetaPost files to ''input'', and also define MetaPost functions.
; {{cmd|startuseMPgraphic}}, {{cmd|useMPgraphic}}: defines a piece of graphics code that is processed anew every time the graphic is placed with {{cmd|useMPgraphic}}.
; {{cmd|startreusableMPgraphic}}, {{cmd|reuseMPgraphic}}: For graphics that are the same every time, it is better to use {{cmd|startreusableMPgraphic}}: the graphic is compiled only once, and the one resulting picture can be placed at various points with {{cmd|reuseMPgraphic}}.
; {{cmd|startMPcode}}: When reusing a graphic is not important, you can simply use {{cmd|startMPcode}}.
; {{cmd|startMPpage}}: produces a page a containing MetaPost graphic. The page is just large enough to contain the graphic. The resulting pdf is self-contained (it has all the fonts embedded). This is useful if you want to send the figure to a coauthor or a journal.
; {{cmd|startstaticMPfigure}}, {{cmd|usestaticMPfigure}}: The {{cmd|startuseMPgraphic}} series of commands were designed for using MetaPost for drawing fancy frames and backgrounds and not for using <i>stand-alone</i> graphics for a document. {{cmd|startstaticMPfigure}} creates a separate pdf file containing the graphic. This pdf can be included in the document using {{cmd|usestaticMPfigure}}. ConTeXt is clever enough to recompile the resulting MetaPost file only if something inside the {{cmd|startstaticMPfigure}} has changed.
