= Getting access Using [[LuaTeX]] as the processing engine in ConTeXt allows one to directly use fonts installed on the user's system . Instead of converting all fonts =into the standard <code>.tfm</code> and <code>.vf</code> formats (as outlined in some [[My Way]] documents<ref>[http://dl.contextgarden.net/websitesarchive/atl/tex/OpenType.pdf OpenType in ConTeXt] by Adam Lindsay</ref><ref>[http://dl.contextgarden.net/myway/expertfonts.pdf Installing Expert Fonts: Minion Pro] by Idris Samawi Hamid</ref>), LuaTeX creates these metric files automatically at run-time. This greatly simplifies font installation in ConTeXt.

= How LuaTeX can use non-TeX handles system fonts (in OpenType, TrueType or Type1 format) directly.=

The first time LuaTeX can use fonts in non-TeX format (e.g. OpenType, TrueType or Type1 format) directly. When ConTeXt processes a file that you runuses such non-traditional fonts, the actual fonts themselves are loaded in LuaTeX's embedded section of fontforge to extract their metric information. This removes the need for tfm and vf files on your disk, but it is also a somewhat lengthy and often memory-hungry process. Fortunately, the result of that internal preprocessing are also saved inside the texmf cache. Future runs using the same font (not just this file, but all files using that particular font) can then use the cached version of the metrics instead.

context myfile.tex on a file Mac OS users should note that uses such non-traditional fonts the current version of LuaTeX (which is probably always0.60), has severe problems dealing with the actual new TrueType collection fonts themselves have to be loaded in luatex's embedded section of fontforge to extract their metric informationSnow Leopard (Mac OS 10. This removes the need for tfm and vf files on your disk, but it is also a somewhat lengthy and often memory-hungry process6). That is why the results of that internal preprocessing are also saved inside the texmf cacheThe older Mac OS . Future runs using the same font (not just this file, but all files using that particular font) can then use the cached version of the metrics insteaddfont format works fine nowadays.

You need to specify where the fonts should be looked for, by setting the <code>OSFONTDIR</code> environment variable. For instanceOn Windows,this might be achieved by running

if the fonts should be found in <code>c:/windows/fonts/</code>; or. For Unix machines,

if indicate that the fonts should be found in both <code>/usr/local/share/fonts</code> and <code>$HOME/.fonts</code>. The font database will then be automatically generated in the next run of <code>context</code>

The font database will then be automatically generated in the next run of <code>context</code>. You can also generate it manually by typing mtxrun --script font --reloador equally

mtxrun --script fonts --list--all --pattern=*

mtxrun --script fonts --list --all --pattern=Delicious*

Handling fonts in LuaTeX can be done* in a simple but limited way, using the <code>simplefonts<[http://pragma-ade.com/code> module;* in the standard way, using [[TypeScripts]general/manuals/mfonts.pdf Old Fonts Manual by Hans Hagen]

It simplifies the use of = Using fonts in LuaTeX by* freeing the user from writing or using [[TypeScripts]];* offering an interface similar to the [http://www.ctan.org/tex-archive/macros/xetex/latex/fontspec/ fontspec package for XeTeX]=

For instanceHandling fonts in LuaTeX can be done* in a simple but limited way, assuming using the [http://www.josbuivenga.demon.nl/delicious.html Delicious fonts] are properly installed and recognized by ConTeXt, you can simply write: [simplefonts|<texcodecode>\usemodule[simplefonts</code> module] % load ];* in the module\setmainfontstandard way, using [[DeliciousTypeScripts]] % set Delicious as main (serif) font \starttext\rm\tf roman \it italic \bf bold \bi bolditalic \sc smallcaps\stoptext</texcode>
