Changes

But it it's very likely that you also want to use the '''fonts already available on your Operating System''':;1. Specify where the fonts ConTeXt should be looked for:* This is done fonts, by setting the '''OSFONTDIR''' environment variable.:** WINDOWS: <code>set OSFONTDIR=c:/windows/fonts/</code>:** MAC: <code>export OSFONTDIR=/Library/Fonts/;:/System/Library/Fonts;:$HOME/Library/Fonts</code>:** GNU/LINUX: <code>export OSFONTDIR=$HOME/Library.fonts:/Fontsusr/;share/System/Library/Fonts;$HOME/Library/Fontsfonts</code>:** Add it to your .bashrc or shell equivalent to make the declaration permanent.;2. Run ConTeXt to index the files and the fonts :<texcode>mtxrun --generatemtxrun --script fonts --reload</texcode>;3. Check by looking for the specific font you want to use next. A common example:<texcode>mtxrun --script fonts --list --all --pattern='*helvetica*'</texcode> '''NOTE''' : In recent versions of ConTeXt (2023), the use of wildcards is no longer necessary to check for the presence of a particular font.

;2. Update In addition, it is no longer necessary to tell ConTeXt databases:* where the file database: fonts are located (on Windows or Apple Mac), as a routine has been implemented in <codetexcode>mtxrun --generate.lua</codetexcode>:* that automates the font search. If no value for OSFONTDIR is set, then mtxrun.lua looks to the directory. Here is the fonts database: <code>of mtxrun --script font --reload</code>.lua (given here as information) :

;3. Check by looking for the specific font you want to use next<texcode>do local osfontdir=osgetenv("OSFONTDIR") if osfontdir and osfontdir~="" then elseif osname=="windows" then ossetenv("OSFONTDIR","c:* a very common example /windows/fonts//") <code>mtxrun --script font --list --file -patternelseif osname==*helvetica*"macosx" thenossetenv("OSFONTDIR","$HOME/Library/Fonts//;/Library/Fonts//;/System/Library/Fonts//") endend </codetexcode>

You have now:* to define [[Use_fonts_found_on_the_web#Use_of_the_different_font_variations|a new typescript]] or use one of To empty the [[Typescripts_examples| many typescripts already available]]* cache and then [[Use_fonts_found_on_the_web#Install_and_use_your_new_typescript_definition| install and use regenerate it]] , enter the following command (in you input file.the directory : /home/johndoe/context/tex/texmf-linux64/bin):<texcode>mtxrun --script cache --erase && mtxrun --generate</texcode>

= Quick use of a new Now you can search for the font =you've just installed.

  Now, let's learn how to use them for typesetting. = Practical application #1 - Quick use of a new font = Let's take an example: we want to use [https://fonts.google.com/specimen/Noto+Serif Noto Serif].  If it is already installed on your computer, and you already updated the ConTeXt databases like shown previously, go directly to '''#2'''. It not, you have to download and store it first. The Google website provides a zip file with the 4 alternative variations (Regular 400, Regular 400 italic, Bold 700, Bold 700 italic). ; #1. Store them in a dedicated folder [[#Fonts location on your computer|indexed by ConTeXt]].:* for example, create a "Noto-serif" in the ConTeXt distribution <code>tex/texmf-fonts/fonts/</code>.:* unzip and store the .ttf file in <code>tex/texmf-fonts/fonts/Noto-serif/</code>.:* Regenerate ConTeXt databases:** the file database: <code>mtxrun --generate</code>:** the fonts database: <code>mtxrun --script font --reload</code> ; #2. Now you can check the ''fontname'' used to identify the fonts, :*run <code>mtxrun --script font --list --file -pattern=*noto*</code>. You should obtain something like<texcode>familyname weight style width variant fontname filename subfont fontweight notoserif bold bold normal normal normal normal notoserifbold NotoSerif-Bold.ttfnotoserif bold bold italic normal normal normal notoserifbolditalic NotoSerif-BoldItalic.ttfnotoserif normal italic normal normal normal notoserifitalic NotoSerif-Italic.ttfnotoserif normal normal normal normal normal notoserif NotoSerif-Regular.ttf

; #3. Your You are done! You can use the font anywhere in your input files with {{cmd|definedfont}}:* it's good to add <code>*default</code> to benefit from default features, like for example [http://www.pragma-ade.nl/general/manuals/fonts-mkiv.pdf#&#91;169,{%22name%22:%22Fit%22}&#93; kerning].

\definedfont[filename:NotoSerif-BoldItalic notoserifbolditalic*default at 12pt12 pt]

 = Use of the different font variations = * It's not nice to have to write \definedfont[filename:YourSuperFontyoursuperfont-WeightStyle weightstyle*default at xxpt] each time you want to use a particular font. * That why it's worth defining a '''typescript'''. It's just 3 steps, and less than 5 minutes. Then, you will be able to easily switch between fonts with {{cmd|tf}}, {{cmd|it}}, {{cmd|bf}}, {{cmd|bi}} (see [[Font_Switching#Font_styles_and_alternatives|Font styles and alternatives]]), and all the typesetting of your document will use a consistent set of fonts.* [[Typescripts_examples| Many typescripts are ready ]] for use on usual free and commercial fonts, and obviously for the [[ConTeXt_distribution's_Fonts|ConTeXt distribution's Fonts]].

; #2. The boring step, define the links between ''[https://github.com/contextgarden/context-mirror/blob/a0270f13065d116355a953c6f246cbba26289fc2/tex/context/base/mkiv/font-sel.lua#L514 ConTeXt basics names]'' and the ''People-readable names''.

\setups[font:fallback:serif] % security: if not found==> bask back to defaults% \definefontsynonym[ConTeXt bascics basics name] [Human readable] [features=default]

= Install and use your new typescript definition to use it anywhere =

You will probably want to use your new customized typescript definition across different documents, so you have to install them in the distribution. Here is , we remind the definition.:

# Save your file as <code>type-(fontname|foundrysome-name-you-like).tex</code>, for example here <code>type-mynotoserif.tex</code>

# You are It's done!Now, two lines at the beginning of any input will declare to typeset with the new fonts:<texcode>#* you can add \usetypescriptfile[mynotoserif] at % this is the beginning 'some-name-you-like' part of any input filethe saved filename#* and \setupbodyfont[mynotoserif] will declare % this is the first argument to \definetypeface</texcode> ====Note:==== The naming convention for typescript files has changed in LMTX <blockquote> There has been a change in the naming of typescript file, a simple <code>"type-"</code> prefix isn't anough anymore, you have to change it to <code>"type-imp-" </code>(e.g. type-imp-sourceserif.tex) to typeset with your new fontbe found by ConTeXt. Valid file extensions for a typescript file in LMTX (and MkIV) are "tex", "mkiv" and "mkxl". Wolfgang [20 Dec 2020]</blockquote>  [[Category:Fonts]]
