= Quick use of a new font Fonts location on your computer =

Let's take a example, we want The first step is to use [https://declare the storage locations of the fonts.google.com/specimen/Noto+Serif Noto Serif]. The google website enable us you want ConTeXt to download a zip file with the 4 alternative variations (Regular 400, Regular 400 italic, Bold 700, Bold 700 italic)consider.

; #1Either way, ConTeXt will use fonts properly stored in its tree structure (for example, any fonts you would have downloaded from [https://www.fontsquirrel.com Fonts Squirrel] [https://fonts.google.com Google Fonts], or see [[Available Free Fonts]]). Store them is a dedicated folder:* '''TeX users create a "Noto-serif" new folder for each new font in the ConTeXt distribution <code>tex/texmf-fonts/fonts/</code>''', following [http://tug.org/tds/ TeX Directory Structure].:* unzip * it helps the algorithms to deal with the incredibly wide variety of fonts's variables and store the parameters.ttf file in ** People who handle a lot of fonts can be more structured by using*: <code>tex/texmf-fonts/Noto-seriffonts/truetype/vendor/fontfamily</code>.

But it it's very likely that you also want to use the '''fonts already available on your Operating System''':;1. Specify where ConTeXt should looked for 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/.fonts:/usr/share/fonts</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.  In addition, it is no longer necessary to tell ConTeXt where the fonts are located (on Windows or Apple Mac), as a routine has been implemented in <texcode>mtxrun.lua</texcode> that automates the font search. If no value for OSFONTDIR is set, then mtxrun.lua looks to the directory. Here is the code of mtxrun.lua (given here as information) : <texcode>do local osfontdir=osgetenv("OSFONTDIR") if osfontdir and osfontdir~="" then elseif osname=="windows" then ossetenv("OSFONTDIR","c:/windows/fonts//") elseif osname=="macosx" thenossetenv("OSFONTDIR","$HOME/Library/Fonts//; /Library/Fonts//;/System/Library/Fonts//") endend </texcode> On the other hand, if the routine seeks to locate fonts on Windows and Mac, insofar as we are seeking to install new fonts for the Linux system, we must ask ConTeXt — as indicated above — for the path that leads to the directory where the new fonts are deposited; in this case <texcode>tex/texmf-fonts/fonts/</texcode>. Then you'll need to empty the font cache and regenerate it, so that the <texcode>mtxrun --script fonts --list --all --pattern=didot</texcode> command can return something (if you've installed a GFS Didot, or Theano Didot font, for example). To empty the cache and regenerate it, enter the following command (in the directory : /home/johndoe/context/tex/texmf-linux64/bin):<texcode>mtxrun --script cache --erase && mtxrun --generate</texcode> 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, :* and check the situation run <code>mtxrun --script font --list --file -pattern=*noto*</code>:. You should obtain something like<texcode>familyname weight style 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]

= Practical application #2 - Use of the different font variations = * It's not nice to have to write \definedfont[name:yoursuperfont-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]].  

:* Here we use ''mynotoserif''.:* Define the links between ''filenames'' and ''Human People-readable names'' with {{cmd|definefontsynonym}}.:* In this example, the typescript is called "mynotoserif".:* Reminder: you find the filenames for the Noto Serif fonts with <code>mtxrun --script font --list --file -pattern=*noto*</code>: 

; #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 ''Human People-readable names''.

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

; #3. Define the pack of the 4 variations as the roman typeface of the typescript <code>"mynotoserif</code> " :

; #34. You are done! Finally, we have the following input file:
