# Fonts location on your computer

The first step is to declare the storage locations of the fonts you want ConTeXt to consider.

Either way, ConTeXt will use fonts properly stored in its tree structure (for example, any fonts you would have downloaded from Fonts Squirrel Google Fonts, or see Available Free Fonts).

• TeX users create a new folder for each new font in tex/texmf-fonts/fonts/, following TeX Directory Structure.
• it helps the algorithms to deal with the incredibly wide variety of fonts's variables and parameters.
• People who handle a lot of fonts can be more structured by using
tex/texmf-fonts/fonts/truetype/vendor/fontfamily.

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: set OSFONTDIR=c:/windows/fonts/
• MAC: export OSFONTDIR=/Library/Fonts/:/System/Library/Fonts:$HOME/Library/Fonts • GNU/LINUX: export OSFONTDIR=$HOME/.fonts:/usr/share/fonts
• Add it to your .bashrc or shell equivalent to make the declaration permanent.
2. Run ConTeXt to index the files and the fonts
mtxrun --generate

3. Check by looking for the specific font you want to use next. A common example
mtxrun --script fonts --list --all --pattern='*helvetica*'

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 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 indexed by ConTeXt.
• for example, create a "Noto-serif" in the ConTeXt distribution tex/texmf-fonts/fonts/.
• unzip and store the .ttf file in tex/texmf-fonts/fonts/Noto-serif/.
• Regenerate ConTeXt databases
• the file database: mtxrun --generate
• the fonts database: mtxrun --script font --reload
#2. Now you can check the fontname used to identify the fonts,
• run mtxrun --script font --list --file -pattern=*noto*. You should obtain something like
familyname  weight  style   width   variant  fontname             filename  subfont  fontweight

notoserif   bold    normal  normal  normal   notoserifbold        NotoSerif-Bold.ttf
notoserif   bold    italic  normal  normal   notoserifbolditalic  NotoSerif-BoldItalic.ttf
notoserif   normal  italic  normal  normal   notoserifitalic      NotoSerif-Italic.ttf
notoserif   normal  normal  normal  normal   notoserif            NotoSerif-Regular.ttf

#3. You are done! You can use the font anywhere in your input files with \definedfont
• it's good to add *default to benefit from default features, like for example kerning.
\definedfont[name:notoserifbolditalic*default at 12 pt]
The quick brown fox jumps over the lazy dog


# Practical application #2 - Use 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 \tf, \it, \bf, \bi (see Font styles and alternatives), and all the typesetting of your document will use a consistent set of fonts.
• Many typescripts are ready for use on usual free and commercial fonts, and obviously for the ConTeXt distribution's Fonts.

#1. Define a new typescript in your input file, with \starttypescript.
• In this example, the typescript is called "mynotoserif".
• Reminder: you find the filenames for the Noto Serif fonts with mtxrun --script font --list --file -pattern=*noto*:
\starttypescript [mynotoserif]
% \definefontsynonym[Human readable]       [file:filename without extension]
\definefontsynonym[NotoSerif-Regular]    [file:NotoSerif-Regular]
\definefontsynonym[NotoSerif-Italic]     [file:NotoSerif-Italic]
\definefontsynonym[NotoSerif-Bold]       [file:NotoSerif-Bold]
\definefontsynonym[NotoSerif-BoldItalic] [file:NotoSerif-BoldItalic]
\stoptypescript

#2. The boring step, define the links between ConTeXt basics names and the People-readable names.
• It's good to add a fallback.
\starttypescript [mynotoserif]
% \definefontsynonym[ConTeXt basics name] [Human readable]       [features=default]
\definefontsynonym[Serif]                [NotoSerif-Regular]    [features=default]
\definefontsynonym[SerifItalic]          [NotoSerif-Italic]     [features=default]
\definefontsynonym[SerifBold]            [NotoSerif-Bold]       [features=default]
\definefontsynonym[SerifBoldItalic]      [NotoSerif-BoldItalic] [features=default]
\stoptypescript

#3. Define the pack of the 4 variations as the roman typeface of the typescript "mynotoserif"
\starttypescript [mynotoserif]
\definetypeface [mynotoserif]    [rm] [serif] [mynotoserif]    [default]
\stoptypescript

#4. You are done! Finally, we have the following input file
\starttypescript [mynotoserif]
\definefontsynonym[NotoSerif-Regular]    [file:NotoSerif-Regular]
\definefontsynonym[NotoSerif-Italic]     [file:NotoSerif-Italic]
\definefontsynonym[NotoSerif-Bold]       [file:NotoSerif-Bold]
\definefontsynonym[NotoSerif-BoldItalic] [file:NotoSerif-BoldItalic]
\stoptypescript

\starttypescript [mynotoserif]
\setups[font:fallback:serif]
\definefontsynonym[Serif]                [NotoSerif-Regular]    [features=default]
\definefontsynonym[SerifItalic]          [NotoSerif-Italic]     [features=default]
\definefontsynonym[SerifBold]            [NotoSerif-Bold]       [features=default]
\definefontsynonym[SerifBoldItalic]      [NotoSerif-BoldItalic] [features=default]
\stoptypescript

\starttypescript [mynotoserif]
\definetypeface [mynotoserif]    [rm] [serif] [mynotoserif]    [default]
\stoptypescript

\setupbodyfont[mynotoserif]
\setupbodyfont[12pt]
{    The quick brown fox jumps over the lazy dog}\\
{\it The quick brown fox jumps over the lazy dog}\\
{\bf The quick brown fox jumps over the lazy dog}\\
{\bi The quick brown fox jumps over the lazy dog}\\


And it gives:

# Install your new typescript 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, we remind the definition:

\starttypescript [mynotoserif]
\definefontsynonym[NotoSerif-Regular]    [file:NotoSerif-Regular]
\definefontsynonym[NotoSerif-Italic]     [file:NotoSerif-Italic]
\definefontsynonym[NotoSerif-Bold]       [file:NotoSerif-Bold]
\definefontsynonym[NotoSerif-BoldItalic] [file:NotoSerif-BoldItalic]
\stoptypescript

\starttypescript [mynotoserif]
\setups[font:fallback:serif]
\definefontsynonym[Serif]                [NotoSerif-Regular]    [features=default]
\definefontsynonym[SerifItalic]          [NotoSerif-Italic]     [features=default]
\definefontsynonym[SerifBold]            [NotoSerif-Bold]       [features=default]
\definefontsynonym[SerifBoldItalic]      [NotoSerif-BoldItalic] [features=default]
\stoptypescript

\starttypescript [mynotoserif]
\definetypeface [mynotoserif]    [rm] [serif] [mynotoserif]    [default]
\stoptypescript


1. Save your file as type-(some-name-you-like).tex, for example here type-mynotoserif.tex
2. Copy the typescript files into tex/texmf-fonts/tex/context/user/
3. Run context --generate to update ConTeXt file database
4. It's done! Now, two lines at the beginning of any input will declare to typeset with the new fonts:
\usetypescriptfile[mynotoserif] % this is the 'some-name-you-like' part of the saved filename
\setupbodyfont[mynotoserif] % this is the first argument to \definetypeface


#### Note:

The naming convention for typescript files has changed in LMTX

There has been a change in the naming of typescript file, a simple "type-" prefix isn't anough anymore, you have to change it to "type-imp-" (e.g. type-imp-sourceserif.tex) to be found by ConTeXt.

Valid file extensions for a typescript file in LMTX (and MkIV) are "tex", "mkiv" and "mkxl".
