You need the familyname of the font, you use the font manager of your OS
to get the name.

\definefontfamily [junction] [rm] [Junction]
\definefontfamily [junction] [mm] [Latin Modern Math]

\definefontfamily [junction-light] [rm] [Junction]
[tf=style:light,bf=style:regular]

I just had it made working this way:

\definefontfamily[mainface]
[ss]
[EgalobhierFarinUrlaubodersonstwasoderwersteht]
[tf=Junction Light, bf=Junction Regular]

\definefontfamily [mainface] [ss] [Junction] [tf=* Light,bf=* Regular]

It seems that as soon as you define your own weights (which you can
mix from different font families) in the fourth pair of brackets,
there can be anything in the third pair of brackets (family name).

\definefontfamily[mainface]
[sans]
[Anything]
[regularfont=Junction Light, boldfont=Junction Regular]

works as well and is more self-explaining.

This will only work when you set a upright font or you will get problems.


What problems do you mean?

When you write nonsense as font name without setting a upright font nothing will show up in your document because the fonts aren’t loaded.

The following seems to work, only that there is a fallback to the fonts defined as upright fonts (which are in fact italic fonts) for the \em parts which seems to be the default behaviour if no italic fonts are defined in the fourth bracket pair:

The \em command uses the slanted and not the italic alternative by default.

When there is no italic or slanted style in the font the regular style is used and when there is no bolditalic or boldslanted style the bold style is used.

Of course these font definitions do not make much sense but they work as I had expected from previous observations. And of course you should define all styles (\rm, \ss, \mm).

You don’t need a serif and a sans font in your document, one of them is enough but math should be always present because some symbols like bullets (but you can force context to take them from the text font) are taken from math.

An advantage of your way

> \definefontfamily [junction-light] [rm] [Junction]
> [tf=style:light,bf=style:regular]

is that you have to type the family name only once if you re-define
weights from the same family.

When you use the keywords for the style you don’t have to look for the
right names and simpelfonts has fallbacks when the requested style isn’t
available.

That is a nice option.


Are there any reasons why one should not use any of all those synonyms?

What do you mean?

I mean that for example inside the second bracket pair “rm” equals “serif”, ”ss“ equals “sans” etc., in the fourth bracket pair “regularfont” equals “tf” etc.

Are there recommendations to not use some of those apart from personal taste? Or is “rm” simply a shorter plain TeX heritage while “serif” is more self-explaining?

It doesn’t matter whether you use rm or serif in the second argument because the argument is checked and converted to a internal name.
