Is it possible, using XeLaTeX and fontspec.sty, to write a macro, say, \printcurrentfont, such that it would print the name of the font currently in use? I have looked through the fontspec documentation, but so far have not found an answer.

What is the name you want to see? file name? internal font name? family name used by fontspec?– Ulrike FischerApr 10, 2016 at 15:39

Any and all of those, depending on the information that I need to output. I am putting together a number of samples of typefaces and I would like to label them with the name of the current font being sampled.– sgmoyeApr 10, 2016 at 15:45

You can access the internal and the external names of the current font respectively with \the\font and \fontname\font. The former must be stringified in order to print it.
Further massaging of the external font name can be added.
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Libertinus Serif}
\setsansfont{TeX Gyre Adventor}[Scale=MatchUppercase]
\newfontfamily{\junicode}{Junicode}
\DeclareTextFontCommand{\textttup}{\normalfont\ttfamily}
\newcommand{\printinternalcurrentfont}{%
\expandafter\textttup\expandafter{\expandafter\string\the\font}%
}
\newcommand{\printexternalcurrentfont}{%
\expandafter\textttup\expandafter{\fontname\font}%
}
\begin{document}
\printinternalcurrentfont
\printexternalcurrentfont
\bigskip
{\itshape\printinternalcurrentfont\par\printexternalcurrentfont}
\bigskip
\sffamily
\printinternalcurrentfont
\printexternalcurrentfont
\bigskip
\junicode
\printinternalcurrentfont
\printexternalcurrentfont
\end{document}
Output with XeLaTeX
Output with LuaLaTeX
If you're not interested in the finer details, but just in the main font name part, change the definition of \printexternalcurrentfont into
\makeatletter
\newcommand{\printexternalcurrentfont}{%
\expandafter\format@externalcurrentfont\fontname\font:\@nil
}
\def\format@externalcurrentfont#1:#2\@nil{%
\textttup{\@ifnextchar"{\@gobble}{}#1}%
}
\makeatother
The output would become

\fontname\fontreveals the main font name, how does one reveal the mono or sans font name?– MatteoSJun 4, 2018 at 12:53 -

{\sffamily\printinternalcurrentfont\par\printexternalcurrentfont}for the sans font, use\ttfamilyinstead for the mono font.– egregJun 4, 2018 at 12:57 -
I don't get that. The format I'm getting for \printexternalcurrentfont is the TTF font file name in square brackets before the /OT. How would I go about getting just the font name without the square brackets or the .ttf or the /OT or anything else? Jul 16, 2020 at 22:13

@PeterFlynn It depends on how you load the font. In the example I loaded fonts installed system-wide.– egregJul 16, 2020 at 22:22

Same, but it was my fault: I was reading the wrong command (int not ext). Jul 18, 2020 at 22:19
It turns out that the usable answer is much simpler:
\newcommand{\printexternalcurrentfont}{%
\expandafter\getfontname\fontname\font:\@nil}
\def\getfontname"[#1.#2\@nil{#1}
You just need to parse out all the stuff except the actual font name. Unfortunately it does not give you the user-friendly name (eg Raleway Regular) but retains the hyphens. But it's close.
