What is the working directory for relative paths? (Trying to use fontspec)

[ararunaufc]

Hi.

I'm trying to load custom OTF files with fontspec and it keeps complaining about my relative paths.

My _preamble.tex file is next to a folder called res where I'm keeping those font files. The full path from that folder is in the code below, which is how I'm trying to load them:

\newfontfamily\EauDouceSansFont{Eau Douce Sans}[
  UprightFont		= res/fonts/eds/eau_douce_sans_regular.otf,
  BoldFont		= res/fonts/eds/eau_douce_sans_bold.otf,
  ItalicFont		= res/fonts/eds/eau_douce_sans_regular.otf,
  BoldItalicFont	= res/fonts/eds/eau_douce_sans_bold.otf,
]

But I always get this error:

error: _preamble.tex:10: Package fontspec Error: The font
(fontspec)                "res/fonts/eds/eau_douce_sans_regular.otf"
(fontspec)                cannot be found.

For immediate help type H <return>
error: halted on potentially-recoverable error as specified

Can you help me figure out what is wrong...? Thank you, guys.

If you'd like to use relative paths, you can try

\newfontfamily\EauDouceSansFont{eau_douce_sans}[
	Path = ./res/fonts/eds/,  % dont forget the last "/" 
	Extension = .otf,  % can be omitted
	UprightFont = *_regular,  % * maens "eau_douce_sans", full expression is ok
	BoldFont = *_bold,
	ItalicFont = *_italic,
	BoldItalicFont = *_bolditalic,
]

In this configuration, ./ refers to the current directory. It means the path starts from the directory where your LaTeX document (.tex file) is located. ../ is used to go up one level in the directory hierarchy.
