\title{manage font working directory}
\usage{
fonts_cache_dir()
rm_fonts_cache()
init_fonts_cache()
}
\description{
Initialize or remove font directory used
to store downloaded font files.
This directory is managed by R function \code{\link[=R_user_dir]{R_user_dir()}} but can also
be defined in a non-user location by setting ENV variable \code{GDTOOLS_CACHE_DIR}
or by setting R option \code{GDTOOLS_CACHE_DIR}.
Its value can be read with the \code{fonts_cache_dir()} function.
The directory can be deleted with \code{rm_fonts_cache()} and
created with \code{init_fonts_cache()}.
}
\examples{
fonts_cache_dir()
options(GDTOOLS_CACHE_DIR = tempdir())
fonts_cache_dir()
options(GDTOOLS_CACHE_DIR = NULL)
Sys.setenv(GDTOOLS_CACHE_DIR = tempdir())
fonts_cache_dir()
Sys.setenv(GDTOOLS_CACHE_DIR = "")
init_fonts_cache()
dir.exists(fonts_cache_dir())
rm_fonts_cache()
dir.exists(fonts_cache_dir())
}
