Value

A list of information about the package

Examples

if (FALSE) { # \dontrun{
# This only works inside a 'fusen' built package
pkg_structure <- get_package_structure()
draw_package_structure(pkg_structure)
} # }

# Example with a dummy package
dummypackage <- tempfile("drawpkg.structure")
dir.create(dummypackage)

# {fusen} steps
fill_description(pkg = dummypackage, fields = list(Title = "Dummy Package"))

  add_flat_template(pkg = dummypackage, overwrite = TRUE, open = FALSE)
)

  # to list in "keep"
  dir.create("R")

  # Works with classical package
  pkg_structure <- get_package_structure()
