## This module implements symlink (symbolic link) handling.
## .. importdoc:: os.nim
from std/paths import Path, ReadDirEffect
from std/private/ossymlinks import symlinkExists, createSymlink, expandSymlink
proc symlinkExists*(link: Path): bool {.inline, tags: [ReadDirEffect], sideEffect.} =
## Returns true if the symlink `link` exists. Will return true
## regardless of whether the link points to a directory or file.
result = symlinkExists(link.string)
proc createSymlink*(src, dest: Path) {.inline.} =
## Create a symbolic link at `dest` which points to the item specified
## by `src`. On most operating systems, will fail if a link already exists.
##
## .. warning:: Some OS's (such as Microsoft Windows) restrict the creation
## of symlinks to root users (administrators) or users with developer mode enabled.

createSymlink(src.string, dest.string)
proc expandSymlink*(symlinkPath: Path): Path {.inline.} =
## Returns a string representing the path to which the symbolic link points.
##
## On Windows this is a noop, `symlinkPath` is simply returned.
