Note that the tempname function does not create any file or directory at the returned location, so there is nothing to cleanup unless you create a file or directory there. The cleanup option controls whether the process attempts to delete the returned path automatically when the process exits. If a parent directory argument is given, the temporary path will be in that directory instead. When called with no arguments, the temporary name will be an absolute path to a temporary name in the system temporary directory as given by tempdir(). The name is guaranteed to differ from all files already existing at the time of the call to tempname. The path is likely to be unique, but this cannot be guaranteed due to the very remote posibility of two simultaneous calls to tempname generating the same file name. This function only returns a path no file is created. Tempname(parent=tempdir() cleanup=true) -> String
Best practice for creating symlinks on Windows is to create them only after the files/directories they reference are already created. Junction points are slightly more efficient, but do not support relative paths, so if a relative directory symlink is requested (as denoted by isabspath(target) returning false) a symlink will be used, else a junction point will be used.
Note that if the user sets dir_target but target exists and is a file, a directory symlink will still be created, but dereferencing the symlink will fail, just as if the user creates a file symlink (by calling symlink() with dir_target set to false before the directory is created) and tries to dereference it to a directory.Īdditionally, there are two methods of making a link on Windows symbolic links and junction points. If target already exists, by default the type of link will be auto- detected, however if target does not exist, this function defaults to creating a file symlink unless dir_target is set to true. On Windows, symlinks must be explicitly declared as referring to a directory or not. Symlink(target::AbstractString, link::AbstractString dir_target = false)Ĭreates a symbolic link to target with the name link.

A custom error handling function can be provided through onerror keyword argument.
If walkdir or stat encounters a IOError it will rethrow the error by default. The directory tree can be traversed top-down or bottom-up. The iterator returns a tuple containing (rootpath, dirs, files). Return an iterator that walks the directory tree of a directory.
