expanduser
expanduser(path::AbstractString) -> AbstractString
On Unix systems, replace a tilde character at the start of a path with the current user's home directory.
Examples
-
Expand tilde in a file path:
julia> expanduser("~/Documents/file.txt") "/home/username/Documents/file.txt"This example expands the tilde character
~at the beginning of the file path with the current user's home directory path. -
Expand tilde in a directory path:
julia> expanduser("~/Downloads") "/home/username/Downloads"It expands the tilde character
~at the start of the directory path to the user's home directory. - Handle paths without tilde:
julia> expanduser("/var/www/html/index.html") "/var/www/html/index.html"If the path does not contain a tilde character, the
expanduserfunction returns the path as-is.
Common mistake example:
julia> expanduser("~username/Documents/file.txt")
ERROR: ArgumentError: invalid path: path must start with '~'In this example, the path provided starts with ~username, which is not a valid usage of expanduser. The tilde character is expected to be at the start of the path, followed by a slash or the end of the string. Make sure to only use ~ at the start of the path to expand the user's home directory.
