Elixir:
Checking if a directory exists
How to:
Elixir’s standard library offers a straightforward way to check for the existence of a directory through the File
module. Here’s how you can use it:
if File.dir?("path/to/directory") do
IO.puts "Directory exists!"
else
IO.puts "Directory does not exist."
end
Sample output, assuming the directory does not exist:
Directory does not exist.
For more advanced filesystem interactions, including checking directory existence, you might consider using third-party libraries like FileSystem
. While Elixir’s standard capabilities are sufficient for many cases, FileSystem
can offer more nuanced control and feedback for complex applications. However, for the basic need of checking if a directory exists, sticking to the native File
module is typically recommended since it’s readily available and doesn’t require any external dependencies.
