Tag: read file

In Elixir, you can use the File.read/1 function to read the contents of a file into a string. Here is an example of how to use this function:

# Open the file and read its contents into a string
{:ok, contents} = File.read("path/to/file.txt")

# Print the contents of the file
IO.puts(contents)

If the file does not exist or there is an error reading the file, File.read/1 will return an error tuple {:error, reason}. You can handle this case by using a case statement or by using the try/catch macro:

# Try reading the file, and handle any errors that may occur
case File.read("path/to/file.txt") do
  {:ok, contents} ->
    IO.puts(contents)
  {:error, reason} ->
    IO.puts("Error reading file: #{reason}")
end

# Alternatively, you can use the `try/catch` macro
try do
  {:ok, contents} = File.read("path/to/file.txt")
  IO.puts(contents)
catch
  {:error, reason} ->
    IO.puts("Error reading file: #{reason}")
end

I hope this helps! Let me know if you have any questions or need further assistance.
