How can I replace (") by (')
Hello, I have a small problem.
if i have something like:
path = '/home/trini/phoenix-vosk/deps/vosk/priv/vosk-model-small-en-0.42'
model = :vosk.model_new(path)
everything works correctly for me
The problem occurred when I wanted to replace the path with an environment variable and i did something like that:
env = System.get_env("VOSK_MODEL")
model = :vosk.model_new(env)
and it happens that vosk requires that the path be inside single quotes (') but System.get_env("VOSK_MODEL") returns the path in double quotes (")
I’ve tried replacing the double quotes with singles as follows, but to no avail.
cleaned_model_path = String.replace(env, "\"", "'")
clarified that if we do something like
env = System.get_env('VOSK_MODEL')
the function System.get_env gives an error
The question I have is how can I replace (") by (')

the problem solved I’m left something like this:
env = System.get_env("VOSK_MODEL")
c_path = String.to_charlist(env)
model = :vosk.model_new(c_path)

Strings (written with ") and charlists (written with ') are different things. There’s a good introduction in the docs.
String.replace is still going to return a string - the quotes are not part of the value, they are how the value is written literally.
System.get_env expects a string, not a charlist, so it gives you an error if you write System.get_env('VOSK_MODEL')
You need to convert the string value returned from System.get_env into a charlist for the :vosk library - the String.to_charlist/1 function is a good choice for this.

You need to use to_charlist when dealing with Erlang libs…
