How to Concatenate Charlist In Elixir?

a minute read

To concatenate a list of characters in Elixir, you can use the <> operator. This operator can be used to concatenate two lists of characters or a list of characters with a string. Here is an example code snippet to concatenate two lists of characters:

1
2
3
4
charlist1 = 'hello'
charlist2 = 'world'
concatenated_charlists = charlist1 <> charlist2
IO.puts(concatenated_charlists)  # Output: helloworld


In this example, we are concatenating two lists of characters 'hello' and 'world' using the <> operator and storing the result in the concatenated_charlists variable. The IO.puts function is then used to print the concatenated charlist.


How to convert a charlist to a string in Elixir?

You can convert a charlist to a string in Elixir by using the List.to_string/1 function. Here's an example:

1
2
3
charlist = 'hello'
string = List.to_string(charlist)
IO.puts string


This will output:

1
"hello"



What is the precedence of operators when concatenating charlists in Elixir?

In Elixir, the precedence of operators when concatenating charlists is as follows:

  1. ++ (concatenation operator) has higher precedence than + (addition operator)
  2. When concatenating charlists with other operators, it is recommended to use parentheses to clarify the order of operations.


How to reverse a charlist in Elixir?

To reverse a charlist in Elixir, you can simply use the Enum.reverse/1 function. Here is an example:

1
2
3
4
charlist = 'hello'  # 'hello' is a charlist in Elixir
reversed_charlist = Enum.reverse(charlist)

IO.inspect(reversed_charlist)  # Outputs: 'olleh'


In this example, we first define a charlist called charlist with the value 'hello'. We then use the Enum.reverse/1 function to reverse the charlist and store the result in reversed_charlist. Finally, we use IO.inspect to output the reversed charlist.
