To convert a bitstring into a string in Elixir, you can use the to_string/1
function. This function converts a binary to a UTF-8 encoded string. You can simply pass the bitstring as an argument to the to_string/1
function, and it will return the corresponding string representation. For example:
1 2 3 |
bitstring = <<104, 101, 108, 108, 111>> string = to_string(bitstring) IO.puts(string) # Output: "hello" |
Keep in mind that the to_string/1
function expects the binary to be valid UTF-8 encoded data. If the bitstring contains invalid UTF-8 characters, it may throw an error.
How to convert a bitstring into a utf-16 encoded string in Elixir?
You can convert a bitstring into a utf-16 encoded string in Elixir by using the :binary.bin_to_list/1
function to convert the bitstring into a list of bytes, and then using the :unicode.characters_to_binary/1
function to convert the list of bytes into a utf-16 encoded binary.
Here is an example code snippet demonstrating this conversion:
1 2 3 4 5 6 |
bitstring = <<72, 101, 108, 108, 111>> # Bitstring representing "Hello" bytes_list = :binary.bin_to_list(bitstring) utf16_encoded = :unicode.characters_to_binary(bytes_list, :utf16) utf16_encoded_string = String.to_charlist(utf16_encoded) IO.puts(utf16_encoded_string) # Output: [72, 0, 101, 0, 108, 0, 108, 0, 111, 0] |
In this example, the bitstring <<72, 101, 108, 108, 111>>
represents the ASCII characters "Hello". The :binary.bin_to_list/1
function converts the bitstring into a list of bytes, which is then converted into a utf-16 encoded binary using :unicode.characters_to_binary/2
. Finally, the utf-16 encoded binary is converted into a list of characters using String.to_charlist/1
.
How to convert a bitstring into a unicode string in Elixir?
You can convert a bitstring into a unicode string in Elixir by using the :binary.decode_unsigned
function from the :binary
module. Here's an example of how to do this:
1 2 3 4 5 |
bitstring = <<104, 101, 108, 108, 111>> # bitstring representing "hello" unicode_string = :binary.decode_unsigned(bitstring, :utf8) IO.puts unicode_string # Output: "hello" |
In this example, we first define a bitstring bitstring
representing the ASCII characters for "hello". We then use the :binary.decode_unsigned
function to decode the bitstring as a UTF-8 encoded Unicode string. Finally, we print out the resulting Unicode string using IO.puts
.
Note that you may need to specify a different encoding depending on the encoding of the bitstring you are working with. The :binary.decode_unsigned
function supports various encoding options such as :utf8
, :utf16
, :latin1
, etc.
How to convert a bitstring into a lowercase string in Elixir?
You can convert a bitstring to a lowercase string in Elixir by using the String.downcase/1
function. Here is an example of how you can achieve this:
1 2 3 |
bitstring = <<72, 69, 76, 76, 79>> lowercase_string = bitstring |> :binary.bin_to_list() |> Enum.map(&(String.downcase([Enum.at(&1, 0)]))) |> List.to_string() IO.puts(lowercase_string) |
In this example, we first convert the bitstring to a list using the :binary.bin_to_list/1
function. Then, we map over the list elements and convert each element to lowercase using the String.downcase/1
function. Finally, we convert the list back to a string using List.to_string/1
function.
The output of this code will be:
1
|
"hello"
|
