Convert Binary to Text [duplicate]

Question

Your task is to write a program, which takes a binary input and converts it to plain text. For Example:

01100001 01100010 01100011 = "abc"

Rules

• Input can come from STDIN, function arguments, command line argument, file, whatever suits you.
• The program can be a function, full program, whatever works, really, as long as no external uncounted code/arguments are needed to run it.
• You can assume that the input is valid.
• The length of the input is not limited
• You can assume that all blocks are seperated with whitespaces

Test Cases

01010100 01100101 01110011 01110100 = "Test"
01001000 01100101 01101100 01101100 01101111 = "Hello"
01010111 01101111 01110010 01101100 01100100 00001101 00001010 = "World"
01000101 01111000 01100001 01101101 01110000 01101100 01100101 00001101 00001010 = "Example"
01100010 01101001 01101110 00001101 00001010 = "bin"

This is code-golf, so the shortest solution wins.

Answer 1

dc, 4 bytes

Needs as input the binary blocks with no separator. This is allowed by the OP.

2i?P

Explanation: using the "abc" example as test case

• 2i? sets 2 as input radix, then reads the line (output radix is 10 by default). This converts the binary input to decimal: 011000010110001001100011 -> 6382179.
• P is a special printing mode that assumes a base 256 number, using its "digits" as ASCII codes: 6382179 = (97 * 256 ²) + (98 * 256 ¹) + (99 * 256 ⁰) -> abc

Explanation

l    e# Read input.
:~   e# Evaluate each character, resulting in a flat list of bits.
8/   e# Split into chunks of 8 bits.
2fb  e# Convert each from binary to an integer.
:c   e# Convert each integer to a character.

{split|chr parseInteger(_,radix=2)}

Try it online!

This is an anonymous function that reads the input from the stream and prints the result.

It uses three builtins:

• split splits the input at whitespaces
• parseInteger converts a binary string to an integer value
• chr converts an integer to a Unicode character

Gema, 33 characters

<D><s>=@int-char{@radix{2;10;$1}}

Sample run:

bash-4.3$ gema '<D><s>=@int-char{@radix{2;10;$1}}' <<< '01010000 01010000 01000011 01000111'
PPCG

Gema, 31 characters

Using no delimiter in the input.

<D8>=@int-char{@radix{2;10;$1}}

Sample run:

bash-4.3$ gema '<D8>=@int-char{@radix{2;10;$1}}' <<< '01010000010100000100001101000111'

PHP <5.3, 53 Bytes

Idea by @manatwork

foreach(split(" ",$argv[1])as$v)echo chr(bindec($v));

PHP, 55 Bytes

I prefer cause it can work without spaces

foreach(str_split($argv[1],9)as$v)echo chr(bindec($v));

without spaces change 9 to 8 for 7 bits 7

foreach(explode(" ",$argv[1])as$v)echo chr(bindec($v));

PHP >=7, 62 Bytes

<?=join(($a=array_map)(chr,$a(bindec,explode(" ",$argv[1]))));

Answer 16

Jelly, unfinished

I still haven't figure out how to repeat for every line in STDIN, or get amount of lines in STDIN in Jelly. So far though, I came up for a solution for a single line/character.
