Given a string, output the hexdump of the string as given by the xxd utility using the default settings, as described below.

Divide up the input string into groups of 16 bytes (16 octets). For each group, print in order:

  • The (hexadecimal, lowercase) index of the starting octet, padded with zeros to eight hexadecimal digits
  • A single colon (:), followed by a single space.
  • 8 space-separated pairs of octets, with each pair printed as 4 hexadecimal digits
  • Spaces to pad to 51 bytes
  • The original 16 bytes, except with newline replaced with full stop (.)
0 bytes, 0 chars

Compiled from AT&T syntax to x86-64 Linux. Use syscalls to write output.
Top-level programs are supported, args holds ARGV. Implicit using directives for console applications are enabled.
Arguments are available via STDIN, each argument is NULL terminated. Taking input after EOF leaves the cell unchanged, the tape is circular with 65536 cells, and cells are 8-bit with wrapping.
Code is compiled with clang with -std=c++2b.
Code is compiled with LDC2.
Arguments are available via STDIN, each argument is NULL terminated. x is a no-op.
The stack is initialized with an array containing arguments, rather than the contents of STDIN.
Arguments are available via STDIN, each argument is NULL terminated.
arguments holds ARGV, print() to output with a newline, write() to output without a newline.
Code is run under -E, all current features are enabled.
$args to access the arguments.
prolog_flag(argv, Args) to access the arguments.
Arguments are available via STDIN, each argument is seperated with a null byte. The code is run with -E and -z. Output replaces null bytes with newlines.
SELECT arg FROM argv to access the arguments, only the first column of the first result set will be printed, NULL values will be skipped, and the dialect is SQLite.
Arguments are available via args list variable. To terminate script execution, write and quit the current buffer.

Are you sure you want to delete your solution(s) for Hexdump?

If you have seperate bytes and chars solutions then both will be deleted.

This is irreversible, please backup any code you care about.
