Directly execute C source code by embedding in a bash script.

hello-world.shc

#!/bin/bash
COMPILER_OPTIONS="-g -Wall -Wextra --std=c11 -O1 -fsanitize=address,undefined"
SOURCE_CODE=$(cat <<'END_OF_SOURCE_CODE'

#include <stdio.h>

int main() {
  printf("Hello world!\n");
  return 0;
}

END_OF_SOURCE_CODE
);THIS_FILE="$(cd "$(dirname "${BASH_SOURCE[0]}")"; pwd -P)/$(basename "${BASH_SOURCE[0]}")"
OUT_FILE="/tmp/build-cache/$THIS_FILE"; mkdir -p "$(dirname "$OUT_FILE")"; set -e; 
test "$THIS_FILE" -ot $OUT_FILE || $(which clang || which gcc) $COMPILER_OPTIONS -xc -o "$OUT_FILE" - << END_OF_COMPILER_INPUT
#line 4 "$THIS_FILE"
$SOURCE_CODE
END_OF_COMPILER_INPUT
exec -a "$0" "$OUT_FILE" "$@"
