  Biru Web Server — Contoh Source Code per Runtime
  https://biru.dot.my.id
============================================================

Setiap folder berisi satu file index yang auto-detect oleh Biru.
Akses URL: https://biru.dot.my.id/nama-runtime/
Biru compile + render otomatis, hasilnya langsung muncul di browser.

------------------------------------------------------------
1. BASH — bash/index.sh
------------------------------------------------------------

#!/bin/bash
VER=$(bash --version 2>&1 | sed -n "s/^GNU bash, version \([0-9.]*\).*/\1/p" | head -1)
echo "Content-Type: text/html; charset=UTF-8"
echo ""
echo "<h1>Hello World</h1>"
echo "<h3>Bash $VER</h3>"

------------------------------------------------------------
2. PERL — perl/index.pl
------------------------------------------------------------

#!/usr/bin/perl
print "Content-Type: text/html; charset=UTF-8\n\n";
print "<h1>Hello World</h1>\n";
print "<h3>Perl " . $^V . "</h3>\n";

------------------------------------------------------------
3. PYTHON — python/index.py
------------------------------------------------------------

#!/usr/bin/python3
import sys
print("Content-Type: text/html; charset=UTF-8")
print()
print("<h1>Hello World</h1>")
print(f"<h3>Python {sys.version.split()[0]}</h3>")

------------------------------------------------------------
4. RUBY — ruby/index.rb
------------------------------------------------------------

#!/usr/bin/ruby
puts "Content-Type: text/html; charset=UTF-8"
puts ""
puts "<h1>Hello World</h1>"
puts "<h3>Ruby #{RUBY_VERSION}</h3>"

------------------------------------------------------------
5. GO — go/index.go
------------------------------------------------------------

package main

import (
    "fmt"
    "runtime"
)

func main() {
    fmt.Println("Content-Type: text/html; charset=UTF-8")
    fmt.Println()
    fmt.Println("<h1>Hello World</h1>")
    fmt.Printf("<h3>Go %s</h3>\n", runtime.Version())
}

------------------------------------------------------------
6. C — c/index.c
------------------------------------------------------------

#include <stdio.h>
#include <stdlib.h>

int main(void) {
    printf("Content-Type: text/html; charset=UTF-8\n\n");
    printf("<h1>Hello World</h1>\n");
    FILE *p = popen("gcc --version | head -1", "r");
    if (p) {
        char buf[128];
        if (fgets(buf, sizeof(buf), p)) {
            printf("<h3>%s</h3>\n", buf);
        }
        pclose(p);
    }
    return 0;
}

------------------------------------------------------------
7. NASM — nasm/index.asm
------------------------------------------------------------

section .data
    ct      db "Content-Type: text/html; charset=UTF-8",10,10
    ct_len  equ $ - ct
    h1      db "<h1>Hello World</h1>",10
    h1_len  equ $ - h1
    h3      db "<h3>NASM 2.15.03</h3>",10
    h3_len  equ $ - h3

section .text
    global _start

_start:
    mov eax, 4
    mov ebx, 1
    mov ecx, ct
    mov edx, ct_len
    int 0x80

    mov eax, 4
    mov ebx, 1
    mov ecx, h1
    mov edx, h1_len
    int 0x80

    mov eax, 4
    mov ebx, 1
    mov ecx, h3
    mov edx, h3_len
    int 0x80

    mov eax, 1
    xor ebx, ebx
    int 0x80

------------------------------------------------------------
8. BRAINFUCK — brainfuck/index.bf
------------------------------------------------------------

Output langsung dari Brainfuck tanpa wrapper shell.
Biru menjalankan bf interpreter, output = CGI response.

Program ini menghasilkan:

    <h1>Hello World</h1>
    <h3>Brainfuck (bf 1.0)</h3>

Kode BF di-generate otomatis dari string ASCII.
Contoh simple "Hi" dalam BF:
    ++++++++[>++++<-]>.

------------------------------------------------------------
9. PASCAL — pascal/index.pas
------------------------------------------------------------

program hello;
begin
    writeln('Content-Type: text/html; charset=UTF-8');
    writeln;
    writeln('<h1>Hello World</h1>');
    writeln('<h3>Pascal 3.2.0 (Free Pascal)</h3>');
end.

Cara kerja: Biru kompilasi .pas -> binary via fpc, lalu eksekusi.

------------------------------------------------------------
10. FORTRAN — fortran/index.f90
------------------------------------------------------------

program hello
    implicit none
    write(*, "(A)") "Content-Type: text/html; charset=UTF-8"
    write(*, "(A)") ""
    write(*, "(A)") "<h1>Hello World</h1>"
    write(*, "(A)") "<h3>Fortran (gfortran 8.5.0)</h3>"
end program hello

Cara kerja: Biru kompilasi .f90 -> binary via gfortran, lalu eksekusi.

------------------------------------------------------------
11. DENO — deno/index.ts
------------------------------------------------------------

console.log("Content-Type: text/html; charset=UTF-8\n");
console.log("<h1>Hello World</h1>");
console.log("<h3>Deno 2.9.5</h3>");

Cara kerja: Biru jalankan via deno run, output = CGI response.

------------------------------------------------------------
12. DART — dart/index.dart
------------------------------------------------------------

void main() {
  print("Content-Type: text/html; charset=UTF-8");
  print("");
  print("<h1>Hello World</h1>");
  print("<h3>Dart 3.13.1</h3>");
}

Cara kerja: Biru kompilasi .dart -> kernel snapshot, lalu eksekusi.
