💅 realcsh — binfmt_C's own little C++ party shell ✨

okay bestie, buckle up, because this is realcsh(1) from the binfmt_C corner of the manual-page multiverse, and she is serving interactive C++ realness 💖

---

🌸 NAME 🌸

realcxxsh.c — literally a shell for running C++ code. that's it, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

realcxxsh.c [g++ options]

so yeah, you just run it, and you can throw any g++ options at it like confetti 🦋

---

💜 DESCRIPTION 💜

okay so realcsh.c is an interactive shell that runs C++ source code. the way it works is iconic: every line you type in gets handled as a line inside the main() function, then the resulting C++ code gets compiled, and then it gets executed. boom. no cap 🔥

and here's the cute part — if you enter a line that starts with #, like #include <iostream>, that line gets added to every code after that, right at the start of the sourcecode 👑

want to see the list of all those #-lines you've collected? just type ## and she'll show you the whole stash 💅

---

🌈 EXAMPLES 🌈

here's what a session looks like, bestie:

$ ./realcxxsh.cc
REAL c++sh: cout << "Hello world0;
Hello world
REAL c++sh: system ("pwd");
/home/dancer
REAL c++sh:

see? you type the C++ line, she compiles, she runs, she slays 🫶

---

🧚 INTERNALS 🧚

and this is what the C++ code actually looks like behind the scenes, like the little skeleton under the outfit:

/*BINFMTCXX:
*/
#include <iostream>

int main(int argc, char ** argv)
{
input-line
return 0;
}

your input line drops right into the middle of main(). main character energy, fr fr 👑
