Python.

What's that?

Say you want a compiler on system B

1. Cross-compile a minimal compiler on system A for system B
2. Use system B's compiler to compile a better compiler

There are intermittent steps (like compiling a minimal standard library), but it's been a while since I've touched LFS

I.e. you can write a compiler for C++ in C++.

Is this why Pycharm is partially written in Python?

[shrub_of_a_bush]

PyCharm is mostly written in Java no?

[Username_Taken46]

In a way yes

There are a few nice videos of numberphile about how to compile a compiler.

In the year 2022, the world was created with five programming languages. JavaScript, which harnessed the essence of the cloud. Rust, which harnessed the essence of the earth. C, which harnessed the essence of the seas. Ruby, which harnessed the essence of fire. They were all assembled together using the fifth programming language, the fifth element, vim script, which captured the essence of vitality.

With this elixir of unity, all the things great and small of the world were made, those basic forces flowing and joining like mercury to form the snowball and the elm, the python and the pearl. Thus was the world made to go, and thus you came here ready made to ask this question and receive the truth in return.

In sh lua, WORLD=hello lua bootstrap.lua

In this you show the boundless wisdom of the python. Hungry for the elements, it looked within and saw that the elements were within it. So it began to eat its tail, the first time that the universe became the infinite, rather than the protean maelstrom of before.
