Basher

Python syntax, native speed. Write Python, get a native Windows program that runs as fast as hand-written C, 7–57× faster than CPython. No type annotations: Basher works out every type when it compiles.

Code

It reads like Python. It runs like C.

def fib(n):
    if n < 2:
        return n
    return fib(n - 1) + fib(n - 2)

print(f"fib(35) = {fib(35)}")

$ basher run fib.bsh            # 31 ms. CPython: 1494 ms
fib(35) = 9227465
$ basher build fib.bsh -o fib   # a standalone fib.exe

Downloads

Served straight from our own machine.

Every file with its sha256, machine-readable: esorlex.com/libary/basher · older versions are listed there too.

Install

Four steps, about a minute.

1. Download setup.exe and run it. It isn't code-signed yet, so Windows SmartScreen may say "unknown publisher": choose More info → Run anyway. No admin rights needed.
2. Answer its questions (Enter takes the default): install folder, add Basher to your PATH, open .bsh files with Basher, the VS Code extension.
3. The C compiler. Basher builds through clang. Setup checks for it and, if it's missing, offers to install LLVM and the Microsoft C++ Build Tools with winget. You see and accept their licenses yourself.
4. Open a new terminal and run basher run hello.bsh (the examples are in the install folder under docs\examples). Later, basher update gets the newest version.

System requirements

Any recent 64-bit Windows PC.

• Windows 10 (1803 or newer) or Windows 11, 64-bit
• clang (LLVM) + Microsoft C++ Build Tools: setup can install both
• About 15 MB for Basher, plus the compiler (about 3 GB with the Build Tools)
• Internet only for downloads, basher install and basher update
• VS Code (optional) for the editor extension
• Linux and macOS: build from source for now; packages later
