A progressive, step-by-step guide to kvlang.
Each numbered directory contains a standalone main.kv you can run immediately.
08-algo/ is a collection of complete programs — run any file directly.
| Step | Topic | What you'll learn |
|---|
| 01-hello | Hello World | print, terminal activation |
| 02-vars | Variables | path-based read/write (./x) |
| 03-arith | Arithmetic | + - * /, pow, sqrt, abs, max, min |
| 04-func | Functions | def, call, arguments, write params |
| 05-if | Conditionals | if/else, boolean operators && || ! |
| 06-while | While Loops | while, break, continue |
| 07-recursion | Recursion | multi-write params, tail-call optimization |
| 08-algo/ | Algorithms | fibonacci, fizzbuzz, gcd, collatz, … |
# numbered steps — each prints its own output

kvlang tutorial/06-while/main.kv
# ...# algo showcase — any file is self-contained
kvlang tutorial/08-algo/fibonacci.kv # fib = 55
kvlang tutorial/08-algo/fizzbuzz.kv # FizzBuzz 1-15
kvlang tutorial/08-algo/gcd.kv # gcd = 6
kvlang tutorial/08-algo/collatz.kv # steps = 111
| File | Algorithm | Key concepts |
|---|
fibonacci.kv | Iterative Fibonacci | while, variable swap |
factorial.kv | Iterative Factorial | while accumulator |
fizzbuzz.kv | FizzBuzz 1–15 | modulo, nested if |
gcd.kv | GCD (Euclidean) | tail recursion |
power.kv | Fast power (loop) | while, counter |
classify.kv | Grade classifier | nested if, string literal |
collatz.kv | Collatz conjecture | while, even/odd branch |
