# fn (WIP)
*fn* ([IPA][1]: /fn/) is a functional programming language, a dialect of Lisp
built on top of the [Go](https://golang.org) programming language.
*fn* is still in design phase.
## Early testing
Install the CLI interpreter and feed it with some examples:
```sh
go get github.com/xiam/fnlang/cmd/fn
fn < _examples/001-hello-world.fn
# Hello world!
# [[:nil]]
cat _examples/003-square.fn
# (defn square [x] (* x x))
# (square 10)
# (square 100)
fn < _examples/003-square.fn
# [[:true 100 10000 1000000]]
```
Please note that the CLI is still very rudimentary and it doesn't offer any
REPL capabilities yet:
```sh
echo '(* 34 4 2 3 5 6)' | fn
# [[24480]]
echo '(- 12 34 (+ 3 4 5))' | fn
# [[-34]]
echo '(defn foo [x] [(echo x)]) (foo "hello world!")' | fn
# [[:true ["hello world!"]]]
```
### Examples
#### Fibonacci numbers
```lisp
(defn fib [n]
(when
(= n 0) 0
(= n 1) 1
:true (+ (fib (- n 1)) (fib (- n 2)))
)
)
(fib 0)
(fib 1)
(fib 2)
(fib 3)
(fib 4)
(fib 5)
(fib 6)
```
```
[[:true 0 1 1 2 3 5 8]]
```
