While the [last entry](https://github.com/aanastasiou/ptvishash) was in pure [Rhombus](http://rhombus-lang.org), you can use Racket with Rhombus.

Here is a simple example

First my design for the _perfect fish_ in glorious Racket:  
`the-fish.rkt`

```scheme
#lang racket/base
(require pict)
(provide perfect_fish)
(define (perfect_fish n) (standard-fish n (/ n 2)))
(module+ test
  (perfect_fish 100))

```

Lets render this fabulous fish in Rhombus:

`programmers-need-fish.rhm`

```python
#lang rhombus
import:
  pict open
  "the-fish.rkt" open
  
fun the_perfect_fish(w):
  Pict.from_handle(perfect_fish(w))
  
the_perfect_fish(200)

```

You may have noticed that I used an underscore `_` in the `perfect_fish` identifier. This is because `-` is not permitted in shrubbery identifiers:

> _Identifiers_ are formed from Unicode alphanumeric characters plus \_ and emoji sequences,

[https://docs.racket-lang.org/shrubbery/token-parsing.html](https://docs.racket-lang.org/shrubbery/token-parsing.html)

I admit I'm not ready to include emoji in identifiers

For more details see [Using Racket Tools and Libraries](https://docs.racket-lang.org/rhombus-guide/racket.html) in the Rhombus Guide.
