We are pleased to announce Rhombus 1.1 is now available from https://rhombus-lang.org

Rhombus is a general-purpose programming language that is easy to use and uniquely customizable.

As of this release:

• Add annot and annot.def as ways to define an annotation without directly writing meta-time (i.e., macro) code.

• Add as as a binding form, which is sometimes more readable for naming than using && and provides a way to shadow an identifier that is bound as a binding form.

• Change class to bind inherited names using the corresponding superclass or interface reference.

• Change space.enforest to adjust scopes in the same way as for a macro transformer when applying an identifier handler.

• ffi: Add an initialized-array variant of new.

• pict: Change explain_anim to add a ~label_as argument. Change Pict.rebuilt to replace as rebuilt, and also add a ~as_rebuilt argument to select the old or new bevavior. The Pict.rebuild method also supports ~as_rebuilt. Improve magic_move and cross_fade to better handle paragraph points and multiple instances of a child pict.

• slideshow: Add slide_transition and continued page numbering.

Thank you to community members who contributed this release.

Feedback Welcome

Questions and discussion welcome at the Racket community on Discourse or Discord (#rhombus channel)

Anyone can participate in Rhombus design discussions. The Racket team's unofficial motto is anything we can do, you can do: programmers should feel empowered to participate in the creation of the languages they use. Discussions, pull requests, and issues are open to all, and a wide variety of perspectives is especially beneficial. https://github.com/racket/rhombus/blob/master/rhombus/rhombus/HISTORY.txt

Racket - the Language-Oriented Programming Language - version 9.3 is now available from https://download.racket-lang.org

You can use Racket with Rhombus.

Here is a simple example

First my design for the perfect fish in glorious Racket (the language of the gods): the-fish.rkt

#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

#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 Rhombus identifiers:

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

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 in the Rhombus Guide.
