- Rye language 🌾

Rye is a high level, dynamic programming language based on ideas from Rebol, flavored by Factor, Linux shells and Golang. It's still an experiment in language design, but it should slowly become more and more useful in real world.
It features a Golang based interpreter and console and could also be seen as (modest) Go's scripting companion as Go's libraries are quite easy to integrate, and Rye can be embedded into Go programs as a scripting or config language.
I believe that as language becomes higher level it starts touching the user interface boundary, besides being a language we have great emphasis on interactive use (Rye shell) where we will explore that.
Core ideas of the language are formed. Most experimenting, at least at this stage, is done. Right now, focus is on making the core and runtime useful for anyone who might decide to try it.
This means we are improving the Rye console, documentation and improving the runtime and core functions.
Rye is homoiconic, it has no keywords or special forms (everything is a function call, everything is a value), everything returns something (is an expression), has more syntax types than your usual language, functions are first class citizens, so are blocks of code and scopes (contexts). It has multiple dialects (specific interpreters).
Although it seems contrary to each other Rye tries to be very flexible but also safer where possible. For example, it doesn't even have a syntax for changing state directly outside current context (parent or sub). It separates between pure and impure functions, while most of builtins are pure. Validation dialect is part of its core, so input validation is easy and distinguishable/explicit, not sprinkled around other code. Few functions that change state in place end with "!" (and usually don't need to be used). Functions never return null, they return result or a specific failure (which is a Rye value too, and you can handle on-specific-spot).
print "Hello World"
"Hello World" .replace "World" "Mars" |print
; prints: Hello Mars
"12 8 12 16 8 6" .load .unique .sum
; returns: 42
{ "Anne" "Joan" "Adam" } |filter { .first = "A" } |for { .print }
; prints:
; Anne
; Adam
fac: fn { x } { either x = 1 { 1 } { x * fac x - 1 } }
; function that calculates factorial
range 1 10 |map { .fac } |print\csv
; prints: 1,2,6,24,120,720,5040,40320,362880,3628800
kind: "admin"
open sqlite://data.db |query { select * from user where kind = ?kind }
; returns: Spreadsheet of admins
read %name.txt |fix { "Anonymous" } |post* https://example.com/postname 'text
; makes HTTP post of the name read from a file, or "Anonymous" if file failed to be readVisit this set of pages to find out more (work in progress):
These pages are littered with examples. You can find them on this README page, on our blog, on Introductions, but also:
- Examples folder - unorganized so far, will change
- Solutions to simple compression puzzle
Rye's focus is also interactive use. Check out these asciinema demos:
Python is the lingua franca of dynamic programming languages, so comparing examples in Python and Rye can be helpful to some:
The author of Factor once said that at the end it's not about the language, but the libraries. I can only agree, adding libraries, and distribution.

Fyne is a cross platform pure Go GUI toolkit that we integrated into Rye. Gio is immediate mode GUI library for Go, and Ebitengine is a 2D game endgine for Go.

This is another place for updates and also potential discussions. You are welcome to join our reddit group.
If code speaks to you, our Github page is the central location for all things Rye. You are welcome to collaborate, post Issues or PR-s, there are tons of things to do and improve :)
Rye is developed and should work on Linux and Mac and Windows. We also have a Docker and as WASM modules. If you need additional architecture or OS, post an Issue. Rye could run anywhere Go compiles to.
You can find precompiled Binaries for Linux and macOS under Releases.
Docker images are published under Packages.
Rye is avaliable for instalation through brew command: brew install ryelang
More about it: Homebrew formulae
This image includes Linux, Rye binary ready for use and Emacs-nox editor.
Docker image: ghcr.io/refaktor/rye
Run it via:
docker run -ti ghcr.io/refaktor/ryeThe repository comes with a local Docker image that builds rye and allows you to do so.
docker build -t refaktor/rye -f .docker/Dockerfile .Run 🏃♂️ the rye REPL with:
docker run -ti refaktor/ryeUse official documentation or lines below to install Golang 1.21.5 https://go.dev/doc/install (at the time of writing):
wget https://go.dev/dl/go1.21.5.linux-amd64.tar.gz
rm -rf /usr/local/go && tar -C /usr/local -xzf go1.21.5.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
go version
Clone the main branch from the Rye repository:
git clone https://github.com/refaktor/rye.git && cd rye
Build the tiny version of Rye (with minimal modules):
go build -tags "b_tiny" -o bin/rye
Build the normal version of Rye (with most "batteries" packed in):
go build -o bin/rye
# or just run
./build
Run the rye file:
bin/rye hello.rye
Run the Rye Console
bin/rye
Install build-essential if you don't already have it, for packages that require cgo (like sqlite):
sudo apt install build-essential
Rye can also work inside your browser or any other WASM container. I will add examples, html pages and info about it, but to build it:
GOOS=js GOARCH=wasm go build -tags "b_tiny" -o wasm/rye.wasm main_wasm.go
# or just use
./buildwasm
# which will also start a webserver, visit http://localhost:8085/ryeshell/ then
Run the Rye code tests.
cd tests
../bin/rye main.rye test
Build the function reference out of tests:
cd tests
../bin/rye main.rye doc
Rye has Syntax highlighting for Emacs and VS Code. For VS Code just search for ryelang in the Extension marketplace. For Emacs it will be published soon on github.
- Rye-fyne - external binding for Fyne GUI toolkit (wip)
- Rye-ebitengine - external binding for Ebitengine game engine (wip)
- ryegen - Rye binging generation toolkit (wip)
Rebol - Rebol's author Carl Sassenrath invented or combined together 90% of concepts that Rye builds upon.
Factor - Factor from Slava Pestov taught me new fluidity and that variables are no-good, but stack shuffle words are even worse ;)
Red - Another language inspired by Rebol from well known Rebol developer DocKimbel and his colleagues. A concrete endeavor, with its low level language, compiler, GUI, ...
Oldes' Rebol 3 - Rebol3 fork maintained by Oldes (from Amanita Design), tries to resolve issues without unnecessarily changing the language itself.
Ren-c - Rebol 3 fork maintained by HostileFork, more liberal / experimental with changes to the language.
Arturo - Another unique language that builds on Rebol's core ideas.
