Gren programming language, a playground for curiosity and fun

https://gren-lang.org/ && https://github.com/gren-lang

It's in 0.3.0 at time of writing (February 2024)

Notes:

• it's available as a NPM package
• if you don't have or don't like NPM, there are prebuilt binaries and compile from source options
• takes code style and ideas from functional paradigms
• carefully managed side-effects
• a strong static type system
• "Compiler as an assistant" philosophy, I thought it was on par with rustc (the error messages were perfect when I was coding this)

Claims :

• to be both smaller and faster than your average React-based application

Resources :

• https://gren-lang.org/install

xdg-open http://localhost:8080

Or if you are a weak gui-clicker 😄 : you can manually open a browser tab and go to http://localhost:8080

Try with local install

Requirements : git

pre-compiled binary at their github https://gren-lang.org/install

or if you don't trust nothing (as you should), build compiler yourself from source code https://github.com/gren-lang/compiler

git clone git@github.com:Neal-C/hello-gren.git
cd hello-gren
gren make src/Hello.gren
# and open the resulting 'index.html' file
