oppi

A typed functional language. Version 0.0.7, under development — both the implementation and the documentation are still moving.

sign : Int -> String
sign n =
  if      n > 0 then "positive"
  else if n < 0 then "negative"
  else               "zero"

Install

Linux x86_64. Installs oppi into ~/.local.

$ curl -fsSL https://oppi-lang.eu/install.sh | sh

> irm https://oppi-lang.eu/install.ps1 | iex

Then oppi --help. The archives and their checksums are at the bottom of the page.

Syntax highlighting and a language server. Install oppi first — the extension relies on it.

$ curl -fsSLO https://oppi-lang.eu/oppi-lsp-0.1.0.vsix && code --install-extension oppi-lsp-0.1.0.vsix

> irm https://oppi-lang.eu/oppi-lsp-0.1.0.vsix -OutFile oppi-lsp-0.1.0.vsix; code --install-extension oppi-lsp-0.1.0.vsix

This site exists to distribute oppi. It does not set out to present or recommend it until the language has been tried over time.
