idris2-effects

Port effects package from Idris 1 to Idris2

My learning experience with Algebraic Effects and Idris2.

Setup and run the examples

You don't need to install Idris2 or idris2-lsp, those tools are already installed in devcontainer. All you need to setup in your computer are:

Docker
VSCode
Remote Development Extension Pack for VSCode

Then checkout the code locally:

git clone https://github.com/jiwhiz/idris2-effects.git

In VS Code, open the project folder. Since it has dev container config, VS Code will prompt on the bottom right with:

Click "Reopen in Container" and it will download the image and open the project in a devcontainer. Make sure you have docker running locally, and see the new container running.

Open a new Terminal in VS Code, and you can check the idris2 and idris2-lsp version:

vscode ➜ /workspaces/idris2-effects $ idris2 --version
Idris 2, version 0.6.0-dc1b5387b
vscode ➜ /workspaces/idris2-effects $ idris2-lsp --version
Idris2 LSP: 0.1.0-7fa662a2a
Idris2 API: 0.6.0-dc1b5387b

You can try the examples inside Idris REPL, such as TreeLabel.idr:

vscode ➜ /workspaces/idris2-effects $ idris2 src/Examples/TreeLabel.idr

Welcome to Idris 2.  Enjoy yourself!
