HASKELL INTERACTIVE

This extension allows you to execute snippets of Haskell code from within your editor window.

Requirements

This extension uses the interactive GHC interpreter GHCI to execute Haskell code. If you use Stack for managing your projects, you can change the command to start the GHCI interpreter in the extensions settings (haskell-interactive.ghciLaunchCommand)

Usage

Running snippets

Use the haskel-interactive.run_haskell_terminal keybind to send selected snippets to the terminal window (default is Shift+Enter)

If you have text selected when sending the snippet, only that part will be sent to the GHCI terminal. In the example below, only the [] part of the function will be sent to the terminal:

When nothing is selected, the extension will try to capture the entire function that the cursor is in. In the example below, the whole function will be sent to the terminal when pressing the keybind:
