Try Out Development Containers: Haskell

This is a sample project that lets you try out the VS Code Remote - Containers extension in a few easy steps.

Note: If you're following the quick start, you can jump to the Things to try section.

Setting up the development container

Follow these steps to open this sample in a container:

1. If this is your first time using a development container, please follow the getting started steps.

2. Linux users: Update USER_UID and USER_GID in .devcontainer/Dockerfile and "runArgs": [ "-u": "1000" ] in .devcontainer/devcontainer.json with your user UID/GID if not 1000 to avoid creating files as root.

3. If you're not yet in a development container:

   • Clone this repository.
   • Press F1 and select the Remote-Containers: Open Folder in Container... command.
   • Select the cloned copy of this folder, wait for the container to start, and try things out!

Things to try

Once you have this sample opened in a container, you'll be able to work with it like you would locally.

Note: This container runs as a non-root user with sudo access by default. Comment out "runArgs":["-u", "1000"] in .devcontainer/devcontainer.json if you'd prefer to run as root.

Some things to try:

1. Edit:
   • Open src/Main.hs
   • Try adding some code and check out the language features. Notice that you can hover over variables to see their type and Haddock information.
2. Terminal: Press Ctrl+Shift+` and type uname and other Linux commands from the terminal window.
3. Build, Run, and Debug:
   • Ctrl+Shift+p and type run to run the current application with stack
   • Ctrl+Shift+b will build with stack
