Haskell Support for Qt Creator

This Qt Creator plugin adds basic support for the Haskell programming language.

Features

Syntax highlighting
Basic .cabal project support
Basic build configuration
Basic run configuration

Other editing features like code completion and navigation are provided via haskell-ide-engine and Qt Creator's Language Server Protocol client.

Requirements

Projects

The plugin currently only supports projects using Haskell Stack.

The plugin looks for the stack executable in the default installation directory of the Haskell Stack installers. If this is not correct for you, adapt the path in Options > Haskell.

Linux: Note that Haskell Stack from the Ubuntu distribution and probably others is hopelessly outdated. Use the installers provided by the Haskell Stack project.

Editing

Install haskell-ide-engine for the GHC version that your project uses and configure it in Qt Creator's language client:

Open Options > Language Client
Add a new server
Set Language to the MIME types text/x-haskell, text/x-haskell-project and text/x-literate-haskell
Set Startup behavior to Start Server per Project
Set Executable to hie-wrapper, for example to /home/myself/.local/bin/hie-wrapper
Set Arguments to -lsp

Note that HIE compiles your project before providing any information, so it might take some time.
