Overview

"haskell-linter" is a wrapper for hlint. It highlights hlint warnings and errors inline and provides a code-action to accept hlint suggestions.

Dependencies

It expects a version of hlint >= 1.9.1 to be installed and already added to the path. If it is installed but cannot be found, add the path to your preferences as seen below.

{
	"haskell.hlint.executablePath": "Path\To\Executable"
}

IDE

Configuration:

There are various options that can be configured by making changes to your user or workspace preferences.

Lint onType or onSave

By default the linter will lint as you type. Alternatively, set haskell.hlint.run to onSave or never if you want to lint only when the file is saved (works best if auto-save is on) or disable it for a workspace or entirely.

{
	"haskell.hlint.run": "onType" // also: "onSave", "never"
}

Hints

By default the linter simply calls the hlint command without arguments. To specify a set of hints to use or a set of hints to ignore, add them to the configuration as shown below.

{
	"haskell.hlint.hints": ["Default", "Dollar", "Generalise"],
    "haskell.hlint.ignore": ["Redundant do"]
}

Troubleshooting

Make sure you have a hlint installed and that the version is 1.9.1 or newer. If you're having issues with the extension, set the logLevel setting to log and check the output in the developer tools console.

{
    "haskell.hlint.logLevel": "log"
}

Acknowledgements

The extension architecture is based off of the PHPValidationProvider from the built-in php extension.
