# Haskell `haskell`

!!! important "This section is rendered asynchronously by default"

!!! info
    [**Haskell**](https://www.haskell.org) is a general-purpose purely functional programming language, with non-strict semantics.

The `haskell` section displays the version of the Haskell compiler.

This section is displayed only within Haskell projects, meaning:

* Upsearch finds a `stack.yaml` file.
* The current directory contains a file with `.hs` or `.cabal` files.
