This is cool although for practical purposes, I think most people who need such a tool will not be using Haskell. It is tempting me to add Haskell to my CI just because it looks so nice and easy to use.

Many people writing documents as text files use Pandoc, which is one of the most popular tools written in Haskell.

[michaelmior]

I didn't realize Pandoc was written in Haskell :)

[nick_meister]

Pardon my ignorance about compilers, Haskell, and programming in general (I have no background in CS, please don't roast me :), but cannot the Glasgow Haskell Compiler (GHC) produce a (binary executable) package that could run in Linux/Windows without having Haskell?

[nh2]

Yes, and the announcement even says:

"Binaries for Mac and Linux are available."

[michaelmior]

Except the latest release has only a binary for macOS.

[shcollider]

Sorry about that, have built a Linux version now. (There wasn't a Docker container available for the build file I'd used at the time)

[michaelmior]

No problem at all. Thanks!

[detaro]

still doesn't mean you need Haskell in your CI environment.

[michaelmior]

Correct. I didn't say I needed it. I just suggested that I might do this.

[nh2]

Why would you have to "add Haskell to your CI" to run the tool?

You also don't have to install C++ and Rust compilers to be able to run Firefox, or a Haskell compiler to run Pandoc.

[michaelmior]

Very true although the latest binary is only released for macOS.

[daveFNbuck]

It seems all you miss by getting the previous version is the --no-color flag.

[blondin]

interesting. is haskell that big? don't they have a docker image you can pull in?

i know python and node and other languages have small images you can get for the CI situation you describe.

[rnhmjoj]

GHC is notoriously large. The compiler itself is around 1.5GB (this includes documentation, static and dynamic libraries).

To get an idea of the size of the bare-minimum system that's required to develop in language x, you can look at the cumulative sizes of the Nix package closures. This is what I get for ghc, nodejs and python3:

    λ nix path-info -rS nixpkgs.ghc | awk '{s+=$2}END{print s/1073741824 " GB"}'
    3.35463 GB

    λ nix path-info -rS nixpkgs.nodejs | awk '{s+=$2}END{print s/1073741824 " GB"}'
    1.05813 GB

    λ nix path-info -rS nixpkgs.python3 | awk '{s+=$2}END{print s/1073741824 " GB"}'
    0.485017 GB

I started installing haskell a lil while ago with macports but I got as far as

bash$ port rdeps ghc

The following ports are dependencies of ghc @8.8.3_0:

And decided to give it a miss.

That seems to be a packaging issue with MacPorts. It looks like it's including build dependencies, too. It's pulling TeX Live and the Sphinx Python bindings for formatting documentation. I'm not sure what Perl is for, or why it needs 3 different versions of Python.

The Debian package doesn't require any of those. The Homebrew package has no dependencies at all (and only "python" and "sphinx-doc" as build dependencies).

[read_if_gay_]

On Arch Pandoc “only” requires a few dozen or so Haskell packages. Installing it does kind of mess up pacman’s output when updating etc, but that’s a very minor annoyance for a pretty useful tool to me.
