Let's teach about our passion

I'm building books.

But, by teaching, I'm also building
a community.

Teaching is building.

One day, all Haskell programmers outgrow tutorials. Haddock is more than enough, right?

Haskell is awesome enough to have some very expressive types that tell you how to work your way through the library that you're using.

But Haddock is API documentation, which is a kind of hard documentation. (Hard as in granite)

Let's face it, there are a lot of people out there trying to reach that point. People like to get things done, and to do so, they have to use awesome libraries like yours. And to do so, they consume lots of tutorials and guides, which are a kind of soft documentation.

Also, not everyone has the time of maintaining a super great library and also a website for hosting the documentation. Some users would like to do so, but also, why creating a site from scratch for your package, when they can do so in their own blog?

Tintin handles all of that

Tintin is a utility to create a soft documentation website for your Haskell project. All documentation blocks are compiled through GHC to ensure that there are no compilation errors.

Forget about creating a website, just write your tutorials using markdown. Host them on Github pages.

And it's a piece of cake:

---

• 1. Put your documentation into the doc folder
• 2. Install the tintin dependencies
• 3. Execute tintin run

---

Code correctness

Tintin runs the GHC Haskell compiler over all of your documentation files, ensuring that everything is correct.

Each one of your code blocks is typechecked and compiled, meaning that your documentation won't get outdated, as it depends on your code:

{-# LANGUAGE OverloadedStrings #-}
import Data.Text as Text

protocol :: Text -> Text
protocol = Text.takeWhile (/= ':')

Inline examples

You can also evaluate code in your documentation, meaning that your users will know what to expect from your examples:

protocol "https://github.com/theam/tintin" => 
https
