Yesod tutorial from 4th São Paulo Haskellers Meeting

Welcome! This is the repo of the tutorial that was presented on the 4th São Paulo Haskellers Meeting by Felipe Lessa (@meteficha).

To prepare your environment, you'll need to:

1. Install the Haskell Platform.

2. Update your Cabal database by running cabal update.

3. Install the Yesod Platform version 1.2 by running cabal install yesod-platform-1.2.0.1 yesod-bin persistent-sqlite esqueleto. Note that by the time you follow these instructions there may be a more recent version of the Yesod Platform, but this tutorial has been written with this one mind.

4. Clone this repo to your machine.

5. Finally, checkout the first checkpoint by using git checkout -f checkpoint-00.

How to follow this tutorial

This tutorial has the concept of checkpoints. Each checkpoint is a git branch. You'll use the checkpoints in order to advance through the tutorial. At all times, just check the file TODO.md in order to see what is your current task.

To go to the first checkpoint, just run git checkout -f checkpoint-00. Now open TODO.md and continue from there =).

After completing a checkpoint's task, you may want to compare your code with the solution in the repo. For example, if you are on checkpoint-07, you should run git diff checkpoint-08 in order to see how your solution differs from the repo's one.

If you're satisfied with your solution and want to follow to the next checkpoint, then commit your progress for future reference using git commit -a -m 'My progress' and checkout the next checkpoint using git checkout -f checkpoint-XX, where XX is the number of the next checkpoint. (Use git branch to see your current checkpoint.) Your modifications will be thrown away and you'll go on with the tutorial's code.
