Creating a clean gh-pages branch

This is the sequence of steps to follow to create a root gh-pages branch. It is based on a question at [SO]

cd /path/to/repo-name
git symbolic-ref HEAD refs/heads/gh-pages
rm .git/index
git clean -fdx
echo "My GitHub Page" > index.html

import GHC.Exts ( IsString(..) )

data Foo = A | B | Other String deriving Show

instance IsString Foo where
  fromString "A" = A
  fromString "B" = B
  fromString xs  = Other xs

Undo/Redo

Undo/Redo is one of those features of an application that you almost always need to have if you are building serious GUI tools for people to do work.

The best way to look at undo/redo is two stacks of operations the user has performed:

• The Undo stack is the "history" of what they've done
• The redo stack is the breadcrumbs back to the initial state before they started undoing
