PS1 prompt in fish (Friendly Interactive SHell) show git branch

Question

In Bash I have my PS1 as

PS1="u@h:w$(git branch 2>/dev/null | grep -e '* ' | sed 's/^..(.*)/{1}/') $ "

Which will show my current git branch if I am in a git repo.

How do I set the PS1 in fish so it will show me my current git branch?

@glenn already got the answer, but I've found a simpler way of showing the git prompt on fish.

From the terminal, in fish, type fish_config. This will open a browser window. Select the second tab prompt and under there select Classic + Git`.

This will show the commands required to show Git on the terminal prompt. Copy them to your ~/.config/fish/config.fish or even simpler: click on "Use prompt".

How awesome is that?
