Usage
=====

The `hg prompt` command takes a single string as an argument and outputs it.  Here's a simple (and useless) example:

    :::console
    $ hg prompt "test"
    test

Keywords in curly braces can be used to output repository information:

    :::console
    $ hg prompt "currently on {branch}"
    currently on default

Keywords also have an extended form:

    :::text
    {optional text{branch}more optional text}

This form will output the text and the expanded keyword **only** if the keyword successfully expands.  This can be useful for displaying extra text only if it's applicable:

    :::console
    $ hg prompt "currently on {branch} and at {bookmark}"
    currently on branch default and at 
    
    $ hg prompt "currently on {branch} {and at {bookmark}}"
    currently on branch default 
    
    $ hg bookmark my-book
    
    $ hg prompt "currently on {branch} {and at {bookmark}}"
    currently on branch default and at my-book

Take a look at the [keywords][] documentation to see all the keywords `hg-prompt` supports.
