Sample Prompts
==============

`hg-prompt` supports many keywords, but you probably don't want to use them
all at once. Which keywords you'll find useful depends on the workflow(s) you
commonly use.

Here are some example prompts to get you started.

A Basic Prompt
--------------

A very simple prompt could tell you:

* Which named branch you're currently working on.
* If there are any uncommitted changes in the working directory.
* If you're at a revision that's not a branch tip (i.e. if running `hg update`
  would do something).

To get a prompt like this you could add this to your `~/.bashrc` file:

    :::bash
    export PS1='\u in \w`hg prompt "{on {branch}}{status}{update}" 2>/dev/null` $'

The result would look something like this:

    :::text
    username in ~/src $ cd project
    username in ~/src/project on feature-branch $ touch sample
    username in ~/src/project on feature-branch? $ hg add sample
    username in ~/src/project on feature-branch! $ hg commit -m 'Add a file.'
    username in ~/src/project on feature-branch $ hg update default
    username in ~/src/project on default $ hg update 0
    username in ~/src/project on default^ $

The `2>/dev/null` part of the prompt command prevents errors from showing when
you're not currently in a Mercurial repository.

The keywords (`{branch}`, `{status}` and `{update}`) display the relevant
information.

The extra text in the `{branch}` keyword will only display if a branch exists,
so you won't see the word "on" if you're not in a repository.

A More Compact Basic Prompt
---------------------------

Some people prefer a smaller, less obtrusive prompt. To get that kind of
prompt you can omit some of the less important text:

    :::bash
    export PS1='\w`hg prompt "[{branch}{status}{update}]" 2>/dev/null` $'

That will give you something like this:

    :::text
    ~/src $ cd project
    ~/src/project[feature-branch] $ touch sample
    ~/src/project[feature-branch?] $ hg add sample
    ~/src/project[feature-branch!] $ hg commit -m 'Add a file.'
    ~/src/project[feature-branch] $ hg update default
    ~/src/project[default] $ hg update 0
    ~/src/project[default^] $
