promptmanager

A bash prompt manager with themes, colors and dynamic elements. This is useful so that your prompt reflect the environment you are in like debug mode or python virtualenv. Usually, these just add element to your PS1, no colors, no question where to add it. That's where the prompt manager is useful.

Example use

Currently

Suppose your have such prompt :

[username@hostname:~]$

Then you activate a python virtualenv named pydev, your prompt look like so without color to (pydev) :

(pydev)[username@hostname:~]$

With promptmanager

Since the default might not be what you want, promptmanager give the tools to get what you want. If you tweek the activate script, your prompt might be colored including the pydev and look like so :

[username@hostname:~][pydev]$

It can be easily set to your liking, but by default the prompt is configured like so :

[Mer nov 07 (04:38 ) on tty0][0|1zZ]
[username@hostname ~]$

If you source the above mentioned virtualenv activate script and some other script that set you in debug mode you'll end up with a prompt like so :

[Mer nov 07 (04:38 ) on tty0][0|1zZ][pydev][debug]
[username@hostname ~]$

Try

To try, from bash, you can source like so:

source promptmanager
source promptrc

Add a DEBUG element to your prompt :

PS1_Push_Element debug DEBUG

Change your theme :

PS1_Theme Hulk

Remove the debug element:

PS1_Pop_Element debug

Usage (Interface)

When you want to set a state in the prompt, use these methods to add/remove elements dynamically from your script. This will add support for promptmanager.

# Add element
if `declare -f PS1_Push_Element > /dev/null`
then
    PS1_Push_Element debug DEBUG
else
    _old_PS1=$PS1
    PS1="(stuff you want to add)$PS1"
fi

#Remove Element
if `declare -f PS1_Pop_Element > /dev/null`
then
    PS1_Pop_Element debug
else
    PS1=$_old_PS1
fi

gnome

In gnome terminal, each terminal has a title.

By default it sets the title to the current theme name. You can also set it yourself:

PS1_Theme Bunny "Use this terminal for work"

It does not seam easy to detect that you are using gnome-terminal. So if it annoy you, you can tell that you are not using it:

gnome_terminal=false PS1_Theme BnW

Configure

Set a default prompt

This is the prompt you will get by default

PS1_Clear
PS1_Push_Widget '\[$PS1_COLOR_LOW\]\d (\[$PS1_COLOR_MEDIUM\]\@\[$PS1_COLOR_LOW\]) on tty\l'
PS1_Push_Widget '\[$PS1_COLOR_HIGH\]$?\[$PS1_COLOR_BRACKET\]|\[$PS1_COLOR_HIGH\]\j\[$PS1_COLOR_LOW\]zZ'
PS1_Push_Dynamic_Content
PS1_Push_NewLine
PS1_Push_Widget '\[$PS1_COLOR_USER\]\u\[$PS1_COLOR_BRACKET\]@\[$PS1_COLOR_HOST\]\h \[$PS1_COLOR_MEDIUM\]\W'

Also set a PS2

Not yet themable except for colors, but no one really want to add content dynamically to PS2

PS1_PS2='"\[$PS1_COLOR_BRACKET\][\[$PS1_COLOR_LOW\]*\[$PS1_COLOR_BRACKET\]>\[$rst\] "'

Then choose a theme

PS1_Theme Kristian
PS1_Theme Hulk
PS1_Theme Bunny
PS1_Theme Princess
PS1_Theme Tux
PS1_Theme BnW
PS1_Theme Plain

Or use default set in /etc/promptrc

PS1_Render

Themes

To define a new theme named BlueSea, according to the colors used in the default prompt, you need to define a function like so :

function __PS1_Theme_Blue {
    PS1_COLOR_BRACKET=$BLUE
    PS1_COLOR_LOW=$blu
    PS1_COLOR_MEDIUM=$gre
    PS1_COLOR_HIGH=$GRE
    PS1_COLOR_ROOT=$RED
    PS1_COLOR_USER=$PS1_COLOR_LOW
    PS1_COLOR_HOST=$PS1_COLOR_LOW
    PS1_COLOR_PROMPT=$PS1_COLOR_HIGH
    PS1_BRACKET_OPEN="{"
    PS1_BRACKET_CLOSE="}"
    function PS1_Format_Widget {
        echo "\[$PS1_COLOR_BRACKET\]$PS1_BRACKET_OPEN\[$PS1_COLOR_HIGH\]$1\[$PS1_COLOR_BRACKET\]$PS1_BRACKET_CLOSE"
    }
}

This can be done globally in /etc/promptrc or per user in $HOME/.promptrc

Install

To install, copy promptmanager and promptrc to /etc and userpromptrc to "/etc/skel/".

Install system wide for new users.

sudo cp promptmanager promptrc /etc/
sudo cp userpromptrc /etc/skel/.promptrc

Instead of having it's own file in the skel, you add userpromptrc to "/etc/skel/.bashrc".
```
sudo bash -c 'cat userpromptrc >> /etc/skel/.bashrc'
```

You can also copy it to $HOME/.promptrc.

cp userpromptrc $HOME/.promptrc

Now you need to source /etc/promptmanager from /etc/profile and that depends on your distribution, but look at where it sets PS1 and replace that.
