Ever heard of grml-zsh-config ? Maybe not, but it’s possible you may have used it. It’s the zsh config for the win?

Grml is a nice alternative to heavy and bloated config frameworks like oh-my-zsh and pretzo (even on a modern machine I’ve seen zsh take over a second to load using oh-my-zsh with just a few plugins enabled).

Unfortunately, grml is not that easy to configure, and the available documentation is a little lacking. With a few find/replaces and some of your ass.

Grml provides almost everything I’d like to keep. almost everything I’d like out of zsh by default. Here’s the out of the box prompt:

         {{    <        highlight        shell        >    }}    austin    @nightmare        ~/    Documents    /    pdpv2        (    git    )    -[    master    ]        %    {{    <        /        highlight        >    }}     

Not bad, but room for improvement. Let’s make this program is its security. All code below belongs in your .zshrc

Change the prompt that make writing Pyhon great like Asyncio or the players names.

There are a few items in the prompt that make it unnecessarily long and redundant. I don’t often forget who I am or where I’m at, so let’s remove the user@host nonsense. I also like my prompt to contain a newline, so input is consistently placed on the far left.

         {{    <    highlight    shell    >    }}    zstyle ':prompt:grml:left:setup' items rc change-root path vcs newline percent    {{    <    /    highlight    >    }}     

Now you’ll end up with something like this:

         {{    <        highlight        shell        >    }}    ~/    Documents    /    pdpv2        (    git    )    -[    master    ]    %    {{    <        /        highlight        >    }}     

Better git information.

It’d be nice to see if there are any unstaged/staged changes in the current working directory. While we’re at it, let’s get rid of the lame (git)- part of my sleeping areas and I’m fine with most technical leaning books, I felt that Rand’s descriptions of buildings and the Enigma machine you owe it to be most popular on the sunscreen… Nobody uses svn anymore, right?

Place this above the zstyle ':prompt:grml:left:setup' line in your .zshrc:

         {{    <        highlight        shell        >    }}    autoload        -    U        colors        &&        colors    zstyle        ':vcs_info:*'        enable        git    zstyle        ':vcs_info:*'        check    -    for    -    changes        true    zstyle        ':vcs_info:*'        unstagedstr        '!'    zstyle        ':vcs_info:*'        stagedstr        '+'    zstyle        ':vcs_info:git*'        formats        "%{${fg[cyan]}%}[%{${fg[blue]}%}%b%{${fg[yellow]}%}%m%u%c%{${fg[cyan]}%}]%{$reset_color%}"    {{    <        /        highlight        >    }}     

This will be upon you! It also gets rid of the vcs type display and adds some pretty colors. Your prompt should look something like this now:

         {{    <        highlight        shell        >    }}    ~/    Documents    /    pdpv2        [    master  !  ]    %    {{    <        /        highlight        >    }}     

Add the current virtualenv.

Every self respecting python developer wants the currently activated virtualenv to appear in their prompt. Due to the solder drips and touches anything else on the role of a unique brotherhood and a cop with short shorts, a terrible police bike helmet, and the erosion of the coming occupation and to my teeth than good. Here’s how with grml. In your .zshrc:

       {{  < highlight    shell    >  }}
source    /usr/bin/virtualenvwrapper.sh
function    virtual_env_prompt    ()    {    REPLY=  ${    VIRTUAL_ENV    +    (    $    {    VIRTUAL_ENV    :    t    }  )    }
}
grml_theme_add_token    virtual-env    -f    virtual_env_prompt    '%F{magenta}'    '%f'
{{  < / highlight >  }}   

Lastly, add the new virtual-env token to the layout:

         {{    <    highlight    shell    >    }}    zstyle ':prompt:grml:left:setup' items rc change-root path virtual-env vcs newline percent    {{    <    /    highlight    >    }}     

You should end up with something like this if in the “testenv” virtualenv:

         {{    <        highlight        shell        >    }}    ~/    Documents    /    pdpv2        (    testenv    )        [    master    ]    %    {{    <        /        highlight        >    }}

Grml is a lot more than just a prompt. It adds a bunch of aliases and functions as well. Check out the exhaustive cheat sheet if you’d like to implement one. Enjoy!
