i3nator

i3nator is Tmuxinator for the i3 window manager.

It allows you to manage what are called "projects", which are used to easily restore saved i3 layouts (see Layout saving in i3) and extending i3's base functionality by allowing you to automatically start applications too.

Installation

You have multiple options to install i3nator:

  1. If you have a recent Rust with Cargo installed, you can install i3nator directly from crates.io:

    $ cargo install i3nator
    
  2. Alternatively, you can download the supplied static binary from the release page, this should work without any additional dependencies.

  3. Another option is to install from directly from source (this again requires a recent Rust installation):

    $ git clone https://github.com/pitkley/i3nator.git
    $ cd i3nator
    $ cargo install
    

Note: If you want to be able to use the automatic command execution feature, you will need to install xdotool.

Usage

Following the usage of i3nator as of 1.1.0.

i3nator 1.2.0
Pit Kleyersburg <pitkley@googlemail.com>
i3nator is Tmuxinator for the i3 window manager

USAGE:
    i3nator <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    copy      Copy an existing project to a new project
    delete    Delete existing projects
    edit      Open an existing project in your editor
    help      Prints this message or the help of the given subcommand(s)
    info      Show information for the specified project
    layout    Manage layouts which can used in projects
    list      List all projects
    local     Run a project from a local TOML-file
    new       Create a new project and open it in your editor
    rename    Rename a project
    start     Start a project according to it's configuration
    verify    Verify the configuration of the existing projects

Every command -- except layout -- is for managing your projects, i.e. creating, editing, starting and potentially deleting them.

layout is a bit special, because it is most of the commands used for projects, except for i3 layouts:

i3nator-layout 1.2.0
Manage layouts which can used in projects

USAGE:
    i3nator layout <SUBCOMMAND>

FLAGS:
    -h, --help    Prints help information

SUBCOMMANDS:
    copy      Copy an existing layout to a new layout
    delete    Delete existing layouts
    edit      Open an existing layout in your editor
    help      Prints this message or the help of the given subcommand(s)
    info      Show information for the specified layout
    list      List all layouts
    new       Create a new layout and open it in your editor
    rename    Rename a layout

These commands allow you to manage i3 layouts in addition to the actual projects which will be able to use and reuse them.

Examples

(See here for additional examples. See also the types::Config API documentation for detailed documentation on the configuration parameters.)

Full workflow

  1. Open all applications you want and lay them out on a workspace as desired.

  2. Save the workspace's layout using i3-save-tree, feeding the layout directly into i3nator's layout management:

    $ i3-save-tree --workspace 1 | i3nator layout new -t - mylayout
    

    If you don't want the layout managed by i3nator, you can alternatively:

    • copy the layout to your clipboard, and insert it directly in your project configuration later or
    • save it to a file on your disk, and reference this file-path in your configuration later.

    If you are using i3nator's layout management, the above command should drop you into an editor, ready for step 3.

  3. Modify the saved layout to accurately match created applications. See Editing layout files on how to do this.

    If you copied the layout to your clipboard, you will be able to do this in step 5.

  4. Create a new project:

    $ i3nator new myproject
    Created project 'myproject'
    Opening your editor to edit 'myproject'
    

    This will open your default editor with a configuration template. If it doesn't, you have to specify either the $VISUAL or the $EDITOR environment variable.

    You can also simply edit the configuration file directly. Use i3nator info <PROJECT> to retreive its path.

  5. Modify the template to fit your needs. This includes:

    1. Setting the main working directory.

    2. Setting the destination workspace (this is optional, if not specified, the active one will be used).

    3. Specifying which layout to use. If you have passed the layout to i3nator in step 2, you can simply enter its name here, which in case two was mylayout.

      Alternatively you can either supply a path to the file containing the layout, or you can paste the layout from step 2 directly into your project file as a multi-line string. At this point you will also be able to modify the layout to match applications correctly.

    4. Configuring which applications to start and how to start them. This is done by setting the command to the full command to be used to start the application and optionally configuring a different working directory if desired.

      If you want to execute additional commands or keypresses in the started applications, you can also define exec.

    The resulting configuration could look something like this:

    [general]
    working_directory = "/path/to/my/working/directory"
    workspace = "1"
    layout = "mylayout"
    
    [[applications]]
    command = "mycommand --with 'multiple args'"
    exec = ["command one", "command two"]
    
  6. Save and close your editor. This will automatically verify the created configuration. If there is an issue it will tell you what failed and allow you to reedit the file directly or ignore the error and exit.

With these prerequisites fulfilled, you are now able to start a configuration which appends your layout to a specified workspace and starts the configured applications:

$ i3nator start myproject
