Itermocil Save

Introduction

iTermocil allows you to setup pre-configured layouts of windows and panes in iTerm2, having each open in a specified directory and execute specified commands. You do this by writing YAML files to save your layouts. If you're using session restoration or saved window layouts in iTerm, you should find iTermocil is a nice upgrade on that.

iTermocil supports iTerm 2.x and the new 3.x (including later betas). It works better with the new 3.x versions which have improved Applescript support.

Installing iTermocil

# Install `itermocil` via Homebrew
$ brew update
$ brew install TomAnthony/brews/itermocil

# Create your layout directory
$ mkdir ~/.itermocil

# Edit ~/.itermocil/sample.yml (look for sample layouts in this very `README.md`)
# There are also a variety of example files in 'test_layouts' directory in this repo
$ itermocil --edit sample

# Run your newly-created sample layout
$ itermocil sample

# Note that you can also used ~/.teamocil as your directory, if you're a teamocil user.

Using iTermocil

$ itermocil [options] <layout-name>

Alternatively, if you have an iTermocil.yml file in the current directory you can simply run itermocil and it will use that file, so you can have files inside your projects and sync via Github etc:

$ cd my_project
$ itermocil

iTermocil is compatible with all of teamocil's flags, and they all work in the same way.

Session

Windows

Panes

A pane can either be a String or a Hash. If it’s a String, Teamocil will treat it as a single-command pane.

Examples

See some example of various layouts below, or see Layouts for more information on the available layouts. There is also a variety of example layout files in this repo.

Simple two pane window

windows:
  - name: sample-two-panes
    root: ~/Code/sample/www
    layout: even-horizontal
    panes:
      - git status
      - rails server

|                  |                  |
|                  |                  |

Simple three pane window

windows:
  - name: sample-three-panes
    root: ~/Code/sample/www
    layout: main-vertical
    panes:
      - vim
      - commands:
        - git pull
        - git status
        name: 'git'
      - rails server

Note: the 'name' directive in 'commands' in an iTermocil specific addition, which will cause teamocil to fail if it tries to parse the file.

Additional Layouts

In the Layouts file you can see these additional layouts:

• 3_columns - 3 columns with as many rows as needed
• double-main-vertical - 2 left full height columns, and a third multi-row column
• double-main-horizontal - 2 rows, where bottom row is 2 full width columns, and top row is multi-column

teamocil

iTermocil was originally inspired by and is compatible with teamocil, allowing anyone with teamocil files to execute those files natively in iTerm2, without needing tmux or any other dependency. However, iTermocil also has support for additional directives which will cause teamocil to fail, if used.

Notes

Teamocil allows supplying a name for a tmux session which has no purpose in iTerm, and so that option is ignored.

In tmux it is 'windows' that have names, whereas in iTerm each pane in a window can have a name. iTermocil will name all the child panes of a window by the window name given in a termocil file.

iTermocil works for iTerm 2+, but the script support is better in iTerm 2.9 beta so things run a bit faster/cleaner with iTerm 2.9+. If using beta builds you should grab the latest nightly, as the 2.9.20150626 'recommended beta' build does not have the required script hooks for iTermocil to work (and I have no plans to kludge something just for an incomplete beta that will never be released).

Starting with version 1.0.0, iTermocil uses Python3. If you need iTermocil for Python2, please use 0.2.1.

Shell autocompletion

Zsh autocompletion

To get autocompletion when typing itermocil <Tab> in a zsh session, add this line to your ~/.zshrc file:

compctl -g '~/.itermocil/*(:t:r)' itermocil

Bash autocompletion

To get autocompletion when typing itermocil <Tab> in a bash session, add this line to your ~/.bashrc file:

complete -W "$(itermocil --list)" itermocil

fish autocompletion

To get autocompletion when typing itermocil <Tab> in a fish session, add this line to your ~/.config/fish/config.fish file:

complete -c itermocil -a "(itermocil --list)"

A huge thanks to Rémi Prévost who authored teamocil, which inspired iTermocil. It is a fantastic tool, and I'm hoping that iTermocil helps more people discover teamocil.

To Do

• make a way to 'save' the current layout (not sure is possible)
• add tmuxinator file support
• add support for bespoke file format to support things like iTerm badges and tab colours
• possibly add a flag for using windows instead of tabs for new 'windows'
• pane 'focus' is supported, but window 'focus' is not yet - I'm not sure how to focus on a certain window still
• with the --edit flag, if no $EDITOR is set and a new layout name is given, then an empty file is created to be opened in a GUI editor. Is there a better way to handle this? Maybe clean up blank files whenever itermocil is launched?
