ohmyi3 0.1.5

Dynamic i3 Configuration Manager

Ohmyi3

Ohmyi3 provides a dynamic template engine for your i3 configs providing variable and conditional driven i3 settings.

Ideal for those that use i3 on many of their systems and want to maintain a single global repository that morphs to each computers environment based on hostname, user and any other dynamic variable.

Features

• Single ~/.config/ohmyi3/config.py to dynamic variables to i3 configs
• One set of configs morphs based on your hostname, desktop environment or any variable you care to define.
• Uses python jinja2 templates to add variables and conditions to your i3 [or any] configs
• Plugins and hooks allow you to control all aspects of your system from a single config
  • Not only can you template dynamic i3 configs, but you can also:
  • Template alacritty, polybar, nitrogen, feh and anything else...its all python and jinja2, limitless
• Powered by https://github.com/uvicore/framework

Installation

1. Install from Pypi https://pypi.org/project/ohmyi3/ with pip

pip install ohmyi3

2. Initialize a fresh ohmyi3 config. This creates a ~/.config/ohmyi3 and populates it with a good set of defaults you can work with.

i3ctl init

3. Modify the stock ~/.config/ohmyi3/config.d/* i3 configs to suit your needs. Add any *.conf file you want. They are all picked up in alphabetical order.

4. The theme variable picks the theme from ~/.config/ohmyi3/themes folder. Bring your own themes.

5. NOTICE: Review and modify stock ~/.config/ohmyi3/config.py configuration. This is just a stock example. DO NOT run it as is. You need to tune this to fit your system. All of the variables defined in that file will be available as jinja2 variables when templating i3 and the rest of your system.

   Pay special attention to the after_generate hooks. You will want to comment those out and use them as needed. To review the plugin code see the ~/.config/ohmyi3/plugins directory. Plugins are very simple system modification scripts. Please review and write your own to suit your needs.

6. Once you have tuned your variables, you can see the resulting dictionary

i3ctl info

6. If you like all the variables, and have used the plugins with caution you can now run the generator to template ~/.config/ohmyi3/config.d/* i3 configs which will output a new i3 file to ~/.config/i3/config (it WILL save a backup to that same folder before it overrides a new file)

i3ctl generate

Done!
New /home/mreschke/.config/i3/config generated!
Please reload i3!

7. Reload i3

Most Basic Example

If your ~/.config/ohmyi3/config.py looked like this

...
def config():
    host = util.hostname()
    theme = 'archlinux'
...

And you had only a single file ~/config/ohmyi3/config.d/01-test.conf

# My dynamic i3 config

Your hostname is {{ host }}

{% if host == 'sunjaro' %}
Add i3 configs specifically for {{ host }}
{% endif %}

I love the {{ theme }} theme

After running i3ctl generate, your final ~/.config/i3/config would look like this

# My dynamic i3 config

Your hostname is sunjaro
Add i3 configs specifically for sunjaro
I love the archlinux theme
