i3-jinja-config

Create an i3 config from Jinja2 template.

Why?

I am managing multiple computers and my configuration depends on screen/display keyboard etc... ... depend on hostname.

Jinja2 temlate allows me to use conditions and to include configs into config.

Inspiration

How it Work

The jinja-create-config.py script take all files withs .j2 suffix and render them to file named without .j2.

For example:

• config.j2 --> config
• py3status.conf.j2 --> py3status.conf

Usege

Save the jinja-create-config.py in your ~/.i3 directory and save your configuration into ~/.i3/config.j2 instead ~/.i3/config.

... in your ~/.xinitrc or ~/.Xsession

#create i3 config
~/.i3/jinja-create-config.py

#start i3
exec i3

... in your i3 configuration ~/.i3/config.j2

{%- if hostname == 'foo' %}
  set $primary DVI-I-1
  set $secondary VGA-1

  set $STATUS_FONT pango:Terminus 15
  set $STATUS_CONFFILE ~/.i3/i3blocks_foo.conf
{%- else %}
  set $primary DVI-1
  set $secondary VGA-0

  set $STATUS_FONT pango:Terminus 22
  set $STATUS_CONFFILE ~/.i3/i3blocks_bar.conf
{%- endif %}

# ...

bar {
    status_command i3blocks -c $STATUS_CONFFILE
    font $STATUS_FONT
    output $primary
    position top
    tray_output primary
}

... call jinja-create-config.py by reload and restart.

# Yes really is necessary use i3-msg
# reload the configuration file
bindsym $mod+Shift+c exec "~/.i3/jinja-create-config.py; i3-msg reload"
# restart i3 inplace (preserves your layout/session, can be used to upgrade i3)
bindsym $mod+Shift+r exec "~/.i3/jinja-create-config.py; i3-msg restart"

If you want split the configuration into multiple files:

# Floating windows
{% include 'floating.j2' %}

Use the force of Jinja templating language.
