Introducing Toml Bombadil v3

If you don't know what Toml Bombadil is you might want to read the introduction and quick start guide.

For those who used the previous version, here are the key feature coming with this version.

Features

Toml Bombadil now uses the tera engine for a full-featured templating experience.

tera is inspired by Jinja and thereby also uses the well-known {{ }} syntax for variable substitution and {% %} for logical expressions.

You're now able to write dotfiles with proper in-file templating logic. For instance, you can now write configs like this:

...
[[block]]
block = "hueshift"
step = 50
hue_shifter = "redshift"

{% if profile == "laptop" %}
# Only include the battery status in the laptop config.
[[block]]
block = "battery"
device = "BAT0"
driver = "sysfs"
format = "Bat0: {percentage}% {time}"
{% endif %}

[[block]]
block = "sound"
step_width = 2
...

Read the tera documentation to get a better understanding of what's now possible.

Breaking changes

The old templating syntax __[]__ doesn't work any longer. We know that this is a huge breaking change, but we assumed that this'll be a net positive for the project in the long run.
