Readme

Use Jinja and data from Home Assistant to generate your README.md file with the list of all your installed add-ons and custom components

Installation

1. Download it with HACS
2. Restart Home Assistant
3. Choose:
   • Add readme: to your HA configuration.
   • In the HA UI go to "Configuration" -> "Integrations" click "+" and search for "Generate readme"

Using your HA configuration directory (folder) as a starting point you should now also have this:

custom_components/readme/.translations/en.json
custom_components/readme/__init__.py
custom_components/readme/config_flow.py
custom_components/readme/const.py
custom_components/readme/default.j2
custom_components/readme/manifest.json
custom_components/readme/services.yaml

Example configuration.yaml

readme:

Warning!

This integration will replace your files!:

• README.md
• ui-lovelace.yaml (if you enable convert_lovelace)

Configuration options

Usage

In the root of your configuration directory (folder) you will get a new directory (folder) called "templates" in that directory (folder) there will be a file called "README.j2" this is where you change the template that will be used for generation of the README.md file.

When you are happy with how the template look, run the service readme.generate in Home Assistant, this will generate the README.md file, and the ui-lovelace.yaml file if you enabled that.

Usable variables

In addition to all Jinja magic you can do, there is also some additional variables you can use in the templates.

• codeowners
• version

Example usage of the custom_components variable:

{%- set custom_component_descriptions = {"readme": "Generates this awesome readme file."} -%}
{% for integration in custom_components %}
### [{{integration.name}}]({{integration.documentation}})
{% if integration.domain in custom_component_descriptions %}
_{{custom_component_descriptions[integration.domain]}}_
{% endif -%}
{% endfor -%}

{%- macro sentence_case(text) -%}
	{{ text[0]|upper}}{{text[1:] }}
{%- endmacro -%}
{% set data = namespace(domains=[]) %}
{%- for state in states %}
{%- if (state.entity_id in alexa_configuration.entities.included) or (state.entity_id not in alexa_configuration.entities.included and state.domain in alexa_configuration.domains) %}
{%- if state.domain not in data.domains %}
{%- set data.domains = data.domains + [state.domain] %}
{%- endif %}
{%- endif %}
{%- endfor %}
{%- for domain in data.domains %}
