# Action-carbon-emission-calculator-Demo # Carbon Emission Calculator AllSpice Actions Demo
This is repository with an Altium-based design for demonstrating the "Carbon Emission Calculator" AllSpice Actions add-on.
A repository for demonstrating the "Carbon Emission Calculator" AllSpice Actions add-on. This action uses the [generate-bom](https://hub.allspice.io/Actions/generate-bom) and [carbon-emission-calculator](https://hub.allspice.io/Actions/carbon-emission-calculator) Actions add-ons publically available in the [AllSpice Hub Actions](https://hub.allspice.io/Actions) organization.
As shown and explained below in the YML workflow file, the generate-bom add-on is used to generate a BOM using the py-allspice BOM generation utility function, and the carbon-emission-calculator add-on is used to obtain mock carbon emission data for the Archimajor 3D printer BOM components from a repository-based data source.
## Usage
### Step 1) Modify emission data ingestion in the add-on to your need:
The carbon-emission-calculator add-on uses a standalone data source CSV file with mock emissions figures for each component in the Archimajor 3D printer PCBA BOM. For your specific use, you will need to provide a data source and modify the data ingestion or query from source to match your needs:
#### For CSV-based data sources:
Replace your data source URL with the mock data URL in the add-on. The file format assumes part number as the 1st column, and the emission figure as the second column:
```
ALLSPICE_DEMO_CARBON_EMISSION_DATA_URL = "https://hub.allspice.io/AllSpice-Demos/Demo-Data-Source/raw/branch/main/Carbon-Emissions-Figures-Archimajor/archimajor-carbon-emissions-figures.csv"
```
#### For Database-based data sources:
If your emissions data is stored in a database, you will need a service to present that data via a queryable API endpoint. A rudimentary example of querying an API endpoint for emissions data is shown below:
```
ALLSPICE_DEMO_CARBON_EMISSION_DATA_API_URL_BASE = "https://your.site"
ALLSPICE_DEMO_CARBON_EMISSION_DATA_PART_SEARCH_ENDPOINT = ALLSPICE_DEMO_CARBON_EMISSION_DATA_API_URL_BASE + "/get_emission_figure/"
################################################################################
def query_demo_carbon_emission_data_for_mfr_part_number(url):
# Post the request and get the response
response = requests.get(url)
# Populate the search result return value
part_search_response = response.text
# Return response status code and search result
return (response.status_code, part_search_response)
```
### Step 2) Add the following step to your actions:
```yaml
# AllSpice running carbon emission calculator demo workflow
# Action triggers on push and issues
# Action runs "carbon-emission-calculator" action
# .allspice/workflows/Carbon-Emission-Calculator.yml
name: Generate Carbon Emission Figure for PCBA

# The path to the project file in your repo (.PrjPcb for Altium, .DSN for OrCad).
source_path: Archimajor.PrjPcb
# [optional] A path to a JSON file mapping columns to the component attributes
# they are from. This file must be provided.

# Default: 'bom.csv'
output_file_name: bom.csv
# [optional] A comma-separated list of columns to group the BOM by. If empty
# or not present, the BOM will be flat.
# Default: ''
group_by: "Part Number"
# [optional] The variant of the project to generate the BOM for. If empty
# or not present, the BOM will be generated for the default variant.
# Default: ''
