A Python script that generates hledger compatible price directives for the Argentine “Blue Dollar” (black market exchange rate) based on the average between “buy” and “sell” prices listed by the Bluelytics API. The script was created to automate my own personal workflow, and so is rather rudimentary and lacks extensibility, but suggestions and improvements are welcome.
- Clone this repository:
git clone https://github.com/felipetappata/hledger-blue-rates.git
- Navigate to the project directory:
cd hledger-blue-rates
- Install the required dependencies:
pip install -r requirements.txt
Call from the terminal with the following command:
python get-blue-rates.py YYYY-MM-DD
Where YYYY-MM-DD is the date from which you want to start generating price directives.
The script will generate a file called blue-rates.journal containing price directives from the specified date to the current date.
The generated file can be included in your hledger journal file using the include directive:
!include blue-rates.journal
It assumes that amounts denominated in dollars are in the USD currency and amounts denominated in Argentine Pesos are in the ARS currency.
- Python 3.6 or later
