We made a CLI for using Costflow Syntax in your terminal. With Costflow CLI, you can create postings easily, and the output will be saved to your ledger file directly (only Beancount format is supported at the moment). Costflow CLI is completely running offline (except for $ and price command).
Install
npm install -g costflow-cliUsage
