Journal Format

Tacklers journal is based on idea of plain text files, where each accounting record is written in human readable and editable form into those text files. This idea of text based double-entry accounting was invented and pioneered by John Wiegley in 2003.

Tackler Ain’t Calculator and Kernel for Ledger Equivalent Records.
Why not? Because it uses simplified syntax.

Journal files

Journal can be a single file or it can be split on transaction level into multiple files (shards). See general Journal Documentation, Transaction Data Sharding, Usage Manual and tackler.toml for further details how to define used storage system and ideas for different sharding schemes.
