blossom-hub/blossom

Blossom is a cross-platform command-line tool for double-entry plain text accounting, specifically designed to handle complex trading strategies, options, futures, and multi-currency assets. It provides a core engine that processes financial journals, calculates capital gains using FIFO matching, and tracks unrealized PnL for mark-to-market instruments. The system offers an interactive REPL, a built-in web server for data exposure, and utilities to convert journals to other formats like Beancount or Knut.

Blossom CLI version 0.52 is now available, introducing a full interactive REPL for journal management (load, switch, close, reload) and querying (balances, journal entries, balance series, lot analysis, holdings, meta data). The CLI adds a built-in web server (via Suave) to expose journal data over HTTP, and a new \pp\ command to convert Blossom journals to Beancount or Knut formats. Global options such as performance reporting, debug mode, load tracing, valuation date, and max rows are now configurable via the \set\ command.

blossom-cli · high confidence

This change introduces the Blossom project, a cross-platform command-line tool for double-entry plain text accounting designed specifically for traders. The repository establishes the core solution structure with three projects: \blossom-core\ for the accounting engine, \blossom-cli\ for the command-line interface, and \blossom-tests\ for verification. The application is built using F\# and .NET Core, supporting Windows and Linux, and focuses on handling complex trading strategies, options, futures, and multi-currency assets beyond standard personal finance tools. The release includes initial documentation, an MIT license, and a \.gitignore\ configuration for Visual Studio and Ionide development environments.

This change adds the foundational components for processing financial journals and analyzing investment performance. It introduces a new parser (JournalParser) to ingest journal data into an intermediate format, and a core analysis module (Analysis) that calculates capital gains using FIFO matching, tracks open/closed trading lots, and computes unrealized PnL for mark-to-market (MTM) instruments. The engine automatically generates accounting entries for trade settlements, dividend income, and periodic unrealized gains/losses, routing them to specific internal accounts (e.g., \_CapitalGains, \_UnrealisedGains). Additionally, it provides reporting capabilities (Reports) to display balances, journal entries, and statistics, along with helper modules for account manipulation and tabular output rendering.

blossom-core · high confidence

Added test data files for market, trading, and ledger scenarios; Initial test suite for infrastructure, parser, and journal logic.

The project has been upgraded to target .NET 10.0 (net10.0) and updated to use FSharp.Core version 10.0.102. This change affects the CLI, core library, and test projects, ensuring compatibility with the latest .NET runtime and F\# language features. Dependencies such as Suave (3.2.3) and FParsec (1.1.1) are also aligned with this new framework version.
