From c8c07af9a151908b9978b9151da512a6411e9541 Mon Sep 17 00:00:00 2001 From: Jacob Kiers Date: Sat, 22 Nov 2025 16:23:53 +0000 Subject: [PATCH] feat: refactor CLI to subcommands and add dynamic adapter discovery Introduce structured subcommand architecture for better CLI organization and extensibility. Implement dynamic adapter discovery and validation system in core module for pluggable sources and destinations. Extract client initialization logic into dedicated CLI setup module for cleaner separation of concerns. Update README documentation to reflect new CLI structure and available commands. Add comprehensive tests for adapter validation and discovery functionality. Maintain backward compatibility for existing sync command usage. --- README.md | 27 ++++- banks2ff/src/cli/mod.rs | 1 + banks2ff/src/cli/setup.rs | 54 +++++++++ banks2ff/src/core/adapters.rs | 70 +++++++++++ banks2ff/src/core/mod.rs | 1 + banks2ff/src/main.rs | 180 ++++++++++++++++++++-------- specs/cli-refactor-plan.md | 216 ++++++++++++++++++++++++++++++++++ 7 files changed, 494 insertions(+), 55 deletions(-) create mode 100644 banks2ff/src/cli/mod.rs create mode 100644 banks2ff/src/cli/setup.rs create mode 100644 banks2ff/src/core/adapters.rs create mode 100644 specs/cli-refactor-plan.md diff --git a/README.md b/README.md index 46a0e28..1d1f15a 100644 --- a/README.md +++ b/README.md @@ -1,6 +1,6 @@ # Banks2FF -A robust command-line tool to synchronize bank transactions from GoCardless (formerly Nordigen) to Firefly III. +A robust command-line tool to synchronize bank transactions between various sources and destinations.
