Add the Cobra-based command surface and the flag/env/config-file
resolution layer that all commands share.
Configuration (internal/config):
- Load() resolves settings with the documented precedence flags > env >
config file > defaults, via viper: GITFLOW_-prefixed env vars with
dot-to-underscore mapping, plus ~/.gitflow.yaml (or $GITFLOW_CONFIG)
- RegisterFlags/NewFlagSet own the flag definitions so every command and
the tests share a single source of truth
- Config/Validate/Dump cover dir, interval, format (table/json/compact),
exclude globs, max depth, worker count, and the AI block (enabled,
provider, model, api_key_env, base_url); ConfigFile records the loaded
path; Dump renders the effective config as human-readable YAML with the
interval as a duration string
App orchestration (internal/app):
- New() validates the configuration at the boundary (fail fast)
- ScanOnce() runs discovery then a concurrent status scan, warning on
stderr and continuing when discovery is only partially successful
(e.g. permission-denied subtrees), and bundles everything into a
ScanResult
CLI (cmd/gitflow):
- root command with scan / config / version subcommands
- scan: resolves config, prompts for the parent directory when stdin is a
TTY and --dir was not given (per the README), runs a single pass, and
renders the result — interim plain/JSON output until phase 3 lands the
presenter package
- config: prints the effective configuration
- version: prints the build version (ldflags-injectable)
- signalContext() wires SIGINT/SIGTERM into a cancellable context for
graceful shutdown
Testing:
- config: defaults, flag overrides, env overrides, flag-beats-env
precedence, config file loading (including duration and slice values),
GITFLOW_CONFIG path override, validation failures, and Dump output
- app: config validation on New, end-to-end ScanOnce over a real temp
repo, and missing-directory errors
Verified: go build, go vet, go test -race, gofmt clean; manual smoke of
`gitflow version`, `gitflow config`, and `gitflow scan -d <dir>` against a
scratch directory with a dirty repo.
