## [Unreleased]
|
|
|
|
## [0.2.0] - 2026-05-02
|
|
|
|
### Added
|
|
|
|
- Module rename to `github.com/eslider/go-config` with subpackages `env`, `yaml`, `json`, `ini`.
|
|
- Uniform `Codec` API: `New`, `Map`, `Unmarshal`, `UnmarshalContext`, `Marshal`, `WriteTo`.
|
|
- `internal/source` for bytes, readers, files, and HTTP(S) URLs with optional headers and custom `http.Client`.
|
|
- `internal/keymap` recursive key walk with default `LowerAlnum` normalizer.
|
|
- `internal/merge` deep merge: recursive maps, last-write-wins scalars, configurable slice replace vs concat.
|
|
- `internal/structconv` around `github.com/go-viper/mapstructure/v2`.
|
|
- CLI `envc` (`cmd/envc`): `convert`, `get`, `merge`.
|
|
- Fixtures under `fixtures/` for identity, merge, edge, and invalid parser cases.
|
|
- `testfixtures` helper for tests.
|
|
- Repo-local ASRs in `docs/asr/`.
|
|
|
|
### Changed
|
|
|
|
- **Breaking:** the v0.1.0 `github.com/eslider/go-env` API (`Unmarshal`, `UnmarshalPrefix`, `AsMap`, …) is not re-exported; use `env.New(...).Unmarshal(...)`.
|
|
|
|
### Dependencies
|
|
|
|
- `github.com/go-viper/mapstructure/v2`, `github.com/joho/godotenv`, `gopkg.in/yaml.v3`, `gopkg.in/ini.v1`.
|
|
|
|
## [0.1.0] - 2026-04-24
|
|
|
|
Initial release as `github.com/eslider/go-env`. Extracted from `produktor.io/ai-fabric/pkg/env` per
|
|
`inventar/docs/asr/ASR-0008-ai-fabric-audit.md`.
|
|
|
|
### Added
|
|
|
|
- `Unmarshal(dst, opts...)` — decode all process env vars into a Go struct.
|
|
- `UnmarshalPrefix(dst, prefix, opts...)` — prefix-scoped variant that
|
|
strips the prefix before building the path.
|
|
- `AsMap()` / `AsMapPrefix(prefix)` — escape hatch returning the nested
|
|
`map[string]any` built from `os.Environ()`.
|
|
- Options: `WithTrim`, `WithWeaklyTyped`, `WithTagName`, `WithDecodeHook`.
|
|
- TrimSpace on string values is enabled by default; disable with
|
|
`WithTrim(false)`.
|
|
- Error wrapping with `%w` on both decoder configuration and decode
|
|
failures — matches `markets-platform/TP-general-code/pkg/system`
|
|
behaviour, improves on the original ai-fabric version.
|
|
|
|
### Tests
|
|
|
|
- 15 pure-Go unit tests. No mocks. `asMapFromEnviron` is tested with
|
|
synthetic `environ` slices (not a mock — a pure input). Follows the
|
|
eSlider `go-*` no-synthetic-mocks policy.
