Patch to v1.1.1. check_env could only reason at module granularity, so a var
that lives on one struct of a multi-struct module (e.g. EINHERJAR_SERVER_CORS_ORIGINS
on web.Config, not web/server.Config) couldn't be flagged dead when the app
composes the sibling struct. Adds struct-level selectors to close that gap.
internal/tools (check_env):
- New `composes` input: exact config structs as module/subpackage/Struct selectors
(e.g. web/server/Config, db-postgres/Config, core/logz/Config), alongside or
instead of the coarse `modules` list.
- not-composed now reasons over the union of composed vars (from modules AND
struct selectors), so it surfaces struct-level dead vars. Coarse modules:["web"]
keeps the prior behavior.
- parseStructSelector helper; errors on malformed or non-existent selectors.
Tests: struct-level dead-var catch (CORS flagged with web/server/Config but not
with module web), bad-selector errors; existing calls updated to the new arg.
Version bumped to v1.1.1 (badge + serverVersion). No dependency changes.
Minor to v1.1.0. Make the whole environment-variable surface derive from the
indexed component-config tags instead of a hand-maintained list that drifts.
Also folds in the scaffold-symbol fixes staged as v1.0.1 (never tagged); the
generated scaffold compiles clean against einherjar v1.0.0.
internal/envspec (new):
- Parse index struct tags into env vars {name, module, struct, field, required,
default}. One source of truth: ParseTag, ForModule, FindStruct, All, KnownNames.
internal/tools:
- get_config_env: list the real env vars a component config reads (or all).
- check_env: flag unknown EINHERJAR_* names, required vars missing for the
composed modules, and dead vars (set for an uncomposed module).
- get_scaffold: .env.example is now DERIVED from the index — required vars
uncommented with a dev value, defaulted vars commented with their default.
The scaffold now composes logz.Config (Log logz.Config) so EINHERJAR_LOG_*
are live and documented, not hardcoded/ignored (log format is env-driven).
- validate_snippet: inject the real env-var name set into the rules package.
internal/index/builtins (wire conventions):
- Route the incremental "compose a component later" flow to get_config_env /
check_env; distinguish framework EINHERJAR_* from app-owned APP_* (JWT).
- Compose logz.Config in the config + Run() examples, to match the scaffold.
internal/rules:
- config.unknown-env-var (twelfth rule): reject an env:"EINHERJAR_*" struct tag
the framework doesn't declare. No-op until the server injects the name set, so
it never fires on incomplete knowledge.
Fixed (was v1.0.1): scaffold health hook + wire builtin used logz.Logger (real:
contracts/logging.Logger) and postgres.Component (hooks take Provider); env tags
were EINHERJAR_SERVER_ADDR / EINHERJAR_PG_DATABASE (real: _HOST/_PORT / _PG_NAME).
Tests: envspec unit tests; env tools against the real data/index.json; the rule.
Verified by generating the scaffold, building it against local einherjar v1.0.0
(exit 0), and runtime-loading the composed logz.Config (EINHERJAR_LOG_LEVEL=DEBUG
-> slog.LevelDebug, EINHERJAR_LOG_JSON=true). Version bumped to v1.1.0 (badge +
serverVersion). No dependency changes.
