Minor release. The indexer named composite types but could not describe
their shape: every declaration was truncated at the first brace, so a
struct symbol carried only its `type X struct` header and an interface
symbol only its `type X interface` header. Field names, field types, and
— most painfully — struct tags such as `env:"EINHERJAR_PG_HOST"` were
dropped, as were the method sets of every port interface. An assistant
could be told that `db-postgres` has a `Config` and a `Provider`, but not
what env vars configure the one or what methods the other requires. This
change captures both.
internal/index (schema):
- Symbol gains two optional fields. `fields` ([]Field) carries a struct's
field set — name, type, raw struct tag (surrounding backticks stripped),
doc comment, and an `embedded` marker. `methods` ([]Method) carries an
interface's method set — name, signature without the leading `func`, and
doc comment, including embedded interfaces. Both are omitempty and absent
for every other kind.
- SchemaVersion is deliberately unchanged. The two additions are additive
and omitempty, so an older consumer parses the new index unchanged; per
the existing rule the constant only bumps on a breaking format change.
internal/index (builder):
- collectSymbols now inspects each type's TypeSpec and, for a *ast.StructType
or *ast.InterfaceType, fills the new Symbol members. A grouped field
declaration (`x, y int`) yields one Field per name; an embedded field or
interface yields an entry with an empty name.
- New helpers: typeSpecType (underlying type expr of a lone type spec),
extractFields, extractIfaceMethods, fieldDoc (doc comment or trailing
line comment), and nodeString — a non-truncating printer used for field
types, tags, and method signatures, distinct from formatNode which keeps
truncating to produce the one-line header.
internal/index (search):
- matches() now also tests the query against struct field names, field
types, and struct tags, and against interface method names and
signatures. A query like an env-var key or a method name now resolves to
the type that declares it.
internal/tools:
- get_symbol and search_symbols descriptions updated to advertise the new
struct-field and interface-method coverage. No input/output schema change
beyond the additive Symbol fields, which get_symbol already returns whole.
internal/index (tests):
- New builder_test.go — the package previously had no tests. Builds a
temporary module fixture and asserts capture of struct fields (with tags
and docs), embedded fields, interface methods (with signatures and docs),
embedded interfaces, and discovery of a struct by one of its struct tags
(the failure mode that motivated the change).
Docs:
- CHANGELOG.md gains an [Unreleased] entry; README.md tool table updated to
state that get_symbol returns struct fields and interface methods and
that search_symbols matches fields, tags, and methods.
No new dependencies. The committed data/index.json placeholder is untouched
— the index is regenerated at image build (Dockerfile runs cmd/indexer),
so a deployment must be rebuilt to serve the richer index; a server still
running the prior image keeps serving the older, member-less one.
