basalt 0.0.3

A type-safe, migration-first ORM for Dart: a compile-time-checked query builder, code-generated row mappers, and pluggable SQL backends.

Changelog

0.0.3

Shared DevTools inspector client — one host + client + DTO layer behind the ext.basalt.* protocol, so the DevTools extension and the basalt_mcp server stop re-implementing it.

• New package:basalt/devtools_client.dart entrypoint (kept separate from the host package:basalt/devtools.dart): a transport-agnostic InspectorClient plus an InspectorTransport seam and the shared DTOs. Consumers implement only the transport (VM service, DevTools serviceManager, ...).
• BasaltExtension — enum of the ext.basalt.* method names, the single source of truth for host registration and every client (exported from both entrypoints).
• DTO fromJson factories now parse real jsonDecode output (previously the blind as List<...> casts threw); SqlResultDto.fromJson restores truncated; RegisteredInstance.fromJson added.
• Breaking (dev-only): RegisteredInstance.backend removed — the inspector no longer infers a backend name. InspectorService now takes placeholders, identifier quoting, and value encoding from Connection.dialect (this also fixes DateTime encoding on the raw-SQL path). lib/src/devtools/ was reorganized into protocol/ · dto/ · host/ · client/ (internal), and InspectorService was split into focused collaborators.

0.0.2

Single-statement batch writes.

• updateAll(table).keyedBy(col).values([...]) — a new UpdateAllStatement that updates many rows with per-row values in one statement (WITH ... AS (VALUES ...) UPDATE ... FROM), with composite keys (repeated keyedBy), an optional extra .where(...), and RETURNING support (columns are table-qualified there to stay unambiguous next to the VALUES table).
• SqlDialect.castType(SqlType) — new dialect seam naming the native type to CAST a bound parameter to where SQL gives the server no inference context (the VALUES table of updateAll); dialects that don't need casts return null.
• ColumnValue now carries the column's SqlType (set by TableColumn.set) so serialization can emit those casts.
• A zero-row INSERT (no .value(...)/.values(...)) now throws StateError at build time instead of emitting invalid SQL.
• @Insertable doc updated for the new generated batch extension (see basalt_codegen 0.0.2).

0.0.1

Initial development release of the basalt_dart core.

• Type system: SqlType<T> codecs (IntSqlType/StringSqlType/DoubleSqlType/BooleanSqlType/ BlobSqlType/DateTimeSqlType) with a single NullableSqlType(...) wrapper for nullable columns.
• Schema: sealed TableColumn<T, Tbl> (ValueColumn / PrimaryKey / Ref), TableRef, QuerySource, TableAlias for self-joins.
• Expressions with phantom table scope; eq/ne/gt/ge/lt/le/isIn/between/isNull/like/ eqColumn, operator sugar, and &/| combinators.
• Query builder: from().where().orderBy().limit().offset().select().innerJoin()/leftJoin().map() → MappedQuery; RowReader (read by column name) and reusable RowMapper.
• Writes: insertInto / update / deleteFrom with TableColumn.set.
• Serializer (QueryBuilder + SqlDialect) with two-tier join scope validation.
• Async-first Connection interface with transactions (nested → SAVEPOINT) and introspect().
• Annotations for codegen: @Queryable, @Insertable, @AsChangeset, @Column (readOnly/writeOnly), @Relation.
