Table.Columns/Constraints/Indexes/Relationships are Go maps, and every
writer, reader, diff, inspector, and merge code path that iterated them
directly was subject to Go's randomized map order, so identical input
could produce different output (or a different in-report violation/diff
order) on every run. Most visibly this showed up as bun/gorm `unique:`
struct tags changing order across consecutive `make models` runs with no
source change.
Fixed by sorting map iteration (by Sequence then Name, or alphabetically
for string-keyed maps) everywhere the order affects generated output or
first-match tie-break logic, across the bun, gorm, sqlite, dbml, drawdb,
pgsql, prisma, graphql, typeorm, drizzle, and dctx writers; the dctx,
prisma, and typeorm readers; the shared models.GetPrimaryKey/
GetForeignKeys helpers; pkg/diff, pkg/inspector, and pkg/merge; and the
TUI column/relationship pickers in pkg/ui.
Bun's pgdialect scans/appends native slices directly, so array columns
(text[], integer[], uuid[], ...) always generate as plain []string,
[]int32, etc. with an explicit "array" bun tag, regardless of --types
(sqltypes/stdlib/baselib). The SqlXxxArray wrapper types are no longer
used for Bun array columns (gorm is unaffected and keeps using them).
Adds --array-nullable pointer_slice to represent nullable array columns
as *[]T instead of []T, so callers can distinguish SQL NULL (nil) from
'{}' (pointer to an empty slice). Verified end-to-end against a live
PostgreSQL instance for NULL/{}/populated arrays in every --types mode.
Closes#13
bun's pgdialect overrides Field.Scan/Append with its own slice-only array
handling whenever the tag's type: value ends in "[]", clobbering the
sql.Scanner/driver.Valuer implemented on SqlXxxArray wrapper types and
causing "bun: Scan(unsupported sqltypes.SqlStringArray)" at query time.
Emit the underscore-prefixed internal type name (e.g. _text) instead,
which is DDL-valid but doesn't end in "[]" so bun leaves our scanner alone.
* Implement tests for inserting, updating, and retrieving UUIDs in a SQLite database.
* Verify that Value() returns a string representation of the UUID.
* Ensure compatibility with custom types implementing fmt.Stringer.
* Update type mapper imports to reflect new package path.
* change default nullable type from resolvespec to baselib
* update type mappings in tests to reflect new nullable types
* adjust comments for clarity on nullable type options
* Implement SQLiteToCanonicalTypes for type mapping
* Add ConvertSQLiteToCanonical and ConvertCanonicalToSQLite functions
* Update mapDataType to utilize new conversion logic
* Introduced extractTypeParts function to handle embedded dimensions in type strings.
* Updated columnTypeConflict to utilize new type extraction logic.
* Improved PostgreSQL type normalization and handling in various components.
* Introduce ContinueOnError option to WriterOptions
* Update writer functions to support continue-on-error behavior
* Modify migration and database writing to handle continue-on-error
- Introduced equivalent base types and variants for PostgreSQL types to normalize type comparisons.
- Added functions for normalizing SQL types and retrieving equivalent type variants.
- Updated migration writer to handle type alterations with checks for existing types.
- Implemented logic to create necessary extensions (e.g., pg_trgm) based on schema requirements.
- Enhanced tests to cover new functionality for type normalization and migration handling.
- Improved handling of GIN indexes to use appropriate operator classes based on column types.
* Update BuildBunTag to append "array" for array types
* Add tests for handling array types in TypeMapper
* Adjust regex in SanitizeStructTagValue to preserve array suffix
* Fix pgsql reader double-quoting defaults: normalizePostgresDefault strips
surrounding SQL string literal quotes from column_default before storing,
matching the convention used by every other reader.
* Add NullableTypes field to WriterOptions with NullableTypeResolveSpec
(default) and NullableTypeStdlib constants.
* Both bun and gorm TypeMappers now accept a typeStyle parameter. stdlib
mode produces sql.NullString/NullInt32/NullTime etc. for nullable scalars,
plain Go slices for arrays, and time.Time for NOT NULL timestamps. Default
resolvespec behaviour is unchanged.
* Add --types flag to convert and split commands.
* Update bun/README.md and gorm/README.md with side-by-side generated code
examples, updated type mapping tables, and Writer Options documentation.
* Implement tests to ensure explicit type modifiers are preserved during conversion.
* Validate behavior for varchar, numeric, and custom vector types.
Bun and GORM struct tags now emit quoted defaults for string/date/time/UUID
columns (e.g. default:'disconnected') and unquoted defaults for numeric and
boolean columns (e.g. default:0, default:true). Function-call expressions
such as now() or gen_random_uuid() are never quoted regardless of type.
Adds QuoteDefaultValue(value, sqlType) helper in pkg/writers and updates
both type mappers and the bun writer tests accordingly.
