Add parseable `@<namespace>[(<target>)]: <args>` directives embedded in DBML.
They are stored losslessly on each object's Metadata, round-trip unchanged
through the DBML writer, and are translated to SQL only by the writer for the
matching dialect.
- models: Directive type + catalog; Metadata map added to Column and Index
- dbml reader: parse and attach directives at database/table/column/index
level; line-numbered errors; repeatable by default with singleton duplicate
detection. Fixes a preexisting bug where an `indexes {}` closing brace ended
the table early, dropping trailing Note: and directive lines.
- dbml writer: re-emit directives at their location; idempotent output
- pgsql writer: PARTITION BY / INHERITS / WITH / TABLESPACE (table),
STORAGE / COMPRESSION / identity (column), WITH / TABLESPACE (index)
- sqlite writer: WITHOUT ROWID / STRICT (table), COLLATE (column)
- --strict-directives flag on ReaderOptions and WriterOptions
- docs/DBML_DIRECTIVES.md + reader/writer READMEs

Merge conflict detection compared bigserial (DBML) against bigint (live
PostgreSQL read of an existing serial column) as incompatible types, since
serial is sugar over an integer column plus a sequence default and
PostgreSQL always reports back the underlying integer type. Add
SerialUnderlyingType and use it when comparing column types for conflicts.
QuoteDefaultValue also wrapped bare keyword expressions like CURRENT_DATE
in string quotes because they contain no parentheses, unlike function-call
defaults such as now(). Recognize known bare keyword defaults and leave
them unquoted across CREATE TABLE, ALTER TABLE ADD COLUMN, and
ALTER COLUMN SET DEFAULT generation.
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
* 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
* Introduce ContinueOnError option to WriterOptions
* Update writer functions to support continue-on-error behavior
* Modify migration and database writing to handle continue-on-error
* 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.
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.
* Introduce `--flatten-schema` flag to convert, merge, and split commands.
* Modify database writing functions to support flattened schema names.
* Update template functions to handle schema.table naming convention.
* Enhance PostgreSQL writer to utilize flattened schema in generated SQL.
* Update tests to ensure compatibility with new flattening feature.
* Dependencies updated for improved functionality.
* Implement SanitizeStructTagValue function to clean identifiers for struct tags.
* Update model data generation to use sanitized column names.
* Ensure safe handling of backticks in column names and types across writers.
* Implement SanitizeFilename function to clean identifiers
* Remove quotes, comments, and invalid characters from filenames
* Update filename generation in writers to use sanitized names
