Introduce additional casing strategies.

[fr33r]

Description

These changes introduce support for the following column casing strategies:

• screaming snake case (EXAMPLE_COLUMN_NAME)
• uppercase (EXAMPLECOLUMNNAME)
• lowercase (examplecolumnname)

It additionally supports screaming snake case for table names.

NOTE: it's important to use the same specified casing when using the WithPrimaryKeyColumn or WithPrimaryKeyColumns options.

Rationale

While less common, these casing strategies for columns and tables do occur.

Suggested Version

v1.2.0

Example Usage

obj = ...

// uppercase column names.
options := []morph.ReflectOptions{
  morph.WithInferredColumnNames(morph.UpperCaseStrategy),
  moprh.WithPrimaryKeyColumn("ID"),
}
table, err := morph.Reflect(obj, options...)
if err != nil {
  panic(err)
}

// lowercase column names.
options := []morph.ReflectOptions{
  morph.WithInferredColumnNames(morph.LowerCaseStrategy),
  moprh.WithPrimaryKeyColumn("id"),
}
table, err := morph.Reflect(obj, options...)
if err != nil {
  panic(err)
}

// screaming snake case column names.
options := []morph.ReflectOptions{
  morph.WithInferredColumnNames(morph.ScreamingSnakeCaseStrategy),
  moprh.WithPrimaryKeyColumn("ID"),
}
table, err := morph.Reflect(obj, options...)
if err != nil {
  panic(err)
}
