Instance Method Details

#camelize(basename, _abspath) ⇒ Object

Very basic snake case -> camel case conversion.

inflector = Zeitwerk::Inflector.new
inflector.camelize("post", ...)             # => "Post"
inflector.camelize("users_controller", ...) # => "UsersController"
inflector.camelize("api", ...)              # => "Api"

Takes into account hard-coded mappings configured with ‘inflect`.

Configures hard-coded inflections:

inflector = Zeitwerk::Inflector.new
inflector.inflect(
  "html_parser"   => "HTMLParser",
  "mysql_adapter" => "MySQLAdapter"
)

inflector.camelize("html_parser", abspath)      # => "HTMLParser"
inflector.camelize("mysql_adapter", abspath)    # => "MySQLAdapter"
inflector.camelize("users_controller", abspath) # => "UsersController"
