struct Bindgen::Crystal::Format

Overview

Formatter for Crystal style code.

#argument(arg : Call::Argument, idx, expose_default = true, binding = false) : String
Formats arg as type name.
#argument_list(arguments : Enumerable(Call::Argument), binding = false) : String
Formats arguments as type name, ....
#floating_type?(type_name) : Bool
Returns true if type_name is a Crystal floating-type.
#literal(type_name, value) : String | Nil
Generates a literal value suitable for Crystal code, using the value of type_name.
#number_literal(type_name, value) : String | Nil
Returns the number literal of type_name with value.
#number_literal_suffix(type_name) : String | Nil
Returns the literal-suffix for Crystal code, to signify a literal matching the intended type_name.
#qualified_enum_name(type : Parser::Type, value : Int) : String | Nil
Returns the qualified name of value in the enum called enum_name.

def argument(arg : Call::Argument, idx, expose_default = true, binding = false) : String #

Formats arg as type name. If binding is true, treat this as argument for a fun declaration.

def argument_list(arguments : Enumerable(Call::Argument), binding = false) : String #

Formats arguments as type name, .... If binding is true, treat this as argument for a fun declaration.

def floating_type?(type_name) : Bool #

Returns true if type_name is a Crystal floating-type.

def literal(type_name, value) : String | Nil #

Generates a literal value suitable for Crystal code, using the value of type_name. type_name is a completely deduced Crystal type-name.

Returns nil if type_name is unknown (It's not built-in). Try #qualified_enum_name in that case if it might be an enum.

def number_literal(type_name, value) : String | Nil #

Returns the number literal of type_name with value. The result is valid a Crystal literal, and can be directly written.

def number_literal_suffix(type_name) : String | Nil #

Returns the literal-suffix for Crystal code, to signify a literal matching the intended type_name.

If type_name is unknown, returns nil.

def qualified_enum_name(type : Parser::Type, value : Int) : String | Nil #

Returns the qualified name of value in the enum called enum_name. Builds a .flags(...) list if the enum turns out to be a @[Flags].
