Function Documentation

◆ rb_alias_variable()

void rb_alias_variable	(	ID	dst,
		ID	src
	)

Aliases a global variable.

Did you know that you can alias a global variable? It is like aliasing methods:

alias $dst $src

This C function does the same thing.

Parameters

[in]	dst	Destination name.
[in]	src	Source name.

Postcondition: A global variable named dst is defined to be an alias of a global variable named src.

Definition at line 987 of file variable.c.

◆ rb_attr_get()

VALUE rb_attr_get	(	VALUE	obj,
		ID	name
	)

Identical to rb_ivar_get()

Parameters

[in]	obj	Target object.
[in]	name	Target instance variable to query.

Return values

RUBY_nil	No such instance variable.
otherwise	The value assigned to the instance variable.

Definition at line 1358 of file variable.c.

◆ rb_autoload_load()

VALUE rb_autoload_load	(	VALUE	space,
		ID	name
	)

Kicks the autoload procedure as if it was "touched".

Parameters

[out]	space	Namespace where autoload is defined.
[in]	name	Name of the autoloaded constant.

Return values

RUBY_Qfalse	No such autoload.
RUBY_Qtrue	Autoload successfully initiated.

Note: As an autoloaded library is expected to define space::name, it is a nature of this function to have process-global side effects.; Multiple threads can simultaneously call this API. It blocks then. That must not last indefinitely but can take longer than you expect.

Definition at line 2986 of file variable.c.

◆ rb_autoload_p()

VALUE rb_autoload_p	(	VALUE	space,
		ID	name
	)

Queries if an autoload is defined at a point.

Parameters

[in]	space	Namespace where autoload is defined.
[in]	name	Name of the autoloaded constant.

Return values

RUBY_Qnil	No such autoload.
otherwise	The feature (path) registered at `space::name`.

Definition at line 3024 of file variable.c.

◆ rb_class_name()

VALUE rb_class_name ( VALUE obj )

Queries the name of the given object's class.

Parameters

[in] obj Arbitrary object.

Returns: An instance of rb_cString representing obj's class' path.

Definition at line 412 of file variable.c.

Referenced by rb_any_to_s().

◆ rb_class_path()

VALUE rb_class_path ( VALUE mod )

Identical to rb_mod_name(), except it returns #<Class: ...> style inspection for anonymous modules.

Parameters

[in] mod An instance of rb_cModule.

Returns: An instance of rb_cString representing mod's path.

Definition at line 293 of file variable.c.

Referenced by rb_class_name(), and rb_profile_frame_classpath().

int rb_const_defined_at	(	VALUE	space,
		ID	name
	)

Identical to rb_const_defined(), except it doesn't look for parent classes.

Definition at line 3466 of file variable.c.

◆ rb_const_get()

VALUE rb_const_get	(	VALUE	space,

◆ rb_const_get_at()

VALUE rb_const_get_at	(	VALUE	space,
		ID	name
	)

Identical to rb_const_defined_at(), except it returns the actual defined value.

Parameters

[in]	space	Target namespace.
[in]	name	Target name to query.

Exceptions

rb_eNameError No such constant.

Returns: The defined constant.

Definition at line 3157 of file variable.c.

Referenced by rb_define_module_id_under().

◆ rb_const_get_from()

VALUE rb_const_get_from	(	VALUE	space,
		ID	name
	)

Identical to rb_const_defined_at(), except it returns the actual defined value.

It can also be seen as a routine identical to rb_const_get(), except it doesn't return a private constant.

Parameters

[in]	space	Target namespace.
[in]	name	Target name to query.

Exceptions

rb_eNameError No such constant.

Returns: The defined constant.

Definition at line 3145 of file variable.c.

◆ rb_const_list()

VALUE rb_const_list ( void * data )

This is another mysterious API that comes with no documents at all.

It seems it expects some specific data structure for the passed pointer. But the details has never been made explicit. It seems nobody should use this API.

Referenced by rb_mod_constants().

◆ rb_const_remove()

VALUE rb_const_remove	(	VALUE	space,
		ID	name
	)

Parameters

[out]	space	Target namespace.
[in]	name	Variable name to remove, either in Symbol or String.

Returns: What was removed.

Precondition: Constant named space::name is deleted.

Note: In case what was removed was in fact a module or a class, this operation does not affect its name. Which means when people for instance look at it using p etc., it still introduces itself using the deleted name. Can confuse people.

Definition at line 3267 of file variable.c.

◆ rb_const_set()

void rb_const_set	(	VALUE	space,
		ID	name,
		VALUE	val
	)

Parameters

[in]	obj	Target object.
[in]	name	Target instance variable to query.

Return values

◆ rb_mod_const_at()

void* rb_mod_const_at	(	VALUE	mod,
		void *	data
	)

This API is mysterious.

It has been there since the initial revision. No single bits of documents has ever been written. The function name doesn't describe anything. What should be passed to the argument, or what should be the return value, are not obvious. Yet it has evolved over time. The source code is written in counter-intuitive way (as of 3.0).

Simply put, don't try to understand this API.

Definition at line 3345 of file variable.c.

◆ rb_mod_const_of()

void* rb_mod_const_of	(	VALUE	mod,
		void *	data
	)

This is a variant of rb_mod_const_at().

As a result, it is also mysterious. It seems it iterates over the ancestry tree of the module. But what that means is beyond a human brain.

Definition at line 3362 of file variable.c.

Referenced by rb_mod_constants().

◆ rb_mod_constants()

VALUE rb_mod_constants	(	int	argc,
