This module defines Erlang BIFs, guard tests, and operators. This module is only of interest to programmers who manipulate Erlang code.
add_predefined_functions(Forms) -> UpdatedFormsForms = [erl_parse:abstract_form() | erl_parse:form_info()]UpdatedForms =
[erl_parse:abstract_form() | erl_parse:form_info()]Adds to Forms the code for the standard pre-defined functions (such as module_info/0) that are to be included in every module.
arith_op(OpName, Arity) -> boolean() OpName = atom()Arity = arity()Returns true if OpName/Arity is an arithmetic operator, otherwise false.
bif(Name, Arity) -> boolean() Name = atom()Arity = arity()Returns true if Name/Arity is an Erlang BIF that is automatically recognized by the compiler, otherwise false.
bool_op(OpName, Arity) -> boolean() OpName = atom()Arity = arity()Returns true if OpName/Arity is a Boolean operator, otherwise false.
comp_op(OpName, Arity) -> boolean() OpName = atom()Arity = arity()Returns true if OpName/Arity is a comparison operator, otherwise false.
guard_bif(Name, Arity) -> boolean() Name = atom()Arity = arity()Returns true if Name/Arity is an Erlang BIF that is allowed in guards, otherwise false.
list_op(OpName, Arity) -> boolean() OpName = atom()Arity = arity()Returns true if OpName/Arity is a list operator, otherwise false.
op_type(OpName, Arity) -> Type OpName = atom()Arity = arity()Type = arith | bool | comp | list | sendReturns the Type of operator that OpName/Arity belongs to, or generates a function_clause error if it is not an operator.
send_op(OpName, Arity) -> boolean() OpName = atom()Arity = arity()Returns true if OpName/Arity is a send operator, otherwise false.
type_test(Name, Arity) -> boolean() Name = atom()Arity = arity()Returns true if Name/Arity is a valid Erlang type test, otherwise false.
