erl_internal(3erl)

🌸 NAME 🌸

okay so bestie, this is erl_internal(3erl) — the Erlang module definition for erl_internal — and the name literally means Internal Erlang definitions. 💅

---

✨ DESCRIPTION ✨

This module is where Erlang defines its BIFs, guard tests, and operators. No cap, it’s only of interest to programmers who manipulate Erlang code — like, code-manipulation main character energy 💖

---

💖 EXPORTS 💖

okay bestie, here’s the whole roster, no skips, no cap 🫶

🎀 add_predefined_functions(Forms) -> UpdatedForms

Types:

Forms = [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. Then it gives you back UpdatedForms, slay ✨

🧮 arith_op(OpName, Arity) -> boolean()

Types:

OpName = atom()
Arity = arity()

Returns true if OpName/Arity is an arithmetic operator, otherwise false. Simple vibe check, no drama 💜

🔥 bif(Name, Arity) -> boolean()

Types:

Name = atom()
Arity = arity()

Returns true if Name/Arity is an Erlang BIF that is automatically recognized by the compiler, otherwise false. The compiler already knows this one, iykyk 👑

🦋 bool_op(OpName, Arity) -> boolean()

Types:

OpName = atom()
Arity = arity()

Returns true if OpName/Arity is a Boolean operator, otherwise false. Boolean bestie behavior 🌈

⭐ comp_op(OpName, Arity) -> boolean()

Types:

OpName = atom()
Arity = arity()

Returns true if OpName/Arity is a comparison operator, otherwise false. Comparing things is literally the whole point 🎀

🛡️ guard_bif(Name, Arity) -> boolean()

Types:

Name = atom()
Arity = arity()

Returns true if Name/Arity is an Erlang BIF that is allowed in guards, otherwise false. Guard-duty icon behavior 🫶

🍓 list_op(OpName, Arity) -> boolean()

Types:

OpName = atom()
Arity = arity()

Returns true if OpName/Arity is a list operator, otherwise false. List operator? Obsessed 💖

🧚 op_type(OpName, Arity) -> Type

Types:

OpName = atom()
Arity = arity()
Type = arith | bool | comp | list | send

Returns the Type of operator that OpName/Arity belongs to. If it’s not an operator at all, it generates a function_clause error — no cap, that’s the deal 😭

💌 send_op(OpName, Arity) -> boolean()

Types:

OpName = atom()
Arity = arity()

Returns true if OpName/Arity is a send operator, otherwise false. Sending it, periodt 💅

🌸 type_test(Name, Arity) -> boolean()

Types:

Name = atom()
Arity = arity()

Returns true if Name/Arity is a valid Erlang type test, otherwise false. Valid type test? We love a clean vibe check ✨
