Module std/sys.vv
The sys module provides system-level capabilities and interpreter control.
Example:
import sys from "std/sys.vv"
import console from "std/console.vv"
console.print(sys.type(123)) // "int"

Exports
fun help()
extern "native"
Prints help information about the language and available built-ins.
Example:
sys.help()
fun phys_eq(a, b)
extern "native"
Checks if two values refer to the exact same object in memory (physical equality).
Example:
import sys from "std/sys.vv"
import console from "std/console.vv"
let a = [1]
let b = [1]
console.print(sys.phys_eq(a, b)) // false
console.print(sys.phys_eq(a, a)) // true
fun set_max_recursion_depth(depth)
extern "native"
Sets the maximum recursion depth allowed by the interpreter. Prevents stack overflow panics by throwing a catchable runtime error instead.
Example:
sys.set_max_recursion_depth(100)
fun get_max_recursion_depth()
extern "native"
Returns the current maximum recursion depth allowed by the interpreter.
Example:
import sys from "std/sys.vv"
import console from "std/console.vv"
console.print(sys.get_max_recursion_depth()) // 1000
fun type(v)
extern "native"
Returns the string representation of the type of the given value.
Example:
import sys from "std/sys.vv"
import console from "std/console.vv"
console.print(sys.type(123)) // "int"
console.print(sys.type("hello")) // "list"
console.print(sys.type({ a = 1 })) // "record"
fun str(v)
extern "native"
Returns the string representation of the given value.
Example:
import sys from "std/sys.vv"
import console from "std/console.vv"
console.print(sys.str(123)) // "123"
console.print(sys.str([1, 2, 3])) // "[1, 2, 3]"
console.print(sys.str(true)) // "true"
