Vindicta.print

Outputs a message to the executor console at a specified severity level.

function Vindicta.print(level: number, ...: string): void

Synopsis

How it works

A native C function (printFn) registered on the Vindicta global table. It writes directly to the executor's internal console output buffer, which is rendered in the Vindicta UI. The level argument controls the severity styling of the message.

Under the hood

Implemented as a lua_CFunction that:

Reads the first argument as an integer severity level (0–3)
Concatenates remaining arguments with space separators
Dispatches the formatted string to the UI console's ring buffer
Applies coloring based on severity: white (0), blue (1), yellow (2), red (3)

iscclosure(Vindicta.print) returns true because it is a genuine C closureClosureA function value that captures its lexical environment. In Luau, closures come in two types: LClosure (Luau bytecode + Proto + upvalues) and CClosure (native C function pointer + upvalues)..

Usage

All severity levels

Vindicta.print(0, "Hello, World!")       "cc">-- plain print
Vindicta.print(1, "Script loaded")        "cc">-- info
Vindicta.print(2, "Deprecated API used")  "cc">-- warn
Vindicta.print(3, "Failed to hook target") "cc">-- error

Conditional logging helper

local function log(msg, isError)
  local level = isError and 3 or 1
  Vindicta.print(level, "[MyScript]", msg)
end

log("Initialized", false) "cc">-- info
log("Hook failed!", true)  "cc">-- error

Parameters

level number

Severity level. 0 = print (plain), 1 = info (blue), 2 = warn (yellow), 3 = error (red).

... string

One or more string values to log. Multiple arguments are concatenated with a space separator.

Log Levels

Level	Name	Style	Use Case
0	print	Plain white	General output, debugging
1	info	Blue label	Informational messages, status updates
2	warn	Yellow label	Deprecation notices, non-fatal issues
3	error	Red label	Fatal errors, hook failures, exceptions

C Implementation

This function is implemented natively (printFn) and exposed through the Vindicta global table. It is not a Luau closure — iscclosure(Vindicta.print) returns true.
