libunbound

Android native library for dynamically interacting with compiled Hermes. This is mainly intended to be used by Discord RNA client mods.

Usage

build.gradle.kts:

repositories {
  mavenCentral()
}

dependencies {
  implementation("dev.rushii:libunbound:1.0.0")
}

Use after Hermes (libhermes.so) has been loaded into the process:

// Returns the HBC version supported by the loaded runtime
// https://github.com/discord/hermes/blob/0.76.2-discord/include/hermes/BCGen/HBC/BytecodeVersion.h#L23
LibUnbound.getHermesRuntimeBytecodeVersion()

// Check to verify whether some bytes are hermes bytecode (possibly inaccurate)
LibUnbound.isHermesBytecode(/* bytes */)
