class Cradare2::Gdb::Client

• Cradare2::Gdb::Client
• Reference
• Object

Overview

Lightweight, standalone GDB Remote Serial Protocol (RSP) client over TCP. Allows zero-dependency memory querying, register inspection, and hardware canary checks directly against PCSX2, QEMU, or gdbserver without spawning a radare2 process.

Defined in:

cradare2/gdb/client.cr

Constructors

• .new(host : String = "127.0.0.1", port : Int32 = 1234)

Class Method Summary

• .calculate_checksum(payload : String) : UInt8

  Computes the 8-bit modulo 256 checksum for a GDB RSP payload.

• .format_packet(payload : String) : String

  Formats a command string into a complete GDB packet with start mark '$' and checksum.
