  "description_en": "IDA Pro plugin built on the Keystone assembler engine that patches a binary from typed assembly, fills an address range with instructions or raw bytes and searches the loaded binary for assembly instructions. It assembles Arm, Arm64, Hexagon, MIPS, PowerPC, SPARC, SystemZ and 16-, 32- and 64-bit x86 code, shows the encoding while you type, can pad with NOPs up to the next instruction boundary, keeps the original instruction in an IDA comment and can undo the last patch.",
  "description_zh": "基于 Keystone 汇编引擎的 IDA Pro 插件：可直接输入汇编指令修补二进制文件，用指令或原始字节填充一段地址范围，并在已加载的二进制文件中搜索汇编指令。它支持 Arm、Arm64、Hexagon、MIPS、PowerPC、SPARC、SystemZ 以及 16/32/64 位 x86，输入时即时显示编码，可用 NOP 填充到下一条指令边界，在 IDA 注释中保留原指令，并可撤销上一次修补。",
