  "description_en": "Command-line decompiler that parses a WebAssembly binary or text-format module with Binaryen and emits pseudo-C: globals, imported and defined functions with their locals and control flow, and a preamble of C helpers for WebAssembly operations. Several modules can be decompiled into one file with module-name prefixes, a memdump mode writes the module’s memory and table to files instead, and an Emscripten build of wasmdec powers an online demo. Development stopped at version 1.2.1 in 2018.",
  "description_zh": "命令行反编译器，借助 Binaryen 解析 WebAssembly 二进制或文本格式模块，输出伪 C 代码：包括全局变量、导入与已定义的函数及其局部变量和控制流，并附带实现 WebAssembly 运算的 C 辅助函数前导部分。可将多个模块反编译到同一文件并以模块名作前缀；memdump 模式则改为把模块的内存和表写入文件。wasmdec 自身的 Emscripten 构建支撑着一个在线演示。开发停留在 2018 年的 1.2.1 版。",

    "Input is a .wasm binary or .wast text module. The asm.js mode needs a compile-time flag that the Makefile does not set; parsing relies on the pinned 2018 Binaryen and may reject newer WebAssembly features.",
    "Output is pseudo-C. Tests decompile seven bundled fixtures and spec testsuite cases and check exit status.",
    "The examples include machine-translated code from the commercial game diep.io; rights to that output remain with the original owner.",

    "输入是 .wasm 二进制或 .wast 文本模块。asm.js 模式需要 Makefile 未设置的编译标志；解析依赖固定的 2018 年 Binaryen，可能无法载入较新的 WebAssembly 特性。",
    "输出为伪 C。测试会反编译七个随附样本和规范测试套件样本，并检查退出状态。",
    "示例包含商业游戏 diep.io 的机器翻译代码；该输出的权利仍归原权利人所有。",
