flying-hero 96f6318101 📦 添加虚拟环境和启动脚本

新增:
- backend/venv/ - Python 虚拟环境
- backend/start.sh - 启动脚本（使用虚拟环境）
- backend/requirements.txt - 依赖列表
- .gitignore - 忽略虚拟环境和缓存文件

说明:
- 每个项目使用独立虚拟环境
- 避免依赖冲突
- 启动脚本自动创建和激活虚拟环境

@webassemblyjs/wasm-edit

Rewrite a WASM binary

Replace in-place an AST node in the binary.

Installation

yarn add @webassemblyjs/wasm-edit

Usage

Update:

import { edit } from "@webassemblyjs/wasm-edit";

const binary = [/*...*/];

const visitors = {
  ModuleImport({ node }) {
    node.module = "foo";
    node.name = "bar";
  }
};

const newBinary = edit(binary, visitors);

Replace:

import { edit } from "@webassemblyjs/wasm-edit";

const binary = [/*...*/];

const visitors = {
  Instr(path) {
    const newNode = t.callInstruction(t.indexLiteral(0));
    path.replaceWith(newNode);
  }
};

const newBinary = edit(binary, visitors);

Remove:

import { edit } from "@webassemblyjs/wasm-edit";

const binary = [/*...*/];

const visitors = {
  ModuleExport({ node }) {
    path.remove()
  }
};

const newBinary = edit(binary, visitors);

Insert:

import { add } from "@webassemblyjs/wasm-edit";

const binary = [/*...*/];

const newBinary = add(actualBinary, [
  t.moduleImport("env", "mem", t.memory(t.limit(1)))
]);

Providing the AST

Providing an AST allows you to handle the decoding yourself, here is the API:

addWithAST(Program, ArrayBuffer, Array<Node>): ArrayBuffer;
editWithAST(Program, ArrayBuffer, visitors): ArrayBuffer;

Note that the AST will be updated in-place.
