开发过程宏时经常需要处理结构体或枚举体上的属性参数,如下 Command 结构体的args字段有属性each = "arg", 代码语言:rust 复制 #[derive(Builder)]pubstructCommand{executable:String,#[builder(each ="arg")]args:Vec<String>,#[builder(each ="env")]env:Vec<String>,current_dir:Option<String>,} AST ...

current_dir(&source_dir); 创建configure命令,它将在系统上准备好软件的构建环境。 Line 201 configure.arg(format!("--prefix={}", search().to_string_lossy())); 为configure命令添加前缀参数,即输出目的目录。 Line 203~222 if env::var("TARGET").unwrap() != env::var("HOST").unwrap() {...

构建集成测试时会设置CARGO_BIN_EXE_<name>环境变量<https://doc.rust-lang.org/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-crates>以便它可以使用env宏<https://doc.rust-lang.org/std/macro.env.html>来定位可执行文件。传递目标选择标志将只构建指定的目标。注意--bin、-...
对于示例4, 用std::env::args()获取参数,再手写简单的解析步骤。 对于示例1, 可以用 clap crate 的 derive 功能,将结构体与命令行参数相关联。 clap 可能有点重,不过有一些零成本抽象的 crates 也能用来解析命令行参数。 mxdwtools 回复 Moe 拥有者 11个月前 现在已经解决了,用的std::os::unix::proces...
