Question

我在使用正则表达式解析buildc的构建输出时遇到了一些问题。

输出看起来像

   Compiling svd2rust v0.2.1 (file:///C:/trust/svd2rust)
error: expected one of `=>`, `@`, `if`, or `|`, found `Some`
  --> src\main.rs:56:9
   |
56 |         Some("all") =>
   |         ^^^^
error: aborting due to previous error
error: Could not compile `svd2rust`.
To learn more, run the command again with --verbose.

我目前的任务看起来像是：

{
    "version": "0.1.0",
    "command": "cargo",
    "isShellCommand": true,
    "args": ["build"],
    "problemMatcher": {
        "owner": "build",
        "fileLocation": ["relative", "${workspaceRoot}"],
        "pattern": {
            "regexp": "(error):(.*)\\s+-->\\s+(.*):(\\d+):(\\d+)",
            "file": 3,
            "line": 4,
            "column": 5,
            "severity": 1,
            "message": 2
        }
    }
}

According to regex101，看起来正则表达式应匹配相应的部分。

根据VS Code documentation，您需要一个多行问题匹配器。这可能有用;我没有测试它：

{
    "version": "0.1.0",
    "command": "cargo",
    "isShellCommand": true,
    "args": ["build"],
    "problemMatcher": {
        "owner": "build",
        "fileLocation": ["relative", "${workspaceRoot}"],
        "pattern": [{
            "regexp": "(error):(.*)",
            "severity": 1,
            "message": 2
        },{
            "regexp": "-->\\s+([^:]*):(\\d+):(\\d+)",
            "file": 1,
            "line": 2,
            "column": 3
        }]
    }
}

正确使用Rust v1.20.0的正则表达式：

"pattern": [{
    "regexp": "(error(?:\\[E\\d{4}\\])?|warning):\\s(.*)",
    "severity": 1,
    "message": 2
},{
    "regexp": "-->\\s+([^:]*):(\\d+):(\\d+)",
    "file": 1,
    "line": 2,
    "column": 3
}]

Visual Studio代码任务正则表达式未捕获构建错误输出
