我正在尝试在VS Code中为基于Aurelia CLI的应用程序实施“F5”调试。 Aurelia CLI基于Gulp任务构建。我想设置一个运行au run --watch
的任务,并在按“F5”进行调试时启动此任务(“启动Chrome”选项)。
为au run --watch
命令创建基本任务非常简单。
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "0.1.0",
"command": "au",
"isShellCommand": true,
"tasks": [
{
"taskName": "watch",
"suppressTaskName": true,
"args": [
"run",
"--watch"
],
"isBuildCommand": false,
"isBackground": true
}
]
}
然后,当我按F5将其添加到“启动针对localhost的Chrome”调试配置时,我可以启动此任务:
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:9000",
"webRoot": "${workspaceRoot}",
"preLaunchTask": "watch"
}
我看到的问题是,由于此任务是一项无法完成的“监视”任务,因此代码永远不会启动Chrome标签页或启动调试会话。
我尝试在我的任务配置中添加了“problemMatcher”,但坦率地说,此功能的文档有点稀疏。我得到的错误输出似乎与JSON模式所说的不一致。希望有人可以帮助我。这是我当前的非工作任务配置。当我说非工作时,我的意思是任务成功运行,但VS Code没有注意到任务的观看部分已经开始。

"version": "0.1.0",
"command": "au",
"isShellCommand": true,
"tasks": [
{
"taskName": "watch",
"suppressTaskName": true,
"args": [
"run",
"--watch"
],
"isBuildCommand": false,
"isBackground": true,
"problemMatcher": {
"owner": "au",
"severity": "info",
"fileLocation": [
"relative",
"${workspaceRoot}"
],
"pattern": {
"regexp": "^BrowserSync Available At: http://localhost:3001$",
"file": 1
},
"watching": {
"activeOnStart": true,
"beginsPattern": "^File Changed: (.*)",
"endsPattern": "^Finished 'reload'"
}
}
}
]
}
作为参考,当我运行此任务时,这是命令的输出:
Starting 'readProjectConfiguration'...
Finished 'readProjectConfiguration'
Starting 'processMarkup'...
Starting 'processCSS'...
Starting 'copyFiles'...
Starting 'configureEnvironment'...
Finished 'copyFiles'

当我编辑并保存文件时,会在控制台输出中添加以下内容:

Finished 'readProjectConfiguration'

Starting 'processCSS'...
Starting 'copyFiles'...
Starting 'configureEnvironment'...

我们知道这一点,并且两个相应的GitHub问题是:
我们计划以两种方式改善这一点:
问题6209包含了如何解决此问题的步骤,并且您正走在正确的道路上:-)。应该有所不同的事情:
由于您不想匹配任何问题,请使用与任何内容都不匹配的正则表达式。类似的东西:
"pattern": {
"regexp": "__________"
}
更大的问题是,在第一次运行时,活动结束的信号不同,然后对文件更改做出反应。因此,endsPattern必须与BrowserSync Available At: http://localhost:3001
和Finished 'reload'
匹配。所以像/(?:BrowserSync Available At:)|(?:Finished 'reload')/
这样的正则表达式
beginPattern和"activeOnStart": true
是正确的。
