Gulp 更改整个任务的工作目录 [英] Gulp change working directory for entire task

问题描述

我正在处理一个 gulp 文件，其中包含我网站前端和后端的任务.
例如，下面的任务会将我的脚本连接到 app.js:

I'm working on a gulp file that contains tasks for both the frontend and the backend of my site.
The task below for example will concat my scripts into app.js:

gulp.task 'frontend:scripts', ->
    gulp.src frontendPath(scriptsFolder, scriptsPattern)
        .pipe sourcemaps.init()
        .pipe coffee()
        .pipe concat 'app.js'
        .pipe sourcemaps.write('.')
        .pipe gulp.dest frontendPath(tempFolder, scriptsFolder)

如您所见，我创建了一个帮助程序来提供正确的前端路径:

As you can see I've created a helper to provide the correct frontend path:

frontendPath = (dirs...) -> path.join.apply null, ['frontend'].concat(dirs)

但我必须非常小心，我的任务的所有步骤(尤其是 .src 和 .dest)都在前端文件夹中执行.

But I have to be really careful that all the steps of my task (especially .src and .dest) are executed in the frontend folder.

我知道您可以使用 { cwd: 'frontend' } 选项来更改 .src 和 .dest 的工作目录.但是有没有办法更改任务的整个工作目录?

I know that you can use the { cwd: 'frontend' } option to change the working directory for .src and .dest. But is there a way to change the whole working directory for a task?

推荐答案

使用process.chdir来改变工作目录.我们可以在 gulpfile 中的任何位置进行更改，或者根据您的情况，在任务中进行更改.

Use process.chdir to change the working directory. We can make the change anywhere in a gulpfile, or in your situation, change it within a task.

gulp.task('frontend', function(){
  process.chdir('...');
  gulp.src(...)
});

gulp.task('backend', function(){
  process.chdir('...');
  gulp.src(...)
});

确保使用最新版本的 gulp，此功能似乎是最近添加的.

Make sure using the latest version of gulp, this feature seems to be added recently.
