Programmatically set options for grunt task?
提问by Nick Heiner
I have a grunt task that looks at options with grunt.option('foo'). If I'm calling this task from grunt.task.run('my-task'), how can I change those arguments?
我有一个繁重的任务，它查看带有grunt.option('foo'). 如果我从 调用此任务grunt.task.run('my-task')，我该如何更改这些参数？
I'm looking for something like:
我正在寻找类似的东西：
grunt.task.run('my-task', {foo: 'bar'});
which would be the equivalent of:
这相当于：
$ grunt my-task --foo 'bar'
Is this possible?
这可能吗？
(This questionis another issue I ran in to but is not exactly the same, because in this case I don't have access to the original task's Gruntfile.js.)
（这个问题是我遇到的另一个问题，但并不完全相同，因为在这种情况下，我无法访问原始任务的 Gruntfile.js。）

Looks like I can use the following:
看起来我可以使用以下内容：
grunt.option('foo', 'bar');
grunt.task.run('my-task');
It feels a bit odd to set the options globally instead of just for that command, but it works.
全局设置选项而不是仅针对该命令设置选项感觉有点奇怪，但它有效。

If you can use task-based config options instead of grunt.option, this should work to give you more granular control:
如果您可以使用基于任务的配置选项而不是 grunt.option，这应该可以为您提供更精细的控制：
grunt.config.set('task.options.foo', 'bar');

Create a new task which set the option, then call the modified task. This is a real life example with assemble:
创建一个设置选项的新任务，然后调用修改后的任务。这是一个真实的assemble例子：
grunt.registerTask('build_prod', 'Build with production options', function () {
grunt.config.set('assemble.options.production', true);
grunt.task.run('build');
});

In addition to @Alessandro Pezzato
除了@Alessandro Pezzato
Gruntfile.js:
Gruntfile.js：
grunt.registerTask('build', ['clean:dist', 'assemble', 'compass:dist', 'cssmin', 'copy:main']);
grunt.registerTask('build-prod', 'Build with production options', function () {
grunt.config.set('assemble.options.production', true);
grunt.task.run('build');
});
grunt.registerTask('build-live', 'Build with production options', function () {
grunt.option('assemble.options.production', false);
grunt.task.run('build');
});
Now you can run
现在你可以运行
$ grunt build-prod
$ grunt build-prod
-OR-
-或者-
$ grunt build-live
$ grunt build-live
They will both do the full task 'build' and respectively pass a value to one of the options of assemble, namely production 'true' or 'false'.
他们都将完成完整的任务“构建”，并分别将一个值传递给assemble的选项之一，即生产“真”或“假”。
In addition to illustrate the assemble example a bit more:
除了更多地说明汇编示例之外：
In assemble you have the option to add a {{#if production}}do this on production{{else}}do this not non production{{/if}}
在 assemble 中，您可以选择添加一个 {{#if production}}do this on production{{else}}do this not non production{{/if}}

grunt is all programmatic.. so if you have set options on tasks before, you have done this programmatically.
grunt 都是程序化的……所以如果你之前已经为任务设置了选项，那么你已经以程序化的方式完成了。
just use grunt.initConfig({ ... })to set options for tasks.
仅用于grunt.initConfig({ ... })设置任务选项。
and if you already initialized, and need to change configuration afterwards, you can do something like
如果您已经初始化，之后需要更改配置，您可以执行以下操作
grunt.config.data.my_plugin.goal.options = {};
grunt.config.data.my_plugin.goal.options = {};
I am using it for my project and it works.
我在我的项目中使用它并且它有效。

I recently ran up against this same issue: programmatically setting grunt options and running tasks multiple times from within a single parent task. As @Raphael Verger mentions, this is not possible, as grunt.task.rundefers the running of the task until the current task is finished:
我最近遇到了同样的问题：以编程方式设置 grunt 选项并从单个父任务中多次运行任务。正如@Raphael Verger 提到的，这是不可能的，因为grunt.task.run将任务的运行推迟到当前任务完成：
grunt.option('color', 'red');
grunt.task.run(['logColor']);
grunt.option('color', 'blue');
grunt.task.run(['logColor']);
Will result in the color bluebeing logged twice.
将导致蓝色被记录两次。
After some fiddling, I came up with a grunt task that allows dynamically specifying a different option/config for each sub-task to be run. I've published the task as grunt-galvanize. Here's how it works:
经过一番折腾，我想出了一个 grunt 任务，它允许为每个要运行的子任务动态指定不同的选项/配置。我已将任务发布为grunt-galvanize。这是它的工作原理：
var galvanizeConfig = [
{options: {color: 'red'}, configs: {}},
{options: {color: 'blue'}, configs: {}}
];
grunt.option('galvanizeConfig', galvanizeConfig);
grunt.task.run(['galvanize:log']);
This will log redthen blue, as desired by running the logtask with each of the options/configs specified in galvanizeConfig.
这将记录红，然后蓝色，通过运行如期望的日志与每个指定的选项/ CONFIGS的任务galvanizeConfig。
