[英]Programmatically set options for grunt task?
I have a grunt task that looks at options with grunt.option('foo')
. 我有一个grunt任务,用
grunt.option('foo')
查看选项。 If I'm calling this task from grunt.task.run('my-task')
, how can I change those arguments? 如果我从
grunt.task.run('my-task')
调用此任务, grunt.task.run('my-task')
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: 这将相当于:
$ grunt my-task --foo 'bar'
Is this possible? 这可能吗?
( This question is 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。)
如果您可以使用基于任务的配置选项而不是grunt.option,那么这应该可以为您提供更精细的控制:
grunt.config.set('task.options.foo', 'bar');
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. 设置全局选项而不仅仅是针对该命令感觉有点奇怪,但它有效。
Create a new task which set the option, then call the modified task. 创建一个新任务,设置该选项,然后调用修改后的任务。 This is a real life example with assemble :
这是汇编的真实例子:
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 现在你可以跑了
$ grunt build-prod
-OR- -要么-
$ 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'. 他们都将执行完整任务'build'并分别将值传递给汇编选项之一 ,即生产'true'或'false'。
In addition to illustrate the assemble example a bit more: 除了说明组装示例之外:
In assemble you have the option to add a {{#if production}}do this on production{{else}}do this not non production{{/if}}
在汇总时,您可以选择添加
{{#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是所有程序化的..所以如果您之前已经设置了任务选项,那么您已经以编程方式完成了此操作。
just use grunt.initConfig({ ... })
to set options for tasks. 只需使用
grunt.initConfig({ ... })
来设置任务选项。
and if you already initialized, and need to change configuration afterwards, you can do something like 如果你已经初始化,并且之后需要更改配置,你可以做类似的事情
grunt.config.data.my_plugin.goal.options = {};
I am using it for my project and it works. 我正在将它用于我的项目并且它有效。
I recently ran up against this same issue: programmatically setting grunt options and running tasks multiple times from within a single parent task. 我最近遇到了同样的问题:以编程方式在单个父任务中多次设置grunt选项和运行任务。 As @Raphael Verger mentions, this is not possible, as
grunt.task.run
defers the running of the task until the current task is finished: 正如@Raphael Verger所提到的,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 blue being 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. 经过一番摆弄后,我想出了一个笨拙的任务,允许为每个要运行的子任务动态指定不同的选项/配置。 I've published the task as grunt-galvanize .
我已经将这项任务发布为grunt-galvanize 。 Here's how it works:
以下是它的工作原理:
var galvanizeConfig = [
{options: {color: 'red'}, configs: {}},
{options: {color: 'blue'}, configs: {}}
];
grunt.option('galvanizeConfig', galvanizeConfig);
grunt.task.run(['galvanize:log']);
This will log red then blue , as desired by running the log task with each of the options/configs specified in galvanizeConfig
. 通过使用
galvanizeConfig
指定的每个选项/配置运行日志任务,这将根据需要记录红色然后蓝色 。
