定制全局主题样式
Vant Weapp 使用 CSS 变量来实现定制主题。 关于 CSS 变量的基本用法，请参考 MDN 文档：
https://developer.mozilla.org/zh-CN/docs/Web/CSS/Using_CSS_custom_properties
定制全局主题样式
在 app.wxss 中，写入 CSS 变量，即可对全局生效：
page {
--button-danger-background-color: #C00000;
--button-danger-border-color: #D60000;
--button-primary-background-color: #13A7A0;
--button-primary-border-color: #15B4AA;
}
因为Vant 官方提供的配置文件存放在github中，很多时候网络不行进不了官网，所以我将其复制过来提供参考，若想获取更多更详细最新样式可以搜索下方官网链接：
vant-weapp 所有可用的颜色变量，请参考 Vant 官方提供的配置文件：

我有一大串格式化数据(例如JSON)，我想使用Psychinruby同时保留格式转储到YAML。基本上，我希望JSON使用literalstyle出现在YAML中:---json:|{"page":1,"results":["item","another"],"total_pages":0}但是，当我使用YAML.dump时，它不使用文字样式。我得到这样的东西:---json:!"{\n\"page\":1,\n\"results\":[\n\"item\",\"another\"\n],\n\"total_pages\":0\n}\n"我如何告诉Psych以想要的样式转储标量？解
我正在为一个项目制作一个简单的shell，我希望像在Bash中一样解析参数字符串。foobar"helloworld"fooz应该变成:["foo","bar","helloworld","fooz"]等等。到目前为止，我一直在使用CSV::parse_line，将列分隔符设置为""和.compact输出。问题是我现在必须选择是要支持单引号还是双引号。CSV不支持超过一个分隔符。Python有一个名为shlex的模块:>>>shlex.split("Test'helloworld'foo")['Test','helloworld','foo']>>>shlex.split('Test"
我有带有Logo图像的公司模型has_attached_file:logo我用他们的Logo创建了许多公司。现在，我需要添加新样式has_attached_file:logo,:styles=>{:small=>"30x15>",:medium=>"155x85>"}我是否应该重新上传所有旧数据以重新生成新样式？我不这么认为……或者有什么rake任务可以重新生成样式吗？ 最佳答案 参见Thumbnail-Generation.如果rake任务不适合你，你应该能够在控制台中使用一个片段来调用重新处理!关于相关公司
我有一个gem，它有一个根据Rails.env的不同行为的方法:defself.envifdefined?(Rails)Rails.envelsif...现在我想编写一个规范来测试这个代码路径。目前我是这样做的:Kernel.const_set(:Rails,nil)Rails.should_receive(:env).and_return('production')...没关系，只是感觉很丑。另一种方法是在spec_helper中声明:moduleRails;end而且效果也很好。但也许有更好的方法？理想情况下，这应该有效:rails=double('Rails')rails.sho

在许多ruby类之间共享记录器实例的最佳(正确)方法是什么？现在我只是将记录器创建为全局$logger=Logger.new变量，但我觉得有更好的方法可以在不使用全局变量的情况下执行此操作。如果我有以下内容:moduleFooclassAclassBclassC...classZend在所有类之间共享记录器实例的最佳方式是什么？我是以某种方式在Foo模块中声明/创建记录器还是只是使用全局$logger没问题？ 最佳答案 在模块中添加常量:moduleFooLogger=Logger.newclassAclassBclassC..
如何在出现异常时指定全局救援，如果您将Sinatra用于API或应用程序，您将如何处理日志记录？ 最佳答案 404可以在not_found方法的帮助下处理，例如:not_founddo'Sitedoesnotexist.'end500s可以通过调用带有block的错误方法来处理，例如:errordo"Applicationerror.Plstrylater."end错误的详细信息可以通过request.env中的sinatra.error访问，如下所示:errordo'Anerroroccured:'+request.env['si
我读过这个:Let’sstartwithasimpleRubyprogram.We’llwriteamethodthatreturnsacheery,personalizedgreeting.defsay_goodnight(name)result="Goodnight,"+namereturnresultend我的理解是，方法是定义在类中的函数或子程序，可以关联到类(类方法)或对象(实例方法)。那么，如果它不是在类中定义的，怎么可能是方法呢？ 最佳答案 当你在Ruby中以这种方式在全局范围内定义一个函数时，它在技术上变成了Obje
编辑:我稍微更改了规范，以更好地符合我的想象。好吧，我真的不想伪造C#属性，我想将它们合而为一并支持AOP。给定程序:classObjectdefObject.profile#magiccodehereendendclassFoo#Thisisthefakeattribute,itprofilesasinglemethod.profiledefbar(b)putsbenddefbarbar(b)puts(b)endcomment("thisreallyshouldbefixed")defsnafu(b)endendFoo.new.bar("test")Foo.new.barbar("t
假设我有:get'/'do$random=Random.rand()response.body=$randomend如果我每秒有数千个请求到达/，$random是否会被共享并“泄漏”到上下文之外，或者它会像getblock的“本地”变量一样？我想如果它是在get'/'do的上下文之外定义的，它确实会被共享，但我想知道在ruby中是否有我不知道的$机制。 最佳答案 ThispartoftheSinatraREADMEaboutscopeisalwayshelpfultoread但是，如果您只需要为请求保留变量，那么我认为我建议使用
