SketchUp已初始化常量？

我以前从未注意到这一点，但在测试我的一个插件时，我决定在加载插件。我的代码是> 我的错误信息是： c:/users/administrator/appdata/roaming/sketchup/sketchup 2017/sketchup/plugins/medeek_foundation_ext/medeek_foundation_load.rbs:39: warning: already initialized constant Medeek_Engineering_Inc_Extensions::MedeekFoundationPlugin::THIS_DIRc:/users/administrator/appdata/roaming/sketchup/sketchup 2017/sketchup/plugins/medeek_foundation_ext/medeek_foundation_load.rbs:36: warning: previous definition of THIS_DIR was here 我真的不知道这里出了什么问题，也不知道我做错了什么。我想我以前从来没有见过这个，因为我通常不显示插件load.rbz中的控制台由TIG在post#2中解决您没有做错什么。Ruby希望您只定义一次常量。当您重新分配它时，会出现一条警告消息-如您所见-但它仍然会更改。有很多方法可以在代码中重新定义一个常量来抑制错误，但是在你的情况下，为什么不重新定义一次呢，这… 您没有做错什么。 Ruby希望您只定义一次常量。当您重新分配它时，会出现一条警告消息-如您所见-但它仍然被更改。有一些方法可以在代码中重新定义一个常量来抑制错误，但是在您的情况下，为什么不重新定义它以只定义一次呢，> 您也可以这样做… … OR> I\"m not sure I fully understand what the double pipe or equals is doing in this case, never seen that operator before.I really do learn something every day as a developer. Ruby\"s Or Equals operator is covered in this topic https://ruby-doc.org/core-2.4.0/doc/syntax/assignment_rdoc.html#label-Abbreviated+Assignment 16 medeek: I\"m not sure I fully understand what the double pipe or equals is doing in this case Just an other source… ruby-style-guide#self-assignment 1 …andafter that ruby-style-guide#double-pipe-for-uninit 1 In this specific case this will suffice: This works all the way back to SketchUp 2014, which is quite ancient by now. Trying to support older SU versions will make the code quite a bit bulkier and uglier as it doesn\"t support a number of newer methods and idioms. EDIT: Not to mention SU API, like HtmlDialogs. In the general case I\"d use a intermediate variable and set the constant once. This is just 3 lines of code and has a single level of indentation which makes it more> I agree the three line version is more compact and more readable, I will switch out my current code… yet again. … but it won\"t suppress the warnings. The warnings are there because the Ruby core devs are heading towards true constants. Already they have implemented no dynamic constant assignment within methods. The average user is only going to load your code once, so they\"ll not likely run into the warning. It is you (the dev) who reloads your code during development that sees the warning. There are several ways to handle this so constants are loaded once. The simplest is to have all your constants in one file that is loaded the first time. Then during dev when you are tweaking things you need only reload the file that was tweaked. The other way is to use the same pattern we use to prevent multiple menu items … … ie, the first file to load: module Medeekmodule NiftyFoundationif !@loaded# define constants hereend# define methods and classes, or load other files here, etc.endend …即，要加载的最后一个文件： module Medeekmodule NiftyFoundationif !@loaded# define commands, menus and> I prefer not to clutter the code with checks if the constant is already defined. Instead the debug/test reload scrip can just hide the warnings. It\"s not very important if this is \"proper\" Ruby as it\"s never used in production, just for testing. This also has the benefit that it allows you to redefine the constants without restarting SketchUp when testing, at least for as long as Ruby supports it. # Reload extension.## @param clear_console [Boolean] Whether console should be cleared.# @param undo [Boolean] Whether last oration should be undone.## @return = nilDir.glob(File.join(PLUGIN_ROOT, \"**/*.{rb,rbe}\")).each { |f| load(f)> oh yea, a 3d way. Ruby is so multi-paradigm. def> … and then in use: quietly do# load my filesend
