naming-conventions

问题 In shell scripting, even though I use Java or Python style naming convention, I am still unclear about naming a constant. Many conventions suggest me to use "capital letter" together with "underscore" for naming a constant e.g. MY_CONSTANT , PI . But in Bash , this may conflict with environment variables. So, what is the right naming convention for Bash constants? 回答1: Good question! Together with the question you are linking, there is another related question in Unix & Linux: Are there

Which of these ways is more readable for Boolean Method in Python? document.is_editable document.editable document.has_editable

问题 Quite often in PHP model code (at least in my own such code) there are direct references to MySQL table and field names, and since MySQL identifiers are for the most part case-insensitive I typically use the under_score naming convention to make those identifiers a bit more readable. At the same time however, it seems that most folks use camelCase conventions when they create PHP class libraries, and I've been trying to do that, too. On top of that, the PHP built-in functions themselves are

问题 So, I'm normally a ruby programmer, so my grasp of Java conventions is shaky at best. If I have a class A and want to define a method to add two instances of that class, what's the convention on the behaviour and return type? public class A { //... public NotSureWhatTypeItShouldReturn add (A that) { /* ... */ } Should I return a boolean indicating success and modify the target, or return a modified copy of the target and throw an exception on error Which fits with the normal Java convention

问题 Android 2.3.3. I have a question regarding naming the IDs in Android. Let's say I have two buttons in Activity1 (save and cancel). I name them (IDs) as btnSave and btnCancel. Now I have Activity2, where in I have save and cancel buttons as well. Both does the same functionality. What will happen if I give the IDs as btnSave and btnCancel. Will i face a problem while compiling? When I press, R.id. and ctrl+space, will I get two btnSave and btnCancel(s) to choose from? And most importantly, Why

问题 I prefer to use long identifiers to keep my code semantically clear, but in the case of repeated references to the same identifier, I'd like for it to "get out of the way" in the current scope. Take this example in Python: def define_many_mappings_1(self): self.define_bidirectional_parameter_mapping("status", "current_status") self.define_bidirectional_parameter_mapping("id", "unique_id") self.define_bidirectional_parameter_mapping("location", "coordinates") #etc... Let's assume that I really

问题 I have a project that uses Spring MVC to create and handle multiple REST endpoints. I'm currently working on using Jackson to automatically handle the seralization/deserialization of JSON using the @RequestBody and @ResponseBody annotations. I have gotten Jackson working, so I've got a starting point. My problem is that our old serialization was done manually and used Pascal casing instead of Camel casing ("MyVariable" instead of "myVariable"), and Jackson does Camel casing by default. I know

问题 Suppose that I have a database with 1 table named Products . So, I go through the Db First approach and create an EF model in VS 2012 with pluralize and singularize option. So, the model creates a Product entity for me, and default naming convention maps this entity to the dbo.Products table. Now I want to change this behavior. In fact I want to create a custom convention to map ProductModel entity to the dbo.Products table. Is this possible?! If so, how? Update: My goal to do it... As you

问题 This is a newbie question... I am looking at the default asp.net mvc3 project and noticed that there is a controller called: public class AccountController : Controller I looked throughout the code and couldn't find a place that specified AccountController maps to /Account/ for the URL. I discovered that you can change the routing using routes.MapRoute(..) in the Global.asax , but I still don't know where they specified that AccountController maps to /Account/. If it is assumed from the class

问题 I have a couple of cases where I have the same underlying value being represented as multiple types. Example : userIDString := r.URL.Query("id") userID, err := strconv.Atoi(userIDString) I need to use both the above variables at different places. Similarly recordSeparator = rune(30) recordSeparatorString = string(30) Is my approach to naming such variables considered idiomatic go ? If not what would be the ideal naming convention for such cases ? PS: I don't think this question is primarily
