I. Specification of modulesFirst think about why the module is important?Because of the module, we can more easily use other people's code, want what function, load what module.However, this has a premise, that is, we must write the module in the same way, otherwise you have your writing, I have my writing, it is not messy set! This is even more important considering that the JavaScript module does not yet have an official specification.Currently, there are two types of JavaScript module

module names.After Drupal 8 and after, you should use the Const keyword instead of the define () function to define constants, because it is more efficientNote that const cannot be used in PHP expressions, so in conditional judgment and non-literal value??? , you should still use the Define () functionGlobals (Global Variables)When you define a global variable, you should start with an underscore and a module/topic nameClasses (Class)Class names should be named with the Hump (that is, the first

Basic requirements 1.1 Program Structure analysis, easy to understand, a single function of the number of programs can not exceed 100 lines. 1.2 What to do, to be simple, straightforward when the code is streamlined to avoid garbage programs. 1.3 Use standard library functions and public functions as much as possible. 1.4 Do not arbitrarily define global variables, try to use local variables. 1.5 use parentheses to avoid ambiguity. 2. Readability Requirements 2.1 Readability first, effici

There is no doubt that anomaly specifications are a compelling feature. It makes the code easier to understand because it clearly describes what kind of exception a function can throw. But it's not just an interesting note. The compiler can sometimes detect inconsistencies in the exception specification at compile time. And if a function throws an exception that is not in the exception specification range, the system can detect the error at run time,

GBIC is the abbreviation of Giga Bitrate Interface Converter, is an interface device which converts gigabit electrical signals into light signal. The Gbic design can be used for hot-swappable.

For Engineers familiar with the C/C ++ or Java language, JavaScript is flexible, easy to understand, and requires relatively loose code formats. It is easy to learn and use it in your own code. Because of this, JavaScript coding standards are often despised. Fixing and complementing during the development process will eventually become a nightmare for subsequent maintenance personnel. The long-term value of software is directly proportional to the coding quality. Coding

The following is a brief analysis of php and database code development specifications. For more information, see 1. naming rules for various variables in PHP (1) directory naming, file naming, and local variable naming:English name words and verbs are used. the following dashes are used to separate words. all letters are in lower case.

This shows the encoding specification from the PHPCMS development documentation. although it is called the PHPCMS development specification, I think this applies to all PHP programming. After writing so many PHP codes, many codes may not be able to compare and correct the codes in the future. Note: This shows the encoding specification from the PHPCMS development documentation. although it is called the PHPCMS development specification, I think this is the case for all PHP programming. After wri

PHP programming standards have always been written in the php function style. all variables, functions, and classes are written in lower case and separated by strikethroughs, I have always been reluctant to use the camper code specification. I personally think it is very troublesome to write code between uppercase and lowercase letters, and my PHP functions are all in lower case. why don't I use this format? Good code writing habits + good comments habits + php?entor = instruction manual A te
