Idea的live template参数中的预定义功能

Predefined Functions to Use in Live Template Variables

Item	Description
`annotated("annotation qname")`	Creates a symbol of type with an annotation that resides at the specified location. For an example, see Live Templates in the iterations group.
`arrayVariable()`	Suggests all array variables applicable in the current scope. For an example, see Live Templates in the iterations group.
`anonymousSuper()`	Suggests a supertype for a Kotlin object expression.
`сamelCase(String)`	Returns the string passed as a parameter, converted to camel case. For example, `my-text-file`/`my text file`/`my_text_file` will be converted to `myTextFile`.
`capitalize(String)`	Capitalizes the first letter of the name passed as a parameter.
`capitalizeAndUnderscore(sCamelCaseName)`	Capitalizes the all letters of a CamelCase name passed as a parameter, and inserts an underscore between the parts. For example, if the string passed as a parameter is`FooBar`, then the function returns `FOO_BAR`.
`castToLeftSideType()`	Casts the right-side expression to the left-side expression type. It is used in the iterationsgroup to have a single template for generating both raw-type and Generics Collections.
`className(sClassName)`	Returns the name of the current class (the class where the template is expanded).
`classNameComplete()`	This expression substitutes for the class name completion at the variable position.
`clipboard()`	Returns the contents of the system clipboard.
`camelCase(String)`	Returns CamelCase string out of snake_case string. For example, if the string passed as a parameter is `foo_bar`, then the function returns `fooBar`.
`complete()`	This expression substitutes for the code completion invocation at the variable position.
`completeSmart()`	This expression substitutes for the smart type completion invocation at the variable position.
`componentTypeOf (<array variable or array type>)`	Returns component type of an array. For example, see the Live Templates in theiterations group in the other group.
`currentPackage()`	Returns the current package name.
`date(sDate)`	Returns the current system date in the specified format. By default, the current date is returned in the default system format. However, if you specify date format in double quotes, the date will be presented in this format:
`decapitalize(sName)`	Replaces the first letter of the name passed as a parameter with the corresponding lowercase letter.
`descendantClassEnum(<String>)`	Shows the children of the class entered as a string parameter.
`enum(sCompletionString1,sCompletionString2,...)`	List of comma-delimited strings suggested for completion at the template invocation.
`escapeString(sEscapeString)`	Escapes the specified string.
`expectedType()`	Returns the type which is expected as a result of the whole template. Makes sense if the template is expanded in the right part of an assignment, after return, etc.
`fileName(sFileName)`	Returns file name with extension.
`fileNameWithoutExtension()`	Returns file name without extension.
`firstWord(sFirstWord)`	Returns the first word of the string passed as a parameter.
`groovyScript("groovy code")`	Returns Groovy script with the specified code. You can use `groovyScript` macro with multiple arguments. The first argument is a script text that is executed or a path to the file that contains a script. The next arguments are bound to `_1, _2, _3, ..._n` variables that are available inside your script. Also, `_editor` variable is available inside the script. This variable is bound to the current editor.
`guessElementType (<container>)`	Makes a guess on the type of elements stored in a `java.util.Collection`. To make a guess, IntelliJ IDEA tries to find the places where the elements were added to or extracted from the container.
`iterableComponentType(<ArrayOrIterable>)`	Returns the type of an iterable component, such as an array or a collection.
`iterableVariable()`	Returns the name of a variable that can be iterated.
`lineNumber()`	Returns the current line number.
`lowercaseAndDash(String)`	Returns lower case separated by dashes, of the string passed as a parameter. For example, the string `MyExampleName` is converted to `my-example-name`.
`methodName()`	Returns the name of the embracing method (where the template is expanded).
`methodParameters()`	Returns the list of parameters of the embracing method (where the template is expanded).
`methodReturnType()`	Returns the type of the value returned by the current method (the method within which the template is expanded).
`qualifiedClassName()`	Returns the fully qualified name of the current class (the class where the template is expanded). Clear the Shorten FQ names check box.
`rightSideType()`	Declares the left-side variable with a type of the right-side expression. It is used in theiterations group to have a single template for generating both raw-type and Generics Collections.
`snakeCase(sCamelCaseText)`	Returns snake_case string out of CamelCase string passed as a parameter.
`spaceSeparated(String)`	Returns string separated with spaces out of CamelCase string passed as a parameter. For example, if the string passed as a parameter is `fooBar`, then the function returns `foo bar`.
`subtypes(sType)`	Returns the subtypes of the type passed as a parameter.
`suggestIndexName()`	Suggests the name of an index variable. Returns `i` if there is no such variable in scope, otherwise returns `j` if there is no such variable in scope, etc.
`suggestVariableName()`	Suggests the name for a variable based on the variable type and its initializer expression, according to your code style settings that refer to the variable naming rules. For example, if it is a variable that holds an element within iteration, IntelliJ IDEA makes a guess on the most reasonable names, also taking into account the name of the container being iterated.
`suggestFirstVariableName(sFirstVariableName)`	Doesn‘t suggest `true, false, this, super`.
`time(sSystemTime)`	Returns the current system time.
`typeOfVariable(VAR)`	Returns the type of the variable passed as a parameter.
`underscoresToCamelCase(sCamelCaseText)`	Returns the string passed as a parameter with CamelHump letters substituting for underscores. For example, if the string passed as a parameter is `foo_bar`, then the function returns `fooBar`.
`underscoresToSpaces(sParameterWithSpaces)`	Returns the string passed as a parameter with spaces substituting for underscores.
`user()`	Returns the name of the current user.
`variableOfType(<type>)`	Suggests all variables that may be assigned to the type passed as a parameter, for example variableOfType("java.util.Vector"). If you pass an empty string ("") as a parameter, suggests all variables regardless of their types.
`JsArrayVariable`	Returns JavaScript array name.
`jsClassName()`	Returns the name of the current JavaScript class.
`jsComponentType`	Returns the JavaScript component type.
`jsMethodName()`	Returns the name of the current JavaScript method.
`jsQualifiedClassName`	Returns the complete name of the current JavaScript class.
`jsSuggestIndexName`	Returns a suggested name for an index.
`jsSuggestVariableName`	Returns a suggested name for a variable.

C标准中一些预定义的宏，如FILE，func等

C标准中一些预定义的宏 C标准中指定了一些预定义的宏,对于编程经常会用到.下面这个表中就是一些常常用到的预定义宏. 宏意义 __DATE__ 进行预处理的日期(“Mmm dd yyyy”形式的字符串文字) __FILE__ 代表当前源代码文件名的字符串文字 __LINE__ 代表当前源代码中的行号的整数常量 __TIME__ 源文件编译时间,格式微“hh:mm:ss” __func__ 当前所在函数名对于__FILE__,__LINE__,__func__这样的宏,在调试程序时是很有用的,因

（一）预定义宏、func、_Pragma、变长参数宏定义以及__VA_ARGS__

作为第一篇,首先要说一下C++11与C99的兼容性. C++11将对以下这些C99特性的支持都纳入新标准中: 1) C99中的预定义宏 2) __func__预定义标识符 3) _Pragma操作符 4) 不定参数宏定义以及__VA_ARGS__ 5) 宽窄字符串连接这些特性并不像语法规则一样常用,并且有的C++编译器实现也都先于标准地将这些特性实现,因此可能大多数程序员没有发现这些不兼容.但将这些C99的特性在C++11中标准化无疑可以更广泛地保证两者的兼容性.我们来分别看一下. 这次,

环境变量设置环境变量:1. export 变量名=变量值 2. 变量名=变量值 export 变量名 (export 变量名=变量值 :把该变量声明为环境变量,让这个SHELL中所有的子SHELL都能查看使用这个变量) 查询变量:env 查看进程树:pstree PATH:系统查找命令的路径 PATH=”$PATH”:/root/sh →PATH变量叠加(临时) 系统默认环境变量名都是大写位置参数变量 $n:n为数字,$0代表命令本身,$1-$9代表第一到第9个参数,10以上的参数用大括号包

c++IO之预定义格式控制

在C语言里,我们可以通过函数printf和scanf来进行格式化控制.而在C++中仍然包含了前者,但还提供了以下两种格式控制的方法:(1)使用流成员函数进行格式控制;(2)使用预定义操作符进行格式控制.下面我来一一介绍: 1.流成员函数主要是指ios类(流基类)中的,分别有: (1).设置状态标志流成员函数setf 一般格式:long ios::setf(long flags),调用格式:流对象.setf(ios::状态标志) ios类的状态标志有: 因为状态标志在ios类中定义为枚举值,所以在
