What is go languageJan 07, 2021 pm 03:38 PM
go language

Go language is a statically strongly typed, compiled language, and its syntax is similar to C language. Go language stipulates that there is no need to write a semicolon after the end of each line of program, braces cannot be placed on a new line, and if judgments and for loops do not need to be wrapped in parentheses.

Detailed introduction:

Go (also known as Golang) is the work of Robert Griesemer, Rob Pike and A statically strongly typed, compiled language developed by Ken Thompson. The Go language syntax is similar to C, but its functions include: memory safety, GC (garbage collection), structural form and CSP-style concurrent computing.

Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages ​​that adopt a similar model include Occam and Limbo, but it also has features of Pi operations, such as channel transmission. Plugin support is opened in version 1.8, which means that some functions can now be dynamically loaded from Go.

Compared with C, Go does not include functions such as enumeration, exception handling, inheritance, generics, assertions, virtual functions, etc., but it adds slice type, concurrency, pipes, garbage collection, Language-level support for features such as interfaces. The Go 2.0 version will support generics, but has a negative attitude towards the existence of assertions, and also defends that it does not provide type inheritance.

Unlike Java, Go has built-in associative arrays (also known as hash tables (Hashes) or dictionaries (Dictionaries)), just like string types.

Writing style:

There are several regulations in Go. When the following regulations are not matched, compilation will produce an error.

There is no need to write a semicolon (;) after each line of the program.

Braces ({) cannot be placed on new lines.

If judgments and for loops do not need to be wrapped in parentheses.

Go also has a built-in gofmt tool, which can automatically sort out excess whitespace in the code, align variable names, and convert aligned spaces into tabs.

go语言有没有缩进go语言有没有缩进Dec 01, 2022 pm 06:54 PM

go语言有缩进。在go语言中,缩进直接使用gofmt工具格式化即可(gofmt使用tab进行缩进);gofmt工具会以标准样式的缩进和垂直对齐方式对源代码进行格式化,甚至必要情况下注释也会重新格式化。

go语言为什么叫gogo语言为什么叫goNov 28, 2022 pm 06:19 PM

go语言叫go的原因:想表达这门语言的运行速度、开发速度、学习速度(develop)都像gopher一样快。gopher是一种生活在加拿大的小动物,go的吉祥物就是这个小动物,它的中文名叫做囊地鼠,它们最大的特点就是挖洞速度特别快,当然可能不止是挖洞啦。

tidb是go语言么tidb是go语言么Dec 02, 2022 pm 06:24 PM

是,TiDB采用go语言编写。TiDB是一个分布式NewSQL数据库;它支持水平弹性扩展、ACID事务、标准SQL、MySQL语法和MySQL协议,具有数据强一致的高可用特性。TiDB架构中的PD储存了集群的元信息,如key在哪个TiKV节点;PD还负责集群的负载均衡以及数据分片等。PD通过内嵌etcd来支持数据分布和容错;PD采用go语言编写。

go语言能不能编译go语言能不能编译Dec 09, 2022 pm 06:20 PM

go语言能编译。Go语言是编译型的静态语言,是一门需要编译才能运行的编程语言。对Go语言程序进行编译的命令有两种:1、“go build”命令,可以将Go语言程序代码编译成二进制的可执行文件,但该二进制文件需要手动运行;2、“go run”命令,会在编译后直接运行Go语言程序,编译过程中会产生一个临时文件,但不会生成可执行文件。

go语言是否需要编译go语言是否需要编译Dec 01, 2022 pm 07:06 PM

go语言需要编译。Go语言是编译型的静态语言,是一门需要编译才能运行的编程语言,也就说Go语言程序在运行之前需要通过编译器生成二进制机器码(二进制的可执行文件),随后二进制文件才能在目标机器上运行。

golang map怎么删除元素golang map怎么删除元素Dec 08, 2022 pm 06:26 PM

删除map元素的两种方法:1、使用delete()函数从map中删除指定键值对,语法“delete(map, 键名)”;2、重新创建一个新的map对象,可以清空map中的所有元素,语法“var mapname map[keytype]valuetype”。

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
