A new era of cross-platform application development: Learning Go language
With the rapid development of mobile devices and the diversification of user needs, cross-platform application development has become a hot trend in modern application development. Traditional application development methods often require independent development for different operating systems, but cross-platform development can greatly improve development efficiency and application coverage. Among the many cross-platform development tools and languages, the Go language is highly respected for its simplicity, efficiency and cross-platform capabilities.
Go language is a programming language developed by Google. It is famous for its simplicity and ease of understanding, efficient operation and excellent concurrency capabilities. It is designed to provide a way to develop reliable software quickly and seamlessly across multiple operating systems and hardware platforms. The following is an example that shows how to develop a cross-platform application using Go language.
package main import ( "fmt" "runtime" ) func main() { fmt.Printf("当前操作系统:%s ", runtime.GOOS) fmt.Printf("当前操作系统架构:%s ", runtime.GOARCH) }
In this example, we use the Go language's built-in library runtime
to obtain information about the current operating system and operating system architecture. By calling runtime.GOOS
and runtime.GOARCH
we can get the name and architecture of the current operating system respectively.
Before compiling and running the above code, we need to install the Go language development environment. You can download the Go installation package suitable for your operating system on the Go official website (https://golang.org/) and install it according to the official documentation.
After the installation is completed, we can use the terminal to enter the directory where the code is located, and run the following command to compile and run the program:
go build main.go // 编译程序 ./main // 运行程序
The running results will output information about the current operating system and operating system architecture. In this way, we can execute different logic according to different operating systems and process accordingly. This is useful for applications that need to run on different platforms.
In addition to simple cross-platform development, the Go language also provides many other features that can help developers better cope with the challenges of different platforms. For example, the concurrency model of the Go language uses Goroutines and Channels, making concurrent programming very simple and can easily handle a large number of requests and processing. In addition, the Go language has built-in powerful standard libraries that can be used for common tasks, such as network programming, data serialization, etc.
In short, learning the Go language has brought a new era to cross-platform application development. Its simplicity, efficiency, and cross-platform capabilities enable developers to develop applications faster and handle the differences between different platforms with ease. At the same time, the Go language also provides a powerful concurrency mechanism and a rich standard library, allowing developers to better face complex application scenarios. If you are interested in cross-platform application development, you may wish to learn and try to use Go language to develop applications. I believe it will bring you a new development experience.

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go uses the "encoding/binary" package for binary encoding and decoding. 1) This package provides binary.Write and binary.Read functions for writing and reading data. 2) Pay attention to choosing the correct endian (such as BigEndian or LittleEndian). 3) Data alignment and error handling are also key to ensure the correctness and performance of the data.

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.

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),
