MacBook is a very popular computer and is widely praised by users for its excellent performance. Golang is also a popular programming language at present. It has efficient compilation speed and concise syntax, so it is favored by developers. In this article, we will introduce how to install golang on MacBook.
Step 1: Download the installation package
First, we need to download the golang installation package from the official website. Open your favorite browser and enter the following URL:
https://golang.org/dl/
Select the version suitable for MacBook on the page, usually select the "MacOS" version . After the download is complete, open the downloaded installation package and follow the instructions to complete the installation.
Step 2: Configure environment variables
After the installation is completed, we need to configure the environment variables in the terminal so that we can use golang normally.
First, enter the following command in the terminal:
nano ~/.bash_profile
At this time, you will see an editor window, which is your bash configuration document. If nano is not installed on your MacBook, please install it yourself. In the editor, you need to add the following:
export PATH=$PATH:/usr/local/go/bin
This tells the system to add the golang executable file path to PATH environment variable, so that you can directly call golang commands in the terminal.
When finished, you press "ctrl o" on your keyboard to save the file and "ctrl x" to exit the editor.
Step 3: Test
Now that you have completed the installation and configuration of golang, let's test whether the installation is successful.
Open the terminal and enter the following command:
go version
If you see output similar to the following, you have successfully installed and configured golang:
go version go1.13.1 darwin/amd64
At this point, the installation and configuration of golang on MacBook has been completed.

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),
