golang comment newline

Golang comment line wrapping is a simple but important issue, especially in code reading and maintenance. When writing code, comments are a great way to make it clear what your code does. Good comments make it easier for others to understand your code and help you organize and manage it better yourself.

So, how do we wrap lines when writing comments? Comments in Golang code need to follow certain line breaking rules, otherwise unnecessary difficulties may arise when reading and maintaining the code.

In Golang, comments are represented by // and / /, and multi-line comments use / /.

For example:

// 这是单行注释

/*
这是多行注释
第二行
第三行
*/

When we are writing comments, we will encounter situations where we need to wrap the line. At this time, we need to wrap the line at the appropriate position. However, directly using the Enter key to break lines in comments is not allowed.

Here are some notes:

1. In a single-line comment, you can use spaces or the Tab key to separate the comment content into multiple lines.

// 这是单行注释，我们可以在任意位置换行，但是需要使用空格或Tab键来进行分隔

2. In multi-line comments, you need to add an * sign at the beginning of each line.

/*
这是多行注释
* 第二行注释
* 第三行注释
*/

3. If you do not add * at the beginning of each line, it will be parsed as a single-line comment instead of a multi-line comment.

/*
这是多行注释，但是第二行缺少 * 号
第二行注释
第三行注释
*/

4. In multi-line comments, if you need to break a line, you need to add an * sign to the previous line, and then comment on the next line.

/*
这是多行注释
* 这是第二行注释
*/

In short, in Golang code, comments should be wrapped in a standardized way, and the corresponding symbols should be added at the beginning. This can avoid unnecessary difficulties in code reading and maintenance. Good comments make code easier to understand and maintain.
