golang quote escape

When using strings in golang, we often need to use quotation marks to represent a string. However, in some cases, we need to use quotes in a string, in which case we need to use an escape symbol to escape the quotes.

In golang, we can use backslash () to escape, for example:

str := "This is a "quoted" string"

In the above example, we need to add quotes to the string, so we use The escape character is used to tell the compiler that the quotation mark is not the end of the string, but a character in the string.

Similarly, in another example, we use backslashes to escape newline characters:

str := "This is a
multi-line
string"

This string contains two newline characters, but golang will interpret these newline characters Interpreted as a string terminator, so we need to use a backslash to tell the compiler that these symbols should be treated as a character in the string.

In golang, in addition to quotation marks and newline characters, there are some other characters that need to be escaped, such as:

• : bell character
• : Backspace character
• : Form feed character
• : Carriage return character
• : Tab character
• : Vertical tab character

Of course, in some cases, we do not want to use escape characters, but want to output the characters as they are. In this case, we can use raw string, for example:

str := `This is a "quoted" string`

In this string, we have used backtick (`) to represent raw string. In this case, we don't need to use an escape character to escape the quotes because the entire string is treated as a raw string.

In short, when using strings in golang, we need to pay special attention to how to use escape symbols to escape certain characters. Of course, if we don't want to use escape symbols, we can use raw strings, which can make it easier to represent strings containing quotes and other special characters.
