How to escape paths in Golang

In Golang, path escaping is a very important topic. Because paths are represented differently in different operating systems. This requires us to perform certain escape operations on the path when writing code to ensure that the code can run normally in different operating systems.

In Golang, path escaping requires understanding the following two key points:

1. Path separator

In Windows systems, path separator The default is backslash (); on Unix-like systems (such as Mac OS and Linux), the path separator defaults to forward slash (/). Therefore, when writing code, you need to choose appropriate path separators according to different operating systems.

2. Special characters

In the path, there are some special characters (such as spaces, question marks, asterisks, etc.) that need to be escaped, otherwise it may cause program errors. In Golang, these special characters can be escaped using escape characters. The specific escape characters and the special characters they represent are as shown in the following table:

##\aBell character\ bBackspace character##\f\n##\rCarriage return characterTab characterVertical tabBackslashSingle quotesDouble quotesIn addition to the above two key points, we also need to pay attention to the following two precautions:

Escape Characters	Special characters
Form feed character
Line feed character
	##\t
	\v
	\
	\'
	\"
	##When actually writing code, we need to choose appropriate escape characters according to different scenarios.

Use the filepath package

The filepath package is provided in Golang to operate file paths. This package will automatically select the appropriate path separator according to the operating system. Therefore, when writing code , we should use the filepath package for path operations as much as possible, so as to avoid some potential errors.

1. Use absolute paths

When writing code, it is best to use Use an absolute path to specify the file path, which ensures that the code can still run normally in different directories. If you use a relative path, there may be a problem that the file cannot be found in different directories.

2. To sum up As mentioned above, path escaping is a very important topic in Golang. Correct path escaping can ensure that the code runs normally in different operating systems and avoid unnecessary errors. Therefore, when writing code, we should develop Good path escaping habits follow the above two key points and precautions.
