How to set git encoding

With the widespread use of version control tools in recent years, Git has become one of the indispensable tools for developers. As an excellent version control tool, Git's wide application also improves programming efficiency and code maintainability. However, we often encounter some problems when using Git. One of the common problems is encoding problems. This article will focus on how to set up Git coding to help everyone use Git better.

1. Git encoding issues

Git encoding issues are mainly manifested in two aspects: file name encoding and text file encoding. Among them, file name encoding mainly refers to the problem that the file name may contain non-ASCII characters. Under Windows systems, file names are encoded in GBK by default, while under Linux and MacOS systems, they are encoded in UTF-8. When we use Git for version control, if different encoding systems or differently encoded file names are used, there may be a problem that the file name or path cannot be parsed correctly.

Text file encoding refers to the issue of character encoding in text files. In different encoding formats, the same characters may be stored as different binary code values, which may cause garbled characters when files are opened in different systems or software. In Git, if the encoding format of the text file does not match the system environment, garbled characters will also occur during operations such as viewing and editing.

2. Set the file name encoding

To address the file name encoding problem, we need to set the core.quotepath configuration parameter of Git. This parameter is used to determine whether to encode the file path. Under Windows systems, the default value of this parameter is true, which forces encoding of file names. However, under Linux and MacOS systems, the default value of this parameter is false, that is, the file name is not encoded. Therefore, if we share code between Windows systems and Linux/MacOS systems, we need to pay attention to setting this parameter.

We can use the following command to set this parameter:

git config --global core.quotepath false

If you need to restore the default settings, you can use the following command:

git config --global core.quotepath true

3. Set the text file encoding

When setting the text file encoding, we need to pay attention to two aspects: global settings and individual file settings.

1. Global settings

We can set the global default text file encoding by setting the git config parameter of Git. In Git, there are two relevant parameters: core.autocrlf and core.safecrlf.

core.autocrlf parameter is used to control the conversion of newline characters. The default text file newline character is CRLF on Windows and LF on Linux and MacOS. When adding or modifying a text file in Git, if this parameter is set to true, Git will convert the CRLF in the file to LF and store it, and when the file is checked out from Git, the LF in the file will be converted to CRLF. If this parameter is set to input, the newline character LF is forced.

We can use the following command to set this parameter:

git config --global core.autocrlf true

Or:

git config --global core.autocrlf input

The core.safecrlf parameter is used to check the encoding format of the text file. When this parameter is set to true, Git will check whether the newline characters in the file are correct. If there is a problem with the newline characters in the file, it will prevent the file from being submitted. We can use the following command to set this parameter:

git config --global core.safecrlf true

2. Single file settings

If we need to make special encoding settings for a certain text file, we can set it in the file Add the .gitattributes file to the Git repository where it is located and configure it in the file. In the .gitattributes file, we can specify the file name and file path pattern for each file, and specify the corresponding text attributes and encoding format. It should be noted that the .gitattributes file must be encoded in UTF-8.

For example, the following configuration can specify UTF-8 encoding for PHP files:

*.php  text encoding=utf-8

It should be noted that when setting the encoding of a single file, if the file has been added to Git, You need to delete the file from Git first, and then set the encoding again.

4. Summary

Through the above introduction, we can see that the encoding problem of Git depends on the encoding format of the system environment on the one hand, and the specific file encoding on the other hand. Format. In order to better use Git, we need to understand these coding-related issues and make appropriate settings according to the actual situation. This article mainly introduces solutions to Git coding problems and hopes to be helpful to readers.
