How to convert C language software to Chinese interface

How to convert C language software into a Chinese interface requires specific code examples

With the development of globalization, more and more software developers are beginning to pay attention to Language support issues. For software developed using C language, converting the interface into Chinese is a common requirement. This article will introduce how to convert the interface of C language software into Chinese and provide specific code examples.

1. Modify string constants

First, we need to replace all English string constants in the program with Chinese versions. This includes menu names, button text, prompt messages, etc. These strings can be defined as macros and then called wherever needed.

#define MENU_FILE "File"
#define MENU_EDIT "Edit"
#define BUTTON_OK "OK"
#define BUTTON_CANCEL "Cancel"
Copy after login

Use the strings defined by these macros in the code to convert the text content of the interface into Chinese.

2. Set the locale to Chinese

In order to ensure that the program can correctly identify and display Chinese characters, we need to set the locale to Chinese during program initialization. You can use the following code to achieve this:

setlocale(LC_ALL, "zh_CN.UTF-8");
Copy after login

In this way, the program will process characters according to Chinese rules to ensure that the interface is displayed correctly.

3. Use the gettext() function for international support

In order to achieve multi-language support, it is recommended to use the gettext() function to manage strings in the program. By calling the gettext() function in the code, the string corresponding to the language version can be returned according to the current locale environment. First, you need to introduce the relevant header files into the program:

#include <libintl.h>
#include <locale.h>
Copy after login
Copy after login

Then, where text translation is required, use the gettext() function:

printf(gettext("Hello, world!
"));
Copy after login

4. Use the GNU gettext tool for translation

In order to facilitate the management of multi-language strings in the program, you can use the GNU gettext tool to generate and manage translation files. First, you need Include the following header files in your program:

#include <libintl.h>
#include <locale.h>
Copy after login
Copy after login

Then, use the gettext() function in the code, and use the xgettext tool to extract the strings that need to be translated and generate a .pot file. Next, you can generate a .po file based on the .pot file, which contains the corresponding Chinese translation. Finally, use the msgfmt tool to compile the .po file into a .mo file, and publish the .mo file together with the program.

5. Sample code

The following is a simple sample code that demonstrates how to convert the interface of a C language program into Chinese:

#include 
#include 
#include 
#include 

#define _(String) gettext(String)

int main() {
    setlocale(LC_ALL, "zh_CN.UTF-8");
    bindtextdomain("hello", "locale");
    textdomain("hello");

    printf(_("Hello, world!
"));
    
    return 0;
}
Copy after login

Through the above steps and sample codes, the interface of the C language software can be converted into Chinese. Hope these contents are helpful to you!
