Ventoy Menu Class Plugin

  • What is menu class

Ventoy use grub2's theme which has a class property in the menu. You can refer https://www.gnu.org/software/grub/manual/grub/grub.html for detail.
To be simply, you can define a class for the ISO files and show an icon in the boot menu. For example, you define a menu with class 'ubuntu' and put a ubuntu.png file in iconsdirectory under the theme directory. Then the icon can be shown in the menu as bellows:

  • Json Configuration

Recommend to use VentoyPlugson, a GUI ventoy.json configurator. Refer VentoyPlugson
A menu_class array is defined to describe the configuration in /ventoy/ventoy.json. Both image file and directory are supported.
Use key to specify a substring of the image file name and dir to specify the full path of a directory. 

{
    "menu_class": [
        {
            "key": "MX-",
            "class": "mx"
        },
        {
            "key": "ubuntu",
            "class": "ubuntu"
        },        
        {
            "key": "CentOS-7-",
            "class": "centos"
        },
        {
            "parent": "/ISO/Linux/Arch",
            "class": "arch"
        },
        {
            "dir": "/ISO/Linux",
            "class": "linux"
        }        
    ]
}

Key Type Description
key STRING The key string. Ventoy will do a substring match (case sensitive) with the ISO name and this key. If this key is a substring of the ISO name, then the ISO menu will use the class. Only name of the ISO file will be used for match (not the full path)
parent STRING The full path of a directory. Ventoy will use the class for all the image files under this directory and its subdirectories.
Attention: The trailing slash must be removed (For example /ISO/abc is right, /ISO/abc/ is wrong).
dir STRING The full path of a directory. Ventoy will do a full string match (case sensitive) and use the class if matched.
Attention: The trailing slash must be removed (For example /ISO/abc is right, /ISO/abc/ is wrong).
class STRING menu class string (max length: 128)
  1. The class has higher position with higher priority
  2. The match for the key is something like strstr(iso_name, key)
  3. If you have huge number of ISO files in USB and define a long menu_class array, it will take a little long time to load Ventoy's boot menu.
  4. You need to set item_spacing item_padding item_icon_space and other variables in theme.txt for better display (Grub2 theme tutorial)

Built-in Class Description
vtoyret All the return to previous menu will use this class
vtoydir If none of the item in menu_calss match, Ventoy will use it as the default class for directory.
vtoyiso If none of the item in menu_calss match, Ventoy will use it as the default class for ISO file.
vtoywim If none of the item in menu_calss match, Ventoy will use it as the default class for WIM file.
vtoyimg If none of the item in menu_calss match, Ventoy will use it as the default class for IMG file.
vtoyefi If none of the item in menu_calss match, Ventoy will use it as the default class for EFI file.
vtoyvhd If none of the item in menu_calss match, Ventoy will use it as the default class for VHD(x) file.
vtoyvtoy If none of the item in menu_calss match, Ventoy will use it as the default class for vtoy file.

  • Special Notes

All the submenus under F4 and F5 will inherit the built-in class of their parent menu. For example:
For F5 Tools ---> Check plugin json configuration (ventoy.json) --> Check theme plugin configuration
It has class of debug_theme debug_json and F5tool. So it will show debug_theme.png if exist or debug_json.png if exist or F5tool.png if exist.

  • Multi-Mode

Supported. You can set different configurations for different BIOS mode. Please refer Multi-Mode Option for details.
