How can I modify the appearance of folders in FileSystemProvider?

I have created an extension for vscode that includes a virtual filesystem with fake directories and files. While the extension is functioning properly, I am facing some challenges in customizing certain aspects due to lack of documentation.

1) I need to use forward slashes ('/') in directory names for a specific reason, but vscode automatically truncates it to only the last part after the last forward slash. Is there a way to display forward slashes in directory names as intended?

2) I have noticed that various code formatting extensions are able to add additional symbols and small text to files and directories in FileSystemProvider. For example, tslint changes the color of a filename when there are issues in the file and displays the number of issues as right-aligned text. Is there any documentation on how to achieve this in an extension? How can I implement similar features?

3) Is there a way to add a custom icon in front of directories and files within the extension?

Answer №1

Sharing my discovery regarding "How to customize icons for directories/files within VSCode". Despite the absence of this information in the official documentation, it can be found in vscode patch notes. You can actually personalize icons by modifying the iconTheme settings and assigning either a png/svg image or a character from a font as an icon:

package.json

"contributes": {
  "iconThemes": [
    {
      "id": "customthingy",
      "label": "CustomThingy",
      "path": "./config/custom-icon-theme.json"
    }
  ]
}

config/custom-icon-theme.json

{
    "fonts": [
        {
            "id": "someId",
            "src": [
                {
                    "path": "./someFont.ttf",
                    "format": "ttf"
                }
            ],
            "weight": "normal",
            "style": "normal",
            "size": "150%"
        }
    ],
    "iconDefinitions": {
        "_file": {
            "fontCharacter": "F",
            "fontId": "someId",
            "fontColor": "#F00"
        },
        "_file_special": {
            "fontCharacter": "X",
            "fontId": "someId",
            "fontColor": "#F00"
        },
        "_folder": {
            "iconPath": "./someIcon.svg"
        },
        "_folder_expanded": {
            "iconPath": "./someOtherIcon.png"
        }
    },
    "file": "_file",
    "folder": "_folder",
    "folderExpanded": "_folder_expanded",
    "folderNames": {
        ".vscode": "_vscode_folder",
    },
    "fileExtensions": {
        ".thing": "_file_special",
    },
    "fileNames": {
        "specialFile": "_file_special"
    }
}

Furthermore, remember to select the customized icon theme in your preferences.
