It is not difficult to make a VS Code theme by yourself, just follow a few key steps to complete it. 1. Preparation: Install Visual Studio Code, Yeoman and vscode-generator-code, run the command to create a new theme project and select the basic style; 2. Customize the color: Modify the color configuration items in the .json file such as background color and foreground color, and preview the effect in real time; 3. Adjust syntax highlighting: Define the color rules of different code elements through the .tmTheme file, and use tools to assist in generating or copying existing files to adjust; 4. Publish and share: Use the vsce command to package it into a .vsix file, which can be uploaded to the plug-in market or shared directly with others to install and use.

Want to make a VS Code theme yourself? Actually, it’s not that difficult, just figure out a few key steps. A theme is essentially a set of color and syntax highlighting definitions that you can start from scratch or modify on existing themes.

1. Preparation: Install the tools and understand the structure

Install Visual Studio Code and Yeoman (a scaffolding tool), as well as the vscode-generator-code generator. Open the terminal and execute the following lines of command:

• npm install -g yo generator-code

After installation, run:

• yo code

This process will allow you to choose which type of extension to create, just select "New Theme". Next it will ask you whether you want a dark or light color basic theme, just choose a starting point you like.

After generation, you will get a basic project structure with several core files:

• package.json : meta information and configuration of the topic
• themes/your-theme.json : actual color definition
• There may be .tmTheme file in syntax/ directory, which is used to control syntax highlighting.

2. Custom color: start with the basic color matching

Open the .json file you generated and you will find that there are a bunch of color settings, such as "editor.background" , "editor.foreground" , etc. These are the main color styles of the entire editor.

You can refer to the color theme definition reference in the official document to see what each field does. It is recommended not to be too greedy at the beginning. First, adjust the common settings, prospects, keywords, and annotations to see the effect.

For example:

 {
  "name": "My Custom Theme",
  "type": "dark",
  "colors": {
    "editor.background": "#1e1e1e",
    "editor.foreground": "#d4d4d4"
  }
}

After the modification, run npm run compile in the project directory, then open the project with VS Code, press F5 to preview your theme.

3. Adjust syntax highlighting: Make the code look more comfortable

If you want different colors of keywords, strings, function names, etc. in different languages, you need to deal with the syntax highlighting part. This part is a little more complicated because the .tmTheme format of TextMate is used.

You can use online tools (such as ThemeKit or VSCode Theme Generator ) to help you generate .tmTheme file, or directly copy an existing theme file and make adjustments a little bit.

Syntax highlighting rules are usually matched according to regular matches. For example, if you want to turn all comments into green, you can write them like this:

 <dict>
  <key>name</key><string>Comment</string>
  <key>scope</key><string>comment</string>
  <key>settings</key>
  <dict>
    <key>foreground</key><string>#6a9955</string>
  </dict>
</dict>

This part is more suitable for people with some front-end or development experience, but as long as you are willing to toss and adjust slowly, you can achieve results.

4. Publish and share: Let your topic be used by others

When you feel it's almost done, you can package it and publish it. Run the vsce package command to generate the .vsix file, which is a plug-in package that can be installed directly.

If you want to upload to the VS Code plug-in market, go to marketplace.visualstudio.com to register an account, and then use vsce publish to push it up.

Of course, you can also send it directly to others to download and install. They just need to click on the .vsix file and then run Extensions: Install from VSIX in VS Code.

Basically these steps. The whole process is not complicated, but some details are easy to ignore, such as whether the color contrast is appropriate, whether some language support is missing, whether the icon theme should be adapted together, etc. But as long as you do it step by step, it is absolutely fine to create your own VS Code theme.
