Clash Verge Rev Override Tutorial: Customize Rules Like a Pro

Introduction to Clash Verge Rev Overrides

Clash Verge Rev has rapidly become the premier desktop client for proxy management, powered by the highly efficient mihomo core. However, relying solely on imported subscription profiles limits your control. When your provider updates the subscription, any manual tweaks you made directly to the YAML file are instantly overwritten. This is where clash verge rev overrides become indispensable.

Overrides allow you to apply custom configurations, rules, and scripts on top of your base subscription dynamically. They ensure your personalized settings survive subscription updates, giving you the flexibility to route specific traffic, tweak DNS resolution, and inject custom proxy groups without ever touching the original subscription file. In this tutorial, we will dive deep into the mechanics of overrides and show you how to customize your setup like a true professional.

Understanding the Three Override Types

Clash Verge Rev provides three distinct types of override profiles, each serving a specific purpose in your configuration pipeline. Understanding when to use each type is crucial for maintaining a clean and efficient setup.

Merge Profile

The Merge profile utilizes YAML deep-merge semantics. It takes your custom YAML configuration and overlays it onto the base subscription. If a key exists in both, the merge profile's value typically takes precedence, or arrays are appended depending on the core's implementation. This is the safest and most common method for adding static rules, modifying DNS settings, or appending proxy groups.

Script Profile

For dynamic and complex transformations, Script profiles are the way to go. Clash Verge Rev supports both JavaScript and Lua. The script receives the parsed base configuration as an object, allowing you to iterate through arrays, conditionally inject rules based on node names, or completely restructure proxy groups before the core loads the config.

Global Profile

The Global profile completely replaces the base subscription configuration. This is rarely used for daily driving because it defeats the purpose of subscription updates, but it is highly useful for testing entirely custom configurations or running a standalone local proxy setup without any external subscriptions.

Step-by-Step: Creating a Merge Profile

Let us start with the most straightforward override method. We will create a Merge profile to inject a custom routing rule and enforce a specific DNS configuration.

rules:
  - DOMAIN-SUFFIX,internal-corp.com,DIRECT
  - DOMAIN-SUFFIX,secure-bank.com,Proxy

dns:
  enable: true
  enhanced-mode: fake-ip
  fake-ip-range: 198.18.0.1/16
  nameserver:
    - https://dns.alidns.com/dns-query
  fallback:
    - https://dns.cloudflare.com/dns-query

Step-by-Step: Writing JavaScript Script Profiles

When you need to manipulate the configuration based on the actual nodes provided by your subscription, a Script profile is required. We will write a JavaScript function to automatically group all nodes containing the word 'Japan' into a dedicated proxy group.

function main(config) {
  // Filter proxies that contain 'Japan' or 'JP' in their name
  const japanNodes = config.proxies.filter(
    p => p.name.includes('Japan') || p.name.includes('JP')
  );

  if (japanNodes.length > 0) {
    // Create a new proxy group
    const japanGroup = {
      name: 'Japan Auto',
      type: 'select',
      proxies: japanNodes.map(p => p.name)
    };

    // Inject the group at the beginning of the proxy-groups array
    config['proxy-groups'].unshift(japanGroup);

    // Add a rule to route specific traffic to this new group
    config.rules.unshift('DOMAIN-SUFFIX,anime-streaming.jp,Japan Auto');
  }

  return config;
}

Advanced Rule Injection and Traffic Splitting

Mastering overrides allows you to implement sophisticated traffic splitting strategies that go far beyond basic geo-IP routing. By combining Merge profiles with external rule providers, you can maintain highly granular control over your network traffic.

Instead of hardcoding hundreds of domains, you can inject RULE-SET directives via overrides. This keeps your configuration clean and allows you to update rules independently. For a comprehensive breakdown of how to structure these rules and implement split routing for different applications, refer to our detailed Clash Split Routing Rules Guide.

Here is how you inject a remote rule-set via a Merge profile:

rule-providers:
  custom-ads:
    type: http
    behavior: domain
    url: 'https://raw.githubusercontent.com/example/rules/main/ads.yaml'
    path: ./ruleset/ads.yaml
    interval: 86400

rules:
  - RULE-SET,custom-ads,REJECT

Finally, always conclude your injected rules with a MATCH directive if you are completely rewriting the rules array via a script, or ensure your Merge profile appends rules correctly so the default fallback at the end of the subscription remains intact. Misplacing the fallback rule is a frequent cause of traffic leaks.

Modifying DNS and Sniffer Settings via Overrides

The mihomo core includes a powerful sniffer that can analyze raw traffic to determine the actual domain being accessed, bypassing IP-based routing limitations. However, default sniffer settings might conflict with certain local network setups. You can override these settings to fine-tune performance and compatibility.

sniffer:
  enable: true
  sniff:
    HTTP:
      ports: [80, 8080]
    TLS:
      ports: [443, 8443]
    QUIC:
      ports: [443, 8443]
  skip-domain:
    - 'Mijia Cloud'
    - '+.apple.com'

dns:
  enable: true
  listen: '0.0.0.0:1053'
  ipv6: false
  default-nameserver:
    - 223.5.5.5
    - 119.29.29.29
  nameserver:
    - 'https://doh.pub/dns-query'
  fallback:
    - 'https://dns.google/dns-query'
  fallback-filter:
    geoip: true
    geoip-code: CN

Troubleshooting Common Override Errors

Even with the best intentions, syntax errors or logical flaws in your overrides can cause the mihomo core to fail to start. When Clash Verge Rev fails to load the configuration, it usually points to an issue in the override chain.

The most common errors include invalid YAML indentation in Merge profiles and undefined proxy group names in rules. If a rule points to a group that does not exist, the core will crash. To debug this, switch to the Runtime tab in Clash Verge Rev. This tab shows the final, merged configuration that is actually sent to the core. Compare it against your expectations to spot missing keys or malformed arrays.

If you are struggling with basic rule syntax or proxy group definitions before even attempting overrides, it is highly recommended to review the foundational concepts in our Clash Rule Configuration Tutorial first.

Best Practices for Maintaining Your Overrides

As your configuration grows, managing multiple overrides can become chaotic. Adopting a structured approach will save you hours of debugging in the long run.

Furthermore, keep your JavaScript scripts clean and well-commented. Use descriptive variable names and avoid hardcoding node names whenever possible; rely on pattern matching instead. For advanced users, consider storing your override scripts and merge YAML files in a local Git repository. You can then use the 'Local File' option when creating a new profile in Clash Verge Rev, pointing directly to your version-controlled files. This allows you to track changes, revert broken configurations instantly, and share your sanitized override setups with the community without exposing your actual subscription links.

Finally, regularly review your Clash Verge Rev Tips & Hidden Features to discover new client updates that might introduce native UI features, potentially eliminating the need for complex script overrides. By mastering clash verge rev overrides, you transform a simple proxy client into a highly customized, resilient network gateway tailored exactly to your workflow.
