Compile

Use sing-box rule-set compile [--output <file-name>.srs] <file-name>.json to compile source to binary rule-set.

Fields

version

==Required==

Version of rule-set, one of 1 or 2.

• 1: Initial rule-set version, since sing-box 1.8.0.
• 2: Optimized memory usages of domain_suffix rules.

The new rule-set version 2 does not make any changes to the format, only affecting binary rule-sets compiled by command rule-set compile

Since 1.10.0, the optimization is always applied to source rule-sets even if version is set to 1.

It is recommended to upgrade to 2 after sing-box 1.10.0 becomes a stable version.

rules

==Required==

List of Headless Rule.
