Custom Rules

Define project-specific regex rules in .revet.toml — no Rust code needed. Prefix: CUSTOM-

Basic rule

[[rules]]
id = "no-console-log"
pattern = 'console\.log'
message = "console.log should not be used in production code"
severity = "warning"
paths = ["*.ts", "*.js", "*.tsx"]
suggestion = "Use the logger utility instead"

With auto-fix

Add fix_find and fix_replace to enable revet review --fix support:

[[rules]]
id = "no-console-log"
pattern = 'console\.log'
message = "console.log should not be used in production"
severity = "warning"
paths = ["*.ts", "*.js"]
suggestion = "Use the logger utility instead"
fix_find    = 'console\.log\('   # regex matched on the line
fix_replace = 'logger.info('     # replacement string
