Description

Detect Repeated Regex Compilations

This rule detects cases where the same regex pattern is compiled multiple times within the same function. This pattern can lead to performance degradation and unnecessary memory usage.

Detection Mechanism

1. AST Analysis
2. Function-level Inspection:
   • Examines each function declarations (ast.FuncDecl) individually.
3. Regex Compilation Call Identification:
   • Locates calls to regex.Compile or regexp.MustCompile functions.
4. Pattern Tracking:
   • Stores the pattern string of each compile call in a map.
5. Duplication Detection:
   • Simple map check. if the same pattern already exists in the map, it's considered a duplicated compilation.
