lines

lines is a lightweight Go command-line tool built with Cobra that scans source files to find lines exceeding a specific visual width limit. It accurately handles tab characters and can automatically skip function signatures to prevent false positives on boilerplate code.

Features

• Tab Width Awareness: Measures tab characters (\t) based on their visual column size rather than a single character byte.
• AST Smart Filtering: Leverages Go's native syntax parser to identify and skip function signatures, anonymous functions, and function-typed struct fields.
• Fragmented Expression Detection: Identifies expressions (like multi-line calls, assignments, literals, or binary operations) that were broken down into multiple lines but could completely fit within a single line limit.
• Pipeline Friendly: Seamlessly accepts input from either a file argument or directly via standard input (stdin).
