Comment Lines is one of the source-code metrics Understand computes across 17+ languages — browse them in the GUI, export and track them, or script them with the Python API.
Comment Lines
API ID: CountLineCommentAlso Known As: Comment Lines of Code (CLOC)
Languages: Ada, Assembly, Basic, C#, C++, Fortran, Java, Jovial, Pascal, Python, Rust, VHDL, Web
Targets: Architectures, Classes, Files, Functions, Modules, Packages, Project, Subprograms
Number of lines containing comment.
This can overlap with other code counting metrics. For instance:
int j = 1; // comment
has a comment, is a source line, is an executable source line, and is a declarative source line.
Also known as Comment Lines of Code (CLOC).

- This metric can be disabled from "Project Configuration/Metrics/Lines and Statements" with the "Show line count metrics" option.
- This metric can be disabled from "Project Configuration/Metrics/Lines and Statements" with the "Include inactive lines" option for languages that have inactive lines.
- For projects and architectures, this metric is enabled from "Project Configuration/Metrics/Projects and Architectures" with the "Show default summary metrics" option.
