| Purpose | LXR indexes and cross-references source code for web browsing, linking identifiers to their definitions and uses. | The product interactively searches large source-code bases using language structure instead of only literal text matching. |
| Support | The project directs users to its forum and trackers to contact developers and report issues. | The maker provides [email protected] for inquiries and says custom scanners can be built for unusual languages, dialects, or structured text. |

Semantic Designs Source Code Search Engine
Semantic Designs Source Code Search Engine searches and inspects indexed code using language structure, so queries can target constructs and complex statements as well as text patterns. It supports regular expressions and numeric values or ranges, and searches can disregard whitespace, line breaks, and comments. The maker says it can search millions of lines across tens of thousands of source files. Results include surrounding code and highlighted matches; users can open source text or launch an editor on the matching file. The engine also calculates Cyclomatic and Halstead complexity metrics and counts source, code, comment, and blank lines. Listed scanners include ABAP, C, C++, COBOL, Java, JavaScript, Python, PHP, SQL dialects, and XML, with beta scanners and custom options. Files are collected, scanned, and indexed on a recurring schedule. Results can be produced in XML for other graphical interfaces. The free evaluation covers 10,000 lines and requires registration; its license ends 90 days after download. Pricing for a production license is available on request.
