It was forked in 2024 from ligo-segments and is designed to represent time windows or ranges, with built-in operations for combining, querying, and manipulating collections of intervals. The package has no runtime dependencies and is marked Production/Stable, supporting Python 3.9 through 3.14.\n\nThe library is primarily used in gravitational-wave physics and astronomy research, where time-interval representation is fundamental. It offers a clean API for interval arithmetic without requiring external dependencies, making it lightweight for projects that need interval logic without heavy computational overhead.","worth_installing":"Yes, if you work with semi-open intervals or time windows in scientific or data-analysis code. The package is stable, dependency-free, and widely used in gravitational-wave research. Install friction is moderate due to compiled wheels, but pre-built binaries exist for common platforms. The copyleft license is a blocker only if you need to distribute proprietary code; for internal or open-source use, it poses no barrier. Maintenance is aging (207 days since last release), so verify active support if you need ongoing updates."},"id":"igwn-segments","links":{"html":"https://skillfed.io/packages/igwn-segments","md":"https://skillfed.io/packages/igwn-segments.md","pypi":"https://pypi.org/project/igwn-segments/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-01-19","license_spdx":null,"license_treatment":"copyleft","name":"igwn-segments","python_support":"supports_current","summary":"Representations of semi-open intervals"},"popularity":{"monthly_downloads":110456,"position":12460,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.1.1"}
