## プロジェクトの歴史と使われ方

libdivecomputer is a cross-platform C library and utility set for talking to dive computers over serial, USB, USB HID, IrDA, Bluetooth Classic, and Bluetooth Low Energy transports. Its official site frames it as an open source compatibility layer across many dive-computer manufacturers rather than as an end-user dive log application.

### プロジェクトの歴史

The project grew around the practical problem of extracting dive profiles from vendor-specific dive computers on Unix-like systems, Windows, mobile platforms, and BSDs. The repository README points to the libdivecomputer site and a SourceForge project page, reflecting the project's older open-source hosting history before GitHub became the main development surface.

The public tag history shows a 0.2.0 release in September 2012, followed by 0.3.0 in February 2013, 0.4.x in 2013-2014, 0.5.0 in September 2016, 0.6.0 in November 2017, 0.7.0 in May 2021, 0.8.0 in May 2023, and 0.9.0 in June 2025.

### 採用の歴史

libdivecomputer's adoption comes from being infrastructure: applications and scripts can use one library instead of maintaining per-device protocols for Aeris, Aqualung, Cressi, Mares, Oceanic, Shearwater, Suunto, Uwatec, and many other supported manufacturers. Homebrew, MacPorts, and Nix packaging make that hardware-support layer easy to install for developers and technically inclined divers.

### 使われ方

The documentation describes a conventional autotools build on Unix platforms and points users to a manual, manpages, examples, backend status, driver notes, roadmap material, and old API design discussions. The packaged `dctool` utility is the command-line face of the library for testing communication and retrieving data.

### パッケージ好きにとっての重要性

For package maintainers, libdivecomputer is interesting because it turns a messy hardware matrix into one LGPL library with optional platform transport details. It is the kind of package that quietly matters: most users meet it indirectly through dive-log software, but distribution packaging determines whether niche USB/Bluetooth dive-computer workflows work out of the box.
