history

Project history and usage

Akku.scm is a project-based package manager for R6RS and R7RS Scheme. It gives Scheme projects a manifest, a lockfile, a local dependency environment, package publishing, and an index of portable Scheme libraries.

Project history

The GitLab project metadata dates the public repository to June 2018, while the release stream documented by GitLab includes earlier tagged releases and the 1.0 series in 2019. The manpage credits Akku's dependency solver lineage to Andreas Rottmann's dorodango, an earlier R6RS package manager whose solver was ported from aptitude.

Akku's early design centered on making portable Scheme code behave more like modern language-package ecosystems: projects declare direct dependencies in `Akku.manifest`, lock exact transitive dependency sources in `Akku.lock`, and activate an `.akku/env` shell where installed libraries and programs are placed on the right paths.

Adoption history

Akku serves a niche but real Scheme packaging audience. The README documents support for GNU/Linux, macOS, FreeBSD, Cygwin, OpenBSD, and MSYS2, and lists many Scheme implementations whose load paths can be populated from an Akku project.

Release notes show the project expanding beyond a basic R6RS manager: v0.5.0 began mirroring R7RS libraries from Snow, v1.0.0 moved release builds to autotools for portability, and v1.1.0 added features aimed at system package managers such as dpkg and rpm.

How it is used

Typical use is `akku init`, `akku list`, `akku install <pkg>`, then `.akku/env` to run in an environment where Scheme libraries and programs from the project are visible. Existing projects can add `Akku.manifest` and `Akku.lock` without starting from a template.

For publishing, Akku can scan packages, solve dependencies, verify signed package index data, and create package metadata. The manpage recommends committing both the manifest and lockfile for repeatable development.

Why package nerds care

Akku is package-nerd catnip because it applies familiar package-manager machinery to Scheme, a language family with many implementations and historically fragmented library paths.

The lockfile, signed index keys, local cache, R7RS-to-R6RS translation, and system-package-manager features make it more than a downloader. It is an attempt to bridge language packages, implementation compatibility, and OS packaging.
