It is both a language-runtime package and a proof-assistant package, with an interactive editor workflow and a library system based on .agda-lib files. ### Project history The official history page traces the lineage back to proof assistants based on Martin-Lof type theory developed in Gothenburg since 1983, followed by intensional dependent type theory systems around 1990 such as ALF. In the mid-1990s, prototypes and redesigns explored theory mechanisms, proof editors, and type checking with metavariable constraints. The original Agda, now often called Agda 1, was implemented in Haskell by Catarina Coquand. In 2004 the Programming Logic Group began collaborating with AIST in Japan, and the Agda Implementors Meetings started as biannual meetings alternating between Sweden and Japan. Work on the current Agda system began after the 2005 AgdaLight prototype by Ulf Norell and Andreas Abel. Ulf Norell's 2007 thesis, 'Towards a practical programming language based on dependent type theory', is named by the official history page as a main reference for Agda 2. ### Adoption history Agda's adoption has grown through academic type theory, dependently typed programming, proof engineering, and formalized mathematics communities. The official wiki says the center of development is the Logic and Types group at Chalmers and Gothenburg University, while GitHub metadata shows a broad open-source contributor base. As a package, Agda is visible across Haskell and OS package ecosystems. The README links Hackage and Stackage badges, the official installation docs describe binary releases, source builds with cabal and Nix, and a Python installer, and the supplied batch facts list Homebrew, Debian, Fedora, Nix, Arch, and Ubuntu. ### How it is used Users run agda to type-check files, use agda-mode or another editor integration for interactive development, and manage libraries through .agda-lib files plus AGDA_DIR/libraries and AGDA_DIR/defaults files. On Unix-like systems AGDA_DIR defaults to ~/.config/agda, with fallback behavior for ~/.agda; on Windows it defaults under AppData/Roaming/agda. Agda code often depends on the standard library but the official installation page notes that the standard library is not necessarily bundled with every Agda distribution. The package-system documentation therefore matters to packagers and users because it defines how installed libraries become visible to the type checker. ### Why package nerds care Agda is one of those packages where the executable is only half the story: editor integration, Unicode input, library metadata, GHC compatibility, data files, standard-library versioning, and release notes all affect whether users can actually type-check projects. The 2.8.0 release notes are especially package-relevant because they say Agda became a self-contained single binary and mention behavior around data files and library builds. That kind of upstream packaging change directly affects formulae, distro packages, and reproducible development environments. ### Timeline - 1983: Gothenburg work on Martin-Lof type theory proof assistants begins. - 1990: ALF lineage of intensional dependent type theory systems begins around Gothenburg. - 2004: Agda collaboration with AIST begins and Agda Implementors Meetings start. - 2005: AgdaLight prototype work begins, leading toward Agda 2. - 2007: Ulf Norell thesis on a practical dependently typed programming language published. - 2025: Agda 2.8.0 released. ### Related projects - ALF is the earlier Gothenburg logical framework named in the official history. - AgdaLight is the 2005 prototype named as a direct precursor to Agda 2. - The Agda standard library is a separately versioned library package used by many Agda projects. - Rocq, Epigram, Matita, and NuPRL are listed by the official wiki as related dependent-type proof assistants. ### Sources - - - - - - source_facts.package-manager ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
