    • Package Flags

      dump-core
       (off by default)

      Write GHC core output.

      debug
       (off by default)

      Enable debug printing. This makes Agda slightly slower, and building Agda slower as well. The --verbose=N option only has an effect when Agda was built with this flag.

      debug-serialisation
       (off by default)

      Enable debug mode in serialisation. This makes serialisation slower.

      debug-parsing
       (off by default)

      Enable debug mode in parsing. This makes parsing slower.

      enable-cluster-counting
       (off by default)

      Enable the --count-clusters flag. (If enable-cluster-counting is False, then the --count-clusters flag triggers an error message.)

      optimise-heavily
       (on by default)

      Enable some expensive optimisations when compiling Agda.

      use-xdg-data-home
       (off by default)

      Install data files under $XDG_DATA_HOME/agda/$AGDA_VERSION by default instead of the installation location defined by Cabal. This should not be enabled in declarative build environments like Nix or Guix.

Agda is a dependently typed functional programming language: It has inductive families, which are similar to Haskell's GADTs, but they can be indexed by values and not just types. It also has parameterised modules, mixfix operators, Unicode characters, and an interactive Emacs interface (the type checker can assist in the development of your code).

Agda is also a proof assistant: It is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Rocq (formerly known as Coq), Idris, Lean and NuPRL.

This package includes both a command-line program (agda) and an Emacs mode.
