Agda: A dependently typed functional programming language and proof assistant

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

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 Coq, Idris, Lean and NuPRL.

This package includes both a command-line program (agda) and an Emacs mode. If you want to use the Emacs mode you can set it up by running agda-mode setup (see the README).

Note that the Agda package does not follow the package versioning policy, because it is not intended to be used by third-party packages.

Flags

Manual Flags

Name	Description	Default
debug	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.	Disabled
debug-serialisation	Enable debug mode in serialisation. This makes serialisation slower.	Disabled
debug-parsing	Enable debug mode in parsing. This makes parsing slower.	Disabled
enable-cluster-counting	Enable the --count-clusters flag. (If enable-cluster-counting is False, then the --count-clusters flag triggers an error message.)	Disabled
optimise-heavily	Enable some expensive optimisations when compiling Agda.	Disabled
