The standard library aims to contain all the tools needed to easily write both programs and proofs. While we always try and write efficient code, we prioritise ease of proof over type-checking and normalisation performance. If computational performance is important to you, then perhaps try agda-prelude instead.

If you're looking to find your way around the library, its structure is described in the README.agda and the associated README folder. You can browse the library source code in glorious clickable html here.

See the instructions here for how to install version 1.1 of the standard library.

If you're using an old version of Agda, you can download the corresponding version of the standard library on the Agda wiki.

If you're using a development version of Agda rather than the latest official release you should use the experimental branch of the standard library rather than master. The experimental branch contains non-backwards compatible patches for upcoming changes to the language.

Most of the library can be type-checked using the --safe flag. Please consult GenerateEverything.hs for a full list of modules that use unsafe features.

Most of the library can be type-checked using the --without-k flag. Please consult GenerateEverything.hs for a full list of modules that use axiom K.

If you would like to suggest improvements, feel free to use the Issues tab. Even better if you would like to make the improvements yourself, we have instructions in HACKING to help you get started.
