Felix: an Agda category theory for denotational design

Introduction

This library replaces the overgrown denotational-hardware library, which had mixed general category theory with some functionality for hardware design.

Dependencies

• Agda compiler. Works with Agda 2.6.4.
• The Agda standard library (agda-stdlib). Works with agda-stdlib 2.0.
• Haskell ieee754 package (as described under Troubleshooting below).

Troubleshooting

You might see an error message like this:

Calling: ghc -O -o /Users/sseefried/code/agda-machines/Test -Werror -i/Users/sseefried/code/agda-machines -main-is MAlonzo.Code.Test /Users/sseefried/code/agda-machines/MAlonzo/Code/Test.hs --make -fwarn-incomplete-patterns -fno-warn-overlapping-patterns
[  1 of 153] Compiling MAlonzo.RTE      ( MAlonzo/RTE.hs, MAlonzo/RTE.o )
Compilation error:

You can fix this error with:

cabal install --lib ieee754
