From 5c32631cb72d51ce8b91802f58b840e2f482d05f Mon Sep 17 00:00:00 2001 From: James Todd Gloyd Date: Fri, 23 Oct 2026 20:54:08 +0000 Subject: [PATCH 01/30] copilot-libraries: Add random stream generation module. Refs #766. Copilot does not currently contain any capability to produce a random stream of values. Randomization is useful for a lot of applications, from testing to fault injection. To make Copilot more versatile and useful for the use cases we want to support, we want to add a module to `copilot-libraries` with randomization primitives. This commit adds a new module that provides functions to produce random streams of different types and with different properties. --- copilot-libraries/copilot-libraries.cabal | 1 + .../src/Copilot/Library/Random.hs | 145 ++++++++++++++++++ 2 files changed, 146 insertions(+) create mode 100644 copilot-libraries/src/Copilot/Library/Random.hs diff --git a/copilot-libraries/copilot-libraries.cabal b/copilot-libraries/copilot-libraries.cabal index aa5c8e61..b34020a5 100644 --- a/copilot-libraries/copilot-libraries.cabal +++ b/copilot-libraries/copilot-libraries.cabal @@ -51,6 +51,7 @@ library , Copilot.Library.PTLTL , Copilot.Library.StateMachines , Copilot.Library.Statistics + , Copilot.Library.Random , Copilot.Library.RegExp , Copilot.Library.Utils , Copilot.Library.Voting diff --git a/copilot-libraries/src/Copilot/Library/Random.hs b/copilot-libraries/src/Copilot/Library/Random.hs new file mode 100644 index 00000000..d4828e12 --- /dev/null +++ b/copilot-libraries/src/Copilot/Library/Random.hs @@ -0,0 +1,145 @@ +{-# LANGUAGE DataKinds #-} +{-# LANGUAGE FlexibleContexts #-} +{-# LANGUAGE KindSignatures #-} +{-# LANGUAGE ScopedTypeVariables #-} +{-# LANGUAGE TypeFamilies #-} +{-# LANGUAGE TypeOperators #-} +-- | +-- Basic pseudo-random number generation. +-- +-- Information on performance of a selection of pseudo-random number generation +-- algorithms, including those implemented below, can be found at: +-- https://prng.di.unimi.it/ +-- +-- Important: these pseudo-random number generators are NOT cryptographically +-- secure generators. +module Copilot.Library.Random + ( randomW32 + , randomW64 + , boundedRandomIntegral + , proportionalRandomBool + , weightedRandomSelection + ) + where + +-- External imports +import Copilot.Language (Array, Stream, Typed, Word32, Word64, arrayElems, + constant, mod, mux, (!), (++), (.<<.), (.>>.), (.^.), + (<), (<=)) +import GHC.TypeLits (KnownNat, type (<=)) +import Prelude hiding (mod, (++), (<), (<=)) + +-- | Given two Word32 seeds, produce a pseudo-random stream of Word32 numbers, +-- which has a period of 2^32 - 1.
