active's Introduction

This package defines an Active abstraction for time-varying values with finite start and end times. It is used for describing animations within the diagrams framework.

To install,

cabal install active

active's Issues

Test failure with QuickCheck-2.14.3

Seems new generator behavior in QuickCheck-2.14.3 reveals an issue in the test suite:

Image links in haddock are broken

All the image links in the haddock documentation of the active package [1] are broken.
Could you please fix the links? Thank you

`|>>` does not behave as I expect

runActive (interval 1 2 |>> interval 1 2) 3

is 2.0 instead of the expected 1.0

I made a revision of 0.2.0.15 to allow GHC 9.2

See https://hackage.haskell.org/package/active-0.2.0.15/revisions/

Support vector-space 0.9

The current version of active on hackage doesn't allow vector-space 0.9.

clampBefore and clampAfter are undefined

Whoops!

Test suite weirdness on arm64 and s390x

Hi,

I observe test failures on arm64 and s390x:
https://buildd.debian.org/status/fetch.php?pkg=haskell-active&arch=arm64&ver=0.2.0.4-1&stamp=1442017124
https://buildd.debian.org/status/fetch.php?pkg=haskell-active&arch=s390x&ver=0.2.0.4-1&stamp=1442020102
while the test suite goes through on other, similar architectures, including mipsel, powerpc and powerpc64, so there is no obvious pattern here.

The build is killed with a timeout after 150 minutes – is there anything in the testsuite that can deadlock on a non-threaded runtime? (Hoping this is not just haskell/cabal#2398 again, but then it would fail on other architectures with a non-threaded runtime, I’d say.)

ghc-8.10.3
base-4.14.1.0
QuickCheck-2.14.2

If you can make this change and release a new revision on hackage, it will allow us to better package this in gentoo.

build fails with lens-4.15.2
