#13235: (makeVersion [4, 9, 0, 0] <= makeVersion [4, 9]) == False -------------------------------------+------------------------------------- Reporter: varosi | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: | Version: 8.0.1 libraries/base | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I have hit a strange bug in cabal project. Zeroes in Version have meaning, which is not logical (at least mathematically). See this example: {{{ import Data.Version makeVersion [4, 9, 0, 0] <= makeVersion [4, 9] False }}} I propose to add zeroes to the version with less numbers, so they could be equally compared.
