[Haskell-cafe] ANN: package-vt-0.1.3.3, Haskell Package Versioning Tool

Hi! I'm pleased to announce the first release of my program package-vt. It's role is to detect changes between two versions of package that should cause version bump. Recommended versioning policy for Haskell packages is on the wiki [1]. The ultimate goal is to get as good approximation of the algorithm specified there as possible. Currently the tool is far from being complete: it only detects changes to exports in .cabal and module files, but doesn't take any types into consideration, not to mention other possible heuristics. This tool is not meant as a replacement for developer's own brain. It can only detect a subset of changes, and there will always be some important changes it won't catch, like adding such line: head (_:y:_) = y However, it can be used for some quality checks. Thing that needs improving is user interface. No options are currently accepted. This, and a lot more, will change in future versions. You can find a Git repo here [2]. The repo contains 'tests' directory with two useful scripts. You can use them to run package-vt on anything from Hackage. Here are a few random usage examples: 1) Detect small change within module package-vt packages/HCL/1.1/HCL-1.1/HCL.cabal packages/HCL/1.2/HCL-1.2/HCL.cabal Single changes: ChangeABC : Entity added to module ModuleName "HCL" --- EVar (UnQual (Ident "prompt1")) --- Biggest change comes from: ChangeABC : Entity added to module ModuleName "HCL" --- EVar (UnQual (Ident "prompt1")) 2) Detect new module added to .cabal package-vt 0.2.0/AERN-Net-0.2.0/AERN-Net.cabal 0.2.1/AERN-Net-0.2.1/AERN-Net.cabal Single changes: ChangeABC : Entity added to module ModuleName "Control.ERNet.Foundations.Process" --- EThingAll (UnQual (Ident "ERProcessAction")) ---ChangeABC : Module(s) added.(Consider AB change if new modules are likely to cause name collisions) --- "Control/ERNet/Blocks/Real/LFT" --- Biggest change comes from: ChangeABC : Module(s) added.(Consider AB change if new modules are likely to cause name collisions) --- "Control/ERNet/Blocks/Real/LFT" --- 3) Using testing script: package-vt correctly detects that AERN-RnToRM-0.4.9 should rather be 0.5.0 because the module Data.Number.ER.RnToRm.UnitDom.ChebyshevBase.Polynom.Field has been removed. ./test-on-package.lhs AERN-RnToRm --cut-- >>> Testing package-vt on AERN-RnToRm-0.4.2 and AERN-RnToRm-0.4.9 Parse error: VarSym "#" : SrcLoc {srcFilename = "0.4.2/AERN-RnToRm-0.4.2/src/Data/Number/ER/RnToRm/Approx/DomTransl.hs", srcLine = 174, srcColumn = 1} Single changes: ChangeABC : Entity added to module ModuleName "Data.Number.ER.RnToRm.Approx" --- EVar (UnQual (Ident "keyPointsConsistencyCheck")) EVar (UnQual (Ident "keyPointsPointwiseConsistencyCheck")) ---ChangeABC : Entity added to module ModuleName "Data.Number.ER.RnToRm.UnitDom.Approx" --- EVar (UnQual (Ident "keyPointsConsistencyCheck")) EVar (UnQual (Ident "keyPointsPointwiseConsistencyCheck")) ---ChangeAB : Module(s) removed/renamed. --- "Data/Number/ER/RnToRm/UnitDom/ChebyshevBase/Polynom/Field" --- Biggest change comes from: ChangeAB : Module(s) removed/renamed. --- "Data/Number/ER/RnToRm/UnitDom/ChebyshevBase/Polynom/Field" --- ExitSuccess --cut-- In case of any trouble please email me or report an issue here [3]. In the near future I'll post more specific plans about development on my blog [4]. I hope you will find it useful.
