Documentation true flag ignored on caba install l 2.0 branch
by Carter Schonwald 28 Jul '17

28 Jul '17

This looks like the last engineering issue for 2.0 release. Is there any way to help out? I've patched my local build to just have the flag set to true by default in the source code ... but I sense we don't want that ;)

mutex-flags
by Lee John 19 Jul '17

19 Jul '17

I think the mutex flags might be needed. For example, if my program use accelerate and I want my program can use both of cuda, llvm, (etc) as the backend for accelerating, I need to write a lot of if-statements in cabal file to control that there will be only one backend to be used. So I think that mutex-flags might be useful. For example: … flag a default: False flag b default: False flag c default: False flag d default: False ... exec… … if flag(a) && !flag(b) && !flag(c) && !flag(d) build-depends: xx-a … if !flag(a) && flag(b) && !flag(c) && !flag(d) build-depends: xx-b … if !flag(a) && !flag(b) && flag(c) && !flag(d) build-depends: xx-c … if !flag(a) && !flag(b) && !flag(c) build-depends: xx-d … The above codes are also hard to maintain or extend. Following codes will better. … flag a default: False flag b default: False flag c default: False flag d default: False mutex flags: a b c d default: d … if flag(a) build-depends: xx-a if flag(b) build-depends: xx-b if flag(c) build-depends: xx-c if flag(d) build-depends: xx-d ...

Summer of Haskell | Cabal Project
by Pranit Bauva 09 May '17

09 May '17

Hey everyone, I am Pranit Bauva and I am interested in participating in the Summer of Haskell program to complete the project "Last Mile for `cabal new-build`". I have got a few PRs merged[1] and I am now working on another one[2]. I have done a GSoC under git last year, so I am quite familiar with the whole process. My motivation to participate in SoH is mainly to learn Haskell and I personally think that contributing to a real world project is the best way to learn a language rather than just doing course exercises. I am currently looking for mentors to help me with the project. Is anybody interested?

Misleading home page link
by Matthew Fernandez 05 May '17

05 May '17

Hello Cabal cabal, The Cabal home page [0] has a link to "Browse open issues or report a new bug.." that points to a filtered search of the Github issues [1]. The label "cabal-install" no longer seems to be used by itself; this search returns no results. Should this just link to all open issues given the home page is about Cabal in the larger sense, not specifically cabal-install? Thanks, Matt [0]: https://www.haskell.org/cabal/ [1]: https://github.com/haskell/cabal/issues?labels=cabal-install&state=open

use data-files without installation
by Henning Thielemann 07 Mar '17

07 Mar '17

In a project I have currently some program text embedded as String in the source code. I like to move that to an extra file, such that I can test the program without running the Haskell code and such that non-Haskell programmers can adapt the text. However, I hesitate to use the Data-Files feature of Cabal since this would mean that I can test the Haskell code only after installation of the whole Cabal package including the text file. Is there a way to use 'cabal repl' with the local version of the text file? This would mean there must be a different variant autogen/Paths_mod.hs, maybe the same file name but in a different directory that is only passed to GHCi by 'cabal repl'. Manageable but certainly surprising? Maybe only available by a new option like 'cabal repl --local-dirs'. More difficult: Can even 'cabal build' incl. dist/build/prog/prog and 'cabal run' use local data files per request? Certainly not, since dist/build/prog/prog shall just be installed by 'cabal install'. Alternatively, is there a way to tell GHC to include a file in the executable and provide access to its content? Would there be support in Cabal for this feature?

Cabal at BayHac 2017
by Kristen Kozak 27 Feb '17

27 Feb '17

Hello, I am considering volunteering at BayHac to help people hack on Cabal, though I don't know enough of the codebase to do it myself. Is anyone else interested in helping? BayHac is April 7th through 9th in San Francisco. Here is the webpage: https://wiki.haskell.org/BayHac2017 . Let me know, and then I'll ask to have Cabal added to the list of projects. Thanks. -Kristen

cabal release binaries for 1.24.0.2 ?
by Gershom B 12 Jan '17

12 Jan '17

I noticed that there there are no binaries for 1.24.0.2 and in fact the webpage still links the source tarball for 1.24.0.1 as the latest? It would be good to get this fixed. —Gershom
