Understanding how warnings on unused functions work
by Razetime 28 Mar '23

28 Mar '23

This message is related to a feature in the futhark compiler <https://github.com/diku-dk/futhark/issues/550>, which is a language with a similar module system. I am trying to create a tool to detect unused top-level functions in Futhark, and I have been looking in the ghc codebase to find out how it does so. So far I have found these areas: 1. warning flag <https://gitlab.haskell.org/ghc/ghc/-/blob/master/compiler/GHC/Driver/Flags.…> 2. WarnUnusedTopBinds <https://gitlab.haskell.org/ghc/ghc/-/blob/master/compiler/GHC/Rename/Utils.…> The project is a bit too big for my machine to take, so HLS is not helping me with finding where the computation of unused bindings (specifically functions) is done. I would like some help with finding where ghc does this computation, and maybe some help with the naming conventions of the code. Thanks in advance.

Buy-in for technical proposal 47 which affect GHC devs
by Laurent P. René de Cotret 26 Mar '23

26 Mar '23

Dear GHC developers, In recent weeks, John Ericson has fine-tuned a Haskell Foundation Technical Proposal to split `base` into two libraries: `ghc-base` and `base`, the latter simply re-exporting everything for `ghc-base` (for now). You can read about the rationale and specifics more in details in the proposal itself: https://github.com/haskellfoundation/tech-proposals/pull/47 Note that this proposal has recently been streamlined into a form which is more focused than its initial state, and might be worth a re-read. The Haskell Foundation Technical Working Group has reached a consensus that this work will benefit the Haskell community. Moreover, the Haskell Foundation has agreed to spend some of its resources to implement this proposal, which would start by ensuring the completion of MR7898 (https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7898) This work will affect GHC developers. Therefore, the Technical Working Group would like to get buy-in from the GHC developers before formally accepting this proposal. Best regards, Laurent P. René de Cotret on behalf of the Haskell Foundation Technical Working Group

Re: Installing GHC on my MacBook Air

Type the following at the command line: xcode-select --install and then try ghci again. I'm not sure what you mean by "the software" in the phrase "Should I delete and reinstall the software you told me to install?" but in any case don't delete anything. Please try to be as specific as possible. When you first encounter a problem you should Google for a solution.

Hi Bill, It's easy to forget to do replay all in gmail but it's important to do so in these emails. In your original email you wrote: After installing the compiler, my laptop said its processor was wrong for the binary distribution I chose. If there is a dmg file for *MacOS 12.5.1,* please please link your reply to it. Can you confirm that you no longer have the problem "of processor was wrong for the binary distribution I chose." ? My understanding is that after that you got the error: libHSterminfo-0.4.1.5-ghc9.4.4.dylib” can’t be opened because Apple cannot check it for malicious software. I then suggested you had encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206 and I suggested you do: rm -fr /usr/local/bin/ghc* rm -fr /usr/local/lib/ghc* ./configure sudo xattr -rc . sudo make install You said you did and got a warning "that some program wanted to access my photos when I don't have any." Can you repeat those steps and cut and paste your terminal session into an email? Unfortunately I am too busy to continue replying but with the above I think somebody will be able to help you.

Hi William I think it's best if you submit a bug as described here <https://gitlab.haskell.org/ghc/ghc/-/wikis/report-a-bug> Whether in email or in the bug report it is critical that you describe how the reader can reproduce the bug, i.e. starting from the beginning, describe what you did and what error message(s) you got.
