plugins's Issues

Loading and Running IO Results in Segfault with newer GHC

I've created a test here which loads an IO () function from a module.

https://github.com/xpika/plugins-ghc-7-10-segfault-io

The code does not segfault on GHC 7.6.3 but does on 7.10.3.

GitHub Actions setup

@stepcut The current Travis setup does not work anymore. In order to improve the reliability of the package's support window, I would like to submit a PR to set up GH Actions. Is that good with you?

GHC 9.2 support is missing

Hi! I'd like to start using plugins for an application of my own.

I tried to depend on it with GHC 9.2 as my compiler, and the following message makes me think that plugins is still trying to look up the old module hierarchy:

src/System/Plugins/LoadTypes.hs:33:1: error:
    Could not find module ‘HscTypes’
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.
   |
33 | import HscTypes
   | ^^^^^^^^^^^^^^^

You're probably busy, so would you accept a PR to fix this?

eval example broken in latest github version

I have been able to successfully compile plugins from github, but the example of the eval function doesn't work anymore.

plugins/src/System/Eval/Haskell.hs

Lines 89 to 90 in 5866046

 -- > do i <- eval "1 + 6 :: Int" [] :: IO (Maybe Int) 

 -- > when (isJust i) $ putStrLn (show (fromJust i))

eval "1 + 6 :: Int" [] :: IO (Maybe Int) just returns Nothing.

build failure against ghc-8.10: src/System/Plugins/Env.hs:81:32: error: Module ‘SysTools’ does not export ‘initLlvmConfig’

Can't build with stack due to missing config.h file

I've been trying to build this package in one of my Haskell projects. I'm using stack and keep getting the errors shown below. I've tried building this on Arch, Linux Mint, and Nixos and with several different versions of stack and ghc. This particular run was with stack 1.9.1, and ghc 8.0.2. I've tried it with stack 1.7.1 and ghc 8.4.4 with the same result. They all produce this same exact error. I've done several searches online and found nothing useful. Any ideas about what's happening and how to fix it?

Can't compile using ghc 9.4

Hi,
I get the following compiling on 9.4.x:

       > [ 4 of 12] Compiling System.Plugins.Parser ( src/System/Plugins/Parser.hs, dist/build/System/Plugins/Parser.o, dist/build/System/Plugins/Parser.dyn_o )
       >
       > src/System/Plugins/Parser.hs:38:1: error:
       >     Ambiguous module name ‘Language.Haskell.Syntax’:
       >       it was found in multiple packages: ghc-9.4.2 haskell-src-1.0.4
       >    |
       > 38 | import Language.Haskell.Syntax

Unsure if one of these packages just reimports another, it may be possible to reduce dependencies now?

Thanks!

Cannot satisfy -package plugins

Tried to run a simple plugins eval example under stack 1.6.3, with plugins-1.5.7 added to extra-deps.

Tried running

module Main where

import System.Eval.Haskell

main :: IO ()
main =
  do
    i <- eval "1+2 :: Int" [] :: IO (Maybe Int)
    print i

and got:

$ scratch-exe
<command line>: cannot satisfy -package plugins
    (use -v for more information)
Nothing

I'm not quite sure where this message is being emitted from, any ideas of what I might have to add?

Thanks!
