When we say static binaries, we mean a binary that has no dynamically linked libraries. This has been a long running discussion, that dates all the way back to haskell-ide-engine. One obvious solution would be to just provide static binaries. So many of us have spent the past month hard at work trying to improve the installation story. This isn’t great for newcomers or for those who just want to setup a working IDE in a pinch. On top of this, installation from source is the only supported installation method so far. The wrapper is then used in place of the language server, and will detect what version of GHC the project is using and launch the appropriate version of hie/ haskell-language-server.īuilding all these different binaries with several different versions of GHC means you need to build every single dependency multiple times over, leading to some hefty build times and chewing through a lot of disk space.

The install.hs script will install binaries for every version under haskell-language-server-8.6.5, haskell-language-server-8.8.3, etc. The latter is the purpose of the hie-wrapper/ haskell-language-server-wrapper executable. This means that in order to support multiple GHC versions (which is quite common with Stack projects that can define a specific version of GHC) the install script needs to build a binary of haskell-ide-engine/ haskell-language-server for every single GHC version that is supported. The GHC API that powers the underlying ghcide session only works on projects that match the same GHC version as it was compiled with.These plugins all depend on the corresponding tool from Hackage, and as a result they end up pulling in a lot of transient dependencies.

Both haskell-ide-engine and haskell-language-server act as a kitchen sink for plugins.There are several reasons for this, two of the most significant being: If you’ve ever had to install haskell-ide-engine or haskell-language-server, you might be aware that it is quite a lengthy process.
