172+## History and relationship to other Haskell IDE's
173+
174+The code behind `ghcide` was originally developed by [Digital Asset](https://digitalasset.com/) as part of the [DAML programming language](https://github.com/digital-asset/daml). DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming langauge has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset.

176+The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that has been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors.

178+The best summary of the architecture of `ghcide` is available [this talk](https://www.youtube.com/watch?v=cijsaeWNf2E&list=PLxxF72uPfQVRdAsvj7THoys-nVj-oc4Ss) ([slides](https://ndmitchell.com/downloads/slides-making_a_haskell_ide-07_sep_2019.pdf)), given at [MuniHac 2019](https://munihac.de/2019.html). However, since that talk the project has renamed from `hie-core` to `ghcide`, and the repo has moved to [this location](https://github.com/digital-asset/ghcide/).
