This has the advantage that you can decide how the GHC versions have been installed. The Haskell IDE Engine can also be built with cabal v2-build instead of stack build.
#ATOM HASKELL IDE BACKEND INSTALL#
Install hie for a specific GHC version (and hoogle docs): stack. Install hie for the latest available and supported GHC version (and hoogle docs): stack.
#ATOM HASKELL IDE BACKEND WINDOWS#
Running the script with cabal on windows requires a cabal version greater or equal to 3.0.0.0.įor brevity, only the stack-based commands are presented in the following sections. install.hs -project-file install/shake.project The install-script can be invoked via cabal instead of stack with the command cabal v2-run. However, afterwards all commands should work as expected.

Remember, this will take time to download a Stackage-LTS and an appropriate GHC.
The GHC used for the install.hs can be adjusted in shake.yaml by using a different resolver.Īvailable commands can be seen with: stack. Note, on first invocation of the build script, a GHC is being installed for execution. Uses the shake build system for predictable builds.

#ATOM HASKELL IDE BACKEND UPGRADE#
In addition make sure hie.exe is not running by closing your editor, otherwise in case of an upgrade the executable can not be installed. To set this for all your git repositories use git config -system core.longpaths true (you probably need an administrative shell for this) or for just this one repository use git config core.longpaths true. You also need to configure git to allow longer paths by using unicode paths. If you don't have the policy editor you can use regedit by using the following instructions here. If the Local Group Policy Editor is available on your system, go to: Local Computer Policy -> Computer Configuration -> Administrative Templates -> System -> Filesystem set Enable Win32 long paths to Enabled. If this doesn't work or you want to use a longer path, try the second option. In order to avoid problems with long paths on Windows you can do either one of the following:Ĭlone the haskell-ide-engine to a short path, for example the root of your logical drive (e.g. On Linux you will need install a couple of extra libraries (for Unicode ( ICU) and NCURSES):ĭebian 9/Ubuntu 18.04 or earlier: sudo apt install libicu-dev libtinfo-dev libgmp-devĭebian 10/Ubuntu 18.10 or later: sudo apt install libicu-dev libncurses-dev libgmp-dev # also zlib1g-dev if not installedįedora: sudo dnf install libicu-devel ncurses-devel # also zlib-devel if not already installed Windows-specific pre-requirements Then it means you have the command in PATH. If you receive some meaningful output instead of "command not found"-like message Tip: you can quickly check if some command is in your path by running the command.
