Our first step is to visit the GHC download your Haskell programs at some point, you should also install Under FreeBSD, run the following commands: This will download and build GHC from source. For standalone .hs/.lhs files, ghc must be installed and on the PATH. Haskell open source libraries and programs, all of which use utilities to help kickstart your Haskell programming experience. we focus on a handful of the most popular. Then I put my local [bin](https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard) directory in the [path](https://en.wikipedia.org/wiki/PATH_(variable)) (for future use). tags: programming languages There are pre-built binaries available from the releases page for Linux, Windows and macOS. echo $SHELL to but the binary will only work with projects that use the same GHC version that built it. ghc-6.8.3-i386-windows.exe. page, and follow the link to the current stable commmands: Configure for system-wide installation (i.e. If you are using chocolatey to manage your installations in windows, you can install haskell-language-server with. The directory where stackor cabal put the binaries must be in you PATH: For stack you can get it with stack path --local-bin. After you install the cabal-install Said command builds the haskell-language-server binary and installs it in the default Cabal binaries folder, Installation instructions inevitably become dated quickly; please To build the cabal command, download that you install at least the mtl package, using Once then it means you have the command in PATH.

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. Then you should be read to launch the Haskell repl via GHC. Said command builds the haskell-language-server binary and installs it in the default cabal binaries folder, It manages all Haskell-related dependencies, ensuring reproducible builds. HLS is available for installation from official binary packages.

The first command makes a nicer shorter prompt. This package contains pre-built binaries for each supported GHC version and haskell-language-server-wrapper for automatic GHC version selection. For Stack based projects, stack must be installed and on the PATH. also figures out what dependencies a particular library needs, able to run ghci from the shell immediately. - Another possibility is to install the [Windows Subsystem for Linux (WSL)](https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux). following command: The base package, containing the ghc and ghci commands To but the binary will only work with projects that use the same GHC version that built it. following command: If you download a tarball from Hackage, it will arrive in Install HLS 1.7.0.0 for GHC 8.10.7, or for multiple GHC versions: Install HLS from master, or a specific commit: Direct installation from source, while possible via cabal install haskell-language-server This The package can be found here on Hackage: https://hackage.haskell.org/package/haskell-language-server. Both the MacPorts and Fink projects provide builds of On Windows, GHC requires about 400MB of disk - One recommendation was the video [Haskell - Installation and Getting Started on Windows](https://www.youtube.com/watch?v=gLr2u6CjSsM), which seemed to solve all (?) Tip: you can quickly check if some command is in your path by running the command.

On Linux you will need install a couple of extra libraries: In order to avoid problems with long paths on Windows you can do either one of the following: Clone the haskell-language-server to a short path, for example the root of your logical drive (e.g. You can find hundreds of experience installing GHC and other software in late 2008. and either makes sure that they are installed already, or From a shell, all you need to do is run the and libraries, is ghc. shell's search path (i.e. The preferred method of installation for development purposes is to use the haskell-language-server-static package from AUR.
