+GHCup is an installer for the general purpose language [Haskell](https://www.haskell.org/).

-## Installation
-
-Most users should follow the instructions at [https://www.haskell.org/ghcup/](https://www.haskell.org/ghcup/).
-Advanced users may want to perform a [manual installation](#manual-install).
-
-### Supported platforms
-
-This list may not be exhaustive and specifies support for bindists only.

-
-#### Windows 7
-
-May or may not work, several issues:
-
-* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140
-* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197
-
-#### WSL1
-
-Unsupported. GHC may or may not work. Upgrade to WSL2.
-
-#### MacOS <13
-
-Not supported. Would require separate binaries, since >=13 binaries are incompatible.
-Please upgrade.
-
-#### MacOS aarch64
-
-HLS bindists are still experimental. Stack is theoretically supported, but has no binaries yet.
-
-#### FreeBSD
-
-Lacks some upstream bindists and may need compat libs, since most bindists are built on FreeBSD-12.
-HLS bindists are experimental.
-
-#### Linux ARMv7/AARCH64
-
-Lower availability of bindists. HLS only has experimental ones. Stack not supported currently.
-
-### Manual install
-
-Download the binary for your platform at [https://downloads.haskell.org/~ghcup/](https://downloads.haskell.org/~ghcup/)
-and place it into your `PATH` anywhere.
-
-Then adjust your `PATH` in `~/.bashrc` (or similar, depending on your shell) like so:
-
-```sh
-export PATH="$HOME/.cabal/bin:$HOME/.ghcup/bin:$PATH"
-```
-
-### Vim integration
-
-See [ghcup.vim](https://github.com/hasufell/ghcup.vim).
-
-## Usage
-
-See `ghcup --help`.
-
-For the simple interactive TUI, run:
-
-```sh
-ghcup tui
-```
-
-For the full functionality via cli:
-
-```sh
-# list available ghc/cabal versions
-ghcup list
-
-# install the recommended GHC version
-ghcup install ghc
-
-# install a specific GHC version
-ghcup install ghc 8.2.2
-
-# set the currently "active" GHC version
-ghcup set ghc 8.4.4
-
-# install cabal-install
-ghcup install cabal
-
-# update ghcup itself
-ghcup upgrade
-```
-
-GHCup works very well with [`cabal-install`](https://hackage.haskell.org/package/cabal-install), which
-handles your haskell packages and can demand that [a specific version](https://cabal.readthedocs.io/en/latest/nix-local-build.html#cfg-flag---with-compiler)  of `ghc` is available, which `ghcup` can do.
-
-### Configuration
-
-A configuration file can be put in `~/.ghcup/config.yaml`. The default config file
-explaining all possible configurations can be found in this repo: [config.yaml](./data/config.yaml).
-
-Partial configuration is fine. Command line options always override the config file settings.
-
-### GPG verification
-
-GHCup supports verifying the GPG signature of the metadata file. The metadata file then contains SHA256 hashes of all downloads, so
-this is cryptographically secure.
-
-First, obtain the gpg key:
-
-```sh
-gpg --batch --keyserver keys.openpgp.org --recv-keys 7784930957807690A66EBDBE3786C5262ECB4A3F
-```
-
-Then verify the gpg key in one of these ways:
-
-1. find out where I live and visit me to do offline key signing
-2. figure out my mobile phone number and call me to verify the fingerprint
-3. more boring: contact me on Libera IRC (`maerwald`) and verify the fingerprint
-
-Once you've verified the key, you have to figure out if you trust me.
-
-If you trust me, then you can configure gpg in `~/.ghcup/config.yaml`:
-
-```yml
-gpg-setting: GPGLax # GPGStrict | GPGLax | GPGNone
-```
-
-In `GPGStrict` mode, ghcup will fail if verification fails. In `GPGLax` mode it will just print a warning.
-You can also pass the mode via `ghcup --gpg <strict|lax|none>`.
-
-### Manpages
-
-For man pages to work you need [man-db](http://man-db.nongnu.org/) as your `man` provider, then issue `man ghc`. Manpages only work for the currently set ghc.
-`MANPATH` may be required to be unset.
-
-### Shell-completion
-
-Shell completions are in [scripts/shell-completions](./scripts/shell-completions) directory of this repository.
-
-For bash: install `shell-completions/bash`
-as e.g. `/etc/bash_completion.d/ghcup` (depending on distro)
-and make sure your bashrc sources the startup script
-(`/usr/share/bash-completion/bash_completion` on some distros).
-
-### Compiling GHC from source
-
-Compiling from source is supported for both source tarballs and arbitrary git refs. See `ghcup compile ghc --help`
-for a list of all available options.
-
-If you need to overwrite the existing `build.mk`, check the default files
-in [data/build_mk](./data/build_mk), copy them somewhere, adjust them and
-pass `--config path/to/build.mk` to `ghcup compile ghc`.
-Common `build.mk` options are explained [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/using#build-configuration).
-
-Make sure your system meets all the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation).
-
-#### Cross support
-
-ghcup can compile and install a cross GHC for any target. However, this
-requires that the build host has a complete cross toolchain and various
-libraries installed for the target platform.
-
-Consult the GHC documentation on the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/cross-compiling#tools-to-install).
-For distributions with non-standard locations of cross toolchain and
-libraries, this may need some tweaking of `build.mk` or configure args.
-See `ghcup compile ghc --help` for further information.
-
-### XDG support
-
-To enable XDG style directories, set the environment variable `GHCUP_USE_XDG_DIRS` to anything.
-
-Then you can control the locations via XDG environment variables as such:
-
-* `XDG_DATA_HOME`: GHCs will be unpacked in `ghcup/ghc` subdir (default: `~/.local/share`)
-* `XDG_CACHE_HOME`: logs and download files will be stored in `ghcup` subdir (default: `~/.cache`)
-* `XDG_BIN_HOME`: binaries end up here (default: `~/.local/bin`)
-* `XDG_CONFIG_HOME`: the config file is stored in `ghcup` subdir as `config.yaml` (default: `~/.config`)
-
-**Note that `ghcup` makes some assumptions about structure of files in `XDG_BIN_HOME`. So if you have other tools
-installing e.g. stack/cabal/ghc into it, this will likely clash. In that case consider disabling XDG support.**
-
-### Env variables
-
-This is the complete list of env variables that change GHCup behavior:
-
-* `GHCUP_USE_XDG_DIRS`: see [XDG support](#xdg-support) above
-* `TMPDIR`: where ghcup does the work (unpacking, building, ...)
-* `GHCUP_INSTALL_BASE_PREFIX`: the base of ghcup (default: `$HOME`)
-* `GHCUP_CURL_OPTS`: additional options that can be passed to curl
-* `GHCUP_WGET_OPTS`: additional options that can be passed to wget
-* `GHCUP_GPG_OPTS`: additional options that can be passed to gpg
-* `GHCUP_SKIP_UPDATE_CHECK`: Skip the (possibly annoying) update check when you run a command
-* `CC`/`LD` etc.: full environment is passed to the build system when compiling GHC via GHCup
-
-### Installing custom bindists
-
-There are a couple of good use cases to install custom bindists:
-
-1. manually built bindists (e.g. with patches)
-  - example: `ghcup install ghc -u 'file:///home/mearwald/tmp/ghc-eff-patches/ghc-8.10.2-x86_64-deb10-linux.tar.xz' 8.10.2-eff`
-2. GHC head CI bindists
-  - example: `ghcup install ghc -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
-3. DWARF bindists
-  - example: `ghcup install ghc -u 'https://downloads.haskell.org/~ghc/8.10.2/ghc-8.10.2-x86_64-deb10-linux-dwarf.tar.xz' 8.10.2-dwarf`
-
-Since the version parser is pretty lax, `8.10.2-eff` and `head` are both valid versions
-and produce the binaries `ghc-8.10.2-eff` and `ghc-head` respectively.
-GHCup always needs to know which version the bindist corresponds to (this is not automatically
-detected).
-
-### Isolated installs
-
-Ghcup also enables you to install a tool (GHC, Cabal, HLS, Stack) at an isolated location of your choosing.
-These installs, as the name suggests, are separate from your main installs and DO NOT conflict with them.
-
-
- No symlinks are made to these isolated installed tools, you'd have to manually point to them wherever you intend to use them.
-
- These installs, can also NOT be deleted from ghcup, you'd have to go and manually delete these.
-
-You need to use the `--isolate` or `-i` flag followed by the directory path.
-
-Examples:-
-
-1. install an isolated GHC version at location /home/user/isolated_dir/ghc/  
-   - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
-
-2. isolated install Cabal at a location you desire  
-   - `ghcup install cabal --isolate /home/username/my_isolated_dir/`
-
-3. do an isolated install with a custom bindist  
-   - `ghcup install ghc --isolate /home/username/my_isolated_dir/ -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
-
-4. isolated install HLS  
-   - `ghcup install hls --isolate /home/username/dir/hls/`
-
-5. you can even compile ghc to an isolated location.  
-   - `ghcup compile ghc -j 4 -v 9.0.1 -b 8.10.5 -i /home/username/my/dir/ghc` 
-   ---  
-
-### CI
-
-On windows, ghcup can be installed automatically on a CI runner like so:
-
-```ps
-Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\"
-```
-
-On linux/darwin/freebsd, run the following on your runner:
-
-```sh
-curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
-```
-
-This will just install `ghcup` and on windows additionally `msys2`.
-
-#### Example github workflow
-
-On github workflows you can use https://github.com/haskell/actions/
-
-If you want to install ghcup manually though, here's an example config:
-
-```yml
-name: Haskell CI
-
-on:
-  push:
-    branches: [ master ]
-  pull_request:
-    branches: [ master ]
-
-jobs:
-  build-cabal:
-
-    runs-on: ${{ matrix.os }}
-    strategy:
-      fail-fast: false
-      matrix:
-        os: [ubuntu-latest, macOS-latest, windows-latest]
-        ghc: ['8.10.7', '9.0.1']
-        cabal: ['3.4.0.0']
-
-    steps:
-    - uses: actions/checkout@v2
-
-    - if: matrix.os == 'windows-latest'
-      name: Install ghcup on windows
-      run: Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\"
-
-    - if: matrix.os == 'windows-latest'
-      name: Add ghcup to PATH
-      run: echo "/c/ghcup/bin" >> $GITHUB_PATH
-      shell: bash
-
-    - if: matrix.os != 'windows-latest'
-      name: Install ghcup on non-windows
-      run: curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
-
-    - name: Install ghc/cabal
-      run: |
-        ghcup install ghc ${{ matrix.ghc }}
-        ghcup install cabal ${{ matrix.cabal }}
-      shell: bash
-
-    - name: Update cabal index
-      run: cabal update
-      shell: bash
-
-    - name: Build
-      run: cabal build --enable-tests --enable-benchmarks
-      shell: bash
-
-    - name: Run tests
-      run: cabal test
-      shell: bash
-```
-   
-### Tips and tricks
-
-#### with_ghc wrapper (e.g. for HLS)
-
-Due to some HLS [bugs](https://github.com/mpickering/hie-bios/issues/194) it's necessary that the `ghc` in PATH
-is the one defined in `cabal.project`. With some simple shell functions, we can start our editor with the appropriate
-path prepended.
-
-For bash, in e.g. `~/.bashrc` define:
-
-```sh
-with_ghc() {
-  local np=$(ghcup --offline whereis -d ghc $1 || { ghcup --cache install ghc $1 && ghcup whereis -d ghc $1 ;})
-  if [ -e "${np}" ] ; then
-    shift
-    PATH="$np:$PATH" "$@"
-  else
-    >&2 echo "Cannot find or install GHC version $1"
-    return 1
-  fi
-}
-```
-
-For fish shell, in e.g. `~/.config/fish/config.fish` define:
-
-```fish
-function with_ghc
-  set --local np (ghcup --offline whereis -d ghc $argv[1] ; or begin ghcup --cache install ghc $argv[1] ; and ghcup whereis -d ghc $argv[1] ; end)
-  if test -e "$np"
-    PATH="$np:$PATH" $argv[2..-1]
-  else
-    echo "Cannot find or install GHC version $argv[1]" 1>&2
-    return 1
-  end
-end
-```
-
-Then start a new shell and issue:
-
-```sh
-# replace 'code' with your editor
-with_ghc 8.10.5 code path/to/haskell/source
-```
-
-Cabal and HLS will now see `8.10.5` as the primary GHC, without the need to
-run `ghcup set` all the time when switching between projects.
-
-## Design goals
-
-1. simplicity
-2. non-interactive
-3. portable (eh)
-4. do one thing and do it well (UNIX philosophy)
-
-### Non-goals
-
-1. invoking `sudo`, `apt-get` or *any* package manager
-2. handling system packages
-3. handling cabal projects
-4. being a stack alternative
-
-## How
-
-Installs a specified GHC version into `~/.ghcup/ghc/<ver>`, and places `ghc-<ver>` symlinks in `~/.ghcup/bin/`.
-
-Optionally, an unversioned `ghc` link can point to a default version of your choice.
-
-This uses precompiled GHC binaries that have been compiled on fedora/debian by [upstream GHC](https://www.haskell.org/ghc/download_ghc_8_6_1.html#binaries).
-
-Alternatively, you can also tell it to compile from source (note that this might fail due to missing requirements).
-
-In addition this script can also install `cabal-install`.

-
-## Known problems
-
-### Custom ghc version names
-
-When installing ghc bindists with custom version names as outlined in
-[installing custom bindists](#installing-custom-bindists), then cabal might
-be unable to find the correct `ghc-pkg` (also see [#73](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/73))
-if you use `cabal build --with-compiler=ghc-foo`. Instead, point it to the full path, such as:
-`cabal build --with-compiler=$HOME/.ghcup/ghc/<version-name>/bin/ghc` or set that GHC version
-as the current one via: `ghcup set ghc <version-name>`.
-
-This problem doesn't exist for regularly installed GHC versions.
-
-### Limited distributions supported
-
-Currently only GNU/Linux distributions compatible with the [upstream GHC](https://www.haskell.org/ghc/download_ghc_8_6_1.html#binaries) binaries are supported.
-
-### Precompiled binaries
-
-Since this uses precompiled binaries you may run into
-several problems.
-
-#### Missing libtinfo (ncurses)
-
-You may run into problems with *ncurses* and **missing libtinfo**, in case
-your distribution doesn't use the legacy way of building
-ncurses and has no compatibility symlinks in place.
-
-Ask your distributor on how to solve this or
-try to compile from source via `ghcup compile <version>`.
-
-#### Libnuma required
-
-This was a [bug](https://ghc.haskell.org/trac/ghc/ticket/15688) in the build system of some GHC versions that lead to
-unconditionally enabled libnuma support. To mitigate this you might have to install the libnuma
-package of your distribution. See [here](https://gitlab.haskell.org/haskell/ghcup/issues/58) for a discussion.
-
-### Compilation
-
-Although this script can compile GHC for you, it's just a very thin
-wrapper around the build system. It makes no effort in trying
-to figure out whether you have the correct toolchain and
-the correct dependencies. Refer to [the official docs](https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Linux)
-on how to prepare your environment for building GHC.
-
-### Stack support
-
-There may be a number of bugs when trying to make ghcup installed GHC versions work with stack,
-such as:
-
- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/188
-
-Further, stack's upgrade procedure may break/confuse ghcup. There are a number of integration
-issues discussed here:
-
- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/153
-
-### Windows support
-
-Windows support is in early stages. Since windows doesn't support symbolic links properly,
-ghcup uses a [shimgen wrapper](https://github.com/71/scoop-better-shimexe). It seems to work
-well, but there may be unknown issues with that approach.
-
-Windows 7 and Powershell 2.0 aren't well supported at the moment, also see:
-
- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140
- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197
-
-## FAQ
-
-### Why reimplement stack?
-
-GHCup is not a reimplementation of stack. The only common part is automatic installation of GHC,
-but even that differs in scope and design.
-
-### Why should I use ghcup over stack?
-
-GHCup is not a replacement for stack. Instead, it supports installing and managing stack versions.
-It does the same for cabal, GHC and HLS. As such, It doesn't make a workflow choice for you.
-
-### Why should I let ghcup manage stack?
-
-You don't need to. However, some users seem to prefer to have a central tool that manages cabal and stack
-at the same time. Additionally, it can allow better sharing of GHC installation across these tools.
-Also see:
-
-* https://docs.haskellstack.org/en/stable/yaml_configuration/#system-ghc
-* https://github.com/commercialhaskell/stack/pull/5585
-
-### Why does ghcup not use stack code?
-
-Oddly, this question has been asked a couple of times. For the curious, here are a few reasons:
-
-1. GHCup started as a shell script. At the time of rewriting it in Haskell, the authors didn't even know that stack exposes *some* of its [installation API](https://hackage.haskell.org/package/stack-2.5.1.1/docs/Stack-Setup.html)
-2. Even if they did, it doesn't seem it would have satisfied their needs
-	  - it didn't support cabal installation, which was the main motivation behind GHCup back then
-	  - depending on a codebase as big as stack for a central part of one's application without having a short contribution pipeline would likely have caused stagnation or resulted in simply copy-pasting the relevant code in order to adjust it
-	  - it's not clear how GHCup would have been implemented with the provided API. It seems the codebases are fairly different. GHCup does a lot of symlink handling to expose a central `bin/` directory that users can easily put in PATH, without having to worry about anything more. It also provides explicit removal functionality, GHC cross-compilation, a TUI, etc etc.
-3. GHCup is built around unix principles and supposed to be simple.
-
-### Why not unify...
-
-#### ...stack and Cabal and do away with standalone installers
-
-GHCup is not involved in such decisions. cabal-install and stack might have a
-sufficiently different user experience to warrant having a choice.
-
-#### ...installer implementations and have a common library
-
-This sounds like an interesting goal. However, GHC installation isn't a hard engineering problem
-and the shared code wouldn't be too exciting. For such an effort to make sense, all involved
-parties would need to collaborate and have a short pipeline to get patches in.
-
-It's true this would solve the integration problem, but following unix principles, we can
-do similar via **hooks**. Both cabal and stack can support installation hooks. These hooks
-can then call into ghcup or anything else, also see:
-
-* https://github.com/haskell/cabal/issues/7394
-* https://github.com/commercialhaskell/stack/pull/5585
-
-#### ...installers (like, all of it)
-
-So far, there hasn't been an **open** discussion about this. Is this even a good idea?
-Sometimes projects converge eventually if their overlap is big enough, sometimes they don't.
-
-While unification sounds like a simplification of the ecosystem, it also takes away choice.
-Take `curl` and `wget` as an example.
-
-How bad do we need this?
-
-### Why not support windows?
-
-Windows is supported since GHCup version 0.1.15.1.
-
-### Why the haskell reimplementation?
-
-GHCup started as a portable posix shell script of maybe 50 LOC. GHC installation itself can be carried out in
-about ~3 lines of shell code (download, unpack , configure+make install). However, much convenient functionality
-has been added since, as well as ensuring that all operations are safe and correct. The shell script ended up with
-over 2k LOC, which was very hard to maintain.
-
-The main concern when switching from a portable shell script to haskell was platform/architecture support.
-However, ghcup now re-uses GHCs CI infrastructure and as such is perfectly in sync with all platforms that
-GHC supports.
-
-### Is GHCup affiliated with the Haskell Foundation?
-
-There has been some collaboration: Windows and Stack support were mainly requested by the Haskell Foundation
-and those seemed interesting features to add.
-
-Other than that, GHCup is dedicated only to its users and is supported by haskell.org through hosting and CI
-infrastructure.

-# HACKING
-
-## Design decisions
-
-### Using [Excepts](https://hackage.haskell.org/package/haskus-utils-variant-3.0/docs/Haskus-Utils-Variant-Excepts.html) as a beefed up ExceptT
-
-This is an open variant, similar to [plucky](https://hackage.haskell.org/package/plucky) or [oops](https://github.com/i-am-tom/oops) and allows us to combine different error types. Maybe it is too much and it's a little bit [unergonomic](https://github.com/haskus/packages/issues/32) at times. If it really hurts maintenance, it will be removed. It was more of an experiment.
-
-### No use of haskell-TLS
-
-I consider haskell-TLS an interesting experiment, but not a battle-tested and peer-reviewed crypto implementation. There is little to no research about what the intricacies of using haskell for low-level crypto are and how vulnerable such binaries are. Instead, we use either curl the binary (for FreeBSD and mac) or http-io-streams, which works with OpenSSL bindings.
-
-### Optics instead of lens
-
-They're a little safer (less Monoid weirdness with view) and have better error messages. Consider the following wit lens
-
-```
-> view (_Just . to (++ "abc")) Nothing
-""
-```
-
-vs optics
-
-```
-> view (_Just % to (++ "abc")) Nothing
-
-<interactive>:2:1: error:
-    • An_AffineFold cannot be used as A_Getter
-    • In the expression: view (_Just % to (++ "abc")) Nothing
-      In an equation for ‘it’: it = view (_Just % to (++ "abc")) Nothing
-```
-
-### Strict and StrictData on by default
-
-Kazu Yamamoto [explained it in his PR](https://github.com/yesodweb/wai/pull/752#issuecomment-501531386) very well. I like to agree with him. The instances where we need non-strict behavior, we annotate it.
-
-## Code style and formatting
-
-1. Brittany
-2. mtl-style preferred
-3. no overly pointfree style
-
-## Code structure
-
-Main functionality is in `GHCup` module. Utility functions are
-organised tree-ish in `GHCup.Utils` and `GHCup.Utils.*`.
-
-Anything dealing with ghcup specific directories is in
-`GHCup.Utils.Dirs`.
-
-Download information on where to fetch bindists from is in the appropriate
-yaml files: `ghcup-<yaml-ver>.yaml`.
-
-## Common Tasks
-
-### Adding a new GHC version
-
-1. open the latest `ghcup-<yaml-ver>.yaml`
-2. find the latest ghc version (in yaml tree e.g. `ghcupDownloads -> GHC -> 8.10.3`)
-3. copy-paste it
-4. adjust the version, tags, changelog, source url
-5. adjust the various bindist urls (make sure to also change the yaml anchors)
-6. run `cabal run exe:ghcup-gen -- check-tarballs -f ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.4'`
-
-## Major refactors
-
-1. First major refactor included adding cross support. This added
-   `GHCTargetVersion`, which includes the target in addition to the version.
-   Most of the `Version` parameters to functions had to be replaced with
-   that and ensured the logic is consistent for cross and non-cross
-   installs.
-2. This refactor added windows support wrt [#130](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/130).
-   The major changes here were switching `hpath` library out for `filepath`/`directory` (sadly) and
-   introducing a non-unix way of handling processes via the `process` library. It also introduced considerable
-   amounts of CPP wrt file handling, installation etc.

-# RELEASING
-
-1. Update version in `ghcup.cabal` and `boostrap-haskell` (`ghver` variable at the top of the script)
-
-2. Update `GHCup.Version` module. `ghcupURL` must only be updated if we change the `GHCupInfo` type or the YAML representation of it. The version of the YAML represents the change increments. `ghcUpVer` is the current application version, read from `ghcup.cabal`.
-
-3. Add ChangeLog entry
-
-4. Add/fix downloads in `ghcup-<ver>.yaml` (under `data/metadata`), then verify with `ghcup-gen check -f ghcup-<ver>.yaml` and possibly (example only) `ghcup-gen check-tarballs -f ghcup-<ver>.yaml -u 'ghc-8.10.7'`. Generally, new GHC/cabal/stack/hls versions are only added to the latest yaml file. New GHCup versions are added to all (great care must be taken here to not break the parser... e.g. ARM platforms don't parse in all older formats).
-
-5. Commit and git push with tag. Wait for tests to succeed and release artifacts to build.
-
-6. Download release artifacts and upload them `downloads.haskell.org/ghcup` along with checksum files (`sha256sum --tag * > SHA256SUMS && gpg --detach-sign -u <your-email> SHA256SUMS`)
-
-7. Add ghcup release artifacts to ALL yaml files (see point 4.)
-
-8. Upload the final `ghcup-<ver>.yaml` to `webhost.haskell.org/ghcup/data/`.
-
-9. Update `bootstrap-haskell` and `bootstrap-haskell.ps1` to `webhost.haskell.org/ghcup/sh/`
-
-10. Update the ghcup symlinks at `downloads.haskell.org/ghcup`

+## Design goals
+
+1. simplicity
+2. non-interactive CLI interface
+3. portable
+4. do one thing and do it well (UNIX philosophy)
+
+## Non-goals
+
+1. invoking `sudo`, `apt-get` or *any* package manager
+2. handling system packages
+3. handling cabal projects
+4. being a stack alternative
+
+## How
+
+Installs a specified GHC version into `~/.ghcup/ghc/<ver>`, and places `ghc-<ver>` symlinks in `~/.ghcup/bin/`.
+
+Optionally, an unversioned `ghc` link can point to a default version of your choice.
+
+This uses precompiled GHC binaries that have been compiled on fedora/debian by [upstream GHC](https://www.haskell.org/ghc/download_ghc_8_6_1.html#binaries).
+
+Alternatively, you can also tell it to compile from source (note that this might fail due to missing requirements).
+
+cabal-install/HLS/stack are installed in `~/.ghcup/bin/<tool>-<ver>` and have unversioned symlinks to the latest version by default (`~/.ghcup/bin/<tool>-<ver>`).
+

+
+## Known problems
+
+### Custom ghc version names
+
+When installing ghc bindists with custom version names as outlined in
+[installing custom bindists](#installing-custom-bindists), then cabal might
+be unable to find the correct `ghc-pkg` (also see [#73](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/73))
+if you use `cabal build --with-compiler=ghc-foo`. Instead, point it to the full path, such as:
+`cabal build --with-compiler=$HOME/.ghcup/ghc/<version-name>/bin/ghc` or set that GHC version
+as the current one via: `ghcup set ghc <version-name>`.
+
+This problem doesn't exist for regularly installed GHC versions.
+
+### Limited distributions supported
+
+Currently only GNU/Linux distributions compatible with the [upstream GHC](https://www.haskell.org/ghc/download_ghc_8_6_1.html#binaries) binaries are supported.
+
+### Precompiled binaries
+
+Since this uses precompiled binaries you may run into
+several problems.
+
+#### Missing libtinfo (ncurses)
+
+You may run into problems with *ncurses* and **missing libtinfo**, in case
+your distribution doesn't use the legacy way of building
+ncurses and has no compatibility symlinks in place.
+
+Ask your distributor on how to solve this or
+try to compile from source via `ghcup compile <version>`.
+
+#### Libnuma required
+
+This was a [bug](https://ghc.haskell.org/trac/ghc/ticket/15688) in the build system of some GHC versions that lead to
+unconditionally enabled libnuma support. To mitigate this you might have to install the libnuma
+package of your distribution. See [here](https://gitlab.haskell.org/haskell/ghcup/issues/58) for a discussion.
+
+### Compilation
+
+Although this script can compile GHC for you, it's just a very thin

+### Stack support
+
+There may be a number of bugs when trying to make ghcup installed GHC versions work with stack,
+such as:
+
+- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/188
+
+Further, stack's upgrade procedure may break/confuse ghcup. There are a number of integration
+issues discussed here:
+
+- https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/153
+
+### Windows support
+
+Windows support is in early stages. Since windows doesn't support symbolic links properly,
+ghcup uses a [shimgen wrapper](https://github.com/71/scoop-better-shimexe). It seems to work
+well, but there may be unknown issues with that approach.
+
+Windows 7 and Powershell 2.0 aren't well supported at the moment, also see:

+
+## FAQ
+
+### Why reimplement stack?
+
+GHCup is not a reimplementation of stack. The only common part is automatic installation of GHC,
+but even that differs in scope and design.
+
+### Why should I use ghcup over stack?
+
+GHCup is not a replacement for stack. Instead, it supports installing and managing stack versions.
+It does the same for cabal, GHC and HLS. As such, It doesn't make a workflow choice for you.
+
+### Why should I let ghcup manage stack?
+
+You don't need to. However, some users seem to prefer to have a central tool that manages cabal and stack
+at the same time. Additionally, it can allow better sharing of GHC installation across these tools.
+Also see:
+
+* https://docs.haskellstack.org/en/stable/yaml_configuration/#system-ghc
+* https://github.com/commercialhaskell/stack/pull/5585
+
+### Why does ghcup not use stack code?
+
+1. GHCup started as a shell script. At the time of rewriting it in Haskell, the authors didn't even know that stack exposes *some* of its [installation API](https://hackage.haskell.org/package/stack-2.5.1.1/docs/Stack-Setup.html)
+2. it doesn't support cabal installation, which was the main motivation behind GHCup back then
+3. depending on a codebase as big as stack for a central part of one's application without having a short contribution pipeline would likely have caused stagnation or resulted in simply copy-pasting the relevant code in order to adjust it
+4. it's not clear how GHCup would have been implemented with the provided API. It seems the codebases are fairly different. GHCup does a lot of symlink handling to expose a central `bin/` directory that users can easily put in PATH, without having to worry about anything more. It also provides explicit removal functionality, GHC cross-compilation, a TUI, etc etc.
+
+### Why not unify...
+
+#### ...stack and Cabal and do away with standalone installers
+
+GHCup is not involved in such decisions. cabal-install and stack might have a
+sufficiently different user experience to warrant having a choice.
+
+#### ...installer implementations and have a common library
+
+This sounds like an interesting goal. However, GHC installation isn't a hard engineering problem
+and the shared code wouldn't be too exciting. For such an effort to make sense, all involved
+parties would need to collaborate and have a short pipeline to get patches in.
+
+It's true this would solve the integration problem, but following unix principles, we can
+do similar via **hooks**. Both cabal and stack can support installation hooks. These hooks
+can then call into ghcup or anything else, also see:
+
+* https://github.com/haskell/cabal/issues/7394
+* https://github.com/commercialhaskell/stack/pull/5585
+
+#### ...installers (like, all of it)
+
+So far, there hasn't been an open discussion about this. Is this even a good idea?
+Sometimes projects converge eventually if their overlap is big enough, sometimes they don't.
+
+While unification sounds like a simplification of the ecosystem, it also takes away choice.
+Take `curl` and `wget` as an example.
+
+### Why not support windows?
+
+Windows is supported since GHCup version 0.1.15.1.
+
+### Why the haskell reimplementation?
+
+GHCup started as a portable posix shell script of maybe 50 LOC. GHC installation itself can be carried out in
+about ~3 lines of shell code (download, unpack , configure+make install). However, much convenient functionality
+has been added since, as well as ensuring that all operations are safe and correct. The shell script ended up with
+over 2k LOC, which was very hard to maintain.
+
+The main concern when switching from a portable shell script to haskell was platform/architecture support.
+However, ghcup now re-uses GHCs CI infrastructure and as such is perfectly in sync with all platforms that
+GHC supports.

+# Development
+
+All you wanted to know about GHCup development.
+
+## Module graph
+
+[![Module graph](./modules_small.svg){: .center style="width:900px"}](./modules_wide.svg)
+
+Main functionality is in `GHCup` module. Utility functions are
+organised tree-ish in `GHCup.Utils` and `GHCup.Utils.*`.
+
+Anything dealing with ghcup specific directories is in
+`GHCup.Utils.Dirs`.
+
+Download information on where to fetch bindists from is in the appropriate
+yaml files: `data/metadata/ghcup-<yaml-ver>.yaml`.
+
+## Design decisions
+
+### Using [Excepts](https://hackage.haskell.org/package/haskus-utils-variant-3.0/docs/Haskus-Utils-Variant-Excepts.html) as a beefed up ExceptT
+
+This is an open variant, similar to [plucky](https://hackage.haskell.org/package/plucky) or [oops](https://github.com/i-am-tom/oops) and allows us to combine different error types. Maybe it is too much and it's a little bit [unergonomic](https://github.com/haskus/packages/issues/32) at times. If it really hurts maintenance, it will be removed. It was more of an experiment.
+
+### No use of haskell-TLS
+
+I consider haskell-TLS an interesting experiment, but not a battle-tested and peer-reviewed crypto implementation. There is little to no research about what the intricacies of using haskell for low-level crypto are and how vulnerable such binaries are. Instead, we use either curl the binary or wget. There's also an implementation based on OpenSSL bindings, but it isn't enabled by default, since it would complicate shipping static binaries.
+
+### Optics instead of lens
+
+They're a little safer (less Monoid weirdness with view) and have better error messages. Consider the following with [lens](https://hackage.haskell.org/package/lens):
+
+```
+> view (_Just . to (++ "abc")) Nothing
+""
+```
+
+vs [optics](https://hackage.haskell.org/package/optics):
+
+```
+> view (_Just % to (++ "abc")) Nothing
+
+<interactive>:2:1: error:
+    • An_AffineFold cannot be used as A_Getter
+    • In the expression: view (_Just % to (++ "abc")) Nothing
+      In an equation for ‘it’: it = view (_Just % to (++ "abc")) Nothing
+```
+
+### StrictData on by default
+
+Kazu Yamamoto [explained it in his PR](https://github.com/yesodweb/wai/pull/752#issuecomment-501531386) very well. I like to agree with him. The instances where we need non-strict behavior, we annotate it.
+
+`Strict` is a little more odd as a default, since it depends on how you define your functions as well.
+
+## Code style and formatting
+
+Unfortunately, code formatters are semi-broken on this codebase, due to TH and CPP.
+
+Some light suggestions:
+
+1. mtl-style preferred
+2. no overly pointfree style
+3. use `where` a lot, so the main function body reads like prose
+4. documentation is part of the code
+
+## Common Tasks
+
+### Adding a new GHC version
+
+1. open the latest `data/metadata/ghcup-<yaml-ver>.yaml`
+2. find the latest ghc version (in yaml tree e.g. `ghcupDownloads -> GHC -> 8.10.7`)
+3. copy-paste it
+4. adjust the version, tags, changelog, source url
+5. adjust the various bindist urls (make sure to also change the yaml anchors)
+6. run `cabal run exe:ghcup-gen -- check          -f data/metadata/ghcup-<yaml-ver>.yaml`
+7. run `cabal run exe:ghcup-gen -- check-tarballs -f data/metadata/ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.8'`
+
+### Adding a new CLI command
+
+An example illustration on how to deal with [optparse-applicative](https://hackage.haskell.org/package/optparse-applicative) can be seen here: [https://gitlab.haskell.org/haskell/ghcup-hs/-/commit/c19dd5ee8b2edbaf0336af143f1c75b6f4843e26](https://gitlab.haskell.org/haskell/ghcup-hs/-/commit/c19dd5ee8b2edbaf0336af143f1c75b6f4843e26)
+
+## Major refactors
+
+1. First major refactor included adding cross support. This added
+   `GHCTargetVersion`, which includes the target in addition to the version.
+   Most of the `Version` parameters to functions had to be replaced with
+   that and ensured the logic is consistent for cross and non-cross
+   installs.
+2. This refactor added windows support wrt [#130](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/130).
+   The major changes here were switching `hpath` library out for `filepath`/`directory` (sadly) and
+   introducing a non-unix way of handling processes via the `process` library. It also introduced considerable
+   amounts of CPP wrt file handling, installation etc.
+
+# Releasing
+
+1. Update version in `ghcup.cabal` and `boostrap-haskell` (`ghver` variable at the top of the script)
+
+2. Update `GHCup.Version` module. `ghcupURL` must only be updated if we change the `GHCupInfo` type or the YAML representation of it. The version of the YAML represents the change increments. `ghcUpVer` is the current application version, read from `ghcup.cabal`.
+
+3. Add ChangeLog entry
+
+4. Add/fix downloads in `ghcup-<ver>.yaml` (under `data/metadata`), then verify with `ghcup-gen check -f data/metadata/ghcup-<ver>.yaml` and possibly (example only) `ghcup-gen check-tarballs -f data/metadata/ghcup-<ver>.yaml -u 'ghc-8.10.7'`. Generally, new GHC/cabal/stack/hls versions are only added to the latest yaml file. New GHCup versions are added to all (great care must be taken here to not break the parser... e.g. ARM platforms don't parse in all older formats).
+
+5. Commit and git push with tag. Wait for tests to succeed and release artifacts to build.
+
+6. Download release artifacts and upload them `downloads.haskell.org/~ghcup` along with checksum files (`sha256sum --tag * > SHA256SUMS && gpg --detach-sign -u <your-email> SHA256SUMS`)
+
+7. Add ghcup release artifacts to ALL yaml files (see point 4.)
+
+8. Upload the final `data/metadata/ghcup-<ver>.yaml` (and a detached GPG sig of it) to `webhost.haskell.org/ghcup/data/`.
+
+9. Update `bootstrap-haskell` and `bootstrap-haskell.ps1` to `webhost.haskell.org/ghcup/sh/`
+
+10. Update the top-level ghcup symlinks at `downloads.haskell.org/~ghcup`
+
+11. Post on reddit/discourse/etc. and collect rewards

+`ghcup --help` is your friend.
+
+## Basic usage
+
+For the simple interactive TUI (not available on windows), run:
+
+```sh
+ghcup tui
+```
+
+For the full functionality via cli:
+
+```sh
+# list available ghc/cabal versions
+ghcup list
+
+# install the recommended GHC version
+ghcup install ghc
+
+# install a specific GHC version
+ghcup install ghc 8.2.2
+
+# set the currently "active" GHC version
+ghcup set ghc 8.4.4
+
+# install cabal-install
+ghcup install cabal
+
+# update ghcup itself
+ghcup upgrade
+```
+
+## Configuration
+
+A configuration file can be put in `~/.ghcup/config.yaml`. The default config file
+explaining all possible configurations can be found in this repo: [config.yaml](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/data/config.yaml).
+
+Partial configuration is fine. Command line options always override the config file settings.
+
+## GPG verification
+
+GHCup supports verifying the GPG signature of the metadata file. The metadata file then contains SHA256 hashes of all downloads, so
+this is cryptographically secure.
+
+First, obtain the gpg key:
+
+```sh
+gpg --batch --keyserver keys.openpgp.org --recv-keys 7784930957807690A66EBDBE3786C5262ECB4A3F
+```
+
+Then verify the gpg key in one of these ways:
+
+1. find out where I live and visit me to do offline key signing
+2. figure out my mobile phone number and call me to verify the fingerprint
+3. more boring: contact me on Libera IRC (`maerwald`) and verify the fingerprint
+
+Once you've verified the key, you have to figure out if you trust me.
+
+If you trust me, then you can configure gpg in `~/.ghcup/config.yaml`:
+
+```yml
+gpg-setting: GPGLax # GPGStrict | GPGLax | GPGNone
+```
+
+In `GPGStrict` mode, ghcup will fail if verification fails. In `GPGLax` mode it will just print a warning.
+You can also pass the mode via `ghcup --gpg <strict|lax|none>`.
+
+## Manpages
+
+For man pages to work you need [man-db](http://man-db.nongnu.org/) as your `man` provider, then issue `man ghc`. Manpages only work for the currently set ghc.
+`MANPATH` may be required to be unset.
+
+## Shell-completion
+
+Shell completions are in [scripts/shell-completions](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/scripts/shell-completions) directory of this repository.
+
+For bash: install `shell-completions/bash`
+as e.g. `/etc/bash_completion.d/ghcup` (depending on distro)
+and make sure your bashrc sources the startup script
+(`/usr/share/bash-completion/bash_completion` on some distros).
+
+## Compiling GHC from source
+
+Compiling from source is supported for both source tarballs and arbitrary git refs. See `ghcup compile ghc --help`
+for a list of all available options.
+
+If you need to overwrite the existing `build.mk`, check the default files
+in [data/build_mk](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/data/build_mk), copy them somewhere, adjust them and
+pass `--config path/to/build.mk` to `ghcup compile ghc`.
+Common `build.mk` options are explained [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/using#build-configuration).
+
+Make sure your system meets all the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation).
+
+### Cross support
+
+ghcup can compile and install a cross GHC for any target. However, this
+requires that the build host has a complete cross toolchain and various
+libraries installed for the target platform.
+
+Consult the GHC documentation on the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/cross-compiling#tools-to-install).
+For distributions with non-standard locations of cross toolchain and
+libraries, this may need some tweaking of `build.mk` or configure args.
+See `ghcup compile ghc --help` for further information.
+
+## XDG support
+
+To enable XDG style directories, set the environment variable `GHCUP_USE_XDG_DIRS` to anything.
+
+Then you can control the locations via XDG environment variables as such:
+
+* `XDG_DATA_HOME`: GHCs will be unpacked in `ghcup/ghc` subdir (default: `~/.local/share`)
+* `XDG_CACHE_HOME`: logs and download files will be stored in `ghcup` subdir (default: `~/.cache`)
+* `XDG_BIN_HOME`: binaries end up here (default: `~/.local/bin`)
+* `XDG_CONFIG_HOME`: the config file is stored in `ghcup` subdir as `config.yaml` (default: `~/.config`)
+
+**Note that `ghcup` makes some assumptions about structure of files in `XDG_BIN_HOME`. So if you have other tools
+installing e.g. stack/cabal/ghc into it, this will likely clash. In that case consider disabling XDG support.**
+
+## Env variables
+
+This is the complete list of env variables that change GHCup behavior:
+
+* `GHCUP_USE_XDG_DIRS`: see [XDG support](#xdg-support) above
+* `TMPDIR`: where ghcup does the work (unpacking, building, ...)
+* `GHCUP_INSTALL_BASE_PREFIX`: the base of ghcup (default: `$HOME`)
+* `GHCUP_CURL_OPTS`: additional options that can be passed to curl
+* `GHCUP_WGET_OPTS`: additional options that can be passed to wget
+* `GHCUP_GPG_OPTS`: additional options that can be passed to gpg
+* `GHCUP_SKIP_UPDATE_CHECK`: Skip the (possibly annoying) update check when you run a command
+* `CC`/`LD` etc.: full environment is passed to the build system when compiling GHC via GHCup
+
+## Installing custom bindists
+
+There are a couple of good use cases to install custom bindists:
+
+1. manually built bindists (e.g. with patches)
+    - example: `ghcup install ghc -u 'file:///home/mearwald/tmp/ghc-eff-patches/ghc-8.10.2-x86_64-deb10-linux.tar.xz' 8.10.2-eff`
+2. GHC head CI bindists
+    - example: `ghcup install ghc -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
+3. DWARF bindists
+    - example: `ghcup install ghc -u 'https://downloads.haskell.org/~ghc/8.10.2/ghc-8.10.2-x86_64-deb10-linux-dwarf.tar.xz' 8.10.2-dwarf`
+
+Since the version parser is pretty lax, `8.10.2-eff` and `head` are both valid versions
+and produce the binaries `ghc-8.10.2-eff` and `ghc-head` respectively.
+GHCup always needs to know which version the bindist corresponds to (this is not automatically
+detected).
+
+## Isolated installs
+
+Ghcup also enables you to install a tool (GHC, Cabal, HLS, Stack) at an isolated location of your choosing.
+These installs, as the name suggests, are separate from your main installs and DO NOT conflict with them.
+
+
+- No symlinks are made to these isolated installed tools, you'd have to manually point to them wherever you intend to use them.
+
+- These installs, can also NOT be deleted from ghcup, you'd have to go and manually delete these.
+
+You need to use the `--isolate` or `-i` flag followed by the directory path.
+
+Examples:
+
+1. install an isolated GHC version at location /home/user/isolated_dir/ghc/  
+    - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
+
+2. isolated install Cabal at a location you desire  
+    - `ghcup install cabal --isolate /home/username/my_isolated_dir/`
+
+3. do an isolated install with a custom bindist  
+    - `ghcup install ghc --isolate /home/username/my_isolated_dir/ -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
+
+4. isolated install HLS  
+    - `ghcup install hls --isolate /home/username/dir/hls/`
+
+5. you can even compile ghc to an isolated location.  
+    - `ghcup compile ghc -j 4 -v 9.0.1 -b 8.10.5 -i /home/username/my/dir/ghc` 
+
+## Continuous integration
+
+On windows, ghcup can be installed automatically on a CI runner non-interactively like so:
+
+```ps
+Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\"
+```
+
+On linux/darwin/freebsd, run the following on your runner:
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
+```
+
+This will just install `ghcup` and on windows additionally `msys2`.
+
+For the full list of env variables and parameters to tweak the script behavior, see:
+
+* [bootstrap-haskell for linux/darwin/freebsd](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/scripts/bootstrap/bootstrap-haskell#L7)
+* [bootstrap-haskell.ps1 for windows](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/scripts/bootstrap/bootstrap-haskell.ps1#L17)
+
+### Example github workflow
+
+On github workflows you can use [https://github.com/haskell/actions/](https://github.com/haskell/actions/)
+
+If you want to install ghcup manually though, here's an example config:
+
+```yml
+name: Haskell CI
+
+on:
+  push:
+    branches: [ master ]
+  pull_request:
+    branches: [ master ]
+
+jobs:
+  build-cabal:
+
+    runs-on: ${{ matrix.os }}
+    strategy:
+      fail-fast: false
+      matrix:
+        os: [ubuntu-latest, macOS-latest, windows-latest]
+        ghc: ['8.10.7', '9.0.1']
+        cabal: ['3.4.0.0']
+
+    steps:
+    - uses: actions/checkout@v2
+
+    - if: matrix.os == 'windows-latest'
+      name: Install ghcup on windows
+      run: Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\"
+
+    - if: matrix.os == 'windows-latest'
+      name: Add ghcup to PATH
+      run: echo "/c/ghcup/bin" >> $GITHUB_PATH
+      shell: bash
+
+    - if: matrix.os != 'windows-latest'
+      name: Install ghcup on non-windows
+      run: curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
+
+    - name: Install ghc/cabal
+      run: |
+        ghcup install ghc ${{ matrix.ghc }}
+        ghcup install cabal ${{ matrix.cabal }}
+      shell: bash
+
+    - name: Update cabal index
+      run: cabal update
+      shell: bash
+
+    - name: Build
+      run: cabal build --enable-tests --enable-benchmarks
+      shell: bash
+
+    - name: Run tests
+      run: cabal test
+      shell: bash
+```
+   
+## Tips and tricks
+
+### with_ghc wrapper (e.g. for HLS)
+
+Due to some HLS [bugs](https://github.com/mpickering/hie-bios/issues/194) it's necessary that the `ghc` in PATH
+is the one defined in `cabal.project`. With some simple shell functions, we can start our editor with the appropriate
+path prepended.
+
+For bash, in e.g. `~/.bashrc` define:
+
+```sh
+with_ghc() {
+  local np=$(ghcup --offline whereis -d ghc $1 || { ghcup --cache install ghc $1 && ghcup whereis -d ghc $1 ;})
+  if [ -e "${np}" ] ; then
+    shift
+    PATH="$np:$PATH" "$@"
+  else
+    >&2 echo "Cannot find or install GHC version $1"
+    return 1
+  fi
+}
+```
+
+For fish shell, in e.g. `~/.config/fish/config.fish` define:
+
+```fish
+function with_ghc
+  set --local np (ghcup --offline whereis -d ghc $argv[1] ; or begin ghcup --cache install ghc $argv[1] ; and ghcup whereis -d ghc $argv[1] ; end)
+  if test -e "$np"
+    PATH="$np:$PATH" $argv[2..-1]
+  else
+    echo "Cannot find or install GHC version $argv[1]" 1>&2
+    return 1
+  end
+end
+```
+
+Then start a new shell and issue:
+
+```sh
+# replace 'code' with your editor
+with_ghc 8.10.5 code path/to/haskell/source
+```
+
+Cabal and HLS will now see `8.10.5` as the primary GHC, without the need to
+run `ghcup set` all the time when switching between projects.

+# Getting started
+
+GHCup makes it easy to install specific versions of GHC on GNU/Linux,
+macOS (aka Darwin), FreeBSD and Windows and can also bootstrap a fresh [Haskell developer environment](./install/#supported-tools) from scratch.
+It follows the unix UNIX philosophy of [do one thing and do it well](https://en.wikipedia.org/wiki/Unix_philosophy#Do_One_Thing_and_Do_It_Well). Similar in scope to [rustup](https://github.com/rust-lang-nursery/rustup.rs), [pyenv](https://github.com/pyenv/pyenv) and [jenv](http://www.jenv.be).
+
+## Installation
+
+The following commands will download the `ghcup` binary into `~/.ghcup/bin` (or `C:\ghcup\bin` on windows) and then
+run it to interactively install the [Haskell Toolchain](#supported-tools). These commands should be run as **non-root/non-admin
+user**.
+
+For Linux, macOS, FreeBSD or Windows Subsystem 2 for Linux, run this in a terminal:
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
+```
+
+For Windows, run this in a PowerShell session:
+
+```psh
+Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $true
+```
+
+If you want to know what these scripts do, check out the [source code at the repository](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/scripts/bootstrap). Advanced users may want to perform a [manual installation](#manual-install) and GPG verify the binaries.
+
+**Advice: Make sure to check out the [Haskell documentation](https://www.haskell.org/documentation/) after installation.**
+
+## Supported tools
+
+GHCup supports the following tools, which are also known as the **Haskell Toolchain**:
+
+1. [GHC](https://www.haskell.org/ghc/)
+2. [cabal-install](https://cabal.readthedocs.io/en/latest/)
+3. [haskell-language-server](https://haskell-language-server.readthedocs.io/en/latest/)
+4. [stack](https://docs.haskellstack.org/en/latest/README/)
+
+## Supported platforms
+
+This list may not be exhaustive and specifies support for bindists only.

+
+### Windows 7
+
+May or may not work, several issues:
+
+* [https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140)
+* [https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197)
+
+### WSL1
+
+Unsupported. GHC may or may not work. Upgrade to WSL2.
+
+### MacOS <13
+
+Not supported. Would require separate binaries, since >=13 binaries are incompatible.
+Please upgrade.
+
+### MacOS aarch64
+
+HLS bindists are still experimental. Stack is theoretically supported, but has no binaries yet.
+
+### FreeBSD
+
+Lacks some upstream bindists and may need compat libs, since most bindists are built on FreeBSD-12.
+HLS bindists are experimental.
+
+### Linux ARMv7/AARCH64
+
+Lower availability of bindists. HLS only has experimental ones. Stack not supported currently.
+
+## Manual install
+
+Download the binary for your platform at [https://downloads.haskell.org/~ghcup/](https://downloads.haskell.org/~ghcup/)
+and place it into your `PATH` anywhere.
+
+If you want to GPG verify the binaries, import the following key first: `7784930957807690A66EBDBE3786C5262ECB4A3F`.
+
+Then adjust your `PATH` in `~/.bashrc` (or similar, depending on your shell) like so:
+
+```sh
+export PATH="$HOME/.cabal/bin:$HOME/.ghcup/bin:$PATH"
+```
