 # Revision history for ghcup
 
-## 0.1.20.0 -- 2023-11-10
+## 0.1.17.6 -- ????-??-??
-
-### New features
-
-* support TUI on windows thanks to the work from vty and brick maintainers (Chris Hackett, Timofey Zakrevskiy, Jonathan Daugherty, ...), wrt [#912](https://github.com/haskell/ghcup-hs/pull/912)
-* support JS and wasm cross compilers wrt [#838](https://github.com/haskell/ghcup-hs/issues/838), thanks to Sylvain Henry and IOG
-* Support stacks installation strategy and metadata wrt [#892](https://github.com/haskell/ghcup-hs/issues/892)
-  - you can now enable stacks installation method via `ghcup config set url-source '["GHCupURL", "StackSetupURL"]'`... for more information, check the [documentation](https://www.haskell.org/ghcup/guide/#using-stacks-setup-info-metadata-to-install-ghc)
-
-### Improvements and bug fixes
-
-* fix segfault in TUI when hitting enter early wrt [#887](https://github.com/haskell/ghcup-hs/issues/887)
-* Improve key handling in TUI, fixes [#875](https://github.com/haskell/ghcup-hs/issues/875)
-* add explicit support for Void Linux and Rocky Linux (this requires a metadata version bump to `ghcup-0.0.8.yaml`)
-* optparse cli interface now has a test suite thanks to Lei Zhu, wrt [#862](https://github.com/haskell/ghcup-hs/pull/862)
-

-* Make armv7/aarch64 linux binaries more portable (built on Debian buster)
-* Improve usability on 'ghcup config add-release-channel', fixes [#751](https://github.com/haskell/ghcup-hs/issues/751)
-* Make version shortcuts work with 'ghcup set', fixes [#757](https://github.com/haskell/ghcup-hs/issues/757)

-* allow to overwrite distro detection via config wrt [#421](https://github.com/haskell/ghcup-hs/issues/421)
-    - this is particularly useful for e.g. Ubuntu derivates, where ghcup doesn't pick the optimal bindist, also see the [GHCup documentation on overriding distro detection](https://www.haskell.org/ghcup/guide/#overriding-distro-detection)
-* Add proper support for mirrors wrt [#357](https://github.com/haskell/ghcup-hs/issues/357)

-
-* Fix tui set wrt [#266](https://gitlab.haskell.org/haskell/ghcup-hs/-/merge_requests/266) by Arjun Kathuria
-    - Ask the user to install the tool via prompt when setting an non-installed version
-* improvements to safe (un-)installations
-    - bindists that don't support `make DESTDIR=/some/tmp/dir install` are now unsupported
-    - installed GHC files are now recorded to avoid use of `removePathForcibly`

-    - print the long hash in addition to the detected version
-* Improve `ghcup compile hls`
-    - add `--git-describe-version` switch as an alternative to `--overwrite-version`
-    - Allow to build HLS from hackage (now is the default)
-	- Allow to run 'cabal update' automatically before the HLS build
-	- Fix parser and completer for 'ghcup compile hls --version'
-* Improve `ghcup compile ghc`

-## Distribution policies
-
-Like most Linux distros and other distribution channels, GHCup also
-follows certain policies. These are as follows:
-
-1. The end-user experience is our primary concern
-    - ghcup in CI systems as a use case is a first class citizen
-2. We strive to collaborate with all maintainers of all the tools we support and maintain a good relationship
-3. We may fix build system or other distribution bugs in upstream bindists
-    - these are always communicated upstream
-4. We may even patch source code of supported tools in very rare cases if that is required to ensure that the end-user experience does not break
-    - we'll first try to upstream any such required patch and request a new release to avoid downstream patching
-    - patches will be communicated to the maintainers either way and we'll strive to get their review
-    - they will also be communicated to the end-user
-    - they will be uploaded along with the bindist
-    - we will avoid maintaining long-running downstream patches (currently zero)
-5. We may add bindists for platforms that upstream does not support
-    - this is currently the case for GHC for e.g. Alpine and possibly FreeBSD in the future
-    - this is currently also the case for stack on darwin M1
-    - we don't guarantee for unofficial bindists that the test suite passes at the moment (this may change in the future)
-6. We GPG sign all the GHCup metadata as well as the unofficial bindists
-    - any trust issues relating to missing checksums or GPG signatures is a bug and given high priority

 ## FAQ
 
-### Is ghcup really the main installer?
-
-This is based on the Haskell survey results from 2022, which show that more
-than half of survey participants use GHCup: https://taylor.fausak.me/2022/11/18/haskell-survey-results/
-
 ### Why reimplement stack?

-* `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
-
-On windows, there's additionally:
-
-* `GHCUP_MSYS2`: Has to point to the root of an existing MSYS2 installation (when installed by GHCup, that's e.g. `C:\ghcup\msys64`). GHCup bootstrap takes care of this usually.
-
-### 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`)

-## Metadata
+## Compiling GHC from source
-
-Metadata files are also called release or distribution channels. They describe tool versions, where to download them etc. and
-can be viewed here: [https://github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata).
-
-See the [description](https://github.com/haskell/ghcup-metadata#metadata-variants-distribution-channels)
-of metadata files to understand their purpose. These can be combined.
-
-For example, if you want access to both prerelease and cross bindists, you'd do:
-
-```sh
-ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
-ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-cross-0.0.8.yaml
-```
-
-This results in the following configuration in `~/.ghcup/config.yaml`:
-
-```yaml
-url-source:
-# the base url that contains all the release bindists
-- GHCupURL
-# prereleases
-- https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.8.yaml
-# cross bindists
-- https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-cross-0.0.8.yaml
-```
-
-You can add as many channels as you like. They are combined under *Last*, so versions from the prerelease channel
-here overwrite the default ones, if any.
-
-To remove the channel, delete the entire `url-source` section or set it back to the default:
-
-```yml
-url-source:
-  - GHCupURL
-```
-
-Also see [config.yaml](https://github.com/haskell/ghcup-hs/blob/master/data/config.yaml)
-for more options.
-
-You can also use an alternative metadata via one-shot cli option:
-
-```sh
-ghcup --url-source=https://some-url/ghcup-0.0.8.yaml tui
-```
-
-One main caveat of using URLs is that you might need to check whether there are new versions
-of the file (e.g. `ghcup-0.0.7.yaml` vs `ghcup-0.0.8.yaml`). Although old metadata files
-are supported for some time, they are not so indefinitely.
-
-### Mirrors
-
-Metadata files can also be used to operate 3rd party mirrors, in which case you want to use
-a URL instead of the `GHCupURL` alias. E.g. in `~/.ghcup/config.yaml`, you'd do:
-
-```yml
-url-source:
-  - https://mirror.sjtu.edu.cn/ghcup/yaml/ghcup/data/ghcup-0.0.6.yaml
-```
-
-Note that later versions of GHCup allow more sophisticated mirror support, see [here](./#mirrors-proper).
-
-#### Known mirrors
-
-1. [https://mirror.sjtu.edu.cn/docs/ghcup](https://mirror.sjtu.edu.cn/docs/ghcup)
-2. [https://mirrors.ustc.edu.cn/help/ghcup.html](https://mirrors.ustc.edu.cn/help/ghcup.html)
-
-### Git based metadata config
-
-If you don't like the way ghcup updates its metadata with caching and fetching via curl, you can also do as follows:
-
-Clone the metadata git repo:
-
-```sh
-mkdir -p /home/user/git/
-cd /home/user/git/
-git clone -b master https://github.com/haskell/ghcup-metadata.git
-```
-
-Then tell ghcup to use file locations in `~/.ghcup/config.yaml`, e.g.:
-
-```yaml
-url-source:
-- file:///home/user/git/ghcup-metadata/ghcup-0.0.8.yaml
-- file:///home/user/git/ghcup-metadata/ghcup-cross-0.0.8.yaml
-- file:///home/user/git/ghcup-metadata/ghcup-prereleases-0.0.8.yaml
-```
-
-Now, if you invoke `ghcup tui`, it will open instantly without any download, since it just
-reads the metadata from local disk.
-
-You'll have to update the metadata manually though, like so:
-
-```sh
-cd /home/user/git/
-git pull --ff-only origin master
-```
-
-## Stack integration
-
-Stack manages GHC versions internally by default. In order to make it use ghcup installed
-GHC versions there are two strategies.
-
-### Strategy 1: Stack hooks (new, recommended)
-
-Since stack 2.9.1 you can customize the installation logic of GHC completely, see [https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation](https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation).
-
-We can use this to simply invoke ghcup whenever stack is trying to install/discover a GHC versions. This
-is done via placing a shell script at `~/.stack/hooks/ghc-install.sh` and making it executable.
-
-The ghcup bootstrap script asks you during installation whether you want to install this shell script. You can also
-install/update it manually like so:
-
-```sh
-mkdir -p ~/.stack/hooks/
-curl https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/hooks/stack/ghc-install.sh \
-  > ~/.stack/hooks/ghc-install.sh
-chmod +x ~/.stack/hooks/ghc-install.sh
-# hooks are only run when 'system-ghc: false'
-stack config set system-ghc false --global
-```
-
-By default, when the hook fails for whatever reason, stack will fall back to its own installation logic. To disable
-this, run `stack config set install-ghc false --global`.
-
-### Strategy 2: System GHC (works on all stack versions)
-
-You can instruct stack to use "system" GHC versions (whatever is in PATH). To do so,
-run the following commands:
-
-```sh
-stack config set install-ghc false --global
-stack config set system-ghc  true  --global
-```
-
-### Using stack's setup-info metadata to install GHC
-
-You can now use stack's [setup-info metadata](https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml)
-to install GHC. For that, you can invoke ghcup like so as a shorthand:
-
-```sh
-# ghcup will only see GHC now
-ghcup -s StackSetupURL install ghc 9.4.7
-# this combines both ghcup and stack metadata
-ghcup -s '["GHCupURL", "StackSetupURL"]' install ghc 9.4.7
-```
-
-To make this permanent and combine it with the GHCup metadata, you can add the following to your `~/.ghcup/config.yaml`:
-
-```yaml
-url-source:
-  - GHCupURL
-  # stack versions take precedence
-  # you'll still have access to GHCup provided versions and tools in case they don't exist in stack metadata
-  - StackSetupURL
-```
-
-You can customize or add sections to the setup-info similar to how the [stack documentation](https://docs.haskellstack.org/en/stable/yaml_configuration/#setup-info) explains it. E.g. to change the 9.4.7 bindist, you might do:
-
-```yaml
-url-source:
-  - GHCupURL
-  - StackSetupURL
-  - setup-info:
-      ghc:
-        linux64-tinfo6:
-          9.4.7:
-            url: "https://downloads.haskell.org/~ghc/9.4.7/ghc-9.4.7-x86_64-fedora27-linux.tar.xz"
-            content-length: 179117892
-            sha256: 216b76b7c6383e6ad9ba82533f323f8550e52893a8b9fa33c7b9dc4201ac766a
-```
-
-#### Caveats
-
-The main caveat with using this method is that there's no guarantee that GHCup will pick a compatible HLS bindist
-when you try to install HLS.
-
-Another potential usability issue is that the `latest` and `recommended` shorthands won't work anymore, since
-Stack metadata doesn't have a concept of those and we don't try to be smart when combining the metadatas.
-
-### Windows
-
-On windows, you may find the following config options useful too:
-`skip-msys`, `extra-path`, `extra-include-dirs`, `extra-lib-dirs`.
-
-Also check out: [https://docs.haskellstack.org/en/stable/yaml_configuration](https://docs.haskellstack.org/en/stable/yaml_configuration)
-
-## Mirrors (proper)
-
-Mirrors are now supported via configuration, instead of specifying alternative metadata files.
-
-As an example, this would be a complete mirror configuration in `~/.ghcup/config.yaml`:
-
-```yaml
-mirrors:
-  # yaml download location, would result in:
-  #      https://raw.githubusercontent.com/haskell/ghcup-metadata/develop/ghcup-0.0.8.yaml
-  #   -> https://mirror.sjtu.edu.cn/ghcup/yaml/haskell/ghcup-metadata/master/ghcup-0.0.8.yaml
-  "raw.githubusercontent.com":
-    authority:
-      host: "mirror.sjtu.edu.cn"
-    pathPrefix: "ghcup/yaml"
-  # for stack and some older HLS versions, would result in e.g.
-  #      https://github.com/haskell/haskell-language-server/releases/download/1.2.0/haskell-language-server-Windows-1.2.0.tar.gz
-  #   -> https://mirror.sjtu.edu.cn/ghcup/github/haskell/haskell-language-server/releases/download/1.2.0/haskell-language-server-Windows-1.2.0.tar.gz
-  "github.com":
-    authority:
-      host: "mirror.sjtu.edu.cn"
-    pathPrefix: "ghcup/github"
-  # for all haskell.org hosted bindists, would result in e.g.
-  #      https://downloads.haskell.org/~ghc/9.8.1/ghc-9.8.1-x86_64-deb10-linux.tar.xz
-  #   -> https://mirror.sjtu.edu.cn/ghcup/haskell-downloads/~ghc/9.8.1/ghc-9.8.1-x86_64-deb10-linux.tar.xz
-  "downloads.haskell.org":
-    authority:
-      host: "mirror.sjtu.edu.cn"
-    pathPrefix: "downloads.haskell.org"
-```
-
-The configuration depends on the host of the mirror and they have to provide the correct configuration.
-
-# More on installation
-
-## Customisation of the installation scripts
-
-The scripts offered to install GHCup are available here:
-
-* [bootstrap-haskell](https://github.com/haskell/ghcup-hs/blob/master/scripts/bootstrap/bootstrap-haskell#L7)
-  for Unix-like operating systems
-* [bootstrap-haskell.ps1](https://github.com/haskell/ghcup-hs/blob/master/scripts/bootstrap/bootstrap-haskell.ps1)
-  for Windows (PowerShell). This will, in turn, run the final bootstrap script
-  (by default, that for the Unix-like operating systems).
-
-The effect of the scripts can be customised by setting one or more
-`BOOTSTRAP_HASKELL_*` environment variables (as set out in the first script)
-and, in the case of Windows, by specifying parameters (as set out in the
-PowerShell script).
-
-For example, you can toggle:
-
-* non-interactive installation
-* a more verbose installation
-* whether to install only GHCup (and, on Windows, MSYS2)
-* not to trigger the upgrade of GHCup
-* whether to install the latest version of HLS
-* whether to install the latest version of Stack
-* whether to respect the XDG Base Directory Specification
-* whether to adjust (prepend) the PATH in `bashrc`
-* on Windows, whether to adjust MINGW paths in `cabal.config`
-
-You can also specify:
-
-* the GHC version to install
-* the Cabal version to install
-* which downloader to use (the default is `curl`)
-* the base URL for the download of the GHCup binary distribution
-
-On Windows, you can also use the parameters to:
-
-* toggle whether to overwrite a previous installation
-* specify the GHCup installation root directory
-* specify the Cabal root directory
-* specify the directory of an existing installation of MSYS2 (for example,
-  the one supplied by Stack)
-* specify the URL of the final bootstrap script
-* toggle whether to run the final bootstrap script via `bash` (instead of in a
-  new MSYS2 shell)
-
-## 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 specifying a branch (`master`): `ghcup install ghc -u 'https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-linux-fedora33-release.tar.xz?job=x86_64-linux-fedora33-release' head`
-    - example specifying a job id (`1129565`): `ghcup install ghc -u ' https://gitlab.haskell.org/api/v4/projects/1/jobs/1129565/artifacts/ghc-x86_64-linux-alpine3_12-validate+fully_static.tar.xz' mr7847`
-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).
-
-## Compiling from source

-### GHC
 
 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.

+in [data/build_mk](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/data/build_mk), copy them somewhere, adjust them and

 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).
 
-### HLS
+### Cross support
 
-There are 3 main ways to compile HLS from source.
+ghcup can compile and install a cross GHC for any target. However, this
-
-1. from hackage (should have up to date version bounds)
-    - `ghcup compile hls --version 1.7.0.0 --ghc 9.2.3`
-2. from git (allows to build latest sources and PRs)
-    - `ghcup compile hls --git-ref master --ghc 9.2.3`
-    - `ghcup compile hls --git-ref a32db0b --ghc 9.2.3`
-    - `ghcup compile hls --git-ref 1.7.0.0 --ghc 9.2.3`
-3. from source distribution that's packaged during release from the corresponding git sources
-    - `ghcup compile hls --source-dist 1.7.0.0 --ghc 9.2.3`
-
-All these use `cabal v2-install` under the hood, so all build components are cached.
-You can pass arbitrary arguments to cabal, e.g. set the index state like so:
-
-```sh
-ghcup compile hls --git-ref master --ghc 9.2.3 -- --index-state=2022-06-12T00:00:00Z --allow-newer
-```
-
-You can pass `--ghc <ver>` multiple times to install for many GHCs at once.
-
-When building from git sources, ghcup will auto-detect the HLS version that the git commit corresponds to
-from the `haskell-language-server.cabal` file. This version might not have been updated since the last release.
-If you want to avoid overwriting the existing installed HLS version, you can instruct ghcup to use `git describe`
-to set the HLS version instead:
-
-```sh
-ghcup compile hls --git-ref master --ghc 9.2.3 --git-describe-version
-```
-
-You can also set the version explicitly:
-
-```sh
-ghcup compile hls --git-ref master --ghc 9.2.3 --overwrite-version 1.7.0.0-p1
-```
-
-To instruct cabal to run `cabal update` before building, run `ghcup compile hls --version 1.7.0.0 --ghc 9.2.3 --cabal-update`
-
-As always, check `ghcup compile hls --help`.
-
-#### Updating HLS for a new GHC version
-
-First try to build from hackage with some tricks:
-
-```sh
-ghcup compile hls --version 1.7.0.0 --ghc 9.2.4 --cabal-update -- --allow-newer --index-state=2022-06-12T00:00:00Z
-```
-
-This augments the currently installed 1.7.0.0 official bindists in ghcup with new GHC versions support.
-
-If that fails (since `--allow-newer` is quite brutal), you can install from HLS master branch (which may contain new fixes) like so:
-```
-ghcup compile hls --git-ref master --git-describe-version --ghc 8.10.7 --ghc 9.2.4 --cabal-update
-```
-
-This however will create a new HLS version in ghcup, e.g. `1.7.0.0-105-gdc682ba1`, for both 8.10.7 and 9.2.4. If you want to switch back to the official bindists, run `ghcup set hls 1.7.0.0`.

+
+## 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).
+
+## Mirrors
+
+GHCup allows to use custom mirrors/download-info hosted by yourself or 3rd parties.
+
+To use a mirror, set the following option in `~/.ghcup/config.yaml`:
+
+```yml
+url-source:
+  # Accepts file/http/https scheme
+  OwnSource: "https://some-url/ghcup-0.0.6.yaml"
 ```
 
-The next sections explain how to install each cross bindist.
+See [config.yaml](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/data/config.yaml)
+for more options.
 
-### GHC JS cross bindists (experimental)
+Alternatively you can do it via a cli switch:
-
-You need the required emscripten JS toolchain:
 
 ```sh
-git clone https://github.com/emscripten-core/emsdk.git
+ghcup --url-source=https://some-url/ghcup-0.0.6.yaml list
-cd emsdk
-./emsdk install latest
-./emsdk activate latest
-source ./emsdk_env.sh
 ```
 
-Instructions are also here: [Download and install — Emscripten 3.1.43-git (dev) documentation](https://emscripten.org/docs/getting_started/downloads.html).
+### Known mirrors
 
-To install we need to invoke ghcup like so:
+1. [https://mirror.sjtu.edu.cn/docs/ghcup](https://mirror.sjtu.edu.cn/docs/ghcup)
-
-```sh
-emconfigure ghcup install ghc --set javascript-unknown-ghcjs-9.6.2
-```
-
-You'll now have the compiler `javascript-unknown-ghcjs-ghc`. To build a hello world, do e.g.:
-
-```sh
-echo 'main = putStrLn "hello world"' > hello.hs
-javascript-unknown-ghcjs-ghc -fforce-recomp hello.hs
-./hello
-```
-
-You can follow the instructions [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/javascript-backend/building#compiling-hello-world).
-
-### GHC WASM cross bindists (experimental)
-
-You need the required wasm toolchain:
-
-```sh
-git clone https://gitlab.haskell.org/ghc/ghc-wasm-meta.git
-cd ghc-wasm-meta/
-export SKIP_GHC=yes
-./setup.sh
-source ~/.ghc-wasm/env
-```
-
-To install, we need to invoke ghcup like so also passing the `--host=<host>` flag (adjust as needed):
-
-```sh
-ghcup install ghc --set wasm32-wasi-9.6.3.20230927 -- --host=x86_64-linux --with-intree-gmp --with-system-libffi
-```
-
-Also check the documentation here: [Glasgow Haskell Compiler / ghc-wasm-meta](https://gitlab.haskell.org/ghc/ghc-wasm-meta).
-
-You'll now have the compiler `wasm32-wasi-ghc`. To build a hello world, do e.g.:
-
-```sh
-echo 'main = putStrLn "hello world"' > hello.hs
-wasm32-wasi-ghc hello.hs -o hello.wasm
-wasmtime ./hello.wasm
-```
 
 ## Isolated installs
 
-**Before using isolated installs, make sure to have at least GHCup version 0.1.17.8!**
-
 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.

-# Troubleshooting
-
-## Script immediately exits on windows
-
-There are two possible reasons:
-
-1. your company blocks the script (some have a whitelist)... ask your administrator
-2. your Antivirus or Windows Defender interfere with the installation. Disable them temporarily.
-
-## C compiler cannot create executables
-
-### Darwin
-
-You need to update your XCode command line tools, e.g. [like this](https://stackoverflow.com/questions/34617452/how-to-update-xcode-from-command-line).
-
-## Certificate authority errors (curl)
-
-If your certificates are outdated or improperly configured, curl may be unable
-to download ghcup.
-
-There are two known workarounds:
-
-1. Tell curl to ignore certificate errors (dangerous): `curl -k https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/bootstrap/bootstrap-haskell | GHCUP_CURL_OPTS="-k" sh`
-2. Try to use wget instead: `wget -O /dev/stdout https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/bootstrap/bootstrap-haskell | BOOTSTRAP_HASKELL_DOWNLOADER=wget sh`
-
-On windows, you can disable curl like so:
-
-```pwsh
-Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;try { Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $true,$false,$false,$false,$false,$false,$false,"","","","",$true } catch { Write-Error $_ }

-The following distro packages are required: `binutils-gold curl gcc g++ gmp-dev libc-dev libffi-dev make musl-dev ncurses-dev perl tar xz`
-
-
-### Linux (generic)
-
-#### Generic
-
-You need the following packages: curl g++ gcc gmp make ncurses realpath xz-utils. Consult your distro documentation on the exact names of those packages.
-
-### Darwin
-
-#### Generic
-
-On OS X, in the course of running ghcup you will be given a dialog box to install the command line tools. Accept and the requirements will be installed for you. You will then need to run the command again.
-On Darwin M1 you might also need a working llvm installed (e.g. via brew) and have the toolchain exposed in PATH.
-
-### FreeBSD
-
-#### Generic
-
-The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
-
-
-### Windows
-
-#### Generic
-
-On Windows, msys2 should already have been set up during the installation, so most users should just proceed. If you are installing manually, make sure to have a working mingw64 toolchain and shell.
-
-## Next steps
-
-1. Follow the [First steps guide](../steps) on how to build a "Hello world" program, use `ghc`, run an interactive REPL and create a Haskell project
-2. To understand the difference and overlap of `stack` and `cabal`, read on [here](https://gist.github.com/merijn/8152d561fb8b011f9313c48d876ceb07)
-3. To learn Haskell proper check out the links at [How to learn Haskell proper](../steps#how-to-learn-haskell-proper)
-4. To learn more about Haskell Toolchain management, check out the [ghcup user guide](./guide.md)
 
 ## Uninstallation
 
 On linux, just run `ghcup nuke`, then make sure any ghcup added lines in your `~/.bashrc` (or similar) are removed.
 
-On windows, right click on the `Uninstall Haskell.ps1` PowerShell script on your Desktop and select *Run with PowerShell*.

-    - uncomment `extra-prog-path` and set it to `C:\ghcup\bin, C:\cabal\bin, C:\msys64\mingw64\bin, C:\msys64\usr\bin`, depending on your install destinations from 1. and 2.
-6. Set up msys2 shell
-    - run `ghcup run -m -- sed -i -e 's/db_home:.*$/db_home: windows/' /etc/nsswitch.conf` to make the HOME in your msys2 shell match the one from windows
-    - make a desktop shortcut from `C:\msys64\msys2_shell.cmd`, which will allow you to start a proper msys2 shell
-    - run `ghcup run -m -- sed -i -e 's/#MSYS2_PATH_TYPE=.*/MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2.ini`

-## Esoteric distros
-
-### Void Linux
-
-Since void linux can be installed with glibc and musl, it's hard to support correctly with ghcup.
-One way to make ghcup work on **Void Linux musl** is to follow the [Overriding distro detection](../guide/#overriding-distro-detection)
-section and tell it to consider Alpine bindists only. E.g.:
-
-```sh
-curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_MINIMAL=1 sh
-source ~/.ghcup/env
-ghcup config set platform-override '{ "arch": "A_64", "platform": { "contents": "Alpine", "tag": "Linux" }, "version": "3.17" }'
-ghcup install cabal --set latest
-ghcup install ghc --set latest
-ghcup install stack --set latest
-ghcup install hls --set latest
-```

 ## Vim integration
 
 See [ghcup.vim](https://github.com/hasufell/ghcup.vim).
 
-## VSCode integration
-The developers of the Haskell Language Server offer an [extension](https://github.com/haskell/vscode-haskell) tightly integrated with the [Haskell Language Server](https://github.com/haskell/haskell-language-server). To get started:
-
-1. Install GHCup. During installation, opt in to install the Haskell Language Server (HLS).
-2. Install the extension (from VSCode: Ctrl + P and then `ext install haskell.haskell`).
-3. Make sure your project uses the GHC version installed from GHCup (otherwise HLS is likely to fail on launch):
-    - instructions for [stack](https://docs.haskellstack.org/en/stable/yaml_configuration/#system-ghc)
-
-On Linux, some users have reported an issue when VSCode is not launched from a terminal ("cannot find ghc version"). A solution is to [let HLS know about your GHCup on $PATH](https://github.com/haskell/vscode-haskell#stackcabalghc-can-not-be-found).

-# First steps
-
-In this guide we'll take a look at a few core tools that are installed
-with the Haskell toolchain, namely, `ghc`, `runghc` and `ghci`.
-These tools can be used to compile, interpret or explore Haskell programs.
-
-First, let's start by opening your system's command line interface
-and running `ghc --version` to make sure we have successfully
-installed a Haskell toolchain:
-
-```
-➜ ghc --version
-The Glorious Glasgow Haskell Compilation System, version 8.10.7
-```
-
-If this fails, consult [the Getting started page](../install) for information on
-how to install Haskell on your computer.
-
-This guide is partly based on [Gil Mizrahi's blog](https://gilmi.me/blog/post/2021/08/14/hs-core-tools).
-
-## Compiling programs with ghc
-
-Running `ghc` invokes the Glasgow Haskell Compiler (GHC), and can be used to
-compile Haskell modules and programs into native executables and libraries.
-
-Create a new Haskell source file named `hello.hs`,
-and write the following code in it:
-
-```hs
-main = putStrLn "Hello, Haskell!"
-```
-
-Now, we can compile the program by invoking `ghc` with the file name:
-
-```sh
-➜ ghc hello.hs
-[1 of 1] Compiling Main             ( hello.hs, hello.o )
-Linking hello ...
-```
-
-For more in-depth information about the files `ghc` produces,
-follow the [GHC user guide](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/using.html#getting-started-compiling-programs) guide.
-
-Now we run our program:
-
-```sh
-➜ ./hello 
-Hello, Haskell!
-```
-
-Alternatively, we can skip the compilation phase by using the command `runghc`:
-
-```sh
-➜ runghc hello.hs
-Hello, Haskell!
-```
-
-`runghc` interprets the source file instead of compiling it and does not
-create build artifacts. This makes it very useful when developing programs
-and can help accelerate the feedback loop. More information about `runghc`
-can be found in the
-[GHC user guide](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/runghc.html).
-
-### Turning on warnings
-
-The `-Wall` flag will enable GHC to emit warnings about our code.
-
-```sh
-➜ ghc -Wall hello.hs -fforce-recomp
-[1 of 1] Compiling Main             ( hello.hs, hello.o )
-
-hello.hs:1:1: warning: [-Wmissing-signatures]
-    Top-level binding with no type signature: main :: IO ()
-  |
-1 | main = putStrLn "Hello, Haskell!"
-  | ^^^^
-Linking hello ...
-```
-
-While Haskell can infer
-the types of most expressions, it is recommended that top-level definitions
-are annotated with their types.
-
-Now our `hello.hs` source file should looks like this:
-
-```hs
-main :: IO ()
-main = putStrLn "Hello, world!"
-```
-
-And now GHC will compile `hello.hs` without warnings.
-
-## An interactive environment
-
-GHC provides an interactive environment in a form of a
-Read-Evaluate-Print Loop (REPL) called GHCi.
-To enter the environment run the program `ghci`.
-
-```sh
-➜ ghci
-GHCi, version 9.0.2: https://www.haskell.org/ghc/  :? for help
-ghci> 
-```
-
-It provides an interactive prompt where Haskell expressions can be written and
-evaluated.
-
-For example:
-
-```sh
-ghci> 1 + 1
-2
-ghci> putStrLn "Hello, world!"
-Hello, world!
-```
-
-We can define new names:
-
-```sh
-ghci> double x = x + x
-ghci> double 2
-4
-```
-
-We can write multi-line code by surrounding it with `:{` and `:}`:
-
-```hs
-ghci> :{
-| map f list =
-|     case list of
-|         [] -> []
-|         x : xs -> f x : map f xs
-| :}
-ghci> map (+1) [1, 2, 3]
-[2,3,4]
-
-```
-
-We can import Haskell source files using the `:load` command (`:l` for short):
-
-```sh
-ghci> :load hello.hs
-[1 of 1] Compiling Main             ( hello.hs, interpreted )
-Ok, one module loaded.
-ghci> main
-Hello, Haskell!
-```
-
-As well as import library modules:
-
-```sh
-ghci> import Data.Bits
-ghci> shiftL 32 1
-64
-ghci> clearBit 33 0
-32
-```
-
-We can even ask what the type of an expression is using the `:type` command
-(`:t` for short):
-
-```sh
-λ> :type putStrLn
-putStrLn :: String -> IO ()
-```
-
-To exit `ghci`, use the `:quit` command (or `:q` for short)
-
-```sh
-ghci> :quit
-Leaving GHCi.
-```
-
-A more thorough introduction to GHCi can be found in the
-[GHC user guide](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/ghci.html).
-
-### Using external packages in ghci
-
-By default, GHCi can only load and use packages that are
-[included with the GHC installation](https://downloads.haskell.org/ghc/9.4.2/docs/users_guide/9.4.2-notes.html#included-libraries).
-
-However, users of the [cabal-install](https://www.haskell.org/cabal) and
-[stack](http://haskellstack.org) build tools can download and load external packages
-very easily using the following commands:
-
-cabal-install:
-
-```sh
-cabal repl --build-depends async,say
-```
-
-Stack:
-
-```sh
-stack exec --package async --package say -- ghci
-```
-
-And the modules of the relevant packages will be available for import:
-
-```sh
-GHCi, version 9.0.1: https://www.haskell.org/ghc/  :? for help
-ghci> import Control.Concurrent.Async 
-ghci> import Say
-ghci> concurrently_ (sayString "Hello") (sayString "World")
-Hello
-World
-```
-
-Stack users can also use this feature with `runghc` and `ghc` by replacing
-`ghci` in the command above, and cabal-install users can generate an
-environment file that will make `async` and `say` visible for GHC tools
-in the current directory using this command:
-
-```sh
-cabal install --lib async say --package-env .
-```
-
-Many more packages are waiting for you on [Hackage](https://hackage.haskell.org).
-
-## Creating a proper package with modules
-
-The previous methods to compile Haskell code are for quick experiments and small
-programs. Usually in Haskell, we create cabal projects, where build tools such as
-`cabal-install` or `stack` will install necessary dependencies and compile modules
-in correct order. For simplicity's sake, this section will only use `cabal-install`.
-
-To get started, run:
-
-```sh
-mkdir haskell-project
-cd haskell-project
-cabal init --interactive
-```
-
-If you let it generate a simple project with sensible defaults, then you should have these files:
-
-* `src/MyLib.hs`: the library module of your project
-* `app/Main.hs`: the entry point of your project
-* `haskell-project.cabal`: the "cabal" file, describing your project, its dependencies and how it's built
-
-To build the project, run:
-
-```sh
-cabal build
-```
-
-To run the main executable, run:
-
-```sh
-➜ cabal run
-Hello, Haskell!
-someFunc
-```
-
-### Adding dependencies
-
-Now let's add a dependency and adjust our library module. Open `haskell-project.cabal`
-and find the library section:
-
-```
-library
-    exposed-modules:  MyLib
-
-    -- Modules included in this library but not exported.
-    -- other-modules:
-
-    -- LANGUAGE extensions used by modules in this package.
-    -- other-extensions:
-    build-depends:    base ^>=4.14.3.0
-    hs-source-dirs:   src
-    default-language: Haskell2010
-```
-
-The interesting parts here are `exposed-modules` and `build-depends`.
-To add a dependency, it should look like this:
-
-```
-    build-depends:    base ^>=4.14.3.0
-	                , directory
-```
-
-Now open `src/MyLib.hs` and change it to:
-
-```hs
-module MyLib (someFunc) where
-
-import System.Directory
-
-someFunc :: IO ()
-someFunc = do
-  contents <- listDirectory "src"
-  putStrLn (show contents)
-```
-
-### Adding modules
-
-To add a module to your package, adjust `exposed-modules`, like so
-
-```
-    exposed-modules:  MyLib
-	                  OtherLib
-```
-
-then create `src/OtherLib.hs` with the following contents:
-
-```hs
-module OtherLib where
-
-otherFunc :: String -> Int
-otherFunc str = length str
-```
-
-To use this function interactively, we can run:
-
-```sh
-➜ cabal repl
-ghci> import OtherLib
-ghci> otherFunc "Hello Haskell"
-13
-```
-
-For further information about how to manage Haskell projects
-see the [Cabal user guide](https://cabal.readthedocs.io/en/stable/getting-started.html).
