+# 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 filepath or directory
+
+Filepath and directory have two fundamental problems: 1. they use String as filepath (see [AFPP](https://gitlab.haskell.org/ghc/ghc/-/wikis/proposal/abstract-file-path) as to why this is wrong) and 2. they try very hard to be cross-platform at the expense of low-level correctness. Instead, we use the [hpath](https://github.com/hasufell/hpath) libraries for file and filepath related stuff, which also gives us stronger filepath types.
+
+### 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.

+
+## Installation
+
+### Simple bootstrap
+
+Follow the instructions at [https://www.haskell.org/ghcup/](https://www.haskell.org/ghcup/)
+
+### 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"
+```
+
+## Usage
+
+See `ghcup --help`.
+
+Common use cases are:
+
+```sh
+# list available ghc/cabal versions
+ghcup list
+
+# install the recommended GHC version
+ghcup install
+
+# install a specific GHC version
+ghcup install 8.2.2
+
+# set the currently "active" GHC version
+ghcup set 8.4.4
+
+# install cabal-install
+ghcup install-cabal
+
+# update ghcup itself
+ghcup upgrade
+```
+
+Generally this is meant to be used 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.
+
+### 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.
+
+## 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 users
+
+* [vabal](https://github.com/Franciman/vabal)
+
+## Known problems
+
+### 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.
+
+## FAQ
+
+1. 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.
+
+2. Why not support windows?
+
+Consider using [Chocolatey](https://chocolatey.org/search?q=ghc) or [ghcups](https://github.com/kakkun61/ghcups).
+
+3. Why the haskell reimplementation?
+
+Why not?

+# RELEASING
+
+1. update `GHCup.Version` module. `ghcupURL` must only be updated if we change the `_toolRequirements` type or the JSON representation of it. The version of the json represents the change increments. `ghcUpVer` is the current application version.
+
+2. Add/fix downloads to `GHCupDownloads` module, then run `ghcup-gen gen` to generate the new json and validate it via `ghcup-gen check`.
+
+3. Commit and git push with tag. Wait for tests to succeed.
+
+4. Upload the new `ghcup-<ver>.json` to `webhost.haskell.org/ghcup/data/`.
+
+5. Build ghcup releases for Linux (fully static), mac (with `-fcurl`) and FreeBSD (with `-fcurl`). Upload to `webhost.haskell.org/ghcup/bin/` and update symlinks.

 ## Now
 
-* ghcup init?
-* merge two download files
-* fetch/unpack functionality
-* installing multiple versions of the same
-* post-install
-
-* proper test suite
-
-* !! update of 0.1.5 must go in ghcup-0.0.1.json !!
-
-* try to run exe before upgrade (backup to ~/.ghcup/bin/ghcup.old)
-* stdout flushing?
-* resume support (for make-install only)
+* move out GHCup.Version module, bc it's not library-ish
 
 ## Maybe
 
-* version ranges in json
+* maybe: changelog          Show the changelog of a GHC release (online)
 * sign the JSON? (Or check gpg keys?)
 * testing (especially distro detection -> unit tests)
 
 ## Later
 
+* i386 support
 * add support for RC/alpha/HEAD versions
 
 ## Cleanups
 
+* too many decodeutf8
 * avoid alternative for IO
 * use plucky or oops instead of Excepts
 
 ## Questions
 
-* move out GHCup.Version module, bc it's not library-ish?
 * mirror support
 * interactive handling when distro doesn't exist and we know the tarball is incompatible?
 * ghcup-with wrapper to execute a command with a given ghc in PATH?

-## 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
-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?
-
-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 [ghcup-metadata](https://github.com/haskell/ghcup-metadata) repository.
-
-## 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
-
-Head over to: [https://github.com/haskell/ghcup-metadata#adding-a-new-ghc-version](https://github.com/haskell/ghcup-metadata#adding-a-new-ghc-version)
-
-### 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)
-
-Every subcommand now lives in its own module under [GHCup.OptParse.MyCommand](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/app/ghcup/GHCup/OptParse).
-
-## 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.
-3. This refactor split up the huge `Main.hs` and put every subcommand in its own module: [#212](https://gitlab.haskell.org/haskell/ghcup-hs/-/merge_requests/212)
-
-# Releasing
-
-1. Update version in `ghcup.cabal`
-
-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. If a new ghcup yaml version is needed, create one at [ghcup-metadata repo](https://github.com/haskell/ghcup-metadata) and push to a temporary release branch, then update the `data/metadata` submodule in ghcup-hs repo to that branch, so CI can pass
-
-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 (also check `scripts/releasing/pull_release_artifacts.sh` and `scripts/releasing/sftp-upload-artifacts.sh`)
-
-7. Add ghcup release artifacts to ALL yaml files, see [ghcup-metadata repo](https://github.com/haskell/ghcup-metadata)
-
-8. Upload the final `ghcup-<ver>.yaml` (and a detached GPG sig of it) to `webhost.haskell.org/ghcup/data/` (for yaml versions <= 0.0.6) as well as [https://github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata) (for all versions).
-
-9. Update version in `scripts/bootstrap/bootstrap-haskell` (`ghver` variable at the top of the script)
-
-10. Upload `scripts/bootstrap/bootstrap-haskell` and `scripts/bootstrap/bootstrap-haskell.ps1` to `webhost.haskell.org/ghcup/sh/`
-
-11. Update the top-level ghcup symlinks at `downloads.haskell.org/~ghcup` (see `scripts/releasing/sftp-symlink-artifacts.sh`)
-
-12. Update the `data/metadata` submodule in ghcup-hs repo to master
-
-13. Do hackage release
-
-14. Post on reddit/discourse/etc. and collect rewards
-
-# Documentation
-
-This documentation page is built via [mkdocs](https://www.mkdocs.org/), see `mkdocs.yml` and `docs/` subfolder.
-The module graph needs [graphmod](https://github.com/yav/graphmod) and is generated via `scripts/dev/modgraph.sh`.

-# User Guide
-
-This is a more in-depth guide specific to GHCup. `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
-```
-
-### Tags and shortcuts
-
-GHCup has a number of tags and version shortcuts, that can be used as arguments to **install**/**set** etc.
-All of the following are valid arguments to `ghcup install ghc`:
-
-* `latest`, `recommended`
-* `base-4.15.1.0`
-* `9.0.2`, `9.0`, `9`
-
-If the argument is omitted, the default is `recommended`.
-
-## 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).
-
-# 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.
-
-## 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
-
-### 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.**
-
-## Caching
-
-GHCup has a few caching mechanisms to avoid redownloads. All cached files end up in `~/.ghcup/cache` by default.
-
-### Downloads cache
-
-Downloaded tarballs (such as GHC, cabal, etc.) are not cached by default unless you pass `ghcup --cache` or set caching
-in your [config](#configuration) via `ghcup config set cache true`.
-
-### Metadata cache
-
-The metadata files (also see [github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata))
-have a 5 minutes cache per default depending on the last access time of the file. That means if you run
-`ghcup list` 10 times in a row, only the first time will trigger a download attempt.
-
-### Clearing the cache
-
-If you experience problems, consider clearing the cache via `ghcup gc --cache`.
-
-## Metadata
-
-The metadata are the files that 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)
-
-### 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"
-```
-
-See [config.yaml](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/data/config.yaml)
-for more options.
-
-Alternatively you can do it via a cli switch:
-
-```sh
-ghcup --url-source=https://some-url/ghcup-0.0.6.yaml list
-```
-
-#### Known mirrors
-
-1. [https://mirror.sjtu.edu.cn/docs/ghcup](https://mirror.sjtu.edu.cn/docs/ghcup)
-
-### (Pre-)Release channels
-
-A release channel is basically just a metadata file location. You can add additional release
-channels that complement the default one, such as the **prerelease channel** like so:
-
-```sh
-ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
-```
-
-This will result in `~/.ghcup/config.yaml` to contain this record:
-
-```yml
-url-source:
-  AddSource:
-  - Right: https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.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: []
-```
-
-If you want to combine your release channel with a mirror, you'd do it like so:
-
-```yml
-url-source:
-  OwnSource:
-  # base metadata
-  - "https://mirror.sjtu.edu.cn/ghcup/yaml/ghcup/data/ghcup-0.0.6.yaml"
-  # prerelease channel
-  - "https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml"
-```
-
-# More on installation
-
-## 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).
-
-## 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.
-
-## 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)
-
-### github workflows
-
-On github workflows you can use [https://github.com/haskell/actions/](https://github.com/haskell/actions/).
-GHCup itself is also pre-installed on all platforms, but may use non-standard install locations.
-
-## 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>`.
-   
-# Tips and tricks
-
-## ghcup run
-
-If you don't want to explicitly switch the active GHC all the time and are using
-tools that rely on the plain `ghc` binary, GHCup provides an easy way to execute
-commands with a certain toolchain prepended to PATH, e.g.:
-
-```sh

-# 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 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
-```
-
-There's also a [youtube video](https://www.youtube.com/watch?v=bB4fmQiUYPw) explaining installation on windows.
-
-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.
-
-### Which versions get installed?
-
-GHCup has two main channels for every tool: **recommended** and **latest**. By default, it installs *recommended*.
-
-*latest* follows the latest release of every tool, while *recommended* is at the discretion of the GHCup maintainers and based on community adoption (hackage libraries, tools like HLS, stackage support, etc.) and known bugs.
-
-Also see [tags and shortcuts](../guide/#tags-and-shortcuts) for more information.
-
-## 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*.
-
-## Supported tools
-
-GHCup supports the following tools, which are also known as the **Haskell Toolchain**:

-
-### 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 <10.13
-
-Not supported. Would require separate binaries, since >=10.13 binaries are incompatible.
-Please upgrade.
-
-### MacOS aarch64
-
-HLS bindists are still experimental. Stack has only unofficial binaries for this platform.
-There are various issues with GHC itself.
-
-### 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. Stack and HLS binaries are experimental.
-
-## 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"
-```

-# 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/latest/docs/html/users_guide/9.2.2-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).
