 # Revision history for ghcup
 
-## 0.1.19.5 -- ????-?-??
+## 0.1.22.0 -- 2024-03-13
 
-* support JS cross compilers wrt [#838](https://github.com/haskell/ghcup-hs/issues/838)
+### New features
+
+* A help screen/tutorial in the TUI by @lsmor (Luis Morillo)
+* Beef up `--overwrite-version`, fixes [#998](https://github.com/haskell/ghcup-hs/issues/998)
+  * e.g. `ghcup compile hls -g master --overwrite-version='%v-%h' --ghc 9.4.8` will produce a binary called `haskell-language-server-wrapper-<version-from-cabal-file>-<short-git-commit-hash>`... refer to `ghcup compile hls --help` for more information
+* Allow to set ghcup msys2 environment wrt [#982](https://github.com/haskell/ghcup-hs/issues/982)
+* Add mechanism to warn on new metadata versions, fixes [#860](https://github.com/haskell/ghcup-hs/issues/860)
+* Add pre-install message support via ghcup metadata, wrt [#1016](https://github.com/haskell/ghcup-hs/issues/1016)
+* Allow to remove all unset versions, fixes [#1019](https://github.com/haskell/ghcup-hs/issues/1019)
+  * e.g.: `ghcup gc --unset`
+
+### Improvements and bug fixes
+
+* Fix potential [HSEC-2024-0002](https://haskell.github.io/security-advisories/advisory/HSEC-2024-0002.html)
+* Fix TUI crash in windows terminal 1.19 [#1013](https://github.com/haskell/ghcup-hs/issues/1013)
+* Clean up on git clone errors, fixes [#1004](https://github.com/haskell/ghcup-hs/issues/1004)
+* Error out on empty UserSettings wrt [#922](https://github.com/haskell/ghcup-hs/issues/922)
+* Fix failure mode when metadata is garbage, fixes [#921](https://github.com/haskell/ghcup-hs/issues/921)
+* Be less confusing when user tries to 'set' ghcup in TUI, fixes [#923](https://github.com/haskell/ghcup-hs/issues/923)
+* Fix prefetch for cross bindists
+* Fix misinterpretation of '+' in URI paths, fixes [#408](https://github.com/haskell/ghcup-hs/issues/408)
+* Stricter (and better) file uri handling
+* Set LD=ld.bfd on Alpine linux during bindist configure
+* Add rocky/void detection
+* Logging improvements
+* Remove the "show all tool" config in the TUI
+* Fix opening changelog on windows
+* Don't remove share dir link prematurely
+* Require user to explicitly choose subcommand for 'ghcup config'
+* Don't download twice when trying stack decoding
+
+### Refactoring and maintenance
+
+* Large TUI code cleanup by @lsmor (Luis Morillo)... more coming up soon
+* Allow building with `tar` instead of `libarchive` (mainly to make contributions easier)
+
+## 0.1.20.0 -- 2023-11-10
+
+### 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)

+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

+### 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
 ```

+
+```sh
+stack config set install-ghc false --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"

+```
+
+#### 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.

@@ -400,6 +507,78 @@ 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.
 
+Since ghcup version 0.1.20.0, we provide cross bindists for GHC JS and WASM. These can be installed conveniently.
+However, these are intended as a developer preview only. By using these GHC variants, you are implicitly signing up to participate in GHC development!
+If you run into bugs or missing behavior, join the dev chat at https://matrix.to/#/#GHC:matrix.org.
+
+First, add the cross release channel:
+
+```sh
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/develop/ghcup-cross-0.0.8.yaml
+```
+
+The next sections explain how to install each cross bindist.
+
+### GHC JS cross bindists (experimental)
+
+You need the required emscripten JS toolchain:
+
+```sh
+git clone https://github.com/emscripten-core/emsdk.git
+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).
+
+To install we need to invoke ghcup like so:
+
+```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
+```
+
+**Note that some wasm bindists don't work with the master branch of ghc-wasm-meta. GHCup will warn you about such cases prior to installation and point you to the right commit.**
+
+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

+This module contains the BrickState. One could be tempted to include this data structure in GHCup.Brick.Common,
+but it is better to make a separated module in order to avoid cyclic dependencies.
+
+This happens because the BrickState is sort of a container for all widgets,
+but widgets depends on common functionality, hence:
+
+             BrickState `depends on` Widgets.XYZ `depends on` Common
+
+The linear relation above breaks if BrickState is defined in Common.

+
+A general system inspired by Brick.Form. It uses optics instead of microlenses and it is less generic than
+Brick.Form, but generic enough to serve our purpose.
+
+A Menu consists in
+  a) A state value
+  b) A list of fields. Each field is capable of modifying a part of the state
+  c) some metadata
+
+A field (type MenuField) consists in
+  a) a Lens to a part of the Menu state, so the Menu can call that lens to modify its own state
+  b) an input widget
+
+An input (type FieldInput) consist in
+  a) some state
+  b) a validator function
+  c) a handler and a renderer
+
+We have to use existential types to achive a composable API since every FieldInput has a different
+internal type, and every MenuField has a different Lens. For example:
+  - The menu state is a record (MyRecord {uri: URI, flag : Bool})
+  - Then, there are two MenuField:
+    - One MenuField has (Lens' MyRecord URI) and the other has (Lens' MyRecord Bool)
+    - The MenuFields has FieldInputs with internal state Text and Bool, respectively
+  - Obviously, the MenuField has to be polimorphic in the Lens' and in the Input internal state,
+    But we must hide that polimorphisim (existential), in order to store all MenuField in a List
