# TODOs and Remarks
## 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)
## Maybe
* version ranges in json
* sign the JSON? (Or check gpg keys?)
* testing (especially distro detection -> unit tests)
## Later
* add support for RC/alpha/HEAD versions
## Cleanups
* 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?

# Installation
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](./#supported-tools) from scratch.
macOS (aka Darwin), FreeBSD and Windows and can also bootstrap a fresh [Haskell developer environment](#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).

### 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)
