# GHC up
|
|
|
|
Installs a specified GHC version into `~/.ghcup/ghc/<ver>`,
|
|
and places `ghc-<ver>` etc. symlinks in `~/.ghcup/bin/`.
|
|
Additionally allows to manage currently selected ghc
|
|
via unversioned symlinks.
|
|
|
|
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).

## Why
|
|
|
|
I don't use stack, but `cabal new-*` and system GHC versions
|
|
are often either outdated or cannot be installed in parallel
|
|
with proper symlink management.
|
|
|
|
Inspired by [rustup](https://github.com/rust-lang-nursery/rustup.rs).
|
|
|
|
## Installation
|
|
|
|
Just place the `ghcup` shell script into your PATH anywhere
|
|
(preferably `~/.local/bin`).
|
|
|
|
## Usage
|
|
|
|
See `ghcup --help`.
|
|
|
|
## Contributing
|
|
|
|
* PR or email
|
|
* this script is POSIX shell
|
|
* use [shellcheck](https://github.com/koalaman/shellcheck) and `checkbashisms.pl` from [debian devscripts](http://http.debian.net/debian/pool/main/d/devscripts/devscripts_2.18.4.tar.xz)
|

* whitespaces, no tabs

## TODO
|
|
|
|
- [ ] FreeBSD support ([#4](https://github.com/hasufell/ghcup/issues/4))
|
|
- [ ] Make fetching tarballs more robust ([#5](https://github.com/hasufell/ghcup/issues/5))
|
|
|
|
## Feature considerations
|
|
|
|
- [ ] Allow to compile from source ([#2](https://github.com/hasufell/ghcup/issues/2))
|
|
- [ ] Allow to install cabal-install as well ([#3](https://github.com/hasufell/ghcup/issues/3))
|
|
|
|
## Known problems
|
|
|
|
Since this uses precompiled binaries 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.
