## What is GHCup?
|
||
|
|
|
||
|
|
```sh
|
||
|
|
curl -s -L 'https://downloads.haskell.org/~ghc/9.6.5/ghc-9.6.5-x86_64-fedora33-linux.tar.xz' |
|
||
|
|
tar -xJ -C /tmp &&
|
||
|
|
cd /tmp/ghc-9.6.5-x86_64-unknown-linux/ &&
|
||
|
|
./configure --prefix="$HOME/.local" &&
|
||
|
|
make install &&
|
||
|
|
rm -rf /tmp/ghc-9.6.5-x86_64-unknown-linux/
|
||
|
|
```
|

## How it started
|
||
|
|
|
||
|
|
* 🤹 small team at work on different platforms
|
||
|
|
* 🧑💻 SHELL + POSIX
|
||
|
|
* 🦾 first version was 165 LOC
|
||
|
|
* 🙏 only installer at that time was stack
|
||
|
|
|
||
|
|
## Goals

|
|
|
||
