# ghcup
|
||
|
|
|
||
|
|
A rewrite of ghcup in haskell.
|
||
|
|
|
||
|
|
## TODO
|
||
|
|
|
||
|
|
* create static ghcup binaries
|
||
|
|
* adjust url in GHCupDownloads
|
||
|
|
* add print-system-reqs command
|
||
|
|
|
||
|
|
## Motivation
|
||
|
|
|
||
|
|
Maintenance problems:
|
||
|
|
|
||
|
|
* platform incompatibilities regularly causing breaking bugs:
|
||
|
|
* [Mktemp not working properly on macOS](https://gitlab.haskell.org/haskell/ghcup/issues/130)
|
||
|
|
* [ln: illegal option -- T on macOS Catalina](https://gitlab.haskell.org/haskell/ghcup/issues/123)
|
||
|
|
* [Wrong tar flag on darwin](https://gitlab.haskell.org/haskell/ghcup/issues/119))
|
||
|
|
* refactoring being difficult due to POSIX sh
|
||
|
|
|
||
|
|
Benefits of a rewrite:
|
||
|
|
|
||
|
|
* Features such as installing [release candidates](https://gitlab.haskell.org/haskell/ghcup/issues/94) or [HEAD builds](https://gitlab.haskell.org/haskell/ghcup/issues/65) can be more conveniently implemented in a rewrite
|
||
|
|
* Refactoring will be easier
|
||
|
|
* Better tool support (such as linting the downloads file)
|
||
|
|
* saner downloads file format (such as JSON)
|
||
|
|
|
||
|
|
Downsides:
|
||
|
|
|
||
|
|
* building static binaries for all platforms (and possibly causing SSL/DNS problems)
|
||
|
|
* still bootstrapping those binaries via a POSIX sh script
|
||
|
|
|
||
|
|
## Goals
|
||
|
|
|
||
|
|
* Correct low-level code
|
||
|
|
* Good exception handling
|
||
|
|
* Cleaner user interface
