# What is this fork?
|
|
|
|
This fork contains a patched version of GHCJS 8.10 which improves performance and memory usage.
|
|
|
|
For more info see this PR: https://github.com/input-output-hk/haskell.nix/pull/1306
|
|
|
|
## Package versions
|
|
|
|
This branch is updated every day with commits from https://github.com/input-output-hk/haskell.nix/tree/master. This means that it receives all of the updates the initial project does.
|
|
|
|
## Caching
|
|
|
|
Building the patched compiler itself takes around 2-3 hours. The [Typeable](https://typeable.io) public nix cache probably has a cached version of the compiler. You can follow these instruction to set it up: [app.cachix.org/organization/typeable/cache/typeable](https://app.cachix.org/organization/typeable/cache/typeable).

`haskell.nix` can automatically translate your Cabal or Stack project and
|
|
its dependencies into Nix code.

## Help! Something isn't working
|
|
|
|
The #1 problem that people have when using `haskell.nix` is that they find themselves building GHC.
|
|
This should not happen, but you *must* follow the `haskell.nix` setup instructions properly to avoid it.
|
|
If you find this happening to you, please check that you have followed the
|
|
[getting started instructions](https://input-output-hk.github.io/haskell.nix/tutorials/getting-started.html#setting-up-the-binary-cache) and
|
|
consult the corresponding [troubleshooting section](https://input-output-hk.github.io/haskell.nix/troubleshooting.html#why-am-i-building-ghc).
|
|
|
|
The troubleshooting documentation also contains some help for other common issues.
|
|
Please give it a read before asking on IRC or opening an issue.
|
|
|
|
If you're still stuck, join the [#haskell.nix](https://www.irccloud.com/invite?channel=%23haskell.nix&hostname=irc.libera.chat&port=6697&ssl=1) channel on [irc.libera.chat](https://libera.chat/), or open an issue.

## Related repos
|
|
|
|
The `haskell.nix` repository contains the runtime system for building
|
|
Haskell packages in Nix. It depends on other repos, which are:
|
|
|
|
- [`nix-tools`](https://github.com/input-output-hk/nix-tools) — provides the programs for generating Nix expressions from Haskell projects.
|
|
|
|
- [`hackage.nix`](https://github.com/input-output-hk/hackage.nix) — the latest contents of the [Hackage](https://hackage.haskell.org/) databases, converted to Nix expressions.
|
|
|
|
- [`stackage.nix`](https://github.com/input-output-hk/stackage.nix) — all of the [Stackage](https://www.stackage.org/) snapshots, converted to Nix expressions.
