### Parse Haskell Code with ghc-lib-parser

Source: https://github.com/digital-asset/ghc-lib/blob/master/README.md

Use ghc-lib-parser as a potential replacement for haskell-src-exts to parse Haskell code. Refer to the ghc-lib-test-mini-hlint demo for an example.

```Haskell
import GHC.Lib.Parser

main :: IO ()
main = do
  let code = "main = putStrLn \"Hello\""
  case parseHaskell code of
    Left err -> putStrLn $ "Parse error: " ++ show err
    Right ast -> print ast
```

### Build ghc-lib with a specific GHC flavor

Source: https://github.com/digital-asset/ghc-lib/blob/master/README.md

Use this command to build the ghc-lib and ghc-lib-parser packages. Ensure you have cloned the repository and have the necessary GHC version available. This command uses a build tool to manage the process.

```bash
git clone git@github.com:digital-asset/ghc-lib.git
cd ghc-lib
cabal run exe:ghc-lib-build-tool -- --ghc-flavor=ghc-8.8.1
```

--------------------------------

### Build ghc-lib for DAML

Source: https://github.com/digital-asset/ghc-lib/blob/master/README.md

Use this command to build a DAML-specific version of ghc-lib. It requires enabling flags and specifying patch details for GHC.

```bash
cabal run exe:ghc-lib-build-tool -- \
  --da \
  --merge-base-sha=ghc-8.8.1-release \
  --patch=upstream/da-master-8.8.1 \
  --patch=upstream/da-unit-ids-8.8.1 \
  --gen-flavor=da-ghc-8.8.1 \
     --upstream=https://github.com/digital-asset/ghc.git
```

### Compile Haskell Code to GHC Core with ghc-lib

Source: https://github.com/digital-asset/ghc-lib/blob/master/README.md

Compile Haskell code up to GHC's Core language, including renaming and type checking, using ghc-lib. See the ghc-lib-test-mini-compile demo for usage.

```Haskell
import GHC.Lib.Compile

main :: IO ()
main = do
  let code = "foo :: Int
foo = 42"
  case compileHaskell code of
    Left err -> putStrLn $ "Compile error: " ++ show err
    Right core -> putStrLn core
```
