The indexer uses GHC API to create a data structure that contains detailed information about the source code of a Cabal package. The HTTP server reads that data structure into memory and responds to HTTP requests from the JavaScript application. + +## Motivation + +Reading and understanding code is an essential part of the software development process. Understanding code in any statically typed language is much easier when code intelligence features (types on hover, go-to-definition, etc.) are available. Code intelligence for Haskell is especially useful because types are informative and precise (thanks to Haskell's purity and global type inference). + +## Features + +* Types (actual type, instantiated type, instance resolution tree) and documentation on hover. Types are interactive : left-click on type constructor -> go to definition, right click on type constructor -> show kind signature.

The reason for this is that `haskell-code-indexer` uses `cabal-helper` library [https://hackage.haskell.org/package/cabal-helper](https://hackage.haskell.org/package/cabal-helper) to get package build information. `cabal-helper` builds (at runtime) an executable linked against a version of Cabal library that was used to configure the package. + +If there is no globally installed GHC on the system, then it is possible to use `stack exec` command ([https://docs.haskellstack.org/en/stable/GUIDE/#exec](https://docs.haskellstack.org/en/stable/GUIDE/#exec)) that adds a path to GHC binaries installed by Stack to `PATH` environment variable : + +```bash +stack --resolver=lts-11.3 exec haskell-code-indexer -- INDEXER_OPTIONS +``` + +### Examples : + +Show all indexer options: +```bash +haskell-code-indexer -h +``` + +Index package : +```bash +haskell-code-indexer --package PATH +``` + +Index package with specific dist directory : +```bash +haskell-code-indexer --package PATH --dist dist-newstyle +``` + +Index package built by Stack : +```bash +haskell-code-indexer --package PATH --dist $(stack path --dist-dir) +``` + +## Starting HTTP Server + +`haskell-code-server` executable reads the package index created by `haskell-code-indexer` and starts the HTTP server.
