This tool downloads sources of Stack project's dependencies to a .hs-src-tool folder and uses https://github.com/alexwl/haskell-code-explorer to index and browse them.

1. Make sure that stack, cabal, haskell-code-indexer, haskell-code-server, and of course hs-src-tool are on your $PATH
2. The tool is designed to be run from the root of Stack project:

   $ cd $PROJECT_ROOT

3. Make sure that your project uses the same version of GHC as haskell-code-indexer and haskell-code-server!
4. Build your project first:

   $ stack build

5. Now fetch the sources:

   $ hs-src-tool fetch

6. Sources shold be in $PROJECT_ROOT/.hs-src-tool folder
7. Index your project and its dependencies

   $ hs-src-tool index

8. Start the sources explorer

   $ hs-src-tool explore --port=8080 --ui=$PATH_TO_HASKELL_CODE_EXPLORER_REPO/javascript/release

9. Open http://localhost:8080 and enjoy!

Note that hs-src-tool tries its best to build and index as many packages as it can. Meaning that failing packages are skipped. If you don't see some specific package in the explorer - take a look on hs-src-tool index output.
