synopsis:            a library to work with tags created from Haskell parsed tree
description:
  === library scope
  .
  'ghc-tags-core' library provides:
  .
  * a function to extract /tag/ information from @'HsModule' 'GhcPs'@ parsed tree representation of Haskell code,
  * parsers for __ctag__ and __etag__ style tag files (/vim/ \/ /emacs/),
  * formatting tags into __ctag__ and __etag__ files,
  * tries to be compatible with [universal-ctags](https://github.com/universal-ctags/ctags).
  .
  === developer tools
  Check out these projects:
  .
  * [ghc-tags](https://hackage.haskell.org/package/ghc-tags) - a standalone ghc tags generator;
  * [ghc-tags-plugin](https://hackage.haskell.org/package/ghc-tags-plugin) -
    a ghc [compiler
    plugin](https://ghc.gitlab.haskell.org/ghc/doc/users_guide/extending_ghc.html?highlight=compiler%20plugin#compiler-plugins)
    which extracts tags during @GHC@'s parser pass and from TH splices.
