ChristmasTree: Changing Haskell's Read Implementation Such That by Mainpulating Abstract Syntax Trees it Reads Expressions Efficiently

[ library, parsing ] [ Propose Tags ]

Alternative approach of read that composes grammars instead of parsers. It reads data in linear time, while the function read has an exponential behavior in some cases of data types with infix operators.

Please check the right section in this file for instructions depending on how you obtained the source files.


Installing ChristmasTree from a source distribution
-------------------------------------------

  The source distribution can be unpacked from the
  .tar.gz files distributed in the following page:

    http://www.cs.uu.nl/wiki/bin/view/Center/TTTAS

  System wide installation (assumming GHC is the
  Haskell compiler) can be done like this:

    ghc --make Setup.hs -o setup -package Cabal
    ./setup configure
    ./setup build
    ./setup install


Installing uulib to a non-standard location
-------------------------------------------

  This is useful if you don't want (or can't)
  modify system wide settings.

    ghc --make Setup.hs -o setup -package Cabal
    ./setup configure --prefix=/foo
    ./setup build
    ./setup install --user

  The last command registers the package only for
  the user.



Optionally generating Haddock Documentation
