Readme for plugins-1.5.1.4

[back to package description]
------------------------------------------------------------------------
                            hs-plugins
------------------------------------------------------------------------

Compiler and tool support for compiling and loading, and evaluating
Haskell at runtime. 

The library provides a convenient interface to GHC's runtime loader
and linker, letting you load compiled Haskell code. 

It also provides a `make' system for compiling plugin source
automagically and for combining the user's .hs file with a stub of
standard declarations and syntax, saving the user from having to write
standard code themselves.

It provides an `eval' function, for generating new, well-typed, compiled
code from a Haskell source string.

It also provides a new variation of printf for Haskell-- a runtime
generated, dynamically-typed printf.

Read the documentation in doc/ for more.

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

BUILDING:
        $ chmod +x Setup.lhs configure
        $ ./Setup.lhs configure --prefix=/usr/local
        $ ./Setup.lhs build
        $ ./Setup.lhs install

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

DEPENDENCIES:

* Requires GHC >= 6.4
* Requires Cabal

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

* Optional:
   If you are doing a lot of `merge'-related operations, and require
   an extended haskell parser, you can compile hs-plugins to use 
   HSX, Niklas Broberg's Haskell parser library, available at:

    darcs get http://www.cs.chalmers.se/~d00nibro/haskell-src-exts

   To get hs-plugins to use HSX, use: 

        $ mv plugins.cabal.hsx plugins.cabal
        $ ./Setup.lhs configure --enable-hsx

   Make sure to install HSX first though :)

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

* On cygwin/windows you (a) make sure the cygwin "find" is before the
  windows "find" on your PATH, and (b) to give the windows-style path
  (e.g., "c:/cygwin/usr/local") in the ./configure --prefix=foo/bar
  step

* 'plugs' requires a working readline library.

* If you wish to use TH in plugins, or to run load()-programs in GHCi,
  you require a patch to GHC's linker, that was committed into ghc
  6.3, and ghc 6.2 -stable branch, and is available from 6.2.2 onwards.

* If you need to regenerate ./configure you need >= autoreconf-2.53

* The documentation relies on haddock, latex, dvips, tex2page:

        $ cd doc && make

EXAMPLES:

Have a look in the testsuite/ directory for many examples of how to
arrange your code.

LICENSE:

This library is distributed under the terms of the LGPL. The runtime
loader code is based on code written by Andr�Pang, and others, and is
distributed under the BSD-style Glasgow University license.

PORTABILITY:

Requires GHC 6.4 or greater, though most testing has be done on 6.4.
The dynamic loader requires a functional GHCi implementation.
