This is a plugin for the UUAG system. To use UUAG in combination with Cabal, add a dependency on the packages: uuagc -- installs the tool: uuagc uuagc-cabal -- installs a cabal plugin that uses uuagc Note that this package does not have a dependency on uuagc. You can use this module without having uuagc installed. (whether this is useful is a different question) Then write a custom Setup.hs: -- module Main where import Distribution.Simple import Distribution.Simple.UUAGC (uuagcLibUserHook) import UU.UUAGC (uuagc) main = defaultMainWithHooks (uuagcLibUserHook uuagc) -- Add extra-source-files: uuagc_options The contents of this file are options per AG module, as specified as follows. Write for each AG file: * Two lines in a file uuagc_options in the root of the package: -- file: "src-ag/Desugar.ag" options: module, pretty, catas, semfuns, signatures, genlinepragmas -- The options depend on what you actually want to compile. * Add an extra source file to the AG file in the cabal file: extra-source-files: src/MyProgram.ag * Add the module to the modules list in the cabal file.
