It allows you to write Haskell code (which may-be spread over multiple modules), and have an application (implemented in-any language with a Haskell FFI binding, including Haskell) load and use-your code at runtime.--\hsplugins{} provides 3 major features:-%-\begin{itemize}-        \item a dynamic loader,-        \item a compilation manager, and-        \item a Haskell evaluator-\end{itemize}--The \emph{dynamic loader} loads objects into the address space of an-application, along with any dependencies the plugin may have. The-loader is a binding to the GHC runtime system's dynamic linker, which-does single object loading. GHC also performs the necessary linking of-new objects into the running process. On top of the GHC loader is a-Haskell layer that arranges for module and package dependencies to be-found prior to loading individual modules.--The \emph{compilation manager} is a \code{make}-like system for-compiling Haskell source code into a form suitable for loading.  While-plugins are normally thought of as strictly object code, there are a-variety of scenarios where it is desirable to be able to inspect the-source code of a plugin, or to be able to recompile a plugin at runtime.-The compilation manager fills this role. It is particularly useful in-the implementation of \code{eval}.--The \emph{evaluator}, \code{eval}, utilizes the loader and compilation-manager. When passed a string containing a Haskell expression, it-compiles the string to object code, loads the result, and returns a-Haskell value representing the compiled string to the caller. It can be-considered a Haskell interpreter, implemented as a library, and can be-used to embed Haskell evaluation facilities in an application.--\section{Dynamic Loader}--The interface to the \hsplugins{} library can be divided into a number-of sections representing the functional units of the library.-Additionally, depending on the level of trust the application places-in the plugins, a variety of additional checks can be made on the-plugin as it is loaded. The levels of type safety possible are-summarised at the end of Section \ref{sec:compilation-manger} section.-The dynamic loader is available by using \code{-package plugins}.--\subsection*{Interface}-%-\begin{quote}-\scm{-import System.Plugins--load :: FilePath -     -> [FilePath] -     -> [PackageConf] -     -> Symbol -     -> IO (LoadStatus a)-}--\scm{-load_ :: FilePath -      -> [FilePath] -      -> Symbol -      -> IO (LoadStatus a)-}--\scm{-data LoadStatus a-    = LoadSuccess Module a -    | LoadFailure Errors-}-\end{quote}-%-Example:-%-\begin{quote}-\scm{-do mv <- load "Plugin.o" ["api"] [] "resource"-   case mv of-	LoadFailure msg -> print msg-	LoadSuccess _ v -> return v-}-\end{quote}-%-This is the basic interface to the dynamic loader. Load the object file-specified by the first argument into the address space (the library will-preload any module or package dependencies). The second argument is an-include path to any additional objects to load (possibly the API of the-plugin). The third argument is a list of paths to any user-defined-\code{package.conf} files, specifying packages unknown to the GHC-package system. \code{Symbol} is a string specifying the symbol name you-wish to lookup. \code{load} returns a \code{LoadStatus} value representing-failure, or an abstract representation of the module (for calls to-\code{unload} or \code{reload}) with the symbol as a Haskell value. The-value returned must be given an explicit type signature, or provided-with appropriate type constraints such that GHC can determine the-expected type returned by \code{load}.--\code{load\_} is provided for the common situation where no user-defined-package.conf files are required.--\begin{quote}-\scm{-dynload :: Typeable a    -        => FilePath  -        -> [FilePath]-        -> [PackageConf]-        -> Symbol-        -> IO (LoadStatus a)-}-\end{quote}-%-Example:-%-\begin{quote}-\scm{-do mv <- dynload "Plugin.o" ["api"] ["plugins.conf.inplace"] "resource"-   case mv of-	LoadFailure msg -> print msg-	LoadSuccess _ v -> putStrLn v-}-\end{quote}-%-\code{dynload} is a safer form of \code{load}. It uses dynamic types-to perform a check on the value returned by \code{load} at runtime, to-ensure that it has the type the application expects it to have.--In order to use \code{dynload}, the symbol the plugin exports must be-of type \code{AltData.Dynamic:Dynamic}. (See the \code{AltData} library-distributed with \hsplugins{}, and the \hsplugins{}-\code{examples/dynload} directory. References to \code{Typeable} and-\code{Dynamic} refer to the \hsplugins{} reimplementation of these-libraries. \code{AltData.Dynamic} is used at the moment, as there is a-limitation in the existing Data.Dynamic library in the presence of-dynamic loading).--The value wrapped up in the \code{Dynamic} must be an instance of-\code{AltData.Typeable}. If the value exported by the plugin \emph{is}-of type \code{Dynamic}, and the value wrapped by the \code{Dynamic}-does not match the type expected of it by the application,-\code{dynload} will return \code{Nothing}, indicating that the plugin-is not typesafe with respect to the application. If the value passes-the typecheck, \code{dynload} will return \code{LoadSuccess}. If the value-exported by the plugin is \emph{not} of type \code{Dynamic},-\code{dynload} will crash---this is a limitation of the existing-\code{Dynamic} library, it can only type-check \code{Dynamic} values.-Additionally, Data.Dynamic is limited to monomorphic types, or must be-wrapped inside a rank-N type to hide the polymorphism from the-typechecker. This is a bit cumbersome. An alternative typesafe-\code{load} is available via the \code{pdynload} interface, which is-able to enforce the type of the plugin using GHC's type inference-mechanism, and is not restricted in its expressiveness (at the cost of-greater load times):--\begin{quote}-\scm{-pdynload :: FilePath-         -> [FilePath]-         -> [PackageConf]-         -> Type-         -> Symbol-         -> IO (LoadStatus a)-}--\scm{-pdynload_ :: FilePath-          -> [FilePath]-          -> [PackageConf]-          -> [Arg]-          -> Type-          -> Symbol-          -> IO (LoadStatus a)-}-\end{quote}-%-Example:-%-\begin{quote}-\scm{-do v <- pdynload "Plugin.o" ["api"] [] "API.Interface" "resource"-   case v of-	LoadSuccess _ a  -> putStrLn "yay!"-	_                -> putStrLn "type error"-}-\end{quote}-%-\code{pdynload} is a replacement for \code{dynload}, which provides a-solution to the various problems caused by the existing dynamics-library in Haskell. Rather than use normal dynamics, which constrain-us to monomorphic types only (or rank-N types), it instead uses GHC's-type inference to unify the plugin's export value with that provided-by the api (via its .hi file).  It is a form of \emph{staged type inference}-for module interfaces, allowing plugins to use any type definable in Haskell.-\code{pdynload} is like \code{dynload}, but requires a new \code{Type}-argument. This can be considered a type annotation on the value the plugin-should be constrained to.--Prior to loading the object, \code{pdynload} generates a tiny Haskell-source file containing, for example:-%-\begin{quote}-\scm{-module APITypeConstraint where-import qualified API-import qualified Plugin--_ = Plugin.resource :: API.Interface-}-\end{quote}-%-It then calls GHC's type checker on this file, which runs the full-Haskell type inference machinery. If the file typecheckes, then the-plugin type is correct, and the plugin is safe to load, otherwise it-is an error. --Because we use the full Haskell type checker, we can have a form of-dynamic typechecking, on any type expressable in Haskell. A plugin's-value may, for example, have class constraints -- something not-checkable using the standard Dyanmic type. The cost is that-\code{pdynload} is roughly 46\% slower than an unchecked load.- -The type of the plugin's resource field must be equivalent to the-\code{Type}. There are some restrictions on the arguments that may be-passed to pdynload. Currently, we require:-        \begin{itemize}-        \item The object name has the suffix (.o) removed and this-        becomes a qualified module name in the generated type-checker-        input file.--        \item The type name must be a single fully-qualified-        type-identifier, as the module name is stripped off (i.e.-        everything up to the last ".") and used as a qualified import.-        This means that you can't use, for example, \code{"Int ->-        String"} as a type (type synonyms are fine, though).--\end{itemize}--For example, \code{pdynload "API2.o" ["./"] [] "API.PluginAPI"-"doAction"} generates:--\begin{quote}-\scm{-module <temp-generated-name> where-import qualified API    -- comes from API.PluginAPI argument-import qualified API2   -- comes from API2.o argument-_ = API2.doAction :: API.PluginAPI-}-\end{quote}--\begin{quote}-\scm{-unload :: Module -> IO ()-}--\scm{-unloadAll :: Module -> IO ()-}-\end{quote}--Unload an object, \emph{but not its dependencies} from the address-space. \code{unloadAll} performs cascading unloading of a module-\emph{and} its dependencies.--\begin{quote}-\scm{-reload :: Module -> Symbol -> IO (LoadStatus a)-}-\end{quote}--Unload, and then reload a module that must have been previously-loaded.

This can be mitigated somewhat via-the use of \code{make} to ensure that the plugin is at least Haskell-code that is well-typed internally (if we trust GHC to compile it-correctly). --If we trust the user to provide an interface of \code{Dynamic} type, we-can check the plugin type at runtime, but the plugin's value must be-\code{Typeable}, which restricts it to be a monomorphic type (or to-using rank-N tricks). --The greatest safety can be obtained by using \code{pdynload}, at the-cost of increased load times. \code{pdynload} essentially performs full-type inference on the plugin interface at runtime. The type safety of-the plugin, using \code{pdynload}, is then as safe as if the plugin was-statically compiled into the application. It does not provide any-\emph{further} safety than exists in static compilation. For example, it-does not preclude the use of (evil) \code{unsafeCoerce\#} to defeat-type-checking, either statically or at runtime. An extensive discussion-of type safe plugin loading is available in the \hsplugins{} paper-\urlh{http://www.cse.unsw.edu.au/~dons/hs-plugins/paper}{here}.--\newpage--\section{Eval.Haskell}--\code{eval}, and its siblings, provide a mechanism to compile and run-Haskell code at runtime, in the form of a String. The general framework-is that the string is used to create a plugin source file, which is-compiled and loaded, and type checked against its use. The resulting-value is returned to the caller. It resembles a runtime metaprogramming-\code{run} operator for closed code fragments.--\subsection*{Interface}--\begin{quote}-\scm{-import System.Eval.Haskell--eval :: Typeable a => String -> [Import] -> IO (Maybe a)--eval_ :: Typeable a =>-         String      -- code to compile-      -> [Import]    -- any imports-      -> [String]    -- extra ghc flags-      -> [FilePath]  -- extra package.conf files-      -> [FilePath]  -- include search paths-      -> IO (Either [String] (Maybe a))-}-\end{quote}--\code{eval} takes a string, and a list of import module names, and-returns a \code{Maybe} value. \code{Nothing} means the code did not-compile, or did not typecheck at its splice point. \code{Just v} gives-you \code{v}, the result of evaluating your code. It is interesting to-note that \code{eval} has the type of an interpreter. The-\code{Typeable} constraint is used to type check the evaluated code when-it is loaded, using \code{dynload}.  As usual, \code{eval\_} is a-version of \code{eval} that lets you pass extra flags to ghc and to the-dynamic loader.--The existing \code{Data.Dynamic} library requires that only monomorphic-values are \code{Typeable}, so in order to evaluate polymorphic-functions you need to wrap them up using rank-N types.

However, its lets us remove some-restrictions on what types can be evaluated, which can be useful.--{unsafeEval\_} lets the application have full control over the import-environment and load flags to the eval call, which is useful for-applications that wish to script themselves, and require specific-modules and packages to be in scope in the eval-generated module.--This example maps a \code{toUpper} over a list:-%-\begin{quote}-\scm{-import Eval.Haskell--main = do s <- unsafeEval "map toUpper \"haskell\"" ["Data.Char"]-          when (isJust s) $ putStrLn (fromJust s)-}-\end{quote}- -And here we evaluate a lambda abstraction, applying the result to-construct a tuple.

Therefore,-\hsplugins{} only works on platforms with a working GHCi. This library-is based on code from André Pang's runtime loader. The low level-interface is as follows:--\begin{itemize}-      \item \code{initLinker}  \em  start the linker up -      \item \code{loadObject}  \em  load a vanilla .o-      \item \code{loadPackage} \em  load a GHC library and its cbits-      \item \code{loadShared } \em  load a .so object file-      \item \code{resolveObjs} \em  and resolve symbols-\end{itemize}--Additionally, \code{Hi.Parser} provides an interface to a GHC-\code{.hi} file parser. Currently we only parse just the dependency-information, import and export information from \code{.hi} files, but-all the code is there for an application to extract other information-from \code{.hi} files.--\newpage--\section{Dynamic Loader Implementation}--The dynamic loader is the system by which modules, and their-dependencies can be loaded, unloaded or reloaded at runtime, and-through which we access the functions we need.--At its lowest level, the \hsplugins{} loader is a binding to the GHC-runtime loader and linker. This layer is a direct reimplementation of-Andre Pang's \code{runtime\_loader} (barely any code changed). The-code at this level can only load single modules, or packages/archives-(which are just objects too). Any dependency resolution must be-performed by hand.--On top of Andre's interface is a more convenient interface through-which user's should interact with the dynamic loader.  The most-significant extension to Andre's work is the automatic calculation and-loading of a plugin's package or module dependencies via .hi file-information.  It also handles initialisation of the loader, and-retrieval of values from the plugin in a more convenient way. Some-state is also stored in the loader to keep track of which modules and-packages have been loaded, to prevent unnecessary (actually, fatal)-loading of object files and packages already loaded.  Thus you can-safely load several plugins at once, that share common dependencies,-without worrying about the dependencies being loaded multiple times.-We also store package.conf information in the state, so we can work-out where a package lives and what it depends on.--The ability to remember which packages and objects have been loaded is-based on ideas in Hampus Ram's dynamic loader, which has a more-advanced dependency tracking system, with the ability to unload the-dependencies of a plugin. \hsplugins{} doesn't provide ``cascading-unloading''. The advantage \hsplugins{} has over Hampus' loader seems-to be the automatic dependency resolution via vanilla .hi files and-the dynamic recompilation stuff.--Using \code{load}, any library packages, or any \code{.o} files, that a-plugin depends upon will be automatically loaded prior to loading the-module itself. \code{load} then looks up a symbol from the object file,-and returns the value associated with the symbol as a conventional-Haskell value. It should also be possible to load a GHCi-style \code{.o}-archive of object files this way, although there is currently no way-to extract multple plugin interfaces from a archive of objects.--The application writer is not required to recalculate dependencies if-the plugin changes, and the plugin author does not need to specify-what dependencies exist, as is required in the lower level interface.-This is achieved by using the dependency information calculated by GHC-itself, stored in .hi files, to work out which modules and packages to-load, and in what order. A plugin in \hsplugins{} is really a pair of-an object file (or archive) and a \code{.hi} file, containing package-and module dependency information.  --The \code{.hi} file is created by GHC when the plugin is compiled,-either by hand or via \code{make}.  \code{load} uses a binary parser to-extract the relevant information from the \code{.hi} data. Because the-dependency information is stored in a separate file to the application-that loads the plugin, such information can be recalculated without-having to modify the application. Becaues of this, it was easy to-extend the load to support recompilation of module source, even if-dependencies change, because dependencies are no longer hard-coded-into the application source itself, but are specified by the plugin.--Assuming we have a plugin exporting some data, ``resource'', with a-record name \code{field :: String}, here is an example call to \code{load}:-%-\begin{quote}-\scm{-do m_v   <- load "Test.o" ["."] [] "resource"-   v <- case m_v of-          LoadSuccess _ v -> return v-          _               -> error "load failed"-   putStrLn $ field v-}-\end{quote}--This loads the object file \code{Test.o}, and any packages or objects-\code{Test.o} depends on. It resolves undefined symbols, and returns-from the object file the Haskell value named ``resource'', as the-value ``v''. This must be a value exported by the plugin. We then-retrieve the \code{field} component of \code{v}, and print it out.--This simple usage assumes that the plugin to load is in the same-directory as the application, and that the api defining the interface-between plugin and application is also in the current directory (hence-the ``.'' in the 2nd argument to \code{load}).--\subsection*{Dynamically Loading the Dynamic Loader}--It is also possible to load the \code{plugins} or \code{eval}-libraries in GHC. Here, for example, we load the \code{plugs}-interactive environment in GHCi, and evaluated some code. The source to-\code{plugs} is in Appendix-\ref{sec:plugs}.-%-\begin{quote}-\begin{verbatim}-paprika$ ghci -package-conf ../../../plugins.conf.inplace -package eval-   ___         ___ _-  / _ \ /\  /\/ __(_)- / /_\// /_/ / /  | |      GHC Interactive, version 6.3, for Haskell 98.-/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/-\____/\/ /_/\____/|_|      Type :? for help.--Loading package base ... linking ... done.-Loading package altdata ... linking ... done.-Loading package unix ... linking ... done.-Loading package mtl ... linking ... done.-Loading package lang ... linking ... done.-Loading package posix ... linking ... done.-Loading package haskell98 ... linking ... done.-Loading package haskell-src ... linking ... done.-Loading package plugins ... linking ... done.-Loading package eval ... linking ... done.-Prelude> :l Main-Skipping  Main             ( Main.hs, Main.o )-Ok, modules loaded: Main.-Prelude Main> main-Loading package readline ... linking ... done.-           __                          -    ____  / /_  ______ ______          -   / __ \/ / / / / __ `/ ___/     PLugin User's GHCi System, for Haskell 98-  / /_/ / / /_/ / /_/ (__  )      http://www.cse.unsw.edu.au/~dons/hs-plugins- / .___/_/\__,_/\__, /____/       Type :? for help     -/_/            /____/                  --Loading package base ... linking ... done-plugs> map (\x -> x + 1) [0..10]-[1,2,3,4,5,6,7,8,9,10,11]-plugs> :t "haskell"-"haskell" :: [Char]-plugs> :q-*** Exception: exit: ExitSuccess-Prelude Main> :q-Leaving GHCi.-\end{verbatim}-\end{quote}--\subsection*{Dynamic Typing}--Support is also provided to unwrap and check the type of dynamically-typed plugin values (those wrapper in a \code{toDyn}) via-\code{dynload}. This is the same as \code{load}, except that instead-of a returning the value it finds, it unwraps a dynamically typed-value, checks the type, and returns the unwrapped value. This is to-provide further trust that the symbol you are retrieving from the-plugin is of the type you think it is, beyond that trust you have by-knowing that the plugin was compiled against a shared API. By using-\code{dynload} it is not enough for an object file to just have the-same symbol name as the function you require, it must also carry the-\code{Data.Dynamic} representation of the type, too. \code{pdynload}-rectifies most of \code{dynload}'s limitations, but at the cost of-additional running time.--\section{Compilation Manager Implementation}--Along side the dynamic loader is the compilation manager.  This is a-\code{make}-like system for compiling Haskell source, prior to loading-it. \code{make} checks if a source file is newer than its associated-object file. If so, the source is recompiled to an object file, and a-new dependency file is created, in case the dependencies have changed-in the source. This module can then be loaded.  The idea is to allow-EDSL authors to write plugins without having to touch a compiler: it-is all transparent. It also allows us to enforce type safety in the-plugin by injecting type constraints into the plugin source, as has-been discussed eariler.--The effect is much like \emph{hi} (Hmake Interactive), funnily enough.-An application using both \code{make} and \code{load} behaves like a-Haskell interpreter, using \code{eval}.  You modify your plugin, and-the application notices the change, recompiles it (possibly issuing-type errors) and then reloads the object file, providing the-application with the latest version of the code.- -An example:-%-\begin{quote}-\scm{-do status <- make "Plugin.hs" []-   obj    <- case status of-                MakeSuccess _ o -> return o-                MakeFailure e   -> mapM_ putStrLn e >> error "failed"--   m_v    <- load obj ["api"] [] "resource"-   v      <- case m_v of-            	LoadSuccess _ v -> return v-            	_               -> error "load failed"-   putStrLn $ field v-}-\end{quote}--\code{make} accepts a source file as an argument, and a (usually empty)-list of GHC flags needed to compile the object file. It then checks to-see if compilation is required, and if so, it calls GHC to compile the-code, with and arguments supplied. If any errors were generated by-GHC, they are returned as the third component of the triple.--Usually it will be necessary to ensure that GHC can find the plugin-API to compile against. This can be done by either making sure the API-is in the same directory as the plugin, or by adding a \code{-i} flag to-\code{make}'s arguments. If the API is created as a ``package'' with a-package.conf file, \code{make} can be given \code{-package-conf} arguments-to the same effect.--Normally, \code{make} generates the \code{.o} and \code{.hi} files in-the same directory as the source file. This is not always desirable,-particularly for interpreter-like applications. To solve this, you can-pass \code{[''-odir'', path]} as elements of the arg list to-\code{make}, and it will respect these arguments, generating the-object and interface file in the directory specified. GHC's argument-\code{''-o''} is also respected in a similar manner, so you could also-say \code{[''-o'', obj]} for the same effect.--\code{make} is entirely optional. All user's have to do to use the-loader on its own is make sure they only load object files that also-have a \code{.hi} file. This will usually be the case if the plugin is-compiled with GHC.--\subsection*{makeWith}--\code{makeWith} merges two source files together, using the function-and value declarations from one file, with any syntax in the second,-creating a new third source file. It then compiles this source file-via \code{make}.--This function exists as a benefit to EDSL authors and is related to-the original motivation for \hsplugins{}, as a .conf file language-library. Configuration files need to be clean and simple, and you-can't rely, or trust, the user to get all the compulsory details-correct. So the solution is to factor out any compulsory syntax, such-as module names, imports, and also to provide a default instance of-the API, and store this code in a separate file provided by the-application writer, not the user.  \code{makeWith} then merges-whatever the user has written, with the syntax stub, generating a-complete Haskell plugin source, with the correct module names and-import declarations. We also ensure the plugin only exports a single-interface value while we are here.--\code{makeWith} thus requires a Haskell parser to parse two source files-and merge the results. We are merging abstract syntax here. This is-implemented using the Language.Haskell parser library. Unfortunately,-this library doesn't implement all of GHC's extensions, so if you wish-to use \code{makeWith} you can only write Haskell source that can be-parsed by this library, which is just H98 and a few extensions. This-is another short coming in the current design that will be overcome-with \code{-package ghc}. Remember, however, for normal uses of-\code{make} and \code{load} you are unrestricted in what Haskell you use.-This is the same restriction present in happy, the Haskell parser,-placed on the code you can provide in the \code{.y} source.--\code{makeWith} also makes use of line pragmas. If the merged file-fails to compile, the judicious use of line number pragmas ensure that-the user receives errors messages reported with reference to their-source file, and not line number in the merged file. This is a-property of the Language.Haskell parser that we can make use of.--An example of \code{makeWith}:-%-\begin{quote}-\scm{-do status <- makeWith "Plugin.in" "Plugin.stub" []-   obj <- case status of-                MakeFailure e   -> mapM_ putStrLn e >> error "failed"-                MakeSuccess _ o -> return o-   m_v  <- load obj [apipath] [] "resource"-   v <- case m_v of-                LoadSuccess _ v -> return v-                _               -> error "load failed"-   putStrLn $ field v-}-\end{quote}--We combine the user's file (\code{Plugin.in}) with a stub of syntax-generating a new, third Haskell file in the default tmpdir. This is-compiled as per usual, producing object and interface files. The-object is then loaded, and we extract the value exported.--Using \code{makeWith} it is possible to write very simple, clear-Haskell plugins, that appear not to be Haskell at all. It is an easy-way to get EDSL user's writing plugins that are actually Haskell-programs, for .e.g, configuration files. See the examples that come-with the src.--\newpage--\section{An Example}--This is an introductory example.--\subsection*{API}--First we need an interface between the application and the plugin.-This module needs to be visible to both the app and the plugin, in the-interest of clear and well-defined interfaces: -%-\begin{quote}-\scm{-module StringProcAPI (Interface(..), plugin) where--data Interface = Interface {-       stringProcessor :: String -> String-}--plugin :: Interface-plugin = Interface { stringProcessor = id }-}-\end{quote}--Here we define \code{Interface} as the inteface signature for the-object passed between plugin and application. We'll use the record-syntax as it looks intuitive in the plugin. We provide a default-instance, the \code{plugin} value, that can be overwritten in the-actual plugin, ensuring sensible behaviour in the absence of any-plugins. The API should theoretically be compiled with \code{-Onot} to-avoid interface details leaking out into the \code{.hi} file.--\subsection*{The Plugin}--This is our plugin. Note that the plugin will be compiled entirely-seperately from the application. It must only rely on the API, and-nothing in the application source.-%-\begin{quote}-\scm{-module StringProcPlugin (resource) where--import StringProcAPI (plugin)--resource = plugin {-     stringProcessor = reverse -}-}-\end{quote}--Using the record syntax we overwrite the \code{function} field with our-own value, \code{reverse}. The value \code{resource} is the magic symbol-that must be defined, and which the application will use to find the-data the plugin exports.--Now, we can make this even easier on the plugin writer by the use of a-``stub'' file. \code{makeWith} lets you merge a plugin source with-another Haskell file, and compiles the result into the actual plugin-object. So the application can provide a stub file containing module-declarations and imports, and a default plugin value. Here is an-application-provided stub, factoring out compulsory syntax and type-declarations from the plugin:-%-\begin{quote}-\scm{-module StringProcPlugin ( resource ) where--import StringProcAPI--resource :: Interface-resource = plugin-}-\end{quote}--By factoring out compulsory syntax, the plugin author only has to-provide an overriding instance of the \code{resource} field. So all-the plugin actually consists of, is:-%-\begin{quote}-\scm{-resource = plugin {-      stringProcessor = reverse-}-}-\end{quote}--That is all the code we need! This file may be called anything at all.--More complex APIs may have more fields, of course. The nice thing-about this arrangement is that the user will write some simple syntax,-which will nonetheless by typechecked safely against the API. Errors-are also reported using line numbers from the source file, not the-stub, which makes things less confusing.--\subsection*{The Application}--Now we need to write an application that can use values of the kind-defined in the API, and which can compile and load plugins. The basic-mechanism to compile and load a plugin is as follows:-%-\begin{quote}-\scm{-do status <- make "StringProcPlugin.hs" []-   obj    <- case status of-                MakeSuccess _ o -> return o-                MakeFailure e   -> mapM_ putStrLn e >> error "failed"--   m_v    <- load obj ["."] [] "resource"-   val    <- case m_v of-                LoadSuccess _ v -> return v-                _               -> error "load failed"-}-\end{quote}-%-This code calls \code{make} to compile the plugin source, yielding-wrapper around a handle to an object file. The object can then be loaded-using \code{load}, and the code associated with the symbol-\code{resource} is retrieved. --We embed this code in a simple shell-like loop, applying the function-exported by the plugin:-%-\begin{quote}-\scm{-import System.Plugins-import StringProcessorAPI-import System.Console.Readline-import System.Exit--source = "Plugin.hs"-stub   = "Plugin.stub"-symbol = "resource"--main = do s <- makeWith source stub []-          o <- case s of-                MakeSuccess _ obj -> do-                        ls <- load obj ["."] [] symbol-                        case ls of LoadSuccess m v -> return (m,v)-                                   LoadFailure err -> error "load failed"-                MakeFailure e -> mapM_ putStrLn e >> error "compile failed"-          shell o--shell o@(m,plugin) = do -        s <- readline "> "-        cmd <- case s of -                Nothing          -> exitWith ExitSuccess-                Just (':':'q':_) -> exitWith ExitSuccess-                Just s           -> addHistory s >> return s--        s  <- makeWith source stub []   -- maybe recompile the source-        o' <- case s of-                MakeSuccess ReComp o -> do -                        ls <- reload m symbol-                        case ls of LoadSuccess m' v' -> return (m',v')-                                   LoadFailure err   -> error "reload failed"-                MakeSuccess NotReq _ -> return o-                MakeFailure e -> mapM_ putStrLn e >> shell o-        eval cmd o'-        shell o'--eval ":?" _ = putStrLn ":?\n:q\n<string>"--eval s (_,plugin) = let fn = (stringProcessor plugin) in putStrLn (fn s)-}-\end{quote}--We have to import the hs-plugins library, and the API. The main loop-proceeds by compiling and loading the plugin for the first time, and-then calls \code{shell}, the interpeter loop. This loop lets us apply-the function in the plugin to strings we supply.  We have to pass-around the \code{(Module, a)} pair we get back from \code{reload}, so-that we can pass it to \code{eval} to do the real work.  The first-\code{eval} case is where we use the record syntax to select the-\code{function} field out of \code{v}, the plugin interface object,-and we apply it to s. Try it out:-%-\begin{quote}-\begin{verbatim}-paprika$ ./a.out -Loading package base ... linking ... done-Loading objects API Plugin ... done-> :?-":?"-":q"-"<string>"-> abcdefg-gfedcba-\end{verbatim}-\end{quote}--Now, if we edit the plugin while the shell is running, the next time-we type something at the prompt the plugin will be unloaded,-recompiled and reloaded. Because the plugin is really an EDSL, we can-use any Haskell we want, so we'll change the plugin to:-%-\begin{quote}-\scm{-import Data.Char--resource = plugin {-	stringProcessor = my_fn-}--my_fn s = map toUpper (reverse s)-}-\end{quote}--Back to the shell:-%-\begin{quote}-\begin{verbatim}-> abcdefg -Compiling plugin ... done-Reloading Plugin ... done-GFEDCBA-\end{verbatim}-\end{quote}--And that's it: dynamically recompiled and reload Haskell code!--\section{Multiple Plugins}--It is quite easy to load multiple plugins, that all implement the-common plugin API, and that all export the same value (though-implemented differently). This make \hsplugins{} suitable for-applications that wish to allow an arbitrary number of plugins. The-main problem with multiple plugins is that they may share-dependencies, and if \code{load} na\"ively loaded all dependencies-found in the set of \code{.hi} files associated with all the plugins,-the GHC rts would crash. To solve this the \hsplugins{} dynamic loader-maintains state storing a list of what modules and packages have been-loaded already. If \code{load} is called on a module that is already-loaded, or dependencies are attempted to load, that have already been-loaded, the dynamic loader ignores these extra dependencies. This-makes it quite easy to write an application that will allows an-arbitrary number of plugins to be loaded. An example follows.--\subsection*{Definition}--First we need to define the API that a plugin must type check against,-in order to be valid.  -%-\begin{quote}-\scm{-module API where--data Interface = Interface { -	valueOf :: String -> String -}--plugin :: Interface -plugin = Interface { valueOf = id }-}-\end{quote}--We can then implement a number of plugins that provide values of type-"Interface". We show three plugins that export string manipulation functions:-%-\begin{quote}-\scm{-module Plugin1 where--import API-import Data.Char--resource = plugin {-	valueOf = \s -> map toUpper s-}-}-\end{quote}--\begin{quote}-\scm{-module Plugin2 where--import API-import Data.Char--resource = plugin {-	valueOf = \s -> map toLower s-}-}-\end{quote}--\begin{quote}-\scm{-module Plugin3 where--import API--resource = plugin {-	valueOf = reverse-}-}-\end{quote}--And finally we need to write an application that would use these-plugins. Remember that the application is written without knowledge of-the plugins, and the plugins are written without knowledge of the-application. They are each implemented only in terms of the API, a-shared module and \code{.hi} file. An application needs to make the-API interface available to plugin authors, by distributing the API-object file and \code{.hi} file with the application.-%-\begin{quote}-\scm{-import System.Plugins-import API--main = do- let plist = ["Plugin1.o", "Plugin2.o", "Plugin3.o"]- plugins <- mapM (\p -> load p ["."] [] "resource") plist- let functions = map (valueOf . fromLoadSuc) plugins- mapM_ (\f -> putStrLn $ f "haskell is for hackers") functions--fromLoadSuc (LoadFailure _)   = error "load failed"-fromLoadSuc (LoadSuccess _ v) = v--}-\end{quote}--This application simply loads all the plugins and retrieves the-functions they export. It then applies each of these functions to a-string, printing the result. We assume for this example that the-plugins are compiled once only, and are not compiled dynamically via-\code{make}. This implies that you have to use \code{GHC} to generate-the \code{.hi} file for each plugin. A sample Makefile to compile the-plugins, and the api:-%-\begin{quote}-\begin{verbatim}-all:-    ghc -Onot -c API.hs-    ghc -O -c Plugin1.hs-    ghc -O -c Plugin2.hs-    ghc -O -c Plugin3.hs-\end{verbatim}-\end{quote}--Ghc creates \code{.hi} files for each plugin, which can be inspected-using the \code{Plugins.BinIface.readBinIface} function. It parses the-\code{.hi} file, generating, roughly, the following:-%-\begin{quote}-\begin{verbatim}-interface "Main" Main-module dependencies: A, B-package dependencies: base, haskell98, lang, unix-\end{verbatim}-\end{quote}--which says that the plugin depends upon a variety of system packages,-and the modules A and B. All these dependencies must be loaded before-the plugin itself.--You then need to compile the application against the API, and against-the \hsplugins{} library:-%-\begin{quote}-\begin{verbatim}-ghc -O --make -package plugins Main.hs-\end{verbatim}-\end{quote}--Running the application produces the following result. Note that the-verbose output can be switched off by compiling \hsplugins{} without-the \code{-DDEBUG} flag. If you look at the \code{.hi} file, using-\code{ghc --show-iface}, you'll see that they all depend on the base-package, and on the API, but the state stored in the dynamic loader-ensures that these shared modules are only loaded once:-%-\begin{quote}-\begin{verbatim}-Loading package base ... linking ... done-Loading object API Plugin1 ... done-Loading object Plugin2 ... done-Loading object Plugin3 ... done--HASKELL IS FOR HACKERS-haskell is for hackers-srekcah rof si lleksah-\end{verbatim}-\end{quote}--Archives of plugins can be loaded in one go if they have been linked-into a .o GHCi package, see \code{loadPackage}.--\newpage--\appendix--\section{License} --This library is distributed under the terms of the LGPL:--\begin{quote}--Copyright 2003-5, Don Stewart - \url{http://www.cse.unsw.edu.au/~dons}--This library is free software; you can redistribute it and/or-modify it under the terms of the GNU Lesser General Public-License as published by the Free Software Foundation; either-version 2.1 of the License, or (at your option) any later version.--This library is distributed in the hope that it will be useful,-but WITHOUT ANY WARRANTY; without even the implied warranty of-MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Rather than compiling the-user's code to an executable, we use \hsplugins{} to instead load an-object file and execute that instead, using the \code{eval} interface.-This cuts out the linking phase from the process, making turnaround at-the prompt around twice as fast as \code{hi}.--\subsection*{Source of Plugs}--\begin{quote}-\scm{-import System.Eval.Haskell-import System.Plugins--import System.Exit              ( ExitCode(..), exitWith )-import System.IO-import System.Console.Readline  ( readline, addHistory )--symbol = "resource"--main = do-        putStrLn banner -        putStr "Loading package base" >> hFlush stdout-        loadPackage "base" -        putStr " ... linking ...
