Let's play Name That Extension!
by Stefan O'Rear 31 Mar '07

31 Mar '07

A large number of the newer GHC extensions have no cabal name. This is a very bad situation because if Hugs/yhc/etc were to gain support for (say) GADTs, it would not be possible to run cabal programs that require them, since the way programs specify dependency is with -fglasgow-exts. Also, what is the protocol for requesting cabal extension names? I've many Cool Extension Ideas for my haskeell impl project (nowhere near done). Stefan

Cabal and RPM redux
by Bryan O'Sullivan 27 Mar '07

27 Mar '07

Since my last attempt to add RPM support didn't go anywhere, I'd like to figure out what's a good way to make progress. If I were to contribute a standalone program called cabal-rpm (just as cabal-install is a standalone program), would that be acceptable to add to the darcs repo? <b

Extensions and Cabal
by Ian Lynagh 24 Mar '07

24 Mar '07

Hi Cabalites, I fear this may be contentious, but here goes anyway... Currently we have (at least) 4 ways that extension E can be enabled for a given file in a cabal package (using GHC as an example, if -fe enables E): 1. foo.cabal: Extensions: E 2. foo.cabal: Ghc-Options: -fe 3. Foo.hs: {-# LANGUAGE E #-} 4. Foo.hs: {-# OPTIONS_GHC -fe #-} Ideally, from cabal's point of view, we would use option 1. This way cabal knows about the extensions, so can fail early if we don't support the necessary extensions to build something. 2 and 4 are inferior variants of 1 and 3 respectively; the only case I can think of where you might want to use them is if cabal doesn't know about the extension yet. This could be solved by a --language=E flag that GHC treats identically to -fe. Obviously cabal can't check that GHC supports this extension in advance (so would have to assume that it does), but at least we no longer have any need to enable extensions with method 2 or 4. We could also then have Cabal always pass a --no-extension-flags flag, which would mean that GHC would reject -fe. That wasn't the contentious bit, so hopefully you aren't too inflamed yet! Suppose we agree that we should only use method 1; there are a number of issues: * If someone uses method 3, no alarm bells will sound. The package will continue to build where it can be built. * The same set of extensions is used for every module. For example, if you want to allow overlapping instances in one particular place[1] then you must allow them everywhere. * If you want to load one of the modules in ghci, say, then you need to tell it what flags to use. Thus I propose that the .cabal file actually specifies what extensions the modules are /allowed/ to use, but does not actually enable them. They would then be enabled by LANGUAGE pragmas in the modules as necessary. So, if the .cabal file says "Extensions: E, F" then the modules will be compiled with --no-extension-flags --allowed-extension=E,F and if a module has "{-# LANGUAGE E #-}" then only extension E would be enabled for that module. If a module has "{-# LANGUAGE E,G #-}" then compilation would fail as extension G is not permitted. Any comments? Criticisms? Flames? Thanks Ian [1] Currently we can only specify this to a file-level granularity, but in principle you could imagine more localised pragmas, like we have for unboxed fields.

SoC proposal: Implement Cabal configurations
by Björn Bringert 24 Mar '07

24 Mar '07

I want Cabal configurations, so I added a SoC proposal for it, see http://hackage.haskell.org/trac/summer-of-code/ticket/1131 This was the latest spec I could find: http://www.mail-archive.com/cabal-devel@haskell.org/msg00282.html I haven't taken part much in the configurations discussions, so I'm not sure how finished the spec is or if it would be a good SoC project. Feel free to comment on / change the proposal as you see fit. /Björn

Automatically running autoreconf?
by Bryan O'Sullivan 16 Mar '07

16 Mar '07

The fact that most packages don't have autoconf encumbrances means that I almost inevitably forget to run autoreconf before building a package, which regularly leads to heartburn on my part. It seems to me that it would be useful if "build" ran autoreconf if necessary. If this seems sane, I would be happy to cook up a patch. What do people think? <b

darcs patch: setup makefile
by Simon Marlow 14 Mar '07

14 Mar '07

I'm sending this patch here to solicit comments. Ian Lynagh has been converting GHC's build system to use Cabal for packages instead of our current Makefile setup. There are a couple of things that don't work as well with Cabal: (1) we can't use 'make -j' and get parallel builds, and (2) we can't build individual files and give extra options on the command line: this is occasionally very useful when debugging the compiler or testing small changes. So we could fix these with brute force: I have patches to make GHC --make work in parallel, but it needs a lot of work to make it robust. We could add support to Cabal to build a single file and give extra options on the command line, but most people don't need this. Instead, I decided to address both of these in one go: the idea is to have Cabal generate a Makefile that you can use with 'make -j' or to build a single file with 'make dist/build/Foo.o', for example. It only works with GHC, and only for libraries (I could probably make it work for executables too, just haven't done that yet). It does work with profiling, and as far as I can tell everything else works, because GHC gets invoked with almost exactly the same arguments as with 'setup build', except that it is invoked one file at a time. This is really the missing piece needed to let GHC use Cabal for its build system, so I'm pretty keen for this to go in. Comments? Cheers, Simon New patches: [Add 'setup makefile' command Simon Marlow <simonmar(a)microsoft.com>**20070309155022 'setup makefile' generates a Makefile that performs the steps necessary to compile the Haskell sources to object code. This only works for libraries, and only with GHC right now. Instead of simply 'setup build', you can do this: $ ./setup makefile $ make $ ./setup build where './setup makefile' does the preprocessing and generates a Makefile tailored to the current package. 'make' will build all the Haskell code to object files, and 'setup build' will build any C code and the library archives. The reason for all this is that you can say 'make -j' and get a parallel build, or you can say make dist/build/Foo.o EXTRA_HC_OPTS=-keep-s-file to compile a single file with extra options. ] { hunk ./Distribution/Make.hs 172 + + MakefileCmd -> exitWith ExitSuccess -- presumably nothing to do hunk ./Distribution/Setup.hs 52 + MakefileFlags(..), emptyMakefileFlags, hunk ./Distribution/Setup.hs 62 + parseMakefileArgs, hunk ./Distribution/Setup.hs 97 + | MakefileCmd -- makefile hunk ./Distribution/Setup.hs 253 + +data MakefileFlags = MakefileFlags {makefileVerbose :: Int, + makefileFile :: Maybe FilePath} + deriving Show +emptyMakefileFlags = MakefileFlags {makefileVerbose = 1, + makefileFile = Nothing} + hunk ./Distribution/Setup.hs 263 --- |Most of these flags are for Configure, but InstPrefix is for Copy. +-- | All the possible flags hunk ./Distribution/Setup.hs 302 + -- For makefile: + | MakefileFile FilePath hunk ./Distribution/Setup.hs 391 -commandList progConf = [(configureCmd progConf), buildCmd, cleanCmd, installCmd, +commandList progConf = [(configureCmd progConf), buildCmd, makefileCmd, + cleanCmd, installCmd, hunk ./Distribution/Setup.hs 609 +makefileCmd :: Cmd a +makefileCmd = Cmd { + cmdName = "makefile", + cmdHelp = "Perform any necessary makefileing.", + cmdDescription = "", -- This can be a multi-line description + cmdOptions = [cmd_help, cmd_verbose, + Option "f" ["file"] (reqPathArg MakefileFile) + "Filename to use (default: Makefile)."], + cmdAction = MakefileCmd + } + +parseMakefileArgs :: MakefileFlags -> [String] -> [OptDescr a] -> IO (MakefileFlags, [a], [String]) +parseMakefileArgs = parseArgs makefileCmd updateCfg + where updateCfg mflags fl = + case fl of + Verbose n -> mflags{makefileVerbose=n} + MakefileFile f -> mflags{makefileFile=Just f} + hunk ./Distribution/Simple/Build.hs 46 -

darcs patch: Fix profiling executable with template haskell
by Judah Jacobson 14 Mar '07

14 Mar '07

Attached is a patch to fix a bug that I found when trying to compile an executable for profiling with ghc when my modules used template haskell. Cabal is smart enough already to accomodate TH by compiling everything twice (first the regular way, then with profiling). However, the second compile is missing ghc's -osuf and -hisuf arguments (as in the GHC manual, section 7.6.4). This patch adds those arguments at the right time; I've tested it against my own repositories and it seems to work fine. Best, -Judah
