Re: [Haskell-cafe] Does GHC 7.8 make targeting bare metal ARM any easier?
Hello Jeremy, I'd also like to see GHC compiling for ARM bare metal. Honestly speaking I've avoided Raspberry Pi, but rather settled on ARMv7. Side note: BeagleBone is excellent for this as you get all the TI supported tools together with JTAG debugging just for free from TI (including ARM compilers if you care about this) and also you get full documentation for its Sitara 335x SoC. Anyway, back to the GHC topic. I find it too invasive to go straight from POSIX/libc dependency to nothing on bare-metal. Instead of this while analyzing the situation for myself I've rather settled on POSIX RTOS which is much less weight that general purpose Linux distro and yet it provides a lot of API which makes GHC RTS porting work much easier. So as my hobby time permits I'm working on GHC port to RTEMS[1] which is a single-process, multi-threaded RTOS with POSIX API supported. On its devel mailing list you may find that Raspberry Pi BSP was already submitted for inclusion. Generally speaking, I also hope that since this work is much less invasive on GHC, it has higher chance of a merge into GHC HEAD once ready... Cheers, Karel [1]: http://www.rtems.org/ On 03/20/13 02:07 AM, Jeremy Shaw wrote: There have been at least a couple projects, such as hOp and HaLVM which attempt to run GHC on the bare metal or something similar. Both these projects required a substantial set of patches against GHC to remove dependencies things like POSIX/libc. Due to the highly invasive nature, they are also highly prone to bitrot. With GHC 7.8, I believe we will be able to cross-compile to the Raspberry Pi platform. But, what really appeals to me is going that extra step and avoiding the OS entirely and running on the bare metal. Obviously, you give up a lot -- such as drivers, network stacks, etc. But, there is also a lot of potential to do neat things, and not have to worry about properly shutting down an embedded linux box. Also, since the raspberry pi is a very limited, uniform platform, (compared to general purpose PCs) it is feasible to create network drivers, etc, because only one chipset needs to be supported. (Ignoring issues regarding binary blobs, undocumented chipsets, usb WIFI, etc). I'm wondering if things are any easier with cross-compilation support improving. My thought is that less of GHC needs to be tweaked? - jeremy ___ Glasgow-haskell-users mailing list glasgow-haskell-us...@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

[Haskell-cafe] DSL for data definition (e.g. compiling Haskell type defs into Google's protocol buffers type defs)
Hello,
I'm trying to find out if it's possible to use Haskell data type
definition capability to define types and compile defined types into
other languages, for example into Google's protocol buffers data
definition language. So basically speaking I'm thinking about using
Haskell sub-set as a data-definition DSL together with some functions
which will generate some code based on supplied defined data types. My
idea is:
data Person = Person {
id :: Int
, name :: String
, email :: Maybe String
}
deriving (Show, Data, Typeable)
emit_proto Person 1
where emit_proto is function which will translate Person data type
definition into Google's proto language (the 1 is index from which start
to index type's fields) by traversing data type definition and
translating all its children plus do some header/footer generation etc:
message Person {
required int32 id = 1;
required string name = 2;
optional string email = 3;
}
I've looked for something like that and found SYB papers which works on
top of data instance (i.e. actual data, not data type). I also found
JSON lib which again works on top of data and not data type. I've tried
to look into Data.Typetable etc, but have not found function which will
print data type's field name and field type name (although JSON lib
seems to use field name for JSON generation so I'll need to investigate
this more). I've tested `typeOf' function and it's quite useful, but its
limitation is that it's not working on ADT name:
data Color = RED|GREEN|BLUE
*Main typeOf Color
interactive:1:8: Not in scope: data constructor `Color'
*Main typeOf RED
Main.Color
and I would need that in order to translate Color defined above into
enum like:
enum Color {
RED = 0;
GREEN = 1;
BLUE = 2;
}
My question is: do you think I'm looking into good direction (i.e.
Data/Typeable) or do you think I'll need to use something different for
data definition DSL (Template Haskell?, or impossible in Haskell so
write my own language with full parser? etc?)
Thanks for any idea or opinion on this!

Re: [Haskell-cafe] DSL for data definition (e.g. compiling Haskell type defs into Google's protocol buffers type defs)
Hello,
thanks a lot to Edward, Jose, Ryan and Stephen for fast reply in this
thread. I see I've not been that precise in specification of what I need
exactly so I need to add this: I've changed a little bit definition of
person to:
data PersonType = Person {
id :: Int
, name :: String
, email :: Maybe String
}
deriving (Show, Data, Typeable)
so I have `PersonType' as type constructor and Person as value
constructor (or data constructor) -- speaking using terms from Real
World Haskell, Chapter 3[1]. And now I see that none of
typeOf/dataTypeOf/toContr is applicable to *type constructor* but all
are applicable to *value/data constructor*. Ditto happen when testing
Color versus RED, GREEN, BLUE. At least GHCi complains this way:
*Main typeOf Color
interactive:0:8: Not in scope: data constructor `Color'
*Main typeOf PersonType
interactive:0:8: Not in scope: data constructor `PersonType'
But, I'd like to start processing of data definition from the *type
constructor*. So:
emit_proto PersonType 1
emit_proto Color 1
Is that possible at all? I mean in the scope/context of GHC's
Data/Data.Data/Data.Typeable etc. modules. (w/o considering TH now).
Thanks!

I think it will be simpler for you to get gentoo's ia64 binaries (unregisterised) and bootstrap ghc-HEAD yourself. http://code.haskell.org/~slyfox/ghc-ia64/ghc-bin-6.12.3-ia64-haddock.tbz2 http://mirrors.kernel.org/gentoo/distfiles/ghc-bin-6.12.3-ia64-haddock.tbz2 We, gentoo, apply patches for ghc-6.12.3 to make magic happen (all gone upstream and ghc-7.0/ghc-7.0.1) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ In case you will decide to bootstrap stable ghc-6.12.3 the following patches should suffice. == required patches == * GC patch (the critical one, fixes bug you have posted) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-storage-manager-fix.patch?revision=1.1view=markup * you need to pass -G0 to gcc when you build ghc. Gentoo does it in a special manner: we add the following to mk/build.mk: SRC_HC_OPTS += -optc-G0 Your approach might be different. It solves known(?) limitation of small object's section size. == nice to have patches == * remove crufty linker flags in order to able to link ghc on recent binutils http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-fixed-relax.patch?revision=1.1view=markup * f.i.w calls on ia64 (fixes terminfo and thus interactive darcs, otherwise it will SIGSEGV) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ia64-use-libffi-for-foreign-import-wrapper.patch?view=markup * If you plan to build haddock using unregistered ghc you'll need one more patch to export needed API (backported from -HEAD). http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-lang/ghc/files/ghc-6.12.3-ghciless-haddock-3558.patch?revision=1.1view=markup Good luck! ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] GHC 6.8.2 on IA64-Linux platform (Itanium)

The goal of the Manatee project is to provide a fast, safe and flexible integrated environment for haskell hacking. You can consider it is new environment mix Gnome and Emacs. Like Gnome to provide friendly graphics interface and work efficient like Emacs. Manatee use multi-processes framework, any sub-module running in separate process to protected core won't crash. So it minimize your losses when some unexpected exception throw in extension. Now i have implement below sub-modules in Manatee: Editor Webkit Browser File Manager Image Viewer IRC Client Multimedia Player PDF Viewer Process Manager RSS/Atom reader From some friends feedback, manatee can't work in XMonad, i will fix it soon. You can play it in Gnome. Enjoy! :) Below are steps to build Manatee: 1) Install C library: In Debian use below command: sudo aptitude install libgtksourceview2.0-dev libgconf2-dev libwebkit-dev libcurl4-openssl-dev libgtkimageview-dev libpoppler-glib-dev poppler-data libtagc0-dev -y 2) Install Gtk2hs: cabal install gtk2hs-buildtools gtk And make sure HOME.cabalbin/ in your PATH. 3) Install Manatee: cabal install manatee-core manatee-anything manatee-browser manatee-editor manatee-filemanager manatee-imageviewer manatee-ircclient manatee-mplayer manatee-pdfviewer manatee-processmanager manatee-reader manatee That's all, then type command manatee to play it! :) manatee-core manatee-anything manatee are core packages, must be install, other extension package you can choose you want. Example, if you not install manatee-imageviewer, when you open Image file, manatee will call default image-viewer in your system instead. Manatee will show you search interface when you startup it. You can type some filepath or url to open it, example, you can type Haskell file to open in editor, and type url to open in browser. Below are quick play keys: F2 == startProcessManager F3 == startFeedReader F4 == startFileManager F5 == startBrowser F6 == loginIrcDefaultChannel F7 == startIrc Manatee project still in early develop stage, just core framework finish, many details still not perfect. But i think it's good start to build Real-World application in Haskell. Below are high task in my TODO list: Perfect current sub-module: IDE features, code completion browser JavaScript framework graphics custom system etc. Terminal emulator: support MVC design, not like VTE widget Mail-client BT-Client Proxy bridge: to build uniform proxy interface to fighting GFW!!! Jabbar client: video support etc. Spell checker CHM viewer DVI viewer LaTex editor PS viewer Multi-thread download manager Org-Mode : http://orgmode.org/ Twitter client Network toolkit: sniffer etc. Multi-Language translater offline support Too many ideas lying in my TODO
[Haskell-cafe] Haskell/JDK/tail-calls etc. (please vote on bug No. 6804517)
Hello, from time to time request for Haskell running on top of Java's VM pops on the haskell related mailing list and then usually dies off when someone mentions that JDK does not have proper support for tail-calls. I think haskell community might do something with this fact or at least attempt to do something with it. I think the proper request for enhancement is here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6804517 if you agree with it (as it's proposed on the rfe's mentioned blog article[1]), then please either join or if you are already a member of SDN then just login and vote for this bug.

[Haskell-cafe] CAL experience
Hello, as this is really friendly forum, I'd like to ask to perhaps solve my wonder. From time to time I'm seeing people here recommending Scala as a kind of replacement for non-existent Haskell on Java/JVM platform. My wonder is: why the people here do not recommend CAL, which at least to me, looks much more closer to Haskell than Scala is. Are there any bad experiences with this language and OpenQuark platform? I'm asking since I'm currently playing with it and plan to use it for java objects data processing.
