Ajhc - arafura-jhc

A fork of jhc. And also a Haskell compiler.

This project is founded by Metasepi Project.

How to install

$ cabal install ajhc

How to build latest version

$ git clone git://github.com/ajhc/ajhc.git
$ cd ajhc
$ git checkout arafura
$ autoreconf -i
$ ./configure
$ make
$ make install

For developing

First, you should use the arafura branch, rather than master branch.

• master branch: Do not touch me, mirror of jhc's darcs repository.
• arafura branch: For developing Ajhc.

You should send patch to jhc, if testing on Ajhc is good.

$ darcs get http://repetae.net/repos/jhc
$ cd jhc/
$ patch -p1 < ~/yourfile.patch
$ darcs record -a
$ darcs send

The command darcs send sends email the patch to jhc author (= John Meacham).

Perhaps you can get internal overview with following compile flow image:

Needing to install/build on Windows (experimental)

Install msys

http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/

Install below.

• C Compiler
• MSYS Basic System
• MinGW Developer ToolKit

You should run cabal install on msys console.

Install Git for Windows

http://msysgit.github.com/

It's good choosing the below option.

• "Checkout as-is, commit as-is"
• "Run Git and included Unix tools from the Windows Command Prompt"

Install Haskell Platform

http://www.haskell.org/platform/windows.html

Future plan

Yet

• No more depend on Perl (LWP and YAML).
• Rewrite Cortex-M3 base library with Ajhc.
• Analyze jhc internal (Japanese doc). http://metasepi.org/posts/2013-01-31-jhc_internal_overview.html
• Port Haskell libraries on haskell-platform to Ajhc.
• Understand jhc's region inference.
• Play with Android NDK. http://developer.android.com/tools/sdk/ndk/index.html
• Play with Google Native Client. https://developers.google.com/native-client/
• Play with Nintendo DS. http://devkitpro.org/wiki/Getting_Started/devkitARM
• Snatch ChibiOS/RT. http://www.chibios.org/dokuwiki/doku.php
• Write Linux kernel driver with Haskell.
• Get smaller RTS. Benchmark the RTS for running on custom FPGA CPU.
• Start rewritng NetBSD kernel with Ajhc.

Done

• Try to rewrite a part of NetBSD bootloader. http://www.youtube.com/watch?v=JMyxy5Qo2m8
• Translate Jhc User’s Manual to Japanese. http://metasepi.org/posts/2013-01-12-jhc_manual_ja.html
• Fix bug that run stm32f3-discovery demo. It causes Ajhc RTS heep impl. https://github.com/ajhc/demo-cortex-m3/tree/master/stm32f3-discovery
• Support to build on Windows.
• Cabalize Ajhc. Ajhc's hl files will be not controled with cabal.
• Support LPCXpresso NXP LPX1769 with demo.
• Pass all regress test, and enable regress fail setting on travis-ci. https://travis-ci.org/ajhc/ajhc
• No more depend on DrIFT. Use http://hackage.haskell.org/package/derive.
• Find critical region of Ajhc for reentrant and thread safe.
• Find the method to implement GC that can be interrupted.
