Ajhc - arafura-jhc

A fork of jhc. And also Haskell compiler.

This project is founded by Metasepi Project.

How to install

$ cabal install ajhc

How to build latest version

$ sudo apt-get install make locales autoconf libreadline-dev \
  libwww-perl libconfig-yaml-perl graphviz haskell-platform drift pandoc \
  libghc-readline-dev libghc-utf8-string-dev libghc-hssyck-dev
$ git clone git://github.com/ajhc/ajhc.git
$ cd ajhc
$ git checkout arafura
$ autoreconf -i
$ ./configure
$ make cabal-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).

Needing to install/build on Windows (currently in progress)

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

Install DrIFT

$ cabal install DrIFT-cabalized

Future plan

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.masterq.net/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.

Yet

• No more depend on DrIFT. Use http://hackage.haskell.org/package/derive.
• No more depend on Perl (LWP and YAML).
• Support LPCXpresso NXP LPX1769 with demo.
• Rewrite Cortex-M3 base library with Ajhc.
• Pass all regress test, and enable regress fail setting on travis-ci. https://travis-ci.org/ajhc/ajhc
• Analyze jhc internal (Japanese doc). http://metasepi.masterq.net/posts/2013-01-31-jhc_internal_overview.html
• Find critical region of Ajhc for reentrant and thread safe.
• Port Haskell libraries on haskell-platform to Ajhc.
• Understand jhc's region inference.
• Find the method to implement GC that can be interrupted.
• Get smaller RTS. Benchmark the RTS for running on custom FPGA CPU.
• Start rewritng NetBSD kernel with Ajhc.
