Monster - 0.14
==============

Written by Nicolay Korslund
Email: korslund@gmail.com
WWW: http://monsterscript.net/
Current status: alpha

Monster is currently licensed under version 3 of the GNU Public
License. License information can be found in GPL3.txt. Exceptions to
the license and copyright are noted in certain files.



Installation
=========================

To compile Monster you need a fairly recent D compiler, which you can
find at http://digitalmars.com/d/. Make sure to get a compiler from
the 1.0 (stable) branch, not the 2.0 (unstable) branch. You should
also be to compile Monster with the GNU implementation of D (GDC) as
well. DMD 1.046 is specifically known to work. The LDC compiler has
not been tested with Monster yet.

To build Monster you will also need DSSS, the D Shared Software
System. You can find DSSS at: http://www.dsource.org/projects/dsss

Monster supports both Phobos and Tango standard libraries out of the
box, and the installation instructions for both are identical.

Once you have DSSS and a D compiler set up, unpack the archive file.
On linux, do:

tar xvzf monster-X.X.tar.gz

where X.X is the version number. Windows unpackers such as winrar and
7zip can also be used to unpack tar.gz files. This will create a
directory called monster-X.X. Then do:

cd monster-X.X
dsss build
dsss install

If dsss is set up correctly, the example VM (mvm) should now be in
your PATH.



Running the Examples
=========================

After compiling and installing Monster, you should be able to run the
individual example files in the examples directory. This is done with
the 'mvm' program (which should now automatically be in your PATH.)
Try the following:

cd examples/mvm
mvm hello          (or 'mvm hello.mn')

Most of the example files have comments describing what they do.

There are more examples, although not as user friendly, in the tests/
directory.

Some examples produce stand-alone programs, written in D and C++.
There are three versions of each example, one for D with phobos (the
default standard libarary), one for D with Tango (alternative
library), and one for C++. See the next two sections for instructions
on how to compile and run these. The Monster files (.mn) are identical
in all three versions, and the native sources (.d and .cpp) have been
made as identical as possible. The Monster API aims to be consistent
across languages and platforms.



Compiling D Examples
=========================

To compile the D examples, do:

cd examples/phobos
dsss build
cd sdltest
dsss build

If you are a Tango user, use the examples/tango directory instead. You
must compile and install the library and main binaries (see previous
section) BEFORE you compile the examples, or else they will not
work. The example files can then be run and examined in place, you do
NOT need to run 'dsss install' in the examples directory.

The sdltest example requires DerelictSDL and libsdl. To install
DerelictSDL automatically, enter the sdltest directory and type

dsss net deps

The libSDL runtime (SDL.dll on windows) is also needed, and can be
found at libsdl.org or through your linux package manager.

(Note to Linux users: dsss net commands also depend on curl, which is
not installed by default on some distributions. On Ubuntu for example,
do 'sudo apt-get install curl' before using the net commands.)



Compiling C++ Examples
=========================

NOTE: These instructions are designed for a unix environment. They
will possibly work under CygWin on Windows with a few modifications,
but this has not been tested yet. Linking with Tango is not yet
supported.

Before you can run the C++ examples you have to compile the library
file in lib/ :

cd lib
makelib

This should produce the files libMonster.a and libCppMonster.a in the
lib/ directory. You also need to make libphobos.a (which comes with
DMD) accessible. For example you can put a link to it in the lib/
directory:

cd lib
ln -s /my/path/to/dmd/lib/libphobos.a .

The C++ examples can then be compiled with GNU make. Note that you
must have the SDL library and C headers installed on your system for
sdltest to compile.

- Compiler (mcc) and compiled files (.mc) are gone.
- Renamed file extension from .m to .mn to avoid editor conflict with
  Matlab scripts.

  examples/properties.mn for a list.
- Multiple script include directories - just do classes.addPath("dir").
- 'codetml' program for easy translation .mn -> html

- Dynamic arrays. Syntax and semantics work pretty much like in D.
- Dynamic creation of single or multi-dimensional arrays.
- Array and string literals.
- Foreach loops, with type deduction, optional index and ref elements.

- dsss.conf for examples updated to work on windows
- resolved a circular module dependency issue on windows

0.4-prealpha (2008-jan-31)

- Labels, goto and halt statements can now be used in state code.
- Labels can be specified when changing state.
