License

Monster is currently released under the GNU General Public License (GPL) version 3 only. More license options are planned in the near future.

Source releases

Monster is alpha software! Some features might still be missing or incomplete.

The source releases require a D compiler, but can be used both with D and C++.

monster-0.12.tar.gz - 295k - 2009 May 04 (latest release)
monster-0.11.tar.gz - 265k - 2009 Feb. 18
monster-0.10.tar.gz - 237k - 2008 Nov. 19

Subversion

For the latest sources (not necessarily stable), check out the Subversion trunk:

svn co https://monster-script.svn.sourceforge.net/svnroot/monster-script/trunk monster

This will put the source code in a directory called 'monster'. To update to the newest version at a later point, just enter this directory and type:

svn up

You can also check out specific releases, like this:

svn co https://monster-script.svn.sourceforge.net/svnroot/monster-script/tags/monster-0.9 monster-0.9

Obtaining a D compiler

The Monster library requires a fairly recent D compiler. Currently the only tested compiler is the 1.0 (stable) branch of DMD. You can download DMD here. For installation instructions check out the official DMD installation page. The GNU D compiler (GDC) is also known to work. In addition to a compiler you will also need to install DSSS, the D Shared Software System, in order to build Monster.

Note to C++ users: You do not need a D compiler to use the library, only to compile it.

Compiling Monster

Unpack the Monster archive and change to the resulting directory. For example, on Linux you do:

tar xvzf monster-X.X.tar.gz
cd monster-X.X

Once you are in the correct directory, compile and install Monster (on all platforms) with:

dsss build
dsss install

This will build and install the example VM (mvm) and the library. For further instructions see the included README.txt.

Changelog

A more detailed changelog + developmers log can be found in the Wiki.

package system, based on directories
semicolons are now mostly optional
added vm.load() and family for class loading, replacing MonsterClass constructors
class constructors
assignment is now a statement, not an expression
can set object variables upon creation with 'new'
named function parameters
optional function parameters
initial value of class variables can changed in child classes
initial state can be set in class declarations
improved stack trace functionality
enums
module for interactive mode and ingame consoles
new file options.d, customize the language and VM at compile time
thin virtual file system (VFS) abstraction, allows using external libraries to read scripts from archives
all initialization is automatic: InitMonster() and initAllModules() are gone.
bindNew, allows a callback function for newly created objects
explicit casting, of the type int(3.4) or MyClass(obj)
implicit downcasting of objects
numerous bug fixes and improvements

See the Wiki changelog for detailed descriptions.

0.11 - Alpha - 2009-feb-18

first alpha release
complete inheritance and polymorphism
abstract, final and override function keywords
support for non-class (run-once) script files
modules and import statement
typeof and var
virtual thread system is much more versatile and no longer restricted to object state code
idle functions can be called anywhere
idles/vthreads can be used as (asymmetrical) coroutines

0.10 - 2008-nov-19

Further merged the compiler and VM. Classes can now be created at runtime and through API calls.
Removed the 'classes' struct, as the linking phase is no longer necessary.
Four new types: uint, long, ulong and double
Const array references: new array properties .const and .isConst
'const' modifier for function parameters (for arrays only)
Array/string literals are now constants
Improved memory performance for array literals
Object cloning: obj.clone in Monster and mo.clone() in D/C++
Floating point reminder (%) and integer division (\) operators
BOM markers are now recognized
Ignore first lines beginning with #! (for unix scripts)
Fixed incompatibility with DMD 1.032+ (thanks to tomqyp)
Created 'tests' directory, reorganized examples
Bug fixes and minor improvements

0.9 - 2008-aug-27

Simple inheritance (no function overriding or polymorphism yet)
Major rewrite: merged compiler and VM
Much more information at runtime: variable names/types, function parameters, etc
Read and write directly to class variables from native code
Compiler (mcc) and compiled files (.mc) are gone
Renamed file extension from .m to .mn to avoid editor clash with Matlab
Added generic type properties, like int.max, float.nan, etc. See examples/properties.mn for a list
Multiple script include directories - just do classes.addPath("dir")
'codetml' program for easy translation .mn → html
Lots of minor improvements

0.8 - 2008-apr-21

String concatination.
Foreach on a class can loop through instances.
Autogen programs now handle arrays correctly.
Tango and C++ versions of the program 'mvm'.
Better error handling in C++, exceptions can now "pass through" the interface (experimental.)
Fixed the foreach ref bug and some other minor issues.
Internal: cleanup and refactoring of compiler/scopes.d.

0.7 - 2008-mar-12

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.
Easy interface to pass arrays to and from native code (also for C++.)
Array vararg function parameters.
Break and continue in loops, with support for loop labels.
Case insensitive string comparison operator: =i= and =I=.
Changed syntax of empty state to "state = null;"
Moved several mvm-based examples to examples/
Implicit type conversions: int -> float, all types -> char[].
Various small improvements and bugfixes.

0.6 - 2008-feb-19

Added a Tango compatability layer ("minibos".) Monster now supports Tango "out of the box".
Created dexamples-tango/ with Tango versions of all the examples.
The VM will now compile script files automatically. You no longer need to run mcc.
Removed hard coded function "writeln".
Cleaned up shared/mcfile.d and finalized numbering in shared/bytecode.d
Removed expensive consistency checks from util.list (add debug=slowcheck to bring them back.) This should improve performance of sdltest.

0.5 - 2008-feb-07

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

0.4 - 2008-jan-31

Labels, goto and halt statements can now be used in state code.
Labels can be specified when changing state.
States no longer loop automatically. Existing code must be updated.
Improved dsss.conf files and restructured directories for better compatability with DSSS.
Hugely simplified scope handling code in the compiler, and rewrote the entire type system.
D version of 'sdltest' switched to DerelictSDL.
All makefiles have been removed, except the ones that compile C++ examples.

0.3 - 2007-dec-30

Made some workarounds to avoid DMD template bugs
Full support for DSSS and Rebuild
Should also work with GDC now (not extensively tested.)
Example 'sdltest' can turn off graphics with the 'g' key
C++ file monster.h is somewhat more const correct
Compiler mcc prints file names to stdout

0.2 - 2007-dec-20

C++ bindings
All examples are now implemented in both D and C++
Binary (static library) download for C++ (no D compiler required)[1]
New utility programs (autogen_d, autogen_c) that automate creation of native code for D and C++
Completely removed the redundant 'void' type from the language
Compiler 'mcc' can compile multiple files at once (eg. 'mcc *.m')
More examples, including SDL example
Restructured the vm code quite a bit
Can now bind functions (as well as delegates) to native functions
Added util/freelist.d and util/growarray.d and several other files
Multiple classes and object now fully implemented (but no inheritance yet)
Lots of small improvements and bug fixes

[1] Binary downloads have been removed again, they simply took too much work to maintain. They will return in the future.
