2014-04-12 BMFont has gone open source
I've decided to celebrate the 10 year anniversary of the Bitmap Font Generator tool by opening up the source code to the public.
The license model I chose is the same as I use for my other projects, angelscript and the tool box, i.e. the zlib license. This will allow you to use the code unhindered by any restrictive clauses in the license.
If you do make any improvements to the code I would very much like to see them, and even incorporate them into the svn for others to benefit from them too.
2014-03-18 AngelScript 2.28.2
My primary goal with this version was to implement the grid add-on, which basically a 2D array with rectangular dimension. Multi-dimensional were already supported in the script language as arrays-of-arrays, but this would often become cumbersome to work with when a rectangular area was wanted as each subarray had to be resized individually. Accessing elements in arrays-of-arrays is also not particularly efficient as there is a lot of overhead.
In order to properly support the grid add-on (and any other multi-dimensional array implementation that developers imagine) the library was enhanced to allow multiple arguments in the opIndex overload, and the list pattern declaration gained a new keyword 'repeat_same' to tell the compiler that all sub-lists should be of the same size.
The grid add-on itself is currently quite basic with very little functionality besides setting up a 2D area and allowing the script to access the elements, but it serves it's main purpose of showing developers how multi-dimensional arrays can be implemented. Ideas for how to make it a truly useful add-on are most welcome.
Other enhancements in this version that are worth mentioning include; added support for opCall operator to allow the implementation of functor objects in scripts, implemented support for anonymous objects initialized with lists, improved compiler rules for implicit casts in expressions, reduced size of saved bytecode, more efficient bytecode sequences.
Some other add-ons have also received improvements. The array add-on now supports custom memory routines (a side effect of this, is that when instantiated from C++ it is now necessary to use factory functions instead of allocating with new). The dictionary add-on has received enhancements to improve interaction from the C++ side with a method to retrieve the type id of a stored value, and an iterator with support for C++11 range-for loops. The math add-on also has a new function closeTo() that should be used to compare floats or doubles when one wants to do approximate comparisons to handle numerical impression in float and double calculations.

It's time for the first release of 2014.
This one brings quite a lot of under-the-hood improvements, such as reduced compilation times, less overhead in calling script interface methods, inline allocation of class members, reduced size of saved bytecode, improved error reporting for loading invalid bytecode, automatically resolve ambigiuous enum values, etc.
The script language has a new built-in math operator ** for calculating the exponent. Of course, this operator is overloadable just like the rest of the operators. This operator also added 7 new instructions for the VM to handle the primitive types.
Several of the add-ons have been tweaked and adjusted to make them easier to use.
Some of the improvements in this release were contributed by the community members GGLucas and Jason Goepel. So thanks should go out to them this time.

With this version I've spent a lot of time to redesign how the initialization lists work. Previously they could only be used for arrays, but now the application can register a list factory, or list constructor for value types, and declare a pattern that should be used by the compiler. The compiler will also build a single buffer with all the value and pass a pointer to that buffer to the factory or the constructor. This makes it much more effective to copy the values into the object in comparison with the previous use of the index operator.
The new initialization lists are a lot more versatile, and I've used this to implement a list factory for the dictionary add-on that takes name-value pairs, and also a list constructor for the complex math type to show how it is done.
Hopefully this will make AngelScript much more useful as a data language, i.e. where the scripts are used to setup data besides just for logic.
There is of course a lot more than can still be improved with regards to the initialization lists, and I'll continue to work on this over the upcoming releases. Some examples of future improvements are the ability to use initialization lists in regular expressions, and more rules that can be given to declare the expected list pattern.
The release brings several other minor improvements too, so please verify the change list to get the details.
