Eruta is a futuristic Japanese style RPG under development.
* OS: Linux for now. Windows port is under development. OSX may work too.
* Allegro 5.1.9 or later.
Earlier versions won't be found by the build script.
* libxml2 (www.xmlsoft.org)
* mruby (latest gitub version). To install globally in /usr/local
`cd ; make ; sudo bin/install_mruby`
to compile and install mruby into /usr/local
* For compilation: cmake 22.214.171.124 or later (see vendor directory), make or ninja.
* For development: cproto to generate header files.
* For testing and debugging: gdb, ddd, valgrind.
* For map editing: tiled (www.mapeditor.org)
* For some of the tools and continuous testing: Ruby, watchr.
You have to make sure that you have all the requirements. On Linux
distributitions like Ubuntu, make sure that the development packages for all
requirements are installed. Then do on the command line:
cmake . ; make
Or if you want to build with Ninja, use the latest version of cmake and go
cmake -G Ninja . ; ninja
Please note that cmake and the word "Ninja" is case-sensitive!
How to try it:
Run bin/eruta from the project's main directory.
Expect to be underwhelmed for now. :-)
How to develop using the contious testing script:
Use the supplied watchr script like this:
Every time you change a c file or header, the matching
test will be compiled though cmake and make, and
will be run. This does compile all C files of eruta,
so it may be a bit slow at times.

As you can see, above, Eruta is licenced under a "Sleepycat license", which is
GPL compatible, but much shorter and easier to read. Basically you're allowed
to use the Eruta as you like. However, if you make your own game with Eruta's
sources, you'll have to make the sources of your program freely available and
redistributable as well. If you don't like these terms, contact me for making
different arrangments. :)

Remarks for developers:
The header files are partially automatically generated using the cproto tool.
The documentation should therefore be written in the C files.
When a new .c file is needed, use the bin/newmodule tool like this
and automatically, empty src/bar.c and include/bar.h will be generated.
As for why I use plain C and not, say C++: it's to keep the code simple, tight
and focused, and easy to interface with the Ruby scripts. C is a very simple
language, but it can do anything and it does it fast. And to save time, quite
a bit of the programming will happen on the mruby side.
An overview of the C files andwhat they are about:

Since I try out a lot of things, ther are quite a few unused C fils in
