Coding Guidelines

Compilers

On linux, it should be buildable using g++ -std=c++11, tested with g++ 4.8
On Windows, Visual Studio 2015, tested with Visual Studio 2015 community edition

Templating

not using templating, since it makes writing wrappers for scripting languages harder
it also causes cryptic debugging messages

Callbacks, inheritance by client

callbacks are poorly supported when using from scripting languages, as are classes that need to be overridden by the client script/code

Building

Building is mostly done using cmake.

cogapp

cogapp generator is used extensively, to accelerate development, reduce the number of manual copy-and-pasting and so on. Specifically, it's used for:
- generating header declarations from .cpp definition files
- generating fluent-style argument classes for certain tests
- ... and more uses will surely be found :-)
You need Python installed and available for this to work. You don't need python just to build the sources, but if you do have python installed, and you flip the PYTHON_AVAILABLE(note: might have changed names recently :-P ) switch in the cmake configuration, then a lot of manual editing will no longer be necessary :-)

Formatting

whitespace:
- I've been using eg foo( somearg, argtwo ), but will probably change to foo(somearg, argtwo), since that's same as pep8, and torch also uses this standard
- no whitespace in between functions in .cpp files (to reduce scrolling)
braces: { at end of previous line, like if(foo) {
