Situation:
Mac OS, Arduino IDE 1.5.6r2
I've got a sketch with several files, all classic .cpp and .h source and header files except the main sketch file. As the project goes more complex I started to generate code automatically by another program. Now I have hard times integrating the generated code it into my sketch. The arduino IDE seems to load the code on opening the sketch. After that, the source files aren't beeing checked for external changes by the IDE (as I would expect it from a real editor like vim). On top of that, when I verify my code the IDE seems to save the files from RAM into a temporary build directory ignoring the contents of the sketch directory further. So if I let my code generator change a source file while the sketch is opened in the IDE, the changes won't reach the build. I had to close the IDE and reopen it. The next thing I tried is to include my autogenerated file from an existing and opened code file inside the IDE. But the IDE ignores files, which aren't opened completely. Hence, the file is missing in the build directory.
Is there a trick to let the IDE take the code unknown to itself along into the build directory? Or how else can I deal with this situation? I don't want to close and open the IDE a hundred times a day.
