Failed to build projects with multiple *.ino files.

[Smartype]

With the Arduino IDE, if will merge all ino files to create a cpp file and build that one. But with this plug in , it will try to build every one instead.

[Robot-Will]

Thanks a lot. Actually, I do not know what Arduino IDE does for multiple ino files. I just treat them as c++ source files and compile them separately. Would you give me more information about this topic? If I have more detailed information, I will make this plugin acting more like Arduino IDE.

This file is created from all the .ino, .cpp, .h, .c files in the project directory:

I download your codes and try to compile them, but I failed. You made a great job, and your code are very complex. It's a challenge to me, and I will write codes to parse it in right way.

[blezalex]

you can try a smaller project, two ino files is enough. Make second file call something like " OCR1A =" and you'll get compilation error - error: 'OCR1A' was not declared in this scope.

Thank you for quick response and the plugin, once you find a way to fix this one, i can start using it.

[Robot-Will]

You are right, no declaration error will give.

I think Arduino IDE is for beginners, so it needn't users writing complete source codes, just writing function definitions, and the IDE will combine all source code into one file, then compile the combination. Before compilation， the IDE creates a declaration list and adds the list to the top of the combination file. So Arduino IDE will not give declaration error. I do not read the source code of Arduino IDE, and do not know how it creates the declaration list, but it does a good job.

I did not learn the course of Compilation Principle, so I have no idea how to analyze a complex C++ source code, and current plugin just gives a simple resolution to create declaration lists. So it maybe give error messages when compiling.

However, I think it is not a good habit for programming that just writing function definitions. I read the book "C++ How to program" 8th edition (Paul Deitel and Harvey Deitel), and this book taught me how to write good C++ codes. Write your declarations in header (.h, .hpp) files. When you use the functions, just include the corresponding header files. In your main source code, which includes setup() and loop() functions, do not write extra function definitions, just include header files. That is, you function definition files will be a library, and you can copy these files to SKETCHBOOK FOLDER/libraries/LIB_NAME, you can repeat using this functions just writing #include <HEADER.h>.

Or you can see this issue and start to use this plugin https://github.com/Robot-Will/Stino/issues/3
