Share My Creation B4Rh2xml UI Simple tool to create B4R xml file from B4R header file

Hi all,

I'm trying to learn how to create B4R libraries and convert libraries that I wrote with Arduino IDE for Arduino and ESP8266. I have to convert six libraries already working on Arduino IDE and all with sample code, and one library is about 1600 lines of code, so I start my work here for B4R conversion.

On this direction I used the B4Rh2xml tool made by Erel to create B4R xml files from B4R header files.

Since this tool is a command line, I decided to create a simple GUI version with B4J.

This simple tool internally uses B4Rh2xml from Erel. It is very easy to use, just copy the Jar file on your hard drive on any position you want, launch it, push a button, at this point you are prompted to choose the header file on your hard drive, select it and then if all goes well, the tool create the xml file in the same directory of the header file. If you see errors, then your header file is not in correct format, this even will not works in B4Rh2xml NONUI.

The first time you press a button after the tool started, it point to Jar file directory, after this the tool remember your last directory, this happens until it restarts. (if averyone interested I can change it to save permanently last directory on exit, so next time you start, it remember last directory before close it)

Anyway, I decided to release both the simple source code, either the entire B4J project and also the already compiled executable jar file.

I hope you'll use this tool when creating your B4R libraries as it is exactly the Erel's B4Rh2xml but a GUI version.

Comments and improvements are welcome, but sorry for my not good english.

Hello everyone,
and good programming with B4X tools !!!
