Hello, I'm currently working on a project as a student training course. We're building a VM to run Java code on embedded devices. The goal of the project is to provide a tool to strip down this VM to the only needed classes from the Java framework (since this VM will finally be burned on some smart devices, with very few memory capacity). The Sun API doesn't allow us to do something like this, so we are using the GNU Classpath Project. The project use his own hierarchy so, while incorporing classes from Classpath, we need to change packages names (the root directory of the project his fr.lifl.rd2p. so everything in java., java.lang for example, will become fr.lifl.rd2p.lang, and so on...). In the process, we need to change import references, and the hardcoded call in some classes for other classes in the API (by example an hardcoded call to java.io.IOException in some procedure prototype needs to be changed).
To help me do this tedious work, I have build a small app, taking a config file with the patterns to substitute in the Classpath hierarchy, and while copy the file in the new hierarchy, do the substitutions. Since the creation of this config file (an very big XML chunk of patterns and strings) is a repetitious process, and I also don't want to spend the rest of the training course on some copy/paste line work, I've build a Swing GUI - a click-o-matic-like for the lines to be substitued. The GNU Classpath project evolves while I'm doing this. And some substitution rules available for today won't be available in future releases of the Classpath project. Some new classes/substitutions will be introduced with each new version... So, I post this message to ask if I'm not missing something in the process, if there is a existing tool or some guidelines to help me keep track of the diff in a streamlined way. Do you have any comments or suggestions ?
