Eclipse has great possibilities to compare files and folders with each other or history.
But I’m also using external tools:
Some time ago I blogged how to use NameChanger (Freeware) under OSX to rename files where the bundle names aren’t named like eclipse bundles (plug-ins) using “name_version“.
Also for creating of target platform – locations I’m using a tool to get unique sets of bundles. My blog „Avoid Duplicate Bundles“ desribes the use of FileMerge (under OSX part of XCode Tools).
Now I was looking for an intelligent tool to see if generated code is identical to an older version. This generated code is not checked into a sourcecode repository, because its always regenerated. Before starting the generation those directories werde cleared, so there’s also no local history in Eclipse.
While testing 4.3.1RC2 of openArchitectureWare I was interestd to see if the generated code is identical to version 4.3.0.
Its not so easy because there are some allowed differences like:
* generation started at: 9. Dezember 2008 08:04:13 CET
Those generation timestamps should be “identical” to lines with another timestamp. FileMerge from OSX was no help, because these files are reported as different.
Next try: Compare Folders compares the size of files and also reports added or missing files. If the generation timestamp hase same length, then the files are identical otherwise not:
… I also dont know if the other content is identical – I need the compare more detailed. I found DeltaWalker where I can do waht I want. But the best of all is:
DeltaWalker is an Eclipse RCP Application 🙂
…and available for OSX, Windows, Linux. Now it was easy to see if the generated code is the same as before:
Create a File – Filter, where lines of different generation timestamps are identical:
Create a Folder- Filter ignoring OSX-specific .DS_Store Files:
Then hitting Compare::
All the same 🙂
– in all my projects no differences found between 4.3.0 and 4.3.1RC2 after re – generation.
Without the File – Filter DeltaWalker lists the differences:
…think that DeltaWalker will be a good helper and a great example for RCP Apps.
