Issue Details

I have two different versions of the same LabVIEW project which I would like to compare to find any differences between them.
Is it possible to compare two projects in LabVIEW?


As now, there is no built-in tool in LabVIEW allowing to compare two different project files.
The only possible workarounds could be:

  • compare the two .lvprj files, by opening them with a text editor, since the LabVIEW project file is essentially an xml file
  • compare the hierarchies of the main VIs of the two projects by selecting Tools » Compare » Compare VI Hierarchies
  • compare VIs by selecting Tools » Compare » Compare VIs
  • integrate a source code control provider in LabVIEW
The last three options, however, would allow to compare VIs and not other project items, such as non-LabVIEW files, build specifications, libraries etc.
