compare two different versions of a composition?

   

This is done using the Command Menu `Compare' button, which does a structural difference between two versions of the the same composition. You need to bring up two different versions of the composition on the screen. Currently, the easiest way is to make another copy the current version (see section 2.15), which we call the `destination' version. Then go back to an old version of the composition (see section 3.5) in the duplicate window.

Select the source (the old version), then the destination (the current version), and finally click on the `Compare' button in the Command Menu.

 


:  Source Composition (Original version).

 


:  Destination Composition (New version).

That is:

Deleted entities in the source composition (where you clicked first) will be marked with shaded background or with color background (if you gave the `-c' command line option). Where there have been changes from the source to the destination, these items will be marked in the destination composition by shading. Items which have been added will also be so marked. You can customize the select backgrounds; see section 3.15.

Figure 3.10 is selected first and thus is the `original version' and figure 3.11 is the `new version'. In figure 3.11 we have inserted a new section, ``Architecture'', which has been shaded light grey, and the top level changes to the name field and the abstract part is shaded in a darker grey.

To refresh the view and remove the coloring, simply use the ctrl-l key.
