Hi Vajk,
right, the class files are required to evaluate all the coverage data
represented in the reports (or the Eclipse editors). Exec files itself
do not contain any meta information of the classes beside the class
names an an id calculated from the class file hash.
The coloring of backgrounds is called "annotations" in Eclipse RCP and
used all kind of highlighting (error, warnings, search results, etc).
The EclEmma usage of the APIs can be found in the package
com.mountainminds.eclemma.internal.ui.annotation:

Thanks for pointing to the API Marc.
So, just to clarify, JaCoCo analyzes the class files even when it is
merely displaying the coverage information.
I was initially assuming, that the exec format holds the file path and
the source line for each covered section.
If you cold guide me one final time, where to search/find code related
to coloring the backgrounds of java files based on the coverage
results, that would be mega helpful. Thank you for your time, and your
quick response once again.
thx,
Vajk

Hi Vajk,
there is no formal specification of the format, but there are APIs
to read and write these files (see ExecutionDataReader/Writer
class). Basically a execution data file contains a probe array
(true/false) per class. To derive coverage information from those
files JaCoCo analyzes the original class files. As you need class
files for JaCoCo/EclEmma I don't think you can feed-in coverage
data from other runtime code than Java classes.

Back in the days when I coded in Java, EclEmma and JaCoCo was
pretty helpful to review coverage with unittests, or just
after an adhoc testing.
I was wondering if there is a format specification for the
JaCoCo exec file format, and if theoretically, dumping a
python coverage report into that format would easily show up
in the editors..
I know that it might be a though question, but I'd ask it
before spending hours with figuring it out on my own. You
might have a better sense on how much work this would be.
Thx,
Vajk
