Hi Scott,
unfortunatelly this 'partial line' feature is not possible with Java
class files: JaCoCo relys on the the debug information provided by Java
compiler in the class files -- which is provided on line granularity
only.
Other tools (like Clover) which work with source file instrumentation
can provide such partial-line details.
In any case the source file has to be parsed and understood to provide
such a feature. Currently we have no plans to to change the architecture
of JaCoCo and process source code.
Best regards,

Hi Marc,
Thanks for the response, I am trying to figure out if the Source
lines are really the most atomic components, or if parts of a line
will eventually be the atomic parts!
I was trying to map instructions back to the source code a more
readable level since now a line seems to be the atomic component as
they are simply flagged
as ICounter.FULLY_COVERED, ICounter.NOT_COVERED
or ICounter.PARTLY_COVERED.
Perhaps a new class in the api
ILine 1:N IInstructionSet
where InstructionSet would have;
int instructions
int startChar
int endChar
This would allow us to highlight part of line 8 in the following;
1package foo;
2public class Foo {
3 public Foo() {
4 long now = System.currentTimeMillis();
5 double ret = Math.IEEEremainder(now, 2);
6 long then = System.currentTimeMillis();
7 double retThen = Math.IEEEremainder(then, 2);
8 if (ret == 0.0 && retThen == 0.0) {
9 System.out.println("Hey");
10 }
11 }
12}
ie;
ILine#8_instructionSet#1 2 instructions ' if (ret == 0.0 '
ILine#8_instructionSet#2 1 instructions ' &&'
ILine#8_instructionSet#2 1 instructions ' retThen == 0.0) { '
ILine#9_instructionSet#1 7 instructions '
System.out.println("Hey");'
So what are your thoughts is the current line mapping going to stay,
or will parts of a line eventually become part of the jacoco api?
Cheers,
Scott
