Add Instance Probes

[JoeAtHPI]

Instance Probes are a new kind of annotation which can be added to instance variable names in class' definitions.

They will add assignment probes throughout all methods of the responding class in which the variable gets directly assigned. For example, selecting 'foo' will add probes to all lines containing 'foo := ' instead of 'foo: '. Shadowing ignored.
In the instance probe, which gets displayed in class' defintions, users will see the chronologically ordered trace of all values of the added assignment probes. When deleting one of those linked probes, its values also disappear from the instance probe trace. Deleting the instance probe will delete the linked probes.

This feature used to be achieved by manually adding probes to only assignments and displaying the example in the ProbeLog.

Future Todos are:

• Serialise Instance Variable Probes #160
• Reuse existing assignment probes when creating instance probes  #161

@codeZeilen tests failing due to compiledmethod not knowing parseTree which uses RBParser. add it to baseline or is there another existing parser which gets the intervals like i intend to?

@JoeAtHPI Ohm should be able to handle this. You may want to look at BPSourceMapping and BPSourceMapNode and the place where they are used. You should be able to create a source map with BPSourceMapping new value: .... Then you can simply take the first element of the source map and there the first node. This is the top-most node in the parse tree. Each node contains an interval which you can use to get the source section from the original string.

If you can really not get this to work you may add the dependency to RBParser (but, as we have Ohm it would be preferable to avoid this additional dependency to a parser). :)

[codeZeilen]

First noted/questions. Will come back later for more. :)

[codeZeilen]

Several of these example mining methods disappeared. Is this intentional? Where did they go? :)

[JoeAtHPI]

No, will add them back later!

[codeZeilen]

Why is trunk needed?

[JoeAtHPI]

will revert this

[codeZeilen]

Is this intentional?

[JoeAtHPI]

no, i think the readme got a bit messed up when dev was merged

[codeZeilen]

You can use gather for this. :)
