improve support for compiler feedback

[lmihalkovic]

Aside from hard errors, the compiler is also outputing warnings that can help users improve the quality if their code. It might be useful to

• display the information in a summarized list form
• jump from the warnings to the exact code location in the correct editor tab
• display a warning icon next to the line in question in the editor
• make the behavior optional so as not to overwhelm beginner level users

Currently, the compiler highlights one line (not sure which one, the first or last error and/or warning). It would indeed be good if this were expanded to highlight all errors and warnings and then jump to the first one. Using an icon in addition to the line highlight (and probably also using different colors) would help distinguishing between both as well.

display the information in a summarized list form

What did you have in mind here? A table-like form like eclipse uses?

jump from the warnings to the exact code location in the correct editor tab

You mean that clicking an error in the log window jumps to it?

Compiler was bailing on first error. I changed it to collect them all. As I explained somewhere it is not a big deal to do that and ensure the output is not "free-floating" from editor to editor when working with several.

• simple list either as a separate console view (not in your face) or via the QuickAccess (less visible)
• yes jump from console out to location (~works)

@mbanzi In a school/teaching environment, it makes sense to me that the TA/Teacher would be able to have a given script that collects her 'best practices'. Then the student would compile and see what kind of best practices recommendations come out. Being able to have that info in a separate list view from the standard console is just a small extra step. This is a scheme I wanted to test using google's python cpp lint, and one of the items I alluded to but never explained in my email.

Missing warnings. There are so many i think they are best left for manual access rather than coloring each.

Still think it would be useful.
