Description Ciprian Khlud 2013-02-27 02:19:47 UTC
Steps to reproduce:
- enable source analysis in preferences
- make your code in a state that you have either warnings or errors in your code (that source analysis can detect them)
- click on the yellow box (in case of warnings) or on the red box (in case of errors)

Actual result:
- nothing happens

Expected result:
- it goes to first error, if no error exists, it goes to first (detected) warning that appears in source

In a similar note: clicking (close to) any warning/error line should select it.

By "goes to" I mean:
- move caret in source to point to where the warning is happening
- auto-open the expansion menu with suggestions for auto-fix

This will simplify this use-case:
- user notices that it inherits an old codebase that doesn't use "var" in it, but it wants to clean it up
- user opens the files one by one
- for every warning it clicks on the bottom-right yellow bar (that points to "change to var" hint) and presses "1", meaning the first fix

Actual result: (for previous use-case) is:
- user clicks in the side bar, looks to the left where is the "wrong line", and after that clicks alt-enter and eventually press 1

It's a good idea that'll give the box some usability.
I'll implement it when I revisit the source analysis UI.
Comment 2 Ciprian Khlud 2013-02-27 10:52:35 UTC
I did notice that after I upgraded to the Git version of NRefactor (and I replaced it in-place inside XS 4.0 installation) that the "hints" bar is working. So just the error-square (on the bottom) is not working.

There are some safe fixes that can be done I think automatically:
- use var always
- remove redundant usings
- remove redundant this.
- remove redundant namespaces (where possible)

If you think that will be done, I can write to you another bug entry.

Also I can confirm reported and you made them as resolved, I tested them and they look fixed (and work much more natural than I expected, so good job!)

I don't think that auto fixes are a good thing.

If someone contributes such a command / option I wouldn't say no. But mangling with source code as default is a bad thing. Even such things like changing eol markers that they're coherent inside a project result in many, many requests to remove that feature ... 

Having something like a dialog - or message bar popping up and asking for such things is another story - that can be done but I don't think we'll be doing it - but the UI of the source analysis isn't finished it was just my first shot. It's up to our interface designers to improve it :)

I have checked this issue with following builds:

All Mac
X.S 4.2.3(build 24)
Mono 3.2.6
X.Android 4.12.0-1

Now I am seeing proper usability for errors and warning. This is the screencast for the same: http://screencast.com/t/cN1g0mwGVFD
