Evaluate whole expression under cursor

(1/3) > >>

Hi,
tonight I make patch that sends whole expression under cursor to debugger.
If you often debug code like: getSth()->doSth you will like it ;)

I hope everything in patch is all right because it's bit late.

Here's my test code:

--- Code: ---struct A1
{
A1() : selfRef( *this )
{
alsoMe = this;
}

A1* selfPtr(int a, int b)
{
return this;
}

template<class T>
A1& memTemp( const T& t1, const T& t2 )
{
return *this;
}

static A1* alsoMe;

int someVeryLongInt;
A1& selfRef;
};
A1* A1::alsoMe = 0;

A1 giveAtPlease(int a, int b)
{
return A1();
}

int main()
{
A1 someVeryLongA1;
giveAtPlease( 4,   5 ) . selfRef  . someVeryLongInt;
A1 array[5];
array[2].selfPtr(4, 2) -> selfRef . someVeryLongInt;
A1::alsoMe -> selfRef. memTemp< float> (4, 5.1f).someVeryLongInt;
someVeryLongA1.memTemp< float> (4, 5.1f).someVeryLongInt;
array[4].selfPtr(2,2);
return 0;
}

--- End code ---
As usual I look forward to feedback.

Why not just select the expression, and press "CTRL"? (I have set the option: hover and press ctrl to show the value)

p2rkw:
Now c::b can select text for me :) When I debugging step by step I had to select almost every expression, it started annoying me,
especially when I have to select expression like: object.member every time. Consider that when you select to much (for instance: semicolon at end of line) debugger will not be able to evaluate selected text. For me it's faster to point single word than selecting everything.

Thanks for tip with CTRL, I don't know about this feature, finally I don't have to wait for tooltip ( maybe tooltip delay should be customizable? ;) ).

edit: I forgot  about main reason: when I hover 'member' in expression 'object.member' I want to see value of object.member not value of local variable named member.

1. This is not the right way to do this. Because parsing c/c++ is not an easy task and errors could lead to some bad result as crashing the debugger or putting it in a loop -> crashing c::b. You have to use the code completion. I think there was a patch samewhere doing it. But this requires changes to the sdk.
2. Use spaces not tabs
3. Post your patch on the patch tracker

It is but it is global for all tooltips.

So, if you hover on "object", you will show the value of "object", if you hover on "member", you will did a left search and show the value "object.member"? This sounds great, but as obF said, how did you do the "left search", it could be complex (contains a lot of expressions), and maybe will cause the gdb to crash. :)
