Is there a way to make this Ruby ternary operation evaluate properly? -

-

the following line of code

<% invite.accepted ? { @going, @not_going = 'selected', '' } : { @going, @not_going = '', 'selected' } %>

is attempt @ condensing several operations (evaluating expression , setting values of 2 variables accordingly) single line.

it kicks error, claiming there's unexpected comma.

is there way make work, or overloading poor ternary operator?

(this personal experiment, way. don't mind using simple -- albeit cumbersome -- if/else statement)

edit: following line of code works! i'll check off proper answer can!

<% invite.accepted ? ( @going, @not_going = 'selected', '' ) : ( @going, @not_going = '', 'selected' ) %>

how about:

@going, @not_going = invite.accepted ? ['selected', ''] : ['', 'selected']

w, x = y, z same w, x = [y, z], works fine , there no repetition.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
