ruby - annotate command "no such load to file" with -R -

-

the annotate command fails when using -r option load additional files before loading models version 2.4.1.beta. files appear found, error still occurs (if use wild-card path first file displayed error). similar error message appears here (https://github.com/ctran/annotate_models/issues/78) solution there use:

gem 'annotate', github: 'ctran/annotate_models'

but if replace annotate in gemfile above, , do:

gem uninstall annotate bundle install

then bundle reports on first line:
updating git://github.com/ctran/annotate_models.git

and later:
using annotate (2.5.0.pre1) git://github.com/ctran/annotate_models.git (at master)

note neither message says "installing". executing annotate ends annotate executable not being found. solutions? (ruby 1.9.2p280, rails 3.2.2)

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...
