Need regex to match word or end of string -


i'm trying contents of string can either of two.

title1: *stuff_to_get*   title2:... title1: *stuff_to_get*

my regex looks this

"title1:\s*?(.+?)title2|$"

the reasoning is: *stuff_to_get* can flush colon or not why include the

"\s*?"

then regex should grab until sees title2 or end of string. appreciated.

alternations (|) apply entire group they're in or entire pattern, if not in groups. haven't grouped alternation anything, version match title1:\s*?(.+?)title2 or end of string , nothing else.

you need group alternation this:

title1:\s*?(.+?)(?:title2|$)

it's little strange have 2 lazy quantifiers together. if want allow white space before *stuff_to_get*, \s* (no ?) little bit more clear: 

title1:\s*(.+?)(?:title2|$)

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
